discord_grant_permission

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

With no annotations, the description carries full burden. It discloses that it reads current permissions and ORs them (non-destructive), but does not mention required permissions, rate limits, error handling, or side effects like event triggers.

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?

Single sentence, front-loaded with action and key behavior. Could integrate parameter clarifications without becoming verbose.

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?

No output schema, simple structure. Description explains core operation but omits usage context, prerequisites, error handling, and return format. For mutation tool with 3 required params, it 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?

Schema coverage is 0%, but description mentions 'permissions by name' and provides an example. However, roleId is an ID, not a name, creating ambiguity. Does not explain guildId or permissions format beyond the example.

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 clearly states the tool adds permissions to a role, with an example permission (BAN_MEMBERS). It distinguishes from sibling tools like revoke_permission by specifying 'reads current perms and ORs in the new ones — does not clobber existing perms.'

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?

No explicit guidance on when to use this tool vs alternatives like discord_set_channel_permission or discord_edit_role. The description lacks context about prerequisites (e.g., requiring 'manage roles' permission) or when not to use it.

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