Aitask Pickrem

Overview

This skill is a fully autonomous version of aitask-pick + task-workflow designed for environments where AskUserQuestion does not work (e.g., Claude Code Web). It combines task selection and implementation into a single self-contained workflow with zero interactive prompts. All decisions are driven by an execution profile.

Key differences from aitask-pick:

• Task ID is a required argument (no interactive browsing/selection)
• No AskUserQuestion calls anywhere in the workflow
• No worktree/branch management (always works on current branch)
• Auto-commits after implementation (no user review loop)
• Profile is required and auto-selected (not prompted)

Arguments

Required: Task ID (first positional argument)

• Format 1: Parent task number (e.g., 42)
• Format 2: Child task ID (e.g., 42_2)

IMPORTANT: This skill will NOT work without a task ID argument. If invoked without one, display an error and abort.

Workflow

Step 0: Initialize Data Branch (if needed)

Ensure the aitask-data worktree and symlinks are set up:

./.aitask-scripts/aitask_init_data.sh

This is a no-op for legacy repos and already-initialized repos. Required for Claude Code Web where ait setup has not been run.

Parse stdout:

• INITIALIZED — Display: "Data branch initialized." Proceed.
• ALREADY_INIT / LEGACY_MODE / NO_DATA_BRANCH — Proceed silently.

If the command fails (non-zero exit), display the error and abort.

Step 1: Load Execution Profile

Execute the Execution Profile Selection Procedure — Auto-Select (see .claude/skills/task-workflow/execution-profile-selection-auto.md) with mode_label = "Remote".

Step 2: Resolve Task File

Parse the task ID argument:

Format 1: Parent task (e.g., 42):

• Find the matching task file and check for children in a single call:

  ./.aitask-scripts/aitask_query_files.sh resolve <number>
  

  Parse the output: if first line is NOT_FOUND, display error "Task t<N> not found" and abort. If first line is TASK_FILE:<path>, use that path. If second line is HAS_CHILDREN:<count>, display error "Task t<N> has child subtasks. Specify a child task ID (e.g., \<N\>_1) instead." Abort. If NO_CHILDREN, proceed with this task.

Format 2: Child task (e.g., 42_2):

• Parse as child task ID (parent=42, child=2)
• Find the matching child task file:

  ./.aitask-scripts/aitask_query_files.sh child-file <parent> <child>
  

  Parse the output: CHILD_FILE:<path> means found (use that path), NOT_FOUND means not found.
• If not found: display error "Child task t<parent>_<child> not found" and abort.
• Set this as the selected task
• Read the task file and parent task file for context
• Gather sibling context in a single call:

  ./.aitask-scripts/aitask_query_files.sh sibling-context <parent>
  

  Parse the output: lines prefixed ARCHIVED_PLAN: are archived sibling plan files (primary context source for completed siblings). Lines prefixed ARCHIVED_TASK: are fallback for siblings without archived plans. Lines prefixed PENDING_SIBLING: are pending sibling task files. Lines prefixed PENDING_PLAN: are pending sibling plans. If output is NO_CONTEXT, there are no sibling context files. Read the files listed in the output.

Display: "Selected task: <task_filename>" with a brief 1-2 sentence summary.

Set context variables:

• task_file: Path to the selected task file
• task_id: Task identifier (e.g., 42 or 42_2)
• task_name: Filename stem (e.g., t42_implement_auth or t42_2_add_login)
• is_child: true if child task, false otherwise
• parent_id: Parent task number if child, null otherwise
• parent_task_file: Path to parent task file if child, null otherwise
• previous_status: The task's current status (before modification)

Step 3: Sync with Remote (Best-effort)

./.aitask-scripts/aitask_pick_own.sh --sync

Non-blocking — if it fails (e.g., no network, merge conflicts), continue silently.

Step 4: Task Status Checks

Check 1 — Done but unarchived task:

• Read the task file's frontmatter status field
• If status is Done:
  • Read done_task_action from profile (default: archive)
  • If archive: display "Profile: auto-archiving Done task t<N>". Skip to Step 10 (Archive).
  • If skip: display "Task t<N> has status Done, skipping per profile." End workflow.

Check 2 — Orphaned parent task:

• Check if the task file's frontmatter contains children_to_implement: [] (empty list)
• If empty, check for archived children:

  ./.aitask-scripts/aitask_query_files.sh archived-children <number>
  

  Parse the output: ARCHIVED_CHILD:<path> lines mean archived children exist, NO_ARCHIVED_CHILDREN means none.
• If archived children exist:
  • Read orphan_parent_action from profile (default: archive)
  • If archive: display "Profile: auto-archiving orphaned parent t<N>". Skip to Step 10 (Archive).
  • If skip: display "Orphaned parent t<N>, skipping per profile." End workflow.

If neither check triggers, proceed to Step 5.

