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 | $0.00034 | $0.01056 |
| Opus 5 | $0.00017 | $0.00528 |
| Sonnet 5 | $0.00007 | $0.00211 |
| Haiku 4.5 | $0.00003 | $0.00106 |
Grade A, and why
gold-standards 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 11d 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 Gold Standards - Mandatory Best Practices
These are required patterns that prevent bugs, ensure consistency, and maintain code quality.
When to Use
Use gold-standards when asking about best practices, standards, gold standards, mandatory rules, required patterns, absolute imports, testing policy, error handling standards, security best practices, documentation standards, or workflow design standards. Covers absolute imports, parameter passing, error handling, Tier 2/3 testing with real infrastructure (NO mocking per rules/testing.md), workflow design, custom node development, security, documentation, and test creation.
Sub-File Index
Code Organization
- gold-absolute-imports - ALWAYS absolute, NEVER relative
from kailash.workflow.builder import WorkflowBuilder(notfrom ..workflow import builder)
- gold-parameter-passing - 4-parameter connections + dict result access
workflow.add_connection(source_id, source_param, target_id, target_param)results["node_id"]["result"](notresults["node_id"].result)
Testing
- gold-mocking-policy - Real infrastructure in Tiers 2-3
- Mocking ONLY in Tier 1 unit tests; Tiers 2-3 use real databases, APIs, infrastructure
- gold-testing - 3-tier strategy, deterministic tests, resource cleanup
- gold-test-creation - TDD, one assertion focus, AAA pattern
- Release-blocking regression tier (W33b) — every public km.* surface has a fingerprint test + an e2e
execute(...)pattern that round-trips from workflow → node → engine → registry. See skill 34-kailash-ml for the exact contract. Release PRs block on this tier independently of unit/integration status.
Error Handling
- gold-error-handling - Explicit handling, no silent swallowing, actionable messages, cleanup in

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.

gold-standards is a skill published in the GitHub repository terrene-foundation/metis (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 34 tokens to every session and 1,056 once invoked, about $0.0002 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.
