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 | $0.01220 | $0.01220 |
| Opus 5.5 | $0.00488 | $0.00488 |
| Sonnet 5.5 | $0.00244 | $0.00244 |
| Haiku 4.5 | $0.00122 | $0.00122 |
Grade A, and why
x-algorithm-skills 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 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.
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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
🤖 Agent Integration Guide
This repository follows the Agent Skills Standard, a specification for providing AI agents with domain-specific "expertise" through structured documentation and reference material.
While optimized for Claude Code via its native plugin system, this repository is designed to be "Agent Agnostic"—working seamlessly with Cursor, GitHub Copilot, Windsurf, Roo Code, and custom LLM implementations.
🧠 Core Agent Personas
Following the Vercel Agent Skills model, we categorize our skills into specialized personas.
You can "summon" these personas by providing the corresponding SKILL.md files to your agent.

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.

x-algorithm-skills AGENTS.md is an instructions file published in the GitHub repository ElemontCapital/x-algorithm-skills (2 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 1,220 tokens to every session, about $0.0049 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.
