undo document changes

native.undo_document_changes

DestructiveIdempotent

Undo these exact applied changes. Disjoint later edits survive; overlapping newer edits return a conflict. Only undo when requested.

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
`work_id`	Yes
`arguments`	Yes
`read_skills`	Yes	Exact required native skills and their dependencies, copied from the accepted session bootstrap's skills array. Include only entries in that array. General mcp.* guides and native.{studio}.instructions are guidance, not native skill proofs.
`request_key`	Yes
`publication_proposal_id`	No	For native Social scheduling, the exact server-approved publication proposal. This identifier cannot confer approval by itself.
`expected_catalog_version`	Yes	For a new session, read a studios/{studio}/native/{pack} child toolset and copy invocation.catalog_version from a native tool descriptor. Do not use the top-level library version. For calls in an existing session, use that session proposal's catalog_version.

A3.7/5.0

Behavior4/5

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds genuinely non-redundant semantics: disjoint later edits survive while overlapping newer edits produce a conflict, which tells the agent about partial-success and failure modes not visible in annotations or schema.

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?

Three short sentences, no redundancy, with the core action front-loaded and the conflict behavior following immediately. Every sentence carries operational information.

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

Completeness3/5

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 no explanation, and the conflict/partial-survival rules are a valuable addition. Still missing for a destructive, multi-required-parameter tool is where change_ids come from and what happens on failure mid-batch, leaving the agent to infer prerequisites from 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 description coverage is 50%, and the description only implies that change_ids identifies "these exact applied changes." It adds nothing about document_id, expected_catalog_version, read_skills, or request_key, so it neither compensates for the gap nor overrides the schema baseline.

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 a specific verb and resource ("Undo these exact applied changes"), scoping the operation to a previously applied change set rather than arbitrary document edits. It is distinguishable from apply_document_edits and mark_document_changes_read by the notion of reversal, though it never names a sibling explicitly.

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?

"Only undo when requested" gives a gating constraint, which is real when-to-use guidance. However, it does not say what to do instead when an undo is not requested, nor how to choose between this tool and apply_document_edits or read_document_changes.

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