86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a well-structured, highly actionable workflow with executable code and genuinely non-obvious domain knowledge (report timing, reaction windows, YoY column availability), and it properly delegates API detail to a real one-level-deep reference file. The only weaknesses are minor: a clunky environment-check block and missing error-recovery guidance for bad tickers or empty data.
Suggestions
Replace the '!`python3 -c ...`' environment-status block in Step 1 with a plain instruction (e.g., check for yfinance and pip-install if missing) — the current construct is non-standard and adds tokens without adding clarity.
Add a brief error-recovery note in Step 2 or 3 for failure cases: an unrecognized ticker or empty earnings_history/get_earnings_dates(), stating what to tell the user or how to fall back.
Trim redundant phrasing such as 'If already installed, skip to the next step' to tighten token efficiency toward the lean 5-anchor.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and adds only non-obvious knowledge (e.g., 'earnings_history is indexed by fiscal quarter-end, not by announcement date'; the 16:00 after-close vs before-open reaction windows), with no padding about what yfinance or EPS are. It falls short of the 5 anchor because of minor trimmable material: the awkward '!`python3 -c ...`' environment-status block in Step 1 and the slightly redundant 'If already installed, skip to the next step' line. | 4 / 5 |
Actionability | The guidance is fully executable: copy-paste-ready Python for fetching data, a working earnings_reaction() function handling the after-close/before-open split, a table of key fields per data source, and explicit direction for edge cases ('If reaction_pct is None, ... say the regular-session reaction is still pending'). It matches the top anchor — the common cases are covered by specific, runnable code. | 5 / 5 |
Workflow Clarity | The five-step sequence (ensure yfinance → gather data → find report and measure reaction → build recap → respond) is clear, and Step 1's install check plus Step 3's None-reaction fallback act as checkpoints. It falls short of 5 because some validation gaps remain: no guidance for what to do when the ticker is invalid or earnings_history/get_earnings_dates() returns empty data — error recovery beyond the pending-reaction case is not addressed. | 4 / 5 |
Progressive Disclosure | The SKILL.md is a workflow-level overview with detailed API signatures correctly split into a single one-level-deep reference ('references/api_reference.md — Detailed yfinance API reference...'), which exists and matches that description. The reference is well-signaled with guidance on when to read it ('Read the reference file when you need exact method signatures or to handle edge cases'), matching the top anchor for clean navigation. | 5 / 5 |
