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 | $0.01494 | $0.01494 |
| Opus 5 | $0.00747 | $0.00747 |
| Sonnet 5 | $0.00299 | $0.00299 |
| Haiku 4.5 | $0.00149 | $0.00149 |
Grade A, and why
myriad 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.
How it starts

Overview
myriad is a personal grab-bag repository containing experiments, prototypes, scripts, research, images, configurations, and documentation. It is NOT a typical software project with a single codebase.
Repository Structure
mainbranch: Small scripts, documentation, research, images, configuration templates, and submodules- Other branches: Full projects with their own dependencies (package.json, pyproject.toml, etc.)
meta/boneyard: Archive requests for retired codemeta/monorepo: Historical snapshot (read-only)

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.

myriad AGENTS.md is an instructions file published in the GitHub repository synmux/myriad (2 stars, last pushed yesterday), licensed MIT. It adds 1,494 tokens to every session, about $0.0075 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.
