agent_chat_helper

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

Annotations are absent, placing full burden on the description. The description only says 'Multi-purpose helper tool for various operations,' which discloses no behavioral traits (e.g., side effects, auth needs, rate limits). The action list provides some context but the description itself is insufficient.

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?

The description is very concise (one sentence), but conciseness comes at the cost of informativeness. It is front-loaded but lacks substance. It meets minimal structure requirements.

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?

Given the tool's complexity (4 parameters, 6 actions) and absence of output schema, the description is incomplete. It does not explain what each action returns, how to use them, or any constraints. More detail is needed for an agent to use it effectively.

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 coverage is 100% with parameter descriptions. The tool description does not add meaning beyond the schema, but with high coverage, baseline 3 is appropriate. The description could clarify parameter relationships but does not.

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?

The description is vague: 'Multi-purpose helper tool for various operations.' It does not specify the core function or distinguish from sibling tools like agent_chat_register or agent_chat_send. The action enum hints at capabilities, but the description itself lacks specificity.

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 provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or when to choose another tool. The description is generic and does not help the agent decide to invoke this tool.

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