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

With no annotations, the description carries the full burden. It discloses async queuing, execution via the user's Chrome, no API/credentials, return of a jobId, success permalink, and user prerequisites. This is comprehensive behavioral disclosure.

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 dense but every sentence adds information: mechanism, URL constraint, no-API distinction, async behavior, polling target, success output, and prerequisites. There is no filler or repetition.

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 3-param tool with no output schema and no annotations, it explains mechanism, prerequisites, async polling, and return values. The only meaningful gap is the undocumented idempotencyKey, which prevents full completeness.

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 has 0% description coverage, so the description must compensate. It adds meaning for targetUrl (must include /comments/) and text (reply text), but idempotencyKey is never mentioned and its purpose is left to the agent to infer.

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 opens with a specific verb and resource: 'Queues a Reddit comment/reply'. It also disambiguates from siblings by explicitly stating it does not use the Reddit API and runs via the paired Claw Post extension, making it clear this is a comment action rather than create_post or get_post_status.

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?

It gives explicit prerequisites (logged-in Chrome, paired extension, Chrome open), a URL constraint (must include /comments/), and directs polling with get_post_status. It does not explicitly contrast with create_post, but the comment-versus-post distinction is strongly implied by the title and 'comment/reply' language.

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