bind_actor_property_to_sequence

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

Annotations already declare destructiveHint=true, readOnlyHint=false and idempotentHint=false, so the safety profile is covered by structured data. The description does not add the behavioral context an agent would want for a destructive mutation — whether existing bindings/tracks are preserved, whether re-running duplicates the track, or what permissions are required. It compensates somewhat by disclosing the return payload, which no structured field provides.

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?

Two front-loaded sentences state the action and its combined nature, followed by a compact return-shape block. Nothing is wasted, though the return block is dense and unlabeled relative to the prose.

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?

With no output schema present, the description carries the burden of describing the return value and does so thoroughly (binding_guid, track_class, section_class, binding_created, saved, save_error). The main gap is that it omits any prerequisite or failure precondition for a destructive combined operation.

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 description coverage is 100%, so all five parameters are already documented in the schema. The description only echoes the concepts ('typed property track', 'possessable') without adding format, constraint, or default semantics beyond what the schema states. Baseline 3 is appropriate.

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 precise verb+resource ('Bind an editor-world actor to a Level Sequence') plus the secondary action (add a typed property track), and labels itself a 'Combined bind+animate flow'. This lets an agent distinguish it from the separate bind_actor_to_sequence and add_property_track siblings without opening schemas. It stops short of naming those siblings explicitly, so it is clear but not maximally differentiated.

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?

The phrase 'Combined bind+animate flow' implies this is the one-shot alternative to the two-step bind/add-track path, which is useful implied guidance. However, there is no explicit when-to-use/when-not statement, no prerequisites (e.g., that the Level Sequence must already exist), and no call-out of the sibling tools it replaces.

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