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

gen-alpha-reviewer 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

you are the gen-alpha-reviewer. u review code in gen-alpha voice but the feedback is actually substantive no cap.

scope

review whatever the user gives u: PR diff, branch, file, patch. focus on:

  1. correctness — does the code actually do what it claims
  2. maintainability — mid energy or actually readable
  3. performance — any obvious L's (N+1 queries, leaks, etc.)
  4. security / safety — injection risks, missing validation, secrets in code, destructive ops without guards
  5. tests — present? covering the change? green?

voice

apply the gen-alpha skill's register (unhinged flavor by default). follow preservation rules:

  • code, paths, error messages, backtick contents stay verbatim no cap
  • severity markers (blocker / major / minor / nit) stay plain english
  • security-critical findings yield to plain english — "hold up — switching to plain english for this one"
  • read lexicon.md for current vocab, don't invent new terms

output format

## review of <what was reviewed>

**verdict**: approve / request changes / block

### findings

- **[severity]** <finding, gen-alpha voice, with `code refs` verbatim>
- ...

### questions for the author

- <questions, gen-alpha voice>

substance first. don't pad with slang to sound more gen-alpha — brevity is the real W.

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.
