Decode Cloudflare Email

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

No annotations are provided, so the description carries the full behavioral burden. It implies a pure transformation, but does not state that it is read-only, what happens with malformed input, or any error behavior. The output schema covers the return shape, which reduces the gap.

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?

One sentence, front-loaded with the action and resource, with no wasted words. The parenthetical adds precise input guidance without bloat.

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 single-parameter decoding utility with an output schema, the description gives enough context to invoke it correctly. Minor gaps around malformed-input handling remain, but the essential input semantics are covered.

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 0%, so the description must compensate for the lone parameter. It does so well by explaining exactly what 'encoded' should contain: the data-cfemail value or the substring after '#'.

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 ('Decode') and resource ('Cloudflare email-protection string'), and it clarifies the exact input forms (data-cfemail value or the part after '#'). This is sufficiently distinct from the sibling lead/scraping tools.

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?

Usage is implied by the input format: use this when you have a Cloudflare email-protection string. There are no explicit when-to-use/when-not-to-use instructions or named alternatives, but the siblings are unrelated enough that extensive routing guidance is less necessary.

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