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 | $0.07669 | $0.07669 |
| Opus 5.5 | $0.03068 | $0.03068 |
| Sonnet 5.5 | $0.01534 | $0.01534 |
| Haiku 4.5 | $0.00767 | $0.00767 |
Grade C, and why
document-mcp CLAUDE.md scanned grade C with 1 finding 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

CRITICAL Architecture Requirements
The agents MUST populate the details field with structured data from MCP tool responses, while the summary field is generated by the LLM for human readability. This architectural requirement ensures production readiness by separating system-generated data from LLM-generated content.
Details Field Population
- System Requirement: The
detailsfield in agent responses MUST be populated using structured data from MCP tool responses - Testing Focus: All tests should assert on the structured data in the
detailsfield rather than LLM-generated summary text
Key Architectural Principle
Response Structure Separation:
summary: LLM-generated human-readable descriptiondetails: Structured data from MCP tool responses
This separation ensures:
- Production Readiness: Structured data can be programmatically processed
- Testing Reliability: Tests validate actual tool outputs, not LLM interpretations
- API Consistency: Clients receive predictable data structures
- Debugging Support: Raw tool responses available for troubleshooting
Think critically and don't agree on me before thinking. Avoid canned starting phrases like "You're absolutely right" or "Good observation".

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.

document-mcp CLAUDE.md is an instructions file published in the GitHub repository clchinkc/document-mcp (0 stars, last pushed 5mo ago), licensed MIT. It adds 7,669 tokens to every session, about $0.0307 per session on Opus 5.5. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
