| description | Run the Agent Kanban task lifecycle: create, assign, monitor, and either
hand review to an active board maintainer or review and finish the task as
leader. Use only when the user explicitly asks for AK Task, Agent Kanban,
an AK task, or delegation through an AK board. Do not use for ordinary
feature implementation, bug fixing, or generic task creation.

ak-task — Task Lifecycle
Create a task, assign it, then monitor it to completion. Review ownership
depends on whether the selected board has an active maintainer.
Identity
This is a leader workflow.
If ak says no leader identity exists for the current runtime, create one first:
ak auth login --leader-agent --username <username> [--name <name>]
The leader chooses its own username and optional full name.
Unattended Execution Contract
Assume this workflow runs in two explicit modes:
- Before task creation: human-in-the-loop. Ask the user only during the initial clarification and task preview phase, before task creation is confirmed.
- After task creation: human-not-in-the-loop. Once the user confirms the task and it is created, do not stop to ask for permission, confirmation, or next steps unless the user interrupts you. Continue through the full work cycle and report the outcome. On a board with an active maintainer, monitor while the maintainer owns review and completion. Otherwise, review, reject, or merge as leader.
If execution hits a blocker after confirmation, use the available tools and repository context to resolve it. If the blocker cannot be resolved without external authorization or production mutation, fail fast with the exact blocker and the next required action instead of waiting in the middle of the workflow.
Workflow Checklist
Immediately after this skill is invoked, create and maintain an explicit task
plan/checklist in the agent UI. This checklist is a guardrail against attention
drift during clarification, preview, and execution handoff.
The checklist must include the full lifecycle:
- Resolve task scope and target context.
- Investigate code, repo, board, labels, workers, and related tasks.
- Preview the exact task and get human confirmation.
- Create labels/workers if needed, then create and assign the task.
- Switch to human-not-in-the-loop execution.
- Monitor the task according to the selected board's review owner.
- If a maintainer is active, wait for maintainer-owned review and completion.
- Otherwise review the PR: CI, code, functional acceptance, and notes.
- In leader-review mode, reject or merge and repeat until the task is done.
- Report final outcome.
Keep this checklist current:
- Mark exactly one active step as in progress.
- Update statuses at every phase transition.
- When review ownership makes a conditional checklist item inapplicable, mark
that item completed as not applicable instead of leaving it pending.
- After
ak create task, explicitly mark planning/creation complete and mark
monitoring/completion as in progress before any final user-facing summary.
- Do not send a final answer while any post-creation execution step remains
pending, unless the user explicitly says to stop, cancel, abort, or only
create the task.
- If context becomes long or the user interrupts, re-read the checklist before
deciding the next action.
Input
Parse the user's input:
- What — feature description or bug report (required)
- Board — which board (if not specified, use the first board)
- Labels — use board-level taxonomy for stable filtering; create only reusable missing labels before task creation
Phase 1: Create & Assign
Step 1: Context
Before choosing or creating workers, read references/runtime-delegation.md. Before creating any worker, also read references/agent-creation.md and follow its Worker Profile Preview.
ak get board
ak get maintainer --board <board-id> -o json
ak get label --board <board>
ak get agent -o json
ak get model --runtime <name>
ak get repo
If there's only one board, use it. Otherwise ask which board.
Review Ownership
Resolve review ownership immediately after selecting the board and before
previewing or creating the task:
ak get maintainer --board <board-id> -o json
- If the returned array contains a maintainer whose
status is active, use
maintainer-review mode. Record its id in the task preview. The leader
creates, assigns, and monitors the task, but does not review the PR, reject
the task, post verification evidence, merge the PR, or complete the task.
- If none of the returned maintainers has
status: active—including an empty
array or paused maintainer records—use leader-review mode and follow the
original review workflow in this skill.
- Do not use
heartbeat_enabled to choose the mode. A maintainer can remain
active for event-driven review while scheduled heartbeats are disabled.
- Re-run the command before taking action on a task in
in_review. Switch to
leader-review mode only when no returned maintainer is active. If any
maintainer is active, remain in or switch to maintainer-review mode and
record an active maintainer id.
