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 | $0.01522 | $0.01522 |
| Opus 5.5 | $0.00609 | $0.00609 |
| Sonnet 5.5 | $0.00304 | $0.00304 |
| Haiku 4.5 | $0.00152 | $0.00152 |
Grade A, and why
codework CLAUDE.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.
This is a copy
95% identical to codework AGENTS.md — 12 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Personal Preference
TypeScript
- Never use
anyunless 100% necessary or specifically instructed. - Use effect only if the project uses effect or specifically instructed, use effect reference repository for latest architecture patterns.
Commands
- Don't run dev server commands (e.g
pnpm run dev,bun run dev) - assume it's already running. - Don't run build commands unless specifically told to.
- Focus on checking commands like
pnpm run check,bun run lintbun run typecheck, etc.
Package Managers
- Use
pnpm,vp - vite plusif the project already uses it, otherwise usepnpm - Never use
npmoryarn
Tech Stack Preference
When uncertain, prefer: Effect, Tailwind, TypeScript, React, Clerk, TanStack, Vercel, Vite.
Code Style
- Always strive for concise, simple solutions.
- If a problem can be solved in a simpler way, propose it.
- No pre-mature optimizations, propose if required.
- Use single word filename whenever possible otherwise split into kabab-case(only if no options).
General Preferences
- If asked to do too much work at once, stop and state that clearly.
- After you yourself have verified the work, get the work peer reviewed by another agent:
codexforcode reviews,focused deep checks,tweaks,tests reviewshell out togpt-6.1-solwith thinkinglowormediumdepending on complexity. - Avoid defensive future-facing design. This leads to pre-mature assumptions which are never true.
Maintainability
Long term maintainability is a core priority. If you add new functionality, first check if there is shared logic that can be extracted to a separate module. Duplicate logic across multiple files is a code smell and should be avoided. Don't be afraid to change existing code. Don't take shortcuts by just adding local logic to solve a problem.
Package Roles
packages/aikit- Low level SDK that provides unified LLM API for multiple LLM providers.packages/harness- Effect powered main Agent Harness application, usespackages/aikitunder the hood.packages/plugin- The published SDK third-party plugin and sandbox-driver packages build against. It owns the shared contract (plugin, tool, sandbox mount, event and settings types);packages/harnessdepends on it, never the other way round..scratch/packages- Local, ignored reference archive for packages that are no longer developed.
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.

codework CLAUDE.md is an instructions file published in the GitHub repository codeworksh/codework (24 stars, last pushed yesterday), licensed MIT. It adds 1,522 tokens to every session, about $0.0061 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 95% identical to codework AGENTS.md, differing in 12 lines, and is treated as a copy.
