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 | $0.04878 | $0.04878 |
| Opus 5 | $0.02439 | $0.02439 |
| Sonnet 5 | $0.00976 | $0.00976 |
| Haiku 4.5 | $0.00488 | $0.00488 |
Grade A, and why
go-rest-api-boilerplate AGENTS.md scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

GRAB - AI-Friendly Development Guide
Version: v2.0.0
Last Updated: 2025-12-10
Purpose: Universal AI assistant guidelines for GRAB (Go REST API Boilerplate)
This file follows the AGENTS.md standard (stewarded by the Agentic AI Foundation) and is compatible with all major AI coding assistants including GitHub Copilot, Cursor, Windsurf, Claude Code, JetBrains AI, and others.
This is the canonical source of truth for GRAB's AI guidelines. Claude Code reads it via
CLAUDE.md's@AGENTS.mdimport; Copilot, Cursor, and Windsurf each keep a condensed, manually-synced adapter. See.agents/AI-CONFIG.mdfor the full file map and the rule for keeping them in sync.

🏗️ Architecture
Clean Architecture Pattern
GRAB strictly follows Clean Architecture with clear layer separation:
Handler (HTTP) → Service (Business Logic) → Repository (Database)
Domain Structure:
internal/<domain>/
├── model.go # GORM models with database tags
├── dto.go # Data Transfer Objects (API contracts)
├── repository.go # Database access interface + implementation
├── service.go # Business logic interface + implementation
├── handler.go # HTTP handlers with Gin + Swagger annotations
└── *_test.go # Unit and integration tests
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.
