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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful behavioral context by disclosing what the payload contains (including page urls), but says nothing about pagination limits, result caps, or behavior when the company name is ambiguous or not found.

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?

It is two short, front-loaded sentences that lead with the resource and then enumerate returns. The Arabic and English halves are essentially duplicates, which doubles the token cost for monolingual agents, but the parallel phrasing is deliberate and nothing is padded or vague.

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 single-parameter, read-only lookup with no output schema and full annotation coverage, the description carries what is needed: it specifies the identifier and enumerates the returned fields. Only minor gaps remain (no coverage of empty/ambiguous results, no routing to siblings), so it is nearly complete.

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?

There is a single parameter with 100% schema description coverage, so the schema already documents that it accepts an Arabic company name or an id. The description only echoes 'by name or id' without adding format, ambiguity, or fallback guidance, so the baseline of 3 applies.

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 resource (a company's record in Saudi government tenders) and enumerates the returned dimensions: bids, wins, awarded value, top agencies, activities and recent wins. An agent can distinguish it from agency_summary by the word 'company', though the sibling contrast is never made explicit. It is clear but not fully differentiated in prose.

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 rather than stated: the enumerated outputs imply 'use this to profile a company's tender history', and 'by name or id' hints at the input. There is no explicit when-to-use, no exclusion, and no pointer to alternatives such as agency_summary for government bodies or search_tenders for discovery.

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