plan-task

name	plan-task
description	Refine, parallelize, and verify a draft task specification into a fully planned implementation-ready task
argument-hint	Path to draft task file (e.g., ".specs/tasks/draft/add-validation.feature.md") [options]

Refine Task Workflow

Role

You are a task refinement orchestrator. Take a draft task file created by /add-task and refine it through a coordinated multi-agent workflow with quality gates after each phase.

Goal

This workflow command refines an existing draft task through:

1. Parallel Analysis - Research, codebase analysis, and business analysis in parallel
2. Architecture Synthesis - Combine findings into architectural overview
3. Decomposition - Break into implementation steps with risks
4. Parallelize - Reorganize steps for maximum parallel execution
5. Verify - Add LLM-as-Judge verification sections
6. Promote - Move refined task from draft/ to todo/

All phases include judge validation to prevent error propagation and ensure quality thresholds are met.

business analysis	2c	Refine description and create acceptance criteria
architecture synthesis	3	Synthesize research and analysis into architecture
decomposition	4	Break into implementation steps with risks
parallelize	5	Reorganize steps for parallel execution
verifications	6	Add LLM-as-Judge verification rubrics

Configuration Resolution

Parse $ARGUMENTS and resolve configuration as follows:

# Extract task file path (first positional argument, required)
TASK_FILE = first argument that is a file path (must exist in .specs/tasks/draft/)

# Parse alias flags first (they set multiple defaults)
if --fast present:
    THRESHOLD = 3.0
    MAX_ITERATIONS = 1
    INCLUDED_STAGES = ["business analysis", "decomposition", "verifications"]

if --one-shot present:
    INCLUDED_STAGES = ["business analysis", "decomposition"]
    SKIP_JUDGES = true

# Initialize defaults
THRESHOLD ?= --target-quality || 3.5
MAX_ITERATIONS ?= --max-iterations || 3
INCLUDED_STAGES ?= --included-stages || ["research", "codebase analysis", "business analysis", "architecture synthesis", "decomposition", "parallelize", "verifications"]
SKIP_STAGES = --skip || []
HUMAN_IN_THE_LOOP_PHASES = --human-in-the-loop || []
SKIP_JUDGES = --skip-judges || false
REFINE_MODE = --refine || false
CONTINUE_STAGE = null

if --continue [stage] present:
    CONTINUE_STAGE = stage or resolve from context

# Compute final active stages
ACTIVE_STAGES = INCLUDED_STAGES - SKIP_STAGES

Context Resolution for --continue

When --continue is used without explicit stage:

1. Stage Resolution:
   • Parse the task file for completion markers (e.g., [x] checkboxes)
   • Identify the last completed phase/judge
   • Resume from the next incomplete phase

Refine Mode Behavior (--refine)

When --refine is used:

1. Change Detection:

   • First check file status: git status --porcelain -- <TASK_FILE>
   • Compare current task file against last git commit: git diff HEAD -- <TASK_FILE>
     • This captures both staged and unstaged changes vs HEAD
   • If file is untracked or has no git history, compare against the original task structure
   • Identify which sections have been modified by the user
   • Look for // comment markers indicating user feedback/corrections

2. Top-to-Bottom Propagation:

   • Determine the earliest modified section (highest in document)
   • Re-run only stages that correspond to or come after the modified section
   • Earlier stages (above the modification) are preserved as-is

3. Section-to-Stage Mapping:

   Modified Section	Re-run From Stage
   Description / Acceptance Criteria	business analysis (Phase 2c)
   Architecture Overview	architecture synthesis (Phase 3)
   Implementation Process / Steps	decomposition (Phase 4)
   Parallelization / Dependencies	parallelize (Phase 5)
   Verification sections	verifications (Phase 6)

4. Refine Execution:

   • Skip research (2a) and codebase analysis (2b) unless explicitly requested
   • Pass user modifications and // comments as additional context to agents
   • Agents should incorporate user feedback while preserving unchanged content