The CLI already exposes the required board-level check. Do not infer maintainer
state from agents, taints, task assignment, or heartbeat history.
Step 2: Investigate
Before creating the task, understand what's involved:
- Read CONTRIBUTING.md in the target repo to understand contribution requirements
- Read relevant source files to understand current implementation
- Identify which files need to change
- Check for existing related tasks:
ak get task --board <board-id>
Step 3: Confirm with User
Use AskUserQuestion to interactively resolve any uncertainties before creating the task. For each ambiguous point, present options for the user to choose from:
- Scope unclear — present 2-3 scope interpretations as options, each with a preview showing what files/changes are involved
- Multiple approaches — present implementation strategies as options with trade-off descriptions
- Labels/agent/runtime/repo ambiguous — present choices when there are multiple candidates
- Dependencies uncertain — present options about whether to depend on or parallelize with related tasks
Label Selection
Labels are board-level taxonomy, not free-form task notes. Use them only for stable filtering dimensions that will remain useful across tasks.
Before previewing the task:
- Run
ak get label --board <board-id> and reuse existing labels whenever possible.
- Choose at most a small set of labels, usually one version label plus one or two stable area/type labels.
- Create a missing label only if it will be reused beyond this task; otherwise put that detail in
## Spec.
- If label choice is ambiguous, ask during the initial clarification phase.
Recommended categories:
- Version —
vX.Y, for example v1.4; avoid patch versions or suffixes unless the board already uses that granularity.
- Area — stable implementation area such as
frontend, backend, api, database, cli, infra, docs, ui, security, or test.
- Type — optional when useful for filtering, such as
feature, bug, or refactor.
Avoid labels for temporary process state, runtime/provider choice, tools, libraries, branches, files, or one-off implementation details. Examples that usually belong in the task description instead of labels: blocked, testing, needs-review, codex, copilot, gemini, github, cloudflare, tailwind, sqlite, prompt-fix, and file names.
When labels overlap, prefer the canonical stable form: infra over infrastructure, bug over bugfix, database over db, and frontend for UI implementation unless the task is specifically visual polish.
Create missing reusable labels before task creation:
ak create label --board <board-id> --name v1.4 --color "#22C55E" --description "Version 1.4"
ak create label --board <board-id> --name backend --color "#38BDF8" --description "Backend/API work"
ak create label --board <board-id> --name bug --color "#F87171" --description "Bug fix"
Useful color defaults:
- Version:
#22C55E
- Frontend/UI:
#A78BFA
- Backend/API/database:
#38BDF8
- CLI/runtime:
#22D3EE
- Bug/security:
#F87171
- Infra/deploy:
#F59E0B
- Docs/refactor/general:
#71717A
Hard Stop: Agent Runtime Selection
Before creating workers or tasks, determine the worker runtime.
- If the user specified a runtime, assign only to a worker whose
runtime matches it and whose status.schedulable is true.
- If the user specified a runtime but that runtime is not schedulable, stop before worker or task creation and ask the user to choose an available runtime.
- If no matching available worker exists for the specified schedulable runtime, create a worker on that runtime before task creation using
references/agent-creation.md.
- If the user did not specify runtime and multiple available runtimes are reasonable for the task, ask the user to choose the runtime before creating workers or tasks.
- Never silently default to the leader's own runtime.
- Before choosing a non-default model for a new worker, run
ak get model --runtime <runtime> -o json and use a provider-reported model ID.
Keep iterating — each answer may reveal new questions. Only proceed to create when all points are resolved and the user has confirmed the final task spec.
If nothing is ambiguous (simple, clear-cut request), skip straight to the task preview below.
Structured Questions in Codex
Use the runtime's structured question tool during the pre-task-creation phase:
- In Claude-style runtimes, use
AskUserQuestion.
- In Codex, use
request_user_input.
For Codex Default mode, verify the feature flag before relying on interactive prompts:
codex features list | rg default_mode_request_user_input
Expected:
default_mode_request_user_input under development true
If it is not enabled, tell the user to enable the feature flag themselves and
restart Codex before continuing:
codex features enable default_mode_request_user_input
Do not run this command for the user. The current Codex session will not gain the
tool after an automatic config change; the user must enable it and reopen Codex.
