create_bookmark

Save any link as a Raindrop bookmark with automatic metadata parsing. Add notes, tags, a custom title, cover, excerpt, importance flag, or assign to a collection as needed.

Instructions

Create a bookmark; link is required and metadata parsing is enabled.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A3.5/5.0

Behavior4/5

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

Annotations already establish that this is a non-read-only, non-destructive mutation. The description adds a useful behavioral detail beyond annotations: metadata parsing is enabled, meaning the tool will parse metadata from the provided link. This does not contradict 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 a single compact sentence with the core purpose front-loaded and no filler words. It is appropriately concise, though the brevity contributes to the parameter-semantics gaps.

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?

The description is minimally sufficient for a basic call because it states link is required and metadata parsing is enabled, while the output schema and annotations cover return shape and safety. However, with nine parameters and no explanations for most of them, the description is not complete enough for confident, richer usage.

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

Parameters2/5

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

Schema description coverage is 0% and the description only addresses link and parse_metadata, both of which are already visible in the schema. The seven optional parameters (note, tags, cover, title, excerpt, important, collection_id) receive no semantic explanation, so the description fails to compensate for the low schema coverage.

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 uses a specific verb and resource ('Create a bookmark') that clearly separates it from the sibling operations list_collections, search_bookmarks, get_bookmark, and update_bookmark. It also adds the scoping constraints that link is required and metadata parsing is enabled.

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

Usage Guidelines2/5

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

There is no explicit guidance about when to use create_bookmark versus update_bookmark, or when not to use it. The only usage clue is implied by the verb 'Create' and the statement that link is required; no alternatives or exclusions are mentioned.

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