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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does add a useful behavioral trait by mentioning the daily quota of 20 comments per WIB day, but it does not explicitly state side effects, authentication needs, or error behavior. The mutation nature is implied by the verb 'Komentari' rather than stated.

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 concise sentence that front-loads the action and then adds the key quota constraint. Every word earns its place with no wasted content.

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?

Given three required parameters, no annotations, no output schema, and only 33% schema description coverage, the one-sentence description is insufficient. It omits the meaning of 'kunci', any usage prerequisites, and does not explain what happens on success or failure. The quota detail is valuable but not enough for confident invocation.

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%, with only 'isi' described as 'maksimal 2048 karakter'. The description text helps infer that 'pos' refers to the post being commented on, but 'kunci' remains completely unexplained, and no additional parameter context is provided to compensate for the low schema coverage.

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 'Komentari' (comment on) and a clear resource 'pos' (post), making the core action unambiguous. It does not explicitly differentiate from sibling tools, but the action is distinct enough that an agent can identify it as the commenting operation.

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 implies the tool is used to comment on a post, and the quota note ('jatah 20 per hari WIB') gives a usage constraint. However, it does not state when to prefer this tool over siblings like alun_pos or alun_tulis, nor does it mention exclusions.

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