list_commands

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

With no annotations and no output schema, the description carries the full behavioral burden. The Windows qualifier hints at a platform constraint, but nothing is said about what is returned (names only? IDs needed for execute_command?), the required Obsidian/runtime state, or why the platform matters.

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 no filler. Appropriate length for a zero-param listing tool, though the trailing platform qualifier is slightly odd.

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 simple no-argument listing tool this is borderline adequate, but with no output schema and no annotations the agent is left guessing the return shape and how the results link to execute_command or other siblings.

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?

Zero parameters, so the baseline is 4. There is no parameter syntax to add beyond what the empty schema already conveys.

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 ('Lista') and resource ('todos os comandos da paleta do Obsidian'), so the agent knows it enumerates available commands. It does not explicitly contrast with the obvious sibling execute_command, though list-vs-execute is inferable.

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 when-to-use statement and no mention of the natural pairing with execute_command (discover, then run). The agent must infer that this is a discovery step from context alone.

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