Conciseness

Lean and operational throughout: it assumes Claude's competence, gives commands without explaining git/GitHub basics, and almost every line is a rule or an exact command. A few dense passages could still be tightened, e.g. the ready-note rules in situation 4 ("then one line for each check that does not hold on the current head: it failed outside this PR's diff, it was not run, or it ran on a narrower command..."), which keeps it just below the every-token-earns-its-place anchor.

Actionability

Fully executable guidance: exact invocations like `gh pr view <n> --json number,state,headRefName,headRefOid,baseRefName,mergeable,labels,body,comments,reviews`, the complete reviewThreads GraphQL query, `gh pr checks <n> --json name,bucket,link`, `addPullRequestReviewThreadReply(input: {pullRequestReviewThreadId, body})`, and `gh api repos/<owner>/<repo>/actions/jobs/<job id>/logs`, with exact input file paths, env vars, and marker strings. The common cases are covered copy-paste ready.

Workflow Clarity

The round is sequenced deterministically (inputs, reading the record, "Take the first that applies" situation ordering, invariants, doing the work) with explicit validation and feedback loops: "Reproduce the finding or the failure as a failing test, see it fail, fix it, and run the tests again", "Read both again before every write", "confirm HEAD is the head you read", and exit-code handling ("exits with 1 when a check failed and 8 when checks are pending; those are results, not failed reads"). The 14-item invariants list acts as a checklist, matching the top anchor.

Progressive Disclosure

A single-file skill with clean section structure (inputs, reading the record, situations, invariants, doing the work, judgment); no bundle files exist and the body references none, so all content sits one level deep. It is not a 5: at roughly 170 lines it exceeds the well-organized-single-file size, and dense operational rules (e.g. the ready-note spec) are buried inside situation 4 rather than split out, which is a minor organization gap.

Specificity

Lists multiple concrete actions covering the whole job: "answer review feedback", "fix failing checks and conflicts test-first with the build skill on the existing branch", and "tell the owner when it is ready", plus the boundary "Opens no new pull request". Coverage is comprehensive rather than leaving minor gaps, so it matches the top anchor rather than 4.

Completeness

The "what" is explicit and concrete (answer feedback, fix checks and conflicts test-first, notify the owner), but there is no "Use when..." clause or equivalent explicit trigger guidance; the "when" is only weakly implied by "a pull request that Tessl opened". Per the judging guidelines, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Good natural keyword coverage: "pull request", "review feedback", "failing checks", "Linear", "GitHub issue". A few natural terms users would say are missing ("PR", "merge conflict", "CI"), which fits the 'good coverage, a few natural terms missing' anchor rather than the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

Highly distinctive niche: "a pull request that Tessl opened for a Linear or GitHub issue", "the Perihelion way", "the build skill", and the explicit boundary "Opens no new pull request" make it unlikely to trigger for the wrong skill.
