Conciseness

The body is lean and command-driven with no padding explaining concepts Claude already knows, but the "Common Mistakes" and "Red Flags" sections substantially duplicate each other (worktree-removal-from-inside, provenance rules, and cleanup options appear in both), which could be trimmed. It is above the 3 anchor because the excess is redundancy rather than unnecessary explanation.

Actionability

Concrete, mostly copy-paste-ready bash is given throughout (git rev-parse environment detection, git worktree remove, a complete gh pr create heredoc). Minor gaps remain: "npm test / cargo test / pytest / go test ./..." and "<test command>" are placeholders rather than executable commands, keeping it below the fully-executable 5 anchor.

Workflow Clarity

A six-step sequence with explicit validation checkpoints ("Stop. Don't proceed to Step 2", "Verify tests on merged result", "Only after merge succeeds"), a feedback loop for failing tests, typed "discard" confirmation for the destructive option, and Always/Never checklists. Destructive operations are well validated, so the cap does not apply, and the explicit gates match the 5 anchor rather than the 4 anchor's 'minor validation gaps'.

Progressive Disclosure

Well-organized single-file structure (Overview, numbered Process, Quick Reference table, Common Mistakes, Red Flags) with no nested or buried references, and the skill has no bundle files. It does not reach 5 because at ~250 lines the overlapping mistakes/red-flags material could be consolidated or split into a reference file, leaving minor organization gaps.

Specificity

"Presenting structured options for merge, PR, or cleanup" lists several concrete actions, matching the anchor for several specific actions with minor gaps; it falls short of the 5 anchor's comprehensive multi-action coverage (e.g., no mention of branch deletion or worktree cleanup as actions).

Completeness

It explicitly answers both questions: "Use when implementation is complete, all tests pass, and you need to decide how to integrate the work" gives concrete trigger conditions, and "guides completion of development work by presenting structured options for merge, PR, or cleanup" states the what. It is written in third person and clearly matches the 5 anchor rather than the 4 anchor, whose 'when' is less specific.

Trigger Term Quality

Natural phrases like "implementation is complete", "all tests pass", "integrate the work", "merge", and "PR" give good keyword coverage, but common user phrasings such as "branch", "pull request", or "finish the branch" are missing, keeping it below the comprehensive 5 anchor.

Distinctiveness Conflict Risk

The situational trigger (work complete, tests passing, deciding how to integrate) carves out a distinct niche with minimal conflict risk against general git or commit-message skills; it is more sharply scoped than the 4 anchor's 'minor overlap risk with closely related skills'.
