What problem does it solve? Getting accurate answers about APIs, libraries, or technical topics usually means interrupting your work to read documentation yourself, or trusting secondary sources that may be outdated or wrong. This Skill delegates that reading to a background agent that consults primary sources directly. ## Core Features & Use Cases - Primary-source investigation: Traces every claim back to official docs, source code, specs, or first-party APIs rather than blog posts or summaries. - Background execution: Runs the research as a background agent so you can keep working while it reads. - Cited Markdown output: Writes findings to a single Markdown file with a source citation for each claim, saved where the repo already keeps such notes. - Use Case: Ask how a specific API endpoint behaves; the agent reads the official documentation and source code, then saves a cited summary into your repo's notes directory. ## Quick Start Research how the Stripe API handles idempotency keys and save the findings as a Markdown note in this repo.
