text_ascii_table_post

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds behavioral context: 'Runs locally with no external input: read-only, non-destructive, offline, and rate-limited.' This enhances transparency beyond 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 comprised of 4 sentences, each essential. It front-loads the core purpose and efficiently covers scope, alternatives, and behavior. No unnecessary words or redundancy.

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?

Given the tool's role as a reference table generator with two parameters, the description covers output details (table array plus meta summary), parameter effects, and relevant alternatives among many siblings. The presence of an output schema offloads return value details, making the description appropriately complete.

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 has full description coverage for both parameters. The description adds meaning by explaining the effect of format (standard vs html) and extended (include 128-255) in context of the output, without repeating schema details verbatim.

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 explicitly states that the tool generates the full ASCII character reference table, detailing what it covers (code points, values, glyphs, etc.). It clearly distinguishes from siblings like text_hex_ascii_converter and conversion_number_base.

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 provides explicit when-to-use (complete lookup table) and when-not-to-use (for converting specific strings, use alternatives). It also states that it requires no external input, giving clear context.

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