kaiten_update_time_log

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose one meaningful constraint ('author only'), but it does not explain whether omitted optional parameters leave existing values unchanged, whether the update is partial or full, or what happens after a successful update. For a mutating operation this is thin.

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 a single sentence with no filler words. It front-loads the action and resource, then adds the author-only permission caveat, which is directly useful for invocation decisions.

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?

All parameters are documented and the core intent is clear, making the tool minimally callable. However, with no annotations and no output schema, the agent is left guessing about update semantics such as partial updates, response behavior, and whether the author-only restriction refers to the authenticated caller.

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 input schema already provides descriptions for all six parameters, including constraints like min/max and format hints, so schema description coverage is 100%. The description adds no additional parameter-level meaning beyond identifying that the time log belongs to a card.

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 states a specific action ('Update') and a specific resource ('time log entry on a card'), and the '(author only)' qualifier adds useful scope. It is clearly distinguishable from sibling tools like kaiten_create_time_log and kaiten_delete_time_log.

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 no guidance on when to use this tool versus alternatives such as kaiten_create_time_log, kaiten_delete_time_log, or kaiten_list_card_time_logs. The only contextual hint is the author-only restriction, which is a permission constraint rather than usage guidance.

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