What it does

Dd Sourcing is an agent skill from Abilityai/trinity. Document sources properly for due diligence reports. Use when citing any external data, ensuring full traceability and auditability of findings.

Its SKILL.md is about 660 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. 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.

When your agent uses it

Citing any external data
Ensuring full traceability and auditability of findings

Example prompts

“/dd-sourcing”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Note the discrepancy explicitly
Prefer higher-tier sources
Prefer more recent sources
Document both versions with reasoning for which to trust

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
Hosts in commands or code, which the agent is likely to contact:
- crunchbase.com
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 Sourcing loads about 664 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 232 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~39
When it runs · the whole SKILL.md, loaded when a task matches: ~664

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.

name: dd-sourcing
description: Document sources properly for due diligence reports. Use when citing any external data, ensuring full traceability and auditability of findings.

Source Documentation Standards

All due diligence findings must be traceable to their sources. This enables audit trails, follow-up verification, and legal defensibility.

Source Quality Tiers

Tier 1: Primary Sources (Highest Credibility)

SEC filings (10-K, 10-Q, S-1)
Court documents and legal filings
Government databases (USPTO, state registrations)
Company's own audited financials
Direct customer/reference interviews

Tier 2: Secondary Sources (High Credibility)

Established data providers (Crunchbase, PitchBook, CB Insights)
Major news outlets (WSJ, Bloomberg, TechCrunch)
Industry analyst reports (Gartner, Forrester)
LinkedIn profiles (for employment verification)
Academic research and papers

Tier 3: Tertiary Sources (Use with Caution)

Social media posts
Blog articles
Glassdoor reviews
Wikipedia (only as starting point)
Forum discussions

Citation Format

Every fact must include a source citation:

json

{
  "source": {
    "name": "Full source name",
    "type": "SEC_FILING | NEWS | DATA_PROVIDER | INTERVIEW | GOVERNMENT | OTHER",
    "url": "https://... (if available)",
    "access_date": "2024-01-15",
    "publication_date": "2024-01-10",
    "tier": 1,
    "excerpt": "Relevant quote or data point"
  }
}

Best Practices

DO:

Capture URLs at time of access (pages change/disappear)
Note the access date for all web sources
Quote relevant passages, don't just link
Use multiple sources for critical claims
Prefer recent sources over older ones

DON'T:

Cite a source you haven't actually reviewed
Use company press releases as independent verification
Rely on a single source for material claims
Cite sources behind paywalls without noting limitation
Mix up "stated by company" vs "independently verified"

Source Tracking in Output

Include a sources section in every analysis:

json

{
  "sources_used": [
    {
      "id": "S1",
      "name": "Crunchbase - Acme Corp Profile",
      "url": "https://crunchbase.com/...",
      "access_date": "2024-01-15",
      "tier": 2,
      "used_for": ["funding_history", "employee_count"]
    }
  ],
  "source_statistics": {
    "tier_1": 3,
    "tier_2": 8,
    "tier_3": 2,
    "total": 13
  }
}

Handling Source Conflicts

When sources disagree:

Note the discrepancy explicitly
Prefer higher-tier sources
Prefer more recent sources
Document both versions with reasoning for which to trust
