Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

vastai-host-mcp AGENTS.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.

Specialized Agents

For specific tasks, use the following specialized agent instructions:

Common Tasks

Before each commit

  • Verify your expected changes with git diff --no-color.
  • Use the project linting/validation tools to confirm your changes meet the coding standard.
  • If the repo uses git hooks, run them to validate your changes.

Linting and Validation

# Run all pre-commit checks
pre-commit run -a

# Run specific checks
pre-commit run markdownlint -a
pre-commit run yamllint -a

Understanding the Task

  • When the task is not clear, look for additional context.
  • If triggered by a brief comment, check whether the parent comment exists and includes more detail.
  • If it's still ambiguous, communicate with the user and propose options.

Changes

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.
