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 | $0.00560 | $0.00560 |
| Opus 5.5 | $0.00224 | $0.00224 |
| Sonnet 5.5 | $0.00112 | $0.00112 |
| Haiku 4.5 | $0.00056 | $0.00056 |
Grade A, and why
agent-system 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 1mo 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Baseline Project Guidelines
MCP Tools
Context7 - MUST USE
When to use:
- Always when looking up library documentation
- When troubleshooting library-specific issues
- Before implementing features with external dependencies
How to use:
mcp__context7__resolve-library-id- Find the library IDmcp__context7__get-library-docs- Get documentation with the ID from step 1
Why: Ensures current, accurate documentation rather than outdated knowledge.
Code Quality
Comments
Only write comments for:
- Complex algorithms that aren't immediately obvious
- Non-obvious workarounds for known issues/bugs
- Critical "why" explanations that code cannot express
99% of code should be self-explanatory through:
- Clear, descriptive naming
- Proper structure and organization
- Following language best practices
Git Workflow
Commit Messages
Use Conventional Commits format:
feat:- New featuresfix:- Bug fixesrefactor:- Code refactoringdocs:- Documentation changestest:- Test updateschore:- Maintenance tasks
Example: feat: add user authentication system
Branch Naming
Use type prefixes:
feature/- New featuresfix/- Bug fixesrefactor/- Code refactoring
Example: feature/user-authentication
Engineering Philosophy
Approach
- Pragmatic over perfect - Ship working solutions, iterate if needed
- Question assumptions - Always ask clarifying questions before building
- YAGNI - Don't over-engineer; build what's needed now
- KISS - Prefer simple solutions over complex ones
Communication Style
- Ask questions when requirements are unclear or ambiguous
- Brainstorm ideas - discuss different approaches
- Find optimal approach - balance simplicity, maintainability, and effectiveness
- Avoid over-engineering - question if complexity is truly necessary
- Be concise - get to the point, focus on solutions
Venue Context
Use the venue-expert skill for exchange-specific context. Invoke it when:
- Starting any research involving exchange data
- Debugging trading system issues (feed, order, session problems)
- Needing venue mechanics: order types, matching rules, session times, data formats, regulatory quirks
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.

agent-system CLAUDE.md is an instructions file published in the GitHub repository DeevsDeevs/agent-system (41 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 560 tokens to every session, about $0.0022 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.
