sigma_grant_workspace_access

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

Annotations already indicate readOnlyHint=false, idempotentHint=true, and destructiveHint=false, but the description adds no additional behavioral context. It does not explain what happens on repeated grants, whether existing permissions are overwritten, or any side effects, missing the opportunity to complement the structured metadata.

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 and front-loaded, with no filler text. The parameter value list is directly useful and structured, though it could be expanded slightly without becoming verbose. It earns high marks for brevity and layout.

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 mutation tool with four required parameters and an output schema, the description is too sparse. It lacks context on the effect of the grant, any prerequisites, or how this relates to other permission tools. The output schema covers return values, but the operational context is incomplete.

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?

The description explains the allowed values for grant_type and permission, which adds meaning beyond the bare schema. However, workspace_id and grantee_id are left entirely unexplained, and with 0% schema coverage, the description only partially compensates for the missing parameter documentation.

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 states 'Grant workspace access' with a specific verb and resource, making it clear what the tool does. It does not explicitly distinguish it from sibling tools like sigma_grant_workbook_access, but the workspace focus is implicit in the name and description, giving it adequate purpose clarity.

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 no guidance on when to use this tool versus alternatives, no mention of prerequisites, and no exclusions. It simply states the action and parameter values, leaving the agent without context for selecting this tool among many grant-related siblings.

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