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

Beyond the annotations, the description discloses important mutation semantics: omitted fields keep their saved value or default, handle collisions are refused, and a Last Price credential with routing write scope is required. It also explains the claimed-workspace prerequisite and the 403 behavior for sandbox keys from self-registration.

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 front-loaded with the core action and then adds only material operational constraints: partial-update behavior, handle collision refusal, credential scope, and claimed-workspace requirement. Every sentence earns its place.

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?

This is a multi-parameter, destructive configuration tool with no output schema, but the description covers the critical context an agent needs: auth scope, workspace-claim prerequisites, partial-update behavior, defaults, and handle uniqueness. Nothing essential appears to be missing before invocation.

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?

The schema already documents all seven parameters at 100% coverage, so the baseline is 3. The description adds useful cross-parameter semantics by explaining that omitted fields retain saved/default values and that handle uniqueness is enforced across workspaces.

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: turning offers and counter-offers on/off and setting the negotiation schedule for the workspace. It is clearly a configuration setter, but it does not explicitly name or differentiate itself from siblings such as get_offer_settings, make_offer, or preview_offer.

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?

The description gives clear context for use: configuring workspace offer enablement and negotiation behavior. It does not state when to use alternatives like get_offer_settings for reading current values or preview_offer for testing offers, so it lacks explicit exclusions.

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