Conciseness

The body is dense, non-obvious project policy with no basic-concept padding — every section states rules Claude could not infer. Minor trimmable material keeps it below the lean anchor: the dated "2026-06-17 incident (29 SPECs wrongly flagged...)" anecdote and parenthetical cross-reference chatter like "(CLAUDE.local.md §WARN)" are padding-adjacent, and the time-sensitive date is not placed in a deprecated/old-patterns section.

Actionability

Guidance is fully concrete and executable: exact commands ("go test ./...", "-count=1", "-race", "golangci-lint run"), exact file paths ("internal/config/envkeys.go", "internal/config/defaults.go"), a copy-paste "ToolSearch(query: \"select:AskUserQuestion,TaskCreate,...\")" pattern, the retained-agent whitelist, and a concrete per-spawn "Agent(subagent_type: \"general-purpose\", tools: ..., prompt: ...)" template covering the common delegation case.

Workflow Clarity

The TRUST 5 gates table functions as an explicit validation checklist ("Every change must pass all five dimensions before completion" with per-pillar failure actions), and "After fixing any test, run the FULL suite" is a real feedback loop. However, the skill is a multi-topic reference rather than a sequenced process, and error-recovery loops (what to do when a gate fails beyond the one-word failure action) are only implicit, so the full sequence-with-recovery anchor is not met.

Progressive Disclosure

The body is a well-sectioned overview that appropriately defers bulk detail (archived agent names, the migration table, the blocker report format) to one-level-deep referenced paths, with a Cross-References section for navigation. But the bundle ships no references/ files at all — the deferred content lives in external repo paths (".claude/rules/moai/...") that cannot be verified as part of the skill, leaving organization gaps against the clear-well-signaled-references anchor.

Specificity

The description enumerates concrete, specific coverage areas — "Covers TRUST 5 gates, Go test isolation (t.TempDir, no OTEL env in parallel tests), hardcoding-prevention rules (env constants in envkeys.go, thresholds in defaults.go), the AskUserQuestion orchestrator-only boundary, the deferred-tool preload rule, the archived-agent rejection contract, and verification-claim integrity" — leaving little ambiguity about scope. This matches the comprehensive-coverage anchor, exceeding the 'several specific actions; minor gaps' level below.

Completeness

Both what and when are explicit: the what is the enumerated best-practices coverage list, and the when is "Loaded by the specialists when authoring or reviewing moai-adk-go code" — concrete, third-person trigger guidance with named agents. This clears the missing-'Use when' cap and matches the explicit what-and-when-with-triggers anchor.

Trigger Term Quality

Keywords like "moai-adk-go", "TRUST 5", "t.TempDir", "envkeys.go", "AskUserQuestion", "archived-agent", "verification-claim" give good domain-keyword coverage for the target audience. They are jargon tokens rather than natural user phrasings and lack synonyms or common variations, so the comprehensive-synonyms anchor (5) is not met but the good-coverage-with-few-missing anchor fits.

Distinctiveness Conflict Risk

The description is anchored to a highly specific niche — "moai-adk-go best-practices reference for the 4 harness specialists (cli-template-specialist, quality-specialist, workflow-specialist, hook-ci-specialist)" — with distinct triggers unlikely to fire for unrelated skills. Minimal conflict risk with any other skill.
