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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds useful content-level disclosure (that watermark/export-quality constraints and live pricing/entitlements come back), but says nothing about the default-workspace behavior implied by a nullable workspaceId, or about any auth/plan gating on the pricing data.

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, front-loaded with the read operation, and every clause carries distinct information. The enumeration is long, but each item names a different data domain rather than padding.

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?

An output schema exists, so the entire second sentence enumerating return values (export quality, plan names, prices, credits, upgrade URL) largely duplicates structured data. That space would have been better spent on the null-workspaceId semantics or on when to prefer this over the save/scan siblings.

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 0% for the single parameter, so the description must carry it — and it only loosely does by saying "the selected workspace's". The schema allows null with default null, which almost certainly means 'use the currently selected workspace', but the description never states that, leaving a real ambiguity for a required-but-nullable field.

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?

Opens with a specific verb+resource ("Read the selected workspace's ...") and enumerates the concrete data domains it returns, which clearly separates it from write-side siblings like workspace_context_save and scan-side ones like workspace_brand_scan. It stops short of naming any sibling, and the second sentence shifts to a different subject (billing/entitlements), making the tool's scope slightly straddled.

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 statement of when to call this versus alternatives, no prerequisites, no exclusions. With workspace_context_save, workspace_brand_scan, workspace_brand_scan_get and workspaces_list all in the sibling set, the agent gets no routing signal for which one to reach for.

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