implement is agent-read markdown (skill) from firzus/agent-skills: Deliver prepared work with test-first verification, current documentation, and a verified handoff..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Implement a verified change
Deliver one coherent, reviewable outcome. Tests, context, and affected documentation
belong to the change; an implementation request does not authorize unrelated work,
external publication, merge, or deployment.
## 1. Read the work and verify readiness
1. Read the request, project instructions, current repository state, and existing
work record. For a Linear issue, include comments, linked decisions, acceptance
criteria, prerequisites, and delivery boundary.
2. Apply [intake and handoff](references/intake-and-handoff.md) to verify the work
type, ownership, prerequisites, prototype version, and context changes.
3. Trace the affected behavior through callers, contracts, configuration, and tests.
Separate unrelated local work and pre-existing failures.
4. Resolve discoverable facts locally. For consequential open choices or conflicts,
record the decision needed and propose returning to interview; pause only the
dependent work. A ready label alone is not evidence of readiness.
**Done:** scope, prerequisites, authorization, and independent acceptance evidence
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
