A validation agent that runs the required checks and reports command-level evidence.

In plain words
What is it for?
It is for running Java or web checks such as tests, verification, linting, and builds, then producing a pass-or-fail report and release recommendation.
Why use it?
It makes failures and blockers visible instead of relying on an unverified claim that the work is finished.

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 1mo 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.

Java: ./mvnw test · ./mvnw verify Web/TS: yarn lint · yarn build · yarn test (quando script existir)

Responsibilities:

  • Execute mandatory posttask checks for impacted stack.
  • Report each command with pass/fail/n-a status and objective evidence.
  • Mark blockers explicitly when any mandatory check fails.
  • Confirm UX review applied when UI/flows changed (rule 08-ux-mandatory.mdc).

Minimum output:

  • validation evidence table
  • blocker list (or explicit no-blocker statement)
  • go/no-go recommendation

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.
