Conciseness

Every line is operational: exact gh commands with field lists ("gh pr view <n> --json number,state,headRefName..."), exit-code semantics ("exits with 1 when a check failed and 8 when checks are pending; those are results, not failed reads"), and terse rules with no concept explanations or padding. It fully assumes Claude's competence, matching the lean every-token-earns-its-place anchor.

Actionability

Guidance is copy-paste ready: concrete gh CLI commands, a literal GraphQL query for review threads with paging, exact reply mutations ("addPullRequestReviewThreadReply(input: {pullRequestReviewThreadId, body})"), log-fetch endpoints, and concrete decision rules for each failure mode. Nothing is pseudocode or abstract, matching the fully-executable anchor.

Workflow Clarity

The "Situations" section gives an ordered dispatch list ("Take the first that applies"), with explicit validation checkpoints ("Read both again before every write", "confirm HEAD is the head you read", "reproduce it before you dispose of it") and error-recovery loops (non-convergence escalation, rerun-once with a posted run id). The numbered invariants act as a checklist for a risky batch operation (pushes and comments), matching the clear-sequence-with-explicit-validation anchor.

Progressive Disclosure

Sections are clear and well-ordered (inputs, reading, done, situations, invariants, doing the work, judgment) and the whole skill is appropriately self-contained with no buried references. It falls short of the 5 anchor because there is no reference structure at all — the multi-line inline GraphQL query and review-thread paging detail would sit equally well in a one-level-deep reference file, a minor organization gap.

Specificity

The description lists multiple concrete, comprehensive actions: "answer review feedback, fix failing checks and conflicts on the existing branch, and tell the owner when it is ready", plus the boundary "Opens no new pull request". It covers the full shepherding loop (respond, fix, notify) with no vague filler, matching the comprehensive-coverage anchor rather than the several-actions-with-gaps anchor below it.

Completeness

The "what" is clear and concrete, but there is no "Use when..." clause or equivalent explicit trigger guidance — when to invoke the skill is only weakly implied by "that Tessl opened". Per the rubric guideline, a missing explicit 'when' caps completeness at 3; it is not a 4 because the when cannot be called explicit at all.

Trigger Term Quality

Natural keywords are present: "pull request", "review feedback", "failing checks", "conflicts", "Linear or GitHub issue" — phrases a user would plausibly say. It stops short of the 5 anchor because common synonyms and variations are missing ("PR", "CI", "merge conflicts" spelled out).

Distinctiveness Conflict Risk

The niche is unmistakable: PRs opened by "Tessl" for a "Linear or GitHub issue", with an explicit scope boundary ("Opens no new pull request"). These triggers are unique to this skill and would not fire for generic PR-review or issue-management skills, matching the clear-niche anchor.
