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

The description adds valuable behavioral context beyond the readOnlyHint annotation: it specifies what the tool detects ('modified, missing, or corrupted files'), mentions the checksum verification mechanism, and notes the Arch Linux limitation. While it doesn't cover rate limits or authentication needs, it provides meaningful operational details that aren't in the 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?

The description is efficiently structured with two sentences: the first states purpose and scope, the second provides usage guidelines. Every element serves a clear purpose with zero wasted words, and the [MAINTENANCE] tag appropriately signals the tool's nature.

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 verification tool with good annotations and full parameter documentation, the description provides adequate context about what the tool does and when to use it. The main gap is the lack of output schema, but the description compensates somewhat by explaining what gets verified. It could benefit from mentioning output format or result interpretation.

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?

With 100% schema description coverage, the input schema already fully documents both parameters. The description doesn't add any additional parameter semantics beyond what's in the schema, so it meets the baseline expectation but doesn't provide extra value.

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 specific action ('verify integrity'), target resource ('installed package files'), and scope ('only works on Arch Linux'). It distinguishes from siblings by focusing on file integrity verification rather than configuration analysis, security auditing, or package management operations.

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?

Explicitly states when to use ('After system crash or disk errors') and provides a concrete example ('verify linux package files match expected checksums'). This gives clear context for when this tool is appropriate versus other package-related tools.

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