Conciseness

The body is mostly efficient as structured workflow steps, but includes explanations Claude already knows: 'RSI: Overbought (>70) or oversold (<30)', 'Reversal patterns (head and shoulders, double top/bottom)', and generic formatting/tone advice ('Use tables for financial data', 'Objective and balanced', 'Avoid hyperbole') that duplicates content in references/technical-analysis.md and adds no skill-specific value. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') rather than anchor 2, since there is no padded prose and the structure is sound — but the knowledge-duplication is more than 'minor', keeping it below anchor 4.

Actionability

As an instruction-only skill, it gives concrete guidance: exact search strings ('AAPL financial metrics 2024'), enumerated data to fetch, named quality sources, per-workflow reference reads, and defined output formats. It falls short of anchor 5 because some instructions remain high-level — 'Estimate fair value range' and 'Develop bull and bear cases' defer method entirely to references, and no filled-in example output or table is shown — matching anchor 4 ('mostly executable guidance; concrete code or commands with minor gaps').

Workflow Clarity

Four workflows are clearly sequenced with 'When to Use' preconditions and stepwise numbering, and workflows compose (the comprehensive report reuses the fundamental and technical workflows). It matches anchor 4 ('clear sequence with most checkpoints present; minor validation gaps'): the only validation checkpoint is 'Always verify data recency (prefer data from last quarter)', with no explicit cross-check of conflicting data between sources or verify-completeness step before writing the report. It is above anchor 3, which requires checkpoints to be missing or implicit — the recency check is explicit — and the operations are read-only, so no destructive/batch validation cap applies.

Progressive Disclosure

The body is an overview plus workflows that point to four real, one-level-deep reference files (all verified present in references/: technical-analysis.md, fundamental-analysis.md, financial-metrics.md, report-template.md), each signaled inline at the point of need ('Read references/technical-analysis.md for indicator definitions') and summarized in a 'Reference Files' section with When/Contains entries, with no nested references. This matches anchor 5 ('Clear overview with well-signaled one-level-deep references; content appropriately split; easy navigation').

Specificity

Lists multiple concrete capabilities with parenthetical specifics — 'fundamental analysis (financial metrics, business quality, valuation), technical analysis (indicators, chart patterns, support/resistance), stock comparisons, and investment report generation' — giving comprehensive coverage of what the skill does. It fits the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and is above anchor 4, which expects minor gaps in coverage; no capability area is missing.

Completeness

Explicitly answers both questions: the 'what' via the enumerated capability list, and the 'when' via a concrete 'Use when user requests...' clause with example trigger phrases. This matches anchor 5 ('Clearly and explicitly answers both what AND when with concrete trigger phrases'); anchor 4 would require the 'when' to be less explicit or specific, which it is not.

Trigger Term Quality

Includes natural phrases users would say — 'analyze AAPL', 'compare TSLA vs NVDA', 'give me a report on Microsoft', 'evaluation of financial metrics', 'technical chart analysis', 'investment recommendations' — which is good keyword coverage with concrete example queries. It falls short of anchor 5 because common variations like 'should I buy X', 'is X overvalued', or 'financials' are absent, matching anchor 4 ('a few natural terms missing') better than the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The niche is clear — US stock tickers, American stocks, ticker examples like AAPL/TSLA/NVDA — with triggers ('analyze AAPL', 'compare TSLA vs NVDA') that are unlikely to fire for unrelated skills. It matches anchor 5 ('Clear niche with distinct triggers; minimal conflict risk'); overlap risk with generic finance or search skills is minimal.
