Set Permissions

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

No annotations are supplied, so the description carries the full behavioral burden, yet it discloses nothing about privilege requirements, irreversibility, or the risk of recursively changing permissions on a directory tree. The only behavioral hint is the word 'chmod/chown' itself, which implies mutation but says nothing about safety or side effects.

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?

It is short and front-loaded, but this is under-specification rather than conciseness. A four-word fragment cannot earn its place as the sole guidance for a six-parameter destructive operation.

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 return values need not be described, but for a mutation tool with zero annotations, 50% parameter coverage, and sudo/recursive options, the definition is far too thin. It omits privilege escalation behavior, recursion risk, and format expectations for owner/group.

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 coverage is 50%: mode, sudo, and recursive have inline descriptions, but path, owner, and group are undocumented in both schema and description. The four-word description adds essentially no semantics beyond the command names, leaving half the parameters without any explanation of expected format.

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 names two concrete operations (chmod/chown) and a target (a path), which lets an agent distinguish it from clipboard, window, or dconf siblings. However, it never spells out that this changes filesystem ownership/permissions, and the shorthand assumes the reader knows the Unix commands.

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 prerequisites, and no mention of alternatives or when-not to use it. The agent must infer entirely from the name that this is for permission changes rather than, say, file copying.

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