update_workspace

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

No annotations provided, so description carries full burden. It discloses that changes are cosmetic and do not affect billing, access, or API keys. Could mention validation or failure behavior, but the key behavioral trait is well described.

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: first states purpose, second clarifies side effects and constraint. No wasted words, front-loaded with core action.

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 output schema exists, no need to explain return values. Description covers purpose, constraints, and side effects. Complete for a simple update tool.

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 75%. Description adds the constraint that at least one of name or display_color must be provided, which is not in schema. Also clarifies the cosmetic nature, adding meaning beyond the schema.

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 'Rename or recolor a workspace', specifying the verb and resource. It distinguishes from sibling tools like archive_workspace or create_workspace by focusing on cosmetic updates.

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?

Explicitly says 'Cosmetic only — does not affect billing, access, or API keys', guiding when to use (cosmetic changes) and when not. Also states the constraint that at least one of name or display_color must be provided.

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