Rank repository files by relevance to a task using keyword and import-graph signals. Call this FIRST on any new task, before searching or reading files: it replaces guessing paths, broad grep sweeps, and directory listings. Returns the top-K paths with scores and reasons; follow up with redcon_compress on the top hits instead of reading them whole.

Lightweight repository map grouped by directory, filtered to modules relevant to the task. Use when orienting in an unfamiliar repo instead of ls -R, find, or reading READMEs; costs a few hundred tokens. For actual code structure (signatures), use redcon_repo_map instead.

Task-scoped compressed view of one file: signatures, imports and the sections relevant to the task, typically 3-10x fewer tokens than the raw file. Default to this INSTEAD of reading a whole file; fetch the full file only if the compressed view turns out to be insufficient.

Regex search over the repository. scope='ranked' (default) searches only the files relevant to the task, so matches come pre-filtered by relevance instead of drowning you in hits; scope='all' covers the whole repo. Prefer this over raw grep on large repositories.

Plan how to fit a set of files into a token budget, choosing a compression strategy per file. Use BEFORE reading several files at once, whenever their combined size could blow the context: returns per-file token costs, chosen strategies, and which files must be dropped to stay under the budget.

Search code by AST pattern (ast-grep), not regex. Patterns like class $NAME { $$$ } match real class declarations and skip text occurrences inside comments / strings. Available when ast-grep is on PATH or redcon[ast_grep] is installed; returns backend=unavailable otherwise so callers can fall back to redcon_search.

Repo map: top ranked files plus their class/function signatures with line numbers, fitted under a token budget. Use when you need code structure across many files at once - one call replaces opening files one by one to learn their shape. Unlike redcon_overview it emits actual signatures, not just paths. Degrades to a path-only listing when the redcon[symbols] extra is missing rather than failing.

Run a shell command, compress its output, and verify the compression against the M8 quality harness (must-preserve patterns, reduction floor, determinism). Use this instead of redcon_run when you want a verdict before consuming the compressed bytes - the response is small and the verdict is structured.

Run a shell command and return its output compressed for LLM consumption via schema-aware compressors (pytest, git diff/status/log, builds, coverage, kubectl and more). Use INSTEAD of a raw shell whenever output may exceed a screenful - test runs, diffs, logs. The token caps are hard guarantees, and failures keep their essential detail (failing test names, error lines). DISABLED by default because it executes commands; set REDCON_MCP_ENABLE_RUN=1 on the server to enable it.
