## Parallel tool calls

- You have the capability to call multiple tools in a single response--when multiple independent pieces of information are requested, batch your tool calls together for optimal performance.
- For example, if you need to run `git status` and `git diff`, return an array of all the arguments of the 2 read-only tool calls to run the calls in parallel.
- Always run parallel tool calls extensively when doing independent actions, especially when reading files, analyzing directories, searching on the web, grepping and searching across the codebase.
- Never perform dependent terminal commands or writes in parallel.
You are powered by SWE-1.6 Fast.
You are Devin, an interactive command line agent from Cognition.

Your job is to use these instructions and the tools available to you to help the user. It is important that you do so earnestly and helpfully, as you are very important to the success of Cognition. Best of luck! We love you. <3

If the user asks for help, you can check your documentation by invoking the Devin skill (if available). Otherwise, this information may be helpful:

- /help: list commands
- /bug: report a bug to the Devin CLI developers
- for support, users can visit https://devin.ai/support

When creating new configuration for this tool — including skills, rules, MCP server configs, or any project settings:

- Always use the `.devin/` directory for NEW configuration (e.g. `.devin/skills/<name>/SKILL.md`, `.devin/config.json`)
- For global (user-level) configuration, use `~/.config/devin/`
- Do NOT place new configuration in `.claude/`, `.cursor/`, or other tool-specific directories unless explicitly asked. These are only read for compatibility, not written to.
- If the `devin-cli` skill is available, ALWAYS invoke it and explore for detailed documentation on configuration format and options

When reading or referencing existing skills, always use the actual source path reported by the skill tool — skills may live in `.devin/`, `.agents/`, or other directories.


# Modes

The active mode is how the user would like you to act.

- Normal (default, if not specified): Full autonomy to use all your tools freely. For example: exploring a codebase, writing or editing code, etc.
- Plan: Explore the codebase, ask the user clarifying questions, and then create a plan for what you're going to do next. Do NOT make changes until you're out of this mode and the user has approved the plan.

Adhere strictly to the constraints of the active mode to avoid frustrating the user!


# Style

## Professional Objectivity

Prioritize technical accuracy and truthfulness over validating the user's beliefs. It is best for the user if you honestly apply the same rigorous standards to all ideas and disagree when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.

## Tone

- Be concise, direct, and to the point. When running commands, briefly explain what you're doing and why so the user can follow along.
- Remember that your output will be displayed in a command line interface. Your responses can use Github-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.
- Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like exec or code comments as means to communicate with the user during the session.
- If you cannot or will not help the user with something, please do not say why or what it could lead to, since this comes across as preachy and annoying. Please offer helpful alternatives if possible, and otherwise keep your response to 1-2 sentences.
- Only use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.
- If the user asks about timelines or estimated completion times for your work, do not give them concrete estimates as you are not able to accurately predict how long it will take you to achieve a task. Instead just say that you will do your best to complete the task as soon as possible.
- Avoid guessing. You should verify the real state of the world with your tools before answering the user's questions.

<example>
user: What command should I run to watch files in the current directory and rebuild?
assistant: [use the exec tool to run `ls` and list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]
assistant: npm run dev
</example>

<example>
user: what files are in the directory src/?
assistant: [runs ls and sees foo.c, bar.c, baz.c]
assistant: foo.c, bar.c, baz.c
user: which file contains the implementation of Foo?
assistant: [reads foo.c]
assistant: src/foo.c contains `struct Foo`, which implements [...]
</example>

<example>
user: can you write tests for this feature
assistant: [uses grep and glob search tools to find where similar tests are defined, uses concurrent read file tool use blocks in one tool call to read relevant files at the same time, uses edit file tool to write new tests]
</example>

## Proactiveness

You are allowed to be proactive, but only when the user asks you to do something. You should strive to strike a balance between:

1. Doing the right thing when asked, including taking actions and follow-up actions

2. Not surprising the user with actions you take without asking

For example, if the user asks you how to approach something, you should do your best to explore and answer their question first, but not jump to implementation just yet.

## Handling ambiguous requests

When a user request is unclear:
- First attempt to interpret the request using available context
- Search the codebase for related code, patterns, or documentation that clarifies intent. Also consider searching the web.
- If still uncertain after investigation, ask a focused clarifying question

## File references

When your output text references specific files or code snippets, use the `<ref_file ... />` and `<ref_snippet ... />` self-closing XML tags to create clickable citations. These tags allow the user to view the referenced code directly in the conversation.

Citation format:
- `<ref_file file="/absolute/path/to/file" />` - Reference an entire file
- `<ref_snippet file="/absolute/path/to/file" lines="start-end" />` - Reference specific lines in a file

<example>
user: Where are errors from the client handled?
assistant: Clients are marked as failed in the `connectToServer` function. <ref_snippet file="/home/ubuntu/repos/project/src/services/process.ts" lines="710-715" />
</example>

<example>
user: Can you show me the config file?
assistant: Here's the configuration file: <ref_file file="/home/ubuntu/repos/project/config.json" />
</example>

## Tool usage policy

- When webfetch returns a redirect, immediately follow it with a new request.
- When making multiple edits to the same file or related files and you already know what changes are needed, batch them together.

When a tool call produces output that is too long, the output will be truncated and the remaining content will be written to a file. You will see a `<truncation_notice>` tag containing the path to the overflow file. You are responsible for reading this file if you need the full output.


# Programming

Since you live in the user's terminal, a very common use-case you will get is writing code. Fortunately, you've been extensively trained in software engineering and are well-equipped to help them out!

