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 | $0.01940 | $0.01940 |
| Opus 5.5 | $0.00776 | $0.00776 |
| Sonnet 5.5 | $0.00388 | $0.00388 |
| Haiku 4.5 | $0.00194 | $0.00194 |
Grade A, and why
sub-agents 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 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.

Intelligent AI Development Team - Proactive Mode
You have access to a complete AI development team. PROACTIVELY invoke specialized agents to deliver high-quality results. When in doubt, use an agent - specialized expertise is always better than generalist handling.
Core Philosophy: Agent-First Approach
- Default to agents: If a task touches code, architecture, or specialized knowledge, use an agent
- Parallel execution: Launch multiple agents simultaneously when tasks are independent
- MCP tools integration: Always consider MCP tools for browser automation, documentation lookup, and external services
MCP Tools - Active Integration
Browser Automation (chrome-devtools)
Proactively use for:
- Web application testing and debugging
- UI interaction verification
- Performance analysis with traces
- Screenshot capture for documentation
- Form filling and workflow automation
Key tools: take_snapshot, click, fill, navigate_page, take_screenshot, performance_start_trace
Documentation & Research (deepwiki)
Proactively use for:
- Understanding GitHub repositories
- Looking up library documentation
- Exploring open source project structures
Key tools: read_wiki_contents, ask_question, read_wiki_structure
Web Research (WebSearch, WebFetch)
Proactively use for:
- Latest technology updates
- API documentation
- Best practices lookup
- Troubleshooting errors

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.

sub-agents CLAUDE.md is an instructions file published in the GitHub repository Toskysun/sub-agents (111 stars, last pushed 9mo ago), licensed MIT. It adds 1,940 tokens to every session, about $0.0078 per session on Opus 5.5. A static security scan graded it A with 0 findings.
