The body is thorough and mostly domain-specific policy Claude would not know, but key rules are restated multiple times (the PR-scoped-vs-sweep distinction recurs in the procedure, Modes, Phase 0.5, Phase 2 and Phase 3; "no guessing" repeats in four places), so it could be tightened. It is not level 1 because the content is genuine project policy rather than generic concepts Claude already knows.

It provides concrete executable commands (git diff --name-only main...HEAD, merge-base then diff, docker buildx bake validate) and a real scope-pr-files.sh helper, but the core link-edit steps are described as prose ("Replace old source paths... preserve each file's link pattern") rather than given as copy-paste-ready commands. It is not level 3 because the central editing actions are not fully executable code.

The multi-step process is explicitly sequenced (Phases 0→0.5→1→2→3 plus a mandatory "Run in order" list) with a validation checkpoint (docker buildx bake validate), a re-sweep feedback loop ("re-print or re-scan for List 2 until empty or deferred"), and a Definition-of-done checklist, matching the anchor for clear sequence with explicit validation and feedback loops.

There is one real bundle file (scripts/scope-pr-files.sh) referenced correctly and a convention for an optional reference.md, with no deeply nested references; however the detailed Conventions and Phase sections remain inline in a ~370-line SKILL.md rather than being split into well-signaled one-level-deep reference files. It is not level 1 because sections are headed and organized, and not level 3 because content that could be separate is left inline.

Multiple concrete actions are named ("discover old vs new URLs", "add front matter aliases", "update in-repo links", "interactive List 2 resolution and fragment validation"), matching the anchor for listing several specific concrete actions rather than naming only a domain and some actions.

It clearly answers both what (the phase-based actions) and when (the explicit "Triggers on:" list), matching the anchor for clearly answering both what AND when with explicit triggers rather than having when only implied.

An explicit "Triggers on:" clause lists five natural phrases a user would say ("IA migration", "redirects for moved pages", "fix links after content move", "PR-scoped link/anchor pass", "aliases for old URLs"), giving good coverage rather than only some relevant keywords.

The niche is narrow and domain-specific (Hugo docs IA moves, front matter aliases, redirect/list-2/fragment handling) with distinct triggers, making it unlikely to fire for an unrelated skill; not merely somewhat specific with overlap.
