skill-designer SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
skill-designer from p2p2sp/viber is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add p2p2sp/viber/skill-designer@git:20261015.c0d35bfPins git:20261015.c0d35bf in mdr.lock. Pin the fingerprint instead.

Authoring doctrine for Claude Code skills and agents: one responsibility per skill, triggering description, imperative body, progressive disclosure, fork placement, lint, and per-model prompting profiles for Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5. Also for auditing or shrinking an existing SKILL.md or agent file, choosing `model:` or `effort:` for one, porting it to another model, or when an agent misbehaves on one model only (stops early, overreaches its scope, under-reports findings…
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
# skill-designer
## Input
- A request naming the skill or agent to create or change, plus any existing files.
- Optional: target directory, constraints, example inputs and outputs.
## Workflow
1. Classify the request: new, refactor, split, audit, or tune (model, effort or per-model wording only, which skips steps 2, 3, 5, 6 and 7, writes no file and ends after step 4 on the model and effort recommendation). For an existing file read it whole before touching it.
2. Run the responsibility check. If it fails or the request is a split, read `${CLAUDE_SKILL_DIR}/references/split-patterns.md` and build the split, not a bigger monolith.
3. Decide where the work runs before writing it: read `${CLAUDE_SKILL_DIR}/references/architecture.md` when the skill drives noisy tool calls, chains stages, or repeats a behaviour other skills already carry.
4. Tune for the model when the request is tune, the target is an agent or a forked skill, pins `model:`, or misbehaves on one model only. Model knowledge is as of 2026-10-07: a model with no profile below is not covered, say so and never extrapolate from a neighbour.

How to install
mdr add p2p2sp/viber/skill-designer@sha256:955838f43afddfcbThe line at the top of this page pins the label git:20261015.c0d35bf, 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.
