Write, revise or review an agent skill (SKILL.md package).
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
# Writing Great Skills - Scope = user request + settled constraints + existing authorization; skill adds no authority. - Agent prose = minimum tokens + unambiguous meaning. Use `=`, `→`, `+`, terse bullets/tables where clear; delete filler + repetition. Preserve conditions, actions, exceptions and proof; cryptic abbreviations ≠ useful compression. ## Routes Load matching routes only; Core always applies. ```mermaid flowchart LR C[Core] -->|Package / metadata / invocation| P[references/package.md] C -->|Observed skill failure| R[references/repair.md] click P "references/package.md" click R "references/repair.md" ``` ## Core | Check | Required outcome | | --- | --- | | Need | Removal loses reusable, non-default behavior; omit generic agent advice. | | Trigger | Purpose + distinct use; relevant prompts match, unrelated prompts do not. Preserve implicit selection unless user requests explicit-only. | | Disclosure | `SKILL.md` = routes + essential shared rules. Conditional workflows/examples/detail → references. Each route = load condition + direct link; load only applicable routes. Keep short universal rules inline. | …

How to install
mdr add sgaabdu4/building-flutter-apps/writing-great-skills@sha256:201b28858240ebfaThe line at the top of this page pins the label git:20260928.259bd6c, 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.
