Conciseness

The body is lean and efficient ('Target Patronum v2.x by default', 'Prefer concise examples with explicit imports') with zero padding and no explanation of concepts Claude already knows about Effector or Patronum. Every section — Workflow, Defaults, Guardrails, Output Template — earns its tokens, matching the anchor-5 example of assuming competence.

Actionability

Mostly concrete, directive guidance: 'Prefer `patronum/<operator-kebab-name>` imports when clarity matters', 'Do not skip edge cases for `pending`, `condition`, `interval`, `time`, and `debug`', and an explicit three-part output template. It falls short of anchor 5 because no minimal code snippet or worked micro-example appears inline, and 'Build answer contract' steps remain somewhat abstract; it is clearly above anchor 3's pseudocode/incomplete level.

Workflow Clarity

The sequence is clear — classify request into five named categories, load references progressively with conditional triggers ('Add `references/migration-notes.md` when legacy forms appear'), then build the answer — with a defined output structure. Anchor 5 is not met because there is no verification step (e.g., confirming the chosen operator exists in the matrix before recommending it), leaving checkpoints implicit; this is well above anchor 3's 'sequence present but checkpoints missing'.

Progressive Disclosure

The body is a concise overview that clearly signals one-level-deep references in an explicit load order: 'Start with `references/operator-matrix.md`', then 'Add `references/recipes.md`', '`references/pitfalls.md`', and '`references/migration-notes.md`'. All four referenced files actually exist in the bundle, paths match exactly, and content is appropriately split with easy navigation, matching the anchor-5 example.

Specificity

The description lists multiple concrete actions — 'Select and apply Patronum operators', 'composing reactive state flows', 'replacing manual sample/combine boilerplate', 'explaining operator signatures and return types', 'adapting legacy Patronum usage to modern v2 shorthand' — giving comprehensive coverage for the domain. It exceeds the anchor-4 example ('minor gaps in coverage').

Completeness

It explicitly answers both questions: what ('Select and apply Patronum operators for Effector code with minimal, practical v2.x examples') and when ('Use when tasks involve choosing between Patronum operators, composing reactive state flows, ... or adapting legacy Patronum usage'). The explicit 'Use when' clause with concrete trigger phrases matches the anchor-5 example; anchor 4's 'when could be more explicit' does not apply here.

Trigger Term Quality

Natural trigger phrases are well covered ('Patronum operators', 'Effector code', 'signatures and return types', 'import patterns', 'sample/combine boilerplate'), but a few common user asks are missing such as specific operator names like 'debug', 'pending', or 'interval' that users frequently request. Good coverage with a few natural terms missing matches anchor 4 rather than the comprehensive anchor 5.

Distinctiveness Conflict Risk

The Patronum/Effector niche is highly specific with distinct triggers ('Patronum operators', 'Effector code', 'v2 shorthand'), so it is clearly distinguishable from other skills and unlikely to trigger wrongly. Minimal conflict risk matches anchor 5.
