Attach Custom Property

attach_custom_property

Attach a key/value pair to the active sequence and verify it lands in the XMP packet, reporting failure when it does not.

Instructions

Attach a custom property (key/value pair) to the active sequence and confirm it against the sequence project item's XMP packet. Reports failure when the property never lands in XMP.

TDQS

A3.9/5.0
Behavior4/5

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

Annotations already disclose that this is a non-readOnly, non-destructive, non-idempotent write operation. The description adds valuable postcondition behavior: it confirms the property in XMP and reports failure if it never lands there. It does not cover permissions or behavior when the property already exists.

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?

The description is two sentences, front-loaded with the action and target, and contains no filler. The second sentence adds the critical verification and failure behavior.

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

Completeness5/5

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

An output schema exists, so return values do not need explanation. The description covers the action, target, verification behavior, and failure mode, which is complete enough for this two-parameter write tool.

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 coverage is 100%, so both parameters are fully documented in the input schema. The description adds a 'key/value pair' framing but no additional format, validation, or usage details beyond the schema baseline.

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 states a specific verb (attach), resource (custom property key/value pair), target (active sequence), and verification against the XMP packet. It distinguishes the tool from generic metadata setters by emphasizing XMP confirmation and failure reporting.

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?

No explicit when-to-use, when-not-to-use, or alternative tools are mentioned. Sibling tools such as add_custom_metadata_field and set_xmp_metadata are not referenced, so the agent must infer when this tool is appropriate.

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