Conciseness

The body is lean and assumes competence: a one-line command, terse argument list, and an output schema with no concept explanations. Two minor trims exist — the 'Use Cases' section repeats trigger phrasing already covered by the description, and 'Dependencies' duplicates the frontmatter's dependency list — so it sits just below the 'every token earns its place' anchor.

Actionability

"uv run python scripts/insider_trading.py SYMBOLS [--days DAYS]" is a fully executable command (verified: the script exists with exactly this CLI), with a python fallback note, documented arguments including default (90 days) and multi-symbol examples ('NVDA' or 'NVDA,PLTR,GOOG'), and a described JSON output shape. Copy-paste ready and covers the common cases.

Workflow Clarity

This is a simple single-task skill (under 50 lines), and the single action is unambiguous: run the script with symbols and optional --days, then read the JSON output. The operation is read-only fetching (not destructive or state-changing), so no validation checkpoints are required, and the simple-skill exception applies cleanly.

Progressive Disclosure

The skill is a short, single-file overview with well-organized sections (Instructions, Arguments, Output, Dependencies, Timezone) and no content that warrants separate reference files. Its one bundle path, scripts/insider_trading.py, is real, correctly referenced, and one level deep — matching the guideline that a small skill with no external references scores 5.

Specificity

"Get insider trading activity (SEC Form 4 filings) for one or more stocks" names the domain and the concrete deliverable (Form 4 activity for single or multiple symbols), but only offers one generic action ("get... activity") — closer to the 'names domain and 1-2 concrete actions' anchor than the level-4 'lists several specific actions' anchor. It does not enumerate what the output contains (transactions, net sentiment, buy/sell ranking), which would be needed for 4.

Completeness

The "what" is explicit ("Get insider trading activity (SEC Form 4 filings) for one or more stocks") and the "when" is explicit with multiple concrete trigger phrases ("Use when user asks about insider buying/selling, executive transactions, insider sentiment, or Form 4 activity"). Both halves are directly stated, matching the level-5 anchor; level 4 would require the 'when' to be less specific than this.

Trigger Term Quality

"insider buying/selling", "executive transactions", "insider sentiment", and "Form 4 activity" are natural phrases users would say, giving good keyword coverage. A few common variations are missing (e.g., 'insider trades', 'SEC filings', 'insider transactions' — though 'executive transactions' partially covers it), which keeps it below the comprehensive level-5 anchor.

Distinctiveness Conflict Risk

Insider trading / Form 4 is a clear niche with distinct triggers, but "insider sentiment" and the multi-symbol stock scope create minor overlap risk with closely related trading/finance skills (the skill even depends on a "trading-skills" suite). This fits 'mostly distinct; minor overlap risk' slightly better than the minimal-conflict level-5 anchor.
