TutorPing

Book a session with a tutor

request_booking

Book a student into one of a tutor's open slots (from get_tutor_availability). The tutor and the student both get a confirmation email. Confirm the time, name, and email with the user before calling.

A4.1/5.0

Behavior4/5

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

Annotations only declare openWorldHint and destructiveHint=false; the description adds real behavioral value beyond them by disclosing side effects (confirmation emails to both tutor and student) and the mandatory human-confirmation step before calling. It still does not say what happens on a failed or conflicting booking.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, zero filler, and the action plus data source are front-loaded before the operational constraint. Every sentence carries a distinct instruction.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no output schema, the description covers purpose, prerequisite source call, user-confirmation workflow, and side effects. It omits the result of a successful call and error handling for unavailable slots, which an agent would need for a booking flow.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 43% across 7 parameters, so the description needs to compensate but largely does not. It references time/name/email only as a confirmation checkpoint, leaving slug, subject, and type semantics entirely to the schema — and slug and subject have no schema descriptions at all.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Book a student into one of a tutor's open slots') and scopes it against the sibling that produces the slot data (get_tutor_availability). An agent can distinguish this from get_tutor_availability or search_tutors without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly ties invocation to output from get_tutor_availability and adds a required pre-call workflow: confirm time, name, and email with the user. It does not state any when-not conditions or failure-path alternatives (e.g., what to do if the slot is taken).

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