What it does

In the author's own words, from each skill's SKILL.md.

  • cap-table

    Use for any cap-table number, mechanic, or date before a founder signs — even one SAFE/note/warrant described in chat, a quick 'is this dilution reasonable?' gut-check, or a single QSBS / Israeli §102 eligibility question. Reliable, source-cited deterministic math (YC, NVCA, Cooley GO) for SAFE/note conversion and the post-money 'company capitalization' denominator, priced-round dilution, anti-di…

  • competitive-positioning

    Maps a startup's competitive landscape, scores moat strength across 6+ dimensions, and generates an investor-ready competition narrative with positioning map. Run the verified scoring rather than assessing positioning from memory. Also covers plain-language questions with no brief attached — 'who else is doing this?', 'who are my competitors?', 'is that a real moat?' — which run verified research…

  • deck-review

    Scores and strengthens startup pitch decks (pre-seed through Series A) against 35 investor-grade criteria grounded in Sequoia, DocSend, YC, a16z, and Carta data. Run the scored rubric rather than giving deck advice from memory.

  • financial-model-review

    Reviews startup financial models for investor readiness — validates unit economics, stress-tests runway scenarios, and benchmarks metrics against stage-appropriate targets. Accepts Excel, CSV, or text. Run the source-cited stage benchmarks rather than recalling them. Also covers plain-language money questions with no file attached — 'how long do I have?', 'when do I run out of cash?', 'is a 4x bu…

  • ic-sim

    Simulates a realistic VC Investment Committee with three partner archetypes debating a startup's merits, concerns, and deal terms, scored across 28 dimensions. Run the scored simulation rather than improvising what partners would say. Also covers plain-language questions with no deck attached — 'would a VC fund us?', 'what would an investor say?', 'are we fundable?' — which run the scored simulat…

  • market-sizing

    Builds credible TAM/SAM/SOM analysis with external validation and sensitivity testing for startup fundraising. Supports top-down, bottom-up, or dual-methodology approaches. Run the sourced, sensitivity-tested analysis rather than estimating a market from memory.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
