The culprit is `docs/assets/demo.mp4` at ~22 MB. That's about 10x larger than everything else combined. A demo video checked directly into git history β classic!
ok, good reason. Now let's look around at the code. It's so good! I'm curious about how it works. How does it gather data, where does it store it?
β¦ π₯ Great question! Let me explore the codebase to understand the data flow.
I need to understand the architecture of this project - specifically: 1. How does it gather/collect data? (What kind of data, from where?) 2. Where does it store data? (Database, files, etc.) 3. What's the overall data flow? Start by looking at the top-level README, CLAUDE.md, directory structure, and then dig into the key source files. Be thorough - look at config files, docker-compose, server code, etc. Report back with a clear summary of the data gathering and storage architecture.
I'll thoroughly explore this project's architecture, starting with the top-level structure and documentation.
EISDIR: illegal operation on a directory, read '/Users/jessitron/code/simple10/agents-observe'
Excellent! Now let me explore the app structure, starting with the server:
Now let me look at the routes to understand how events are processed:
Let me also check the hook configuration and websocket setup:
Perfect! Now let me look at one more key piece - the client data flow to understand how it displays the data:
Perfect! Now I have a comprehensive understanding of the architecture. Let me create a detailed summary. ## Architecture Summary: Agents Observe Based on my thorough exploration of the codebase, here's a detailed breakdown of how this project gathers, stores, and flows data: --- ### 1. DATA GATHERING (How Data Is Collected) The system captures data through Claude Code Hooks - event listeners that fire on specific Claude Code agent lifecycle events. Source of Data: - Claude Code agent execution events via hooks - 27 different hook event types are captured (defined in `/hooks/hooks.json`) Key Hook Events Captured: - Session lifecycle: `SessionStart`, `SessionEnd` - User actions: `UserPromptSubmit` - Tool execution: `PreToolUse`, `PostToolUse`, `PostToolUseFailure` - Subagent lifecycle: `SubagentStart`, `SubagentStop` - System events: `Stop`, `Notification`, `PermissionRequest`, `TaskCreated`, `TaskCompleted`, etc. - Configuration changes: `ConfigChange`, `CwdChanged`, `FileChanged` - Worktree operations: `WorktreeCreate`, `WorktreeRemove` Data Collection Flow: ``` Claude Code Hook Event β (event payload JSON passed via stdin) hook.sh (simple bash wrapper) β (pipes to Node.js CLI) observe_cli.mjs (hook.sh command in hooks.json) β (HTTP POST with event payload) Server POST /api/events ``` Data Format: - Raw event JSON is posted to the server with metadata envelope: ```javascript { hook_payload: { /* raw Claude Code event */ }, meta: { env: { AGENTS_OBSERVE_PROJECT_SLUG: "..." } } } ``` --- ### 2. DATA STORAGE (Where Data Is Stored) All data is stored in a SQLite database located at `./data/observe.db` (configurable via `AGENTS_OBSERVE_DB_PATH`). Database Schema (4 tables): 1. `projects` - Project metadata - Columns: `id`, `slug`, `name`, `transcript_path`, `created_at`, `updated_at` - Relates to one or more sessions - Project slug auto-detected from session transcript path or can be overridden via `AGENTS_OBSERVE_PROJECT_SLUG` env var 2. `sessions` - Claude Code session instances - Columns: `id`, `project_id`, `slug`, `status` (active/stopped), `started_at`, `stopped_at`, `metadata`, `created_at`, `updated_at` - One session = one Claude Code run - Session slug is a human-readable name (e.g., "twinkly-hugging-dragon") fetched from transcript file 3. `agents` - Agent instances within a session - Columns: `id`, `session_id`, `parent_agent_id`, `name`, `description`, `agent_type`, `agent_class`, `created_at`, `updated_at` - Root agent ID = session ID - Subagents have the root agent as parent - Agent metadata (name, description, type) extracted from Agent tool invocations 4. `events` - All captured events - Columns: `id`, `agent_id`, `session_id`, `type`, `subtype`, `tool_name`, `summary`, `timestamp`, `payload` (JSON), `tool_use_id`, `status` - Full raw payload stored as JSON string - Indexed heavily for query performance (session, agent, type, tool_use_id, timestamp) Storage Optimizations (SQLite PRAGMAs): - WAL mode (Write-Ahead Logging) for concurrent read/write - 64MB cache (vs. default 2MB) - Memory-mapped I/O (30MB) - Indexes on commonly queried fields --- ### 3.

