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 | $0.01987 | $0.01987 |
| Opus 5.5 | $0.00795 | $0.00795 |
| Sonnet 5.5 | $0.00397 | $0.00397 |
| Haiku 4.5 | $0.00199 | $0.00199 |
Grade A, and why
holon 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 6d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Holon is a headless, event-driven runtime for long-lived agents, with web and
native clients. Keep the codebase small, explicit, and easy to reason about.
Project Structure & Module Organization
src/: Rust runtime implementation and executable entrypoints.crates/: supporting Rust crates, including decision and model-client code.tests/: Rust integration tests and shared test support.builtin_templates/: runtime-managed agent templates.agent_templates/: checked-in role templates and their agent guidance.packages/: shared API, App, conversation, and native-client SDK/wire packages.web-gui/: web client and OpenAPI generation/check tooling.apps/: native Android, iOS, and macOS clients.benchmark/andbenchmarks/: benchmark harness, fixtures, suites, and task manifests.docs/: current runtime contracts, architecture notes, and design records.holonbot/: Node-based GitHub App/bot retained as a separate service asset.skills/: repository skills and task workflows.README.mdandREADME.zh-CN.md: public-facing project definition.CONTRIBUTING.md,Makefile, and.github/workflows/: contributor workflow and verification entrypoints.
Do not introduce large framework scaffolding before the runtime model is clear.
Product Intent
Holon is meant to be:
- headless
- event-driven
- long-lived
- explicit about trust boundaries
- explicit about user-facing versus internal output
When design choices conflict, prefer runtime clarity over convenience.
Development Priorities
Prioritize work in this order:
- Runtime model and message envelope.
- Queue, wake, sleep, and task lifecycle.
- Event ingress and trust classification.
- Structured user-facing output.
- Integrations and adapters.
Do not start with UI work unless the task explicitly requires it.
Autonomous Issue Selection
When the operator authorizes an agent to choose issues autonomously, use these maintainer-controlled labels as an opt-in candidate pool. This is a repository policy, not an implemented runtime permission gate.
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.

holon AGENTS.md is an instructions file published in the GitHub repository holon-run/holon (194 stars, last pushed yesterday), licensed Apache-2.0. It adds 1,987 tokens to every session, about $0.0079 per session on Opus 5.5. 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.
