pm-tasks

name: pm-tasks description: > Work off tasks from an external project management tool (Asana, Linear, Jira, etc.). Use when the user says "pick a task", "next task", "what should I work on", "update task", "create task", "mark done", "task status", or similar PM workflow requests. Also activates when starting a new work session and needing to select work. ONLY load this skill when CLAUDE.md configures an external PMT with a tool value other than "none". Do NOT load this skill if the project uses markdown or txt files for task tracking (use the working-off-of-todo-files skill instead).

Work off tasks from an external project management board. This skill handles the full lifecycle: picking tasks, tracking status, creating new tasks, and marking work complete.

Configuration

On activation, read the project's CLAUDE.md (or CLAUDE.local.md) for a ### Project Management section. It contains:

PM tool or equivalent: which MCP integration to use (e.g., Asana MCP, Linear MCP)
Shared project: the team's board (URL/GID and section names)
Agent project: the agent's private scratchpad board (optional)
Content format: html (Asana) or markdown (Linear, Jira)

If this section is missing or says tool: none, fall back to the working-off-of-todo-files skill and work from ai-notes/**/todo.md.

Workflow

1. Resume Session (ALWAYS do this first)

On activation, before picking new tasks, read both PID files: tmp/current-task.pid and tmp/current-parent-task.pid.

If tmp/current-task.pid exists and tmp/current-parent-task.pid does not, fetch the current task from the PM tool and resume it. This is the normal top-level task flow.
- If the fetched task is already completed, verify completion in the PM tool, clear tmp/current-task.pid, and proceed to "Pick Next Task".
- If the current task is in this agent's "blocked/needs input" section on the agent board, announce the blocked state and stop for user input.
- Before doing parent-level implementation work, fetch the task's direct subtasks when the PM tool supports them. If incomplete direct subtasks exist, this is a parent container that was interrupted before Subtask Selection. Confirm it is still this agent's claimed container when an agent board is configured, then run "Subtask Selection" instead of implementing the parent body. If it is not claimed by this agent, clear both PID files and proceed to "Pick Next Task".
If both PID files exist, the current task is a subtask and the parent task is the claimed container. Fetch both records before doing anything else.
- If the parent task is already completed, stop and ask the user for confirmation before continuing. Do not silently work under a completed parent. The user can choose whether to release the local claim and clear both PID files, reopen/continue the parent, or inspect the task history first.
- If the parent container is in this agent's "blocked/needs input" section on the agent board, announce the blocked state and stop for user input.
- If the active subtask is incomplete, still belongs to the parent, and is still assigned to the current user/agent or unassigned, announce the parent and active subtask, then continue work on the subtask.
- If the active subtask is already completed, run "Subtask Transition" to select the next eligible direct subtask or prepare the parent for explicit completion. Do not mark the already-completed subtask complete again.
- If the active subtask no longer belongs to the parent, or was reassigned to someone else while this agent was offline, fetch the parent's remaining direct subtasks and run "Subtask Selection" again. Do not mark the parent complete during this recovery.
If tmp/current-parent-task.pid exists but tmp/current-task.pid does not, treat this as stale local state from an interrupted subtask transition. Fetch the parent task, confirm it is still this agent's claimed container when an agent board is configured, then run "Subtask Selection" again. If the parent is not claimed by this agent, clear both PID files and proceed to "Pick Next Task".
If neither PID file exists, this agent has NO in-progress work. Do NOT fetch the agent board's "current work" section to find tasks; those tasks belong to OTHER agents running in other worktrees. Proceed directly to "Pick Next Task".
Exception - dirty git status: If no PID file exists but git status shows uncommitted changes, inspect them to infer what was being worked on. If you can match changes to a task on the shared board's "in progress" section, ask the user whether to resume it. If you're confused, ask the user what to do.

Why the PID files are authoritative: In a multi-worktree setup, multiple agents share the same agent board. The PID files live inside tmp/, which is per-worktree, making them the only reliable indicator of what THIS specific agent is working on.