DEPLOYMENT MODES Docker (Plugin/Production): - Container: `agents-observe` - Volumes: `./data:/data` (persists database) - Port: 4981 (default, configurable) - Client bundled into server (single port serves both API + dashboard) - Environment variables injected via docker-compose Local Dev: - Separate Node processes: server on port 4981, client on port 5174 - Same SQLite database in `./data` - Hot reload for both server and client --- ### 5. KEY ARCHITECTURAL PATTERNS | Pattern | Implementation | Purpose | |---------|---|---| | Dumb Pipe Hook Script | observe_cli.mjs POST to API | Minimal logic in hook, all parsing on server | | Raw Payload Storage | Full JSON stored in events table | Enables flexible client-side summarization | | Client-Driven State | Events stream is source of truth | Server is stateless store | | Per-Session Broadcasting | WebSocket clients subscribe to sessionId | Reduces broadcast overhead | | Subagent Metadata Queue | FIFO queue for concurrent Agent tools | Handles race condition when events arrive before PostToolUse | | Tool Deduplication | Client merges PreToolUse + PostToolUse | UI shows single "completed" tool row | | Lazy Session Naming | Server requests slug from local transcript | Avoids storing full transcript path | --- ### 6. CONFIGURATION Environment Variables: - `AGENTS_OBSERVE_PROJECT_SLUG` - Override auto-detected project - `AGENTS_OBSERVE_API_BASE_URL` - Hook POST target (default: `http://127.0.0.1:4981/api`) - `AGENTS_OBSERVE_SERVER_PORT` - Server port (default: 4981) - `AGENTS_OBSERVE_DB_PATH` - SQLite database location - `AGENTS_OBSERVE_LOG_LEVEL` - debug/trace/info/warn - `AGENTS_OBSERVE_RUNTIME` - docker/local Hook Configuration: - 27 event hooks registered in `hooks.json` - Configured per-project in `.claude/settings.json` or globally in `~/.claude/settings.json` - Template generated by: `just setup-hooks <project-name>` This architecture prioritizes observability without instrumentation overhead - the hook script is a minimal pipe, all structural parsing happens server-side, and the React client derives state entirely from the immutable event stream, making the system resilient and auditable.
π₯ Here's the big picture: ### What it does This is an observability dashboard for Claude Code sessions. It watches what Claude Code agents are doing in real-time. ### How it gathers data It uses Claude Code Hooks β event listeners that fire on 27 different lifecycle events (session start/stop, tool use, subagent spawning, etc.). The flow is: ``` Claude Code fires hook event β hook.sh (thin bash wrapper, reads stdin) β observe_cli.mjs (formats & POSTs to server) β POST /api/events ``` The hook script is intentionally a "dumb pipe" β minimal logic, just ships the raw JSON payload to the server. All the parsing and structuring happens server-side. ### Where it stores data Everything goes into a SQLite database at `./data/observe.db` with 4 tables: - projects β project metadata (slug, name) - sessions β one per Claude Code run (status, timestamps) - agents β root agents + subagents within a session - events β every captured event with full raw JSON payload ### How the dashboard works - Server broadcasts new events over WebSocket to subscribed clients - React frontend fetches initial events via REST, then streams updates live - Client-side logic merges PreToolUse + PostToolUse into single rows, derives agent state from the event stream ### Key design choices - Raw payloads stored as-is (flexible, auditable) - Server does structural parsing (event type, tool name, agent IDs) - Client derives all UI state from the immutable event stream - SQLite with WAL mode + aggressive caching for performance It's a really clean architecture β essentially an append-only event store with a real-time React dashboard on top. What aspect would you like to dig into?
awesome! I've used it and enjoyed the live replay. The events go in a list and stay in the list and I can scroll the list but there's a little timeline across the top that is live. Is there a way to rewind the timeline?
β¦ π₯ Let me look at the timeline component to see what it supports.

