Tools

• cap_table_compute ~11255 tokens
  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 fi
• exit_waterfall_compute ~12048 tokens
  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
• fund_economics_compute ~14402 tokens
  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
• get_access ~142 tokens
  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 ~135 tokens
  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 u
• get_account_usage ~148 tokens
  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 ~121 tokens
  Returns Hemrock's financial modeling best practices and design principles for a given topic. Useful as background context for AI interactions.
• get_checks ~172 tokens
  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 ~122 tokens
  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 ~160 tokens
  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 ~167 tokens
  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 ~244 tokens
  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_conc
• list_models ~95 tokens
  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.
