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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, and the description usefully adds an ordering dependency and a human-confirmation requirement before the write. It does not disclose whether a repeat call overwrites a previous onboarding record, whether the write is idempotent, or what a call without prior user consent does.

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 short clauses, front-loaded with the prerequisite last, and nothing is padded or redundant. The brevity is under-specification rather than economy for a six-parameter mutation tool.

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?

A write tool with six params, no output schema and no parameter documentation needs the description to carry the meaning of action, retention and client, and it does not. An agent can infer the sequence but not what it is committing the workspace to when it calls this.

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?

Six parameters with 0% schema description coverage and five of them required, yet the description mentions no parameter at all. The enums for action (confirm/skip), retention (automatic/manual) and client carry the real semantics and are left entirely unexplained, so an agent must guess what instruction_version=1 or retention=automatic commits to.

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?

"Record memory setup" names an action and a domain, and the tool reads as a state-persisting update for onboarding. But it never states that it records the user's confirm/skip decision plus retention mode, nor does it distinguish itself from the memory-related siblings like brand_memory_write or workspace_settings_save.

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 a concrete prerequisite ("workspace_get onboarding first") and a gate ("after user confirmation"), which is more than most siblings offer. It stops short of stating when not to use it, e.g. what to do if the user declines, or that the skip action is the path when no memory should be created.

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