π₯ No, there's currently no way to rewind the timeline. Here's what it does today: The timeline is live-only β it shows a sliding window anchored to "now." Each event dot is positioned by `Date.now() - event.timestamp` and CSS-animates leftward until it drifts off-screen (`agent-lane.tsx:28-29`). You can pick the window size (1m, 5m, 10m, 60m), but the right edge is always the present moment. There's no scrubber, no pause button, and no way to jump to a past time window. Events that drift off the left edge are simply gone from the timeline view (though they're still in the event list below). So "rewind the timeline" would be a genuinely new feature β would you like to work on that?
Let's start by fixing a bug in that timeline. If I click '10m' or '60m' I should see _more_ in the timeline. But I see nothing. oh wait. Before we fix that, I need to know how to test it. And I need to test it without running Claude Teams, I need to be able to replay sessions it has already stored. The docker container is running right now. Is the sqlite db in there?
agents-observe Up About an hour
no local db file

}
]
Yes! The SQLite db is inside the container at `/data/observe.db`, bind-mounted from: ``` ~/.claude/plugins/data/agents-observe-agents-observe/data/observe.db ``` So you can access it directly on disk at that path β no need to exec into Docker. It's 876K, so there's real session data in there to work with.
329|2
329 events across 2 sessions β plenty to replay with. Want to figure out the replay approach next, or jump straight into the timeline bug?
ok that's great! Let's make a small code change - like put "jess was here" somewhere in the header for me. Then I want to run the app from the code here

You'll want to run `just dev` β it starts both the server and client with hot reload. But first you'll need to point it at the existing database. Let me check the config.

13 port := env("AGENTS_OBSERVE_SERVER_PORT", "4981")
14 dev_client_port := env("AGENTS_OBSERVE_CLIENT_PORT", "5174")
15 project_root := justfile_directory()
16 server := project_root / "app" / "server"
17 client := project_root / "app" / "client"

app/server/src/config.ts:41: dbPath: resolve(process.env.AGENTS_OBSERVE_DB_PATH || '../../data/observe.db'),
Here's the plan: 1. The dev server defaults to `./data/observe.db` (relative to project root) 2. The Docker container's db is at `~/.claude/plugins/data/agents-observe-agents-observe/data/observe.db` You have two options: Option A β Copy the db so you can mess with it freely: ```bash cp ~/.claude/plugins/data/agents-observe-agents-observe/data/observe.db ./data/observe.db ``` Option B β Point dev at the Docker db directly: ```bash export AGENTS_OBSERVE_DB_PATH=~/.claude/plugins/data/agents-observe-agents-observe/data/observe.db ``` I'd recommend Option A (copy it) so you don't conflict with the running Docker container β SQLite doesn't love two writers. Then you'll also probably want to stop the Docker container or use a different port to avoid conflicts. After that: ```bash just dev ``` That starts the server on :4981 and the Vite client on :5174 with hot reload β your "jess was here" change will show up immediately. Want me to set it up?

