=========

Implement one slice from a spec using TDD at pre-agreed seams, review it
with slice-review, and commit — one slice at a time.

Description
-----------

The implement skill is the ship stage of the slice loop, with a
work-in-progress limit of one. It picks the first slice on the frontier
(all blockers done, status ``ready``), confirms the choice, builds it
with the ``tdd`` skill from the slice's acceptance criteria, reviews the
diff with ``slice-review``, then commits and ticks the slice off in both
the slice file and the spec's slices checklist.

It stops after one slice and reports the new frontier. When the final
slice of a spec lands, it recommends a whole-spec review with
``team-review-impl``.

Triggers
--------

.. code-block:: text

   /wf:implement
   /wf:implement resources/agent-docs/specs/001-feature/slices/02-checkout.md

Also: "implement the next slice", "work the frontier".

Workflow
--------

1. Pick (or accept) the slice; confirm with the user.
2. Read the slice, spec, glossary, and relevant ADRs.
3. TDD from the acceptance criteria at the pre-agreed seams.
4. Type checks and single test files regularly; full suite at the end.
5. ``slice-review`` against the pre-slice commit; address findings.
6. Commit, set status ``done``, tick the checklists, stop.

Output
------

One commit per slice, updated slice file and spec checklist, and a
frontier report.
