kanban

The kanban worker owns one board file (/board.json) holding every ticket with its comments and activity timeline inline. Every ticket carries an internal uuid and a human key (KAN-7, case-insensitive); both work everywhere a ticket is addressed. Columns, priorities and the key prefix are configuration (kanban::config::info prints the live values), and the default board is backlog, todo, in_progress, in_review, done.

Tickets are never removed by an agent: a finished ticket is moved to in_review or done, and a human soft-deletes from the console's ticket screen (the row stays on disk with deleted_at set). Writes take an actor and comments an author; pass your own agent-profile id in both, because the comment filters below key on exactly that string. The worker also injects a board page and a ticket page into the console.

When to Use

• A feature is being planned, dispatched to other agent profiles, or reviewed, and the plan must outlive the chat session.
• You were dispatched onto a ticket and must claim it, report on it and hand it off where the reviewer will see it.
• You need to react to a human's or another agent's comment on one ticket without polling.
• The console should show a board or a ticket beside the conversation.

Boundaries

• Not a general task queue or a durable job store; use queue for work that must be executed, and the board for work that must be planned and reviewed.
• No author filter on kanban:change; use kanban:comment with exclude_author for a feedback loop that must not wake on your own posts.
• Deleting and restoring tickets is the human's action; agents move tickets.
• Agent profiles are resolved through iii-directory (with the configured agents folder as the fallback); this worker does not create profiles.

Functions

• kanban::config::info — resolved settings: board file path, columns, priorities, key prefix, agents folder.
• kanban::board::get — every column with its ticket summaries; statuses, updated_since, limit and compact keep the read small.
• kanban::ticket::create — create a ticket (title, description, status, priority, assignee, labels, actor).
• kanban::ticket::get — one ticket with comments and activity, by uuid or key.
• kanban::ticket::list — ticket summaries narrowed by column, assignee or updated_since; compact rows for catch-up reads.
• kanban::ticket::update — change title, description, status, priority, assignee or labels.
• kanban::ticket::move — move a ticket to a column and position (the board drag and drop).
• kanban::ticket::delete / kanban::ticket::restore — soft delete and undo; human actions.
• kanban::comment::create — comment or reply (parent_id); replies stay one level deep.
• kanban::comment::list — comments filtered by author, excluded author, root only, or since a timestamp.
• kanban::activity::list — the ticket's timeline, oldest first, optionally narrowed by type or time.
• kanban::agent::list — assignable agent profiles and their ids.

Reactive triggers

Register a kanban:comment trigger when a session or function should run every time someone comments on one ticket — the reviewer's answer after a hand-off, a human's reply, another agent's note — without re-reading the board.

Reach for it when:

• You reported on a ticket and moved it to in_review, and the rejection or acceptance must reach you after your turn ended.
• You dispatched a ticket to another profile and its report arrives as a comment.

If you only need the comment you just wrote, use the return value of kanban::comment::create; register a trigger only when a different author should wake you. kanban:change is the board-wide sibling: it fires on every event (ticket.created, ticket.updated, ticket.moved, ticket.deleted, ticket.restored, comment.created) with the whole ticket, filtered by ticket and event name only, and is the right primitive for keeping a view in sync or for a done-watch on ticket.moved.

How to bind

1. Register a handler, or omit function_id from an agent session to be woken.
2. Register the trigger:

engine::register_trigger {
  "trigger_type": "kanban:comment",
  "config": { "ticket_id": "KAN-7", "exclude_author": "<your profile id>", "ticket": "summary" },
  "once": false,
  "lifecycle": { "max_fires": 20, "expires_in_ms": 3600000 }
}

ticket_id is required and matches the uuid or the key; author, exclude_author and root_only narrow further. "ticket": "summary" on either trigger type delivers the board-card fields instead of the whole ticket with its thread — the right choice for an agent that re-reads the ticket on a wake. Mutations fire triggers; reads do not. The worker delivers only to bindings in its own in-process map, so pair a standing wake with a cron check-in over kanban::comment::list. For the payload shape call get function info on the trigger type.
