Conciseness

The body is lean and imperative, assumes Claude's competence (never explains what worktrees or rate limits are), and every operational rule is project-specific knowledge Claude wouldn't have. Minor trimming opportunities remain — the 'When to use' trigger list restates the frontmatter description nearly verbatim, and a few sub-bullets in the low-token strategy could be consolidated — so it fits 'efficient; minor instances of over-explanation' rather than 'every token earns its place'.

Actionability

Concrete, executable guidance throughout: exact draft file naming ('.tmp/pr-body-issue-123-scope-summary.md', not a shared '.tmp/pr-body.md'), a specific template source ('.github/pull_request_template.md'), and quantified API budgets (~20 MCP read calls, ~5 mutations, 5 secondary-limit points per mutation). Validation steps delegate to repo-specific commands by design but remain slightly abstract ('Run targeted checks first, then required project checks'), keeping it below fully copy-paste-ready.

Workflow Clarity

A clear 10-step numbered sequence with an explicit validation checkpoint and feedback loop ('If checks fail, fix relevant issues and re-run before proceeding'), confirmation gates before every mutation ('Before any GitHub mutation... ask for explicit user confirmation'), and a checklist asset for the complex process. This matches the top anchor: explicit validation steps, error-recovery loops, and a checklist.

Progressive Disclosure

The one bundle file (assets/issue-solving-checklist.md) exists, is one level deep, and is clearly signaled from a dedicated Assets section. Structure is good, but the ~120-line body keeps substantial operational detail inline — notably the eight-bullet low-token/rate-limit strategy — that would fit a reference file, matching 'good structure; most content appropriately placed; minor organization gaps' rather than the cleanest split.

Specificity

The description names the domain ('GitHub issue resolution end-to-end') but the capability statement is a single generic action — no concrete actions such as implement, validate, or prepare PR are listed. All the concrete material consists of trigger phrases rather than capabilities, matching the anchor for 'names the domain but actions are minimal or generic'.

Completeness

Both 'what' ('Handles GitHub issue resolution end-to-end') and 'when' ('USE FOR: solve #123, continue work on issue #123...') are explicitly present, and the when-clause includes concrete trigger phrases. The 'what' is high-level rather than enumerating the work performed, placing it between the anchor requiring a fully comprehensive what-and-when pair and the anchor where only 'when' could be more explicit.

Trigger Term Quality

Comprehensive natural trigger coverage including synonyms and URL forms: 'solve #123', 'lets solve #123', 'work on #123', 'continue work on issue #123', 'work on https://github.com/owner/repo/issues/123', and pasting a direct issue URL. No common variation a user would say is missing.

Distinctiveness Conflict Risk

Clear niche (end-to-end issue implementation) with explicit negative boundaries ('DO NOT USE FOR: issue drafting only, PR review only, or non-implementation research') that sharply reduce overlap risk with adjacent authoring/review skills. Triggers are distinct and unlikely to fire the wrong skill.
