Conciseness

The body is dense operational rules with no basic-concept padding, but the core 'verify before persist' discipline is restated roughly five times (loop diagram, 'What this skill is for', verification rules, anti-patterns, best practices), and the motivational failure-modes intro plus the hedging-heavy 'When a skill contributed to the failure' section could be trimmed. This matches anchor 3 (mostly efficient but includes some unnecessary explanation or could be tightened) better than anchor 4 — the repetition goes beyond minor over-explanation.

Actionability

Provides a copy-paste-ready HEAL entry template, an exact grep command for recurrence detection, setup commands, ID format with examples, and a proof-criteria table per failure shape. Fully executable guidance covering the common cases, matching anchor 5; there are no execution gaps in the core workflow.

Workflow Clarity

The Heal Loop diagram sequences DIAGNOSE→PATCH→VERIFY→FILE with a 3-attempt retry cap, an explicit escalation ladder on verification failure (once/twice/three times), an abandonment path, and failure classification (deterministic/transient/shared-service) required before any retry. This is the exact validate→fix→retry feedback-loop pattern with explicit checkpoints that anchor 5 describes.

Progressive Disclosure

All four references (examples.md, hooks.md, interop-with-self-improvement.md, pipeline-integration.md) exist, are clearly signaled with one-line purpose annotations, and are one level deep. However, the three bundled scripts (new-heal.sh, find-similar-heals.sh, detect-failure.sh) are never mentioned in the body — it teaches manual grep and manual entry writing while executable helpers sit undocumented. Good structure with a real but contained organization gap, matching anchor 4 rather than the fully-split anchor 5.

Specificity

Lists multiple concrete actions covering the entire loop — 'diagnose the root cause, write a fix, VERIFY by re-running the broken thing, then file a HEAL- entry to .learnings/HEALS.md with proof' — plus recurrence handling ('increment Recurrence-Count instead of duplicating') and honest status marking ('pending-verify', 'abandoned'). Comprehensive coverage with no gaps, matching anchor 5 rather than anchor 4.

Completeness

Explicitly answers both questions: the what ('Active runtime recovery... diagnose, write a fix, VERIFY by re-running the broken thing, then file a HEAL- entry with proof') and the when ('Use whenever a command, test, build, or lint fails or exits non-zero; on missing tooling...'). Both are concrete and fully explicit, matching anchor 5 rather than anchor 4's 'when could be more specific'.

Trigger Term Quality

Covers the natural trigger phrases an agent or user would actually encounter: 'command, test, build, or lint fails or exits non-zero', 'dependency/lockfile mismatch', 'venv or permission errors', 'port conflicts', 'dirty git state', 'missing .env', 'errors or rate-limits', 'test flakes', plus the helper-gap case. Includes synonyms and concrete file names, matching anchor 5's comprehensive coverage rather than anchor 4's 'a few natural terms missing'.

Distinctiveness Conflict Risk

The description explicitly draws the boundary with its closest sibling — 'Pairs with self-improvement... but owns the verify-before-persist discipline self-improvement doesn't' — and its failure-shaped triggers (non-zero exits, missing .env, port conflicts) are distinct from self-improvement's reflective triggers. Still, 'when a test flakes' and recurrence handling sit near self-improvement's territory, leaving minor overlap risk with a closely related skill, which is exactly anchor 4 rather than anchor 5's minimal-conflict niche.
