## 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 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)

)"
```
### 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":"cloudflare-docs"},{"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"},{"name":"cloudflare-observability"},{"name":"cloudflare-bindings"},{"name":"cloudflare"},{"name":"playwright"},{"name":"cloudflare-builds"}]}
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.

theres an issue where in some chats the last assistant message is not being surfaced to the database, can you diagnose and do rca?
I'm diving into the codebase to trace how chat persistence works.
Let me explore the codebase to understand how chats and messages are persisted.

</file-view>I see the issue now — the daemon syncs by checking for rows where row_id exceeds the last synced value, but the CLI is updating existing message_node rows in place rather than inserting new ones. This means updates to those rows get skipped during sync, which is why the final assistant message doesn't surface. Let me verify this by checking the actual SQLite database to see if rows are being updated rather than inserted, and comparing the chat_message content between SQLite and Supabase to confirm the mismatch.I'm going to trace the sync pipeline from the Devin CLI SQLite DB through the daemon to Supabase and the Next.js app to find where messages are getting lost.

I'm thinking through how the message_nodes table handles streaming updates — the unique constraint on (session_id, node_id) means the CLI either updates the same row as content streams in, or uses INSERT OR REPLACE which would create a new row_id each time since AUTOINCREMENT is involved. This points to two potential issues: either rows are being updated in place after sync, causing the daemon's watermark query to miss those updates and leave stale content in Supabase, or the upsert logic is creating duplicate rows with different row_ids when the CLI uses INSERT OR REPLACE, leading to deduplication problems downstream. The reported symptom is the last assistant message not showing up, so I should verify whether the daemon is actually running and compare what's in SQLite versus what made it to Supabase for a given session.

The daemon isn't running, and while the state file shows we're near SQLite's max capacity, that's just indicating the process stopped—not necessarily related to the reported issue about missing assistant messages in some chats. I need to compare what's stored in Supabase versus SQLite for each session to see if there's a discrepancy in the max node IDs, which means pulling the Supabase credentials from the environment file and querying it. There's also a hypothesis about whether updates are happening in-place that I should investigate. I need to write a diagnostic script to connect to Supabase and compare the data directly—checking whether the content actually differs between SQLite and Supabase for the same row IDs, and whether there's a mismatch between the max node_id in Supabase versus where the watermark has advanced.The daemon is stopped and there's a watermark mismatch between the state file and SQLite. I'll compare Supabase against SQLite to identify the actual discrepancy in the affected chats.

I'm writing a diagnostic script to compare the last assistant message per session between SQLite and Supabase, focusing on sessions synced before watermark 24017 since anything after that is expected to be missing. My hypothesis is that the Devin CLI writes an assistant message while streaming, then updates the same row using an upsert pattern based on the unique constraint on session_id and node_id.I'll now compare the synced rows between Supabase and SQLite to identify where the data diverges.

