timeline

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

With no annotations, the description carries the full behavioral burden, and it does add one useful detail: start/end are ISO timestamps interpreted in the image timezone. However, it omits whether the tool is read-only, how results are ordered or paginated, and what the cryptic kinds letters actually mean, leaving a mutation-free forensic read largely undescribed.

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 dense sentence with the core concept front-loaded and no filler. It is terse to the point of omitting needed detail, but nothing in it is wasted.

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 an 8-parameter forensic tool with no annotations, no output schema, and 0% schema coverage, the description is too thin. It leaves the required image argument, part/limit/include_deleted semantics, and the meaning of the kinds codes unexplained.

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 for all 8 parameters, but it only touches start, end, path_regex, and kinds. The required image parameter, plus part, limit, and include_deleted, receive no explanation anywhere, and the kinds values 'm a c b' are listed without defining the MACB semantics.

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 and resource: a file-system timeline built from a directory walk, scoped by start/end. An agent can tell it produces a chronological view rather than a flat listing, though it never explicitly contrasts itself with close siblings like find or ls.

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 guidance is given, and no alternative is named. It is unclear when an agent should pick timeline over find, ls, stat, or grep_files for filesystem exploration, leaving selection entirely to inference.

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