go-code-reduce from yarlson/yarstack is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Find and, when authorized, apply maintainable Go code reductions. Use when a user asks to reduce Go lines, boilerplate, duplication, or obsolete idioms without changing behavior; not for general implementation or style review.
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
# Reduce Go Code Reduce authored maintenance burden, not raw repository lines. Prefer deleting mechanics through standard Go constructs over compressing domain logic or introducing project-specific abstractions. ## Workflow 1. Read the repository guidance, module Go version, closest source and tests, generated-file markers, and affected public consumers. Keep an assessment read-only unless edits are authorized. 2. State the behavior that must remain unchanged, including errors and wrapped identities, nil versus empty values, ordering, serialization, cancellation, cleanup, exported APIs, build variants, and relevant performance bounds. 3. Rank evidenced candidates in this order: - delete dead, obsolete, forwarding, compatibility, or unnecessarily exported code when consumers permit it; - replace hand-written mechanics with version-supported language, built-in, or standard-library operations; - shrink producer APIs and define small interfaces at actual consumers; - consolidate an algorithm only when multiple real copies differ solely by type or repeated traversal; - generate code only when repetition is mechanically derived from one authoritative source; …

How to install
mdr add yarlson/yarstack/go-code-reduce@sha256:0ba1cc0d76d87588The 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.
