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 | $0.04199 | $0.04199 |
| Opus 5.5 | $0.01680 | $0.01680 |
| Sonnet 5.5 | $0.00840 | $0.00840 |
| Haiku 4.5 | $0.00420 | $0.00420 |
Grade C, and why
nova CLAUDE.md scanned grade C with 2 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Nova — Architecture & Conventions
Claude Code reads this file on every conversation. It describes how Nova actually works so you can navigate the codebase, make changes, and debug without re-exploring each time.
Nova is a multi-agent AI orchestration platform. 24 specialist agents, task decomposition with dependency resolution, human-in-the-loop approval gates, pattern caching, multi-channel messaging (Telegram/WhatsApp/Slack), and 12 MCP integrations.
For setup instructions, see SETUP.md. For production deployment, see DEPLOY.md. For deep technical reference, see docs/ARCHITECTURE.md.

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.

nova CLAUDE.md is an instructions file published in the GitHub repository djbelieny/nova (5 stars, last pushed 3mo ago), licensed MIT. It adds 4,199 tokens to every session, about $0.0168 per session on Opus 5.5. A static security scan graded it C with 2 findings (hidden instructions, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
