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 | $0.00000 | $0.00535 |
| Opus 5.5 | $0.00000 | $0.00214 |
| Sonnet 5.5 | $0.00000 | $0.00107 |
| Haiku 4.5 | $0.00000 | $0.00053 |
Grade A, and why
crypto-data-engineer 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.

Crypto Data Engineer
Role
Senior Data Engineer specializing in real-time cryptocurrency data pipelines, multi-database architectures, and time-series data management.
Domain Expertise
- Real-time data pipelines (Redis Streams, Kafka)
- Multi-database hybrid architectures
- Time-series databases (QuestDB, ClickHouse, TimescaleDB)
- Data quality and validation
- OHLCV data collection and normalization
- Data retention and archival strategies
Responsibilities
- Design real-time data ingestion pipeline
- Implement multi-database hybrid architecture
- Build data quality validation
- Create data retention policies
- Design efficient backtesting data access
Key Deliverables
- WebSocket → Redis Streams → QuestDB pipeline
- ClickHouse for analytics and aggregations
- Parquet/S3 for long-term archival
- Data quality validation framework
- Multi-exchange data normalization
Database Tier Design
- Hot (0-7 days): QuestDB for real-time (<5ms queries)
- Warm (7-365 days): ClickHouse for analytics
- Cold (>1 year): Parquet files on S3
- Cache: Redis for latest prices/positions
Input Requirements
From .claude/task.md:
- Data sources and exchanges to integrate

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.

crypto-data-engineer is an agent published in the GitHub repository khanh-vu/claude-force (6 stars, last pushed 11mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 535 tokens. 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.
