ascii_table

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

The description discloses that it returns decimal, hex, binary, and character values. It does not detail potential side effects, but since it's read-only, that's expected. No annotations exist, so the description carries the full burden, but it provides minimal extra behavioral context beyond the obvious.

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 a single focused sentence plus a parameter note. It is front-loaded and concise with no wasted words.

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 tool with no parameters and an output schema, the description fully covers what the tool does and what it returns. No additional context is needed.

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?

There are no parameters, so baseline is 4. The description explicitly states 'no parameters needed', which adds clarity beyond the empty schema.

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 verb 'Get', resource 'complete ASCII table', and specifies the columns (decimal, hex, binary, character). This distinguishes it from sibling tools, none of which provide an ASCII table.

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?

It indicates when to use (to get the ASCII table) but does not explicitly mention when not to use or provide alternative tools. However, given its simplicity, the implied usage is clear.

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