Field counts come from the latest full-catalog snapshot. A resource can belong to several fields and platforms.
Use this skill when writing messages in async channels (Slack, GitHub issues, email threads) where the reader may not have context and cannot ask follow-up questions immediately.
Use this skill when writing any explanation, documentation, or response that will be read by someone else. Match vocabulary, depth, and format to the audience's expertise level before writing.
Use this skill when writing documentation, READMEs, technical specs, runbooks, or any text that explains a system or process to other engineers. Apply before writing any developer-facing document.
Use this skill when drafting emails, Slack messages, announcements, or any external/internal communication. Apply professional structure and appropriate tone before writing any message.
Use this skill when conducting research on a topic from scratch — literature review, competitive analysis, technical due diligence, or fact-finding. Apply before starting any open-ended research task.
Use this skill when summarizing progress on an ongoing project or multi-step task. Give a clear, scannable status report whenever asked for an update or at the end of a work session.
Use this skill when writing SQL queries — selects, joins, aggregations, window functions, or schema modifications. Apply whenever SQL is needed to ensure correctness, safety, and performance.
Use this skill when exploring an unfamiliar codebase, tracing code paths, or answering questions about how the system works. Read before writing, and build a mental model of the architecture before making changes.
Use this skill when implementing a new feature or fixing a bug. Write or update tests before marking the task done. Never consider code complete without verifying it works through automated tests.
Use this skill when diagnosing a bug, unexpected behavior, test failure, or any situation where code does not behave as expected. Follow a structured debugging process instead of randomly changing code.
Use this skill when implementing any endpoint, form handler, CLI tool, or function that accepts external input. Validate and sanitize all untrusted data before processing — never assume input is safe.
Use this skill when implementing authentication (login, token issuance) or authorization (access control, permissions). Apply whenever the task involves login flows, JWT, OAuth2, session management, or RBAC.