5. Example:

   # User edited the Architecture Overview section
   /plan .specs/tasks/todo/my-task.feature.md --refine
   
   # Detects Architecture section changed → re-runs from Phase 3 onwards
   # Skips: research, codebase analysis, business analysis
   # Runs: architecture synthesis, decomposition, parallelize, verifications
   

Human-in-the-Loop Behavior

Human verification checkpoints occur:

1. Trigger Conditions:

   • After implementation + judge verification PASS for a phase in HUMAN_IN_THE_LOOP_PHASES
   • After implementation + judge + implementation retry (before the next judge retry)

2. At Checkpoint:

   • Display current phase results summary
   • Display generated artifacts with paths
   • Display judge score and feedback
   • Ask user: "Review phase output. Continue? [Y/n/feedback]"
   • If user provides feedback, incorporate into next iteration
   • If user says "n", pause workflow

3. Checkpoint Message Format:

   ---
   ## 🔍 Human Review Checkpoint - Phase X
   
   **Phase:** {phase name}
   **Judge Score:** {score}/{THRESHOLD} threshold
   **Status:** ✅ PASS / ⚠️ RETRY {n}/{MAX_ITERATIONS}
   
   **Artifacts:**
   - {artifact_path_1}
   - {artifact_path_2}
   
   **Judge Feedback:**
   {feedback summary}
   
   **Action Required:** Review the above artifacts and provide feedback or continue.
   
   > Continue? [Y/n/feedback]:

Usage Examples

# Refine a draft task with all stages
/plan .specs/tasks/draft/add-validation.feature.md

# Fast refinement with minimal stages
/plan .specs/tasks/draft/quick-fix.bug.md --fast

# Continue from a specific stage
/plan .specs/tasks/draft/complex-feature.feature.md --continue decomposition

# High-quality refinement with checkpoints
/plan .specs/tasks/draft/critical-api.feature.md --target-quality 4.5 --human-in-the-loop 2,3,4,5,6

# Incremental refinement after user edits (re-runs only affected stages)
/plan .specs/tasks/todo/my-task.feature.md --refine

Pre-Flight Checks

Before starting workflow:

1. Validate task file exists:

   • If REFINE_MODE is false: Check that TASK_FILE exists in .specs/tasks/draft/
   • If REFINE_MODE is true: Check that TASK_FILE exists in .specs/tasks/todo/ or .specs/tasks/draft/
   • If not found, show error and exit

2. Parse and display resolved configuration:

   ### Configuration
   
   | Setting | Value |
   |---------|-------|
   | **Task File** | {TASK_FILE} |
   | **Target Quality** | {THRESHOLD}/5.0 |
   | **Max Iterations** | {MAX_ITERATIONS} |
   | **Active Stages** | {ACTIVE_STAGES as comma-separated list} |
   | **Human Checkpoints** | Phase {HUMAN_IN_THE_LOOP_PHASES as comma-separated} |
   | **Skip Judges** | {SKIP_JUDGES} |
   | **Refine Mode** | {REFINE_MODE} |
   | **Continue From** | {CONTINUE_STAGE} or "Start" |
   

3. Handle --continue mode:

   If CONTINUE_STAGE is set:

   • Read the task file to get current state
   • Identify completed phases from task file content
   • Skip to CONTINUE_STAGE (or auto-detected next incomplete stage)
   • Pre-populate captured values from existing artifacts
   • Resume workflow from the appropriate phase

4. Handle --refine mode:

   If REFINE_MODE is true:

