ccc-update-codemaps

ccc-update-codemaps is a command for coding agents from KevinZai/commander. It costs 12 tokens per session (583 once invoked), scanned A, a copy of update-codemaps, MIT.

A codebase mapping tool that turns a project's structure into compact architecture documents. It can describe services, APIs, frontend components, databases, dependencies, and data flow, including projects with multiple packages called a monorepo.

In plain words
What is it for?
Use it to document entry points, API routes, service layers, component trees, database relationships, migrations, and external integrations.
Why use it?
It makes a large or unfamiliar codebase easier to understand and gives coding agents concise architecture context. Updating the maps reduces the need to rediscover the project structure.

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

ccc-update-codemaps 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 today.

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.

Update Codemaps

Analyze the codebase structure and generate token-lean architecture documentation.

Step 1: Scan Project Structure

  1. Identify the project type (monorepo, single app, library, microservice)
  2. Find all source directories (src/, lib/, app/, packages/)
  3. Map entry points (main.ts, index.ts, app.py, main.go, etc.)

Step 2: Generate Codemaps

Create or update codemaps in docs/CODEMAPS/ (or .reports/codemaps/):

File Contents
architecture.md High-level system diagram, service boundaries, data flow
backend.md API routes, middleware chain, service → repository mapping
frontend.md Page tree, component hierarchy, state management flow
data.md Database tables, relationships, migration history
dependencies.md External services, third-party integrations, shared libraries

Codemap Format

Each codemap should be token-lean — optimized for AI context consumption:

# Backend Architecture

## Routes
POST /api/users → UserController.create → UserService.create → UserRepo.insert
GET  /api/users/:id → UserController.get → UserService.findById → UserRepo.findById

## Key Files
src/services/user.ts (business logic, 120 lines)
src/repos/user.ts (database access, 80 lines)

## Dependencies
- PostgreSQL (primary data store)
- Redis (session cache, rate limiting)
- Stripe (payment processing)

Step 3: Diff Detection

  1. If previous codemaps exist, calculate the diff percentage
  2. If changes > 30%, show the diff and request user approval before overwriting
  3. If changes <= 30%, update in place

Step 4: Add Metadata

Add a freshness header to each codemap:

<!-- Generated: 2026-02-11 | Files scanned: 142 | Token estimate: ~800 -->

Step 5: Save Analysis Report

Write a summary to .reports/codemap-diff.txt:

  • Files added/removed/modified since last scan
  • New dependencies detected
  • Architecture changes (new routes, new services, etc.)
  • Staleness warnings for docs not updated in 90+ days

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.
