commit_backup

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

With no annotations provided, the description fully discloses behavioral traits: network access, reliance on local git credentials, idempotency with skipped commits, error conditions (no backup repo, push failure), and return value structure. This is exemplary transparency.

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 dense but every sentence contributes critical information about side effects, auth, idempotency, error behavior, and return values. No filler or redundancy.

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 the tool's complexity (network, git, auth, errors, return value) and absence of an output schema, the description covers all essential aspects: what happens, what is returned, when it throws, and when to invoke it. It is fully self-sufficient.

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?

The only parameter is project_id, whose schema description is minimal ('Project ID'). The description adds context by referring to 'the project's KB data,' implying what the ID is used for. Since schema coverage is 100%, this is adequate but not enhanced beyond baseline.

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 clearly states the tool's purpose: syncing KB data to a git backup directory, creating a commit, and pushing to origin. It uses specific verbs and resources, and it is easily distinguished from siblings like file management or journal tools.

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 explicitly states when to use the tool: 'Use after a batch of KB writes to get changes off-machine.' It does not mention alternatives or exclusions, but the guidance is clear enough to place it above the baseline.

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