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

Annotations already declare readOnlyHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered; the description redundantly restates 'Read-only' but adds genuinely new behavior: a refusal rule for personal-status topics and a privacy constraint against client data. That refusal semantics is the valuable disclosure.

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?

Three short sentences, front-loaded with the scope, then the safety hint, then the input rules. Every sentence carries information, though 'Read-only' duplicates the annotations and is the one low-value clause.

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 tool with no output schema, the description covers scope, input expectations, and refusal conditions adequately. What is returned (link format, ordering, count) is unspecified, but that is a minor gap for this tool's complexity.

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 'topic' param is documented as 'Topic to match against published pages', which the description essentially repeats. The 'not client data' note adds a small usage nuance but no format or matching-syntax detail beyond the schema, so baseline 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?

States a specific verb and resource ('List official legislation links') plus a scoping constraint ('already cited on published https://www.al-taswia.com pages'). This distinguishes it from get_article and search_articles, which deal with article content rather than legislation citations, though the description never names those siblings to make the boundary explicit.

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?

Provides explicit input guidance ('Send a topic, not client data') and a hard exclusion ('Personal-status topics are refused'), which tells the agent when the call will fail. It stops short of naming an alternative tool for the refused or non-matching cases.

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