layerfs_branch_publish

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

Annotations already declare destructiveHint=true, openWorldHint=true, idempotentHint=false, and readOnlyHint=false, so the agent knows this is a destructive non-idempotent write. The description adds useful context that the result is a new immutable layer, but it does not explain irreversibility, effects on existing main history, or permission requirements.

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 front-loaded sentence with no redundant text. Every phrase contributes directly to identifying the operation and its optional commit scope.

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 mutation with two parameters and no output schema, the description is too terse. It covers the core action but omits important context such as what publishing an unspecified commit means, what happens to existing main, and whether the operation can be undone.

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. It mentions branch and that commit is optional, but provides no format, identifier, defaulting, or semantic detail beyond the parameter names.

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 verb and resource: publish a branch, optionally a specific commit, to main. It also clarifies the output as a new immutable layer. It does not differentiate this operation from siblings such as layerfs_branch_merge or layerfs_workspace_commit.

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?

It implies the tool is for publishing a branch to main, but gives no explicit when-to-use guidance, prerequisites, or when-not conditions. It does not mention alternatives such as merge or workspace commit, leaving the agent to infer selection.

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