focused-change SKILL.md skillA
focused-change from ymm-oss/fsl is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ymm-oss/fsl/focused-change@git:20260917.509bb63Pins git:20260917.509bb63 in mdr.lock. Pin the fingerprint instead.

Make a bounded repository change with narrow discovery, minimal diffs, staged validation, concise evidence, and controlled command output. Use for ordinary feature work, bug fixes, test additions, and small refactors with clear acceptance conditions.
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
# Focused change workflow ## Input contract Extract and keep visible only: 1. Goal 2. Target paths or symbols 3. Constraints and non-goals 4. Observable acceptance conditions 5. Required checks When one of these is missing, infer at most three low-risk assumptions from repository evidence. Do not expand the task to “improve the surrounding code.” ## FSL repository routing In the FSL repository, read [`references/fsl-repository-contract.md`](references/fsl-repository-contract.md) completely before changing implementation, tests, verification, language semantics, conformance, CLI/Worker/Kernel contracts, generated snapshots, soundness evidence, CI/product gates, or release surfaces. The reference preserves detailed repository obligations that are intentionally omitted from the short root `AGENTS.md`. For a small prose-only correction that cannot affect a contract or executable surface, the root `AGENTS.md` is sufficient. ## Discovery funnel 1. Run `git status --short`. 2. Search named symbols, error strings, tests, or routes with `rg -n`. 3. Read only the relevant ranges and immediately adjacent contracts. 4. Identify the shortest test or reproducer before changing code. …

How to install
mdr add ymm-oss/fsl/focused-change@sha256:7b58ed8c67612ff4The line at the top of this page pins the label git:20260917.509bb63, 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.
