Investigate

When you need to understand how something works in an unfamiliar codebase, this skill does the legwork for you. It searches for relevant files, reads through implementations, and surfaces a direct answer with file paths and line numbers included. The output is formatted for Linear with collapsible sections, which is thoughtful if that's your workflow but a bit opinionated otherwise. Honestly, the real value is in having a structured approach to code research rather than just dumping a question into chat and hoping for coherence. It won't replace actually reading the code yourself for complex questions, but it's solid for quick orientation or when you're context switching between projects.

Files

Investigate

Research the codebase and provide a clear, direct answer to the question.

Approach

Search — Search the codebase for relevant files, functions, and patterns
Read — Read necessary files to understand the implementation
Gather context — Use tools as needed to collect comprehensive information
Answer — Provide a clear, direct answer using your findings

Answer Format

Present in Linear-compatible markdown
Use +++Section Name\n...\n+++ for collapsible sections with detailed information
Include code references with file paths and line numbers
For @mentions, use the Linear profile URL format from <assignee> context (e.g. https://linear.app/<workspace>/profiles/<username>)
Be complete but concise — answer the question directly without unnecessary preamble
