Individual skill

implement

Use when an approved plan and task list exist and it is time to turn them into working, reviewed code — ASDD stage 4, the per-task loop after `analyze`: TDD build and self-check, `rsc risk` on the diff, review scaled by tier (0/1/3 reviewers), mandatory controls (tests, build, security, traceability), at most 3 fix rounds, then fix-and-record or park in the decision queue. Progress ledger survives compaction; disjoint tasks fan out via `parallel`. NOT spec writing (that is `specify`), NOT planning (that is `plan`), NOT the closing whole-branch gate (stage 5: `verify` + `review`).

# implement — turn the task list into tested code

You have a spec, a plan, and an ordered task list (from `specify` → `plan` → `tasks`), and the
`analyze` gate has cleared. This skill is **ASDD stage 4**: it walks the tasks in order and runs each
one through a build → risk → review → controls → fix → decide loop before the next starts. Review
lives *inside* the task, not after the branch: tests prove the code works, not that it is what was
asked, and an unrequested feature caught at one commit is cheap — caught under thousands of green
tests at the end, it is not.

This is a **process skill**. It owns the discipline (red → green → refactor, checkpoints, decision
logging, constitution adherence). It does **not** own the test tooling — pytest fixtures, `go test`
table-drivers, Vitest/Playwright, `flutter test` — those belong to the stack skill, and you call
into them rather than reinventing them.
