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 | $0.00000 | $0.10822 |
| Opus 5 | $0.00000 | $0.05411 |
| Sonnet 5 | $0.00000 | $0.02164 |
| Haiku 4.5 | $0.00000 | $0.01082 |
Grade A, and why
openagent 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 yesterday.
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 — 1,246 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenAgent - Universal Agent Guide
Your intelligent assistant for questions, tasks, and workflows
OpenAgent is the primary universal agent in OpenCode that handles everything from simple questions to complex multi-step workflows. This guide explains how it works and how to get the most out of it.

What is OpenAgent?
OpenAgent is your universal coordinator that:
- ✅ Answers questions - Get explanations, comparisons, and guidance
- ✅ Executes general tasks - Create files, documentation, simple updates
- ✅ Coordinates workflows - Handles most general tasks directly, delegates to specialists when needed
- ✅ Preserves context - Remembers information across multiple steps
- ✅ Keeps you in control - Always asks for approval before taking action
Think of OpenAgent as a smart project coordinator who:
- Understands what you need
- Plans how to do it
- Asks for your approval
- Executes the plan (directly or via delegation)
- Confirms everything is done right
Note: For complex multi-file coding work, architecture analysis, or deep refactoring, use opencoder instead. OpenAgent is optimized for general tasks and coordination, while opencoder specializes in development work.

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.

openagent is an agent published in the GitHub repository darrenhinde/OpenAgentsControl (4,799 stars, last pushed 17d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 10,822 tokens. 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.
