Development

Prerequisites

  • Node.js (see .tool-versions for exact version)
  • npm workspaces (comes with Node)

Running the dev server

npm run dev

The dev script automatically picks an available port. Both the server and Expo app run in a Tmux session — see CLAUDE.local.md for system-specific session details.

Running alongside the main checkout

Set PASEO_HOME to isolate state when running a second instance (e.g., in a worktree):

PASEO_HOME=~/.paseo-blue npm run dev
  • PASEO_HOME — path for runtime state (agents, sockets, etc.). Defaults to ~/.paseo.
  • In git worktrees, npm run dev derives a stable home like ~/.paseo-<worktree-name>. On first run, it seeds that home from ~/.paseo by copying agent/project JSON metadata and config.json; actual checkout/worktree directories are not copied.
  • PASEO_DEV_SEED_HOME=/path/to/home npm run dev seeds from a different source home.
  • PASEO_DEV_RESET_HOME=1 npm run dev clears and reseeds the derived worktree home.

Default ports

In the main checkout:

  • Daemon: localhost:6767
  • Expo app: localhost:8081

In worktrees or with npm run dev, ports may differ. Never assume defaults.

Daemon logs

Check $PASEO_HOME/daemon.log for trace-level logs.

Database queries

Run arbitrary SQL against the SQLite database:

# Show table row counts
npm run db:query

# Run any SQL
npm run db:query -- "SELECT agent_id, title, last_status FROM agent_snapshots"
npm run db:query -- "SELECT agent_id, seq, item_kind FROM agent_timeline_rows ORDER BY committed_at DESC LIMIT 10"

# Point at a specific DB directory
npm run db:query -- --db /path/to/db "SELECT ..."

Auto-detects the running dev daemon's database from /tmp/paseo-dev.*, PASEO_HOME, or ~/.paseo/db. Pass either a DB directory or a paseo.sqlite file to --db. The script opens the database directly in read-only mode.

paseo.json service scripts

worktree.setup and worktree.teardown accept either a multiline shell script or an array of commands. Both run sequentially.

{
  "worktree": {
    "setup": "npm ci\ncp \"$PASEO_SOURCE_CHECKOUT_PATH/.env\" .env\nnpm run db:migrate",
    "teardown": "npm run db:drop || true"
  }
}

Every scripts entry with "type": "service" receives these environment variables:

Variable Value
PASEO_SERVICE_<NAME>_URL Proxied daemon URL for a declared peer service. Prefer this for peer discovery; it survives peer restarts.
PASEO_SERVICE_<NAME>_PORT Raw ephemeral port for a declared peer service. Use only as a bypass escape hatch; it can go stale if that peer restarts.
PASEO_URL Self alias for PASEO_SERVICE_<SELF>_URL.
PASEO_PORT Self alias for PASEO_SERVICE_<SELF>_PORT.
HOST Bind host for the service process.

<NAME> is normalized from the script name by uppercasing it, replacing each run of non-A-Z0-9 characters with _, and trimming leading or trailing _. For example, app-server and app.server both normalize to APP_SERVER; that collision fails at spawn time with an actionable error.

PORT is not injected by default. If a framework requires PORT, set it in the command:

{
  "scripts": {
    "web": {
      "type": "service",
      "command": "PORT=$PASEO_PORT npm run dev:web"
    }
  }
}

Build sync gotchas

Relay → Daemon

When changing packages/relay/src/*, rebuild before running the daemon:

npm run build --workspace=@getpaseo/relay

The Node daemon imports @getpaseo/relay from packages/relay/dist/*, not src/*.

Server → CLI

When changing packages/server/src/client/* (especially daemon-client.ts) or shared WS protocol types, rebuild before running CLI commands:

npm run build --workspace=@getpaseo/server

The CLI imports @getpaseo/server via package exports resolving to dist/*. Stale dist means the CLI speaks an old protocol and fails with handshake warnings or timeouts.

CLI reference

Use npm run cli to run the local CLI (instead of the globally installed paseo which points to the main checkout).

npm run cli -- ls -a -g              # List all agents globally
npm run cli -- ls -a -g --json       # Same, as JSON
npm run cli -- inspect <id>          # Show detailed agent info
npm run cli -- logs <id>             # View agent timeline
npm run cli -- daemon status         # Check daemon status

Use --host <host:port> to point the CLI at a different daemon:

npm run cli -- --host localhost:7777 ls -a

Agent state

Agent data lives at:

$PASEO_HOME/agents/{cwd-with-dashes}/{agent-id}.json

Find an agent by ID:

find $PASEO_HOME/agents -name "{agent-id}.json"

Find by content:

rg -l "some title text" $PASEO_HOME/agents/

Provider session files

Get the session ID from the agent JSON (persistence.sessionId), then:

Claude:

~/.claude/projects/{cwd-with-dashes}/{session-id}.jsonl

Codex:

~/.codex/sessions/{YYYY}/{MM}/{DD}/rollout-{timestamp}-{session-id}.jsonl

Testing with Playwright MCP

Use Playwright MCP connecting to Metro at http://localhost:8081 for UI testing.

Do NOT use browser history (back/forward). Always navigate by clicking UI elements or using browser_navigate with the full URL — the app uses client-side routing and browser history breaks state.

Expo troubleshooting

npx expo-doctor

Diagnoses version mismatches and native module issues.

Typecheck

Always run typecheck after changes:

npm run typecheck
