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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds genuinely useful behavior: the date defaults to today in Dubai timezone and the range is capped at 14 days. It does not describe result ordering or how the two night categories are combined.

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 front-loaded sentence with no filler; the defaults and cap are packed into the parenthetical. The em-dash-heavy structure is slightly dense but every clause carries information.

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?

An output schema exists, so return values need not be explained. For a simple, zero-required-parameter read tool, the description covers scope, timezone, defaults, and the cap — enough to invoke correctly. Only the meaning of 'signature nights' vs 'venue nights' is left undefined.

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 only 50% — 'days' has no schema description — and the description compensates by stating the default (7) and maximum (14) plus the minimum-implied range. The date parameter's default and Dubai timezone are also confirmed in prose, so both parameters are semantically complete.

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?

Names the specific resource ('the programme night by night') and its scope ('Dubai Table signature nights and venue nights'), which distinguishes it from sibling venue tools like list_venues. It is clear what an agent gets back conceptually, though it never states the return entity type (events vs. venues) explicitly.

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?

No when-to-use or when-not-to-use guidance, and none of the relevant siblings (list_venues, show_tables, request_table) are referenced. The agent must infer that this is the browsing/discovery tool from the name alone.

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