plsreadme_update

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

Adds context beyond annotations: authentication via local file, alternative identifiers. Consistent with idempotentHint=true and readOnlyHint=false. No contradictions.

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?

Two sentences, first states action, second details requirements. No redundant information, highly efficient.

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?

Covers action, required params, and identification method. Lacks error handling details or return type, but sufficient for a simple update tool with idempotent hint.

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 coverage is 100%, baseline 3. Description adds meaning by clarifying id and file_path are alternatives, not both required. Enhances understanding of parameter relationships.

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 'Update' and the resource 'existing plsreadme document'. It distinguishes this tool from siblings (delete, list, share) by specifying content update.

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?

Provides guidance on required parameters (either id or file_path) and mentions a prerequisite (admin token lookup). Could explicitly state when to use vs alternatives, but siblings are distinct actions.

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