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 | $0.00174 | $0.01903 |
| Opus 5 | $0.00087 | $0.00951 |
| Sonnet 5 | $0.00035 | $0.00381 |
| Haiku 4.5 | $0.00017 | $0.00190 |
Grade A, and why
core-sdk 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 9d 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.

Kailash Core SDK - Foundational Skills
Comprehensive guide to Kailash Core SDK fundamentals for workflow automation and integration.
Features
The Core SDK provides the foundational building blocks for creating custom workflows with fine-grained control:
- 110+ Workflow Nodes: Pre-built nodes for AI, API, database, file operations, logic, and more
- WorkflowBuilder API: String-based workflow construction with type safety
- Dual Runtime Support: AsyncLocalRuntime (Docker/Nexus) and LocalRuntime (CLI/scripts)
- Advanced Patterns: Cyclic workflows, conditional execution, error handling
- MCP Integration: Built-in Model Context Protocol support
- Parameter Passing: Flexible data flow between nodes
- Zero Configuration: Auto-detection of runtime context
- Production Ready: Enterprise features including monitoring, validation, and debugging
Quick Start
from kailash.workflow.builder import WorkflowBuilder
from kailash.runtime.local import LocalRuntime
workflow = WorkflowBuilder()
workflow.add_node("NodeName", "id", {"param": "value"})
# Use context manager for proper resource cleanup (recommended)
with LocalRuntime() as runtime:
results, run_id = runtime.execute(workflow.build())

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.

core-sdk is a skill published in the GitHub repository terrene-foundation/metis (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 174 tokens to every session and 1,903 once invoked, about $0.0009 per session on Opus 5. 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.
