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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety behavior is covered. The description adds useful substance by naming the output artifacts (milestones, owners, dates) and the buyer/seller alignment intent, but says nothing about how it treats the many optional inputs or what the generated plan looks like.

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?

Two tight sentences with no waste, front-loading the core action and outputs. Slightly under-developed rather than padded, but structurally clean.

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?

With no output schema and 11 inputs (only 2 required), the description should ideally clarify how it behaves when optional context like champion, economic buyer, or blockers is omitted. It conveys the deliverable but omits that behavioral nuance, leaving it merely adequate.

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% across 11 parameters, so field meanings are fully documented in the schema and the description does not need to repeat them. It adds no syntax, format, or dependency detail beyond that baseline.

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 (generate) and resource (collaborative/mutual close plans) and lists the produced artifacts (milestones, owners, dates). It is clear what the tool does, but it never distinguishes itself from nearby siblings such as deal_strategy_coach or account_plan_builder, leaving the agent to infer the boundary.

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?

There is no explicit when-to-use guidance and no alternative tool is named. The phrase 'path to decision' implies late-stage deal planning, but the agent gets no condition telling it to pick this over proposal_section_writer or pricing_negotiation_guide.

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