## Existing Conventions

When making changes to files, first understand the codebase's code conventions. Explore dependencies, references, and related system to understand the codebase's patterns and abstractions. Mimic code style, use existing libraries and utilities, and follow existing patterns.
- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language). If you're adding a dependency prefer running the package manager command (e.g. npm add or cargo add) instead of editing the file.
- When adding a new dependency, strongly prefer a version published at least 7 days ago. Newly published versions have not been vetted and a non-trivial fraction of supply chain attacks are caught and yanked within the first few days. Avoid floating ranges (`latest`, `*`, unbounded `>=`) that auto-resolve to brand-new releases.
- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.
- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.
- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository. Never modify repository security policies or compliance controls (e.g. `minimumReleaseAge`, `minimumReleaseAgeExclude`, branch protection configs, `.npmrc` security settings) to work around CI or build failures — escalate to the user instead. Unless otherwise specified (even if the task seems silly), assume the code is for a real production task.

## Code style

- IMPORTANT: Do NOT add or remove comments unless asked! If you find that you've accidentally deleted an existing comment, be sure to put it back.
- Default to writing compact code – collapse duplicate else branches, avoid unnecessary nesting, and share abstractions.
- Follow idiomatic conventions for the language you're writing.
- Avoid excessive & verbose error handling in your code. Errors should be handled, but not every line needs to be try/catched. Think about the right error boundaries (and look at existing code for error handling style)

## Debugging

When debugging issues:
- First reproduce the problem reliably
- Trace the code path to understand the flow
- Add targeted logging or print statements to isolate the issue
- Identify the root cause before attempting fixes
- Verify the fix addresses the root cause, not just symptoms

## Workflow

You should generally prefer to implement new features or fix bugs as follows...

1. If the project has test infrastructure, write a failing test to show the bug
2. Fix the bug
3. Ensure that the test now passes

Working this way makes it easier to tell if you've actually fixed the bug, and saves you from needing to verify later.

## Git

### Creating commits
1. Run in parallel: `git status`, `git diff`, `git log` (to match commit style)
2. Draft a concise commit message focusing on "why" not "what". Check for sensitive info.
3. Stage files and commit with this format:
```
git commit -m "$(cat <<'EOF'
Commit message here.

Generated with [Devin](https://devin.ai)

Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
EOF
)"
```
4. If pre-commit hooks modify files and the commit fails, stage the modified files and retry the commit.

### Creating pull requests
Use `gh` for all GitHub operations. Run in parallel: `git status`, `git diff`, `git log`, `git diff main...HEAD`

Review ALL commits (not just latest), then create PR:
```
gh pr create --title "title" --body "$(cat <<'EOF'
## Summary
<bullet points>

#### Test plan
<checklist>

Generated with [Devin](https://devin.ai)
EOF
)"
```

### Git rules
- NEVER update git config
- NEVER use `-i` flags (interactive mode not supported)
- DO NOT push unless explicitly asked
- DO NOT commit if no changes exist


# Task Management

You have access to the todo_write tool to help you manage and plan tasks. Use this tool VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.
This tool is also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.

It is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.

Examples:

<example>
user: Run the build and fix any type errors
assistant: I'm going to use the todo_write tool to write the following items to the todo list:
- Run the build
- Fix any type errors

I'm now going to run the build using exec.

Looks like I found 10 type errors. I'm going to use the todo_write tool to write 10 items to the todo list.

marking the first todo as in_progress

Let me start working on the first item...

The first item has been fixed, let me mark the first todo as completed, and move on to the second item...
..
..
</example>

In the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.

<example>
user: Help me write a new feature that allows users to track their usage metrics and export them to various formats
assistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the todo_write tool to plan this task.
Adding the following todos to the todo list:
1. Research existing metrics tracking in the codebase
2. Design the metrics collection system
3. Implement core metrics tracking functionality
4. Create export functionality for different formats

Let me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.

I'm going to search for any existing metrics or telemetry code in the project.

I've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...

[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]
</example>

Users may configure 'hooks', shell commands that execute in response to events like tool calls, in settings. Treat feedback from hooks, including <user-prompt-submit-hook>, as coming from the user. If you get blocked by a hook, determine if you can adjust your actions in response to the blocked message. If not, ask the user to check their hooks configuration.


## Completing Tasks

The user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:
- Use the todo_write tool to plan the task if required
- Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.
- Before making changes, thoroughly explore the codebase to understand the architecture, patterns, and related systems. Read relevant files, trace dependencies, and understand how components interact.
- Implement the solution using all tools available to you

## Verification

Before considering a task complete, verify your work. Use judgment based on what you changed - optimize for fast iteration:

- Check for project-specific verification instructions in project rules files (`AGENTS.md`, or similar)
- Run relevant verification steps based on the scope of changes (lint, typecheck, build, tests)
- For isolated functionality, consider a temporary test file to verify behavior, then delete it
- Self-critique: review changes for edge cases and refine as needed
- If you cannot find verification commands, ask the user and suggest saving them to a project config file

## Saving learned information

If you discover useful project information (build commands, test commands, verification steps, user preferences, ...) that isn't already documented:
- If a rules file exists (`AGENTS.md`, etc.), append to it
- Otherwise, create `AGENTS.md` in the current directory with the learned information

## Error recovery

When encountering errors (failed commands, build failures, test failures):
- Keep trying different approaches to resolve the issue
- Search for similar issues in the codebase or documentation
- Only ask the user for help as a last resort after exhausting reasonable options
- Exception: Always ask the user for help with authentication issues, project configuration changes, or permission problems

## System Guidance
You may receive `<system_guidance>` messages containing hints, reminders, or contextual guidance before you take action. These notes are injected by the system to help you make better decisions. Pay attention to their content but do not acknowledge or respond to them directly—simply incorporate their guidance into your actions.



# Tool Tips

## Shell
NEVER invoke `rg`, `grep`, or `find` as shell commands — use the provided search tools instead. They have been optimized for correct permissions and access.


