Conciseness

The body is dense and purposeful, assuming Claude's competence without explaining basic concepts, but the raw-values-out-of-logs guardrail is restated across several sections (e.g., lines 31-32, 103, 137-138) and could be trimmed; efficient with minor removable repetition rather than fully lean.

Actionability

For an instruction-only skill the guidance is maximally concrete: a bounded canonical-value table, exact normalization rules (trim, fold case, spaces/underscores→hyphens), the five exact placeholders, the precise template contract (Template version: 1.0, Policy schema: 1), and exact file-handling steps (temp file, flush+sync, recheck, atomic replace, cleanup on failure).

Workflow Clarity

The six-step workflow is strictly ordered with explicit validation checkpoints — stop on invalid answer (step 3), validate template contract and stop if it differs (step 4), symlink/existence checks with recheck-before-replace and temp-file cleanup (step 5) — plus a determinism (byte-for-byte identical output) requirement, satisfying the top anchor for a destructive/file-writing operation.

Progressive Disclosure

The body is a well-sectioned overview that points one level deep to the real bundle asset [DEID-POLICY.template.md](assets/DEID-POLICY.template.md); the template content is appropriately externalized and the reference is clearly signaled, with no nested/multi-level reference chains.

Specificity

Names two concrete actions — 'Collect a bounded set of de-identification policy decisions' and 'write a deterministic, reviewable DEID-POLICY.md from the versioned local template' — described with precise modifiers; above the 1-2-action anchor (3) but short of the multi-action comprehensiveness of a 5.

Completeness

Explicitly answers both 'what' (collect decisions and write DEID-POLICY.md) and 'when' ('Use when a project needs explicit jurisdiction, recall floor, ... before privacy work begins') with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

The 'Use when' clause surfaces many natural domain terms — jurisdiction, recall floor, surrogate strategy, model policy, audit location, human approval, privacy work — plus the DEID-POLICY.md artifact name; good coverage, though it lacks synonym/file-extension breadth for a 5.

Distinctiveness Conflict Risk

Occupies a clear niche — setting up the de-identification policy document from a versioned local template — with highly specific triggers (recall floor, surrogate strategy, model policy) that distinguish it from sibling apply/audit skills; minimal conflict risk.