The row counts match up to the watermark with no in-place updates, so the data itself looks fine. The missing rows from 24018 onward suggest the daemon might not be running currently, but that would affect entire recent sessions rather than just the last assistant message in specific chats. This points to either a daemon availability issue or a race condition. Actually, I think I've found it — the real culprit is likely the UNIQUE constraint on (session_id, node_id) combined with INSERT OR REPLACE in the CLI. When finalizing an assistant message, the CLI replaces the row by deleting the old one and inserting a new one with a higher row_id. But in Supabase, the upsert only tracks by row_id, so the old row never gets deleted — both the stale old row and the new row persist. Then when data.ts dedupes messages by message_id, if both rows have the same node_id and message_id but different row_ids, the ordering becomes ambiguous and the last-wins logic could pick the stale one instead of the fresh one. But wait, my diff script checked rows in Supabase against SQLite by row_id up to the watermark and found missingLocal=0, meaning no rows were missing locally. If REPLACE was happening, the old row_ids would be gone from SQLite but still in Supabase, which would show up as missingLocal > 0. So that's not it. The data actually syncs faithfully up to the watermark, so the real issue might be row_id gaps — SQLite shows max row_id of 24827 but only 23247 rows, leaving 770 gaps. AUTOINCREMENT shouldn't create gaps unless rows are deleted or transactions roll back, which means the CLI is actively deleting rows. Those deletes don't propagate to Supabase, but my diff found no evidence of that either. The actual race condition I'm seeing: with multiple concurrent CLI sessions writing to the same database, the daemon polls and sets its watermark based on the max committed row_id it observes. But SQLite's write locking and WAL mode serialize commits in order, so row allocation and commit happen atomically — a row allocated later can't commit before an earlier one, so out-of-order commits shouldn't happen. The gaps are likely from deletes or rollbacks happening before the daemon syncs them, or from delete-and-reinsert cycles within the same transaction that the daemon never observes. Since data up to the watermark is perfectly consistent, the real issue is rows beyond it — the daemon probably stopped running. The timestamps suggest it halted around 11:12 UTC, which would explain why recent chat tails are missing. But the user's description of "last assistant message not surfaced" sounds more systematic than just a stopped daemon — it's a specific pattern where everything syncs except the final assistant message, which suggests something about the write ordering or sync sequencing for that particular message type. Looking at the read path, there's a deduplication mechanism keyed by message_id that keeps the last node when duplicates exist, but the schema uses a tree structure with parent_node_id and a main_chain_id per session. The web app fetches all nodes sorted by node_id and dedupes by message_id without respecting the tree structure, which could theoretically surface wrong messages. But that wouldn't explain a missing last message — it would show the wrong one. Since the watermark data is perfectly consistent, any missing message must be beyond the watermark, which points back to daemon stoppage. But the timing correlation is suspicious enough that I should look at actual data to see if there's a pattern I'm missing. Actually, I think I've found it: the CLI streams assistant responses by inserting the node early and updating it in place as chunks arrive. The daemon polls every 2 seconds and syncs the row mid-stream with partial content. Since the watermark is row_id-based, subsequent updates to that same row never get re-synced. The final assistant message of a conversation is most vulnerable because nothing follows it to trigger a new row and force a resync. The reason my diff showed zero mismatches for rows within the watermark is probably because the user ran a bulk sync recently, which would have re-upserted everything and hidden the evidence of mid-stream captures. Now I'm noticing the state file shows last_message_row_id at 24017 but the actual max is 24827 — that's a significant gap. I should test this empirically by monitoring whether rows actually get updated in place. Since this very session I'm running in the CLI is writing to sessions.db, I can watch the "zany-glade" session and sample the same row's content length a few seconds apart to see if it changes, or check whether the newest assistant message rows have grown since my earlier query.The synced rows are byte-for-byte identical between SQLite and Supabase, so the daemon is working correctly. Now I'll check whether the CLI updates rows in place after insertion by observing the live session.

The assistant messages are written to the database only after the step completes, not during streaming, so there's no in-place update issue to worry about. The current message I'm generating hasn't been inserted yet—that happens once this turn finishes. I'm trying to figure out the exact timing of when the database writes occur. The real question is why some chats are missing their last assistant message in Supabase. Since rows up to the watermark match perfectly between SQLite and Supabase, the missing data must be above the watermark, which points to the daemon stopping at 02:20. But I should verify this against the actual data: for sessions fully below the watermark, check if any are missing their final assistant message. If none are, then the root cause is simply that the daemon stopped. There's also a potential race condition in the sessions watermark logic—the daemon re-reads the max activity timestamp after upserting sessions, and if a session's last_activity_at advanced during the network call, the watermark could jump past it, leaving that session's row out of sync until it becomes active again. That would cause stale session metadata, though not missing messages. The message batch fetching looks fine with its 500-item limit and watermark update. But there's another angle I haven't fully explored yet around the daemon's long-lived prepared statements. Let me write a quick query to check for sessions where all rows are below the watermark but the last message is still missing in Supabase, and also characterize the overall message count differences per session to understand the scope of "some chats."I've confirmed that rows are stable once written and the assistant message only inserts when the step completes. Now I'll identify which messages are missing in Supabase for each session.

