build-graph

A guide for building or updating a repository’s persistent knowledge graph, which records relationships between code elements. It stores the graph in a SQLite database, a file-based database format, inside the repository.

In plain words
What is it for?
It is for creating the graph for the first time, updating it incrementally, checking repository statistics, and reporting parsed files, code relationships, detected languages, and errors.
Why use it?
It initializes the map used by code-review tools and keeps that map current after changes, refactoring, or branch switches.

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

build-graph 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 2d 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.

What it actually says

Build Graph

Build or incrementally update the persistent code knowledge graph for this repository.

Steps

  1. Check graph status by calling the list_graph_stats_tool MCP tool.

    • If the graph has never been built (last_updated is null), proceed with a full build.
    • If the graph exists, proceed with an incremental update.
  2. Build the graph by calling the build_or_update_graph_tool MCP tool:

    • For first-time setup: build_or_update_graph_tool(full_rebuild=True)
    • For updates: build_or_update_graph_tool() (incremental by default)
  3. Verify by calling list_graph_stats_tool again and report the results:

    • Number of files parsed
    • Number of nodes and edges created
    • Languages detected
    • Any errors encountered

When to Use

  • First time setting up the graph for a repository
  • After major refactoring or branch switches
  • If the graph seems stale or out of sync
  • The graph auto-updates via hooks on edit/commit, so manual builds are rarely needed

Notes

  • The graph is stored as a SQLite database (.code-review-graph/graph.db) in the repo root
  • Binary files, generated files, and patterns in .code-review-graphignore are skipped
  • Supported languages: Python, TypeScript/JavaScript, Vue, Go, Rust, Java, Scala, C#, Ruby, Kotlin, Swift, PHP, Solidity, C/C++
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

build-graph is a skill published in the GitHub repository tirth8205/code-review-graph (31,071 stars, last pushed 5d ago), licensed MIT. It adds 27 tokens to every session and 356 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