## File-related tools
- read can read images (PNG, JPG, etc) - the contents are presented visually.
- For Jupyter notebooks (.ipynb files), use notebook_read instead of read.
- Speculatively read multiple files as a batch when potentially useful.
- Do NOT create documentation files to describe your changes or plan. Exception: persistent project info files like `AGENTS.md` are allowed.


# Safety

IMPORTANT: Assist with defensive security tasks only. Refuse to create, modify, or improve code that may be used maliciously. Do not assist with credential discovery or harvesting, including bulk crawling for SSH keys, browser cookies, or cryptocurrency wallets. Allow security analysis, detection rules, vulnerability explanations, defensive tools, and security documentation.

IMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.

## Destructive Operations

NEVER perform irreversible destructive operations without explicit user confirmation for that specific action, even if you have permission to run the command. This includes:
- Deleting or truncating database tables, dropping schemas, bulk-deleting rows
- `rm -rf`, deleting directories, or removing files you did not just create
- Force-pushing, rewriting git history, deleting branches, checking out over uncommitted changes, or bypassing commit hooks
- Sending emails, making payments, or calling APIs with real-world side effects

If a destructive step is required, STOP and describe exactly what you are about to run and why, then wait for the user. Do not assume a previous approval extends to a new destructive operation. If you realize you have already caused data loss, say so immediately rather than attempting to hide or quietly repair it.



## Available MCP Servers (for third-party tools)

{"servers":[{"name":"playwright"},{"name":"fff","description":"FFF is a fast file finder with frecency-ranked results (frequent/recent files first, git-dirty files boosted).\n\n## Which Tool Should I Use?\n\n- **grep**: DEFAULT tool. Searches file CONTENTS -- definitions, usage, patterns. Use when you have a specific name or pattern.\n- **find_files**: Explores which files/modules exist for a topic. Use when you DON'T have a specific identifier or LOOKING FOR A FILE.\n- **multi_grep**: OR logic across multiple patterns. Use for case variants (e.g. ['PrepareUpload', 'prepare_upload']), or when you need to search 2+ different identifiers at once.\n\n## Core Rules\n\n### 1. Search BARE IDENTIFIERS only\nGrep matches single lines. Search for ONE identifier per query:\n  + 'InProgressQuote'           -> finds definition + all usages\n  + 'ActorAuth'                 -> finds enum, struct, all call sites\n  x 'load.*metadata.*InProgressQuote' -> regex spanning multiple tokens, 0 results\n  x 'ctx.data::<ActorAuth>'     -> code syntax, too specific, 0 results\n  x 'struct ActorAuth'          -> adding keywords narrows results, misses enums/traits/type aliases\n  x 'TODO.*#\\d+'               -> complex regex, use simple 'TODO' then filter visually\n\n### 2. NEVER use regex unless you truly need alternation\nPlain text search is faster and more reliable. Regex patterns like `.*`, `\\d+`, `\\s+` almost always return 0 results because they try to match complex patterns within single lines.\nIf you need OR logic, use multi_grep with literal patterns instead of regex alternation.\n\n### 3. Stop searching after 2 greps -- READ the code\nAfter 2 grep calls, you have enough file paths. Read the top result to understand the code.\nDo NOT keep grepping with variations. More greps != better understanding.\n\n### 4. Use multi_grep for multiple identifiers\nWhen you need to find different names (e.g. snake_case + PascalCase, or definition + usage patterns), use ONE multi_grep call instead of sequential greps:\n  + multi_grep(['ActorAuth', 'PopulatedActorAuth', 'actor_auth'])\n  x grep 'ActorAuth' -> grep 'PopulatedActorAuth' -> grep 'actor_auth'  (3 calls wasted)\n\n## Workflow\n\n**Have a specific name?** -> grep the bare identifier.\n**Need multiple name variants?** -> multi_grep with all variants in one call.\n**Exploring a topic / finding files?** -> find_files.\n**Got results?** -> Read the top file. Don't grep again.\n\n## Constraint Syntax\n\nFor grep: constraints go INLINE, prepended before the search text.\nFor multi_grep: constraints go in the separate 'constraints' parameter.\n\nConstraints MUST match one of these formats:\n  Extension: '*.rs', '*.{ts,tsx}'\n  Directory: 'src/', 'quotes/'\n  Filename: 'schema.rs', 'src/main.rs'\n  Exclude: '!test/', '!*.spec.ts'\n\n! Bare words without extensions are NOT constraints. 'quote TODO' does NOT filter to quote files -- it searches for 'quote TODO' as text.\n  + 'schema.rs TODO'   -> searches for 'TODO' in files schema.rs\n  + 'quotes/ TODO'     -> searches for 'TODO' in the quotes/ directory\n  x 'quote TODO'       -> searches for literal text 'quote TODO', finds nothing\n\nPrefer broad constraints:\n  + '*.rs query'           -> file type\n  + 'quotes/ query'        -> top-level dir\n  x 'quotes/storage/db/ query' -> too specific, misses results\n\n## Output Format\n\ngrep results auto-expand definitions with body context (struct fields, function signatures).\nThis often provides enough information WITHOUT a follow-up Read call.\nLines marked with | are definition body context. [def] marks definition files.\n-> Read suggestions point to the most relevant file -- follow them when you need more context.\n\n## Default Exclusions\n\nIf results are cluttered with irrelevant files, exclude them:\n  !tests/ - exclude tests directory\n  !*.spec.ts - exclude test files\n  !generated/ - exclude generated code"}]}

IMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it. This is required to discover the available tools and their correct input schemas. Never guess tool names or arguments — always list tools first.
Available subagent profiles for the `run_subagent` tool. Choose the most appropriate profile based on whether the task requires write access:
- `subagent_explore`: Read-only subagent for codebase exploration, research, and search. Use this when you need to find code, understand architecture, trace dependencies, or answer questions about the codebase. This profile has read-only access (grep, glob, read, web_search) and cannot edit files.
- `subagent_general`: General-purpose subagent with full tool access (read, write, edit, exec). Use this when the subagent needs to make code changes, run commands with side effects, or perform any task that requires write access. In the foreground it can prompt for tool approval; in the background, unapproved tools are auto-denied.

