Flight Price Advisor with Trend Chart for developer

This skill appears to implement the charting functionality it claims, but there are important inconsistencies and operational risks to review before installing or enabling it: 1) Credentials: The registry lists no required environment variables, yet the SKILL.md and docs require a SerpAPI key (and example config files reference OpenAI and flyai keys). Do not commit API keys into repo files (price/config.json) — prefer environment variables or a secrets vault. Remove any unnecessary keys (e.g., OpenAI) from shared config if they are not required. 2) Persistent data collection: The project suggests adding server code to store every flight search into price/data/price-history and to run scheduled collectors. That will persist user search results and increase outbound API usage and storage. Confirm retention policies, where files are stored, access controls, and legal/privacy considerations before enabling. 3) Cron and rate limits: If you enable automated collection, verify SerpAPI quotas and costs and throttle collection to avoid accidental overuse. 4) Scope-check the code: Review the server snippets and any omitted code carefully for endpoints, secrets handling, or unexpected network calls. Ensure the skill only calls SerpAPI (or other intended APIs) and does not post data to unknown external endpoints. 5) Hardening suggestions: store keys in environment variables or a secrets manager; do not check config files with keys into version control; restrict the data directory permissions; add logging and retention limits; consider requiring explicit opt-in before any data collection starts. If you need, I can: (a) list exact files/lines where credentials are referenced, (b) suggest safer config patterns and example env-var based configs, or (c) produce a checklist for reviewing the server-side snippets before deployment.
