adversarial-persona

adversarial-persona is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 37 tokens per session (755 once invoked), scanned A, original, Apache-2.0.

A review method that tests work from the viewpoint of hostile or skeptical people, such as a competing researcher, a reviewer, or someone outside the field.

In plain words
What is it for?
Use it to challenge research proposals, technical plans, funding cases, or other work that needs critical review.
Why use it?
It helps expose weak methods, unsupported claims, unrealistic plans, hidden assumptions, and unclear language before others find them.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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-persona 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 11d 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.

Adversarial Persona Strategy

Construct and deploy hostile personas that attack from distinct motivational frames. Each persona has unique expertise, biases, and attack patterns.

Method

  1. persona-construction builds detailed adversary profiles (background, motivation, expertise, blind spots)
  2. Each persona attacks from their specific frame:
    • Hostile Reviewer: methodological rigor, statistical validity, novelty claims
    • Competing Lab: priority disputes, alternative approaches, resource efficiency
    • Funding Skeptic: impact claims, feasibility, timeline realism
    • Domain Outsider: jargon opacity, unstated assumptions, accessibility
  3. probe-execution executes persona-specific attacks
  4. Cross-persona findings compared to identify convergent vulnerabilities
  5. finding-aggregation synthesizes across all persona perspectives

Budget Table

Parameter S M L
Attack vectors 5 12 20
Probing rounds 3 6 10
Personas 2 4 6
Assumption checks 5 10 20

Orchestration

persona-construction → [build N personas per budget]
→ [for each persona]:
    attack-vector-generation (persona-specific vectors)
    → probe-execution (execute persona attacks)
→ finding-aggregation (cross-persona synthesis)
→ attack-resilience-scoring

Subagents

  • persona-construction (adversary profile building)
  • attack-vector-generation (persona-specific attack design)
  • probe-execution (persona attack execution)
  • finding-aggregation (cross-persona synthesis)
  • attack-resilience-scoring (convergent vulnerability scoring)

Available Tactics

Optional, no fixed order; the final leaf is always a sop.

Tactic When to use
adversarial-roleplay Tactic: Construct detailed hostile persona, attack artifact from that persona's perspective, record successful attack paths for aggregation.
structured-attack-campaign Tactic: Full attack lifecycle — threat surface enumeration, attack vector generation, systematic probing, and finding aggregation across all surfaces.

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.
