ketan_snapshot

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly states the tool is atomic, creates a checkpoint, and returns a checkpoint ID, effectively setting expectations for behavior and output.

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 four sentences, front-loaded with the core action, and every sentence earns its place by adding either purpose, usage guidance, or return value. There is no fluff or repetition.

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 zero-parameter tool with an output schema, the description provides all essential context: what it does, when to use it, and what it returns. It also references ketan_rollback, linking to sibling tools for a complete workflow.

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 tool has zero parameters, and the schema coverage is 100% (empty), so the baseline is 4. The description doesn't add parameter-level detail, but that's unnecessary here; it does mention the return value, which is helpful.

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 uses a specific verb ('Take') and resource ('atomic filesystem snapshot of the entire workspace'), making the tool's function immediately clear. It also distinguishes itself from sibling tools like ketan_rollback and ketan_write_file_safe by focusing on snapshot creation.

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: 'Always call this before a risky sequence of operations.' It also frames the tool as a safeguard, referencing rollback as a complementary action, which provides clear contextual guidance.

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