layerfs_operator_store_overwritten

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful ordering (newest first) and hints at pagination, but does not explain what an 'overwritten' layer is, whether pagination has defaults, or what the result set contains.

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 single sentence is front-loaded and contains no filler. It is efficient, though its brevity contributes to the gaps in parameter and scope explanation.

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?

Given zero schema description coverage, three parameters, and no output schema, one terse sentence is not enough. An agent would not know what 'layer' identifies, how pagination defaults work, or exactly which layers are considered overwritten by a publication.

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 0%, so the description must carry parameter meaning, but it explains none of the three parameters. The required 'layer' parameter is never described, and pagePos/pageSize are only weakly implied by the word 'page'.

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 states a specific resource (layers overwritten by a publication) and an ordering (newest first), so an agent can tell roughly what it returns. However, it does not differentiate this tool from siblings such as layerfs_operator_store_commits or layerfs_operator_files_history, and 'page' is an unusual verb that leans on the tool name for meaning.

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?

There is no guidance on when to use this tool versus alternatives like store_commits, files_history, or workspace_overlay, and no prerequisites or exclusions are stated. The only usage signal is the implied listing/paging behavior.

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