2. Pick Next Task

When the user says "pick a task", "next task", "what should I work on" (and no in-progress work exists from step 1):

Fetch incomplete tasks from the shared board's priority section (the section designated for "ready to start" work, e.g., "Up next", "Todo", "Ready"). Use the PM tool's completion filter (e.g., Asana's opt_fields=completed and filter client-side) to exclude tasks already marked as done. Sort by priority. If tasks have a Priority field (custom field, label, or tag), always fetch it in the same request and sort results High > Medium > Low > unset before presenting candidates. Never present tasks in arbitrary section order when priority data is available. Skip tasks assigned to someone else. If a task has an assignee and that assignee is not the current user (or the agent), do not include it in the candidate list — someone else is responsible for it. Unassigned tasks are fair game.
If a private agent board is configured, also fetch its "current work" section to see which tasks other agents are already working on. Exclude those from the candidates presented to the user. The agent board fetch is mandatory, not best-effort. If the fetch fails (network error, timeout, MCP error), retry up to 2 times. If still failing, STOP and tell the user: "I can't fetch the agent board to check what other agents are working on. Proceeding without this check risks picking a task that's already claimed." Do NOT proceed without the exclusion list.
If a private agent board is configured, list tasks that are marked as Blocked or Needs Input so the user can act on them.
Present the top 3-5 tasks with titles and short summaries.
Let the user choose, or pick the first one if they say "just pick one".
If the user rejects a pick (e.g., "that one is taken", "pick another"), re-fetch the agent board's "current work" section before picking again. The exclusion list may have changed since the original fetch.
Do not write PID files during picking. The selected task is not this agent's durable work until "Start Working on a Task" claims it on the shared board and agent board. Subtask selection also does not happen in this phase; it happens only after the selected parent task is claimed.

2a. Subtask Selection

Run Subtask Selection only after the selected top-level parent task has been claimed on the shared board and, when configured, on the private agent board. The board claim belongs to the parent container; the active subtask is tracked only in local PID state unless the PM tool has an explicit subtask workflow.

Fetch the selected parent task's direct subtasks before doing any work on the parent. Include completion status, assignee, priority if available, and parent relationship in the response.
- Do not recurse into nested subtasks. Grandchildren belong to the selected subtask's own scope and are not auto-claimed by this workflow.
Partition direct subtasks into:
- completed subtasks, which are ignored;
- eligible incomplete subtasks, which are unassigned or assigned to the current user/agent;
- ineligible incomplete subtasks, which are assigned to someone else.
If there are eligible incomplete subtasks:
- Auto-pick one subtask because the user already selected or approved the parent container. Prefer priority order if priority data is available; otherwise use the PM tool's direct subtask order.
- Keep the parent task incomplete and in progress. Do NOT mark the parent complete.
- Keep the parent task on the agent board's "current work" section to reserve the container. Do not duplicate the parent task.
- Write the parent task id to tmp/current-parent-task.pid first, then write the active subtask id to tmp/current-task.pid. Parent-first ordering makes crash recovery land in the stale-parent recovery path instead of treating a subtask as a top-level task.
- Announce both names: "Working on subtask X under parent task Y."
If the parent has incomplete direct subtasks but none are eligible, release this agent's claim and return to "Pick Next Task":
- add a parent-task comment explaining that this agent is releasing the container because all remaining incomplete direct subtasks are assigned to other people;
- remove only this agent's parent container from the agent board's "current work" section when an agent board is configured;
- clear both PID files;
- leave the parent task incomplete and do not mark it done;
- leave the parent in the shared board's "in progress" section because the remaining direct subtasks have explicit non-agent owners.
If the parent has no direct subtasks at all, remove any stale tmp/current-parent-task.pid, keep the parent id in tmp/current-task.pid, and continue with the parent as the active top-level work item.
If the parent has direct subtasks and zero incomplete direct subtasks, remove any stale tmp/current-parent-task.pid and keep the parent id in tmp/current-task.pid. The parent is now the completion target, not an implementation task. Ask the user whether to mark it complete; do not invent extra parent-body work unless the user says the parent has remaining work.
While a parent is claimed, "next task" means the next eligible direct subtask under that parent. "Switch tasks", "different task", or an equivalent explicit redirect means release this agent's parent claim, clear both PID files, and return to the top-level task queue.

2b. Subtask Transition

Use this after an active subtask is completed, or when resume discovers the active subtask was already completed elsewhere. This section does not mark any task complete; it only chooses the next local state after completion is already true in the PM tool.

Fetch the parent task's remaining incomplete direct subtasks.
If another eligible incomplete subtask exists, pick it next, write its id to tmp/current-task.pid, keep tmp/current-parent-task.pid, and announce the transition. Continue with that subtask rather than picking a new top-level task.
If incomplete direct subtasks remain but none are eligible, add a parent-task comment explaining that this agent is releasing the container because all remaining incomplete direct subtasks are assigned to other people. Remove only this agent's parent container from the agent board's "current work" section when configured, clear both PID files, leave the parent incomplete, and return to "Pick Next Task". Leave the parent in the shared board's "in progress" section because the remaining direct subtasks have explicit non-agent owners.
If no incomplete direct subtasks remain, write the parent task id back to tmp/current-task.pid, delete tmp/current-parent-task.pid, and tell the user the subtask queue is finished. The parent is now only a completion target. Wait for explicit confirmation before marking the parent task complete; do not implement extra parent-body work unless the user says there is remaining parent-level work.

