encoding_decoding_ascii85

Encode binary data to ASCII text or decode ASCII85 back to binary using the Adobe PostScript ASCII85 algorithm.

Instructions

Menu ID: ascii85. ASCII85 Encoder/Decoder. Free online ASCII85 (Base85) encoder and decoder. Convert binary data to ASCII text format using Adobe PostScript ASCII85 encoding algorithm. Use describe_tool with tool_id "ascii85" for full page guidance.

Behavior2/5

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

With no annotations, the description fails to disclose behavioral traits like idempotency, side effects, or rate limits. It mentions conversion but doesn't confirm read-only nature or other constraints expected from a conversion tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is fairly concise but includes unnecessary text ('Menu ID: ascii85', 'Free online'). It front-loads the purpose but could be streamlined. The reference to describe_tool adds length without value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (3 required params, nested object, no output schema), the description is severely incomplete. It fails to explain the operation parameter's values, the options object's booleans, or the return format, relying on an external tool for essential details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds no meaning to the parameters. The 'text', 'operation', and nested 'options' object remain undefined, forcing the agent to infer from the tool name or resort to describe_tool.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as an ASCII85 encoder/decoder, specifies the algorithm (Adobe PostScript), and distinguishes it from siblings by naming the encoding type. However, it doesn't explicitly state that the 'operation' parameter controls encode/decode, leaving slight ambiguity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not provide guidance on when to use this tool versus siblings like base64 or hex encoding. It only redirects to describe_tool for more details, offering no context on appropriate use cases or when not to use it.

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