Use FIRST for any question about code in a folder semlith has indexed — where X is (semlith_search), who calls it (semlith_neighbors), what breaks if it changes (semlith_impact), every line matching a string or regex (semlith_search exact: true), what a PDF, Word, PowerPoint or Excel file says — before grep, rg, find, cat or Read. Skip only for git history and the exact read right before an edit.
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
# semlith
The `semlith_*` MCP tools hold a pre-built index of the folders semlith covers:
chunks, embeddings, symbols and call edges. One call returns the lines that bear
on the question with a `path:line` you can cite.
## Pick the tool by the question
| The question | Call |
|---|---|
| Where is X? / how does X work? / which files handle X? | `semlith_search {query}` |
| Every line matching a string or regex (every TODO) | `semlith_search {query, exact: true}` |
| Who calls X? / every call site of X | `semlith_neighbors {name}` |
| What breaks if X changes? | `semlith_impact {name}` |
| This span / this whole function | `semlith_read {target}`: `path:start-end` or a symbol |
| Where are these defined? | `semlith_symbol {names: [...]}`, up to 20 |
| A span plus its callers and callees in one call | `semlith_brief {question}` |
| What is in this directory? | `semlith_files {tree: true}` |
| What does this PDF, Word, PowerPoint, Excel or EPUB file say? | `semlith_search {query, ext: ["pdf"]}`, then `semlith_read` |
**Documents.** semlith indexes PDF, Word, PowerPoint, Excel, OpenDocument, EPUB
and HTML as text. Grep and Read see those files' bytes, not their words: answer
…Read the whole file at its exact version.
How to install
mdr add semlith/semlith/semlith@sha256:0dd2e45f7f8903c9The line at the top of this page pins the label git:20261002.ad323e6, 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.
