Founder Skill

Router skill for startup workflows. Detects task type and routes to appropriate workflow that produces usable artifacts.

When This Skill Activates

You're working on:

  • Validating a product idea or value proposition
  • Calculating market size (TAM/​SAM/​SOM)
  • Analyzing competitive landscape or threats
  • Building or evaluating a pitch deck
  • Preparing for investor meetings
  • Modeling unit economics, projections, or cash flow
  • Planning a product launch
  • Creating board reports or updates

Workflow Selection

Announce which workflow you're using before starting:

TAM/​SAM/​SOM, market opportunitySize Marketreferences/​market-size.mdTables + Marp slide

Dimensions

This skill has multiple configuration dimensions. See compatibility-matrix.md for:

  • Workflow x Stage (Pre-Seed to Growth)
  • Validation Verdict x Next Workflow
  • Pitch Deck x Audience
  • Financial Model Depth x Funding Stage
  • Board Report x Company Health
  • Market Size Approach x Market Type
  • Launch Phase x Traction Level

Use ✓✓ combinations when possible; avoid ✗ combinations.

Usage

  1. Detect which workflow applies based on user's task
  2. Check compatibility matrix for dimension compatibility
  3. Announce: "I'm using the founder skill for [workflow]"
  4. Load the appropriate reference file
  5. Execute the workflow with confirmation gates (see below)
  6. Produce the specified artifact

Confirmation Gates

Multi-step workflows pause at checkpoints to prevent wasted work when intent drifts.

Gate Points:

PhaseGate
After research/​discovery⚠️ CHECKPOINT: "Does this understanding match your intent?"
After approach/​structure⚠️ CHECKPOINT: "Here's my proposed approach. Should I proceed?"
Before final artifact⚠️ CHECKPOINT: "Ready to generate [artifact]. Confirm?"

Skip gates: Say "proceed without confirmation" to run uninterrupted.

In workflows: Each reference file should pause at these points:

### Phase 2: Analysis

[... phase content ...]

⚠️ **CHECKPOINT**: Present findings summary. Ask: "Does this capture the key insights? Any adjustments before I continue?"

Artifact Tooling

After generating markdown artifacts, users can convert them:

ArtifactToolCommand
Slides (Marp)Marp CLInpx @marp-team/​marp-cli slides.md --pptx
Documentsmd-to-pdfnpx md-to-pdf document.md
SpreadsheetsCopy tablesPaste markdown tables into Google Sheets/​Excel

Rules

  • Always ask clarifying questions before generating artifacts
  • Produce complete, usable outputs (not partial drafts)
  • Use Marp format for all slide decks
  • Use markdown tables for spreadsheet data (easy paste)
  • Be brutally honest in evaluations (2% YC acceptance rate mindset)
  • Include confidence levels and key assumptions

Quality Footer (Required for High-Stakes Outputs)

All validation, pitch, and financial outputs MUST end with:

---
| Confidence | X-Y% |
| Key Assumption | [What would change this verdict] |
| Reversibility | Type 2A/​2B/​1 |

Verdict rules:

  • GO verdict requires ≥70% confidence
  • ITERATE requires identifying specific unknowns to resolve
  • KILL must cite specific evidence, not intuition

Common Rationalizations (All Wrong)

ThoughtReality
"The market is huge"TAM without SAM/​SOM is meaningless.
"Nobody's doing this"If nobody's doing it, ask why.
"We just need 1% of the market"That's not a strategy, it's wishful math.
"First mover advantage"First movers usually lose. Execution wins.
"Build it and they will come"Distribution is harder than product.
"We're different"Every founder says this. Prove it with evidence.