Step 5: Assign Task

• Email resolution (priority order, non-interactive):

  1. Check task metadata: Read the assigned_to field from the task file's frontmatter.
  2. Check userconfig: Read aitasks/metadata/userconfig.yaml and extract the email: field (if file exists).
  3. Mismatch check (non-interactive): If both assigned_to and userconfig email are non-empty and DIFFERENT: prefer assigned_to. Display warning: "Warning: assigned_to (<email1>) differs from userconfig (<email2>). Using assigned_to."
  4. If assigned_to is non-empty (and matches userconfig, or userconfig is empty): use assigned_to. Display: "Using email from task metadata: <email>"
  5. Profile check: Read default_email from profile:
     • If "userconfig": Use the userconfig email (from step 2). If empty/missing, fall back to first email from aitasks/metadata/emails.txt. If both empty, proceed without email.
     • If "first": read aitasks/metadata/emails.txt and use the first email address. If file is empty or missing, proceed without email.
     • If a literal email address: use that directly.
     • If not set in profile: proceed without email.

• Claim task ownership:

  If email was resolved:

  ./.aitask-scripts/aitask_pick_own.sh <task_num> --email "<email>"
  

  If no email:

  ./.aitask-scripts/aitask_pick_own.sh <task_num>
  

• Parse the script output:

  • OWNED:<task_id> — Success. Display: "Task t<N> claimed (email: <email>)". Proceed to Step 6.
  • FORCE_UNLOCKED:<previous_owner> + OWNED:<task_id> — Force-unlock succeeded. Display: "Force-unlocked stale lock held by <previous_owner>. Task t<N> claimed." Proceed to Step 6.
  • LOCK_FAILED:<owner>|<locked_at>|<hostname> — Parse the owner from the first |-separated field. Read force_unlock_stale from profile (default: false):
    • If true: Display "Profile: force-unlocking stale lock held by <owner>". Re-run with --force:

      ./.aitask-scripts/aitask_pick_own.sh <task_num> --force --email "<email>"
      

      Parse output again. If FORCE_UNLOCKED + OWNED: proceed. Otherwise: abort.
    • If false: Display error: "Task t<N> is locked by <owner>. Pick a different task." Abort.
  • LOCK_ERROR:<message> — Display error: "Lock system error: <message>. Run ./.aitask-scripts/aitask_lock_diag.sh for troubleshooting." Abort.
  • LOCK_INFRA_MISSING — Display error: "Lock infrastructure not initialized. Run ait setup." Abort.

  If the script fails entirely (non-zero exit without structured output), display the error and abort.

Step 6: Environment Setup

Remote mode always works on the current branch. No worktree or branch management.

Display: "Working on current branch (remote mode)"

Step 7: Create Implementation Plan

7.0: Check for Existing Plan

Check if a plan file already exists:

• For parent tasks: aiplans/p<taskid>_*.md
• For child tasks: aiplans/p<parent>/p<parent>_<child>_*.md

./.aitask-scripts/aitask_query_files.sh plan-file <taskid>

Parse the output: PLAN_FILE:<path> means found, NOT_FOUND means not found.

If a plan file exists, read it.

• Read plan_preference from profile (default: use_current):
  • use_current: Display "Profile: using existing plan". Skip to Step 7 Checkpoint.
  • verify: Display "Profile: verifying existing plan". Enter plan mode (Step 7.1), starting by reading and verifying the existing plan.
  • create_new: Display "Profile: creating plan from scratch". Enter plan mode (Step 7.1).

If no plan file exists, proceed to Step 7.1.

7.1: Planning

Use the EnterPlanMode tool to enter Claude Code's plan mode.

If entering from the "verify" path: Start by reading the existing plan file. Explore the current codebase to check if the plan's assumptions, file paths, and approach are still valid. Update the plan if needed.

For child tasks: Include context links (in priority order):

• Parent task file: aitasks/t<parent>_<name>.md
• Archived sibling plan files: aiplans/archived/p<parent>/p<parent>_*_*.md
• Archived sibling task files (fallback): aitasks/archived/t<parent>/t<parent>_*_*.md
• Pending sibling task files: aitasks/t<parent>/t<parent>_*_*.md
• Pending sibling plan files: aiplans/p<parent>/p<parent>_*_*.md

While in plan mode:

• Explore the codebase to understand the relevant architecture
• Folded Tasks Note: If the task has a folded_tasks frontmatter field, the task description already contains all relevant content from the folded tasks. No need to read the original folded task files.
• Complexity: Always implement as a single task (do NOT break into child subtasks — child creation requires interactive prompts not available in remote mode)
• Testing requirement: When the task involves code changes (not documentation/config-only tasks), the implementation plan MUST include a "Verification" section specifying:
  • What automated tests to write or update
  • What existing tests to run
  • Expected outcomes
  • For non-code tasks (documentation, config, skill files), a simple verification step (e.g., lint check, visual review of output) is sufficient
• Create a detailed implementation plan
• Include a reference to Step 10 (Archive) for post-implementation cleanup
• Use ExitPlanMode when ready for user approval

Save Plan to External File

After the user approves the plan via ExitPlanMode, save it.