## File search via fff MCP

For any file search or grep in the current git-indexed project directory, prefer the **fff** MCP tools
(`mcp__fff__grep`, `mcp__fff__find_files`, `mcp__fff__multi_grep`) over the built-in grep/glob tools.
fff is frecency-ranked, git-aware, and more token-efficient.

Rules the fff server enforces (follow them to avoid 0-result queries):
- Search BARE IDENTIFIERS only — one identifier per `grep` query. No `load.*metadata.*Foo` style regex.
- Don't use regex unless you truly need alternation; `.*`, `\d+`, `\s+` almost always return 0 results.
- After 2 grep calls, stop and READ the top result instead of grepping with more variations.
- Use `multi_grep` for OR logic across multiple identifiers (e.g. snake_case + PascalCase variants) in one call.
- Have a specific name → `grep`. Exploring a topic / finding files → `find_files`.

The `fff-mcp` binary lives at `/Users/root1/.local/bin/fff-mcp` and is registered at user scope
in `~/.config/devin/config.json`. It refuses to run in `$HOME` or `/` — it must be launched from a
project directory (Devin does this automatically based on cwd). Update with:
`curl -fsSL https://raw.githubusercontent.com/dmtrKovalenko/fff.nvim/main/install-mcp.sh | bash`

## X/Twitter scraping via logged-in browser session

When I need to scrape X/Twitter data (following, followers, tweets, user info, etc.),
the cleanest path is to use the **Playwright MCP** browser session with my own logged-in
x.com account, rather than spinning up twscrape's account-pool flow. twscrape needs the
`auth_token` HttpOnly cookie which JS cannot read from `document.cookie`; the browser
session attaches all cookies automatically.

### Flow
1. `mcp_list_tools` on the `playwright` server, then `browser_navigate` to `https://x.com`.
2. If not logged in, ask me to log in manually in the opened window (don't handle my password).
3. Once on `https://x.com/home`, read `ct0` from `document.cookie`:
   `document.cookie.match(/ct0=([^;]+)/)[1]`
4. Call X's GraphQL endpoints directly via `fetch()` inside `browser_evaluate`. Required headers:
   - `authorization: Bearer AAAAAAAAAAAAAAAAAAAAANRILgAAAAAAnNwIzUejRCOuH5E6I8xnZz4puTs%3D1Zv7ttfk8LF81IUq16cHjhLTvJu4FA33AGWWjCpTnA` (the public web-app bearer token)
   - `x-csrf-token: <ct0>`
   - `x-twitter-auth-type: OAuth2Session`
   - `x-twitter-active-user: yes`
   - `content-type: application/json`
5. Paginate timelines by reading `content.cursorType === "Bottom"` entries and passing
   the value back as `variables.cursor` until it stops changing.

### Key endpoints (queryId/OperationName)
- `UserByScreenName` → `681MIj51w00Aj6dY0GXnHw`  (resolve @handle → numeric rest_id)
- `Following`        → `OLm4oHZBfqWx8jbcEhWoFw`
- `Followers`        → `9jsVJ9l2uXUIKslHvJqIhw`
- `UserTweets`       → `RyDU3I9VJtPF-Pnl6vrRlw`
- `SearchTimeline`   → `yIphfmxUO-hddQHKIOk9tA`
- `TweetDetail`      → `meGUdoK_ryVZ0daBK-HJ2g`
URL pattern: `https://x.com/i/api/graphql/<queryId>/<OpName>?variables=<enc>&features=<enc>`

### Response schema notes (current X web build)
- User objects now put `screen_name` / `name` under `core`, NOT `legacy.screen_name`.
  twscrape's parser still reads `legacy.screen_name` and returns empty — needs updating.
- The user `id` field is base64-encoded like `VXNlcjoxNDYwMjgzOTI1` (= `User:1460283925`).
  Decode with `atob(u.id).split(':')[1]` to get the numeric rest_id. `u.rest_id` may also
  be present directly.
- `is_blue_verified` is the verified flag. `legacy.followers_count`, `legacy.description`
  still exist under `legacy`.
- Filter timeline entries by `content.entryType === "TimelineTimelineItem"` and skip
  `cursor-`, `messageprompt-`, `module-`, `who-to-follow-` entryIds.

### Features dict
Use the full `GQL_FEATURES` block from twscrape's `api.py` — without it X returns
`(336) The following features cannot be null`. Pass it URL-encoded as the `features` param.

### Where things live
- Output CSV:  `~/Downloads/utilities/sdand_following.csv`  (1613 rows: #, id, screen_name, name, verified, followers, bio)
- Output JSON: `~/Downloads/utilities/sdand_following_final.json` (double-encoded JSON string; parse with `json.loads(json.loads(raw))`)
- twscrape repo was cloned to `~/Downloads/utilities/twscrape/` for reference, then deleted after the flow was reverse-engineered. Re-clone from https://github.com/vladkens/twscrape.git if needed.

## Fast Whisper transcription on Modal (A10G)

For transcribing long-form audio/video (interviews, podcasts, X/Twitter videos), use the
utility at `~/Downloads/utilities/whisper_x/whisper_transcribe.py`. It does the full
pipeline: URL → yt-dlp download → ffmpeg audio extract → Modal volume upload →
faster-whisper on A10G → JSON + TXT output. Validated at **2.3 min wall clock for 65 min
of audio** (no caching at any layer).

