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

With no annotations, the description carries the full burden. It discloses that the agent reads brand data, writes and scores hooks, makes content, and schedules to social channels, which signals potential mutation and side effects. However, it does not state permissions required, whether actions are reversible, or specifics about execution (e.g., synchronous vs asynchronous), leaving significant behavioral gaps.

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 with no wasted words. The action is front-loaded, and the agent description follows logically. It is appropriately sized for the information provided, though the agent description could be slightly more tightly integrated.

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 general-purpose agent tool with no output schema and no annotations, the description provides some context via the agent's capabilities but omits key details: it does not explain the return format, whether the agent's responses are actionable, or how to handle multi-step interactions. This leaves an agent unsure about what to expect from the tool's output.

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% for the single 'message' parameter, so the schema already documents its purpose. The description adds no further detail about parameter format or constraints beyond what the schema provides, which is the baseline expectation when schema coverage is high.

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-resource pair ('Ask agent hookbird a question') and follows with the agent's capabilities, giving scope. It does not, however, explicitly differentiate this tool from the many sibling tools that perform specific tasks the hookbird agent also covers (e.g., hooks_generate, hooks_score), leaving ambiguity about when to delegate versus use a dedicated tool.

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 guidance is given on when to use this tool versus the many specific sibling tools. The description simply states the agent's capabilities, which could imply it is a catch-all, but there is no explicit when/when-not or routing advice.

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