alpha-judge

alpha-judge is a skill for Claude Code from tonydzi/second-brain-starter-kit. It costs 108 tokens per session (2,321 once invoked), scanned A, original, MIT.

A shared language-model review step for an alpha-extraction system, where smaller detectors first find possible signals and this reviewer keeps the real ones.

In plain words
What is it for?
Reviewing candidates from multiple alpha miners, rejecting false signals, and suggesting additional candidates for each miner.
Why use it?
It removes repeated review logic and helps filter noisy candidate lists before they are reported or calibrated.

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

alpha-judge 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 8d 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.

🅰️⚖️ /alpha-judge — the reusable LLM-judge for every alpha miner

🧒 When reporting to a non-technical operator: end with a child-simple "In plain words" recap in their language (their standing request; reports TO the operator only).

The alpha-extraction engine = cheap deterministic detector (0 tokens) → LLM judge → weekly ≤10 + yes/no calibration, repeated for each of the 10 miners. The DETECTORS are per-miner scripts in $IMPORTS_ROOT/alpha/. The JUDGE is the SAME logic every time — so it lives HERE, once, and is reused. Canon: 02-Decisions\decision-alpha-extraction-engine-variant-a; memory [[alpha-extraction-engine]].

Model policy (per [[model-routing-sonnet-grunt]] + the operator's 2026-06-14 session override)

  • In-session, now: judge on Opus (the operator steers; he'll say when to switch to Sonnet as Opus nears its limit).
  • Nightly unattended: Sonnet (idle free bucket) via judge_nightly.cmd (headless claude -p --model sonnet). LIVE + verified 2026-06-15 — Windows task "Alpha Judge Nightly" Mon 05:00, chained after the 04:15 scan. Now judges ALL 10 miners (was bets-only; expanded 2026-06-15) — one headless session reads THIS spec, loops the registry, applies the dedup-vs-home gate, writes each <miner>-judged-latest.md. Vault writes are forbidden in nightly mode (judge-only; home-note additions wait for the operator's in-session approval). (Auth is in the Windows keychain; check with claude auth status, re-login via claude auth login. Keep .cmd pure-ASCII.)
  • The judge is grunt-classification → Sonnet is the natural default once the session-override lifts.

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.

alpha-judge is a skill published in the GitHub repository tonydzi/second-brain-starter-kit (5 stars, last pushed 9d ago), licensed MIT. It adds 108 tokens to every session and 2,321 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
