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

No annotations are provided, so the description carries the full disclosure burden, and it discloses almost nothing: no output format, no indication of what data the input must contain, no limits or prerequisites. "Plot a portfolio" implies a visualization-style output but never confirms or describes it.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though the brevity borders on under-specification rather than true conciseness.

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 no annotations, the description should tell the agent what to supply (e.g., portfolio entities, market growth, relative share data) and what comes back. A one-line generic sentence leaves both unanswered for a framework that typically needs structured market data.

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% and the single parameter is documented as "Your problem, decision, project, or question to analyze with this framework." The description adds no syntax, format, or content guidance beyond the schema, 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 states a specific verb ("Plot") and a well-known named framework (BCG Growth-Share Matrix), which naturally distinguishes it from siblings like run_swot or run_five_forces. It stops short of explaining scope or what the plot actually produces, so it is clear but not fully differentiated in intent.

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 when-to-use guidance and no comparison to the many sibling framework tools (run_swot, run_value_chain, run_scenario_planning, etc.). An agent gets no help deciding when a BCG matrix is the right framework versus an alternative.

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