tracks_patch

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

With no annotations, the description carries full burden. It only says 'Partial update' but does not disclose idempotency, merge behavior (e.g., whether releases replace or append), error conditions, or required authentication.

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 at 4 words, earning its place by being direct. However, it could benefit from a bit more structure (e.g., listing key parameters or behavior) without losing 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 4 required parameters, no output schema, and no surrounding context, the description is insufficient. An AI agent lacks guidance on what 'track state' means, how releases work, or that this operates within Google Play Console. A sibling tool list hints at domain but does not compensate.

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 75% for parameter descriptions. The description adds no extra meaning beyond the schema for the described params, and for 'releases' it provides no guidance on structure or semantics (e.g., what constitutes a valid release). The word 'partial' hints at selective field updates but is not parameter-specific.

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 performs a 'partial update' of 'track state', using a specific verb and resource. It distinguishes itself from full update (tracks_update) and create (tracks_create) via the word 'partial'.

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 usage guidance is provided. The description does not explain when to use tracks_patch versus tracks_update or tracks_create, nor does it mention prerequisites like having an active edit.

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