onboard-repo

onboard-repo is a skill for Claude Code from n24q02m/claude-plugins. It costs 38 tokens per session (1,606 once invoked), scanned A, a copy of onboard-repo, Apache-2.0.

A repository-orientation tool that indexes an unfamiliar codebase into a searchable knowledge graph and creates a map of its important parts.

In plain words
What is it for?
Use it when first opening a repository to identify entry points, heavily depended-on modules, risk hotspots, and the structure of its tests without modifying source code.
Why use it?
It gives an agent an initial understanding of a new project before answering questions or making changes, including where code starts, what modules are widely used, and where tests are located.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

onboard-repo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Onboard Repo

Take a codebase you have never seen and turn it into a queryable graph, then read the graph to produce an orientation map. Use this on first contact with a repository, before answering questions about it or changing anything in it.

Scope: this skill builds and reads a knowledge graph. It does not modify source files, CI configuration, or project conventions. The only files it creates are the graph database under .code-review-graph/ (already self-ignored) and, when you choose to add one, a .code-review-graphignore.

Command surface: run the local CLI through the coding harness shell. Examples use the installed better-code-review-graph command; from a source checkout, prefix it with uv run. No MCP mapping is required.

Steps

  1. Check what already exists with better-code-review-graph graph stats --repo-root "<path>". A non-empty graph can go directly to step 5; a missing-graph error means continue with a build.

  2. Decide the indexing scope before building:

    • Single repository: pass only --repo-root "<path>".
    • A repository that vendors or embeds others: add a .code-review-graphignore at the repo root (one fnmatch pattern per line, # for comments) so vendored trees, build output, and fixtures do not inflate the graph. Common additions: vendor/*, third_party/*, **/generated/*, **/*.min.js.
    • Several sibling repositories that call each other: federate them in one graph with --roots in step 3, then use impact-audit for cross-repo questions.

  3. Build the graph with better-code-review-graph graph build --full-rebuild --repo-root "<path>".

    • For a federated build: better-code-review-graph graph build --full-rebuild --repo-root "<path-a>" --roots "<path-b>". Each root is registered in the repo registry and its files are tagged with a repo_id, which later lets you scope any query with --repo "<repo_id>".
    • Parsing is Tree-sitter based and needs no language servers, toolchains, or compilation -- an unbuildable checkout still indexes.
