What is codebase-analyzer CLAUDE.md?

A project instruction file for a codebase-analysis plugin. It defines how the plugin maps software structure, studies its history and behavior, and records its conclusions.

Use it when maintaining or extending the codebase-analyzer plugin, especially its analysis skills, agents, output files, and development workflow.

It gives coding agents consistent rules for investigating unfamiliar code and reporting evidence. This reduces guesswork and keeps analysis results in a standard format.

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	$0.00515	$0.00515
Opus 5.5	$0.00206	$0.00206
Sonnet 5.5	$0.00103	$0.00103
Haiku 4.5	$0.00052	$0.00052

Security

Grade A, and why

codebase-analyzer 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.

codebase-analyzer Plugin

Architecture

32 skills + 3 agents
Track A (reconnaissance) -> Track B (deep dive) -> System Intent
Orchestration skills cloned from superpowers (vendor/superpowers/) for development workflows
Standard output contract in docs/analysis/

Three Depths Model

Surface (Track A): Fast structural scans, architecture maps
Deep (Track B Phases 1-3): Git archaeology, gate extraction, behavior simulation
Intent (Track B Phase 4): Reconstruct what the system was built to do

Skill Standards

Description field: starts with "Use when...", triggers only, no workflow summary
Every skill writes to docs/analysis/ using standard contract
Trigger signals include: priority (high/med/low), confidence (high/med/low), evidence (file:line)

Behavioral Engineering

Skills are behavioral software, not reference documentation
Every skill includes: announce line, red flags, output contract
Critical skills include: Iron Law, rationalization table, HARD-GATE
Description field: trigger-only (CSO rule), never summarize workflow

File Naming

Skills: skills/<verb>-<noun>/SKILL.md
References: skills/<verb>-<noun>/references/<topic>.md
Agents: agents/<noun>.md

Testing

RED-GREEN-REFACTOR for each skill
Test against diverse repo types (web app, library, IaC, monorepo)

Multi-Platform Support

Claude Code: Primary target. SessionStart hook, plugin manifests, Skill tool, full agent dispatch.
OpenCode: ESM plugin at .opencode/plugins/codebase-analyzer.js. Config hook + message transform. No agent dispatch (degraded mode).
Codex: Symlink-based skill discovery (~/.agents/skills/). AGENTS.md symlink. Sandbox fallback mode. No agent dispatch (degraded mode).
Platform capabilities: Defined in skills/using-codebase-analyzer/PLATFORM-NOTES.md (single source of truth).
Validation: scripts/validate.sh checks all skills, agents, hooks, and plugin health.
Upstream sync: scripts/sync-upstream.sh pulls upstream superpowers via git subtree + rebuilds skills.

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.
