Conciseness

The body is dense and operational, assuming Claude knows git (no concept tutorials), but the safety line '本步骤不删除远程分支；不执行 git push --delete' is repeated three times across Steps 2, 3, and 5, and some rationale prose could be trimmed. Efficient with minor over-explanation, so 4 rather than 5.

Actionability

Guidance is fully executable throughout: concrete commands ('git worktree remove [--force] "<TARGET_ROOT>"', 'git branch -d', 'git -C "<TARGET_ROOT>" status --porcelain', 'git branch --merged master'), complete MCP call blocks with owner/repo/issue_number arguments, and platform-specific script invocations. Copy-paste ready with the common cases covered.

Workflow Clarity

Steps 0–5 are clearly sequenced with an explicit ordering rationale ('须先确认本地存在可移除的 worktree…再操作 GitHub Issue'), and the destructive operations are surrounded by validation checkpoints: master-branch check, TARGET_ROOT≠MAIN_ROOT guard, dirty-worktree consent, fetch/merge sync plus 'git branch --merged' confirmation via AskQuestion, issue-state read before closing, and '-d' refusal handling. Because validation and feedback loops (abort on fetch failure, user decides on MCP failure) are explicit, the destructive-operation cap at 3 does not apply.

Progressive Disclosure

A single well-organized file with clear sections and no nested references, appropriate for a ~150-line workflow. It falls short of 5 because 方式 B in Step 4 references scripts under '.cursor/skills/github-worktree/scripts/' that are not part of this bundle (no references/, scripts/, or assets/ directories exist), an external dependency that is neither bundled nor clearly signaled as belonging to another skill.

Specificity

The description lists multiple concrete actions — '将指定分支关联的 GitHub Issue 关闭（可选并确认），移除本地 git worktree 目录与本地分支（不删除远程分支）' — plus explicit constraints ('必须在 master 分支上执行', branch selection fallback), giving comprehensive coverage of the skill's scope. It is not a 4 because there are no minor gaps: every capability of the workflow is named.

Completeness

Both 'what' (close the linked GitHub issue, remove the local worktree, delete the local branch) and 'when' are answered explicitly with concrete trigger phrasing: '在用户显式 @ 本 skill 或明确下达「关闭 worktree 并完成需求」类指令时…须以用户主动调用本工作流为准'. Not a 4, because the 'when' clause is explicit and specific rather than merely present.

Trigger Term Quality

Natural trigger phrasing is present ('关闭 worktree 并完成需求', GitHub, issue, worktree, git, 分支), matching how a user would invoke this. It falls short of the 5 anchor because common synonyms and variations (e.g. 清理/删除 worktree, close issue, 删除本地分支) are not covered.

Distinctiveness Conflict Risk

The description carves out a clear niche and actively guards against false triggers — '不得因仅提及 GitHub、issue、worktree、git 等词而自动套用' — so conflict with other git/GitHub skills is minimal. Not a 4, because the negative trigger guard makes overlap risk essentially explicit and controlled.
