The description names the domain (crypto options flow) and mentions some actions (track, identify institutional positioning and market sentiment), but doesn't list multiple concrete specific actions like analyzing Greeks, tracking block trades, monitoring open interest changes, etc.

Clearly answers both 'what' (track crypto options flow to identify institutional positioning and market sentiment) and 'when' (explicit trigger phrases and use-when clause provided).

Includes some relevant trigger phrases like 'track options flow', 'analyze derivatives', and 'check institutional', but misses common natural variations users might say such as 'whale activity', 'large trades', 'put/call ratio', 'options volume', 'smart money', or 'crypto derivatives'.

The crypto options flow niche is fairly specific, but terms like 'analyze derivatives' and 'check institutional' are broad enough to potentially overlap with general crypto analysis or traditional finance derivatives skills.

The skill is extremely verbose with extensive explanations of options concepts Claude already knows (put/call ratios, max pain, IV term structure). The error handling table, output section, and resources section are all padded well beyond what's necessary. The 'Understanding of options terminology' prerequisite is unnecessary for Claude.

The instructions reference specific CLI commands (e.g., `python options_flow.py btc --summary`) and bash patterns (`Bash(crypto:options-*)`), but no actual executable code is provided—just CLI invocations for a script that presumably exists somewhere. The steps are largely descriptive ('Calculate the aggregate put/call ratio') rather than providing concrete implementation code or API calls.

Steps are listed sequentially (1-10) but lack validation checkpoints. There's no feedback loop for verifying API connections succeed before proceeding, no checkpoint after data retrieval to confirm completeness, and no validation step before generating the final report. The error handling table exists but is separate from the workflow rather than integrated as checkpoints.

References `${CLAUDE_SKILL_DIR}/references/implementation.md` for the full implementation workflow and `${CLAUDE_SKILL_DIR}/config/crypto-apis.env` for credentials, which is good structure. However, no bundle files are provided to support these references, and the SKILL.md itself contains a large amount of detail (extensive output specs, error tables, resources) that could be split into reference files. The main file is quite long for an overview.
