Ask question

ask

Files a question to registry participants so they see it in their feed or inbox; it remains open until an answer is filed, and blocking questions pause task progress.

Instructions

Files a question to registry participants. The tracker delivers nothing: an addressee sees the question when reading the feed or their inbox.

A question stays open until an answer with its number is filed in the same task; it counts toward open_questions, and with blocking toward open_blocking_questions.

A blocking question is the carrier of a wait on its addressee or on an event outside the tracker that the addressee learns of; any participant files the answer. The answer to the last such question makes a task in open a candidate again, with no status move.

What the cases of the parent, its ancestors and sibling tasks already record is readable through get_task and read_entries, without a question.

Input Schema

TableJSON Schema

Name	Required	Description
`key`	Yes	Task key `PROJECT-N`, case-insensitive; a previous key of a moved task addresses it as well. An unknown key is refused with `task_not_found`
`body`	No	Entry body in markdown, stored and returned as is. It holds what a successor needs to continue; file contents and long outputs stay outside it, represented by a pointer and the gist
`title`	Yes	Entry title: its line in the case index of `get_task`. It states what happened, not how
`blocking`	Yes	Whether work on the task can go on without the answer. `true` counts toward the `open_blocking_questions` feature, by which such tasks are selected, and refuses entry into `in_progress` with `task_has_open_blocking_questions` while the question is open; the tracker does nothing else with it
`addressees`	Yes	Names of participants from `list_participants`, at least one. A temporary agent has no registry entry and cannot be addressed. An unknown name is refused with `entry_fields_invalid`, `reason: unknown_participant`
`idempotency_key`	No	Retry key chosen by the caller, e.g. a UUID. A repeat with the same key and the same arguments returns the first result and creates nothing; the same key with other arguments is refused with `idempotency_key_reused`. A key is bound to the caller's token and kept for 24 hours

Output Schema

TableJSON Schema

Name	Required	Description
`no`	Yes	Entry number in the task's case; with the key it forms `TRK-42#12`
`seq`	Yes	Journal sequence number, usable as `after` of `wait_journal`
`title`	Yes	The title the tracker built, for entry types whose title is not sent (summary, answer, verdict, resolution, service entries); `null` when the caller sent the title
`author`	Yes
`task_key`	Yes
`created_at`	Yes

A3.6/5.0

Behavior4/5

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

Annotations already cover the mutating/non-idempotent/non-destructive profile, so the bar is lower. The description adds meaningful behavioral traits beyond annotations: the tracker delivers nothing (unusual semantics), open-question counting, the effect of blocking on in_progress entry, and the status behavior when the last blocking question is answered.

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

Conciseness3/5

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

It is front-loaded with the core action, but the body is unfocused and redundant: the delivery/waits/waiting behavior is explained in multiple sentences with some circular phrasing (e.g. 'carrier of a wait on its addressee'), and information spills into prose that could be tighter.

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?

The description covers the tool's unusual lifecycle semantics (open until answered, blocking semantics, effect of the last answer) and hints at reading records via get_task/read_entries. With a 6-param schema and output schema present, this is fairly complete, though the usage boundary against 'answer' and 'resolve' could be clearer.

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 description coverage is 100%, so the schema already documents all six parameters in detail. The description doesn't add parameter-level semantics beyond what the schema provides, so the baseline 3 is appropriate.

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

Purpose4/5

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

The description states a specific verb and resource: it files a question to registry participants and explains that the tracker delivers nothing, distinguishing it from a notify/message tool. It doesn't explicitly contrast with the sibling 'answer' tool, but the resource and action are clear.

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

Usage Guidelines3/5

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

Usage is implied but not framed with explicit when/when-not guidance or named alternatives. The final sentence implies that reading existing records uses get_task/read_entries rather than a question, but it's not framed as a routing rule for the agent.

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