mergeDocumentFromMaster

Destructive

Merges Master Work Item changes into a specified Branched Document; use dry_run to validate arguments and preview the irreversible request before sending it to Polarion.

Instructions

Merges Master Work Item changes to the specified Branched Document. Effect: irreversible — data removed or overwritten by this call cannot be recovered through the API. Tip: set dry_run: true first to validate the arguments and preview the exact request without sending it to Polarion. The executor returns this preview as normal text, and as structured content when the tool declares an output schema.

Input Schema

NameRequiredDescriptionDefault
dry_runNoIf true, validates the request and returns the exact request that would be sent to Polarion — with the Authorization header redacted and any binary payload summarized by byte length — without actually sending it.
spaceIdYesThe Document Space ID (a folder-like grouping of documents/pages within a project). Use `_default` (no quotes) to address the project's default space.
projectIdYesThe Polarion project ID (its URL segment, e.g. `myproject`), case-sensitive. Required to scope the request to one project. If the ID is unknown, ask the user; getProjects lists IDs only with global read access.
requestBodyNoMerge Document parameters.
documentNameYesThe Branch Document Name.

TDQS

A4.3/5.0
Behavior5/5

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

Beyond the annotations, the description explicitly warns that the operation is irreversible and that overwritten or removed data cannot be recovered through the API. It also explains the dry-run preview behavior, adding meaningful safety context for a destructive, non-idempotent tool.

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?

The description is three tight sentences: purpose first, then the destructive-effect warning, then the safe-preview tip. Every sentence adds actionable information with no repetition or filler.

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?

For a destructive mutation with full schema coverage, annotations, and an output schema, it covers the critical risks and preview path. It could go slightly further by mentioning prerequisites or exactly what the merge changes, but nothing essential for safe invocation is missing.

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

Parameters4/5

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

The schema already documents all five parameters at full coverage, establishing a baseline of 3. The description adds value by explaining that dry_run previews the exact request without sending it and describes how that preview is returned, though it does not elaborate on requestBody fields such as userFilter or createBaseline.

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: merging Master Work Item changes into a specified Branched Document. The direction is clear, but it does not explicitly name or differentiate itself from the sibling mergeDocumentToMaster, which could otherwise be confused with it.

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

Usage Guidelines4/5

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

It gives clear procedural guidance to set dry_run: true first for validation and preview. It does not state when to prefer mergeDocumentToMaster or when-not-to-use, so it lacks explicit alternative routing.

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