verify

verify is a command for Claude Code from synaptiai/synapti-marketplace. It costs 20 tokens per session (1,654 once invoked), scanned A, original, Apache-2.0.

A command for checking factual claims in written content through research and reporting the strength of the supporting evidence.

In plain words
What is it for?
It helps verify a supplied URL, file, or text, research selected claims, compare sources, assess source reliability, and report verification results.
Why use it?
It helps find unsupported or conflicting assertions before content is published, while separating claim extraction from verification.

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

verify 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.

Verify Claims

Verify factual claims in content using deep research methodology. Can be run standalone or after NCI analysis.

Context Isolation: This command uses the claim-verifier agent which auto-loads both the conducting-deep-research and nci-manipulation-analysis skills. Verification happens in a forked context, allowing multiple claims to be researched without polluting the main conversation.

Usage

/decipon:verify <URL or text content>
/decipon:verify --claims "claim1" "claim2" "claim3"

Arguments

  • $ARGUMENTS: Content to analyze OR specific claims to verify
    • Content: URL, file path, or text
    • --claims: Verify specific claims directly

Purpose

Fact-check key claims using deep research:

  • Extract factual assertions from content
  • Research each claim using multiple sources
  • Score source reliability (1-100 confidence)
  • Track contradictions and agreements
  • Report verification status with evidence

Workflow

  1. Extract Claims (if content provided)

    • Identify factual assertions
    • Prioritize by impact (Critical/High/Medium/Low)
    • Focus on verifiable claims (not opinions)
  2. Research Each Claim

    • Apply deep research methodology
    • Search for supporting/contradicting evidence
    • Evaluate source quality
    • Track agreements and contradictions
  3. Evaluate Sources

    • Score confidence (1-100)
    • Note source type and potential bias
    • Check for corroboration
  4. Generate Report

    • Verification status per claim
    • Source citations with confidence
    • Overall credibility assessment

Verification Statuses

Status Meaning
VERIFIED 2+ high-confidence sources support claim
PARTIALLY VERIFIED Core claim true but with caveats
UNVERIFIED Cannot find supporting evidence
CONTRADICTED High-confidence sources refute claim

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.
