Measured tools (13)

• get_context read-only

  Returns the universal context-setting primer for Hemrock models, plus an optional template-specific addendum. Always run this first before any other prompts.

  Parameters:

  • template_name — string — Optional. If provided, appends a template-specific primer to the universal context.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_prompts read-only

  Returns task-specific Layer 2 prompts for a given template and task type. These are ready-to-use prompts for common modeling tasks.

  Parameters:

  • template_name (required) — string — The Hemrock template being used.
  • task_type — string — Optional task type filter.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_checks read-only

  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.

  Parameters:

  • template_name (required) — string — The template to get checks for. Use "all" for universal checks only.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_best_practices read-only

  Returns Hemrock's financial modeling best practices and design principles for a given topic. Useful as background context for AI interactions.

  Parameters:

  • topic — string — Optional topic filter. Returns all best practices if omitted.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• list_concepts read-only

  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.

  Parameters:

  • tag — string — Optional. Filter to concepts whose tags contain this string (e.g. "cap tables").
  • template_name — string — Optional. Filter to concepts relevant to a specific Hemrock template.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_concept read-only

  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.

  Parameters:

  • slug (required) — string — The concept slug, from list_concepts (e.g. "waterfall", "anti-dilution").

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• list_models read-only

  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.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• get_access read-only

  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.

  Parameters:

  • model (required) — string — Model key to check access for.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• get_account_access read-only

  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.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• get_account_usage read-only

  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.

  Parameters:

  • to — string — Optional UTC end date (YYYY-MM-DD).
  • from — string — Optional UTC start date (YYYY-MM-DD).

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• cap_table_compute read-only

  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.

  Parameters:

  • events (required) — array
  • idempotency_key — string — Optional retry key; reuse only with identical input.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• exit_waterfall_compute read-only

  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.

  Parameters:

  • exitValuation (required) — number
  • model (required) — object
  • idempotency_key — string — Optional retry key; reuse only with identical input.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• fund_economics_compute read-only

  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 lifetime capital, fees, investable capital and gross/net multiples (result), plus the fund over time by default (detail): capital calls, fees, investments, distributions and NAV by year, DPI/RVPI/TVPI by year, the LP J-curve, IRRs solved from those dated cash flows, and financial statements. Pass granularity "quarter" for quarters or "none" for totals only. Optional features apply when their block is sent: preferred return, catch-up and tiered carry (features.waterfall), NAV/AUM/step-down fee bases (features.fees), LP classes, cap-table portfolio construction, follow-on timing, and a management company budget. result.grossIRR and result.netIRR are geometric annualizations over weighted holding periods; quote detail.irr when the user asks for an IRR from cash flows. When the user wants the Excel model, pass format "xlsx_url" (and fundName to name the file): the response adds workbook.url, a download link to the live workbook that lasts 24 hours, with every number a formula back to the inputs. Give the user that link. 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.

  Parameters:

  • inputs (required) — object
  • format — string
  • features — object
  • fundName — string
  • granularity — string
  • firstCloseDate — string
  • idempotency_key — string — Optional retry key; reuse only with identical input.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes
