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 | $0.00248 | $0.00248 |
| Opus 5 | $0.00124 | $0.00124 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
helmo 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 4d 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.
What it actually says
AGENTS — session routing for helmo
Canonical apparatus file (vendor-neutral). CLAUDE.md is a shim pointing here.
The context envelope is a design decision: what a session does NOT load is part
of its role.
What kind of session is this?
- Summoned role — any request to "summon the helmo orchestrator", run a
meeting, or work the awaiting-human queue: read
HELMO-ORCHESTRATOR.mdwhole, to its last line, and reproduce its canary line before addressing any agenda. Read nothing else in this repo — not DEV.md, not src/. A meeting role that ingested the codebase is a worse meeting role. - Coding / dev session — working on Helmo itself: read
DEV.md, then go. - Agent using Helmo as a tool (MCP or CLI from anywhere else): the tool descriptions are self-sufficient; read nothing here.
Universal expectations
- Work is tracked in Helmo itself: claim before working, note progress when reality changes, close with evidence — the artifact, not a claim about it.
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.

helmo AGENTS.md is an instructions file published in the GitHub repository arthurcoulston/helmo (0 stars, last pushed 2d ago), licensed MIT. It adds 248 tokens to every session, about $0.0012 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 2026-08-31.
