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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00788 | $0.00788 |
| Opus 5 | $0.00394 | $0.00394 |
| Sonnet 5 | $0.00158 | $0.00158 |
| Haiku 4.5 | $0.00079 | $0.00079 |
Grade A, and why
duragent AGENTS.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 3d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Project Context for AI Agents
Project Overview
Duragent — A durable, self-contained runtime for AI agents.
Sessions survive crashes. Agents are just files. One binary, zero dependencies.
Use it as a personal AI assistant, or as the foundation for agent-powered products.
Key Concepts
| Concept | Description |
|---|---|
| Session | Durable conversation context; survives crashes/disconnects; attach/detach like tmux |
| on_disconnect | continue (agent keeps working) or pause (waits for reconnect) |
| Core gateways | CLI, HTTP REST, SSE — built into Duragent |
| Platform gateways | Telegram, Discord — subprocess plugins via Gateway Protocol |
| Tools | bash, CLI tools, web search/fetch, scheduled tasks, background processes |
| Skills | Modular Markdown-based capabilities with frontmatter metadata |
| Memory | Per-agent recall/remember/reflect + shared world knowledge |
| Context management | Token budgeting, history truncation, priority-based rendering |
| Sandbox | Trust mode (no isolation) |
| Duragent Format | YAML + Markdown agent definitions |
Planned
- Sandbox isolation: bubblewrap (Linux), Docker (cross-platform)
- MCP tool integration
- Structured logging / metrics (OpenTelemetry)

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.

duragent AGENTS.md is an instructions file published in the GitHub repository giosakti/duragent (48 stars, last pushed 6mo ago), licensed MIT. It adds 788 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.
