Close Cap Table Round

cap_table_close_cap_table_round

Destructive

CloseCapTableRound PERMANENTLY closes the round: runs the calc engine, persists the SAFE conversions + ownership snapshots, and flips the round to CLOSED. This is the action for "close the round", "make it permanent", or "finalize the round" — it CANNOT be undone and writes the cap-table of record, so confirm with the user first. To only estimate the outcome without closing, use PreviewCloseCapTableRound.

A4.2/5.0

Behavior5/5

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

Goes well beyond the destructiveHint annotation by explaining exactly what is persisted (SAFE conversions and ownership snapshots), that the round is flipped to CLOSED, that the action writes the cap-table of record, and that it cannot be undone. The user-confirmation requirement is also called out.

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

Conciseness5/5

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

Three sentences, front-loaded with the irreversible action, followed by alternative-tool guidance. Every sentence earns its place with no repetition or filler.

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

Completeness3/5

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

The behavioral and safety context is complete, and the output schema covers return values. However, for an 8-parameter mutation with only 25% schema description coverage, the description leaves the optional financial parameters unexplained, creating a real gap for correct invocation.

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

Parameters1/5

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

Schema description coverage is only 25%, and the description does not explain any of the 8 parameters — including newMoneyRaise, optionPoolBasis, preMoneyValuation, and targetOptionPoolPct. With low schema coverage, the description needed to compensate but added no parameter meaning.

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 and resource: PERMANENTLY closes the round, runs the calc engine, persists SAFE conversions and ownership snapshots, and flips the round to CLOSED. This clearly distinguishes it from preview or update siblings.

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?

Explicitly names the trigger phrases ('close the round', 'make it permanent', 'finalize the round') and the alternative tool for estimation only: PreviewCloseCapTableRound. It also instructs the agent to confirm with the user first.

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