Read-only

Browse and filter enactments rather than searching their text: by jurisdiction (central or a state), issuing regulator, year and status. Use when the user wants to know WHAT exists in an area before asking what it says, or to confirm an Act's exact title before citing it. Cost: 1 credit.

Input Schema

Name	Required	Description	Default
`page`	No	1-based page number.
`sort`	No	Sort order. `popular` is DEPRECATED and behaves as `year_desc`: it ordered by a read counter held only in the retired store. Values: `year_desc`, `year_asc`, `title_asc`, `title_desc`, `popular`.	year_desc
`state`	No	Jurisdiction slug. `central` is a value here, for Union legislation. Live counts per jurisdiction are on GET /acts/coverage.
`search`	No	Keep only acts whose title contains this substring, matched case-insensitively. A title filter, not a search over the text: use POST /acts/search for that.
`status`	No	The publisher's lifecycle status for the act. Their claim, not our verdict: see GET /acts/{actId}/status. Values: `in_force`, `repealed`, `superseded`, `spent`.
`yearTo`	No	Latest year of enactment to include, inclusive.
`category`	No	Jurisdictional class of the instrument. `repealed` and `spent` are accepted for backward compatibility and resolve against the act's status instead. Values: `central`, `state`, `regulatory`, `repealed`, `spent`.
`pageSize`	No	Results per page (1-100).
`yearFrom`	No	Earliest year of enactment to include, inclusive. Matched against the publisher's own year field, which is occasionally corrupt, so there is no lower bound and a value below 1800 is a legitimate way to find those rows.
`department`	No	Accepts both regulator slugs such as `sebi` and `rbi` and free-text state department names such as `Law Department`. Values are not limited to a fixed enum or a uniform slug format.

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false and closed-world scope, so the safety profile is covered. The description adds genuinely useful context beyond them: the billing cost ('1 credit') and the pre-citation use case. It does not repeat annotation content, but it also doesn't add much else behavioral detail.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences plus a cost tag, with the browse-vs-search distinction front-loaded ahead of the use-case clause. No filler and nothing is buried.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained; the many filters are fully documented in the schema. Combined with clear usage routing and the credit disclosure, an agent has everything needed to call this correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the schema carries rich per-parameter notes (deprecated `popular`, corrupt year fields, `department` accepting mixed slug/free-text). The description only names the filter dimensions at a high level, adding little beyond what the schema already documents, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (browse/filter) and resource (enactments), and immediately scopes it against the sibling behavior: 'rather than searching their text.' It enumerates the filter axes (jurisdiction, regulator, year, status), so an agent can distinguish it from search_acts without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit when-to-use condition ('user wants to know WHAT exists in an area before asking what it says, or to confirm an Act's exact title before citing it') and an explicit contrast/exclusion against text search. The routing decision is fully determined by the description.

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