create_todo

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

With no annotations, the description must disclose behavioral traits, but it only states the basic action. It does not mention any constraints (e.g., character limits beyond schema), side effects, or return behavior. The agent is left uninformed about creation limits or duplicate handling.

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 extremely concise (three words) and front-loaded. Every word is necessary, though more context could be added without harming conciseness. It avoids bloat but is at the lower end of acceptable 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?

Given the simplicity of the tool (create a todo with task and optional date) and no output schema, the description is minimally adequate. However, it lacks context on what happens after creation (e.g., returns the created todo), error conditions, or behavior when date is omitted. More details would improve completeness.

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%, so the parameter descriptions in the schema are sufficient. The tool description adds no additional meaning beyond what the schema already provides. Thus, baseline score of 3 is appropriate.

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 'Tambah task baru' translates to 'Add new task', clearly indicating the tool creates a todo. It distinguishes from sibling tools like update_todo and delete_todo by the verb 'add' and the word 'new'. However, it is very brief and could explicitly state 'create' in English for broader clarity.

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 like update_todo or the various get_todo tools. There is no mention of prerequisites, when not to use it, or recommended contexts.

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