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 | $0.00033 | $0.00592 |
| Opus 5 | $0.00016 | $0.00296 |
| Sonnet 5 | $0.00007 | $0.00118 |
| Haiku 4.5 | $0.00003 | $0.00059 |
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.
This is a copy
94% identical to Repository Investigation Reviewer — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.
Review checks
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.

Repository Investigation Reviewer is an agent published in the GitHub repository Cratis/VerticalSlices (2 stars, last pushed 7d ago), licensed MIT. It adds 33 tokens to every session and 592 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to Repository Investigation Reviewer, differing in 2 lines, and is treated as a copy.
Other agents, from other repositories
Code Reviewer
Quality gate agent for Cratis-based projects. Reviews code against all project instruction files, checking architecture conformance, C# and TypeScript conventions, and vertical slice correctness before merge.
Performance Reviewer
Performance-focused review agent for Cratis-based projects. Analyzes changed files for projection efficiency, query patterns, unnecessary allocations, React render overhead, and Chronicle anti-patterns before merge.
Security Reviewer
Security gate agent for Cratis-based projects. Performs a structured security review of all changed files before merge, covering input validation, auth/authz, data exposure, secrets, event sourcing specifics, and frontend attack surface.
Repository Investigation Reviewer
Independent, read-only reviewer for typed Cratis repository investigations. Reviews evidence and repository-mode reasoning without applying application conventions to framework or client-library repositories.
Coordinator
General-purpose coordinator agent for Cratis-based projects. Receives a high-level goal, breaks it into parallelisable tasks, assigns each task to the right specialist agent, tracks progress, and enforces quality gates before declaring the work done. Use this agent when a request spans multiple concerns (backend +…
Frontend Developer
Specialist for TypeScript/React frontend code within a vertical slice. Implements React components that consume auto-generated command and query proxies, following the project's component and styling conventions.
