Conciseness

The ~30-line body is lean and assumes Claude's competence: no explanation of what CQRS is, no library comparisons, no padding. The one-line intro ("Comprehensive guide to implementing..."), the only near-redundant token, mirrors the good examples' economy and keeps it at anchor 5 ('every token earns its place').

Actionability

The Instructions are high-level hints with no specific executable guidance: "Define command and query models with clear boundaries", "Implement read model projections and synchronization", "Validate performance, recovery, and failure modes" name activities but give no concrete method, commands, examples, or decision criteria. This matches anchor 2 ('high-level hints but missing the specific steps to execute') — it never reaches anchor 3's 'some concrete guidance', and the deferred detail file does not exist to rescue it.

Workflow Clarity

The four Instructions form a coherent sequence (identify → define → implement → validate), but the validation step ("Validate performance, recovery, and failure modes") has no checkpoint, method, or failure-recovery loop. This is anchor 3: 'sequence present but checkpoints missing or implicit'.

Progressive Disclosure

The structure is good on paper — clear 'Use/Do not use' sections and a single one-level-deep reference clearly signaled in a Resources section — but the referenced path `resources/implementation-playbook.md` does not exist in the bundle (no references/, resources/, scripts/, or assets/ directories are present). Scored against the actual bundle structure, the sole detail layer is a dangling pointer, so navigation fails despite the clean shape; this sits between anchor 4's 'references mostly clear' and anchor 2's structural failures.

Specificity

The description names the domain ("Command Query Responsibility Segregation", "read and write models", "event-sourced systems") and one concrete action ("Implement"), but stops there — it never mentions the actual sub-tasks involved (defining commands/queries, building projections, synchronizing read models). This matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) better than anchor 4's 'several specific actions', and is above anchor 2's minimal/generic action.

Completeness

It explicitly answers 'what' ("Implement Command Query Responsibility Segregation for scalable architectures") and 'when' with three concrete trigger phrases in a proper 'Use when...' clause, mirroring the anchor-5 example structure. It clearly exceeds anchor 4, whose 'when' is present but less specific.

Trigger Term Quality

"Use when separating read and write models, optimizing query performance, or building event-sourced systems" covers natural phrases users would say, but misses common variations — 'CQRS' itself, 'event sourcing', 'read model'/'write model' as standalone terms, or 'query-side/write-side'. Good coverage with a few natural terms missing fits anchor 4, not the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

CQRS is a fairly clear niche and triggers like "separating read and write models" are distinct, but "optimizing query performance" could overlap with general database-optimization skills and "building event-sourced systems" with a dedicated event-sourcing skill. Minor overlap risk with closely related skills fits anchor 4 rather than anchor 5's minimal conflict risk.
