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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered structurally. The description adds that results carry 'confidence and review status', which hints at potentially unevaluated or variable-reliability content, but it does not explain what those fields mean, how results are ranked, or how many are returned.

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, no filler, with the core purpose front-loaded and the return characteristics in a compact trailing clause. The parenthetical topic list is somewhat long but earns its place by scoping the lookup.

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, the description covers purpose, example inputs and the shape of the return well enough to call it correctly. It stops short of explaining result ordering, count, or how to interpret confidence/review status.

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 only one parameter and schema description coverage is 100%, so the baseline is 3. The description does supply additional example keywords beyond the schema's 'breach notification' and 'grievance', which helps an agent choose vocabulary, but it adds no syntax, granularity or matching-semantics detail.

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 names a specific verb and resource ('Look up DPDP Act sections and Rules by topic') and gives a concrete topic list spanning breach, consent, grievance, children, processor contract, erasure, safeguards and transfers. It is clearly distinguishable from the sibling tools dpdp_key_dates and dpdp_penalty_ceilings by domain, though it never explicitly contrasts itself with them.

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 topic examples – an agent can infer this is the tool for substantive obligations rather than dates or penalties. However, there is no explicit when-to-use/when-not statement, no guidance on what to do when a lookup returns nothing, and no named alternative tool.

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