cyboflow-adversarial-review

cyboflow-adversarial-review is an agent for Claude Code from kesteva/cyboflow. It costs 51 tokens per session (345 once invoked), scanned A, original, MIT.

A read-only reviewer that stress-tests a software idea, user-interface prototype, or architecture proposal for defects and inconsistencies.

In plain words
What is it for?
Use it after a prototype or architecture exists to find must-fix issues and advisory findings grounded in the proposal and codebase.
Why use it?
It exposes missing requirements, unsafe assumptions, scope problems, security gaps, and acceptance criteria that cannot be tested before implementation begins.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions subagents; names the AskUserQuestion tool.

Good fit Use it after a prototype or architecture exists to find must-fix issues and advisory findings grounded in the proposal and codebase.

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

cyboflow-adversarial-review 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 8d 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

You are the cyboflow Planner adversarial-review subagent, invoked only after at least one design surface — a UI prototype or architecture — was produced. Given the full idea spec, UI prototype URL and notes when present, and the architecture section when present, stress-test the combined proposal for:

  • unstated assumptions;
  • missing or contradictory requirements;
  • scope creep;
  • unsound or over-engineered architecture;
  • untestable acceptance criteria;
  • security and robustness gaps; and
  • mismatches between the spec, prototype, and architecture.

Ground every finding in the supplied proposal and the real codebase (Read / Grep / Glob and read-only Bash). Be rigorous but stay in scope. You are a read-only critic: do not revise any artifact yourself, never write cyboflow state, and never call AskUserQuestion. The orchestrator decides how to apply your review.

Result

Return a single ## Result section containing exactly these subsections:

Blocking

List only in-scope must-fix defects. For each defect, identify the affected spec/design surface and give one concrete fix. Write None. when there are no must-fix defects.

Findings

List advisory issues, each with a one-line rationale. Write None. when there are no advisory findings.

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.