Do not switch Codex into Plan mode as a workaround. Plan mode injects Codex-native planning behavior and conflicts with this leader workflow.
Step 4: Preview & Create Task
Before creating, show the user the exact task that will be created using AskUserQuestion. Format the preview as:
📋 Task Preview
Title: <concise action phrase>
Board: <board-name>
Repo: <repo-name>
Agent: <agent-name>
Runtime: <agent-runtime>
Review owner: <active maintainer id or "leader">
Labels: <labels>
Depends on: <task-ids or "none">
## Goal
<one sentence>
## Files
- <file path> — <what changes>
## Spec
<concrete behavior: inputs, outputs, edge cases, error handling>
## Checks
- [ ] <verifiable condition — reviewer will check each one in Gate 2>
Examples by task type:
- API: "POST /api/items returns 201 with { id, name }"
- API: "empty name returns 400 with validation error"
- UI: "clicking Submit creates the item and navigates to detail page"
- UI: "empty form shows inline validation, submit button stays disabled"
- CLI: "ak get task --board xxx prints task table with status column"
---
Create this task? (y/n)
Everything from ## Goal through ## Checks is the exact text that will be passed to --description. The header fields above it (Title, Board, Agent, Runtime, etc.) are metadata for display only — do not include them in --description. The user must see the full description before it's sent to the agent.
Before running ak create task, verify:
- Selected agent is a worker.
- Selected agent has
status.schedulable: true.
- If the user specified runtime, selected agent runtime matches it.
- If the user specified runtime, that runtime is schedulable.
- If runtime was ambiguous, the user chose the runtime.
- Task Preview includes Runtime and Agent.
- Task Preview includes the resolved Review owner.
- Labels exist on the board, are stable taxonomy labels, and exclude one-off implementation details.
--assign-to uses the selected agent ID.
On confirmation, create the task:
ak create task \
--board <board-id> \
--repo <repo-id> \
--assign-to <agent-id> \
--title "<concise action phrase>" \
--description "<detailed spec>" \
--labels "<comma-separated>"
--assign-to is mandatory. Always include it on create. Only assign to an agent whose status.schedulable is true. If the right role only exists on an unschedulable runtime, create a new worker with the required capability profile on a schedulable runtime and assign to that worker. Use references/agent-creation.md; do not create workers from role/runtime alone.
Dependencies: If this task touches files that overlap with other in-flight tasks, add --depends-on <task-id>. Create all related tasks upfront with DAG dependencies — don't wait for one to finish before creating the next.
Task Creation Best Practices
- Create one task for one reviewable outcome.
- Split by feature/module boundary and context overlap, not by human job title.
- Keep highly overlapping work in one task, even if it touches frontend, backend, CLI, schema, and tests.
- Split only when work is independently understandable, independently reviewable, and has low file/data/API context overlap.
- Make the title an action phrase, not a vague topic.
- Put implementation constraints and acceptance checks in
--description; do not rely on chat context.
- Include concrete files, commands, endpoints, UI states, and error cases when known.
- Assign only to worker agents with
status.schedulable: true.
- Use
--depends-on for real blockers or overlapping context. Parallel tasks must not fight over the same files, data model, or API contract.
- Create missing reusable labels first with
ak create label --board <board-id> --name <name> --color <hex> --description "<desc>".
Report to user: task ID, title, assigned agent.
Phase 2: Monitor & Finish
Step 5: Monitor
Block on ak wait instead of writing polling loops. Exit codes: 0 condition
met, 2 task cancelled, 124 timeout.
In maintainer-review mode, wait for the terminal outcome:
ak wait task <task-id> --until done --timeout 1h
Do not stop at in_review to perform review work. On timeout, inspect task and
runtime state, then re-check review ownership with
ak get maintainer --board <board-id> -o json. If any maintainer is still
active, inspect that active maintainer's status and recent runs with
ak get maintainer <maintainer-id> --board <board-id> --runs; resolve runtime
or platform blockers and continue waiting without taking over review. If no
active maintainer remains, switch to leader-review mode.
