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

The description adds useful behavioral context that annotations don't carry: the analysis is AI-driven and it mutates the customer's business context fields. However, it never flags that this can destroy existing data, even though destructiveHint=true, and the overwrite semantics are left entirely to the schema parameter. No mention of latency, cost, failure behavior when a URL is unreachable, or whether the result is deterministic.

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?

Three short, front-loaded sentences with the action stated first and supporting rationale afterward. The final sentence is somewhat filler for an agent, but nothing is redundant or 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?

For a destructive, AI-backed mutation with no output schema, the description covers what is extracted but omits what the caller gets back, what happens to pre-existing values (beyond the schema's overwrite flag), and error paths. Annotations plus a fully documented schema keep it serviceable, but the prose leaves the agent guessing about post-call state.

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%, so url, overwrite, and customerId are all fully documented in the schema, including the destructive overwrite semantics and the superadmin restriction. The description adds only the target field names (industry, objectives), which is marginal beyond what the schema already conveys, so the baseline 3 applies.

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 names a specific verb and resource -- extract business context (industry, objectives) from a company website URL -- and even specifies the extracted fields, so an agent knows exactly what it does. It doesn't explicitly contrast itself with any sibling, but no near-duplicate exists in the tool list (get_settings/update_settings are the closest manual alternatives and are never referenced).

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?

Usage is only implied via the rationale 'This helps the optimization agent understand the business better', which hints at the scenario but never states when to call it, what prerequisites exist (e.g., customer must already exist), or when manual context entry is preferable. No exclusions or alternatives are named.

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