- SKILL.md covers Steps, When to Use and Notes
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The agent starts by asking for graph statistics; if `last_updated` is empty, the graph has never been built. A first build, or a request with the argument `full`, triggers a complete rebuild, and any other call performs an incremental update. The agent then reports the returned status (ok, partial or error) and summary.
Manual builds suit first setup, a branch switch, a large refactor or a graph that looks stale; hooks installed by `code-review-graph install` already refresh it after edits and before commits, so they are rarely needed. The graph is stored in `.code-review-graph/graph.db`, binary files, dependency and build directories and patterns in `.code-review-graphignore` are skipped, and supported languages can be listed through the docs tool.
When your agent uses it
- Setting up the code-review graph in a repository for the first time
- Refreshing the graph after switching branches or a large refactor
- Rebuilding the graph from scratch when it looks stale
Example prompts
- “Build the code review graph for this repo.”
- “I just rebased onto main, so do a full rebuild of the graph.”
- “Update the knowledge graph and tell me whether the build was partial.”
Requirements
- code-review-graph installed, with its MCP tools available
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Call list_graph_stats_tool. If last_updated is null, the graph has never been built.
- For a first build, or when the argument is full, call build_or_update_graph_tool(full_rebuild=True). Otherwise call…
- Report the response: status (ok, partial or error) and summary.
What it can do on your machine
Read from SKILL.md and the folder at commit 6b12d11. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Code Review Graph Builder loads about 295 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 128 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Build Graph
Build or incrementally update the knowledge graph for this repository.
Steps
- Call
list_graph_stats_tool. Iflast_updatedis null, the graph has never been built. - For a first build, or when the argument is
full, callbuild_or_update_graph_tool(full_rebuild=True). Otherwise callbuild_or_update_graph_tool()for an incremental update. - Report the response:
status(ok,partialorerror) andsummary.
When to Use
- First set-up of a repository, or after a branch switch or large refactor.
- When the graph looks stale. Hooks installed by
code-review-graph installrun an update after each edit and before each commit, so manual builds are rarely needed.
Notes
- The database is
.code-review-graph/graph.dbin the repository root. - Binary files, dependency and build directories, and patterns in
.code-review-graphignoreare skipped. - For the list of supported languages call

A first build, or a request with the argument `full`, triggers a complete rebuild, and any other call performs an incremental update.
When should I use Code Review Graph Builder?
Code Review Graph Builder fits situations like: setting up the code-review graph in a repository for the first time; refreshing the graph after switching branches or a large refactor; rebuilding the graph from scratch when it looks stale.
How do I install Code Review Graph Builder in Claude Code?
Run `npx skills add tirth8205/code-review-graph --skill build-graph -a claude-code`. Or copy the skill folder (skills/build-graph in tirth8205/code-review-graph) into .claude/skills/build-graph in your project. Claude Code loads it when a task matches its description.

Can I use Code Review Graph Builder in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tirth8205/code-review-graph --skill build-graph -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/build-graph, .gemini/skills/build-graph, .github/skills/build-graph and .opencode/skills/build-graph in your project.
What does Code Review Graph Builder need to run?
SKILL.md names no scripts, command-line tools or credentials: Code Review Graph Builder is instructions for the agent only. Our summary lists: code-review-graph installed, with its MCP tools available.
Does Code Review Graph Builder access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