File naming convention:

For parent tasks:

• Location: aiplans/
• Filename: Replace t prefix with p
• Example: t16_implement_auth.md → aiplans/p16_implement_auth.md

For child tasks:

• Location: aiplans/p<parent>/
• Filename: Replace t prefix with p
• Example: t16_2_add_login.md → aiplans/p16/p16_2_add_login.md

Required metadata header for parent tasks:

---
Task: t16_implement_auth.md
Branch: (current branch, remote mode)
---

Required metadata header for child tasks:

---
Task: t16_2_add_login.md
Parent Task: aitasks/t16_implement_auth.md
Sibling Tasks: aitasks/t16/t16_1_*.md, aitasks/t16/t16_3_*.md
Archived Sibling Plans: aiplans/archived/p16/p16_*_*.md
Branch: (current branch, remote mode)
---

Step 7 Checkpoint

Read post_plan_action from profile (default: start_implementation).

• start_implementation: Display "Profile: proceeding to implementation". Proceed to Step 8.
• If not set: proceed to Step 8 (default behavior for remote is always to continue).

Step 8: Implement

Pre-implementation ownership guard:

Before starting implementation, verify that ownership/lock was acquired (Step 5 should have done this, but this guard catches edge cases like plan mode deferral):

• Read the task file's frontmatter status and assigned_to fields
• Resolve the current user's email: use the email from Step 5 if available, otherwise from aitasks/metadata/userconfig.yaml or profile default_email
• If status is Implementing AND assigned_to matches the current user's email: Ownership was already acquired in Step 5. Proceed normally.
• Otherwise (status is not Implementing, or assigned_to is empty/missing, or assigned_to does not match the current user's email): Ownership was not properly acquired. Display: "Guard: task ownership not confirmed — acquiring ownership now."
  • Run the ownership claim:

    ./.aitask-scripts/aitask_pick_own.sh <task_num> --email "<email>"
    

  • Parse output: OWNED → proceed. Any failure (LOCK_FAILED, LOCK_ERROR, LOCK_INFRA_MISSING, or script error) → trigger the Abort Procedure.
  • No AskUserQuestion calls (remote mode constraint).

Record implementing agent: Execute the Agent Attribution Procedure (see ../task-workflow/agent-attribution.md) to record which code agent and model is implementing this task.

Follow the approved plan, working in the current directory.

Update the external plan file as you progress:

• Mark steps as completed
• Note any deviations or changes from the original plan
• Record issues encountered during implementation

Testing (when applicable):

• After implementation is complete, run all relevant automated tests if the task involves code changes
• If tests fail, attempt to fix the issues before proceeding to Step 9
• If tests cannot be fixed after reasonable attempts, trigger the Abort Procedure instead of committing broken code
• If no tests are applicable (documentation, config, skill file tasks), proceed directly to build verification

Build verification (if configured):

• Read aitasks/metadata/project_config.yaml and check the verify_build field
• If verify_build is absent, null, or empty (or file doesn't exist): Display "No verify_build configured — skipping build verification." and skip.
• If configured: Run the command(s). If a single string, run it. If a list, run sequentially (stop on first failure).
• If the build fails:
  1. Analyze the error output and compare against the changes introduced by this task
  2. If caused by this task's changes: Go back to fix the build errors. After fixing, re-run. Repeat until the build passes.
  3. If NOT related to this task's changes (pre-existing issue): Log the build failure in the plan file's "Final Implementation Notes" and proceed. Do not attempt to fix pre-existing issues.

Step 9: Auto-Commit

Read review_action from profile (default: commit).

1. Show change summary:

   git status
   git diff --stat
   

2. Check for changes:

   git status --porcelain
   

   If no changes detected, display warning "No changes detected after implementation" and skip to Step 10.

3. Consolidate the plan file:

   • Read the current plan file from aiplans/
   • Review git diff --stat against the plan
   • Add or update a "Final Implementation Notes" section:

     ## Final Implementation Notes
     - **Actual work done:** <summary of what was actually implemented vs planned>
     - **Deviations from plan:** <any changes from the original approach and why>
     - **Issues encountered:** <problems found and how they were resolved>
     - **Key decisions:** <technical decisions made during implementation>
     - **Test results:** <summary of automated tests run and their outcomes>
     - **Notes for sibling tasks:** <patterns, gotchas, shared code> (include if child task)
     

   • IMPORTANT for child tasks: The plan file will be archived and serve as the primary reference for subsequent sibling tasks. Ensure the Final Implementation Notes are comprehensive.

