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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so safety is covered and the description needn't repeat it. The description adds genuine value by enumerating the full status state machine and noting the two distinct response shapes per mode. However, it never addresses the zero-required-parameter design — what happens if both parameters are supplied, or neither — which is the main behavioral ambiguity for a caller.

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 compact sentences, the core purpose front-loaded, and the two access modes split cleanly across the second and third clauses. Slightly telegraphic phrase fragments ('Where a SaaSCity submission stands') but nothing is wasted.

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?

With an output schema present and read-only idempotent annotations, most of the burden is already carried elsewhere, and the description covers the domain states. The gap is the optional/optional parameter design: it never says whether the modes are exclusive or what is returned when no identifier is given, which an agent needs in order to call it correctly.

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%, so the baseline would be 3, but the description goes further by mapping each parameter to a different result: claim_token yields a claim-funnel state, slug yields live-listing attributes (launch week, badge, link type, points). That mode-to-output mapping is meaning the schema alone does not convey.

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 resource and operation: it reports where a SaaSCity submission stands, and enumerates the possible states (unclaimed, expired, in review, rejected, archived, live). It is clear what the tool returns, though it does not name sibling tools it might be confused with — notably get_listing, which it partially overlaps with in the slug mode.

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 through the two modes: use claim_token to track a claim through the funnel, use slug to inspect a live listing. There is no explicit when-to-use statement, no guidance on choosing this over get_listing or check_launch_readiness, and no exclusion cases.

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