podyx_v1_list_sessions

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false. The description adds meaningful non-obvious behavior: dates are studio-local, session IDs differ from booking IDs, status is derived while booking_status is persisted, original payment status covers only the first linked payment, and pagination must be followed. It does not address permissions or rate limits, but it goes well beyond the annotations.

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 front-loaded with the endpoint identity and then moves through scope, timezone, ID semantics, status semantics, payment status, read-only behavior, and pagination. Each sentence carries information, though the phrasing is dense and somewhat jargon-heavy ('fact-backed cancellations and roomless studio tours').

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 listing tool with a nested filter object and no output schema, the description covers safety, pagination, quote caveats, and some returned-field semantics. It still leaves the response shape and many filter-specific behaviors undocumented, which matters because there is no output schema to explain what a session payload contains.

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?

The schema contains many nested filter parameters, and several lack descriptions: page, search, status, date_to, room_id, client_id, and date_from. The description clarifies some semantics like studio-local dates and status vs booking_status, but it does not explain accepted status values, search behavior, date-bound behavior, or most filter semantics, so it does not compensate for the low schema description coverage.

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 states a specific verb and resource: 'listSessions GET /api/v1/sessions', and scopes it to history-aware sessions including cancellations and studio tours. It also distinguishes session IDs from booking IDs. It does not explicitly contrast with siblings like podyx_v1_get_session or podyx_v1_list_bookings, so it stops short of a 5.

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 gives useful usage constraints: 'Read/preview only', 'Follow all pagination', and 'a quote does not reserve a slot or lock a price'. However, it never says when to choose this tool over podyx_v1_get_session or podyx_v1_list_bookings, so usage guidance is implied rather than explicit.

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