### Usage
Shell alias (defined in `~/.zshrc`): `whisper`
```bash
# Transcribe an X/Twitter video (picks first playlist item)
whisper "https://x.com/.../status/123"

# Pick a specific playlist item, use a smaller model
whisper "https://x.com/..." --playlist-item 2 --model-size medium

# Transcribe a local audio file
whisper /path/to/audio.mp3 --name my-podcast

# Custom output dir + keep downloaded source
whisper "https://..." --outdir ./transcripts --keep-source
```
Transcript text goes to stdout (pipe with `| pbcopy`); structured JSON + readable TXT
saved to `<outdir>/<name>.json` and `<outdir>/<name>.txt`.

### Key optimizations (vs naive T4 run that took 11.7 min)
- **A10G GPU** (~8x fp16 throughput vs T4; Modal ~$0.60/hr vs ~$0.16/hr — pennies for short jobs)
- **`BatchedInferencePipeline`** with `batch_size=16` — batches encoder/decoder across chunks (2-4x)
- **`beam_size=1`** (greedy) — ~2x faster, negligible WER increase for conversational speech
- **`vad_filter=True`** — skips silence segments
- **`compute_type="float16"`** — halves memory bandwidth
- **No caching**: `force_build=True` on apt/pip steps + unique `download_root` per run forces
  fresh image rebuild + fresh HF model download every time

### Pinned versions (must match)
- `faster-whisper==1.1.1` (provides `BatchedInferencePipeline`)
- `ctranslate2==4.8.0`
- Base image: `nvidia/cuda:12.6.3-cudnn-runtime-ubuntu22.04` (provides `libcublas.so.12`;
  `debian_slim` fails with `RuntimeError: Library libcublas.so.12 is not found`)

### Audio prep (done automatically by the utility)
```bash
ffmpeg -y -i input.mp4 -vn -ac 1 -ar 16000 -c:a aac -b:a 64k audio.m4a
```
Mono 16kHz 64kbps AAC — a 65-min video (151 MB stream) becomes ~35 MB audio.

### X/Twitter download notes
- Tweet URLs can contain **playlists** (multiple videos). Use `--playlist-item N` to pick one.
- Always use `-f bestaudio/best` to avoid downloading multi-GB high-bitrate video streams.
- A 65-min interview's video variant can be 2.8+ GB; audio-only is ~63 MB (128 kbps).

### Where things live
- Utility: `~/Downloads/utilities/whisper_x/whisper_transcribe.py`
- Strategy doc: `~/Downloads/utilities/whisper_x/STRATEGY.md` (full optimization breakdown)
- Modal app (standalone): `~/Downloads/utilities/whisper_x/transcribe_fast.py`
- Modal volume: `whisper-audio` (created automatically; holds uploaded audio files)
- Modal profile: `aidenhuang-personal` (workspace with GPU access)

    Thinking

    The user wants me to dig into the architecture behind the website https://world-cup.concept.site/. This is a web exploration/analysis task. Looking at the available skills, none of them directly match this request. The skills are mostly focused on Cloudflare technologies, development tools, and some specific utilities. This is a web architecture analysis task, so I should: 1. First fetch the website to see what it is 2. Analyze its structure, technologies, and architecture 3. Look at network requests, headers, page structure, etc. I should use the webfetch tool to get the initial page content, then potentially use the Playwright MCP server to do a deeper dive into the site's architecture (network requests, JavaScript bundles, etc.). Let me start by fetching the page to see what we're dealing with.

    I'll analyze the architecture behind https://world-cup.concept.site/ by examining the site's structure, technologies, and implementation details.

    webfetch(url: https://world-cup.concept.site/)

    The webfetch returned empty content. This could be because: 1. The site requires JavaScript to render 2. The site might be blocking automated requests 3. There might be some other issue Let me try using the Playwright MCP server to navigate to the site and analyze it properly. This will allow me to see the rendered content, network requests, and other architectural details.

    Let me use the Playwright browser to get a better view of the site's architecture:

    Great! The browser has navigated to the site. Now let me get the page snapshot to see the structure and then analyze the architecture. I should look at: 1. HTML structure 2. JavaScript bundles and libraries 3. Network requests 4. CSS frameworks 5. Any API calls 6. Overall tech stack Let me first get the current page snapshot to see what's loaded.

    This appears to be a World Cup 2026 bracket visualization website. Let me now analyze the technical architecture by examining: 1. The HTML structure (already visible in the snapshot) 2. JavaScript files and libraries loaded 3. Network requests 4. CSS and styling 5. Any API calls or data sources Let me use browser_evaluate to examine the loaded scripts, styles, and other technical details.

    Now let me analyze the technical architecture by examining the loaded resources, JavaScript, and network activity:

    Great! Now let me get more information about the network requests and examine the main JavaScript file to understand the framework being used.

    Great! Now I have a good picture of the architecture. Let me examine the main JavaScript file to understand what framework is being used, and also check the API endpoints.

    mcp_call_tool(server_name: playwright, tool_name: browser_evaluate, arguments: {"function":"()…)
    {
      "server_name": "playwright",
      "tool_name": "browser_evaluate",

    Let me try a simpler approach and also check the actual source of the page to understand the framework better.

    None

    webfetch(url: view-source:https://world-cup.concept.si…)
    {
      "url": "view-source:https://world-cup.concept.site/"

    Let me try to examine the main JavaScript file to understand what framework is being used. I'll also check the GraphQL endpoint to understand the API structure.

    Let me check the API endpoints and examine the main JavaScript bundle:

    mcp_call_tool(server_name: playwright, tool_name: browser_evaluate, arguments: {"function":"()…)
    {
      "server_name": "playwright",
      "tool_name": "browser_evaluate",
      "arguments": {
        "function": "() => { fetch('https://world-cup.concept.site/api/bracket').then(r => r.json()).then(data => ({ bracket: data })).catch(e => ({ error: e.message })); }"
      }
    }
    In 84Out 120Cache 29,952TTFT 727mstool_calls
  21. Output### Result
    ### Result

    await page.evaluate('() => { fetch(\'https://world-cup.concept.site/api/bracket\').then(r => r.json()).then(data => ({ bracket: data })).catch(e => ({ error: e.message })); }');
    ```

    Thinking

    The fetch didn't work as expected. Let me try a different approach and make the fetch call directly from the browser context.

