Ranked content search over a text corpus you point it at, using BM25 (via xhluca/bm25s). Corpus-agnostic: cloned repos, project knowledge stores, uploaded files and archives, any local directory. In-memory BM25 index per invocation, with a session-local disk cache for repeat runs against the same corpus. Use for "rank these documents", "search this corpus", "which files are most about X", "find content about Y", or any multi-word concept query against a known body of text where grep would…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# bm25 Ranked content search over any text corpus. One CLI, in-memory BM25 index per process, with a session-local disk cache so repeat invocations against the same corpus load in tens of milliseconds instead of rebuilding. ## Setup ```bash uv pip install --system --break-system-packages bm25s ``` Install is sub-second on a warm uv cache. That's the entire dependency. ## Usage ```bash BM25=/mnt/skills/user/bm25/scripts/bm25.py # Local directory python3 $BM25 ./repo 'csrf middleware' # Multiple queries against the same in-memory index (build once, query many) python3 $BM25 ./repo 'csrf middleware' 'session backend' 'queryset filter' # Cloned GitHub repo via tarball (one HTTP call) python3 $BM25 'github.com/django/django' 'atomic transaction' python3 $BM25 'github.com/django/django@stable/5.0.x' 'atomic transaction' # Project knowledge or uploads python3 $BM25 project 'RAG scaling laws' python3 $BM25 uploads 'tax loss harvesting' # Filters python3 $BM25 ./repo 'auth flow' --exclude 'tests/*' --exclude '*/tests/*' python3 $BM25 ./repo 'config' --include '*.py' --include '*.toml' # Interactive (REPL — single corpus, many queries) python3 $BM25 ./repo --interactive …

How to install
mdr add oaustegard/claude-skills/bm25@sha256:4199603c37d75f39The line at the top of this page pins the label v0.2.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
