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 | $0.00422 | $0.00422 |
| Opus 5.5 | $0.00169 | $0.00169 |
| Sonnet 5.5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
aso-mcp-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 2mo 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.
This is a copy
86% identical to aso-skills AGENTS.md — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Agent Guidelines
This repo contains App Store Intelligence skills following the Agent Skills open standard, plus an MCP server for real-time data access.
Structure
src/worker.py — MCP server (Cloudflare Workers, Python)
skills/<name>/SKILL.md — Skill instructions (required, <500 lines)
skills/<name>/references/ — Detailed docs loaded on demand (optional)
tools/integrations/ — API integration guides (AppKittie)
tools/REGISTRY.md — Capability matrix: which skill uses which tool
Compatible directories: .cursor/skills/, .agents/skills/, .claude/skills/, .codex/skills/
SKILL.md Format
---
name: skill-name # Must match directory, lowercase+hyphens, 1-64 chars
description: ... # Trigger phrases + scope boundaries, 1-1024 chars
metadata:
version: 1.0.0
---
Description drives discovery — agent reads all descriptions to decide which skill to load. Include "When the user wants to...", trigger keywords, and "For X, see Y skill" boundaries.
Writing Style
- Direct, actionable, second person
- Tables for comparisons, numbered lists for steps
- Bold for key terms, code blocks for examples
- No filler, no hedging
App Store Reference
iOS limits: Title 30 chars, Subtitle 30 chars, Keyword field 100 chars (comma-separated, no spaces), Description 4000 chars (not indexed for search), Promotional text 170 chars.
Key rules: Title has highest keyword weight. Don't repeat keywords across fields. Use singular forms. Don't include "app" or category names in keyword field.

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.
