What it does

Dd Verification is an agent skill from Abilityai/trinity. Verify claims in pitch decks and founder statements using multiple independent sources. Use when analyzing any claim about market size, traction, team background, or competitive positioning.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Fundraising and pitch decks and Fact-checking and source verification. It works with Model Context Protocol. The repository describes itself as: Self-hosted AI Agents Platform supporting Claude Code, Codex, Gemini agents. Apache 2.0. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 4357627. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dd Verification loads about 635 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~52
When it runs · the whole SKILL.md, loaded when a task matches: ~635

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Verify claims in pitch decks and founder statements using multiple independent sources. Use when analyzing any claim about market size, traction, team background, or competitive positioning.

Claim Verification Methodology

When analyzing claims from pitch decks, founder statements, or company materials, follow this rigorous verification process.

Verification Levels

Assign one of these confidence levels to every claim:

Level	Definition	Requirements
VERIFIED	Confirmed via 2+ independent sources	Multiple credible sources agree
PARTIALLY VERIFIED	Some evidence supports, gaps remain	One credible source + logical consistency
UNVERIFIED	Cannot confirm with available data	No independent sources found
CONTRADICTED	Evidence conflicts with claim	Sources disagree with stated claim

Verification Process

1. Identify the Claim

Extract the specific, testable assertion:

❌ "We're growing fast" (vague)
✅ "We grew 300% YoY in 2024" (specific, testable)

2. Find Independent Sources

Never rely solely on company-provided materials. Seek:

Public filings (SEC, state records)
Third-party data providers (Crunchbase, PitchBook, LinkedIn)
Press coverage (with dates)
Customer reviews and testimonials
Industry reports from analysts

3. Cross-Reference

Compare across sources:

Do numbers align within reasonable variance (±10%)?
Are timelines consistent?
Do different sources tell the same story?

4. Document Everything

For each verified claim, record:

json

{
  "claim": "The specific claim text",
  "confidence": "VERIFIED | PARTIALLY VERIFIED | UNVERIFIED | CONTRADICTED",
  "sources": [
    {"name": "Source name", "url": "URL if available", "date": "YYYY-MM-DD"}
  ],
  "notes": "Any caveats or context"
}

Red Flags

Watch for these warning signs:

Round numbers without context ("$10M ARR exactly")
Claims that can't be independently verified
Metrics that don't match industry standards
Vague timeframes ("recently", "soon")
Comparisons without clear methodology

Output Format

Include a verification summary in your analysis:

json

{
  "verification_summary": {
    "total_claims_analyzed": 15,
    "verified": 8,
    "partially_verified": 4,
    "unverified": 2,
    "contradicted": 1
  },
  "key_concerns": [
    "Market size claim contradicted by industry reports",
    "Founder employment dates don't match LinkedIn"
  ]
}
