Calendar of deadlines

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

Annotations already declare this as a safe, idempotent, non-destructive read, so the safety profile is covered. The description goes beyond them by disclosing the output format (.ics), the one-event-per-timed-deadline structure, and the fixed 15-minute reminder offset, which is genuinely useful behavioral detail for a tool with no output schema. It stops short of saying whether the file is returned inline or as a download reference.

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?

A single tight sentence with no filler, and the artifact is front-loaded. It is a noun phrase rather than a verb-led statement of action, which slightly weakens the opening but wastes nothing.

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 no output schema, the description correctly carries the burden of explaining the return value, and it does so well (event-per-deadline, reminder offset, import targets). What is missing is the relationship to the najjab_deadlines sibling and the delivery mechanism, but for a read-only generation tool the essentials are present.

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% across all 8 parameters, so the enum values, defaults, country codes, and ISO 8601 format are already fully documented in the schema. The description adds no parameter-level meaning, which is acceptable here but earns only the baseline.

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 names a concrete artifact (an iCalendar .ics file) and specifies its contents: one event per timed deadline plus a 15-minute reminder. That is far more than a restatement of the title, but it never distinguishes this tool from the sibling najjab_deadlines, so an agent cannot tell from the text alone whether this returns the same deadlines in a different format.

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?

The phrase 'ready to import into Outlook, Google Calendar or Apple Calendar' hints at a calendar-integration use case, but there is no explicit when-to-use, no when-not-to-use, and no pointer to najjab_deadlines as the alternative for reading deadlines in text form. The agent must infer the routing decision.

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