phase-implement SKILL.md skillA
phase-implement from yarlson/yarstack is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add yarlson/yarstack/phase-implement@git:20261017.2f2e03bPins git:20261017.2f2e03b in mdr.lock. Pin the fingerprint instead.

Implement exactly one selected phase from an authoritative repository plan. Use when a named phase or equivalent scoped implementation unit must be completed without later-phase work.
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
# Phase Implementation Own phase scope and orchestrate only the work required to implement it. Before writing, stop at the first option that holds: the behavior is not needed, the codebase already has it, the standard library or platform does it, an installed dependency does it, or it fits in one clear line. Otherwise write the minimum that works in the fewest files, deleting before adding. Never cut trust-boundary validation, data-loss handling, security, accessibility, or anything explicitly requested. ## Workflow 1. Read the selected phase, applicable repository instructions, and the minimum local evidence needed to identify files, patterns, and required checks. 2. Confirm phase boundaries, prerequisites, acceptance criteria, and unchanged behavior. 3. Use `plan-update` for proven plan-mechanics defects and `spec-update` for non-plan semantic contract defects. 4. Use `behavior-implement` for product behavior. For tooling or infrastructure, implement directly and prove the change with the native checks, such as linters, validators, dry runs, or plans; use `behavior-implement` only when those checks cannot show behavior that matters. …

How to install
mdr add yarlson/yarstack/phase-implement@sha256:dcdc26590c0a8c36The line at the top of this page pins the label git:20261017.2f2e03b, 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.
