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

With no annotations provided, the description carries the full burden. It effectively discloses the destructive nature ('replaces existing entries'), authentication requirements, and concurrency control mechanism ('if_match... to prevent conflicts'). It does not mention idempotency or atomicity guarantees, but the output schema handles return value documentation.

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 well-structured with high information density. The two-sentence preamble front-loads critical information (operation type and auth requirements). The Args section follows logically, with no redundant or wasteful text.

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?

Given the 0% schema coverage and the tool's complexity (destructive mutation, auth-gated, concurrency-controlled), the description successfully documents all parameters and behavioral risks. A perfect score would require explicit mention of atomicity or rollback behavior, but the coverage is sufficient for safe 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?

With 0% schema description coverage, the description fully compensates by documenting all 4 parameters in the Args section. It adds critical behavioral context beyond types: 'entries' is explained as replacing existing data, and 'if_match' includes an example value ('v1') and explains its purpose (conflict prevention).

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 opens with a specific verb ('Replace') and clearly identifies the resource ('workspace') and scope ('entire content', 'name and entries'). It effectively distinguishes from siblings like read_workspace (read vs. replace), create_workspace (create vs. update), and delete_workspace (delete vs. modify).

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 provides clear authentication requirements ('Requires write key') and error conditions ('API will return 403 if a read key is used'), which are critical usage constraints. However, it does not explicitly state when to use this versus create_workspace or whether this is preferred over delete+create patterns.

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