unpin

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

With no annotations provided, the description carries the full burden. It discloses idempotency, replica queueing behavior, the refusal condition, and the possible reply strings. This is exceptional behavioral transparency for a mutating tool.

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 dense but every sentence conveys necessary information: purpose, alternative, edge cases, and response semantics. Slightly long and the 'Code lane:' opener is opaque, but otherwise well-structured and front-loaded.

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?

For a one-parameter tool with no output schema and meaningful edge cases, the description covers operation semantics, alternatives, idempotency, replica behavior, refusal conditions, and expected replies. Nothing essential to invoking it correctly is missing.

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 coverage is 100%, and the schema already documents the sole 'id' parameter as 'The id to unpin (remove the Always binding from it)'. The description adds context like 'existing item' and idempotency, but does not substantially enhance the parameter's meaning beyond the schema baseline.

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?

States a specific verb ('removes') and resource ('the Always binding from an existing item'), and explicitly distinguishes itself from revise. This gives an agent a clear, differentiated understanding of the operation.

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?

Explicitly says to use revise when anything besides the binding needs to change, and explains when unpin is refused. This provides concrete selection criteria and a conditional path for using it correctly.

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