dudu

dudu

Built for the Lyra Codex hackathon. Instead of just research and gather data, it adds quantitative value on top of it with grounded ICP test and real customer interview flow.

A layered VC due-diligence plugin. Layer 1 (dudu:background-check) gives you the cheap public-source bundle every VC could produce in an afternoon. Layer 2 (dudu:pmf-signal) is the unique deliverable: every founder/company claim verified against a grounded N=15–200 persona simulation, cross-artifact triangulation, and bounded external evidence — emitted as a falsifiable claim ledger × verdict matrix.

Layered architecture

┌──────────────────────────── Layer 1: BACKGROUND CHECK ─────────────────────────┐
│ Cheap. Public sources. Parallel-safe. Produces the L1 sentinel and the         │
│ context bundle that Layer 2 verifies against.                                  │
│                                                                                │
│ dudu:background-check                                                          │
│   ├─ dudu:founder-check                                                        │
│   ├─ dudu:market-context                                                       │

│ Output: deals/<slug>/background.md  (sentinel) + per-skill artifacts.          │
│ NO personas — that namespace is owned by Layer 2.                              │
└────────────────────────────────────────────────────────────────────────────────┘
                                     │
                                     ▼
┌──────────────────────────── Layer 2: PMF SIGNAL ───────────────────────────────┐
│ Expensive. Simulation + cross-artifact + external. The unique value.           │
│                                                                                │

│ Output: pmf-signal.md (claim ledger × verdict), outreach.md (warm-path),       │
│         personas/*.yaml (the simulation), customer-discovery-prep.md           │
│         (legacy-shape convenience artifact, Stage 5 side effect).              │
└────────────────────────────────────────────────────────────────────────────────┘
                                     │
                                     ▼
┌──────────────────────── Standalone: CUSTOMER DEBRIEF ──────────────────────────┐
│ Runs whenever real interview transcripts exist under deals/<slug>/inputs/.     │
│ No orchestrator coupling.                                                      │

For backward compatibility, the deprecated dudu:diligence wrapper still runs the full chain end-to-end. It will be removed in a future release.

Install for Codex

Clone the repo and symlink the skills directory:

git clone https://github.com/Ying-Kai-Liao/dudu.git ~/.codex/dudu
mkdir -p ~/.agents/skills
ln -s ~/.codex/dudu/skills ~/.agents/skills/dudu

Restart Codex to discover the skills. Full Codex install guide (Windows junction variant, troubleshooting, updating) is in .codex/INSTALL.md.

Demo

test/ledgerloop/ contains a complete dudu run against a real Cape Town company (LedgerLoop, founder Dylan Martens), produced from a Codex session under the legacy (pre-split) layout.

What's in there:

• founder-dylan-martens.md — public-web + LinkedIn dossier
• personas/ — context bundle + 3 personas + 6 self-play conversation rounds (legacy market-problem Phase 2 output; under the layered architecture this namespace is now owned by dudu:pmf-signal)
• market-problem.md — cross-round synthesis (legacy filename; the new equivalent is market-context.md)
• competitive-landscape.md — direct/indirect competitors + incumbent threat verdict + moat analysis
• market-sizing.md — bottom-up TAM, anchored on a defined ICP and reachable population
• customer-discovery-prep.md — target list, outreach templates, interview script
• MEMO.md — final stitched investment memo with a Pass verdict and conditional path to Watch
• report.html — single-file rendered version, openable in any browser, safe to share by email
• manifest.json — legacy schema with market-problem and customer-discovery-* keys

The renderer tolerates both legacy and new layouts; legacy demo deals continue to work unchanged.
