instagram_unpin_post

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

No annotations provided. Description states the action but does not disclose any additional behavioral traits like verification requirements or error states. Acceptable for a simple action.

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?

Single sentence, efficient, and directly states the purpose. No wasted words.

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?

Tool is simple with one parameter and output schema exists, but parameter semantics are incomplete. Overall adequate but not excellent.

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?

The single parameter 'media_id_or_url' has no description in schema (0% coverage) and the description does not clarify expected format (ID vs URL). This is a significant gap for correct invocation.

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?

Description uses clear verb 'Remove' and specific resource 'pinned post' with context 'from the top of your profile grid'. It clearly distinguishes from 'instagram_pin_post'.

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?

Implicitly clear when to use: when you want to remove a pinned post. No explicit when-not or alternatives, but given simplicity, it's sufficient.

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