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

With no annotations, the description carries the full burden for a mutation tool. It does not disclose whether this is a full replace or a partial update of the existing config, what happens to already-collected fields when capture is disabled, or whether elevated permissions are needed.

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?

A single front-loaded sentence with no filler, using the colon to enumerate the two dimensions of the setting. It is dense but earns its words; slightly more structure would help disambiguate the defaults.

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?

Five parameters, zero schema descriptions, no annotations, and no output schema: the description should explain update semantics and defaults but does not. An agent could invoke it but cannot predict whether omitting a boolean resets it or leaves it untouched.

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 0%, so the description must compensate — and it partly does, mapping 'whether it's on' to enabled and 'which fields (name/email/phone) are required' to the three collect_* booleans. However, bot_id is unmentioned and the partial-update semantics of omitting optional booleans (which carry defaults) are not explained.

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?

States a specific verb and resource ('Configure in-chat lead capture') and names the actual settings controlled (on/off plus required fields), so an agent knows exactly what the call changes. No sibling tool in the list overlaps in function, so the lack of explicit sibling differentiation costs little.

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 never says when to reach for this tool versus related ones (e.g., list_leads/export_leads for reading captured leads) or what prerequisites exist. It gives only a bare statement of function with no conditions, exclusions, or sequencing.

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