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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds value beyond them: it discloses the return shape (matching Q&A with canonical page URL and official verifying authority) and sets an expectation boundary ("General information, not legal advice") that an agent should not treat as authoritative legal output.

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?

Two sentences, zero waste: the first front-loads method plus scope, the second front-loads the return contract and the caveat. The topic enumeration is long but functions as the scope statement an agent needs to judge relevance.

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 supplies the return contract and the authority/URL fields, and it flags the non-advice boundary. It omits ranking or result-quality behavior, but nothing needed to call the tool correctly is missing.

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%, including examples for query, a bound for limit, and an enum for language, so the schema carries the load. The description adds nothing about parameter behavior (e.g. how keyword matching handles Arabic vs English), 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+resource ("Keyword search over CaseDaleel's published FAQ") and enumerates the topical scope (salary/gratuity, rent/eviction, cheques/debt, family, hiring a lawyer, platform), which no sibling covers. An agent can tell this apart from get_guide/list_guides/about_casedaleel without opening a schema.

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 topical scope and by the disclaimer that this is general information, not legal advice, but there is no explicit when-to-use/when-not or pointer to a sibling (e.g. get_guide for a structured deep dive). Adequate but leaves routing to inference.

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