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

Annotations already declare this is a non-destructive, non-open-world write-ish operation. The description adds genuinely new behavioral context the annotations don't carry: a paid/Founder subscription gate and a mandatory API key with a URL for obtaining it. It still does not describe cost, latency, or repeat-call behavior.

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

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

Two sentences, front-loaded with the deliverable list, with the prerequisite and API-key note following. Dense but every element carries information; the bracketed API-key sentence is slightly redundant with the preceding prerequisite sentence.

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

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

For a 7-parameter generator with no output schema and no parameter descriptions, the description covers the access and output-shape story well but leaves the entire input contract undocumented. An agent knows it can call the tool and what it needs to pay, but not what values the 7 inputs should take (e.g., goal strings, audience format).

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

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

Schema description coverage is 0% across 7 parameters, so the description carries the full burden of explaining inputs — and it explains none of them. businessName, industry, targetAudience, goals, platforms, voiceTone, and description are all left for the agent to infer from their names alone.

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

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

States a specific verb (generate) and resource (social media strategy + content kit) and enumerates the concrete deliverables: posts, captions, calendar, analytics framework. This clearly separates it from siblings like generate_brand_kit and generate_legal_docs without needing to read the schemas.

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

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

The description states an access prerequisite (Founder sub or SOCIAL_MEDIA_KIT purchase, plus a namemy.app API key) which is useful gating, but never says when to choose this tool over sibling generators or what contexts call for it. Usage is only implied by the deliverable list.

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