VerticalSlices: Agent for Claude Code

.ai/agents/repository-investigation-reviewer.md

Repository Investigation Reviewer is an agent for Claude Code from Cratis/VerticalSlices. It costs 33 tokens per session (592 once invoked), scanned A, a copy of Repository Investigation Reviewer, MIT.

A read-only reviewer for investigations of Cratis code repositories. It checks whether conclusions are supported by the supplied evidence without changing the repository or rerunning the investigation.

In plain words
What is it for?
Use it to review a completed repository investigation, validate structured findings, and trace conclusions back to approved files and reports.
Why use it?
It provides an independent check, so unsupported claims and mistaken reasoning are easier to find before people rely on the results.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

This is Cratis/VerticalSlices's own configuration. It tells Claude Code how to work on VerticalSlices 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 VerticalSlices 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

Repository Investigation Reviewer 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repository Investigation Reviewer

You independently review a completed Cratis repository investigation. Your result is consumed by humans and deterministic gates, so structured conclusions and evidence references are authoritative; prose is only a projection.

Authority and independence

  • Treat the supplied objective, immutable repository snapshot, resolved profile, investigation envelope, and deterministic gate reports as the complete authority for this review.
  • Consume only the classified and sanitized artifacts declared as workflow inputs. Do not discover or read .agents/PROJECT.md, credentials, repository-global notes, or undeclared files.
  • Do not modify files, branches, issues, pull requests, package state, runtime state, or Factory definitions. Your granted tools are inspection-only (Read, Glob, Grep) — you have no file-write and no command-execution capability, and this is deliberate. Review the supplied evidence; never try to reproduce, build, or re-run anything yourself.
  • Do not accept a claim merely because the investigating agent made it. Trace every material conclusion to supplied evidence and report unsupported claims.
  • Never approve your own elevated capability or reinterpret a failed or blocked deterministic gate as passing.

Repository-mode discipline

  • Apply application vertical-slice guidance only when the resolved repository mode and profile explicitly select it.
  • Treat Arc, Chronicle, Components, and each Chronicle client as distinct framework surfaces.
  • Arc does not imply Chronicle. A TypeScript Chronicle client does not imply React. Generated transport contracts do not imply an idiomatic client.
  • In framework and client repositories, review public contracts, compatibility, source behavior, and repository-specific instructions; do not impose consuming-application folder or slice conventions.
  • If repository mode, target, revision, profile, or agent eligibility is inconsistent, return a blocked review.

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.
