Commit projects

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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true), so the bar is lowered. The description usefully adds the concurrency trait ('in parallel'), but for a bulk mutation it omits critical behavior: whether a failure in one repo aborts the rest, and whether it is transactional across projects.

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?

A single front-loaded sentence with zero filler, so nothing is wasted. It is arguably undersized for a parallel bulk mutation with two undocumented parameters, which slightly limits 'appropriately sized'.

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, 0% schema coverage, and no annotations on failure semantics, the description leaves key questions open: which projects are affected when project_dirs is null, and what happens on partial failure. For a write tool operating on many repositories, this is inadequate.

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 compensate and it largely does not. It never explains 'message' or 'project_dirs', notably leaving the default-null semantics (presumably all discovered projects) undefined even though the phrase 'multiple projects' hints at the parameter.

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 specific verb (commit), the target (staged changes), and the scope (multiple projects, in parallel), which distinguishes it from the singular repository_manager_commit_project sibling. It does not, however, explicitly name or contrast with that sibling, so the differentiation must be inferred from 'multiple projects'.

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 choose this bulk tool over the single-project repository_manager_commit_project, nor any prerequisite such as changes needing to be staged first. The reader must infer the pre-commit workflow entirely.

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