implement SKILL.md skillA
implement from ericrisco/rsc-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ericrisco/rsc-harness/implement@git:20261006.32bae1ePins git:20261006.32bae1e in mdr.lock. Pin the fingerprint instead.

Use when an approved plan and task list exist and it is time to turn them into working, tested code — the SDD phase after `analyze` and before `verify`. Enforces TDD: a failing test comes before the code that makes it pass, one task at a time, appended to a progress ledger that survives compaction. Delegates test tooling to the stack skill and fans disjoint tasks out via `parallel`. NOT spec writing (that is `specify`), NOT planning (that is `plan`), NOT the final lint/test/audit gate…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 does the building: it walks the tasks in order, writes each one **test-first**, stops to show its work after every task, and records the decisions it makes along the way. It is the *intent → shipped code* engine's hands — `verify` is the gate that comes after, not part of this skill. 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. ## Before you write a line of code Run this short gate. Skipping it is the most common way an implement session goes sideways. **This gate is a hard refuse, not a checklist to feel good about:** if it fails you stop and route back — you do not write feature code anyway. 1. **The spec + plan must exist AND be approved.** Open the spec (`02-DOCS/wiki/sdd/specs/<slug>.md`), …

How to install
mdr add ericrisco/rsc-harness/implement@sha256:538caf3ac84c976bThe line at the top of this page pins the label git:20261006.32bae1e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
