Idempotent

Generate ready-to-use marketing and business content for an idea: blog posts, social media, ad copy, press releases, elevator pitches and 12 more types. Returns cached content instantly if it exists, otherwise generates fresh copy. Spends credits only when generating new content. Not read-only; pass an ideaId you own and a contentType.

A4.7/5.0

Behavior5/5

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

Beyond the annotations, the description discloses caching behavior, credit spending, and ownership requirement. It aligns with idempotentHint (cached content) and readOnlyHint=false, adding valuable operational details without contradicting any annotation.

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?

Four tightly packed sentences, each contributing unique information: purpose, caching, cost, and usage requirement. No filler or repetition of schema details, and the primary action is stated first.

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?

For a 3-parameter tool with full schema coverage, an output schema, and rich annotations, the description covers purpose, behavior, cost, and prerequisites. It gives the agent everything it needs to decide to invoke and execute correctly, and the content type list in the schema covers the remaining specifics.

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

Parameters4/5

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

Schema coverage is 100%, so each parameter is already documented. The description adds the crucial constraint that ideaId must be owned, and reinforces the required contentType. This goes beyond the schema's basic 'The idea ID', providing meaningful usage context.

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?

The description opens with a clear verb-resource pairing ('Generate ready-to-use marketing and business content') and enumerates specific content types, distinguishing it from the get_* read tools. While generate_b2b_pitch is a possible sibling, the description's scope is broader and unambiguous.

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

Usage Guidelines4/5

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

The description gives clear context for use (for an idea, with an owned ideaId and a contentType) and notes it's not read-only, but does not explicitly name alternatives or exclusions. The contextual info is enough to know when to reach for this tool, though it stops short of comparing against specific siblings like generate_b2b_pitch.

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