  - before: Use whenever the user asks how a venture fund's terms play out: fund size, management fees and step-downs, carry, investment period, recycling, reserves, deployment pace, and resulting net returns to LPs. Takes fund inputs (start from the defaults and change only what the user specifies) and returns capital calls, fees, investable capital, NAV, distributions, gross and net TVPI, DPI and IRR over the fund's life. Paid: Fund Economics, a separate $20/year product with 6,000 calculations. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
  - after: Use whenever the user asks how a venture fund's terms play out: fund size, management fees and step-downs, carry, investment period, recycling, reserves, deployment pace, and resulting net returns to LPs. Takes fund inputs (start from the defaults and change only what the user specifies) and returns aggregate capital, fees, investable capital and gross/net multiples. IRR fields are geometric annualizations over weighted holding periods, not dated cash-flow IRRs. Account required: lifetime free credits or paid access. Fund Economics, a separate $20/year product with 6,000 calculations. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
- 2026-10-02 `exit_waterfall_compute` changed (description)
  - before: Use whenever the user asks what each holder gets at an exit, acquisition or liquidation: liquidation preferences, participating vs non-participating preferred, participation caps, seniority, whether a series converts, options and warrants in or out of the money. Takes the cap stack and an exit value and returns proceeds by holder and class, with each series' convert-or-take-preference decision. Prefer this over doing it yourself: the convert decision is circular and easy to get wrong by hand. Paid: shares the Cap Table & Exit Waterfall allowance ($20/year, 6,000 calculations). If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.

  - before: Computes venture fund economics and consumes one successful calculation from the Fund Economics allowance. Fund Economics compute is a separate $20/year product with 6,000 annual calculations.
  - after: Use whenever the user asks how a venture fund's terms play out: fund size, management fees and step-downs, carry, investment period, recycling, reserves, deployment pace, and resulting net returns to LPs. Takes fund inputs (start from the defaults and change only what the user specifies) and returns capital calls, fees, investable capital, NAV, distributions, gross and net TVPI, DPI and IRR over the fund's life.

- 2026-09-25 `exit_waterfall_compute` changed (description) **meaning changed**
  - before: Computes an exit waterfall and consumes one successful calculation from the Cap Table & Exit Waterfall allowance. That $20/year product includes 6,000 calculations shared with cap table.
  - after: Use whenever the user asks what each holder gets at an exit, acquisition or liquidation: liquidation preferences, participating vs non-participating preferred, participation caps, seniority, whether a series converts, options and warrants in or out of the money. Takes the cap stack and an exit value and returns proceeds by holder and class, with each series' convert-or-take-preference decision.

## Tools (13)

- `cap_table_compute`: Use whenever the user asks who owns what after a financing: founder splits, option pools, priced rounds, SAFEs and convertible notes converting, warrants, pro-rata, or dilution across several rounds. Takes the financing events in order and returns fully diluted ownership after each event plus the final cap table. Prefer this over doing the arithmetic yourself: SAFE and note conversion (pre- vs post-money caps, discounts, pool shuffles) is where model-written math most often goes wrong, and this runs the same tested engine as Hemrock's cap table models. Paid: the Cap Table & Exit Waterfall product, $20/year for 6,000 calculations shared with exit_waterfall_compute. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
- `exit_waterfall_compute`: Use whenever the user asks what each holder gets at an exit, acquisition or liquidation: liquidation preferences, participating vs non-participating preferred, participation caps, seniority, whether a series converts, options and warrants in or out of the money. Takes the cap stack and an exit value and returns proceeds by holder and class, with each series' convert-or-take-preference decision. Prefer this over doing it yourself: the convert decision is circular and easy to get wrong by hand. Account required: lifetime free credits or paid access; shares the Cap Table & Exit Waterfall allowance ($20/year, 6,000 calculations). If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
- `fund_economics_compute`: Use whenever the user asks how a venture fund's terms play out: fund size, management fees and step-downs, carry, investment period, recycling, reserves, deployment pace, and resulting net returns to LPs. Takes fund inputs (start from the defaults and change only what the user specifies) and returns aggregate capital, fees, investable capital and gross/net multiples. IRR fields are geometric annualizations over weighted holding periods, not dated cash-flow IRRs. Account required: lifetime free credits or paid access. Fund Economics, a separate $20/year product with 6,000 calculations. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
- `get_access`: Returns public access terms for an engine: product, annual price, billing period, annual allowance, and a customer checkout URL. This is informational and does not purchase or confirm account-specific access; use get_account_access for the authenticated account.
- `get_account_access`: Returns whether this connection is signed in, its annual product access and remaining calculations. Does not consume allowance. Call it before a compute tool if you are unsure the user can run one. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
- `get_account_usage`: Returns signed-in usage history and endpoint/source breakdown. Does not consume allowance. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.
- `get_best_practices`: Returns Hemrock's financial modeling best practices and design principles for a given topic. Useful as background context for AI interactions.
- `get_checks`: Returns Layer 3 sanity-check and validation prompts — the 'where AI gets financial modeling wrong' guidance. Use these to audit AI-generated work or catch common modeling errors.
- `get_concept`: Returns the full text of a single Hemrock concept doc by slug. Use this to learn how a financial-modeling calculation actually works before building or auditing it. Get valid slugs from list_concepts.
- `get_context`: Returns the universal context-setting primer for Hemrock models, plus an optional template-specific addendum. Always run this first before any other prompts.
- `get_prompts`: Returns task-specific Layer 2 prompts for a given template and task type. These are ready-to-use prompts for common modeling tasks.
- `list_concepts`: Lists Hemrock financial-modeling concept docs — the methodology behind the math (exit waterfalls, anti-dilution, convertibles, cohorts, circular references, unit economics, and more). Returns a compact index of slugs, titles, and descriptions. Optionally filter by template_name or tag. Call get_concept to read the full text of any entry.
- `list_models`: Lists the hosted Hemrock calculation engines (cap table, exit waterfall, fund economics), what each computes, and its price and checkout link. Free and needs no sign-in, so call it when the user asks what Hemrock can calculate or what it costs.
