Conciseness

Every line is a directive or concrete enumeration — "Only scan merges from the last 7 days", "Large refactors → ticket, not auto-fix", "Medium+ risk paths → escalate-human" — with no explanation of concepts Claude already knows; the untrusted-input block states loop-specific behavioral rules rather than generic prompt-injection theory.

Actionability

Concrete, actionable guidance throughout: a copy-paste output template ("### PR #N — title (merged DATE)" with risk/effort/action enums) and explicit triage rules; the gap is that no example command shows how to retrieve recent merges (e.g., `git log --merges --since=7.days` or `gh pr list --merged`), leaving a minor execution gap.

Workflow Clarity

The sequence (retrieve merges → scan each → triage → report) is implicit in the section layout but never explicitly ordered, and this batch operation over multiple merges lacks an explicit validation checkpoint (e.g., confirming a TODO is newly introduced rather than pre-existing, or that a flagged link is actually broken); the batch-operation cap at 3 applies.

Progressive Disclosure

The body is under 50 lines with no bundle files and no content that belongs in separate references; sections ("Output per merge", "What to look for", "Rules", "Untrusted input") are well-organized, and the single background link is clearly signaled and one level deep, satisfying the simple-skill exception for a top score.

Specificity

Names the domain and four concrete scan targets — "TODOs, deprecations, broken doc links, stale flags" — but the body adds "Unused imports or dead code clusters" as a category the description omits, leaving a minor coverage gap that keeps it below the comprehensive anchor 5.

Completeness

Both parts are present: a clear what ("Scan recent merges to main for follow-up cleanup: TODOs, deprecations, broken doc links, stale flags") and an explicit when ("Use in post-merge cleanup loops"), so it is not capped at 3; the when-clause is narrow and could name more concrete trigger situations, which is exactly the anchor 4 example pattern.

Trigger Term Quality

Good natural keywords users would say ("merges", "TODOs", "stale flags", "broken doc links", "post-merge cleanup"), but common variations like "follow-up work", "tech debt", or "post-merge review" are missing, matching anchor 4 rather than the synonym-complete anchor 5.

Distinctiveness Conflict Risk

"Scan recent merges to main" carves out a distinct post-merge triage niche with specific triggers, but it could still overlap with general code-review or cleanup skills in a shared library, fitting "mostly distinct; minor overlap risk".
