Conciseness

The body is dense and lean — file-path tables, a symptom→verdict→fix-target decision table, and bare commands with no explanation of concepts Claude already knows. Not a 5 because of one clear redundancy: the "To reproduce judge graders locally" block in Rule 0 repeats the exact same vitest command already given two lines above, and "Step 0 command" in Step 4 refers to a section labeled "Rule 0" (a small naming mismatch). Not a 3: there is no unnecessary explanation or padding anywhere else.

Actionability

Fully executable guidance throughout: a copy-paste-ready re-run command (`pnpm --filter @novu/agent-evals exec vitest run --config vitest.evals.config.ts -t <scenario-id>`), exact file paths for every grader layer (`src/suites/agent-onboarding/scenarios/<id>/graders.ts`, `catalog.ts`, `src/core/graders.ts`, `src/core/judge.ts`), the concrete pass threshold (`averages ≥ 0.8 (JUDGE_THRESHOLD)`, `UNKNOWN`→`skip` scores 1), a grader-kind decision table, and a fill-in-the-blanks output template. Not a 4: there are no gaps — the common triage case is covered end-to-end.

Workflow Clarity

The sequence is explicit and gated: Rule 0 (re-run 3–5× to rule out flakiness before changing anything) → identify grader kind → read RunResult evidence → classify via top-down decision table → apply one bounded fix and verify. Validation checkpoints are explicit at every stage: "Confirm the fix holds across the 3–5 re-runs and that no other scenario regressed" and running the synthetic unit tests when a grader is edited. This matches the top anchor (feedback loops, explicit validation, ordered first-match classification).

Progressive Disclosure

The body itself is well structured with clear sections, but the single external reference is broken: "For worked triage examples ... see [reference.md](reference.md)" points to a file that does not exist in the bundle (no references/ directory), so navigation dead-ends and the promised worked examples are unavailable. Not a 4: a clearly signaled but missing reference is a real navigation defect, not a minor organization gap; not a 2: the body is appropriately sized and organized rather than a monolith that should be split.

Specificity

The description lists multiple concrete actions — "Triage failing @novu/agent-evals scenarios to decide whether a failure is real or flaky, and whether to fix the playbook/prompt or the test (grader, tape, scenario, or judge)" — with comprehensive coverage of the decision space (real vs flaky, playbook vs test, and the four test-layer targets). Not the level below (4): there are no meaningful coverage gaps; the enumerated fix targets (grader, tape, scenario, judge) make the actions fully concrete.

Completeness

Both halves are explicit: the 'what' (triage a failing scenario and classify the failure as real vs flaky, and identify the fix target) and the 'when' via a concrete "Use when..." clause with three distinct trigger conditions. This matches the top anchor exactly; the 'when' is explicit with concrete trigger phrases, not merely implied (level 4).

Trigger Term Quality

Good natural trigger phrases: "when an agent-evals scenario fails", "when the user asks why an eval is red", "when deciding whether to fix the test or the prompt" — phrasings a user would plausibly say. Not a 5: a few common synonyms are missing (e.g., "flaky test", "eval failing in CI", "failing scenario in the eval suite"). Not a 3: the coverage clearly exceeds 'some relevant keywords'.

Distinctiveness Conflict Risk

The niche is narrow and product-specific (@novu/agent-evals scenario triage with named layers like grader, tape, judge), so it is clearly distinguishable from generic testing/debugging skills and carries minimal conflict risk. Level 4 would require some overlap with closely related skills, which the strong domain binding avoids.