3. Start Working on a Task

When a task is selected, claim it on the board IMMEDIATELY — before reading details, comments, or doing any other work. This is a recurring failure mode: the agent reads task details, launches a spec or plan, and never moves the task on the board. Claim first, explore second.

Do ALL of these steps in order:

PHASE 1: CLAIM THE TASK (do this BEFORE anything else)

Verify not already claimed. The task being claimed here is the selected top-level task or parent container. Check that it is not already on the agent board's "current work" section. Also treat the parent as claimed if any current agent-board item is a subtask under that parent. If another agent already claimed it, do NOT proceed. Clear both PID files and return to "Pick Next Task".
Move the parent task to the "in progress" section on the shared board. This is the FIRST visible action. Do it NOW. Do not try to move subtasks through top-level board sections; in tools like Asana, subtasks often do not belong to those sections.
Add the parent task to the agent board (REQUIRED if configured). Multi-home the parent task to the agent board's "current work" section. Use multi-homing (Asana addProject API) or cross-project references (Linear) - never duplicate the task. Do not skip this step.
Write tmp/current-task.pid with the parent task id and delete any stale tmp/current-parent-task.pid. At this point the parent is visibly claimed on the board, so later subtask PID changes cannot create an invisible race.

PHASE 2: UNDERSTAND THE TASK (only after Phase 1 is complete)

Read the parent task's full description from the PM tool.
Read the parent task's comment history (e.g., Asana stories). Comments often contain scoping decisions, open questions, or prior agent triage notes. If the comments indicate that the task still needs scoping or shaping (e.g., open questions, "triage needed", multiple competing approaches, unclear requirements), do NOT jump into implementation. Instead:
- Summarize the current state of the discussion.
- Propose a plan or recommendation addressing the open questions.
- Wait for the user's approval before writing any code.
Run Subtask Selection exactly once for the claimed parent. If it selects an active subtask, read that subtask's full description and comments before coding.
Announce the active work item title, parent title when present, description summary, and key requirements to establish context for the session.

4. Update Task Status

When the user says "update task", "add note", "blocked":

Add context: post a comment or note on the active task in the PM tool. If the active task is a subtask, mention the parent task in the note so the thread is understandable later.
Blocked top-level task: if no parent PID exists and a private agent board is configured, move the active task to the "blocked/needs input" section there. Leave position on the shared board unchanged.
Blocked subtask: if tmp/current-parent-task.pid exists, the active task is a subtask.
- Post the blocking context on the subtask and parent task.
- Move the parent container to the agent board's "blocked/needs input" section when configured, keep both PID files, and stop for user input.
- If no agent board is configured, there is no durable machine-readable blocked state for future sessions. Say that explicitly, keep both PID files, and stop for user input. Do not pretend the block can be safely remembered across restarts.
- Do not pick another direct subtask while the active subtask is blocked. Otherwise the blocked subtask still matches the normal eligibility filter and can be re-selected later.
- Do not pick an unrelated top-level task unless the user explicitly redirects the session.
Progress note: add a comment summarizing what was done so far.

5. Create a New Task

When the user says "create task", "new task", "write task":

Delegate to the write-task skill for content formatting. The write-task skill handles template selection (short vs full), content structure, and output format (HTML or markdown based on CLAUDE.md).
Use the PM tool's MCP to create the task in the shared project only.
Place in the section the user specifies, defaulting to the "inbox" or "triage" section.
Do NOT add the task to the agent board. Creating a task is not the same as working on it. The agent board's "current work" section is exclusively for tasks THIS agent is actively implementing. A newly created task should be visible on the shared board so the user (or a future agent session) can prioritize and pick it up through the normal "Pick Next Task" flow. Adding it to the agent board makes it invisible to other agents and implies someone is working on it when no one is.

