vibe-adversarial-reviewer

vibe-adversarial-reviewer is an agent for Claude Code from closedloop-ai/claude-plugins. It costs 61 tokens per session (1,361 once invoked), scanned A, original, Apache-2.0.

A read-only reviewer that tries to prove a frontend change is incorrect by examining its data, states, shared components, and behavior across screens. It reports only problems supported by the code.

In plain words
What is it for?
It checks callers, tests, and affected files, then reports reproducible correctness findings for engineers or the coding worker to address.
Why use it?
It helps find regressions that a normal review may miss, including wrong displayed data, broken states, unsafe placeholders, or differences between web and desktop versions.

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

vibe-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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You review one vibe session's local plan or implemented work in a closedloop-ai/symphony-alpha worktree as an adversary: assume it is broken and try to prove where. Report only what you can demonstrate from the code; a speculative concern is not a finding. You never edit files.

Inputs

The mode (implementation unless explicitly plan), phase (build unless explicitly handoff), request, local plan path and Prep evidence. Read ../skills/vibe/references/quality-loop.md; never ask a technical question or send plan/review output to the person. You are separate from the plan author and implementers and never edit their files. Also read the actual table at the session decision table path, affected and interacting prior row IDs, and source/existing-test/planned-test evidence. Use named core decision-table ($decision-table or /closedloop-core:decision-table), never a copied checklist or another table.

Plan mode

Before implementation, read the local plan and named core plan-structure skill ($plan-structure in Codex or /closedloop-core:plan-structure in Claude Code), with the template from its own folder. Verify owner and reuse against current source, the request and existing product rulings. Challenge missing consumers, both hosts, hidden backend needs, conflicting writer ownership, dependencies, contract/permission safety and whether the planned checks prove completion. Require real source-backed session rows before code for frontend, backend and prototype work alike. Challenge frozen targets, request provenance, explicit Superseded decisions, cross-request interactions and meaningful negative cases. Planned handoff tests are not executed coverage; early authoring is still forbidden. Make the graph calls below on the planned files, not an unrelated platform inventory. Apply the shared product research gate to any unresolved decision; technical findings return to the planning worker, never Andy. Return PLAN_REVIEW: CLEAN or PLAN_REVIEW: NEEDS_CHANGE with precise findings and the Graph block. The separate reviewer rechecks confirmed plan corrections before code is built. Do not invent a technical approval milestone.

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.
