Rank repository files by relevance to a task. Call this FIRST on a new task, before grepping or reading: it returns the top-K paths with scores and reasons. Follow up with redcon_compress on the top hits.

Lightweight repository map grouped by directory, filtered to the task's modules. Use to orient instead of ls -R or find; costs a few hundred tokens. For signatures, use redcon_repo_map.

Task-scoped compressed view of one file (signatures, imports and the relevant sections), typically 3-10x fewer tokens. Prefer this over reading a whole file; fetch the full file only if it is insufficient.

Regex search. scope='ranked' (default) limits matches to the task's relevant files; scope='all' covers the whole repo. Prefer over raw grep on large repositories.

Plan how to fit a set of files under a token budget, choosing a compression strategy per file. Use before reading several files at once; returns per-file token costs, strategies, and which to drop.

Search by AST pattern (ast-grep), not regex, so matches skip comments and strings. Needs ast-grep on PATH or redcon[ast_grep]; returns backend=unavailable otherwise so callers fall back to redcon_search.

Repo map: top ranked files plus their class and function signatures with line numbers, under a token budget. Use for code structure across many files at once. Degrades to a path-only listing without the redcon[symbols] extra.

Run a shell command, compress its output, and verify the compression against the M8 quality harness. Use instead of redcon_run when you want a structured pass/fail verdict on the compression.

Run a shell command and return its output compressed for LLM consumption (pytest, git diff/status/log, builds, coverage and more). Use instead of a raw shell when output may exceed a screenful; token caps are hard and failures keep their essential detail. DISABLED by default; set REDCON_MCP_ENABLE_RUN=1 to enable.
