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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds meaningful behavioral context beyond that: it returns procedural guidance only, opens nothing by itself, and requires a follow-up browser action. It does not cover auth requirements or rate limits, but for a zero-parameter guide tool this is informative.

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 first two sentences are front-loaded and useful, but the final sentence about SmugMug's REST API v2 and the absence of an MCP server is tangential to invoking this tool. The 'from ChatGPT, Claude or any AI agent' phrase is also filler. The core instruction is clear, but the description carries unnecessary baggage.

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 zero-parameter, read-only guidance tool with no output schema, the description is largely complete: it explains what is returned, that nothing is opened automatically, and how to proceed afterward. It could be slightly stronger by naming the exact precondition for when an order is in proof delay, but nothing critical is missing for correct invocation.

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 tool takes no parameters, so there is nothing for the schema to document and no parameter semantics to explain. The baseline for zero-parameter tools applies, and the description adds no misleading parameter information.

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 names a specific resource and action (releasing an order in proof delay) and then clarifies the actual deliverable: step-by-step instructions with screens, buttons, and fields. It also distinguishes itself from the cotlet_browser_* tools, which perform the action. The initial phrasing mirrors the tool name and could momentarily suggest execution, but the second sentence resolves that.

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 establishes a clear workflow: this tool returns the how-to, then the agent should use cotlet_browser_* tools in the user's SmugMug Cloud Browser to carry it out. It does not explicitly state when to avoid the tool, but the read-only guide nature and the named follow-up tool family give sufficient context for selection.

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