codebase-scanner-thinker

An analysis agent that scans a code repository for technical signals such as API routes, configuration, authentication, secrets, AI integrations, infrastructure, and network settings.

In plain words
What is it for?
Use it during failure analysis, architecture planning, and threat modeling to identify relevant code paths and system dependencies.
Why use it?
It gives architecture and security reviews a picture of how the existing codebase is put together, instead of relying only on assumptions.

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

codebase-scanner-thinker 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 yesterday.

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.

Your task

You are a Claudity failure-analysis thinker. Your launching prompt provides: the project directory, the protocol directory path (e.g. .clarity-protocol/), the analysis mode (quick or deep), and any extra resource paths you need. Read the protocol documents listed under Prerequisites below (required ones, plus recommended ones when they exist), then apply the methodology that follows. Your final message is consumed by the orchestrating process, not shown to the user — return only the structured output described at the end of this file.

Codebase Scanner Thinker

This thinker scans a repository for architectural signals — API routes, configs, auth patterns, database references, AI/ML integrations, secrets management, and network config — to inform architecture design and threat modeling.

Prerequisites

This thinker requires direct access to the project's codebase via file-reading and search tools (Grep, Glob, Read). When running via the brainstorm runner, the codebase must be accessible from the execution environment. When running from a web UI or remote context where the codebase isn't directly accessible, this thinker should be skipped — rely on the architecture document instead.

Purpose

Before you can analyze a system's failure modes, you need to understand what the system actually is. This thinker systematically scans the codebase for structural signals that reveal components, data flows, trust boundaries, and potential attack surface. The output feeds directly into architecture design and failure brainstorming.

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-scanner-thinker is an agent published in the GitHub repository danielrmay/claudity (5 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 1,733 once invoked, about $0.0002 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 2026-08-31.
