pitch_build

Build track: pitch a brand-new app or business. Posted to the Suggestion Council; Sun approves -> build. New businesses show 'In the making', may take paid pre-orders, and can be offered for sale only after 30 days of paying customers.

A3.7/5.0

Behavior4/5

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

With no annotations, the description carries the burden and does well: it discloses the approval gate (Sun approves -> build), the visible state ('In the making'), pre-order capability, and the 30-day paying-customer restriction on sale. It omits what happens on rejection and whether a pitch can be edited or withdrawn, which keeps it short of a 5.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.

Conciseness4/5

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

Two sentences, front-loaded with the purpose and track, then the lifecycle consequences. Every clause (council posting, approval, pre-orders, 30-day rule) carries actionable meaning; only minor tightening would be possible.

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?

For an 8-parameter mutation with a nested spec object and no output schema, the description supplies the workflow and downstream consequences an agent needs to decide and act. Gaps remain around failure/rejection handling and the immediate return, but the core decision context is present.

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 100%, so the schema already documents all eight parameters including the spec/spec_md alternative and the price_sol semantics. The description adds no parameter-level detail beyond loosely implying pre-order pricing, so baseline 3 applies.

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

Purpose4/5

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

The description states a specific verb+resource ("pitch a brand-new app or business") and names its track ("Build track"), which separates it from generic suggestion posting. It does not explicitly contrast with siblings like council_suggest or propose_listing, but the 'brand-new app or business' scope makes the target object distinguishable.

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

Usage Guidelines3/5

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

Usage is implied by the 'brand-new' scope and the approval path, but the description never says when NOT to use it (e.g., for listing an existing product, use propose_listing) or names an alternative tool. An agent must infer routing from sibling names alone.

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