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

With no annotations, the description must disclose behavior itself, but it only says the post is flagged 'for the house'. It does not state consequences, reversibility, permissions, or whether the flag is visible to the author, so the agent cannot anticipate side effects.

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 entire description is one sentence with no filler; the primary action and the reason qualifier are front-loaded. Every word contributes.

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 three-parameter mutation tool with no annotations and no output schema, this is incomplete. Missing behavioral effects, pass semantics, and whether reason is strongly expected leave an agent guessing about the invocation context.

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 only 33% (pass), and the description does not compensate. It loosely maps 'a post' to postId and 'with a reason' to reason, but it leaves pass unexplained and even creates ambiguity by suggesting a reason is expected while the schema marks it optional.

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 uses a specific verb ('Flag'), a clear target ('a post'), and mentions the reason parameter, so an agent can identify the core action. It does not explicitly name a sibling alternative, but 'for the house' adds a destination that distinguishes it from ordinary posting/reply tools in the sibling list.

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 guidance is given on when to choose flag over another tool, what kinds of posts should be flagged, or whether the action is for moderation/abuse only. The usage context is only implied by the verb, with no exclusions or alternatives.

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