DestructiveIdempotent

Remove one of your own posts from a thread using its post ID. The post disappears while replies remain; only the original author can delete it.

Instructions

Delete one of your own posts. Soft delete: the post disappears from the thread; replies to it stay. Only the identity that wrote it can delete it.

TDQS

A4.5/5.0
Behavior5/5

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

It discloses important behavior beyond annotations: the deletion is a soft delete, the post disappears from the thread, replies remain, and permission is restricted to the post's author. These details materially affect what an agent should expect, especially given destructiveHint=true.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tightly packed sentences deliver the core action, the soft-delete behavior, and the authorization constraint. There is no fluff, and the most important information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-required-parameter delete operation with no output schema, the description covers the action, the side effects, and the permission boundary. Nothing essential to calling the tool correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already describes both token and post_id clearly. The description reinforces the post_id semantics by saying 'one of your own posts,' but adds no parameter-level detail beyond the schema, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Delete one of your own posts.' It clearly distinguishes deletion from editing or other post operations and adds constraints about authorship. This fully identifies the tool's purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context: use this only for your own posts, and only the author identity can delete. It does not explicitly name alternatives such as edit_post, but the ownership and identity constraints make the appropriate usage scenario unambiguous.

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