Conciseness

The body is dense and padding-free — hard rules, a decision table, and terse numbered steps with no explanation of concepts Claude already knows, close to the 'lean and efficient' anchor. Not 5, because the telegraphic compression ('A writer reason: 2+ independent units of behavior... each several minutes of work') occasionally sacrifices clarity for brevity and forces rereading.

Actionability

The core workflow is concrete (draft a self-contained mission with goal/paths/constraints/evidence, call delegate_task, 'Verify the claimed output (check file existence, test result, side effect)'), but step 2 points to a '## Implementation Routing' section and the 'Delegated Verification Gate' (with 'the baseline commit', 'the probe command forms') — neither exists in this SKILL.md or anywhere in the bundle — so key executable details are missing. This matches 'some concrete guidance but incomplete; missing key details', not 4, because dangling references exceed 'minor gaps'.

Workflow Clarity

Execution Steps give a clear 6-step sequence with an explicit validation checkpoint (step 5: verify the claimed output before synthesizing) and the Output Contract requires reporting 'Any discrepancy between worker self-report and verified evidence', matching 'clear sequence with most checkpoints present'. Not 5, because there is no explicit recovery path when verification fails (e.g., re-delegate, escalate, or fix inline) beyond reporting the discrepancy.

Progressive Disclosure

The SKILL.md is a well-sectioned overview (Activation Contract, Hard Rules, Decision Gates, Execution Steps, Output Contract) with exactly one clearly signaled, one-level-deep reference — references/tuning-knobs.md, which exists in the bundle and appropriately holds the delegate_task config table and mission checklist. Not 5, because the body points readers to nonexistent sections ('## Implementation Routing', the Delegated Verification Gate feature document), which breaks navigation in those spots.

Specificity

The description names the delegation domain and one concrete action ("Delegate via delegate_task"), but the trigger list ("parallel units, context backstop, high-risk verify") is compressed shorthand rather than several specific concrete actions, matching the 'names domain and 1-2 concrete actions, but not comprehensive' anchor.

Completeness

Both parts are present: what ("Delegate via delegate_task for a named reason") and explicit trigger guidance ("Trigger: a mapping need, parallel units, ..."), which counts as an equivalent of a 'Use when...' clause so the cap of 3 does not apply. Not 5, because the 'when' phrases are cryptic noun phrases rather than concrete, user-recognizable trigger phrases.

Trigger Term Quality

Relevant keywords like "delegate", "parallel", "review", and "multi-step debug" are present, but phrases such as "context backstop" and "high-risk verify" are orchestrator jargon rather than natural user phrasing, and no synonyms or variations are covered — the 'some relevant keywords but missing common variations' anchor. Not 2, because genuinely natural keywords do appear rather than only generic language.

Distinctiveness Conflict Risk

The delegate_task/ephemeral-worker orchestration niche is mostly distinct with the specific tool name anchoring it, but trigger terms like "fresh review" and "a mapping need" could overlap with skills that directly perform reviews or exploration — minor overlap risk with closely related skills rather than minimal conflict.