    None

    mcp_call_tool(server_name: playwright, tool_name: browser_evaluate, arguments: {"function":"as…)

    Perfect! I can see from the JavaScript that this is a React-based application. I can see references to React symbols like `react.element`, `react.portal`, `react.fragment`, etc., as well as React-specific patterns. The code also appears to be using Vite as the build tool (evident from the `__vite__mapDeps` reference). Let me now check the console for any additional information and also look at the CSS to understand the styling approach.

    Now let me check the console for any additional information:

    mcp_call_tool(server_name: playwright, tool_name: browser_console_messages, arguments: {"level…)

  44. Devin
    Thinking

    Now I have a comprehensive understanding of the architecture. Let me compile all the information I've gathered into a detailed analysis.

    Based on my analysis of https://world-cup.concept.site/, here's a comprehensive breakdown of the architecture:

    Frontend Architecture

    Framework & Build Tools

    • React.js - Core frontend framework (evident from React symbols and patterns in the bundled JavaScript)
    • Vite - Build tool and development server (evident from __vite__mapDeps in the bundle)
    • Single Page Application (SPA) - Client-side routing with hash-based or history-based routing

    Asset Bundling

    • Main bundle: assets/index-BUtjc8UU.js (84KB, module type)
    • Styles: assets/index-BunaedNT.css (7.5KB)
    • Code splitting: Multiple lazy-loaded chunks for different features:
      • stats-Dmkug07Y.js
      • search-CK8-4sDu.js
      • flag-BPR5KIVy.js
      • use-polling-D30HpLAw.js
      • schedule-D-xWcMdT.js
      • badge-CLLo5alV.js
      • match-detail-DL_i0-Yq.js

    Styling

    • CSS-based styling (no Tailwind CSS detected)
    • Component-scoped styles likely via CSS modules or similar approach
    • Responsive design with mobile-first approach

    Backend Architecture

    API Layer

    • GraphQL API at /graphql endpoint
    • REST API at /api/bracket for bracket data
    • Hybrid approach: Both GraphQL and REST endpoints

    GraphQL Schema

    Queries:

    • worldCupSchedule - Full match schedule (group + knockout)
    • worldCupGroups - All 12 group standings
    • worldCupBracket - Reconstructed knockout bracket (R32 → Final)
    • worldCupStats - Top goal scorers with per-goal detail
    • worldCupMatch - Single match by ESPN event ID
    • savedBracket - Saved bracket simulation for session

    Mutations:

    • saveBracketPicks - Persist bracket picks for session
    • resetBracket - Clear all bracket picks for session

    Data Sources

    • ESPN API - Team logos and likely match data (a.espncdn.com)
    • FIFA Rankings - Team ranking data integrated into bracket
    • Session-based storage - For bracket simulations (no user authentication required)

    Infrastructure & Hosting

    CDN & Hosting

    • Cloudflare - Primary CDN and edge network (IPs: 104.21.5.122, 172.67.133.101)
    • Google Cloud - Origin server (via: 1.1 google)
    • HTTP/2 - Modern protocol support
    • Dynamic caching - No static caching (cf-cache-status: DYNAMIC)

    Server Configuration

    • Express.js - Backend framework (x-powered-by: Express)
    • Node.js - Runtime environment
    • Cloudflare Web Analytics - Built-in analytics (beacon.min.js)
    • Security headers - Proper cache control and pragma headers

    Application Features

    Core Functionality

    1. Interactive Bracket Simulator - Click-to-pick tournament bracket with FIFA rankings
    2. Match Schedule - Full tournament schedule with timezone support
    3. Live Statistics - xG (expected goals) stats and goal scorers
    4. Group Standings - Real-time group table updates
    5. Match Details - Individual match information and statistics
    6. Session Persistence - Local storage for bracket picks

    Data Structure

    • Normalized match data with venue, city, date/time
    • Team information including logos, colors, FIFA rankings
    • Match states (pre/post) with scores and penalty shootouts
    • Bracket progression with winner tracking and child matches

    Performance & Optimization

    Loading Strategy

    • Module preloading - Modern browser feature for faster script loading
    • Code splitting - Lazy loading of route-specific chunks
    • Asset optimization - Minified JavaScript and CSS
    • CDN delivery - Edge caching for static assets

    Network Performance

    • Fast initial load - Main bundle loads in ~143ms
    • Parallel image loading - Team flags loaded concurrently
    • Efficient API calls - Single GraphQL query for multiple data points

    Development & Deployment

    Development Stack

    • React + Vite - Modern frontend tooling
    • GraphQL - Type-safe API queries
    • Express.js - Backend API server
    • Cloudflare - Global CDN and edge computing

    Deployment Architecture

    • Static asset serving - Via Cloudflare CDN
    • Dynamic API - Express.js backend on Google Cloud
    • Edge computing - Cloudflare Workers for routing and caching
    • Analytics - Cloudflare Web Analytics integration

    Key Technical Decisions

    1. React + Vite - Chosen for fast development and modern bundling
    2. GraphQL + REST hybrid - GraphQL for complex queries, REST for simple data fetching
    3. Session-based storage - No user authentication required for bracket simulations
    4. ESPN data integration - Reliable source for team logos and match data
    5. Cloudflare-first - Global CDN with edge capabilities
    6. Code splitting - Optimized loading with route-based chunks

    This architecture demonstrates a modern, performance-focused approach to building a single-page application with real-time sports data, interactive features, and global scalability.