4. Commit code changes and plan file separately:

   • Code commit:

     git add <changed_code_files>
     # First execute the Contributor Attribution Procedure and the
     # Code-Agent Commit Attribution Procedure from ../task-workflow/code-agent-commit-attribution.md,
     # then compose one final commit message.
     git commit -m "$(cat <<'EOF'
     <issue_type>: <description> (t<task_id>)
     
     <optional Based on PR block and contributor trailer>
     <optional code-agent trailer>
     EOF
     )"
     

     Only include implementation files — never aitasks/ or aiplans/ paths. Skip if no code changes. The <issue_type> comes from the task's frontmatter. Examples: feature: Add channel settings (t16), bug: Fix login validation (t16_2). If code-agent attribution fails, continue with the contributor-only or plain commit message.
   • Plan file commit:

     ./ait git add aiplans/<plan_file>
     ./ait git commit -m "ait: Update plan for t<task_id>"
     

     Skip if plan file was not modified.
   • Never mix code files and aitasks//aiplans/ files in the same git add or commit.
   • Display: "Changes committed: <commit_hash>"

5. Proceed to Step 10.

Step 10: Archive and Push

For child tasks — verify plan completeness:

• Read the plan file
• Verify it contains a "Final Implementation Notes" section with comprehensive details
• If missing or incomplete, add/update it now

Run the archive script:

For parent tasks:

./.aitask-scripts/aitask_archive.sh <task_num>

For child tasks:

./.aitask-scripts/aitask_archive.sh <parent>_<child>

Parse structured output and handle without prompts:

Read issue_action from profile (default: close_with_notes).

• ISSUE:<task_num>:<issue_url> — Handle based on issue_action:

  • close_with_notes:

    ./.aitask-scripts/aitask_issue_update.sh --close <task_num>
    

  • comment_only:

    ./.aitask-scripts/aitask_issue_update.sh <task_num>
    

  • close_silent:

    ./.aitask-scripts/aitask_issue_update.sh --close --no-comment <task_num>
    

  • skip: do nothing

• PARENT_ISSUE:<task_num>:<url> — Same handling as ISSUE using issue_action

• FOLDED_ISSUE:<folded_task_num>:<issue_url> — Same handling, but use the primary task_id for the script call:

  • close_with_notes:

    ./.aitask-scripts/aitask_issue_update.sh --issue-url "<issue_url>" --close <task_id>
    

  • comment_only:

    ./.aitask-scripts/aitask_issue_update.sh --issue-url "<issue_url>" <task_id>
    

  • close_silent:

    ./.aitask-scripts/aitask_issue_update.sh --issue-url "<issue_url>" --close --no-comment <task_id>
    

  • skip: do nothing

• FOLDED_WARNING:<task_num>:<status> — Display warning: "Folded task t<N> has status '<status>' — skipping deletion."

• PARENT_ARCHIVED:<path> — Display: "All child tasks complete! Parent task also archived."

• COMMITTED:<hash> — Display: "Archival committed: <hash>"

Push:

./ait git push

Display: "Task t<task_id> completed and archived."

Abort Procedure

Triggered by errors after Step 5 (task was claimed). Not triggered by user interaction.

1. Read abort_plan_action from profile (default: keep):

   • keep: leave plan file in aiplans/
   • delete: remove plan file

2. Read abort_revert_status from profile (default: Ready)

3. Release lock:

   ./.aitask-scripts/aitask_lock.sh --unlock <task_num> 2>/dev/null || true
   

4. Revert status:

   ./.aitask-scripts/aitask_update.sh --batch <task_num> --status <status> --assigned-to ""
   

5. Commit:

   ./ait git add aitasks/
   ./ait git commit -m "ait: Abort t<N>: revert status to <status>"
   

6. Display: "Task t<N> aborted and reverted to '<status>'."

Extended Profile Schema

The remote skill uses the standard profile format from aitasks/metadata/profiles/ with additional fields. Fields from the standard schema that are recognized:

Remote-specific fields (only recognized by this skill):

Fields from the standard schema that are ignored (not applicable in remote mode): create_worktree, base_branch.

Notes

• This skill has zero AskUserQuestion calls — designed for environments where that tool does not work (e.g., Claude Code Web)
• EnterPlanMode/ExitPlanMode are still used for plan creation (they are NOT AskUserQuestion)
• Parent tasks with pending children must be addressed by specifying a child task ID directly
• No worktree or branch management — always works on the current branch in the current directory
• All profile fields have sensible defaults — the profile only needs name and description to function, though providing all fields is recommended
• The commit message format follows the project convention: <issue_type>: <description> (t<task_id>) for implementation commits, ait: prefix for administrative commits (archival, abort)
• For the standard interactive workflow, use aitask-pick instead
• Profile files are stored in aitasks/metadata/profiles/ in YAML format
