Add Bookmark

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

The description reveals a key behavioral detail: the bookmark is created with an empty exploration state, requiring manual capture in Power BI Desktop. This adds value beyond the annotations (which only have openWorldHint=false). For a creation tool, it offers reasonable transparency.

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

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

The description is exceptionally concise: two sentences with no unnecessary words. The purpose is stated first, followed by a key behavioral note. It is well-structured and efficient.

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

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

Given the tool's simplicity (create bookmark with two parameters) and no output schema, the description covers the core functionality and important caveat (empty state). It could mention the required report context but overall is adequate.

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

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

Schema description coverage is 100%, so the parameters are already well-documented in the schema. The description does not add any additional meaning or context about the parameters (displayName and activePageId), so it meets the baseline but does not exceed it.

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

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

The description clearly states the tool's purpose: 'Create a new bookmark.' It also adds context that the bookmark starts empty, which distinguishes it from other bookmark operations like renaming or deleting.

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

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

The description hints at usage by advising to use Power BI Desktop to capture the view state, but it does not explicitly state when to use this tool versus alternatives like pbir_list_bookmarks or pbir_rename_bookmark. No exclusion criteria or comparison to siblings is provided.

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