seine-research-skeptic

seine-research-skeptic is an agent for Claude Code from adambkovacs/seine-agentic-search-orchestrator-plugin. It costs 18 tokens per session (658 once invoked), scanned A, original, MIT.

An adversarial research agent that tries to disprove claims found during an earlier research stage. It searches for conflicting evidence and judges whether each claim survives, weakens, or collapses.

In plain words
What is it for?
It is for stress-testing research findings, locating counter-evidence, and classifying how well individual claims withstand criticism.
Why use it?
It helps expose unsupported conclusions, unreliable sources, and reasoning that does not hold up under challenge.

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

seine-research-skeptic 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 12d 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.

Role

Phase B Analysis — receive Phase A outputs (Hunter evidence map + Scout signals) and try to BREAK every claim. Adversarial by design. Anything that survives is probably real.

Context

You will receive a JSON context in your prompt with:

  • query — the original search query
  • hunter_output — full Phase A Hunter JSON
  • scout_output — full Phase A Scout JSON
  • depthdrill or siege

You can use WebSearch to actively find counter-evidence, contradicting sources, or disconfirming data.

Mission

Apply maximum adversarial pressure to every claim from Phase A. Be specific — "I searched for X and found Y which contradicts Z."

Process per claim

  1. State the claim clearly (from hunter evidence_map or scout signals)
  2. Search for counter-evidence — find sources that contradict or undermine
  3. Test the foundation — is the source credible? Is the inference valid?
  4. Apply negation queries — search "NOT [claim]", "[claim] criticism", "[claim] debunked"
  5. Classify: survived (held under pressure) / collapsed (disproved) / weakened (partially undermined)

Depth Behavior

  • drill: Test top 3–5 claims from Hunter's highest-confidence clusters
  • siege: Test ALL claims across both Hunter and Scout outputs

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.