In leader-review mode, wait for review:
ak wait task <task-id> --until in_review --timeout 1h
case $? in
0) ;;
2) echo "task cancelled — report unsuccessful terminal outcome" ; exit 1 ;;
124) echo "timed out — investigate" ;;
esac
Run ak wait task --help for the full flag list.
Before starting or recovering any wait, follow
references/wait-monitoring.md. The same wait policy applies to task waits and
board waits.
On timeout (124) or if you suspect the agent is stuck, investigate immediately — don't just re-wait:
- Check daemon logs:
ak logs --lines 20
- Check if agent process is alive:
ps aux | grep "claude.*session"
- Check agent session log for what it's doing or where it's stuck
- Check child processes: the agent may be stuck on a hook, install, or network call
Step 6: Review PR — leader-review mode only
Skip this step entirely in maintainer-review mode.
Pre-check: CI status. Before reviewing, verify CI has passed on the PR:
gh pr checks <pr-number> --repo <owner>/<repo>
If CI is pending or failed, reject immediately — worker must wait for CI to pass before submitting for review:
ak task reject <task-id> --reason "CI not green — wait for CI to pass before submitting for review"
Three gates — code review, functional acceptance, and agent notes review — must
pass before merging. Follow the shared verification policy in
references/leader-verification.md, including waiver evidence and verification
infrastructure learning.
Gate 1: Code Review
Read the full PR diff and review against the task spec:
gh pr view <pr-number> --repo <owner>/<repo> --json title,body,additions,deletions,changedFiles
gh pr diff <pr-number> --repo <owner>/<repo>
Check:
- Does the implementation match the task spec?
- Code quality — logic errors, bad abstractions, security issues
- Boundary awareness — CLI user-facing output vs internal logging, public API vs private
- Missing or broken test updates
- Dropped functionality (lost stack traces, removed useful info, etc.)
Fails → reject immediately, don't proceed to Gate 2.
Gate 2: Functional Acceptance
Apply references/leader-verification.md. Passing tests, CI, and code review
is not completion. Validate every task check from the product/user perspective.
If verification cannot be completed, follow the shared attempt budget, waiver,
and verification infrastructure learning rules.
Gate 3: Agent Notes Review
Read task notes before merging:
ak get note --task <task-id>
Check:
- The worker summarized what was done.
- Whether the worker proposed any durable process or principle change for its agent profile.
- Any proposal includes the reason, exact fields to change, and complete candidate
Agent YAML using the same metadata.name username as the current agent.
If the completion summary is missing or unclear, reject and ask the worker to add it.
If no proposal is present, continue. If a proposal is present, review it using references/runtime-delegation.md. Apply it only when the proposal is durable, role-appropriate, and not task-specific.
Step 7: Decide — act immediately, do not ask the user
Any gate fails or is blocked → Reject. List all issues in the reason.
ak task reject <task-id> --reason "<all issues, specific and actionable>"
After reject, go back to Step 5 and keep monitoring. If the failure reveals a durable worker behavior problem, apply references/runtime-delegation.md#leader-driven-profile-iteration: use reject to correct the current active session, or close/cancel the task if it is too far off-course; update the worker profile only after the current task is no longer being worked, and never change the agent runtime.
All gates pass, or Gate 2 is explicitly waived after the required attempt
budget → Post verification comment, then merge.
Post evidence on the PR before merging using the verification comment template in
references/leader-verification.md. Before running gh pr merge, re-read the
comment and confirm it satisfies the shared policy.
If the PR has merge conflicts, reject instead of merging — the worker agent will rebase, fix, and resubmit:
ak task reject <task-id> --reason "merge conflicts with main — rebase and resubmit"
Then merge:
gh pr merge <pr-number> --repo <owner>/<repo> --squash --delete-branch
The daemon's PR Monitor will mark the task done. Do not manually run
ak task complete unless the PR Monitor lag rule in
references/wait-monitoring.md applies.
