Diff Skill Instructions

Goal: Detect whether an edit to a skill's markdown instructions introduced degradations or made the skill harder for an LLM to follow.

Two judgment axes:

1. Degradation (asymmetric) — load-bearing instruction dropped, constraint weakened, verification step removed, scope narrowed, required output dropped, or reference broken. Content relocated but preserved is neutral.
2. Complexity — split into regressions (introduced or worsened by the edit, affects verdict) and pre-existing advisories (exist regardless of the edit, surfaced as improvement opportunities, does NOT affect verdict).

Conventions

• Read capy knowledge base conventions at shared-capy-knowledge-protocol.md.

Required Outputs

• Report written to docs/reviews/diff-skill/<slug>-<sha-a>-<sha-b>.md
• Inline summary presented (under 10 lines: verdict, finding counts, report path)
• Capy indexed under kk:review-findings if any degradation or complexity regression findings exist (skip on clean results and pre-existing advisories)

Invocation

/kk:diff-skill <skill-name>

Convenience shortcut: resolves klaude-plugin/skills/<skill-name>/SKILL.md. If not found, asks the user for the skill directory path.

Defaults: HEAD (before) → working tree (after). User can specify different refs in the prompt.

Workflow

Mandatory order — load instructions before acting on subject matter. The phases below are strictly sequential. Do not read skill content, build file sets, or produce judgments until you have loaded and internalized the full process file. The only early contact with the target skill is its name and SKILL.md path — enough to validate, not enough to judge.

See diff-process.md for the detailed step-by-step process.
