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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint false. Description adds the precondition that gifts are already chosen and references the Oda Juwotda service, but doesn't disclose additional side effects, limitations, or dependencies beyond annotations. With annotations carrying the safety profile, this is adequate but not rich.

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-loads purpose, then usage guidance. The 'Oda Juwotda(오다 주웠다)' phrase is unexplained and may be noise, but overall is efficient.

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 read-only tool with full schema coverage, output schema, and strong annotations, the description covers purpose and usage. It doesn't explain return format, but output schema exists; it doesn't discuss prerequisites beyond 'already chosen', which is stated. Minor gap: no mention of how limit interacts with results, but schema has default.

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 has 100% coverage, so baseline 3. Description repeats gift_ids but adds no extra semantics for parameters like minutes_until_meeting or transport_mode beyond what schema already provides.

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?

Description opens with 'Finds pickup stores and detour times' – a specific verb and resource. It also scopes to 'gifts that are already chosen (gift_ids)', distinguishing from recommend_gifts (narrowing candidates) and plan_rush_gift (all known from start).

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?

Explicitly states when to use: as a follow-up after recommend_gifts. It also names the alternative plan_rush_gift and the condition under which that sibling alone suffices. This gives an agent clear decision rules.

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