Conciseness

The body is dense with operational rules and explains no concepts Claude already knows, matching anchor 4 ("efficient; minor instances of over-explanation that could be trimmed"). It is not anchor 5 because some invariants are stated redundantly — "Never run ON for them" vs "do not execute the ON wrapper on the user's behalf", and the no-renewal rule appears both as "Reuse ON without renewing expiry" and "Neither repeated session ON nor repeated key-gate ON silently renews a lifetime" — and not anchor 3 because there is no genuinely unnecessary explanation.

Actionability

Guidance is mostly executable with concrete commands — "python3 scripts/power.py status TARGET", "python3 scripts/session.py status TARGET", "bash scripts/fullpower-on.sh [seconds]", "luffy fullpower on TARGET [DURATION] [--password]" — plus an explicit three-way outcome taxonomy for reporting. It stops short of anchor 5 because several referenced scripts (power.py, session.py) and reference files resolve only inside the sibling luffy-arm bundle, not this one, leaving minor gaps for an agent working from this skill alone.

Workflow Clarity

The numbered 1–5 sequence has explicit validation checkpoints (check status before re-arming, proceed only after verified OFF, repeat the host-first status check after the user runs the command) and error-recovery branches for UNKNOWN and OFF states, matching anchor 5's "clear sequence with explicit validation steps; feedback loops for error recovery". Anchor 4's "minor validation gaps" understates the checkpoint coverage present.

Progressive Disclosure

References to the sibling skill's Full-power mode section, references/targets.md, references/user-sessions.md, and scripts are clearly signaled and only one level deep, and the bundle's one script (scripts/fullpower-on.sh) genuinely backs the body's invocation. Anchor 4 fits: good structure with minor gaps, since most referenced paths resolve outside this bundle and are plain paths rather than links, so navigation depends on the sibling skill being installed.

Specificity

The description names several concrete actions — "turn on, enable, open, or arm luffy-arm full-power mode", "Check layered host status first and reuse an already-ON dedicated gate", "gate state and effective ADMIN_USER access are distinct", "The agent never loads the key for them" — which sits at anchor 4. It falls short of anchor 5 because several statements are behavioral constraints on a narrow companion operation rather than a comprehensive list of capabilities, and above anchor 3 because far more than 1-2 concrete actions are named.

Completeness

It explicitly answers both questions: "Use when the user explicitly asks to turn on, enable, open, or arm luffy-arm full-power mode" (a maximally explicit when with concrete trigger phrases) and a concrete what (check layered host status first, reuse an already-ON gate, distinguish gate state from ADMIN_USER access, never load the key). This matches anchor 5; anchor 4's caveat that the 'when' could be more specific does not apply.

Trigger Term Quality

Trigger coverage is comprehensive with natural synonyms and even bilingual variants: "turn on full power", "enable full-power", "打开 full power", "开启全功率模式", plus the verbs turn on/enable/open/arm. This matches the anchor-5 pattern of comprehensive natural-term coverage with synonyms; anchor 4 ("a few natural terms missing") does not apply.

Distinctiveness Conflict Risk

Direction-specific triggers ("turn on", "enable", "开启") carve a clear niche distinct from the sibling luffy-arm and fullpower-off skills, so conflict risk is minimal but not zero — it is one of a family of closely related companion skills sharing the same domain vocabulary. Anchor 4 ("mostly distinct; minor overlap risk with closely related skills") is the best fit; anchor 5 would require no such sibling-family overlap.
