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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the tool 'saves Claude context for strategic decisions' which hints at statefulness, but doesn't describe what the tool actually returns (output format), whether it modifies anything, performance characteristics, error conditions, or authentication needs. For an 11-parameter analysis tool with no annotations, this is inadequate.

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 uses a fragmented structure with separate sections (WORKFLOW, TIP, SAVES) that aren't well-integrated. The 'SAVES: Claude context for strategic decisions' sentence doesn't clearly relate to the tool's core functionality and feels like wasted space. The description could be more cohesive and front-loaded with essential information.

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 complex 11-parameter tool with no annotations and no output schema, the description is incomplete. It doesn't explain what the tool returns (crucial for an analysis tool), doesn't clarify the relationships between the many input options, and provides minimal behavioral context. The 'saves Claude context' hint is vague and doesn't compensate for the missing output information.

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 the schema already documents all 11 parameters thoroughly. The description doesn't add any parameter-specific information beyond what's in the schema. The baseline is 3 when schema does the heavy lifting, though the description could have explained relationships between parameters like 'code' vs 'filePath' vs 'files'.

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 purpose: 'Compare method signatures between caller and callee to identify parameter mismatches and provide actionable fixes.' This specifies the verb (compare), resource (method signatures), and outcome (identify mismatches, provide fixes). However, it doesn't explicitly differentiate from sibling tools like 'analyze_single_file' or 'list_functions' which might overlap in code analysis.

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 provides some usage context with 'WORKFLOW: Perfect for understanding complex code, identifying issues, and technical debt assessment' and 'TIP: Use Desktop Commander to read files, then pass content here for analysis.' This implies when to use it (for code understanding/technical debt) and a workflow tip, but doesn't explicitly state when NOT to use it or name alternatives among the many sibling tools.

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