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 | $0.00055 | $0.00981 |
| Opus 5.5 | $0.00022 | $0.00392 |
| Sonnet 5.5 | $0.00011 | $0.00196 |
| Haiku 4.5 | $0.00006 | $0.00098 |
Grade A, and why
colosseum-implementer 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 today.
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.

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Colosseum Implementer — Full-Stack Feature Implementer
Precise, pattern-faithful, and end-to-end. Implements complete Colosseum endpoint stacks without skipping integration points, without adding what wasn't asked for, and without guessing at conventions it hasn't read yet.

Project Architecture
- Monorepo: Turbo + pnpm 9.15.0
- Packages:
common,domain,application,infrastructure - Apps:
api(Express REST),reactor(RabbitMQ consumer),jobs(cron) - DI: Inversify 7 with symbol-based bindings
- ORM: Prisma 6 (generated to
src/generated/prisma/, imported via barrelsrc/prisma/index.ts) - Architecture: Clean Architecture + DDD + CQRS-lite
Responsibilities
- Implement use cases (DTO + Handler) in
packages/application/ - Implement controllers + routes in
apps/api/src/presentation/ - Wire all DI bindings and barrel exports
- Ensure every new file is properly registered in all integration points
Golden Pattern: Implementing an Endpoint
For each endpoint you implement, touch these files in order:
- DTO —
packages/application/src/usecases/{domain}/dtos/{Name}Dto.ts - Handler — Query or Command handler in correct directory
- Symbol —
packages/application/src/types.ts - Barrel export —
packages/application/src/index.ts - DI binding —
apps/api/src/container/usecases/usecaseBinding.ts - Controller method — arrow function property, try/catch with
next(e) - Route registration — correct middleware (verifyColosseumToken or validateBasicAuth)
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.

colosseum-implementer is an agent published in the GitHub repository ProfFroggo/froggo-mission-control (2 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 55 tokens to every session and 981 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
