getRevisions

Read-only

Audit repository changes by retrieving paginated commit revisions with author, timestamp, and message. Filter with Lucene queries to pinpoint specific revisions.

Instructions

Returns repository revisions (commits) with author, timestamp, and commit message, paginated and filterable with query. Use it to audit recent changes across the repository; for one known revision number use getRevision. Cardinality: targets the full collection or a batch. For a single item by ID, use getRevision instead.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sortNoComma-separated list of fields to sort by, in priority order; prefix a field with `-` for descending order (e.g. `-updated,title`).
queryNoPolarion Lucene-style query string to filter results: field:value clauses combined with AND/OR, phrases in quotes. Exact supported field names depend on the resource type being queried.
fieldsNoSparse fieldset selector: an object keyed by resource type (e.g. `workitems`) whose value is a comma-separated list of attribute names to return (e.g. `id,title,status`), reducing payload size. Omit to return the default field set.
includeNoComma-separated list of related resource types to embed in the response (e.g. `author,attachments`) so they don't require a separate follow-up call. Omit to return only the primary resource.
page_size_NoMaximum number of items to return in this page (e.g. `100`). Use together with `page[number]` to paginate through a large result set.
page_number_No1-based page number to fetch when the result set is paginated (e.g. `2` for the second page). Combine with `page[size]`; omit to fetch the first page.

  4. First observedv1.0.0

TDQS

A4/5.0
Behavior3/5

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

Annotations already declare `readOnlyHint` and `openWorldHint`, covering the safety profile. The description adds useful behavioral context by noting pagination, query filtering, and collection/batch cardinality, but it doesn't go beyond this into side effects, permissions, or response behavior; this is adequate given the read-only annotation.

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

Conciseness3/5

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

The definition is front-loaded with the core behavior and usage guidance, but it repeats the 'use `getRevision` instead' instruction twice ('for one known revision number' and 'for a single item by ID'). Tightening this redundancy would make every sentence necessary.

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?

Given the rich parameter schema, read-only annotation, and presence of an output schema, the description supplies the remaining context: collection scope, cardinality, and the exact sibling for single-item needs. A small gap is that 'repository revisions' is not tied to a concrete endpoint or default ordering, but no crucial invocation detail is missing.

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 the parameter list already carries full meaning. The description only names `query` in passing and does not add semantic detail beyond the schema, 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?

The description opens with a specific verb and resource: 'Returns repository revisions (commits) with author, timestamp, and commit message', and it explicitly separates collection behavior from the single-item sibling `getRevision`. This leaves no ambiguity about what the tool does or which tool to pick.

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?

It states the intended use case ('Use it to audit recent changes across the repository') and the exclusion ('for one known revision number use `getRevision`'). It also explains cardinality as collection or batch, which guides selection.

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