Snapshot

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

With no annotations provided, the description carries the behavioral burden. It explicitly states 'no modifica nada' (does not modify anything), which is the key safety trait for a backup operation, and notes the backup is date-stamped. It does not cover overwrite or storage behavior, but the essential non-destructive nature is clearly disclosed.

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 short sentence with a useful parenthetical guarantee. It is front-loaded, non-redundant, and every word earns its place.

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 single-parameter tool with an output schema, the core action and non-modification guarantee are covered. Missing are usage context, relation to sibling snapshot tools, and parameter format details, making it adequate but not fully complete.

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%, and the sole parameter 'proyecto' is undocumented in the schema. The description mentions 'del proyecto', indicating the parameter is the project to back up, but does not specify expected format, ID vs. name, or any constraints, leaving the agent with minimal guidance.

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 clear action ('Copia de seguridad' – backup) and resource ('del proyecto' – of the project), and adds that it is date-stamped. It does not explicitly name sibling alternatives, but the creation semantics distinguish it from listar_snapshots and restaurar_snapshot.

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?

No explicit when-to-use or alternatives are mentioned. The phrase 'no modifica nada' implies it is safe for creating checkpoints, and the backup action is implied, but there is no guidance on when to choose this over listar_snapshots or restaurar_snapshot.

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