Conciseness

Mostly efficient prose without explaining concepts Claude already knows, but the ~370-line body carries clear slack: two changelog-style version-comparison tables ('What's New in v2.1', 'What's New in v2 (vs v1)'), a long ASCII architecture diagram, a design-rationale section ('Why Hooks vs Skills for Observation'), and a duplicated command listing (bash block in Quick Start plus the Commands table). Not a 4 because multiple sections could be trimmed or moved without losing operational value.

Actionability

Largely copy-paste ready: the exact settings.json hook block, mkdir commands, a config.json example with a key/default/description table, and concrete CLI invocations like 'python3 instinct-cli.py promote --dry-run'. Not a 5 because some paths are ambiguous ('instinct-cli.py' is referenced without its scripts/ location, and /commands are listed with no pointer to where they are defined).

Workflow Clarity

Quick Start gives a clear numbered sequence (enable hooks → initialize directories → use commands) with distinct install paths (plugin vs manual) and a warning about duplicated hook blocks. Validation checkpoints exist for risky operations (promote --dry-run, observer non-survival warning with ECC_OBSERVER_NOSURVIVE_WARN_AFTER). Not a 5 because import/evolve operations lack equivalent verification steps.

Progressive Disclosure

Sections are well organized, but the bundle structure undercuts navigation: the body references 'hooks/observe.sh' and 'hooks/hooks.json', which do not exist in the bundle (no hooks/ directory), and 'config.json' as an editable observer config while the heavy logic lives in scripts/ (91KB instinct-cli.py) with no pointers into it. Substantial inline material (file-structure listing, scope guide, confidence tables) is appropriate for one-level structure, but broken/missing referenced paths and the absence of any references/ files leave it between the 3 and 4 anchors.

Specificity

Lists several concrete actions — 'observes sessions via hooks', 'creates atomic instincts with confidence scoring', 'evolves them into skills/commands/agents' — with only minor gaps (export/import of instincts is not mentioned). Not a 5 because coverage is not fully comprehensive; not a 3 because it clearly goes beyond 1-2 generic actions.

Completeness

Explicitly answers both 'what' (observes sessions via hooks, creates atomic instincts with confidence scoring, evolves into skills/commands/agents) and 'when' with a concrete 'Use when...' clause listing three trigger scenarios. Matches the 5 anchor closely.

Trigger Term Quality

Good natural trigger phrases: 'capturing lessons from a session', 'managing instincts', 'promoting them into skills, commands, or agents'. A few natural terms are missing (e.g., 'learning from sessions', 'remembering preferences', 'reusing patterns'), and 'instinct' is project-specific jargon users may not say unprompted, keeping it below 5.

Distinctiveness Conflict Risk

The hook-based observation / instinct lifecycle is a fairly distinct niche with specific triggers (instincts, promotion). Minor overlap risk with generic memory or learning skills; not a 5 because 'learning system' and 'skills/commands/agents' could pull it into broader skill-selection contexts.
