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 | $0.00743 | $0.00743 |
| Opus 5.5 | $0.00297 | $0.00297 |
| Sonnet 5.5 | $0.00149 | $0.00149 |
| Haiku 4.5 | $0.00074 | $0.00074 |
Grade A, and why
factory-factory AGENTS.md 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 9d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Factory Factory — Agent Guide
TypeScript workspace manager for Claude Code/Codex: Express + tRPC, React +
Vite, Prisma/SQLite, Electron, and the ff CLI.
Use Node pinned in .node-version and pnpm pinned in package.json; never npm
or yarn. Electron uses its bundled runtime.
Working approach
Complete the requested work, checks, and delivery. Make routine reversible decisions; ask when missing input changes scope, correctness, or authorization. Keep changes focused. User instructions override skill guidelines; reuse authorization and apply only relevant skills. Identify the exact blocking rule if clarification is needed.
Verification and delivery
Follow verification and pull request conventions. Update docs when behavior changes; report checks run and any failures or limitations.
Architecture and style
Read the applicable backend service or client feature guide before editing those areas.
- Service capsules own logic and Prisma resources; cross-service coordination
belongs in
src/backend/orchestration/. Use service/feature barrels across boundaries, with the exceptions in the area guides. - Features own UI and hooks; routes compose them.
src/components/is reserved for shadcn/ui; app code belongs insrc/client/. - Client code may import backend only for tRPC types.
src/shared/imports neither backend nor client. No circular imports orawait import(). - Aliases:
@/*→src/;@prisma-gen/*→prisma/generated/. - Read environment through
configService(@/backend/services/config.service), neverprocess.env. - Validate boundaries and
JSON.parseresults with Zod; do not cast parsed data. Use specific schemas or narrowedz.unknown(), neverz.any(). - Use
ConfirmDialog/AlertDialog, never nativealert/confirm/prompt. No'use client'/'use server'directives; this is not Next.js. - Read lint guardrails before changing lint policy.
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.

factory-factory AGENTS.md is an instructions file published in the GitHub repository purplefish-ai/factory-factory (52 stars, last pushed today), licensed MIT. It adds 743 tokens to every session, about $0.0030 per session on Opus 5.5. 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 2026-08-30.
