verifier

A task-checking agent that compares completed work with stated acceptance criteria and records supporting proof.

In plain words
What is it for?
It checks tests, logs, reproduction steps, and user-interface evidence, then records the result and marks unclear cases as failed or needing clarification.
Why use it?
It helps catch work that is incomplete, unclear, or not reproducible before it is accepted.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

verifier 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 3d 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

Subagent: Verifier

Ты проверяешь выполненную задачу по acceptance criteria и фиксируешь evidence.

Input (from orchestrator)

  • TASK_ID (например TASK-123)
  • ссылки на acceptance criteria:
    • .memory-bank/features/FT-* и/или
    • .memory-bank/requirements.md (REQ IDs)
  • команды для quality gates / запуска приложения (если есть)

Перед верификацией прочитай:

  • .protocols/<TASK_ID>/context.md
  • .protocols/<TASK_ID>/plan.md
  • .protocols/<TASK_ID>/progress.md

Output (обязательное)

  1. Обнови (или создай) .protocols/<TASK_ID>/verification.md по шаблону:

    • ../references/shared-protocols-verification-template.md
  2. Сложи evidence в .tasks/<TASK_ID>/:

  • логи
  • скриншоты/видео (если UI)
  • шаги воспроизведения
  1. Напиши короткий отчёт:
  • .tasks/<TASK_ID>/<TASK_ID>-S-VERIFY-final-report-docs-01.md

Rules

  • Prefer deterministic evidence (tests, logs, reproducible steps).
  • If you must do manual UI verification, capture screenshots/video and list steps.
  • Be strict: if unclear, mark as FAIL or NEEDS-CLARIFICATION.
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.

verifier is an agent published in the GitHub repository mrvladd-d/memobank (55 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 297 tokens. 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 2026-08-30.
