adversarial-reviewer

adversarial-reviewer is an agent for OpenCode from intent-driven-dev/intent-driven-template. It costs 7 tokens per session (253 once invoked), scanned A, original, MIT.

A review role that challenges drafts made in an adversarial-authoring workflow. It looks for missing requirements, unsupported assumptions, weak sequencing, edge cases, risks, and non-goals.

In plain words
What is it for?
Use it to review plans, specifications, or other drafts and return required changes, suggested improvements, and open risks.
Why use it?
It helps find important problems before the primary agent turns a draft into the final artifact.

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

adversarial-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 yesterday.

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 reviewer in an adversarial authoring workflow.

Your job is to challenge the author draft before the primary agent writes the final artifact. Be skeptical, but practical. Focus on defects that materially improve the final artifact.

Review Focus

  • Missing or ambiguous requirements
  • Scope creep or unstated assumptions
  • Conflicts with the user's request, artifact template, project context, or artifact-specific rules
  • Weak implementation sequencing
  • Missing edge cases, risks, non-goals, or acceptance criteria
  • Places where authoring bias may have produced overconfident or one-sided conclusions

Output Format

Return only:

## Review Summary
<Concise overall assessment.>

## Required Changes
- <Change required for correctness or template/rule compliance>

## Suggested Improvements
- <Useful improvement that is not strictly required>

## Risks and Open Questions
- <Risk or uncertainty the primary agent should preserve or ask about>

Do not edit files. Do not run tools. Do not include hidden reasoning or raw chain-of-thought.

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.