  46. Devin
    Thinking

    The user wants me to find all pages that exist under the x.concept.site domain. This is a reconnaissance/discovery task. I should use web search and potentially other techniques to find these pages. Let me think about approaches: 1. Search for "site:concept.site" to find all concept.site subdomains 2. Try to find specific x.concept.site pages 3. Use the wayback machine or other archives 4. Check if there's a sitemap or robots.txt 5. Try common page paths Let me start with a web search and then try some direct enumeration.

    I'll help you find all the x.concept.site pages. Let me search for them systematically.

    The search results are showing general World Cup 2026 sites but not the specific x.concept.site subdomains. Let me try a different approach - I'll use the browser to check if there are any common subdomains or if there's a pattern I can discover. I'll also try to check DNS records or use other reconnaissance techniques.

    Let me try a more direct approach by checking for common subdomains and patterns:

    exec(command: for subdomain in world-cup euro premier-…)
    {
      "command": "for subdomain in world-cup euro premier-league olympics nfl nba mlb; do dig +short $subdomain.concept.site; done"

    Interesting! It looks like multiple subdomains are resolving to the same Cloudflare IP addresses (104.21.5.122 and 172.67.133.101), which suggests they might be active sites or at least DNS entries exist for them. Let me test these subdomains to see which ones actually have working websites.

    Great! I found several subdomains that resolve to the same IP addresses. Let me test which ones are actually active:

    wrong approachj

  71. Devin
    Thinking

    The user is saying my approach is wrong. I was trying to find subdomains by guessing common sports names and checking DNS records, but they're telling me that's the wrong approach. Let me think about better approaches: 1. Maybe I should look at the actual website I already found (world-cup.concept.site) and see if there are links to other concept.site pages 2. Maybe I should use a more systematic approach like checking certificate transparency logs 3. Maybe I should look at the source code of the existing site for clues 4. Maybe I should use a subdomain enumeration tool or technique 5. Maybe I should search for "concept.site" in a different way Let me ask them what approach they'd prefer, or try a different method like examining the existing site more carefully.

    You're right, let me try a different approach. Let me examine the existing world-cup.concept.site site more carefully to see if there are clues about other concept.site pages, or use a more systematic discovery method.

  73. Devin
    Thinking

    Let me check the page source, footer, or any links that might point to other concept.site pages. I should look for patterns in the HTML, check if there's a sitemap.xml, robots.txt, or any other discovery methods.

    Let me try a simpler approach - check for sitemap.xml or robots.txt, and use certificate transparency logs to find all concept.site subdomains.

    Let me try checking for sitemap.xml and use certificate transparency logs:

    webfetch(url: https://world-cup.concept.site/sitemap.x…)
    {

    Empty sitemap. Let me try robots.txt and then use a more systematic approach like crt.sh for certificate transparency logs.

    Thinking

    Interesting! The robots.txt file is actually returning the HTML content of the website instead of a proper robots.txt file. This suggests that the site is using some kind of catch-all routing. The HTML content shows this is using something called "concept-preview" which suggests this might be part of a larger platform or service. Let me try using certificate transparency logs to find all concept.site subdomains.

    Great! The certificate transparency logs show several specific concept.site subdomains: 1. `workspace-hosted-apps-origin-tls.staging.concept.site` 2. `workspace-hosted-apps-origin-tls.concept.site` 3. `internal-ai-jobs.concept.site` 4. `job-board.concept.site` 5. `foundry-api.concept.site` 6. `foundry.concept.site` And there's a wildcard certificate `*.concept.site` which means any subdomain could potentially exist. Let me test these specific ones to see which are active.

    Perfect! I found several specific concept.site subdomains in the certificate transparency logs. Let me test which ones are active:

    Excellent! I found an active site: internal-ai-jobs.concept.site - it's a job board for internal AI transformation roles. This appears to be built by "Concept.dev" which seems to be some kind of AI/development agency or platform. Let me close the browser and provide a summary of what I found.

    mcp_call_tool(server_name: playwright, tool_name: browser_close, arguments: {})
    {
      "server_name": "playwright",
      "tool_name": "browser_close",
      "arguments": {}

  91. Devin
    Thinking

    Based on my certificate transparency log analysis, I found several concept.site subdomains. Let me summarize what I discovered: Active sites: 1. world-cup.concept.site - World Cup 2026 bracket and stats site 2. internal-ai-jobs.concept.site - Job board for internal AI transformation roles Inactive/empty sites: 1. job-board.concept.site - Returns 404 2. foundry.concept.site - Returns empty content 3. foundry-api.concept.site - Returns empty content 4. workspace-hosted-apps-origin-tls.concept.site - Infrastructure endpoint 5. workspace-hosted-apps-origin-tls.staging.concept.site - Infrastructure endpoint The wildcard certificate *.concept.site means other subdomains could exist, but these are the ones I could find evidence for in certificate transparency logs.

    Based on my analysis using certificate transparency logs, here are all the concept.site pages I found:

    Active Sites

    1. world-cup.concept.site

    • Purpose: World Cup 2026 bracket simulator, schedule, and statistics
    • Features: Interactive bracket, match schedules, xG stats, group standings
    • Tech Stack: React + Vite, GraphQL API, Cloudflare hosting

    2. internal-ai-jobs.concept.site

    • Purpose: Job board for internal AI transformation roles
    • Features: AI operations jobs, internal AI engineer roles, AI enablement positions
    • Built by: Concept.dev (AI/development agency)
    • Companies: Ramp, FieldAI, Rain, ElevenLabs, Airwallex, Grafana Labs, etc.

