A set of rules for using a local semantic code graph to answer structural questions about a codebase. The graph connects functions, symbols, files, callers, and dependencies.

Use it to find callers, assess change impact, prepare file-editing context, search symbols, summarize modules, review pull requests, and investigate bugs.

It reduces the need to search files manually when you need to understand how code is connected or what a change might affect.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/codegraph-ai/codegraph-rules-for-agents

Made for: Cursor.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00617	$0.00617
Opus 5.5	$0.00247	$0.00247
Sonnet 5.5	$0.00123	$0.00123
Haiku 4.5	$0.00062	$0.00062

Security

Grade A, and why

codegraph 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 1mo 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.

CodeGraph — local code intelligence

Persistent semantic graph of your codebase. Resolves references — "who calls X?" is a single tool call, not multi-file grep.

First time? Run codegraph_reindex_workspace once (5-30s). Index persists across sessions.

Top 5 tools (use these first)

When you need	Call this	NOT this
Who calls function X?	`codegraph_get_callers`	grep for the function name
What breaks if I change X?	`codegraph_analyze_impact`	reading every importing file
Context for editing a file	`codegraph_get_edit_context`	reading 5+ files manually
Find a symbol by name	`codegraph_symbol_search`	grep -r across the project
Module structure overview	`codegraph_get_module_summary`	ls + reading each file

URI format: file:///absolute/path. Use paths from symbol_search results directly. Compact mode: pass compact: true for shorter output when scanning.

Common workflows

PR review: pr_context — one call: blast radius, test gaps, stale docs, reviewers
Refactoring: symbol_search → analyze_impact → get_edit_context
Bug triage: search_by_error → get_callers → get_ai_context(intent: "debug")
Onboarding: get_module_summary → find_entry_points → get_call_graph

Decision rule

Structural question? (callers, deps, impact) → codegraph tools
Text question? (exact string, regex) → grep/read
Not sure? → Try codegraph_symbol_search first. Empty → run codegraph_reindex_workspace.

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.

codegraph is a cursor rule published in the GitHub repository codegraph-ai/codegraph-rules-for-agents (3 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 617 tokens to every session, about $0.0025 per session on Opus 5.5. 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 2026-08-31.
