Software Estimation MCP

Wbs Breakdown

wbs_breakdown

Generate an initial work breakdown structure from a software requirement and work type (feature, bugfix, legacy_patch, refactor, integration) for estimating scope.

Instructions

Genera una WBS inicial para feature, bugfix, legacy_patch, refactor o integration.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says only that an initial WBS is generated and does not state whether the tool is read-only, whether it creates persistent state, what side effects occur, or what output is returned beyond the existence of an output schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that front-loads the core action and resource. Every element (verb, resource, scope) earns its place with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has low complexity (2 parameters, no nesting) and an output schema, so the description need not explain return values. Still, with no annotations and 0% schema descriptions, it should at least clarify the requirement_description parameter and basic usage context. It covers the core purpose but leaves important gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

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. It provides useful accepted values for the work_type parameter (feature, bugfix, legacy_patch, refactor, integration), partially addressing that gap. However, it offers no meaning or format for the required requirement_description parameter, leaving half the parameters undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Genera') and resource ('WBS inicial') and enumerates the work types it covers. It does not explicitly differentiate itself from siblings like generate_roadmap or calculate_pert, but the purpose is clear enough to distinguish it from most others.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description lists work types but provides no guidance on when to use this tool versus alternatives such as generate_roadmap or calculate_pert. There is no mention of prerequisites, context, or exclusions.

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