6. Mark Task Complete

When the user confirms a task is done (or an automated completion criterion defined by the user is met):

Check whether tmp/current-parent-task.pid exists. If it does, the active task is a subtask and the parent task must stay incomplete.
If completing a top-level task with no active parent:
- First fetch direct subtasks when the PM tool supports them. If incomplete direct subtasks exist, do not mark the parent complete or silently re-enter Subtask Selection. Stop and ask the user to confirm whether to continue through the remaining subtasks or mark the parent complete despite incomplete direct subtasks. If the user chooses to continue through subtasks, run "Subtask Selection" and stop this completion flow. Continue to the next bullet only if the user explicitly confirms parent completion.
- Set the active task's completion status in the PM tool. This is NOT the same as moving it to a section; it means marking the task itself as done (e.g., Asana: asana_update_task with completed: true; Linear: update state to "Done"). Verify the API response confirms the task is now marked complete before proceeding.
- If a private agent board is configured, move the task to the "done" section there as well.
- CRITICAL: Delete tmp/current-task.pid and tmp/current-parent-task.pid. Only do so when the task was QA'd and successfully marked complete in the PM tool.
- Announce completion and ask if the user wants to pick the next task.
If completing a subtask:
- Set the active subtask's completion status in the PM tool and verify the API response confirms the subtask is now marked complete before proceeding. Note (Asana): Completed tasks automatically disappear from board views, so no section move is needed on the shared board.
- Leave the parent task incomplete and in progress.
- Do not remove the parent task from the agent board's "current work" section.
- Run "Subtask Transition" to select the next eligible direct subtask, release the parent if remaining direct subtasks belong to other people, or prepare the parent for explicit completion.

7. Read Task Details

When the user says "show task", "task details", "what's this task about":

Fetch the task from the PM tool.
Fetch subtasks when the PM tool supports them.
Display: title, description, assignee, current section, subtask completion summary, and recent comments or activity.

8. Session Status

When the user says "task status", "what am I working on":

Read both PID files. If tmp/current-task.pid is set, fetch that task from the PM tool. This is YOUR current task.
If tmp/current-parent-task.pid exists, also fetch the parent task and report that the current task is a subtask under that parent. Include the remaining incomplete direct subtask count when available.
If only tmp/current-parent-task.pid exists, report stale local state and follow Resume Session recovery before presenting status.
If no PID file exists, report that this agent has no task in progress.
If a private agent board is configured, list tasks in the "current work" section as other agents' work (for visibility, not for claiming).
If a private agent board is configured, list tasks that are marked as Blocked or Needs Input so the user can act on them.
Show title and brief status for each.

PM Tool Examples

This skill itself never contains tool-specific API calls. The CLAUDE.md configuration tells the agent which MCP tools to use and what section names map to each workflow state.

Asana Configuration Example

### Project Management

- **PM tool**: Asana MCP
- **Shared project**: My Project (GID: 1234567890)
  - Sections: Inbox, Up next, In progress, Backlog
  - "Ready" section: Up next
  - "In progress" section: In progress
- **Agent project**: AI Agent (GID: 0987654321)
  - Sections: Current session, Blocked/Needs input, Done
- **Content format**: html

Asana: fetching priority. To get priority data, include custom_fields,custom_fields.name,custom_fields.enum_value,custom_fields.enum_value.name in the opt_fields parameter when calling asana_get_tasks. The Priority custom field's enum_value.name will be "High", "Medium", or "Low". Tasks without a priority value will have enum_value: null.

Linear Configuration Example

### Project Management

- **PM tool**: Linear MCP
- **Shared project**: My Team (ID: TEAM-123)
  - States: Triage, Todo, In Progress, Done, Cancelled
  - "Ready" state: Todo
  - "In progress" state: In Progress
- **Agent project**: none
- **Content format**: markdown

No PM Tool (Fallback)

### Project Management

- **PM tool**: none
- **Fallback**: ai-notes/todo.md

When tool: none, activate the working-off-of-todo-files skill instead.

Principles

Single active work item: work on ONE task or subtask at a time until complete or blocked. A parent task can remain claimed as the container while the active work item is one of its subtasks.
User controls top-level pacing: never advance to an unrelated top-level task without the user's go-ahead. Within a claimed parent task, continue to the next eligible incomplete subtask after the current subtask is complete. "Next task" means the next subtask in the current parent; "switch tasks" or "different task" means release the parent and return to the top-level queue.
Direct subtasks only: this skill auto-selects only direct subtasks of the claimed parent. Nested subtasks are part of the selected subtask's scope and are not separate parent containers unless the user explicitly selects them.
Shared board is source of truth: the private agent board is a scratchpad. Status on the shared board is what teammates see.
Don't duplicate tasks: use multi-homing or cross-references, never copy tasks between boards.
Announce transitions: always tell the user when you move a task between sections or mark it complete.
Never modify other agents' state. Only add or remove YOUR active task (tmp/current-task.pid) or parent container (tmp/current-parent-task.pid) on the agent board. Never remove, move, or update tasks that belong to other agents. If you accidentally claimed a task that another agent owns, simply clear both PID files and pick a different task; do not touch the other agent's board entry.
