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 | $0.02713 | $0.02713 |
| Opus 5.5 | $0.01085 | $0.01085 |
| Sonnet 5.5 | $0.00543 | $0.00543 |
| Haiku 4.5 | $0.00271 | $0.00271 |
Grade A, and why
mcp-runtime AGENTS.md scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md — developer and AI-agent guide
This file is the onboarding index for the MCP Runtime repo. It complements README.md with where to look, build/CI conventions, and pointers to focused runbooks. Prefer repo source (README, CRDs, v1alpha1 types) over generic Kubernetes or MCP advice.
Operational detail lives in .codex/skills/ (symlinked from .claude/skills). Load the skill that matches your task instead of re-reading long checklists here.

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.

mcp-runtime AGENTS.md is an instructions file published in the GitHub repository Agent-Hellboy/mcp-runtime (6 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 2,713 tokens to every session, about $0.0109 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
