history
Read-onlyIdempotent

Filter and retrieve change history across all entities, sorted newest first. Scope results by time, entity, project, or changeset.

Instructions

Filtered change history across all entities, newest first.

Combine since, entity_path, project, and changeset_id to scope the result. On unparseable since input the response is [{"error": "..."}] so the caller sees the problem.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sinceNoTime window — ISO 8601 datetime OR relative shorthand: '15m' (last 15 minutes), '24h' (last 24 hours), '7d' (last 7 days), '5mo' (last 5 months), '1y' (last year). 'm' means minutes; 'mo' or 'mon' means months. Unparseable values produce an error rather than silently returning empty results. Empty = all time.
entity_pathNoFilter to a specific entity or path prefix.
projectNoFilter to a specific project/repository.
changeset_idNoFilter to a specific changeset (feature/task group).
limitNoMaximum number of results.

Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds value by specifying the newest-first ordering and error handling for invalid 'since' values, which is beyond the annotations.

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?

The description is concise with three short sentences, front-loading the main purpose. It avoids fluff but could be slightly better structured with a clearer separation of usage and error details.

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 presence of an output schema, the description covers key aspects: filtering, ordering, and error behavior. It does not mention pagination or the 'limit' parameter explicitly, but these are in the schema.

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 coverage is 100% with good descriptions for each parameter. The description merely reiterates that parameters can be combined, adding no new semantic information beyond what the schema provides.

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?

The description states it provides 'filtered change history across all entities, newest first', which clearly identifies the purpose. However, it does not differentiate from sibling tools like 'log_change' or 'diff', missing a chance to clarify when to use this tool specifically.

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

Usage Guidelines3/5

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

The description explains how to combine parameters to scope results and notes error behavior for 'since', but it does not provide guidance on when to use this tool versus alternatives like 'blame' or 'diff'.

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