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.

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 | $0.02108 | $0.02108 |
| Opus 5 | $0.01054 | $0.01054 |
| Sonnet 5 | $0.00422 | $0.00422 |
| Haiku 4.5 | $0.00211 | $0.00211 |
Grade A, and why
codebase-intelligence 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 yesterday.
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.

Codebase Intelligence - Claude Code Rules
Project Overview
npm package that analyzes TypeScript codebases — parses source, builds dependency graphs, computes architectural metrics, and exposes everything via MCP stdio for LLM-assisted code understanding.
Architecture
src/
types/index.ts <- All TypeScript interfaces (single source of truth)
parser/index.ts <- TS Compiler API parser (files, functions, imports)
graph/index.ts <- graphology graph builder + circular dep detection
analyzer/index.ts <- Metrics engine (PageRank, betweenness, cohesion, tension, churn, complexity, blast radius, dead exports)
mcp/index.ts <- MCP stdio server (16 tools, 2 prompts, 3 resources)
mcp/hints.ts <- Next-step hints for MCP tool responses
server/graph-store.ts <- Global graph state (shared by CLI + MCP)
impact/index.ts <- Symbol-level impact analysis + rename planning
search/index.ts <- BM25 search engine
process/index.ts <- Entry point detection + call chain tracing
community/index.ts <- Louvain clustering
persistence/index.ts <- Graph export/import to .code-visualizer/
install/index.ts <- Agent adoption: managed-block engine + per-agent files + skill (init)
config/index.ts <- Config discovery + zod validation (codebase-intelligence.json)
rules/index.ts <- Rules engine + registry (check command + MCP check tool)
cli.ts <- CLI entry point (commander)
docs/
architecture.md <- Pipeline, module map, data flow, design decisions
data-model.md <- All TypeScript interfaces with field descriptions
metrics.md <- Per-file + module metrics, force analysis, complexity scoring
mcp-tools.md <- 16 MCP tools: inputs, outputs, use cases, selection guide
specs/
active/ <- Current spec
Pipeline
CLI args -> Parser (TS AST) -> Graph Builder (graphology) -> Analyzer (metrics) -> MCP stdio
Key Conventions
TypeScript
- ESM modules (
"type": "module") - Bundler module resolution
- Strict mode enabled
- All internal imports use
.jsextension (ESM convention) - Types defined in
src/types/index.ts— import from there, never duplicate import typefor type-only imports (enforced by ESLint)
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.

codebase-intelligence CLAUDE.md is an instructions file published in the GitHub repository bntvllnt/codebase-intelligence (7 stars, last pushed 2mo ago), licensed MIT. It adds 2,108 tokens to every session, about $0.0105 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 2026-08-31.
