execute_command

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

With no annotations, the description carries the full burden for behavioral disclosure. It adds useful context that commands execute in a specific order and that note-operating commands require an open note. However, it does not disclose what happens on failure (e.g., whether execution aborts), whether there are side effects, or any permission requirements. This is a moderate level of 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 two sentences, each serving a distinct purpose: the first states the tool's action and sequencing, the second gives a critical usage tip. It is concise, front-loaded with the verb, and contains no filler 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?

Given there is no output schema and no annotations, the description should explain return behavior and error handling to fully equip an agent. It does not mention what the tool returns (success/failure, results), what happens if a command fails, or whether it requires Obsidian to be running. For a tool that executes potentially side-effectful commands, this is a significant gap.

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 100%: both vaultId and commands have descriptions. The tool description does not add parameter-level meaning beyond the schema; it merely reiterates that commands are Obsidian commands. Therefore, the baseline of 3 applies, as the schema already documents parameters adequately.

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 'Execute' with resource 'Obsidian commands' and adds 'in order' to clarify sequencing. This clearly distinguishes it from sibling tools like list_commands, which only lists commands, and content-modification tools like put_content or append_content.

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 provides a clear usage condition: 'For commands that operate on notes, open a note first.' This indicates when a prerequisite step is needed and implies that executing such commands without an open note may not work. However, it does not explicitly compare with alternatives, such as using list_commands to discover command IDs, so it stops short of a full when-to-use vs alternatives explanation.

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