The missing data starts after watermark 24017, which corresponds to 09:20:17 UTC—the daemon appears to have stopped syncing around that timestamp, with the .sync-state.json modification time suggesting this happened in the local timezone as well. skipped on the next sync. That's the real bug: between the final empty batch and saving state, new rows inserted aren't captured until the next daemon tick. The user's actual symptom though — missing 70+ rows per chat, not just the final message — points back to the daemon simply not running since 02:20. The smaller race condition is theoretically possible but unlikely to explain this scale of data loss. Let me verify the write timing: checking a few idle sessions shows their final nodes are assistant messages already in SQLite, which means writes happen at turn end, not lazily on the next user message. And during active conversations, messages appear every few seconds, so the writes are prompt. This rules out a per-turn buffering issue. The state file timestamp confirms the daemon stopped at 02:20:17 AM local time, and everything written after that — 829 rows across 4 sessions — never made it to Supabase. The daemon likely crashed, the terminal closed, or the laptop slept. I should check if there's a process manager or log file that might explain why it stopped. Now I'm realizing the user said "some chats" are missing their last assistant message. If the daemon has been down since 02:20, then chats active across that boundary would be truncated in Supabase, while older chats would appear complete. But I need to verify whether the session rows themselves synced — if panoramic-bicycle and zany-glade session rows are missing from Supabase, those chats wouldn't even appear in the list. Let me check the sessions table directly. Also, I'm wondering if there was an earlier instance of this before today that got fixed by a later bulk run, or if the user ran bulk at 02:20 and never started the daemon afterward. I should check the shell history to see what commands were actually run, and look for any LaunchAgent or background process that might be keeping the sync running.I found that every missing row occurs after the state-file watermark at 2026-07-08 09:20 UTC. Now I'll check the session rows in Supabase and verify the daemon's expected running state.

The daemon isn't running and there's no LaunchAgent keeping it active. The last sync happened at July 8, 02:20:17 PDT when the state was saved at watermark 24017. Everything up to that point made it to Supabase intact, but anything after that sync is gone. I'm wondering why the user is describing this as missing assistant messages in specific chats rather than seeing it as a broader issue with recent conversations being incomplete. Looking at serious-fisher, the missing nodes start at node 24 (just 9 seconds after the daemon stopped) and continue through 10:22, so chats that were active when the daemon died have their tails cut off while earlier messages remain. For chats that started after the daemon stopped like zany-glade and panoramic-bicycle, the entire conversation is missing because the session rows themselves never synced to Supabase. The user probably doesn't even see those chats in their session list. The daemon likely stopped because the user terminated it manually or closed the terminal. There's also a potential latent bug in how the daemon handles sync errors — when it opens the SQLite database and encounters a network failure, it logs and retries, but I need to trace through what happens if that error persists. There are a couple of other subtle issues worth noting: the bulk sync sets the watermark after the loop, so rows written between the last batch and the watermark call could get skipped. Sessions use second-granularity timestamps for the watermark, so if a session updates twice in the same second, the second update might be missed until the next activity. But the empirical evidence is clear — the root cause is simply that the daemon stopped running at 02:20:17 PDT with no supervision mechanism to restart it. Now I'm verifying the Supabase data: the max row_id of 24017 matches what I'd expect, and the count of synced messages (23247) aligns perfectly with what's in SQLite, confirming nothing was synced after the watermark. The .sync-state.json modification time at 02:20 indicates that's when the sync stopped, whether the daemon crashed or was never running as a background process. I can't easily determine which from the available logs, but either way the sync halted at that moment. For the perceived symptom — the last assistant message missing from a partially-synced session — the session row in Supabase would also be stale, showing an older last_activity timestamp than what's actually in the local database. The user would see messages up to a certain point in the chat, but nothing beyond that. Now I'll clean up the diagnostic scripts I created and prepare the root cause analysis with recommendations for fixes like restarting the daemon or adding proper supervision.The daemon stopped at the watermark time with no supervision. I'll check how the affected chats appear in Supabase and then clean up my diagnostic scripts.

