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

No annotations provided, so description carries full burden. Mentions 'read/write' implying mutation, but fails to disclose destructive potential of write_file, safety warnings, rate limits, or error behaviors expected from a file I/O tool.

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?

Single compact sentence with [PRO] front-loaded. Efficiently enumerates capabilities without redundancy, though slightly dense and lacking structural separation between read operations 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?

Complex multi-action tool (7 distinct operations) with nested query objects and file I/O capabilities. No output schema provided, yet description fails to hint at return formats (status object, config structure, history entries, file contents) or PRO requirements.

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% with detailed enum descriptions for each action. Description adds no parameter-specific semantics beyond schema, but schema adequately documents required/optional contextual parameters (placeId, instancePath). Baseline 3 appropriate.

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?

States specific capabilities (status, config, history, read/write) and identifies the resource (Project sync). Distinguishes from siblings (manage_assets, manage_scripts) via the 'sync' domain, though could clarify what 'sync' entails specifically.

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?

Lists capabilities but provides no guidance on when to use this tool versus siblings (manage_assets, manage_scripts) or the query/mutate tools. The [PRO] tag hints at licensing but lacks prerequisites or workflow context.

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