Preview Close Cap Table Round

cap_table_preview_close_cap_table_round

Read-only

PreviewCloseCapTableRound runs the SAME engine as CloseCapTableRound but does NOT persist or close anything — no status change, no snapshot writes. This is the action for "preview", "what-if", or "estimate the close"; it never finalizes the round. To actually close/finalize, use CloseCapTableRound.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds concrete behavioral context beyond that: same engine as the close, no status change, no snapshot writes, nothing persisted. It stops short of describing output shape or side-effect nuances, so not a 5.

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 tight sentences, front-loaded with the core distinction (runs the same engine, does not persist) before the usage guidance and the alternative. No redundant restatement of the name or title.

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

Completeness4/5

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

With an output schema present, return values need not be explained, and the description fully covers the persist/no-persist distinction that matters most. The one gap is the undocumented simulation inputs, which a preview tool ideally would characterize given the low schema coverage.

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

Parameters2/5

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

Schema description coverage is only 33% and 4 of 6 parameters (newMoneyRaise, optionPoolBasis, preMoneyValuation, targetOptionPoolPct) are undocumented in the schema. The description adds no parameter semantics at all, so it fails to compensate for the coverage gap on a what-if simulation whose inputs materially change the result.

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 (preview closing a cap table round) and explicitly distinguishes itself from its sibling by naming CloseCapTableRound. An agent can tell the two apart without opening either 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?

Gives explicit trigger words ('preview', 'what-if', 'estimate the close') and the exclusion ('never finalizes'), plus names the alternative action (CloseCapTableRound) for actually finalizing. When-to-use and the alternative are both stated outright.

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