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

Annotations already declare readOnlyHint/idempotent/non-destructive, so the safety profile is covered. The description adds genuinely useful detail beyond that: the ordering of returned items (top to bottom) and the per-block fields (id, type, content, shown) — information that matters because there is no output schema.

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?

Three sentences, but two of them are store-domain framing (ownership, Stripe, 'nothing is bought or sold in this chat') that delays the actual definition. The operative clause — what is listed and in what order — is buried at the end rather than 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?

For a single-optional-parameter read tool with no output schema, the description supplies the missing return-value picture (ordered blocks with id/type/content/shown) and the annotations cover safety. Nothing needed to call it correctly is absent.

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?

One optional parameter (workspaceId) with 100% schema description coverage, so the schema already carries its meaning. The description adds nothing about the workspace scoping or parameter behavior; 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+resource: it lists the blocks of the public link-in-bio store page, and adds ordering (top to bottom) and returned fields. It is clearly distinct in scope from add/delete/reorder/update_store_block, though it never names those siblings explicitly, so an agent must infer the boundary from the resource noun alone.

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?

Usage is only implied: the domain framing tells the agent this is about the store page structure, not checkout. There is no statement of when to call this versus get_store, update_store_block, reorder_store_blocks, or show/hide_store_block, and no prerequisites or exclusions are given.

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