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 | $0.00368 | $0.00368 |
| Opus 5.5 | $0.00147 | $0.00147 |
| Sonnet 5.5 | $0.00074 | $0.00074 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
stocksense 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 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.
What it actually says
CLAUDE.md
Project Overview
StockSense — an open-source MCP server providing AI agents with access to financial data (SEC filings, fundamentals, insider trades, price history).
Tech Stack
- Python 3.11+
- MCP SDK (
mcppackage) - SEC EDGAR API (free, no key needed)
- yfinance (price data)
- Financial Modeling Prep or Alpha Vantage (fundamentals)

Key Design Decisions
- All data sources are free or very cheap ($0-14/month)
- SEC EDGAR is the core differentiator (free, unlimited, rich data)
- Tools return structured data optimized for LLM consumption
- Caching layer to avoid redundant API calls
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.
