Notes for anyone writing or editing a plugin in this repo. Keep this short — the design principles that matter most for the quality of the output, not a style guide.

Design principle: SKILL.md encodes the right behavior; CLAUDE.md guardrails

are the net

Every plugin in this repo ships with two layers of instruction:

<plugin>/skills/<skill>/SKILL.md — what this specific skill does, step by step. The narrow, task-specific scaffold.
<plugin>/CLAUDE.md — the shared guardrails and the practice profile. "Scaffolding, not blinders," source-tag discipline, "verify user-stated legal facts," premise verification, destination check, cross-skill severity floor, pre-flight citation banner. The wide, plugin-level safety net.

If a skill's correct output depends on a CLAUDE.md guardrail catching a mistake the SKILL.md would have made, that's a design smell. The SKILL.md should tell the model what to do directly; the guardrails should catch what the SKILL.md missed. Every time a guardrail has to rescue a skill, we're relying on the guardrail firing consistently — and on a bad run, a weaker model, a terser prompt, or a future editor who reads only the skill text, the rescue doesn't happen.

Rule of thumb: if a QA test passes only because a guardrail fired, add the behavior to the SKILL.md directly. The guardrail stays (belt and suspenders), but the skill now carries the knowledge it needs on its own.

Examples of this rule in practice:

A design patent question should not pass an infringement triage only because "Scaffolding, not blinders" lets the model override the utility-patent workflow. The skill should branch on the D-prefix itself and route to the ordinary-observer test.
A renewal cancel-by date that falls on a Sunday should not land on the user's calendar correctly only because the user thought to ask about weekdays. The register schema and the Mode 2 output should carry the business-day roll-back themselves.
An FLSA back-pay computation should not get the regular-rate formula right only because the model happens to remember §207(e). The skill should have a §207(e) checklist that forces the inclusions, the 0.5× vs. 1.5× posture, the liquidated-damages doubling, and the SOL lookback into every answer.

A few concrete things that follow

Put the doctrine in the skill. If a skill's mode covers patents, cover design patents. If it covers overtime, cover the regular-rate formula. Not a pointer to "and also think about" — the actual checklist.
Attach provenance tags to numbers, not to paragraphs. [model calculation — verify against the notice clause] next to the date; [verify — consult wage-and-hour counsel before asserting or paying] on the line the back-pay number appears. Tags on surrounding prose get lost; tags on the load-bearing digit do not.
Make the decline pathway a scaffold, not an escape hatch. If the right answer to some category of question is "I decline to compute," bake that into the skill as a hard gate. legal-clinic's /deadlines do-not-compute rule is the pattern: stated plainly, non-overridable, owned by the skill.
Write the gate header so the gate is default-on. If there is an exemption, phrase the heading as the gate and narrow the exemption in a sub-bullet, not the other way around. A load-bearing parenthetical is a bug waiting to be reintroduced by the next edit.

Workflow notes

Read the plugin's CLAUDE.md before editing any skill in that plugin. The practice profile, the integrations table, the shared guardrails, and the decision-posture statement all shape what the skill should say and omit.
Bump the plugin version on a material change. Patch bumps for behavior additions; minor bumps for new skills or new required inputs.
Run the validators. scripts/validate.py and scripts/lint-tool-scope.py check the structural invariants the plugin loader depends on.
Do not remove the shared guardrails from CLAUDE.md. The net stays. The goal is a skill that doesn't need the net, not a plugin without one.
