Conciseness

The ~35-line body is lean and directive throughout: one-line purpose ("Fetch current stock data from Yahoo Finance"), a single runnable command with a practical uv fallback note, a compact output-field list, and short presentation rules ("Highlight significant moves (>2% change)"). It explains nothing Claude already knows and contains no padded sections, matching 'every token earns its place'.

Actionability

The command `uv run python scripts/quote.py SYMBOL` is copy-paste ready with explicit substitution guidance ("Replace SYMBOL with the requested ticker (e.g., AAPL, MSFT, TSLA, SPY)"), the referenced file scripts/quote.py exists in the bundle, the environment fallback for missing `uv` is stated, and the exact output fields are enumerated. This covers the common cases fully, matching the anchor-5 executable example.

Workflow Clarity

This is a simple, single-task skill (run the script, present the output) and the single action is unambiguous, including what to do with the result ('Present the data in a readable format. Highlight significant moves'). The operation is read-only, so no validation checkpoint is required and the destructive-operation cap does not apply.

Progressive Disclosure

The body is well under 50 lines with clean sections (Instructions, Output, Dependencies, Timezone) and no content that warrants offloading to reference files. The one bundle file (scripts/quote.py) is correctly referenced from the body and the Dependencies section accurately names the required package, so structure and navigation are appropriate for the bundle.

Specificity

The description names one concrete action ("Get real-time stock quote") and enumerates specific returned metrics ("price, volume, change, market cap, and 52-week range"), which is concrete and domain-anchored. It stops short of a 5 because it omits outputs the skill actually provides (e.g., P/E ratio, dividend yield, average volume), leaving minor gaps in coverage; it is well above a 3 because the enumerated data fields go far beyond '1-2 concrete actions'.

Completeness

It explicitly answers both parts: what ("Get real-time stock quote with price, volume, change, market cap, and 52-week range for any ticker symbol") and when ("Use when user asks about current stock price, quote, or basic stock info") with concrete trigger phrases. This matches the anchor-5 example structure exactly, and clearly exceeds anchor 4 since the 'when' clause is explicit and specific rather than general.

Trigger Term Quality

Natural trigger phrases are present: "current stock price", "quote", "basic stock info", plus "ticker symbol" in the what-clause. A few natural variations users might say (e.g., 'share price', 'how is a stock doing', 'market data') are missing, matching the anchor 'good keyword coverage; a few natural terms missing' rather than the comprehensive synonym coverage of a 5.

Distinctiveness Conflict Risk

"real-time stock quote" and "ticker symbol" carve out a clear niche with distinct triggers; the scope (current quote data, not analysis, portfolios, or historical research) is unambiguous. Conflict risk with other skills is minimal, matching the anchor-5 example's clear-niche profile.
