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

Goes well beyond the annotations by disclosing irreversibility ('Cannot be undone'), the address carry-over side effect, the default per-call confirmation and how to disable it, the need to confirm with a human because it 'reaches other people', and the required Cotlet API key scope. Note a mild tension: destructiveHint=false while the text says the action cannot be undone.

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?

Heavily redundant: 'Turn a won lead into a project; the lead address becomes the project address' is restated verbatim as 'Converts a lead to a project and carries the lead address over as the project address', and 'Cannot be undone' is restated as 'cannot turn a project back into a lead'. The useful safety and auth facts are buried after the duplication.

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 one-shot conversion with no output schema, the definition covers the key agent needs: irreversibility, human confirmation, auth scope, and optional inputs. It is close to complete, only lacking a note on what the returned project looks like or an explicit sibling pointer.

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 lead_id, estimated_start and estimated_revenue are already documented. The description adds only that estimated_start and estimated_revenue are optional and that the lead's address is propagated, which is marginal beyond the schema. 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?

States a specific verb and resource ('turn a won lead into a project'), and adds the concrete side effect that the lead address becomes the project address. It is distinguishable from houzz-pro_create_lead and houzz-pro_update_lead_stage by the win/convert semantics, though no sibling is named explicitly.

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 phrase 'a won lead' implies the precondition for use, and 'Houzz Pro cannot turn a project back into a lead' warns against mistaking it for a reversible step. However there is no explicit when-to-use vs alternatives guidance (e.g. versus update_lead_stage for leads not yet won).

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