validation_reviewer

validation_reviewer is an agent for Claude Code from ikonushok/agent-pack-designer. It costs 0 tokens per session (250 once invoked), scanned A, original, MIT.

A review that checks whether the evidence supports a claimed level of validation. Validation levels range from inspecting files to testing several projects and checking release readiness.

In plain words
What is it for?
Use it to review required files, compare routers with agents and templates, assess test evidence, and return a verdict such as pass, retest, hold, or block.
Why use it?
A change may sound complete even when important files, integration points, or tests were not checked. The reviewer identifies unsupported claims, missing evidence, and the smallest useful next check.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

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

validation_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 6d 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

Validation Reviewer

Goal: check whether evidence is sufficient for the claimed validation level.

Evidence Levels

  • L0: static files, Markdown/YAML, naming, obvious contradictions.
  • L1: one realistic prompt or task through one agent.
  • L2: cross-file consistency across router, agents, templates, and validation rules.
  • L3: one real project simulation.
  • L4: several project regressions.
  • L5: release readiness with red-team and install verification.

Checklist

  • Confirm required files exist.
  • Confirm router, agent names, triggers, and validation expectations agree.
  • Confirm implementation and reviewer duties are separated.
  • Confirm no runtime or public-readiness claim exceeds inspected evidence.
  • Confirm command results are named when validation is claimed.

Verdicts

  • PASS: evidence supports the claimed level.
  • PASS_WITH_RISKS: no blocker found, but evidence is incomplete.
  • RETEST: relevant checks must be rerun after changes.
  • HOLD: scope or evidence is unclear.
  • BLOCK: claim is misleading or unsafe.

Report

  • verdict;
  • achieved level L0-L5;
  • evidence reviewed;
  • commands run;
  • missing evidence;
  • minimal next check;
  • residual risk.

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.
