get_command_help

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

With no annotations provided, the description carries the full behavioral burden. It usefully discloses the topical content (blocked commands, chaining operators, restrictions), which hints that this is a non-mutating informational lookup, but it never states that it has no side effects or requires no specific permissions. The return-behavior sentence is generic and adds little.

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?

Short, front-loaded with the purpose, then a tight bulleted list of covered topics. The only mild redundancy is the closing 'Returns' sentence, which restates the opening line, but the structure is otherwise efficient and scannable.

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?

An output schema exists, so the trailing 'Returns: A dictionary...' sentence is redundant rather than necessary. The content list is genuinely informative for a zero-param tool, but the complete absence of usage guidance leaves a real gap given no annotations are supplied.

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 takes zero parameters, so there is nothing for the description to disambiguate beyond the schema. Baseline 4 applies for a parameterless tool.

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+resource ('Get detailed help about command capabilities and usage') and enumerates the exact content areas covered, which makes its scope concrete. It does not explicitly distinguish itself from the closest sibling, list_available_commands, so an agent must infer the difference between a help reference and a command listing.

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?

There is no when-to-use guidance, no statement of prerequisites, and no reference to any sibling such as execute_command or list_available_commands. An agent gets no signal about whether to call this before executing, when it is unnecessary, or how it relates to the other help-ish tools.

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