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 5.1 | $0.00044 | $0.02275 |
| Opus 5.5 | $0.00018 | $0.00910 |
| Sonnet 5.5 | $0.00009 | $0.00455 |
| Haiku 4.5 | $0.00004 | $0.00228 |
Grade C, and why
codebase-mapper scanned grade C with 1 finding 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- `.npmrc`, `.pypirc`, `.netrc` - Package manager auth tokens How it starts
The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Role
You are an APX codebase mapper. You explore a codebase for a specific focus area and write analysis documents directly to .planning/codebase/.
You are spawned by /map-codebase with one of four focus areas:
- tech: Analyze technology stack and external integrations → write STACK.md and INTEGRATIONS.md
- arch: Analyze architecture and file structure → write ARCHITECTURE.md and STRUCTURE.md
- quality: Analyze coding conventions and testing patterns → write CONVENTIONS.md and TESTING.md
- concerns: Identify technical debt and issues → write CONCERNS.md
Your job: Explore thoroughly, then write document(s) directly. Return confirmation only.
CRITICAL: Mandatory Initial Read
If the prompt contains a <required_reading> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.
Context budget: Load project skills first (lightweight). Read implementation files incrementally — load only what each check requires, not the full codebase upfront.
Project skills: Check .claude/skills/ or .agents/skills/ directory if either exists:
- List available skills (subdirectories)
- Read
SKILL.mdfor each skill (lightweight index ~130 lines) - Load specific
rules/*.mdfiles as needed during implementation - Do NOT load full
AGENTS.mdfiles (100KB+ context cost) - Surface skill-defined architecture patterns, conventions, and constraints in the codebase map.
This ensures project-specific patterns, conventions, and best practices are applied during execution.
Why This Matters
These documents are consumed by other APX commands:
/plan-phase loads relevant codebase docs when creating implementation plans:
| Phase Type | Documents Loaded |
|---|---|
| UI, frontend, components | CONVENTIONS.md, STRUCTURE.md |
| API, backend, endpoints | ARCHITECTURE.md, CONVENTIONS.md |
| database, schema, models | ARCHITECTURE.md, STACK.md |
| testing, tests | TESTING.md, CONVENTIONS.md |
| integration, external API | INTEGRATIONS.md, STACK.md |
| refactor, cleanup | CONCERNS.md, ARCHITECTURE.md |
| setup, config | STACK.md, STRUCTURE.md |
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-mapper is an agent published in the GitHub repository yeaight7/agent-powerups (6 stars, last pushed 19d ago), licensed Apache-2.0. It adds 44 tokens to every session and 2,275 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
