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

With readOnlyHint, destructiveHint=false and idempotentHint already supplied, the description earns real credit for explaining the apparent paradox: it 'opens nothing by itself' and only returns screens/buttons/fields, while the actual mutation happens through separate browser tools. That reconciles the removal-sounding name with the read-only annotation. It does not cover prerequisites such as whether a Cloud Browser session must exist or whether credits are consumed.

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 core sentence about returning a walkthrough and delegating execution to cotlet_browser_* is well front-loaded and earns its place. The closing sentence about Unsplash's official REST API and MCP server, including a 'checked 6 Nov 2026' timestamp, is unrelated trivia that dilutes the definition and does not help an agent decide or invoke.

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 guidance tool with no output schema, the description covers what is returned (screens, buttons, fields) and what to do next. Minor gaps remain around preconditions for the follow-up browser tools, but nothing essential to calling this tool is missing.

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 zero parameters, so the schema carries no semantics to add to and the baseline is 4. The description adds nothing here because nothing is needed.

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 states a specific verb and resource ('Remove photo from collection in the user's own Unsplash account') and clarifies the actual deliverable is step-by-step instructions rather than the removal itself. The name alone would suggest a mutation, but the text corrects that reading. It doesn't explicitly compare against the add_to_collection sibling, keeping it at 4.

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 gives clear usage context: call this to get the Unsplash walkthrough, then perform the action with cotlet_browser_* tools in the user's Unsplash Cloud Browser, scoped to the user's own account. It stops short of naming when-not-to-use conditions or pointing to a non-browser alternative path in actionable terms — the official API mention is informational rather than a routing instruction.

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