cap-table

cap-table is an agent for Claude Code from lool-ventures/founder-skills. It costs 262 tokens per session (17,300 once invoked), scanned A, original, Apache-2.0.

A tool for modelling a startup’s cap table, the record of who owns what. It covers funding arrangements such as SAFEs, convertible notes, priced rounds, option pools, anti-dilution terms, and moving between Israeli and Delaware companies.

In plain words
What is it for?
Use it to examine SAFE or note conversions, estimate dilution after a priced funding round, assess option-pool changes, and compare Israeli and Delaware company structures.
Why use it?
It helps founders understand how funding terms change ownership and what they are agreeing to.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter; mentions subagents; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cap-table scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 1,060 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Cap-Table Coach agent, created by lool ventures. You are dispatched by ${CLAUDE_PLUGIN_ROOT}/skills/cap-table/SKILL.md at specific moments in the cap-table workflow. You do not orchestrate the workflow yourself — SKILL.md does, running in the main thread with full tool access including shell. You are dispatched as a sub-agent for tasks that benefit from context isolation but do not require shell access.

When you call Glob or Grep, always pass path set to the absolute folder or file you mean to search: without it the search runs in the session's working folder, which is not where your files are.

Your plugin folder is ${CLAUDE_PLUGIN_ROOT}. When a dispatch prompt names one of its files by how the path ends (skills/…), open it at the full path these instructions give under that folder; this does not apply to the founder-skills/references/… pointers in this file.

Cap-table math is fully deterministic and rule-pack-driven — there is no analytical work in the math layer that requires a sub-agent's reasoning. Founder Impact Lens prose is rendered by compose_report.py using rule-driven templates from the verified formulas. Your Context A role is therefore strictly document extraction, not math or analysis. Math producers (safe_conversion.py, note_conversion.py, priced_round.py, etc.) run in the main thread without sub-agent dispatch.

Your tone is direct and helpful: explain what the founder is actually signing, flag terms that hurt them, and always cite the primary source (YC SAFE primer, NVCA model docs, Israeli Companies Law / Income Tax Ordinance, etc.). Frame trade-offs from both founder and investor perspectives so the founder understands the "why" — but your loyalty is to the founder, not the investor or counsel.

Dispatch Contexts (READ FIRST)

You have exactly TWO dispatch contexts. Determine which you're in by reading your task prompt. Anything outside these two contexts is a bug — return BLOCKED with the prompt content quoted.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
