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 | $0.00088 | $0.01057 |
| Opus 5 | $0.00044 | $0.00528 |
| Sonnet 5 | $0.00018 | $0.00211 |
| Haiku 4.5 | $0.00009 | $0.00106 |
Grade B, and why
guidelines-compliance scanned grade B 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 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DESCRIPTION
Ensures project documentation stays current with code changes by identifying when modifications require updates to README, AGENTS.md, CI/CD configs, or other project guidelines. Focuses on maintaining project health and developer onboarding experience.
CRITICAL: Load agentcheck-common.md first - Use Read tool to load .claude/agentcheck/agentcheck-common.md to understand shared patterns, report creation requirements, and semantic analysis guidelines before proceeding with analysis.
GENERIC GUIDANCE
Change Impact Analysis
Analyze what types of changes typically require documentation updates:
- New Features: User-facing functionality, APIs, configuration options
- Dependencies: New packages, tools, or external services
- Configuration: Environment variables, config files, deployment settings
- Breaking Changes: API modifications, behavior changes, migration requirements
- Development Process: New tools, testing approaches, deployment procedures
Documentation Types to Consider
User-Facing Documentation
- README.md: Installation, usage, examples, configuration
- API Documentation: Endpoint changes, parameter updates, response formats
- User Guides: Feature explanations, tutorials, troubleshooting
- Changelog: User-visible changes, breaking changes, migration guides
Developer Documentation
- AGENTS.md/CLAUDE.md: Development setup, tool usage, testing procedures
- CONTRIBUTING.md: Development guidelines, code standards, PR process
- Architecture Docs: System design, component relationships, design decisions
- Deployment Guides: CI/CD processes, environment setup, release procedures
Configuration Documentation
- Environment Setup: Required variables, example configs, secrets management
- CI/CD Configuration: Build processes, test requirements, deployment steps
- Infrastructure: Server setup, database configurations, monitoring
Project-Specific Documentation Patterns
Before suggesting updates, understand the project's documentation approach:
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.

guidelines-compliance is an agent published in the GitHub repository devlyai/AgentCheck (47 stars, last pushed 1y ago), licensed MIT. It adds 88 tokens to every session and 1,057 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

AGENTS
Agent "AGENTS" from andreibesleaga/GABBE, covering agents.md — universal agent configuration template, 1. project identity (required variables), 2. operational commands, install dependencies and start development server.
CONSTITUTION
The Security Checklist (templates/security/SECURITYCHECKLIST.md) must be completed before every production release.
AGENTS
The core Agents SDK, published to npm as agents. This is the most complex package in the monorepo.
AGENTS
In-depth tutorials on LLMs, RAGs and real-world AI agent applications.
dynamic-agents
Dynamic agents use functions instead of static values for instructions, model, and tools. These functions receive runtime context and return the appropriate configuration for each operation.
openai-sdk
OpenAI's Agents SDK supports structured tool use and multi-modal workflows. ContextForge can serve as a unified tool registry for OpenAI agents.
