diff_vs_snapshot

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

No annotations provided, so description carries burden. It describes the comparison action but does not explicitly state non-destructive nature or error conditions. For a comparison tool, behavior is moderately clear.

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?

Two concise sentences, front-loaded with purpose. No wasted words; efficient and clear.

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?

Tool has one parameter, no output schema, no annotations. Description covers purpose and param context adequately but does not hint at output format. Overall adequate for a simple diff tool.

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?

Single parameter 'snapshot_path' has no schema description (0% coverage). Description adds context that snapshot must be in the directory from snapshot_state, which aids understanding but lacks format details or examples.

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?

Description clearly states 'compare the LIVE mixer state against a saved snapshot' with a specific verb and resource. Distinguishes from sibling tools like mixer_state and snapshot_state.

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?

Provides context that snapshot must be in the directory written by snapshot_state, implying usage after that tool. But lacks explicit when-to-use vs alternatives or when-not-to-use.

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