Conciseness

The body is dense, operative prose with no re-teaching of concepts Claude already knows, and detail is delegated to references rather than inlined. It falls at the 4 anchor only because of minor repetition across sections 3-5 (preserve-recovery and 'do not claim completion' phrasing recurs) that could be tightened.

Actionability

Concrete decision rules are given ('A copy or import retains its source', 'do not edit the source to make the copy work', 'Before removing a remaining working source... verify the destination and affected references') with conditional pointers to the exact reference sections for specifics. It is not a 5 because some directives remain policy-level (e.g., 'Keep recoverable history for substantive revisions') without specifying what form that history takes.

Workflow Clarity

Five clearly sequenced stages (establish, inspect, perform, verify, report) with a dedicated verification section, an explicit error-recovery loop ('If content diverges or verification fails, preserve recoverable copies and report the unresolved difference'), and a closing checklist. This satisfies the destructive/batch validation requirement and matches the 5 anchor's checklists and feedback loops.

Progressive Disclosure

The body is a lean overview with well-signaled, conditional one-level-deep references ('For an import, copy, occupied destination, or uncertain identity, read identity and collisions'), and referenced files with valid heading anchors exist. It misses the 5 anchor because the linked 'file-management foundation' (core.md) is missing from the bundle and two existing reference files (document-maturity.md, intermediate-work.md) are never referenced from the body.

Specificity

The description lists six concrete operations ("safely move files", "rename folder", "copy directory", "archive files", "resolve destination collision", "resume interrupted file operation") plus reference repair and non-destructive moves, matching the 5 anchor's comprehensive concrete-action coverage rather than the 4 anchor's 'minor gaps'.

Completeness

It explicitly answers 'what' ("Covers safe filesystem operations, reference repair, and non-destructive moves") and 'when' ("Use this skill when the user asks to..." with six concrete trigger phrases), which matches the 5 anchor rather than the 4 anchor where the 'when' could be more explicit.

Trigger Term Quality

Trigger phrases are natural user phrasings covering each operation type, fitting the 4 anchor's 'good keyword coverage; a few natural terms missing'. It is not 5 because it gives one term per operation and omits common synonyms and variations like 'back up', 'transfer', 'import', or 'restore'.

Distinctiveness Conflict Risk

A clear niche (collision- and recovery-aware filesystem operations) with distinct triggers, reinforced by an explicit negative boundary ("Do NOT use this skill for PARA vault classification (use `para-vault`) or drafting text (use `write-like-me`)") that actively disambiguates sibling skills — minimal conflict risk.