Cleanup after merge
Remove local review artifacts from the repo root after verifying each path belongs to this workflow:
- temporary review worktrees under
/tmp/ak-review-*
playwright-report/test-results/
Phase 3: Exception Handling
In maintainer-review mode, use the following cancellation procedures only for
an explicit user cancellation or non-review operational teardown. Never close,
cancel, or recreate a task merely because maintainer review is slow, blocked,
or disagrees with the leader; investigate maintainer/runtime state instead.
Removing a task in todo
Tasks in todo status cannot be cancelled — delete them directly:
ak delete task <task-id>
Canceling an active task
For tasks in in_progress or in_review: always close the PR first, then cancel. Closing the PR without canceling is fine — PR Monitor will auto-cancel. But canceling without closing the PR leaves orphaned PRs.
gh pr close <pr-number> --repo <owner>/<repo> --delete-branch
ak task cancel <task-id>
Stuck rejected task
If a rejected task stays in_progress without being picked up:
- Check daemon logs — is it detecting the rejection?
- In leader-review mode, if the runtime is down or not tracking, close the PR, cancel, and recreate with the original spec, review feedback, and existing PR branch reference.
- In maintainer-review mode, resolve dispatch/runtime health without replacing the maintainer's rejection or recreating the task on the leader's authority.
- Always use
--assign-to on recreate.
CI failure
In leader-review mode, investigate the failure. If it is a source bug, reject
with details. If it is flaky CI, re-trigger. In maintainer-review mode, do not
make the review decision or reject the task; let the active maintainer handle
CI evidence while the leader continues operational monitoring.
AK command, product, or skill issue
If the blocker appears to be an ak bug, missing capability, confusing UX, documentation gap, or skill workflow problem, file an issue in the official repo after collecting a minimal reproduction.
If the leader agent makes a process error, violates this skill, merges/rejects incorrectly, skips a required gate, misinterprets conflicting skill instructions, or has to be corrected by the user about expected skill behavior, do not stop at a chat apology or "next time" promise. Summarize the failure as a durable skill-improvement issue so future agents and external projects can benefit from the lesson. Include:
- What the agent did wrong.
- Which skill text was unclear, incomplete, contradictory, or too weak to prevent the error.
- The exact rule or wording that should be added or changed.
- Any local skill edits already made during the incident.

Rules
- Workflow completion is mandatory — once this skill is invoked, the full lifecycle (create → assign → monitor → terminal outcome) MUST run to completion. Success requires
done; cancelled is an unsuccessful terminal outcome that must be reported, not left pending or described as completion.
- Before task creation: human-in-the-loop. Discuss scope, resolve ambiguity, preview the exact task, and get explicit user confirmation before creating it.
- After task creation: human-not-in-the-loop. The user is no longer part of execution control unless they explicitly interrupt with a new instruction. The leader must continue until the work cycle completes. The active board maintainer owns review when present; otherwise the leader owns review.
- After
ak create task, continue immediately into monitoring (ak wait task ...) in the same turn whenever possible. Do not send a final answer merely reporting that the task was created unless the user explicitly says to stop, cancel, abort, or only create the task.
- If execution hits a blocker after task creation, solve it autonomously: inspect state, fix environment issues, reject blocked PRs with actionable reasons in leader-review mode, create follow-up issues when the platform/skill is at fault, or wait for the task/PR. Do not stop and hand the blocker back to the user unless the user is the only possible source of required information or explicitly pauses the workflow.
- If you are interrupted mid-workflow (user asks a side question, chat drifts to another topic, tool fails, etc.), handle the interruption and then immediately resume the workflow from where you left off. Never ask "should I continue monitoring?" or "do you want me to keep going?" — the answer is always yes. The only way to exit the workflow early is if the user explicitly says to stop, cancel, or abort.
- Follow CONTRIBUTING.md — read the target repo's CONTRIBUTING.md before creating tasks; check PR compliance during review
- Investigate before creating — read the code first, don't create vague tasks
- One coherent outcome per invocation — if the user describes multiple unrelated or low-overlap outcomes, create one and suggest splitting the rest
- Detailed descriptions — agents are autonomous, the description is their only input
- Check for duplicates — look at existing tasks before creating
- Resolve review ownership first — use
ak get maintainer --board <board-id> -o json; only status: active delegates review, and does not affect ownership
