Update O!task Task

otask_update_task

Update an O!task task by providing only the fields to change. The tool fetches the current task, merges your changes, and submits the update.

Instructions

Update an existing O!task task. Sends POST /api/v1/ws/{ws_slug}/tasks/{task_slug}/update.

The O!task API requires a full task payload. This tool fetches the current task, merges your changes, then submits the update. Only pass fields you want to change.

Common updates:

  • board_column_id: move task to another column/status

  • name, description, end_at, priority_id

  • performers, tags, subtasks, files

  • comment: optional note recorded with the update

Args:

  • ws_slug, task_slug: UUIDs from panel.otask.ru

  • Any task fields to change (all optional except slugs)

Returns updated task summary on success.

Behavior4/5

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

Annotations indicate non-readOnly, non-idempotent, non-destructive. Description adds that it fetches current task, merges changes, and submits full payload, providing crucial behavioral context beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with bullet points for common updates and Args. No unnecessary sentences; every part adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Complex tool with 14 parameters, high schema coverage, no output schema. Description covers the merging process and return value ('returns updated task summary'), making it fairly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 93%, so baseline is 3. Description adds value by explaining common parameter usage (e.g., 'board_column_id: move task') but does not significantly extend beyond schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states 'Update an existing O!task task' with the HTTP method and endpoint. Distinguishes from sibling 'otask_get_task' by being an update operation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly advises 'Only pass fields you want to change' and lists common updates. While it doesn't mention when to use an alternative (e.g., create), the context is clear for update vs. read.

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