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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety bar is lower. The description earns credit by defining what is actually destroyed (the live product page listing, not the frame asset), that the frame survives and can be re-approved until expiry, and that a human confirmation is expected first — context no annotation conveys. It stops short of describing permissions, error cases, or what happens on non-Shopify channels.

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, front-loaded with the action and its effect, then the reversibility caveat, then the confirmation instruction. No filler and no repetition of the title.

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 single-parameter mutation with full annotation coverage and no output schema, the description covers effect, reversibility and the human-approval prerequisite. The one gap is the return value and whether removal can fail (e.g. already-removed or expired frame), though idempotentHint partly covers the former.

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% and the sole parameter already carries a description pointing at list_shoots. The tool description adds nothing about frame_id beyond the 'approved' qualifier, which the schema itself states. Baseline 3 applies.

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?

States a specific verb and resource ("Takes an approved frame back off its product") and immediately scopes the effect to Shopify live product pages. The mention of the frame being kept and re-approvable distinguishes it cleanly from the sibling approve_frame.

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 implies the usage context (only approved, currently-attached frames) and gives one explicit procedural rule, "Ask the person before removing." It never names an alternative or a when-not condition, so the routing guidance is implied rather than stated. Without a stated alternative the agent must infer that re-approval, not removal, is the way to restore a frame.

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