Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00783 | $0.00783 |
| Opus 5 | $0.00392 | $0.00392 |
| Sonnet 5 | $0.00157 | $0.00157 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
GoModel 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 2d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This project is GoModel - a high-performance, lightweight AI gateway that routes requests to multiple AI model providers through an OpenAI-compatible API.
Core Principles
Follow Postel’s Law
Accept user requests generously, adapt them to each provider’s requirements, and return conservative OpenAI-compatible responses.
Examples:
- Accept
max_tokensfrom users even when a provider expects another field. - Translate
max_tokenstomax_completion_tokensfor OpenAI reasoning models when required. - Normalize provider responses into an OpenAI-compatible shape.
Follow The Twelve-Factor App
Prefer production-friendly service design:
- Configuration through environment variables.
- Stateless request handling.
- Clear separation between configuration, routing, provider adapters, and runtime behavior.
- Useful logs for containers and cloud environments.

Keep It Simple
Keep files small.
Prefer explicit, maintainable code over clever abstractions.
Do not add abstractions until a repeated pattern clearly justifies them.
Use Good Defaults
Defaults should fit most users so well that they rarely need to change them.
When adding configuration:
- Choose a safe, practical default.
- Avoid requiring configuration for common use cases.
- Document when and why users should override the default.
Implementation Guidance
When changing provider behavior:
- Preserve the OpenAI-compatible public API.
- Keep provider-specific logic isolated.
- Avoid leaking provider-specific quirks into user-facing behavior.
- Never expose API keys, authorization headers, or secrets in errors or logs.
When editing code:
- Make the smallest change that solves the problem.
- Use idiomatic Go.
- Prefer clear names, small interfaces, simple structs, and table-driven tests.
- Avoid hidden global state, unnecessary reflection, and premature optimization.
- Add or update tests for behavior changes.
Tests should cover request translation, response normalization, error handling, default configuration, and provider-specific parameter mapping.
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.

GoModel CLAUDE.md is an instructions file published in the GitHub repository ENTERPILOT/GoModel (1,097 stars, last pushed 2d ago), licensed MIT. It adds 783 tokens to every session, about $0.0039 per session on Opus 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.
