Conciseness

The body is lean, imperative, and assumes Claude's competence throughout — it never explains what a PR or git is, and every instruction adds non-obvious policy ("Never assume main", "do not rebase or force-push as part of this skill"). The only near-redundancy is the duplicated "$ARGUMENTS" note, which is trivial; this matches the 'every token earns its place' anchor.

Actionability

Guidance is highly concrete: an ordered base-resolution procedure, an exact fallback PR body template in a copy-paste markdown block, explicit flag rules ("--base <branch>", "Use --draft only when the user explicitly requests a draft"), and concrete bad/good title examples. Not a 5 because the actual `gh pr create` invocation is described but never shown as a complete command line, leaving a minor gap for the single most important execution step.

Workflow Clarity

Five clearly sequenced sections (establish target → validate work → write PR → push and create → verify and report) with explicit validation checkpoints: re-reading the merge-base diff, comparing against the requested outcome, checking for existing PRs, and verifying the created PR's number/base/head before reporting success. Stop-and-ask and stop-and-report error paths cover recovery, matching the top anchor including feedback loops.

Progressive Disclosure

This is a single-file skill with no references/, scripts/, or assets/ bundle; nothing needs to be split out, sections are well-organized with a clear hierarchy (Scope → numbered steps → Title/Description subsections), and there are no nested or dead references. Per the rubric's guidance to score against the actual bundle structure, a self-contained skill with well-organized sections warrants the top score.

Specificity

"Creates and opens GitHub pull requests" names the domain and one core action pair, but does not list the several specific capabilities the skill actually performs (title/body authoring, base resolution, validation, CI checks), matching the '1-2 concrete actions, not comprehensive' anchor. It is not a 4 because no enumeration of several specific actions appears, and not a 2 because the action named is concrete rather than generic.

Completeness

It clearly answers 'what' ("Creates and opens GitHub pull requests") and 'when' with an explicit "Always use when" clause listing four concrete trigger conditions. Not a 4 because the 'when' is fully explicit with multiple concrete trigger phrases, exactly matching the top anchor.

Trigger Term Quality

Triggers include natural phrases users would say — "creating a PR on GitHub", "create or open a PR" — plus the explicit "$prp-pr" invocation, giving good keyword coverage. Not a 5 because common synonyms like "submit a PR", "open a pull request", or "draft PR" are missing.

Distinctiveness Conflict Risk

The niche (GitHub PR creation) is clear and the triggers — including the unique "$prp-pr" invocation and the PRP-workflow step — are distinct, so conflict with other skills is minimal. Not a 4 because nothing about the description broadly overlaps neighboring skills like commit-message or PR-review skills.
