codebase-profiler

A bounded codebase review that describes a project's architecture, modules, coding conventions, and recurring pitfalls. It writes a structured profile rather than permanent knowledge entries and avoids secret material.

In plain words
What is it for?
Use it to map dependency direction, note naming and testing practices, identify sharp edges, and record which areas were not reviewed.
Why use it?
It gives later documentation work an overview of how the project is organised without searching the entire codebase indefinitely.

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-profiler 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.

What it actually says

codebase-profiler

Profile the project within ~60 searches (stop when the budget is spent). Write docs/knowledge-import/02-profile.md:

  • Architecture layers + dependency direction.
  • Conventions actually followed (naming, error handling, testing).
  • Recurring pitfalls / sharp edges.

Secret boundary

Never read or record known secret files such as .env, .env.*, private keys (*.pem, *.key, *.p12, *.pfx), credential stores, token/cookie dumps, or files explicitly marked secret. If a normal source file unexpectedly contains credential-like material, never print or copy the secret value: note only the affected path with a redacted warning and exclude that material from the profile.

Stay within the search budget; note what you did NOT cover. Return a one-line summary.

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.

codebase-profiler is an agent published in the GitHub repository shenchangmin/cairnkit (1 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 238 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.
