analyze_operators

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

The annotations already state readOnlyHint=true and idempotentHint=true, so the safety profile is covered. The description adds scope detail (creation functions, operators, performance patterns, best practices) but does not disclose how results are returned or what a typical analysis output contains. No contradiction with annotations.

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 that immediately identifies the action, target, and scope. There is no filler or redundant phrasing.

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 read-only analysis tool with well-documented parameters and helpful annotations, the description covers the core action. However, with no output schema, the description does not explain what the agent should expect as a result, and it gives no sibling comparison to guide selection among the listed alternatives.

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 documents all three parameters, including defaults for checkPerformance and includeAlternatives. The description aligns loosely with those parameters by mentioning performance patterns and best practices, but it adds no semantic detail beyond the schema.

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 ('Analyze') and resource ('RxJS code'), and names concrete analysis dimensions: creation functions, operators, performance patterns, and best practices. However, it does not explicitly distinguish itself from overlapping siblings like lint_rxjs or detect_memory_leak, so it is clear but not fully differentiated.

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?

No guidance is provided about when to use this tool versus alternatives such as lint_rxjs, detect_memory_leak, or suggest_pattern. Usage is only implied by the phrase 'Analyze RxJS code', with no exclusions, prerequisites, or routing conditions.

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