Blinks Build Action Url

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

The description claims 'operation class read' but annotations set readOnlyHint=false, creating a contradiction. The tool builds a URL (likely no side effects), but the inconsistency undermines trust.

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 two sentences, but includes jargon like 'SAP MCP context' that may not help users. It could be more concise and front-loaded.

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 has an output schema (implied), the description doesn't need to detail output, but it fails to clarify the return value or how the URL is used in the broader action flow.

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%, so the description adds minimal value beyond the schema. It mentions wrapping in a Blink provider, which is already in the schema's blinkProvider description.

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 it builds and optionally wraps a Solana Action URL for sharing as a Blink. It distinguishes from siblings like blinks_getAction by focusing on URL construction, but the mention of 'operation class read' introduces slight ambiguity.

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?

The description provides some usage context ('Use for Solana Actions and Blinks metadata fetch, validation, and POST action preparation') but lacks explicit when-not-to-use or differentiation from alternatives like blinks_validateActionsJson.

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