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

No annotations provided, so description carries full behavioral burden. It mentions 'clear_history' and 'clear_cache' without warning these are destructive/irreversible operations. The '[PRO]' prefix is unexplained, and there's no indication of performance implications (e.g., 'full sync' vs 'snapshot' costs) or return value structures.

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?

While brief, the structure is poor: an unexplained '[PRO]' tag followed by a colon-separated list that reads like configuration rather than documentation. The density obfuscates that this is a multi-mode tool with both read and destructive write operations.

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 tool supporting 9 distinct operational modes (some destructive, some read-only, some viewport-related), the description lacks critical context: no output format descriptions, no permission requirements for [PRO] or destructive actions, no explanation of 'Workspace' scope in the context of sibling tools like 'manage_scripts'. High schema coverage compensates for parameters but not for behavioral completeness.

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 100%, establishing baseline 3. The main description provides only a terse list matching the enum values, while the schema's action parameter descriptions actually carry the semantic weight (explaining 'sync' fetches hierarchy, 'viewport' gets camera position, etc.). The description adds no syntax guidance 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 identifies the resource (Workspace state) and lists specific operations (sync, snapshot, changes, etc.), but uses noun phrases rather than clear action verbs. It fails to differentiate from siblings like 'manage_sync' or 'manage_scripts' which overlap conceptually with some enum values.

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 when-to-use guidance is provided. Given siblings like 'manage_sync', 'query_instances', and 'system_info', the description should clarify when to prefer this tool's 'sync' or 'snapshot' actions over those alternatives, but provides no decision criteria.

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