The body is lean and directive — short bulleted rules with no padding and no explanation of concepts Claude already knows — fitting 'Lean and efficient; assumes Claude's competence; every token earns its place'; it is not a 2 because there is no unnecessary explanation to tighten.

A few rules give semi-concrete direction ("If a rule is organizational, enforce it on the server", "capture it as a skill or project convention"), but most are aphoristic principles ("Product coherence beats local cleverness", "Treat design, architecture, and business rules as one system"), fitting 'Some concrete guidance but incomplete... missing key details'; it is not a 1 because some directives are actionable, and not a 3 because the guidance is mostly abstract rather than copy-paste ready.

This is a non-procedural norms skill (under 50 lines) whose content is clear and well-organized into labeled sections; per the simple-skills note, workflow_clarity can score 3 when content is clear and well-organized even without an explicit multi-step workflow, and no destructive/batch operations require validation checkpoints.

No bundle files are provided and none are needed; the single self-contained file is organized into well-signaled sections (When to Use, Cultural Rules, Collaboration Rules), and per the simple-skills note a sub-50-line skill with no need for external references scores 3 with just well-organized sections.

It names a clear domain ("Cultural and collaboration norms for Engram contributors and agents") but offers no concrete actions or verbs in the 'what' clause, matching 'Names domain and some actions, but not comprehensive'; it is not a 1 because the Engram scoping lifts it above pure vagueness, and not a 3 because no distinct concrete actions are listed.

It answers both what (cultural/collaboration norms) and when, with an explicit "Trigger:" clause, matching 'Clearly answers both what AND when with explicit triggers'; it exceeds 2 because the when is explicit rather than implied, satisfying the 'Use when... or equivalent explicit trigger guidance' requirement.

The "Trigger: Starting substantial work, reviewing changes, or defining team conventions" phrases are relevant and partly natural (e.g., 'reviewing changes'), but they are abstract process terms missing common concrete variations, fitting 'Some relevant keywords but missing common variations' rather than the broad natural-term coverage of a 3.

The Engram scoping gives it a niche, but generic trigger phrases like 'reviewing changes' and 'starting substantial work' overlap with many general development skills, fitting 'Somewhat specific but could still overlap with similar skills'; it is not a 3 because the triggers are not distinct enough to rule out conflicts.
