set_queue_access

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

Annotations only state readOnlyHint=false and destructiveHint=false; the description adds substantive behavior the annotations do not: whole-array overwrite versus delta semantics, and the constraint that deny applies only to users and groups. One caveat it leaves unstated is that array overwrite silently drops existing grants, which sits in mild tension with destructiveHint=false, but this is not a direct contradiction.

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?

Three short, information-dense sentences with no filler, and the core operation is front-loaded. Slightly telegraphic phrasing ('Arrays overwrite') costs a little readability but not correctness.

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 two-parameter nested-object mutation tool with no output schema, the description covers the semantics an agent actually needs to build the payload, including the overwrite/delta distinction. It omits any mention of required privileges or whether changes are reversible, which would round it out.

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?

With schema description coverage at 50% (queueId is bare, permissions carries only an inline example), the description compensates well by naming the valid permission keys, the valid principal keys, and the two accepted value forms. It still doesn't explain queueId's accepted string/number forms or the meaning of role names, so it falls short of fully covering the gap.

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?

States a precise verb+resource (change queue access rights) and enumerates the permission levels it manages (create/write/read/grant/deny) plus the principal types (users, groups, roles). It is clearly a mutation counterpart to siblings like get_queue_user_access and get_queue_group_access, though it never names those alternatives explicitly.

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 gives strong payload-shape rules (arrays overwrite; {"add":[],"remove":[]} applies deltas; deny supports only users and groups) which imply how to call it, but it offers no when-to-use guidance and no routing against the many sibling access tools (get_entity_permissions, update_entity_access, update_entity_permissions).

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