Understand Quickly tools (4)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • find_graph_for_repo

    Look up a registry entry by `id` ("owner/repo") or `github_url` (https or ssh form, with optional .git/branch/path). Returns graph_url + drift metadata, or {found:false, suggestions} with up to 5 fuzzy-matched ids.

  • get_graph

    Fetch and return the parsed knowledge graph JSON for a registry entry by id.

  • list_repos

    List entries in the understand-quickly registry. Optional filters: format, tag, status.

  • search_concepts

    Search aggregated concept terms across the registry. By default reads the precomputed stats.json (single GET, cached 60s) and returns matching terms with sample entry ids. If `id` is given, falls back to a single-graph node search. If stats.json is unavailable, falls back to a capped cross-graph node fan-out.

🧠 understand-quickly

A public, machine-readable registry of code-knowledge graphs.

Point AI agents at any indexed repo and they get a current, schema-validated graph — one URL, one fetch.

It's a public directory of "map files" for codebases. Each entry points at a JSON file (a knowledge graph or context bundle) that describes a project's structure — files, functions, modules, how they connect — in a shape that AI tools can read in one network request.

If you're a project maintainer, you can add your repo so AI assistants can understand it instantly. If you're an AI agent or tooling developer, you can fetch any indexed graph by URL with no auth and no SDK.

Shortened. The full README is on GitHub.
