First Objective

Start the Daemon

tack daemon --config .tack/config.yaml

The daemon runs in the foreground. Open a new terminal for CLI commands.

Submit an Objective

tack plan "Refactor the auth module to use JWT"

Tack creates an objective and spawns a planner agent. The planner explores your codebase and decomposes the objective into parallel streams with file scopes and dependencies.

Review the Plan

tack plans
tack show <plan-id>

The plan shows each stream's title, description, file scope, and dependency chain. Review it before approving.

Approve

tack approve <plan-id>

Execution begins. Tack schedules streams based on dependencies and concurrency limits.

Watch Progress

tack watch

Live stream of agent activity — tool calls, file edits, test results, and status changes.

18:16:12 [stream-1] builder: read src/schemas.ts
18:16:15 [stream-1] builder: edit src/routes/expenses.ts

18:47:35 [stream-1] merged ✓

Check Results

tack status
tack merge

When all streams complete, Tack merges everything and creates a PR.

Simple Mode

For smaller tasks that don't need decomposition:

tack plan "Fix the typo in the README" --simple

Simple mode creates a single-stream plan and auto-approves it. One agent, no planning overhead.
