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

Beyond the annotations, the description discloses that processing happens locally in the browser and that results include real-time highlights and group captures. This adds useful behavioral context without contradicting the idempotent/non-destructive 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 core information is compact and front-loaded, but the 'Regex Tester:' prefix repeats the tool name, and there is a duplicated period after 'captures..'. The canonical URL is useful but slightly tangential to invocation.

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 simple three-parameter utility with full schema coverage and an output schema, the description is sufficiently complete. It covers the tool's purpose, processing locality, and key output behavior; an example would be nice but is not essential for correct invocation.

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?

The input schema already documents all three parameters with descriptions, so the baseline is 3. The tool description adds general behavior but no per-parameter detail beyond what the schema already provides.

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 the tool tests regular expressions and highlights matches/captures, which is a specific verb and resource. It clearly distinguishes itself from the surrounding business/document tools, though it doesn't explicitly contrast with a regex-related sibling.

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 when-to-use or when-not-to-use guidance is provided. 'Local browser processing' hints at a privacy/context advantage, but the description never says 'use this when validating a regex before deployment' or names any alternative tool.

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