What is codegraph CLAUDE.md?

Project instructions for codegraph, a Go tool that indexes a code repository into a SQLite knowledge graph of symbols and relationships. AI agents can query who calls what and search the code without reading every file.

Maintaining the repository index, querying callers and callees, searching symbols, working with the SQLite graph and full-text search, and preserving the project’s Go and token-use design rules.

The graph gives agents compact references to relevant code, reducing the need to load whole files into their context. The instructions also protect design choices such as returning references first and retrieving code snippets separately.

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	$0.02284	$0.02284
Opus 5.5	$0.00914	$0.00914
Sonnet 5.5	$0.00457	$0.00457

Security

Grade A, and why

codegraph CLAUDE.md 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 2mo 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.

CLAUDE.md — codegraph

Trabalhe SEMPRE a partir desta pasta (d:/projetos/codegraph), abrindo a sessão do Claude Code aqui dentro — não pela pasta do ajudaqui. Este projeto é independente, com git próprio.

O que é

codegraph — grafo de conhecimento de código token-efficient para agentes de IA, em Go. Reimplementação enxuta das ideias do DeusData/codebase-memory-mcp (que é C puro). Foco no stack do Rafael (TypeScript/JS + Go + NestJS), não 158 linguagens. Module: github.com/Lordymine/codegraph. Go 1.26.

Indexa um repo → grafo SQLite de símbolos + relações; o agente consulta o grafo (quem-chama, callers/callees, busca rankeada) em vez de ler arquivo por arquivo.

Princípios de design (não violar sem motivo)

Storage é trivial — 2 tabelas (nodes, edges) + FTS5, igual ao upstream. O valor está nas arestas CALLS, não no banco.
Token-efficient por construção — toda query retorna ref compacta (name + qualified_name + label + file + line), NUNCA código. Código só via a tool snippet. É daí que vem o ~10× de economia de token.
Aposta-chave: delegar ao type-checker da linguagem, não reimplementar. O upstream refez resolução de tipos em C ("Hybrid LSP", ~9 langs, meses de trabalho). Nós delegamos a resolução de chamadas aos indexadores batch da linguagem — scip-typescript (TS/JS) e go/packages + go/callgraph (Go, as libs que o próprio gopls usa) — lidos in-process. Mesma precisão de type-checker real, num passe só, sem servidor LSP vivo pra babá. Pulamos a parte mais difícil do port.
Precisão honesta — aresta não resolvida é descartada (endpoints precisam existir no grafo). Melhor aresta faltando que aresta errada.
Poucas dependências — SQLite puro-Go (modernc.org/sqlite), MCP server em stdlib. tree-sitter (cgo) é a dep pesada do M1 — por isso o build exige CGO_ENABLED=1 + gcc. scip-typescript entra como ferramenta de build (Node), não liga no binário.
