Conciseness

The ~25-line body contains zero explanations of concepts Claude already knows; every line is a rule, a trigger condition, or a verification check. This matches anchor 5 ('lean and efficient; every token earns its place').

Actionability

Rules are directive and concrete ("Update docs in the same PR as the code change", "Validate examples before publishing") and the verification checklist gives specific checks. However, no commands or examples show how to validate examples or execute the checks, so it falls short of anchor 5's copy-paste-ready guidance; well above anchor 3's incomplete/pseudocode level.

Workflow Clarity

This is a simple rule-set skill, not a sequential process: it has clear trigger conditions and an explicit verification checklist ("Endpoint names match server routes", "Command examples execute as documented"), so checkpoints are present rather than implicit. It lacks a stated order of operations, keeping it below anchor 5; it exceeds anchor 3 because the checklist provides real validation checkpoints.

Progressive Disclosure

Under 50 lines with no external content needed and no bundle files (no references/, scripts/, or assets/ exist); the three sections (When to Use, Alignment Rules, Verification) are well-organized. Per the rubric's simple-skill note, this qualifies for anchor 5.

Specificity

"Documentation alignment rules for Engram" names the domain and a single concrete action (aligning docs), but does not enumerate the specific actions the skill performs (e.g., updating docs in the same PR, validating examples). Fits anchor 3 (names domain and 1-2 concrete actions) better than anchor 4's 'several specific actions'.

Completeness

Explicitly answers both: what ("Documentation alignment rules for Engram") and when ("Trigger: Any code or workflow change that affects user or contributor behavior"). The trigger clause is labeled and more concrete than anchor 4's generic 'when', matching anchor 5's explicit what-and-when with concrete trigger conditions.

Trigger Term Quality

"Any code or workflow change that affects user or contributor behavior" plus "Documentation" give good natural keyword coverage. Missing common variations users would say (e.g., "update the docs", "README", "changelog"), so below anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Scoping to a named product ("Engram") establishes a clear niche with low conflict risk, but the broad trigger ("any code or workflow change") could overlap with other docs or maintenance skills. Mostly distinct with minor overlap risk, matching anchor 4.
