validate_business_context_completeness

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

Without annotations, the description must disclose behavioral details. It states the tool returns 'a clear message indicating whether the business context is complete or what features are still missing,' which clarifies the output behavior. However, it does not disclose whether the operation is read-only, whether it has side effects (like logging), or any prerequisites beyond the phase context. The mention of 'ctx: MCP context for logging and error handling' hints at possible logging, but it's not explicit.

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 well-structured with an initial purpose sentence, then a validation message explanation, and a docstring-like Args/Returns section. It is front-loaded and every sentence adds context. No wasted words.

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?

Given zero parameters and an output schema that presumably describes the return value, the description adequately covers the tool's function and usage timing. It mentions validation before the next phase, which ties it to the phase-based workflow. It could be improved by mentioning what to do if validation fails (e.g., use set_business_context), but that's not strictly necessary.

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?

The input schema has zero properties, so there are no user-facing parameters to describe. The description's 'Args: ctx' section is technically misleading because `ctx` is not in the schema; it appears to be an internal context parameter. Since the schema covers 100% of parameters (none), the description adds no helpful parameter semantics and could confuse the agent about whether to pass `ctx`.

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 the tool's function: 'Validate that all business context features are set before proceeding to next phase.' This distinguishes it from sibling tools like set_business_context or get_business_context_features by focusing on completeness validation. The verb 'validate' and resource 'business context features' are specific and unambiguous.

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 specifies when to use the tool: 'before proceeding to next phase,' which is a clear trigger context. However, it does not explicitly mention alternatives or when not to use it, such as 'use get_business_context to inspect values' or mention that this is a gate check before advance_phase. So it provides context but no exclusions.

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