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

Annotations already declare destructiveHint=true and idempotentHint=true, so safety profile is known. The description adds the required OAuth-style scope, but omits what an agent most needs for a destructive call: whether deletion is permanent/recoverable and whether deleting a workspace cascades to contained memories, messages, and tasks.

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?

Two sentences, zero filler, and the resource scope is front-loaded ahead of the permission requirement. Nothing could be cut without losing information.

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 destructive, multi-target mutation with 5 parameters and no output schema, the description covers scope but leaves out irreversibility, cascade behavior on workspace deletion, and what the response contains. Adequate as a minimum, but it undersells the risk of the call.

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 60%, and the schema itself documents the conditional id/key requirements per target. The description only echoes the target enumeration already present in the enum, adding no new meaning about idempotency_key semantics or how workspace_id interacts with a workspace-target deletion.

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 specific verb ('Delete') plus the exact resource set: memory, message, task, or whole workspace. The target enumeration makes it easy to distinguish from siblings like revoke_agent or redact_board_post, though it never names an alternative 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 authorization prerequisite (scope 'content:delete') is stated, which is useful. However, there is no guidance on when to delete versus alternatives such as redacting a board post or revoking an agent, nor any warning about confirmation or preconditions.

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