I've identified the exact issue in `serious-fisher`: node 23 contains a synced assistant message with tool calls that appears to be a partial streaming snapshot, while node 24 and beyond never synced at all. This leaves the last visible assistant message in the database truncated, missing its tail or follow-up content. The problem occurs at turn boundaries because the daemon polls every 2 seconds, and it died right at 09:20 when this sync was happening. The daemon likely stopped because the user closed the terminal or pressed Ctrl+C — the `.sync-state.json` modification time matches 09:20 UTC, consistent with a shutdown handler saving state. Without supervision (no launchd agent), any daemon exit silently halts syncing, so recent turns remain incomplete. There's also a latent race condition: nodes 23 and 24 share the same message_id with streaming snapshots, deduped by last-wins logic. If the daemon syncs the partial node 23 but dies before node 24 completes, the UI shows the incomplete version — exactly the "last assistant message not surfaced" symptom the user reported. I'm also checking whether the sync is actually complete while the daemon runs. Looking at the evidence: all rows up to the watermark match perfectly, including plenty of final assistant messages, so the daemon does sync correctly when active. However, there's another latent bug worth flagging — a race in the bulk-mode watermark logic where rows inserted between the final empty fetch and the getMaxRowId() call could be permanently skipped. The watermark is 24017 and all synced rows match exactly up to that point with matching counts, so this particular bug didn't trigger, but it's a real vulnerability given how frequently active sessions write and how long bulk syncs can take. Looking at the state file timing: it was last modified at 02:20 local time, and the watermark shows last_session_activity at 09:20:17 UTC (02:20:17 PDT). The missing rows start at 09:20:19 UTC, just two seconds after that watermark. Checking the workspace file timestamps, the user was actively developing around 02:11–02:20 — likely ran a one-shot bulk sync at 02:20 and never started the daemon, thinking sync was ongoing. The bulk sync completed and exited at 02:20:17, then nothing ran after that. The supabase count of 23247 matches exactly all SQLite rows up to 24017, which is consistent with either bulk or daemon, but the perfect timing and consistency point to bulk running once at 02:20 and the daemon never starting. The fix is straightforward: restart the daemon to resume from watermark 24017 and catch up on everything since 02:20 local. I should present the diagnosis and RCA to the user, then offer to restart the daemon and optionally harden the setup with launchd supervision and race condition fixes. Let me clean up the temporary diagnostic scripts I created first.
The picture is complete. Let me clean up my temporary diagnostic scripts:
{
"command": "cd /Users/root1/devin-chats && rm scripts/diagnose-diff.ts scripts/diagnose-missing.ts && ls scripts/"
}Output from command in shell 46d18c: sync-to-supabase.ts Exit code: 0
I should present the root cause analysis in a straightforward way and then check if they'd like me to provide solutions.
In some chats the final assistant message (and often the whole tail of the conversation) exists in the local SQLite DB but never appears in Supabase.
Sync fidelity is perfect up to the watermark. I compared every row in Supabase against SQLite byte-for-byte: 23,247 rows on both sides up to row_id 24017, 0 mismatches, 0 orphans. So the sync logic itself (row_id-watermark upserts) is not corrupting or skipping data while running.
Everything missing is after one exact timestamp. SQLite now has 24,076+ rows; Supabase stops at row_id 24017. Every missing row across 4 affected sessions (first-scorpio, serious-fisher, panoramic-bicycle, zany-glade) has created_at >= 2026-07-08 09:20:19 UTC — i.e. 02:20 local, which is exactly last_session_activity: 1783502417 in <ref_file file="/Users/root1/devin-chats/.sync-state.json" /> (mtime: Jul 8 02:20).
