Compute a cap table

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.

TDQS

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond readOnlyHint=true the description discloses the monetization model ($20/yr), that the 6,000-calculation allowance is shared with exit_waterfall_compute, the action_required outcome (not signed in, no purchase, allowance used) and the required response to it ('relay it with its links and offer to retry; never skip silently'). These auth/quota behaviors cannot be inferred from annotations or schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the trigger and the outcome, then supporting rationale, then payment/error handling. Dense but each sentence carries actionable information; only slight risk of over-length for a two-parameter tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description still states the return shape (fully diluted ownership after each event plus the final cap table), the payment/quota context, and the action_required handling, so an agent has everything needed to call and act on the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50%; the description enumerates the event categories (founders, pools, rounds, SAFEs, notes, warrants) which maps to the discriminated event types and reinforces chronological ordering, but says nothing about idempotency_key and adds no field-level syntax beyond what the schema already carries.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource (computes the cap table / fully diluted ownership) and enumerates the exact financing constructs it handles: founder splits, option pools, priced rounds, SAFEs/notes, warrants, pro-rata, dilution. An agent can distinguish it from exit_waterfall_compute and fund_economics_compute without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit when-to-use trigger ('whenever the user asks who owns what after a financing'), an explicit alternative to avoid ('prefer this over doing the arithmetic yourself'), and a reason (SAFE/note conversion math is error-prone). It also names the sibling whose quota it shares.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
