Conciseness

The body is dominated by team-specific conventions Claude cannot infer (naming taxonomy, lifecycle rules, checklist), but the Standard Commands section re-teaches basic git (`git checkout -b`, `git rebase`, branch deletion) and the Trigger Boundary section restates the frontmatter description. These minor instances of over-explanation fit anchor 4 rather than the fully lean anchor 5.

Actionability

Guidance is fully executable: copy-paste-ready bash for creating feature branches, hotfixes, rebasing, and post-merge deletion, plus a concrete prefix/scope/example table and ticket-key naming examples that cover the common cases. This matches the anchor-5 standard for an instruction-only skill.

Workflow Clarity

The numbered Branch Lifecycle Rules, Standard Commands, and Review Checklist together give a clear sequence with most checkpoints (fetch-before-branch, CI verification via PR, rebase-before-PR). It falls short of anchor 5 because there is no single ordered end-to-end workflow with feedback loops, and the destructive `git push origin --delete` step has no explicit pre-deletion validation; it stays above anchor 3 because the checklist supplies explicit verification steps.

Progressive Disclosure

The body is a well-organized overview (TOC, tight sections) and the deeper material — branching models, CI/CD triggers, hotfix workflows, anti-patterns — is appropriately split into a single clearly signaled, one-level-deep reference (references/branch-conventions.md) that exists and matches its advertised contents. This matches the anchor-5 structure.

Specificity

The description lists multiple concrete capabilities — "Git branch creation, naming taxonomies (feat/, fix/, refactor/, hotfix/, release/, chore/), trunk-based integration, and PR isolation lifecycles" — which comprehensively cover the branch-management domain from creation through PR integration. It exceeds anchor 4 because coverage of the skill's scope is complete rather than having minor gaps.

Completeness

It explicitly answers "what" (branch creation, naming taxonomies, trunk-based integration, PR isolation lifecycles) and "when" ("Use when creating branches, preparing pull requests, or standardizing team git workflows") with concrete trigger phrases, matching the anchor-5 example pattern.

Trigger Term Quality

Natural phrases like "creating branches", "preparing pull requests", "standardizing team git workflows", and "merge conflicts" match what users would say, plus prefix keywords (feat/, hotfix/). A few common synonyms are missing ("PR", "feature branch", "branch naming"), so it fits anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

It occupies a clear niche (git branch lifecycle management) with distinct triggers, and the explicit exclusion clause "do not use for resolving merge conflicts or low-level git plumbing" minimizes conflict with adjacent git skills. Not anchor 4 because the negative boundary removes even the minor overlap risk.
