Unfollow an account

unfollow
Idempotent

Stop following a Bluesky account by handle. Finds your follow record from profile viewer state, so only the handle is needed.

Instructions

Stop following an account. Finds your own follow record from the profile's viewer state, so you only need the handle.

TDQS

A4/5.0
Behavior4/5

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

Annotations declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, covering the safety profile. The description adds a useful behavioral detail: it locates the user's own follow record from the profile's viewer state, reducing the required input to just the handle.

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?

Two tight sentences, front-loaded with the action and followed by a concise implementation note. No wasted words.

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 simple mutation tool with full schema coverage and safety annotations, the definition is mostly complete. The mechanism note is helpful, though it omits what happens if you are not following (partially covered by idempotentHint) and does not mention the optional account parameter.

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 100%, so the schema already documents both parameters. The description's note that you 'only need the handle' is a mild usability clarification but does not add new semantic meaning beyond what the schema provides.

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?

States a specific verb and resource ('Stop following an account') and adds mechanism detail about finding the follow record from viewer state. The tool's identity is immediately clear and distinct from mute/block siblings.

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?

Implies usage through the action description, but does not explicitly say when to use this versus alternatives like mute_account or block_account. No exclusions or prerequisites are stated.

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