C2.9/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is covered. The description adds genuinely new context beyond that: it changes community state and requires confirm=true for a user-requested action, which is a meaningful gating requirement an agent must honor. It stops short of describing what side effects or related state changes occur.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded, with no filler. However, the opening sentence is pure restatement of the title, so the space it occupies is not fully earned. Still, the text is tight and appropriately sized.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, non-idempotent tool with 50 parameters, nested objects, no output schema, and three mutually exclusive body-input modes, two sentences is far too thin. It omits required payload fields (space_group_id, name, slug), the exclusivity rules between payload/payload_file/body flags, and any notion of the return value. The description is incomplete for the tool's complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 50 parameters, 58% schema coverage, 10 enums, and nested objects, the description is almost silent on parameters. The only parameter it mentions, confirm, is already fully documented in the schema. It never clarifies the critical payload vs. body-flags vs. payload_file distinction, nor the account selector, leaving the agent to reverse-engineer the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first sentence, 'Create Space,' is a verb+resource but essentially restates the tool name and title verbatim. It does not distinguish this tool from close siblings such as create_space_group, update_space, or create_event, all of which appear in the sibling list. An agent can infer the basic purpose from the name alone, so this is minimally viable rather than clarifying.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description offers no when-to-use vs when-not guidance and never names an alternative (e.g., create_space_group for grouping, update_space for edits). The only usage-adjacent statement concerns the confirm flag, which is more of a parameter rule than a selection guideline. An agent gets no help choosing this tool over its siblings.

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