.claude/agents/crd-investigator.md

crd-investigator is an agent for Claude Code from vinzenz/prd-breakdown-execute. It costs 30 tokens per session (1,412 once invoked), scanned A, original, no licence file.

An agent that studies a codebase and records its architecture, patterns, features, application interfaces, and data schemas in PROJECT.md. The file gives coding agents context about the project.

In plain words
What is it for?
Investigating an unfamiliar repository and creating project context covering its structure, behavior, APIs, and schemas.
Why use it?
It reduces the need to rediscover how a project works before making changes.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is vinzenz/prd-breakdown-execute's own configuration. It tells Claude Code how to work on prd-breakdown-execute itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything prd-breakdown-execute configures →

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

crd-investigator 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 7d 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.

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.
