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

Annotations already declare readOnlyHint=false, openWorldHint=true and destructiveHint=false, so the write/side-effect profile is covered structurally. The description adds only the platform type identifier; it says nothing about server-side resolution of free-text skills/titles/companies, credit consumption, or failure modes, which is notable for an open-world creation tool.

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?

One sentence with zero filler and the key discriminator front-loaded. It is efficient, though for a nine-parameter creation tool the terseness shades into under-specification rather than pure conciseness.

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 nine-parameter, open-world creation tool sitting among several near-identical G2/native audience creators, the description does not say how the tool differs from siblings or what the created artifact is (an audience draft vs. a live, actuated audience). With no output schema, the agent gets no help on what comes back.

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 100%, so every parameter already carries documentation, including the 'ask the user, do not default' rule on `buying_stages`. The description adds no additional semantics, so baseline 3 applies.

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 and resource ('Create a G2 Intent - LinkedIn Native (Dynamic) audience') and pins the platform discriminator with `customAudienceType=DYNAMIC_G2`. That distinguishes it from the non-native G2 intent siblings, though it does not explicitly name `create_g2_intent_dynamic_audience` or `create_g2_intent_static_audience` as the alternatives.

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?

No statement of when to use this versus the two sibling G2 intent tools or the other native-audience creators. The agent has to infer from the name that 'LinkedIn Native' means a LinkedIn-side dynamic audience rather than a platform-side one.

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