analyze_pin_functions

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

With no annotations, the description partially discloses behavior (analyzes schematic, infers functions, detects conflicts), but does not state whether it modifies data, permissions needed, or other traits. Lacks full transparency.

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 concise with a clear bullet list. Each sentence provides relevant detail without redundancy, though the third bullet is slightly repetitive of the title.

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 the output schema exists, return values are handled. However, the description lacks context for when to choose this over similar analysis tools among many siblings, and does not explain the output's nature.

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 coverage is 100%, and the description adds minimal extra meaning beyond the parameter names and descriptions. The bullet list confirms the context but doesn't enrich parameter understanding.

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 analyzes pin functions and detects conflicts, listing specific methods like examining net names and identifying MCU components. It distinguishes from siblings like 'detect_pin_conflicts' by implying a broader analysis, though not explicitly differentiating.

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 on when to use this tool vs. alternatives like 'detect_pin_conflicts' or 'extract_pinmux_config'. The description only states what it does, not the context or prerequisites for its use.

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