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 | $0.04141 | $0.04141 |
| Opus 5.5 | $0.01656 | $0.01656 |
| Sonnet 5.5 | $0.00828 | $0.00828 |
| Haiku 4.5 | $0.00414 | $0.00414 |
Grade A, and why
Youtube-Agent-Matrix CLAUDE.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 9d 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 — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Maintainer Guide
Guidance for anyone (human or agent) editing this plugin. The user-facing document is
README.md; this one is about how the thing is built and how to keep it coherent.
Architecture: three layers
Layer 1 skills/orchestrator/SKILL.md
Routing, startup sequence, state, gates, delegation contract.
Holds no domain knowledge and writes no deliverable.
│ delegates with an explicit prompt
▼
Layer 2 agents/*.md
16 subagents. Each owns its deliverable — two of them also own a
derived creator-facing view of it, see below. Agents do not call
each other; the orchestrator fans them out and collects results.
│ loads, on demand, only what it needs
▼
Layer 3 references/*.md + templates/channel-types/*.md + templates/outputs/*
Knowledge and shape. Inert: nothing here decides anything.
execution/*.py sits beside this layer as optional live data.
The separation is the point. Routing logic that leaks into an agent makes the agent unusable on its own. Domain knowledge that leaks into the orchestrator gets loaded on every single request. Benchmarks that leak into either one start drifting the moment the platform changes.
Which layer does a change belong in?
| The change is… | It goes in |
|---|---|
| When something runs, in what order, who approves | skills/orchestrator/SKILL.md |
| How one deliverable is produced and what it must contain | agents/<agent>.md |
| A fact, a rule, a framework, a mechanic | references/<topic>.md |
| A number | references/benchmarks.md, and nowhere else |
| Archetype-specific targets and patterns | templates/channel-types/<type>.md |
| The shape of a written deliverable | templates/outputs/ |
| Talking to an API | execution/ |
Hard authoring rules
1. SKILL.md stays under 500 lines. It loads on every invocation. Anything that is not
routing, state or gates belongs in a reference file. If it is growing, something has leaked down
from Layer 3 or up from Layer 2.
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.

Youtube-Agent-Matrix CLAUDE.md is an instructions file published in the GitHub repository PedroMeloOfficial/Youtube-Agent-Matrix (9 stars, last pushed 10d ago), licensed MIT. It adds 4,141 tokens to every session, about $0.0166 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 2026-08-31.
