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

snek.test.generate 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 2mo 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

Generate Tests

Generate unit tests for a function or module.

Usage

User provides:

  • File path
  • Function name (optional - if not provided, generate tests for all public functions)

Steps

  1. Get file outline:
.snek/scripts/get-file-outline.sh "/path/to/file"

  1. Read the function(s) to understand:

    • Input parameters and types
    • Return type
    • Edge cases
    • Error conditions

  2. Generate tests covering:

    • Happy path (normal operation)
    • Edge cases (empty input, boundary values)
    • Error cases (invalid input, error conditions)

  3. Format tests for the language:

    • Rust: #[test] functions
    • Python: pytest functions
    • JavaScript/TypeScript: Jest/Mocha tests
    • Go: func TestXxx functions

  4. Present tests to user. If approved, write to appropriate test file location.

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.
