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 | $0.00403 | $0.00403 |
| Opus 5 | $0.00201 | $0.00201 |
| Sonnet 5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade A, and why
claude-aso-audit-skill 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 10d 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.
What it actually says
Claude ASO — App Store Optimization Skill Pack
Overview
Comprehensive ASO skill pack for iOS App Store and Google Play. One root audit router, 13 focused specialist skills, 10 specialist agents, and extensible API integrations. Follows the claude-seo 3-layer architecture (directive → orchestration → execution).
Architecture
aso/SKILL.md → Main orchestrator (entry point, routing, scoring)
skills/aso-*/SKILL.md → 13 focused specialist skills (independently invocable)
agents/aso-*.md → 10 specialist agents
references/*.md → On-demand knowledge (metadata specs, quality gates)
scripts/*.py → Python utilities (fetch, parse, validate, analyze)
extensions/ → Optional API integrations (AppTweak, App Store Connect)
Commands
All commands start with /aso. Run /aso for the full command table.
Development Rules
- SKILL.md files: <500 lines, <5000 tokens
- Reference files: focused, <200 lines
- Scripts: CLI interface with
--jsonoutput, docstrings - Naming: kebab-case for directories, snake_case for Python
- Agents: invoked via Agent tool, never via Bash
- Python: use uv, deps in pyproject.toml
- Platform detection: auto-detect iOS vs Android from app ID format
Key Principles
- Local-first:
/aso auditwith no args auto-detects Fastlane metadata, Xcode, or Gradle in the working directory - Platform-aware: Every analysis distinguishes iOS vs Android rules
- Parallel execution: Full audits spawn 7-9 subagents simultaneously
- Progressive disclosure: Metadata always loaded, references on demand
- Quality gates: Hard rules prevent bad recommendations (no keyword stuffing, respect char limits)
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.
