Update workspace

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

Annotations already cover the safety profile (idempotent, non-destructive, not read-only), and the description adds genuinely new behavior: all-or-nothing validation ('nothing is written if any field is invalid') and that pausing retains history. It stops short of describing the response payload, but the mutation semantics are well disclosed.

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?

Three sentences, no waste: capability first, then the write-safety rule, then the sibling-routing guidance. Every clause carries information an agent needs before calling.

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?

For a 4-param, fully documented mutation tool this is effectively complete, covering scope, atomicity, and alternatives. The only unaddressed element is what a successful update returns, a minor gap given no output schema exists.

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 baseline is 3, but the description adds the partial-update contract ('send only the fields to change') that governs how all four parameters interact, which the per-field schema text does not state as a whole.

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 uses a specific verb and resource and enumerates exactly what can change: rename, set/clear product_url, pause/resume monitors. It distinguishes itself from delete_workspace and update_competitor by name, so an agent can route without opening a schema.

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?

It gives explicit when-to-use guidance ('prefer it over delete_workspace' for pausing) and names the alternative for the narrower case ('To pause one competitor, use update_competitor'). Both the selection condition and the exclusion are stated outright.

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