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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful domain context (report stage values in_progress/preliminary/final, and the metric families returned), but says nothing about data freshness, latency, or the effect of querying a future/empty month.

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?

Each language version is a single front-loaded sentence with no filler, which is good. But the Arabic and English text convey essentially the same content, so the description is roughly twice the necessary length for an agent consuming it.

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 one required parameter, no output schema, and annotations covering the safety profile, the description carries the burden of describing the return shape — and it does enumerate the report's components (volume, change, agencies, activities, awards, values, stage). Only the stage enum's implications and edge cases for empty months are left unstated.

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% and the single 'month' parameter carries both a pattern and a 'YYYY-MM' description, so the schema does the heavy lifting. The description only echoes the month scoping without adding semantics such as timezone, allowed range, or behavior for the current month.

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 deliverable (monthly Saudi tender market report) and enumerates its contents: volume and change, top agencies/activities, awards and values, and stage. This is clearly distinct from entity-scoped siblings like agency_summary and company_summary, though the description never explicitly names those alternatives to sharpen the contrast.

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 implied by the name and the 'YYYY-MM' scoping — an agent can infer this is the tool for a periodic market-level rollup rather than a per-entity lookup. However, there is no explicit when-to-use, when-not-to-use, or routing guidance versus agency_summary/company_summary/open_tenders.

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