Conciseness

The 26-line body is lean and assumes Claude's competence: no concept explanations, no padding, and terse imperatives like "Confirm silently from context; do not interrogate the user" and "Never fabricate a provider's position." Every token carries instruction, matching the 'lean and efficient' anchor — there is nothing an intelligent reader would need trimmed.

Actionability

Guidance is mostly executable for an instruction-only skill: a concrete command to run (`${CLAUDE_PLUGIN_ROOT}/scripts/helpers/check-providers.sh`), a specific slash command to invoke with defined arguments, and concrete guardrails ('state the expected cost band from the CLAUDE.md cost table'). It falls short of 5 because the invocation format for /octo:debate, the composition of the 'standard Octopus banner', and what 'rounds' mean are left unspecified, and the referenced helper script is not present in this bundle to verify.

Workflow Clarity

The five steps are clearly sequenced with a pre-flight check (check-providers.sh before launch), an explicit conditional branch ('if only Claude is available... offer a single-model pro/con instead'), and error recovery ('If a seat fails, report the failure and continue with the remaining seats'). It is not 5 because the synthesis step's convergence check is a one-line summary without validation of round completion or output shape, leaving minor checkpoint gaps.

Progressive Disclosure

The skill is under 50 lines with well-organized sections (When to use / Steps / Guardrails) and no inlined content that belongs in a separate file, so it nearly earns the simple-skill 5. It drops to 4 because the sole external reference, `scripts/helpers/check-providers.sh`, is clearly signaled one level deep but is not present in the bundle (no scripts/ directory exists), so the reference cannot be resolved as structured.

Specificity

The description lists several concrete actions — "frame a decision as a multi-model debate", "picks sides, seats providers", "launches /octo:debate with a well-formed motion" — which names the domain and multiple specific capabilities. It is not 5 because coverage is incomplete (the synthesis/recommendation step and the cross-lab pairing rationale are absent), but it clearly exceeds the 3 anchor's '1-2 concrete actions'.

Completeness

The 'what' is clear (frame a debate, assign sides, seat providers, launch /octo:debate), but there is no 'Use when...' clause or equivalent trigger guidance anywhere in the description — only the bare 'When to use' exists in the body, which does not count here. Per the judging guideline, a missing explicit trigger clause caps completeness at 3; it is not 2 because the 'what' half is explicit and concrete rather than vague.

Trigger Term Quality

Relevant keywords exist ("decision", "debate", "multi-model", "providers", "/octo:debate") but common natural phrasings users would actually say — "second opinion", "pros and cons", "adversarial review", "X vs Y", "which should we pick" — are missing, and there are no synonyms or variations. This matches the 'some relevant keywords but missing common variations or synonyms' anchor rather than 4, since more than a few natural terms are absent.

Distinctiveness Conflict Risk

The niche is fairly distinct — "multi-model debate", "seats providers", and the specific command "/octo:debate" are unlikely to trigger for unrelated skills. It is not 5 because generic words like "decision" and "picks sides" could overlap with other decision-support or planning skills, giving minor overlap risk with closely related skills.