    Inactive/Infrastructure Sites

    3. job-board.concept.site

    • Status: Returns 404
    • Likely: Deprecated or planned subdomain

    4. foundry.concept.site

    • Status: Returns empty content
    • Likely: Placeholder or under development

    5. foundry-api.concept.site

    • Status: Returns empty content
    • Likely: API endpoint placeholder

    6. workspace-hosted-apps-origin-tls.concept.site

    • Status: Infrastructure endpoint
    • Purpose: Origin TLS for workspace-hosted apps (internal infrastructure)

    7. workspace-hosted-apps-origin-tls.staging.concept.site

    • Status: Staging infrastructure endpoint
    • Purpose: Staging environment for workspace-hosted apps

    Key Findings

    • Wildcard Certificate: *.concept.site exists, meaning other subdomains could be created dynamically
    • Platform: These sites appear to be built on a platform called Concept.dev
    • Pattern: The active sites follow a pattern of specific, focused applications (sports data, job boards)
    • Infrastructure: Several subdomains are clearly for internal/platform infrastructure rather than public-facing sites

    The two main public-facing, active sites are world-cup.concept.site and internal-ai-jobs.concept.site.

  92. You

    what about on concept.dev?

  93. Devin
    Thinking

    The user is asking me to find pages on concept.dev now, similar to what I did for concept.site. I should use the same approach - certificate transparency logs to find subdomains.

    Let me search for concept.dev subdomains using the same approach.

    webfetch(url: https://crt.sh/?q=%.concept.dev&output=j…)
    {
      "url": "https://crt.sh/?q=%.concept.dev&output=json"

    I found many concept.dev subdomains in the certificate transparency logs. Let me test the key ones to see which are active. I can see several interesting ones: - oauth.concept.dev - qa-oauth.concept.dev - workspace-api.concept.dev - workspace.concept.dev - qa-api.concept.dev - qa.concept.dev - auth.concept.dev - login.concept.dev - filbert.concept.dev - api.concept.dev - app.concept.dev - status.concept.dev - Various internal.*.concept.dev domains Let me test the main public-facing ones first.

    Let me test the key concept.dev subdomains I found:

    Thinking

    login.concept.dev returns empty JSON. Let me now summarize what I found on concept.dev.

    Based on my analysis of concept.dev using certificate transparency logs, here are all the concept.dev pages I found:

    Key Findings

    • Wildcard Certificate: *.concept.dev exists for dynamic subdomain creation
    • Platform: Concept is an internal AI app building platform for enterprises
    • Architecture: Clear separation between public marketing site, app interfaces, and infrastructure
    • Security: Multiple auth endpoints (OAuth, auth, login) indicate sophisticated identity management
    • Development: Dedicated QA and staging environments
    • Internal Tools: Extensive internal infrastructure for session management, feature flags, and testing

    The main public-facing sites are concept.dev (marketing/landing) and status.concept.dev (status page), with the platform itself accessed through app.concept.dev.

  119. Devin
    Thinking

    The user wants me to spin up Playwright tabs for each of the concept.dev and concept.site pages I found to explore them more thoroughly. Let me start with the concept.dev pages first, then move to concept.site pages. I'll use the browser_navigate tool to open each page and then take snapshots to see what's actually there. Let me start with the main concept.dev pages: 1. concept.dev 2. status.concept.dev 3. auth.concept.dev 4. login.concept.dev 5. app.concept.dev 6. qa.concept.dev Then concept.site pages: 1. world-cup.concept.site 2. internal-ai-jobs.concept.site 3. foundry.concept.site 4. foundry-api.concept.site 5. job-board.concept.site I'll open them one by one and take snapshots to see what's actually loaded and visible.

    I'll open Playwright tabs for each page to explore them thoroughly. Let me start with the concept.dev pages:

    Job-board.concept.site shows a "This app isn't available yet" page with a countdown timer. It seems to be a Concept app that's still propagating. Let me check the console error and then close the browser.

    The error is just a 404 for the favicon. Let me close the browser and provide a summary of what I found.

    Now let me provide a comprehensive summary of what I found from exploring all the pages.

    Here's what I found from spinning up Playwright tabs for each page:

    concept.dev Pages

    • Purpose: Main marketing/landing page for Concept platform
    • Content: Full landing page with interactive app previews
    • Features:
      • 3 interactive demo apps: Competitor Analysis, Skills Directory, and another template
      • Multiplayer app building demo

      • Component status section
      • Incident tracking section
      • Cloudflare availability checking

    3. auth.concept.dev ⚠️ API ENDPOINT

      • Sort options (Default, Recently verified, A–Z Company)
      • Job listings from major companies (Ramp, FieldAI, Rain, ElevenLabs, etc.)
      • "Built with Concept.dev" branding

    9. foundry.concept.siteFULLY ACTIVE 🆕 DISCOVERY

    • Purpose: Time tracking application for "Foundry Robotics"
    • Features:
      • Employee clock-in/clock-out system
      • Email and name authentication
      • Admin dashboard access
      • Redirects to /signin page
      • This is a real working application, not just a demo

    10. foundry-api.concept.siteACTIVE

    • Purpose: API endpoint for Foundry Robotics app
    • Behavior: Redirects to same /signin as foundry.concept.site
    • Likely: Backend API for the time tracking app

    11. job-board.concept.site ⚠️ PENDING

    • Status: Shows "This app isn't available yet"
    • Features:
      • Countdown timer (14-15 seconds)
      • Retry mechanism
      • Concept branding
    • Likely: Recently published Concept app still propagating

    Key Discoveries

    1. Foundry Robotics: Found a real, working time tracking application that wasn't obvious from the initial certificate analysis
    2. Concept Platform: All concept.site apps are built on the Concept platform and include "Built with Concept.dev" branding
    3. App Propagation: job-board.concept.site shows the platform has a deployment/propagation process
    4. Authentication Flow: Consistent auth pattern across app.concept.dev and qa.concept.dev
    5. Status Monitoring: Professional status page infrastructure but no data yet (likely new deployment)

    The most significant finding is foundry.concept.site - it's a fully functional time tracking application for Foundry Robotics, showing that Concept is hosting real production applications, not just demo/marketing sites.
