seed_grant_permission

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

The description explains the core operation (creating a permissions row, linking it to a role) and provides the bitmask semantics. However, with no annotations, it carries the full burden and does not disclose whether the operation is idempotent, whether it replaces existing permissions, or whether the role must already exist.

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 two sentences, front-loaded with the action, and every piece of information earns its place. No wasted words or redundancy.

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?

With no output schema and no annotations, the description delivers the core purpose, mechanism, and bitmask semantics. While it omits return values and edge-case behavior, the schema is thorough and the operation is straightforward, making it largely complete for an agent to invoke.

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 schema covers all parameters (100%), but the description adds value by mapping the bitmask values (create=1, read=2, update=4, delete=8) for the 'access' parameter, which the schema only describes as 'Bitmask access value'. This goes beyond the schema's baseline.

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 ('Grant') and resource ('Seed resource'), plus the mechanism ('creating a permissions row and linking it to the role'). This clearly distinguishes it from sibling tools, none of which deal with permissions.

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 clearly implies when to use the tool (to grant a role access to a resource), and the sibling list contains no alternative permission-granting tool. However, it does not explicitly state exclusions or alternatives, so it falls short of a 5.

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