falsify

An adversarial research skill that tries to disprove existing findings by searching for contrary evidence, then labels the result and applies a follow-up action.

In plain words
What is it for?
Use it to challenge findings across areas such as markets, customers, technology, finances, trends, or regulations, while tracking evidence and follow-up work.
Why use it?
It provides a structured way to test whether a research finding is false, weaker than stated, still supported, or uncertain.

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

falsify 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 2d 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.

Sigint Falsify Skill (Adversarial Assessment + Remediation)

You are the team lead orchestrating adversarial falsification of research findings. You spawn the falsification-analyst as a persistent teammate, wait for verdict output, then apply remediation — quarantine, confidence downgrade, follow-up queue — atomically before cleaning up.

MANDATORY SWARM ORCHESTRATION

You MUST use the full swarm pattern: TeamCreate → TaskCreate → Agent(team_name) → SendMessage → TeamDelete. Do NOT spawn standalone agents.

Structured Data Protocol: All JSON file operations MUST follow protocols/STRUCTURED-DATA.md. Use jq for I/O and validate every write with the corresponding schemas/*.jq file.

One-Round Rule: A finding that already carries provenance.falsification_attempts from the current session is skipped. Do not falsify falsifications.


Phase 0: Parse Arguments and Initialize

Step 0.1: Parse Arguments

Input sanitization: truncate $ARGUMENTS to 200 characters total, strip backticks and angle brackets.

  • --scope → default all. Valid: all, dimension:<dim> (where <dim> is one of competitive|sizing|trends|customer|tech|financial|regulatory|trend_modeling), finding:<id> (where <id> matches f_[a-z_]+_[0-9]+). Invalid → error and stop.
  • --query-budget → default 6. Integer 1–10. Out of range → clamp and warn.
  • --claim-budget → default 50. Integer 1–500. Out of range → clamp and warn.
  • --mode → default block. One of block (any falsified verdict halts downstream phases) or advisory (all verdicts are annotation only). Invalid → error and stop.

Step 0.2: Find Active Research Session

Scan ./reports/*/state.json for sessions with status in {"active", "complete"}. Pick most recently updated. Extract topic, topic_slug, elicitation.

If no session found, error: "No research session found. Run /sigint:start <topic> first."

Resolve reports_dir from config (REQUIRED — do not hardcode paths):

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.

falsify is a skill published in the GitHub repository zircote-plugins/sigint (20 stars, last pushed 15d ago), licensed MIT. It adds 100 tokens to every session and 4,230 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
