Add recent file

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

Annotations already declare readOnlyHint=false and idempotentHint=false, so the mutation and non-idempotent nature are known. The description adds that the effect is appending to a per-host recent-files list, which is useful but minimal. It does not disclose behavior on duplicates, file existence requirements, or any open-world side effects despite openWorldHint=true, leaving some behavioral uncertainty.

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 short but includes a redundant first sentence 'Add recent file' that merely restates the title. The second sentence contains the substantive content. The redundancy wastes space and could be removed without loss.

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 3-parameter tool with no output schema and no parameter descriptions, the description is too thin. It does not clarify whether both name and path are needed, whether recent files are per-host, or any constraints on hostId or file paths. An agent cannot reliably construct a correct call without additional information.

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%, so the description must compensate. It mentions 'file' and 'host' but does not map these to the schema properties (name, path, hostId), nor does it indicate requiredness, formats, or semantics. An agent cannot infer that name/path identify the file and hostId identifies the host with confidence, leaving significant ambiguity.

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 clearly states a specific verb ('Adds') and resource ('a file to the list of recent files for a host'), which matches the tool name and distinguishes it from sibling tools like termix_hosts_add_pinned_file and termix_hosts_add_shortcut by naming the 'recent files' list. The first sentence is redundant with the title, but the second sentence provides sufficient purpose clarity.

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 guidance is given on when to use this tool versus alternatives. It does not mention conditions such as 'use after opening a file' or contrast with add_pinned_file or add_shortcut. With several sibling tools sharing the 'add' prefix, the lack of usage context is a meaningful gap.

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