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 | $0.00252 | $0.00252 |
| Opus 5 | $0.00126 | $0.00126 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
vastai-host-mcp yaml.instructions.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 10d 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.
What it actually says
YAML Instructions
YAML Content Rules
- Limit consecutive blank lines to one (yamllint
empty-lines). - Use spaces for indentation (2 spaces per level from .editorconfig); avoid tabs.
- Keep lines <=120 characters (yamllint
line-length). - End files with a newline (yamllint
new-line-at-end-of-file). - Use explicit booleans
true/false; avoid other truthy values (yamllinttruthy). - Keep list/map items in lexicographical order when practical.
- When embedding code blocks or inline YAML snippets inside lists, include a trailing newline to preserve indentation.
- Allow at most one space inside braces (yamllint
braces).
Validation
- Repository rules come from
.yamllint. - Run
pre-commit run yamllint -ato verify locally. - Use
yqfor parsing and validation of YAML files, especially for long or complex files:yq . file.yaml. - Find the right syntax for your YAML multiline strings
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.
