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 | $0.00030 | $0.01865 |
| Opus 5 | $0.00015 | $0.00932 |
| Sonnet 5 | $0.00006 | $0.00373 |
| Haiku 4.5 | $0.00003 | $0.00186 |
Grade A, and why
error-troubleshooting 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 6d 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
94% identical to error-troubleshooting — 6 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.

Kailash Error Troubleshooting
Common error patterns and solutions for Kailash SDK.
When to Use
Use when encountering errors, debugging issues, or asking about error, troubleshooting, debugging, not working, hangs, timeout, validation error, connection error, runtime error, cycle not converging, missing build, or template syntax. Covers Nexus blocking issues, connection parameter errors, runtime execution errors, cycle convergence problems, missing .build() calls, parameter validation errors, and DataFlow template syntax errors.

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.

error-troubleshooting is a skill published in the GitHub repository terrene-foundation/metis (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 1,865 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to error-troubleshooting, differing in 6 lines, and is treated as a copy.
