Conciseness

Mostly efficient — no explanations of concepts Claude already knows — but it could be tightened: the save-path rule is repeated in Step 3.3, the Output table, and the Important Notes section ("Must not save directly to the project root" appears twice), and the ASCII Architecture diagram restates the Workflow phases. This fits 'mostly efficient but includes some unnecessary explanation or could be trimmed'; not 4 because the duplication is more than minor.

Actionability

Fully executable for an orchestration skill: verbatim copy-paste agent prompts with explicit subagent_type and requirements, an event-classification table, a complete report template, and exact file-naming and save paths. This matches 'fully executable; copy-paste ready... specific examples cover the common cases'.

Workflow Clarity

A clear three-phase numbered sequence with an input checkpoint ("If not provided, ask the user") and a closing Quality Checklist covering probabilities, logic, and save path. Not 5 because in-flight validation is only implicit — there is no step to verify the scenario-analyst output (e.g., probabilities sum to 100%) before invoking strategy-reviewer or integrating; the checklist runs only at the end.

Progressive Disclosure

SKILL.md is a clear orchestrator overview; the three referenced files (headline_event_patterns.md, sector_sensitivity_matrix.md, scenario_playbooks.md) all exist with substantive content (218–321 lines each), are one level deep, are loaded conditionally by event type in Step 1.3, and are summarized with one-line descriptions in the Resources section. This matches the top anchor: well-signaled one-level-deep references with easy navigation.

Specificity

The description lists multiple concrete actions — "analyzes 18-month scenarios from a news headline", "Runs the primary analysis with the scenario-analyst agent", "obtains a second opinion with the strategy-reviewer agent", and specifies report contents ("1st/2nd/3rd-order impacts, recommended stocks, and a critical review"). This matches the anchor for multiple specific concrete actions with comprehensive coverage; the only mild padding is the word "comprehensive", which is not enough to drop it to 4.

Completeness

It explicitly answers both questions: the 'what' is the multi-action description above, and the 'when' is the explicit "Triggers:" clause with concrete trigger phrases — equivalent explicit trigger guidance, so the missing-'Use when' cap at 3 does not apply. Not 4 because the when-clause is already explicit and concrete rather than merely improvable.

Trigger Term Quality

The Triggers list — "news analysis, scenario analysis, 18-month outlook, medium-to-long-term investment strategy" — covers natural phrases a user would say, plus a concrete example invocation. A few natural variants are missing (e.g., "stock recommendations", "what does this headline mean for the market"), so it fits 'good keyword coverage; a few natural terms missing' rather than the comprehensive-synonyms anchor at 5.

Distinctiveness Conflict Risk

The niche is clear and narrow — 18-month investment scenario analysis from news headlines with a dual-agent (analyst + reviewer) pipeline — with distinct triggers unlikely to fire for unrelated skills. Minimal conflict risk matches the top anchor.