No sync process is running. ps shows no sync-to-supabase daemon, and there's no launchd agent supervising it.
The symptom reads as "last assistant message missing" because of how partial turns land. E.g. in serious-fisher, node 23 (a streaming snapshot of the assistant turn) was synced at 02:20, but node 24 — the finalized message that supersedes it in the message_id dedupe in <ref_snippet file="/Users/root1/devin-chats/lib/data.ts" lines="99-104" /> — was written 2 seconds later and never synced.
The sync daemon has not been running since 02:20 local. Timeline correlation strongly suggests you ran a sync around 02:20 (env/scripts were being edited 02:11–02:18) — likely sync:bulk, which is one-shot and exits after saving the state file — and the daemon mode was never (re)started. Nothing supervises it, so the failure was silent: chats active at that moment got cut mid-turn, and every chat since is missing its tail.
getMaxRowId() is re-read after the sync loop finishes — rows inserted in that window are skipped forever. Same pattern for sessions in daemon mode (<ref_snippet file="/Users/root1/devin-chats/scripts/sync-to-supabase.ts" lines="160-163" />), where getMaxActivity() is re-read after a slow network upsert. Neither fired this time, but both are permanent-data-loss races.Running npm run sync:daemon will self-heal — the watermark is at 24017, so it will backfill everything missed and catch up.

Two races to fix: 1. Bulk mode (lines 130-133): re-reads getMaxRowId()/getMaxActivity() after sync. Fix: compute max from the data we actually synced. 2. Daemon mode sessions (lines 160-163): re-reads getMaxActivity() after upsert. Fix: use max of synced sessions' last_activity_at. But last_activity_at is a string ISO timestamp in SessionRow... I need to compare. Better: track the max unix timestamp from the raw rows. But getSessions returns converted rows with ISO strings. Actually the sessions query orders by last_activity_at ASC, and filters `WHERE last_activity_at > ?` with unix seconds. The converted SessionRow has ISO string. To compute the new watermark I need the unix seconds. I could either: - Add the raw unix value to SessionRow, or - Just re-query getMaxActivity() BEFORE upsert (snapshot), not after. Actually the cleanest fix that matches "use the fetched batch's own max values": for messages, use `batch[batch.length-1].row_id` (already done correctly in daemon!). For sessions, the issue is we don't have the unix timestamp in the converted row. Wait, let me re-read the daemon code. Lines 170-178 for messages already use `batch[batch.length - 1].row_id` — that's correct! The race I called out is only for sessions in daemon mode (line 163) and bulk mode (lines 131-133). For sessions: the simplest correct fix is to snapshot max BEFORE fetching, or compute from fetched rows. Since SessionRow has ISO string last_activity_at, I can compute max from the batch and convert back to unix seconds. Or, cleaner: change getSessions to also return the raw unix timestamp. But that changes the Supabase row type... Actually SessionRow is the Postgres row type. I shouldn't add fields. Alternative: add a separate method or have getSessions return both. Simplest minimal fix: compute max from the fetched sessions' last_activity_at ISO strings, convert to unix seconds. Actually, even simpler and fully correct: snapshot the current max BEFORE the fetch, then after successful upsert set state to that snapshot. No — that misses rows inserted between snapshot and fetch end... Hmm. The real issue: we fetch `WHERE last_activity_at > state.last_session_activity`, upsert them, then set state to max(activity). If between fetch and upsert-completion a new session is inserted with higher activity, the re-read max would include it, and we'd advance the watermark past a row we never upserted → data loss. Fix: set watermark to max of what we actually fetched (the batch), not max of the table. That's the principled fix. For sessions, I need the max unix timestamp among fetched rows. Let me add a helper that converts the ISO string back to unix seconds, or better, have getSessions return the raw value too. I'll add an internal method that returns raw rows, or just compute from ISO. Actually cleanest: change `getSessions(since)` to return SessionRow[] but also expose the raw last_activity_at unix. Let me just add a parallel method `getSessionsRaw` ... no, too invasive. Simplest: parse the ISO string back. `Math.floor(new Date(iso).getTime() / 1000)`. That's exact since we generated it from unix seconds. Let me do that. For bulk mode: - sessions: use max of fetched sessions' last_activity_at → unix - messages: use last batch's last row_id (already have `since` variable tracking it) Let me rewrite bulkSync and the sessions part of daemonSync.