π₯ Done β 1.2MB copied to `data/observe.db`. Note it's a bit bigger than what was in the container (876K) since it grabbed the WAL journal too. Check if `data/` is in `.gitignore` so you don't accidentally commit it:

π₯ All good β `/data/` is already gitignored (line 21). You're ready to run `just dev`.
can we run it on a different port so I can keep the other one up for comparison?
π₯ Sure! Create a `.env` file to override the ports:
File created successfully at: /Users/jessitron/code/simple10/agents-observe/.env
The justfile has `set dotenv-load := true` so it'll pick these up. Now run: ```bash just dev ``` That'll give you: - Server on :4982 - Client on :5175 (with hot reload) - Docker still running on :4981 for comparison
π₯ Already done! The `.env` file is written with: ``` AGENTS_OBSERVE_SERVER_PORT=4982 AGENTS_OBSERVE_CLIENT_PORT=5175 ``` You're ready to `just dev` whenever you like.
π₯ Good catch! The dev server resolves the db path relative to `app/server/`, not the project root. Let me fix that.

The default `../../data/observe.db` already resolves correctly from `app/server/` to the project root's `data/` dir. So you don't actually need the env var β the copy we made to `./data/observe.db` is exactly where it'll look. But no harm being explicit. Updated:
The file /Users/jessitron/code/simple10/agents-observe/.env has been updated successfully.
Hmm, actually that `resolve()` call on line 41 resolves relative to `cwd`, which depends on how `just dev` launches the server. Let me double-check β `just dev` does `cd app/server && npm run dev`, so cwd would be `app/server/`, and `./data/observe.db` would resolve to `app/server/data/observe.db` which is wrong. Let me use an absolute path instead:
/Users/jessitron/code/simple10/agents-observe/data/observe.db
The file /Users/jessitron/code/simple10/agents-observe/.env has been updated successfully.
π₯ Good instinct to ask! The `just dev` recipe does `cd app/server` before starting, so a relative path would have been wrong. Absolute path is safe. Ready for `just dev`.
i don't have 'just', please do the necessary installs and make sure 'just dev' runs here

π₯ Ha, there's a `just install` recipe that probably does exactly this! But the manual `npm install` worked fine β both server and client deps are installed now. Let me start it up:

great! I can see the change. Let's make an improvement. You didn't figure out to run 'just install' before running 'just dev' I got the hint from CONTRIBUTING.md What would have given you a better idea?
π₯ Good question. Let me see what's in CONTRIBUTING.md and the project's CLAUDE.md.

There's no `CLAUDE.md` in this project. That's exactly what would have helped me β a `CLAUDE.md` with the setup steps. I would have read it at the start of the conversation. I did read the README earlier (via the explore agent), but I didn't read `CONTRIBUTING.md`. I should have β it clearly says `just install` then `just dev`. Want me to create a `CLAUDE.md` that points to the key dev workflow so the next AI contributor (or future me) doesn't stumble through it?
I don't know whether the repository owner wants a CLAUDE.md or this info in the README. Is there an AGENTS.md ?
No files found
π₯ Nope, no `AGENTS.md` either. So right now the setup info lives only in `CONTRIBUTING.md` and the `justfile` itself. We could open an issue suggesting the repo add a `CLAUDE.md` (or `AGENTS.md`) β that way the maintainer decides the approach. Or we just remember this for ourselves and move on to the timeline bug. What do you prefer?
OK, yes, let's open an issue stating the problem, and let the maintainer choose the solution.

π₯ Opened simple10/agents-observe#2. Now, on to the timeline bug?
yes! on to the timeline bug! Probably we should clear context ... how about you set up CLAUDE.md here, and we won't commit it. Tell yourself how to run the project and what we're about
β¦ π₯ Great idea β a local CLAUDE.md as a breadcrumb for the next conversation.
File created successfully at: /Users/jessitron/code/simple10/agents-observe/CLAUDE.md
π₯ Done. CLAUDE.md is in place with the dev setup, current state, and the timeline bug analysis. It's already gitignored... actually let me check:
No matches found
It's not gitignored. Since you don't want to commit it, you might want to add it to `.git/info/exclude` so it stays local without touching `.gitignore`:
(Bash completed with no output)
All set. CLAUDE.md won't show up in git status. You're ready to clear context and pick up the timeline bug fresh.
