Delimit Reddit Scan

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

Beyond the annotations (readOnlyHint, idempotentHint, destructiveHint), the description discloses read-only network access via residential proxy, a 1 req/2sec rate limit, and a mandatory tool-chaining rule after scanning. This adds substantive behavioral context that annotations alone do not provide.

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 well-structured and front-loaded: the core purpose appears first, followed by usage guidance, side effects, and the chaining rule. Every section earns its place and the text is dense without being bloated.

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?

The tool is fully contextualized for an agent: clear purpose, explicit alternative routing, side-effect disclosures, rate limiting, and a mandatory follow-up chain. With an output schema present and annotations covering safety, nothing essential is missing for correct invocation and follow-through.

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 description coverage is 100%, so the schema already fully documents the sort and limit parameters. The description does not add new parameter-level semantics, but this is acceptable because the baseline of 3 applies when the schema carries the load.

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: bulk scanning 25+ subreddits for outreach targets. It further distinguishes itself by stating it is venture-agnostic and returns ranked, categorized targets, which clearly separates it from sibling tools like delimit_social_target and delimit_reddit_fetch_thread.

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 provides explicit 'when to use' and 'when NOT to use' guidance, names the alternative tools by name, and includes a sibling contrast section. An agent can confidently route to this tool versus the alternatives without ambiguity.

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