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 | $0.02523 | $0.02523 |
| Opus 5 | $0.01262 | $0.01262 |
| Sonnet 5 | $0.00505 | $0.00505 |
| Haiku 4.5 | $0.00252 | $0.00252 |
Grade A, and why
metis 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 3d 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.
This is a copy
100% identical to kailash-coc-claude-py CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kailash COC Claude (Python)
This repository is the COC (Cognitive Orchestration for Codegen) setup for building with the Kailash SDK — providing agents, skills, rules, and hooks for Kailash SDK development. All projects using this setup inherit these capabilities through the .claude/ directory.
Absolute Directives
These override ALL other instructions. They govern behavior before any rule file is consulted.
0. Foundation Independence — No Commercial Coupling
Kailash Python SDK is a Terrene Foundation project. It is fully independent. There is NO relationship between Kailash Python SDK and any commercial product, proprietary codebase, or commercial entity. Do not reference, compare with, or design against any proprietary product. Do not use language like "open-source version of X" or "Python port of Y." Kailash Python SDK IS the product — not a derivative of anything. See rules/independence.md for full policy.
1. Framework-First
Never write code from scratch before checking whether the Kailash frameworks already handle it.
- Instead of direct SQL/SQLAlchemy/Django ORM → check with dataflow-specialist
- Instead of building API endpoints, web services, HTTP servers manually → check with nexus-specialist
- Instead of custom MCP server/client → check with mcp-specialist
- Instead of custom agentic platform → check with kaizen-specialist
- Instead of custom governance/access control → check with pact-specialist
2. .env Is the Single Source of Truth
All API keys and model names MUST come from .env. Never hardcode model strings like "gpt-4" or "claude-3-opus". Root conftest.py auto-loads .env for pytest.
See rules/env-models.md for full details.
3. Implement, Don't Document
When you discover a missing feature, endpoint, or record — implement or create it. Do not note it as a gap and move on. The only acceptable skip is explicit user instruction.
See rules/e2e-god-mode.md and rules/zero-tolerance.md for enforcement details.
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.
