  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 14 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by legioncodeinc on GitHub. Read the source before you install it.

Installation

Install the Investor Cap Table Stinger AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/legioncodeinc/vibe-coding-tools/tree/main/plugins/business-and-product-tools/skills/investor-cap-table-stinger
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/legioncodeinc/vibe-coding-tools.git /tmp/vibe-coding-tools
mkdir -p .claude/skills
cp -r /tmp/vibe-coding-tools/plugins/business-and-product-tools/skills/investor-cap-table-stinger .claude/skills/investor-cap-table-stinger
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Investor Cap Table Stinger in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Investor Cap Table Stinger on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Investor Cap Table Stinger is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

investor-cap-table Stinger

Start with README.md for the workflow map and detailed references.

Procedural arsenal for investor-cap-table-wasp-drone. Covers the full equity lifecycle for startup founders: cap-table platform selection, SAFE mechanics, priced-round term sheet interpretation, 409A valuations, option pool management, vesting schedules, and Series A data-room preparation.

Critical context from research (2026-05-20):

  • AngelList Stack stopped accepting new customers in August 2026. Do not recommend it for new startups. Platform selection is now Carta vs Pulley as the primary choice, with Cake Equity and Capdesk as international alternatives.
  • 83% of SAFEs issued in 2024 use the post-money structure. YC removed the pre-money SAFE from its website in 2018. Always default to post-money.
  • A signed term sheet invalidates a current 409A. Granting options between a signed term sheet and a new 409A exposes employees to 20% federal penalty taxes. This is the single most dangerous 409A gotcha.

When this stinger applies

Load this stinger when investor-cap-table-wasp-drone is invoked. Primary triggers:

  • "Set up our cap table" / "which cap table platform should we use?"
  • "Carta vs Pulley" / "how do I pick between cap table tools?"
  • "How does a SAFE work?" / "SAFE conversion mechanics" / "post-money vs pre-money SAFE"
  • "What's in a term sheet?" / "explain this term sheet provision" / "liquidation preference"
  • "When do I need a 409A?" / "409A valuation timing" / "Carta 409A"
  • "How big should our option pool be?" / "option pool refresh" / "ESOP dilution"
  • "Vesting schedule" / "cliff vesting" / "double-trigger acceleration"
  • "Data room for Series A" / "due diligence checklist" / "what investors want to see"

Do NOT load for company formation (that is incorporation-startup-stack-stinger), subscription billing mechanics (that is payments-stinger), or legal document drafting (that is legal-docs-stinger).

First action when this stinger is loaded

  1. Read guides/00-principles.md -- the non-negotiables: no spreadsheets, always recommend counsel, post-money SAFE as default, and the jurisdiction scope (US Delaware C-Corps; flag non-US for local counsel).
  2. Identify the founder's stage and specific question.
  3. Navigate to the relevant guide:
    • Platform selection → guides/01-platform-selection.md
    • SAFE mechanics → guides/02-safe-mechanics.md
    • Priced round / term sheet → guides/03-priced-round-mechanics.md
    • 409A valuations → guides/04-409a-valuations.md
    • Option pool → guides/05-option-pool-management.md
    • Vesting schedules → guides/06-vesting-schedules.md
    • Data room → guides/07-data-room-checklist.md

Critical directives

  • Never recommend spreadsheets for cap-table management beyond a single-founder, pre-incorporation scenario. Spreadsheets have no audit trail, no e-signature workflow, no 409A integration, and are rejected by institutional investors at due diligence.
  • Always recommend qualified lawyer review before signing any legal instrument. The Angel interprets financial and cap-table mechanics; it does not provide legal advice.
  • Default to the YC post-money SAFE for US startups unless the user explicitly names a different instrument. Deviating requires specific justification.
  • State dilution impact explicitly any time you discuss issuing shares, options, or SAFEs. Founders systematically underestimate dilution.
  • Flag the jurisdiction boundary. This stinger is calibrated for US Delaware C-Corps. For UK, EU, Australia, or other jurisdictions, flag the gap and recommend local counsel.

Frequently asked questions

What does the Investor Cap Table Stinger AI skill do?

Manage startup cap tables and fundraising paperwork. Use for SAFEs, options, 409A, priced rounds, vesting, or data rooms. Read README.md for the guide map.

Why use Investor Cap Table Stinger on TypingMind?

Because you install it once and use it with any model. Investor Cap Table Stinger is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Investor Cap Table Stinger in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/legioncodeinc/vibe-coding-tools/tree/main/plugins/business-and-product-tools/skills/investor-cap-table-stinger. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Investor Cap Table Stinger?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Investor Cap Table Stinger?

As many as you like. As long as a model supports skills, you can use Investor Cap Table Stinger with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Investor Cap Table Stinger AI skill free?

Yes. It is published on GitHub by legioncodeinc under the AGPL-3.0-or-later license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