196| while (batch.length > 0) {Now `getMaxActivity` and `getMaxRowId` are no longer used by the script. They're still part of the SqliteReader interface and used elsewhere? Let me check. They're exported in lib/sqlite.ts. data.ts doesn't use them. Let me check if anything else uses them. Actually they're still useful API surface. I'll leave them in the interface — removing them would be over-reaching. But the daemon no longer uses getMaxActivity. Let me verify the file compiles. Let me run tsc / lint.
Let me verify it compiles and check for unused warnings:
{
"command": "cd /Users/root1/devin-chats && npx tsc --noEmit 2>&1 | head -20; echo \"--- exit: $? ---\""
}Output from command in shell 2dd272: --- exit: 0 --- Exit code: 0
Clean. Now let me check if getMaxActivity/getMaxRowId are now unused — they might trigger lint warnings but tsc passed. Let me check eslint quickly... actually tsc passed clean, that's enough. The interface methods are still public API of the reader, fine to keep. Now install launchd agent. I need to: 1. Create a launchd plist that runs the daemon, auto-starts at login, restarts on crash (KeepAlive). 2. Load it with launchctl. The daemon needs env vars. The script loads .env.local itself via loadEnvFile(), so env vars aren't needed in the plist. Good. Path to tsx: npx tsx. But under launchd, PATH may be minimal. Better to use the absolute path to tsx binary. Let me find it.
{
"command": "which tsx; which node; node --version"
}Output from command in shell db36ce: /opt/homebrew/bin/node v25.9.0 Exit code: 0
{
"command": "ls /Users/root1/devin-chats/node_modules/.bin/tsx && readlink -f /Users/root1/devin-chats/node_modules/.bin/tsx 2>/dev/null || readlink /Users/root1/devin-chats/node_modules/.bin/tsx"
}Output from command in shell ad59cb: /Users/root1/devin-chats/node_modules/.bin/tsx /Users/root1/devin-chats/node_modules/tsx/dist/cli.mjs Exit code: 0
I'll use the local tsx via node to be safe under launchd. The plist will run: `/opt/homebrew/bin/node /Users/root1/devin-chats/node_modules/tsx/dist/cli.mjs scripts/sync-to-supabase.ts daemon --interval 2000` with WorkingDirectory set to the project root. The script loads .env.local itself. First, I need to kill the existing background daemon I started with nohup, since launchd will run its own. Let me find and kill it.
I'll stop the nohup daemon I started earlier (launchd will supervise its own) and install the agent:
{
"command": "pkill -f \"sync-to-supabase.ts daemon\"; sleep 1; ps aux | grep \"sync-to-supabase\" | grep -v grep || echo \"stopped\""
}Output from command in shell 6cacc8: stopped Exit code: 0

All three done. Summary:
The sync daemon hadn't been running since 02:20 local (likely a one-shot sync:bulk that exited). With no supervision, the failure was silent, so every chat active at or after 02:20 lost its tail in Supabase — including finalized assistant messages whose earlier streaming snapshots were synced, producing the "last assistant message missing" symptom. Sync fidelity itself is verified perfect (byte-for-byte, 0 mismatches across 23,247 rows).
MAX() after the network call — closing the window where a concurrent insert would be skipped forever. tsc --noEmit passes..sync-daemon.log.Useful commands going forward:
