Conciseness

The body is short and command-first with no explanation of concepts Claude already knows, but there is minor trimmable material: the "Use Cases" section ("Check when positions have upcoming earnings risk / Plan trades around earnings announcements / Build an earnings calendar for watchlist") largely restates the description, and the "Dependencies" section lists `pandas`/`yfinance` while the script actually imports `trading_skills`. This fits the 4 anchor 'Efficient; minor instances of over-explanation that could be trimmed' rather than 5, where every token would earn its place.

Actionability

The guidance is fully executable and copy-paste ready: "uv run python scripts/earnings.py SYMBOLS" with the SYMBOLS argument defined ("Ticker symbol or comma-separated list") and three concrete examples (single symbol, multi-symbol, portfolio). The output fields are enumerated so Claude knows what to expect. This matches the 5 anchor; 4 would require gaps in the executable guidance, and none are present.

Workflow Clarity

This is a simple, single-action, read-only skill and the single action is unambiguous (run one script with one argument), with a fallback note for missing `uv`/`pyproject.toml` ("replace `uv run python` with `python`"). Per the simple-skill exception, a single unambiguous action scores 5; no validation checkpoint is needed since the operation is non-destructive and non-batch.

Progressive Disclosure

The skill is a short, single-purpose document (~55 body lines) organized into clean sections (Instructions, Arguments, Output, Examples, Use Cases, Dependencies, Timezone), and its only bundle reference, `scripts/earnings.py`, exists at the referenced path — verified against the actual bundle structure. With no need for external reference files, this meets the 5-anchor condition for short simple skills with well-organized sections.

Specificity

"Get upcoming earnings dates with timing (before/after market) and EPS estimates" names multiple concrete capabilities (date retrieval, before/after market timing, EPS estimates) that comprehensively cover every field the skill outputs. It matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' rather than 4, since no output capability of the skill is missing.

Completeness

Both halves are explicit: 'what' is stated concretely ("Get upcoming earnings dates with timing (before/after market) and EPS estimates") and 'when' is stated with concrete trigger phrases ("Use when user asks about earnings dates, earnings calendar, when a company reports, or upcoming earnings"). This is a direct match for the 5 anchor; the 4 anchor would require a less explicit 'when' clause, which is not the case here.

Trigger Term Quality

"Use when user asks about earnings dates, earnings calendar, when a company reports, or upcoming earnings" covers the natural phrasings users would actually say, including synonyms (dates, calendar, reports, upcoming). This is comprehensive coverage in the pattern of the 5-anchor example; 4 would require noticeable missing natural terms, and none are apparent.

Distinctiveness Conflict Risk

The earnings-report/EPS-estimate niche is clearly distinct with dedicated triggers ("earnings calendar", "when a company reports") unlikely to fire for unrelated skills. Conflict risk with adjacent finance skills (quotes, news, dividends) is minimal because the triggers are earnings-specific, matching the 5 anchor 'Clear niche with distinct triggers; minimal conflict risk'.
