Share an album by link

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

The description adds material behavioral context beyond the annotations: the link cannot be recalled once sent, unshare_album cannot retract content already saved by others, and confirm:true is required. This aligns with and enriches destructiveHint=true and openWorldHint=true, giving the agent a realistic sense of consequence before invoking.

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 three short sentences, with the core effect front-loaded and the risk-related caveats placed immediately after. Every sentence adds distinct value: what it does, why it is unique, and what irreversible consequence to expect.

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 tool with no output schema, the description still names the return value (a link). It covers uniqueness, irreversibility, the related unshare tool, and the confirmation guard. Combined with full schema coverage and rich annotations, no critical operational detail 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?

Schema description coverage is 100%, so the schema already documents album_id, account, confirm, commentable, and collaborative. The description reinforces the confirm requirement, but does not add detail about parameters beyond what the schema provides. Baseline 3 is appropriate.

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 opens with a specific verb and resource: 'Turn an album into a shared album and return a link anyone can open without signing in.' It clearly distinguishes this from siblings by noting it is 'the one thing here that reaches people outside the account,' which separates it from create_album, update_album, and other internal operations.

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 explicitly states the unique use case: sharing with people outside the account. It also provides a direct alternative comparison with unshare_album, explaining the limitation that revoking cannot recall content already saved. This gives an agent clear routing guidance without needing to inspect other tools.

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