material.texture.clear

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

Annotations already mark the operation as destructive and idempotent, so the description's added value is the rollback-restore behavior and the scoping to an 'exact inspected' link set rather than broad channel clearing. This provides meaningful context beyond the structured annotation fields. No contradiction with annotations exists.

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 a single compact sentence with no redundant wording, and the main action is front-loaded. Its terseness is a minor weakness because important behavioral and parameter context is omitted, but as a concise sentence it is well-formed.

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 destructive, transactional, 11-parameter operation with optimistic-concurrency expected values, the description is far too incomplete. It does not explain how to obtain the expected identities, that the tool must run within an active transaction, or what 'exact inspected' requires in practice. The presence of an output schema does not compensate for missing invocation guidance.

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?

With schema description coverage at 0%, the description carries the full burden of explaining 11 parameters, but it only hints at 'channel' and 'incoming link set' (expected_link_identities). It does not explain transaction_id, expected_material_identity, expected_node_identity, expected_material_users, expected_scene_generation, idempotency_key, or allow_shared, which are all essential to calling the tool correctly.

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?

The description names a concrete action ('clear') on a specific resource ('incoming link set' on a 'Principled semantic channel'), and the sibling tool list includes material.texture.bind, making the intended operation distinguishable. It is clear enough despite depending on domain jargon like 'Principled semantic channel' and 'structural transaction.'

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 description gives no explicit guidance on when to use this tool versus alternatives such as material.set_input or material.texture.bind. The rollback mention implies a transactional context, but it never states 'use inside a transaction' or identifies when this tool should not be used.

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