list_records

Read-only

List records in a collection for an account, with pagination. Provide the repo (handle or DID) and the collection NSID (e.g. app.bsky.feed.post).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description
`repo`	Yes	A handle or DID.
`limit`	No	Page size (1-100, default 50). A cursor in the response means more pages exist.
`cursor`	No	Pagination cursor from a previous page.
`collection`	Yes	Collection NSID, e.g. app.bsky.feed.post.

B3.2/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description's only added behavioral note is 'with pagination,' and even that is largely restated by the limit/cursor schema fields. It does not explain ordering, whether results can be empty, or rate limits.

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

Conciseness4/5

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

Two tight sentences with the purpose front-loaded and no filler. The second sentence mostly duplicates schema-level detail on repo and collection, which slightly dilutes the conciseness.

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

Completeness4/5

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

With an output schema present, return values need not be explained, and annotations cover the safety profile. The remaining gap is routing guidance relative to sibling list/get/count tools, but for a straightforward paginated list this is close to complete.

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%, so all four parameters (repo, collection, limit, cursor) are already documented in the schema. The description repeats the repo/collection semantics without adding format or edge-case detail, so the baseline 3 is appropriate.

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

Purpose4/5

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

States a specific verb (list) and resource (records in a collection for an account), plus a scope modifier (pagination). This is clearly distinguishable from singular get_record and count_records, but it never names or contrasts those siblings explicitly, so it stops short of a 5.

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

Usage Guidelines2/5

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

The description tells the caller how to fill in parameters ('Provide the repo... and the collection NSID') but gives no guidance on when to use this versus get_record, list_backlink_records, or count_records, and states no prerequisites or exclusions. Usage is only implied by the purpose sentence.

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