Daily Mission

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

Without annotations, the description carries the burden. It mentions 'deterministically generate' and 'mirroring rotation', hinting at reproducibility and alignment with an external process, but fails to disclose if it's read-only, requires authentication, error handling, or output format.

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?

A single sentence that is moderately concise and front-loaded with the action, but it packs many details making it slightly dense. It could be split for clarity without losing information.

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?

The tool has 3 parameters, no output schema, and no annotations. The description covers the mission types but omits explanation of date, sequence, output structure, or any preconditions, leaving significant gaps for an agent to use it correctly.

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 0% but the description implicitly defines the 'kind' parameter by listing the four mission types, adding context beyond the raw enum. However, the 'date' and 'sequence' parameters are entirely undocumented, leaving ambiguity.

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 clearly states it generates a daily practice mission and lists the four specific types (creator spotlight, lightning quiz, etc.), which provides a strong verb-resource pairing. However, it does not differentiate from sibling tools like practice_coach or phrase_library, so it loses a point.

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 on when to use this tool vs. siblings, no prerequisites or usage context provided. The description only explains what it does, not when it should be selected.

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