discord_set_channel_permission

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'Create or replace' indicating mutation, but it does not disclose that 'replace' overwrites existing permissions, does not mention required permissions (e.g., manage_permissions), and does not explain the dryRun parameter's safety behavior. This leaves critical behavioral gaps.

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 a single clear sentence with no wasted words, which is structurally fine. However, given the tool's complexity (8 parameters, critical behavior like dryRun), the description is under-specified and arguably too short to be 'appropriately sized.' It's concise but at the expense of necessary detail.

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?

There is no output schema and no annotations, so the description must be the sole source of context. It fails to explain return values, permission requirements, dryRun semantics, or the effect of replacing an overwrite. This makes the tool nearly unusable without external knowledge, so context is highly 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 provides zero parameter information beyond the schema. With schema description coverage at 0%, the description fails to explain what allow, deny, dryRun, reason, or targetType mean in practice. It only hints at targetType via 'role/member' but does not add any semantic value over the raw JSON schema.

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's purpose: 'Create or replace a role/member permission overwrite on a channel.' This is a specific action with a specific resource, and it distinguishes itself from sibling tools like discord_upsert_channel or discord_upsert_role by focusing on permission overwrites.

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 use case is implied: use when you need to set or replace a role/member permission overwrite on a channel. However, no explicit alternatives or when-not-to-use guidance is provided, so it relies on the reader to infer when this tool is appropriate.

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