Conciseness

Every section carries only operational facts (phase mask, size floor, first move, gates, security-reviewer condition) with zero known-concept explanation or padding; even the 'Related:' blockquote earns its place as skill disambiguation. Matches the lean-and-efficient anchor exactly.

Actionability

Concrete, executable settings ('Phase mask: 0 → 1 → 2 → 4 → 5 → 6', 'write *new* failing tests for the new behavior, then implement to green', conditional security-reviewer rule), but the executable core is fully delegated to the orch-pipeline engine, which is not part of this bundle. Mostly executable guidance with minor gaps — anchor 4, not 5.

Workflow Clarity

Clear sequence (classify size → research → plan → TDD → review → commit) with two explicit checkpoints ('Stop at **Gate 1** (plan approval) and **Gate 2** (pre-commit)'). Not anchor 5 because error-recovery feedback loops are only implied (TDD 'implement to green') rather than detailed; not destructive/batch, so the cap at 3 does not apply.

Progressive Disclosure

Under 50 lines with well-organized sections and a single clearly-signaled, one-level-deep reference to the shared engine — good structure. Falls short of anchor 5 because the referenced '../orch-pipeline/SKILL.md' does not resolve from this skill's directory, leaving the body's one detail anchor unverifiable.

Specificity

Lists the full concrete pipeline — 'research, plan, TDD implementation, review, and gated commit — by delegating each phase to the matching ECC agent' — comprehensive coverage of the capability with no gaps.

Completeness

Both what (end-to-end orchestration via delegated phases) and when (explicit 'Use when' clause) are present, matching anchor 4. Not 5 because the when-clause offers a single trigger phrase where the anchor-5 example provides multiple concrete trigger phrasings.

Trigger Term Quality

The trigger surface is only 'Use when adding a capability that does not exist yet' — the key natural term 'add' is present, but common variations users say ('build', 'implement', 'create', 'support') are absent from the description. Fits 'some relevant keywords but missing common variations or synonyms' rather than anchor 4's 'good keyword coverage'.

Distinctiveness Conflict Risk

'a capability that does not exist yet' carves a clear niche against fix/change variants, but overlap risk remains with generic feature-building skills (a standalone '/feature-dev' version exists per the body). Mostly distinct with minor overlap against closely related skills — anchor 4, not the minimal-conflict anchor 5.
