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

With no annotations, the description carries the full burden and does so thoroughly. It discloses the workflow (crawl, buyer identification, Reddit mining), the deliverable (report link), the timing (~2-3 minutes), and the rate limit (2 runs/day). This is exceptional behavioral transparency for a tool with no annotation metadata.

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 three sentences, each adding essential information: the process, the result access via get_demo_report, and the rate limit. There is no filler or repetition, and the most important action (submit URL, get threads) is front-loaded.

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 tool with 2 parameters and no output schema, the description fully explains the workflow, the return value (report link), and the expected timing. It also mentions the daily limit and points to get_demo_report for retrieval, making it self-sufficient for an agent to invoke and follow up.

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 100% with descriptive parameter texts for both website_url and email. The description adds minimal extra semantic value beyond what the schema already provides, such as 'give it a product website URL.' This matches the baseline expected when the schema fully documents parameters.

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 clearly states that the tool takes a product website URL, crawls the site, identifies buyer personas, and mines Reddit threads for buyer questions. This specific verb+resource+outcome distinguishes it from siblings like get_demo_report (which retrieves results) and reddit_demand_board (which likely shows broader demand).

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 clear context: use this when you have a product URL and want a free GTM demo of buyer conversations. It also explicitly mentions the 2-run daily limit and the companion tool get_demo_report for retrieving results, but it doesn't explicitly state when not to use this tool versus alternatives.

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