Execute a shell command with intelligent output filtering. Detects command type and applies the optimal filter strategy to reduce token consumption while preserving all actionable information (errors, failures, changes).

Read a file with intelligent reduction. Modes: "full" (collapses blanks, licenses, imports), "signatures" (extracts declarations only), "relevant" (focus pattern with ±10 lines context).

Search for regex patterns in a directory with results grouped by file or match, deduplicated with [×N] prefix. Uses ripgrep when available, falls back to native recursive search.

Execute a test command and return structured, actionable output. Shows only failures by default (name, location, error, expected/received, truncated stack). Detects Jest/Vitest/pytest/cargo-test/go-test automatically.

Execute git operations with compact, optimized output. Supports: status (compact summary), diff (filtered hunks), log (one-line format), and action commands (commit/push/pull/add/branch with minimal confirmation).
