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

The description discloses extra behavior beyond annotations by noting bulk support via project_ids. It also indicates this is a state-changing operation by describing 'Pauses', which is consistent with readOnlyHint: false. However, it does not cover what happens to the project after pausing, whether it is reversible, or what the response contains.

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 extremely concise: two short sentences with no filler. The main purpose is front-loaded, and the bulk execution detail is a separate, useful addition.

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?

It covers the core operation and bulk execution, which is the main contextual need. But for a state-changing tool with no output schema and sparse annotations, it does not describe side effects, restoration path, or response behavior, leaving some ambiguity for an agent deciding whether invocation is safe and appropriate.

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%, so the description must compensate. It does clarify that project_ids enables batched execution, which adds meaning beyond the raw schema. Still, it does not explain the relationship or optionality between project_id and project_ids, or the expected ID format.

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 uses a specific verb and resource: 'Pauses a Supabase project.' This directly states what the tool does and is not confused by any sibling tool, since no sibling is also named as a pause action.

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 implies when to use the tool: when a Supabase project should be paused. However, it does not explicitly mention when not to use it, nor does it point to related alternatives such as supabase_restore_project for resuming a paused project.

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