codemap

codemap is a skill for Claude Code from jellydn/my-ai-tools. It costs 22 tokens per session (2,150 once invoked), scanned A, original, MIT.

A skill that studies a codebase and creates seven planning documents covering its technologies, integrations, architecture, layout, conventions, testing, and concerns.

In plain words
What is it for?
Use it for onboarding, feature planning, architecture discovery, convention checks, and identifying technical debt, bugs, security risks, or performance issues.
Why use it?
It gives developers a structured overview of an unfamiliar repository before they plan changes or investigate problems.

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

codemap 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 8d 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.

Codemap

What I do

Analyze your entire codebase and create 7 comprehensive documentation files in .planning/codebase/:

  • STACK.md - Technologies, dependencies, configuration
  • INTEGRATIONS.md - 3rd party providers, APIs, databases, auth providers
  • ARCHITECTURE.md - System patterns, layers, data flow
  • STRUCTURE.md - Directory layout, key locations, naming conventions
  • CONVENTIONS.md - Code style, patterns, error handling
  • TESTING.md - Framework, structure, mocking, coverage
  • CONCERNS.md - Tech debt, bugs, security, performance issues

When to use me

Use this skill when you need to:

  • Onboard new developers to understand the codebase quickly
  • Plan new features with full context of existing patterns
  • Understand code conventions before making changes
  • Identify technical debt and areas of concern
  • Document the current state of the project

How it works

This skill orchestrates 4 parallel agents, each exploring a specific focus area:

  1. Tech Agent → Analyzes stack and integrations → STACK.md, INTEGRATIONS.md
  2. Architecture Agent → Analyzes patterns and structure → ARCHITECTURE.md, STRUCTURE.md
  3. Quality Agent → Analyzes conventions and testing → CONVENTIONS.md, TESTING.md
  4. Concerns Agent → Identifies tech debt and issues → CONCERNS.md

Each agent:

  • Explores the codebase in a fresh context
  • Uses templates from $SKILL_PATH/templates/
  • Writes documents directly to .planning/codebase/
  • Returns only confirmation (not document contents)

The orchestrator:

  • Creates .planning/codebase/ directory
  • Spawns 4 parallel agents with run_in_background=true
  • Collects confirmations
  • Verifies all documents created
  • Commits the codebase map (if configured)

Process

Step 1: Check Existing Map

If .planning/codebase/ already exists, prompt:

.planning/codebase/ already exists. What's next?
1. Refresh - Delete existing and remap codebase
2. Update - Keep existing, only update specific documents
3. Skip - Use existing codebase map as-is

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

codemap is a skill published in the GitHub repository jellydn/my-ai-tools (119 stars, last pushed 3d ago), licensed MIT. It adds 22 tokens to every session and 2,150 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.