   • Check file status: git status --porcelain -- <TASK_FILE>
     • M (staged) or M (unstaged) or MM (both) → proceed with diff
     • ?? (untracked) → error: "File not tracked by git, cannot detect changes"
     • Empty output → no changes detected
   • Run git diff HEAD -- <TASK_FILE> to get all changes (staged + unstaged) vs last commit
   • Parse diff to identify modified sections
   • Collect any // comment markers as user feedback
   • Determine earliest modified section using Section-to-Stage Mapping
   • Set ACTIVE_STAGES to include only stages from the determined starting point onwards
   • Pass detected changes and user comments as additional context to agents
   • If no changes detected, inform user: "No changes detected in task file. Edit the file first, then run --refine." and exit

5. Extract task info from file:

   • Read task file to extract title and type from filename
   • Parse frontmatter for title and depends_on

6. Initialize workflow progress tracking using TodoWrite:

   Only include todos for phases in ACTIVE_STAGES. If continuing, mark completed phases as completed.

   {
     "todos": [
       {"content": "Ensure directories exist", "status": "pending", "activeForm": "Ensuring directories exist"},
       {"content": "Phase 2a: Research relevant resources and documentation", "status": "pending", "activeForm": "Researching resources"},
       {"content": "Judge 2a: PASS research quality (> {THRESHOLD})", "status": "pending", "activeForm": "Validating research"},
       {"content": "Phase 2b: Analyze codebase impact and affected files", "status": "pending", "activeForm": "Analyzing codebase impact"},
       {"content": "Judge 2b: PASS codebase analysis (> {THRESHOLD})", "status": "pending", "activeForm": "Validating codebase analysis"},
       {"content": "Phase 2c: Business analysis and acceptance criteria", "status": "pending", "activeForm": "Analyzing business requirements"},
       {"content": "Judge 2c: PASS business analysis (> {THRESHOLD})", "status": "pending", "activeForm": "Validating business analysis"},
       {"content": "Phase 3: Architecture synthesis from research and analysis", "status": "pending", "activeForm": "Synthesizing architecture"},
       {"content": "Judge 3: PASS architecture synthesis (> {THRESHOLD})", "status": "pending", "activeForm": "Validating architecture"},
       {"content": "Phase 4: Decompose into implementation steps", "status": "pending", "activeForm": "Decomposing into steps"},
       {"content": "Judge 4: PASS decomposition (> {THRESHOLD})", "status": "pending", "activeForm": "Validating decomposition"},
       {"content": "Phase 5: Parallelize implementation steps", "status": "pending", "activeForm": "Parallelizing steps"},
       {"content": "Judge 5: PASS parallelization (> {THRESHOLD})", "status": "pending", "activeForm": "Validating parallelization"},
       {"content": "Phase 6: Define verification rubrics", "status": "pending", "activeForm": "Defining verifications"},
       {"content": "Judge 6: PASS verifications (> {THRESHOLD})", "status": "pending", "activeForm": "Validating verifications"},
       {"content": "Move task to todo folder", "status": "pending", "activeForm": "Promoting task"},
       {"content": "Human checkpoint reviews", "status": "pending", "activeForm": "Awaiting human review"}
     ]
   }
   

   Note: Filter todos based on configuration:

   • If SKIP_JUDGES is true, omit ALL Judge todos (Judge 2a, 2b, 2c, 3, 4, 5, 6)
   • If research not in ACTIVE_STAGES, omit Phase 2a and Judge 2a todos
   • If codebase analysis not in ACTIVE_STAGES, omit Phase 2b and Judge 2b todos
   • If business analysis not in ACTIVE_STAGES, omit Phase 2c and Judge 2c todos
   • If architecture synthesis not in ACTIVE_STAGES, omit Phase 3 and Judge 3 todos
   • If decomposition not in ACTIVE_STAGES, omit Phase 4 and Judge 4 todos
   • If parallelize not in ACTIVE_STAGES, omit Phase 5 and Judge 5 todos
   • If verifications not in ACTIVE_STAGES, omit Phase 6 and Judge 6 todos
   • If HUMAN_IN_THE_LOOP_PHASES is empty, omit human checkpoint todo

7. Ensure directories exist:

   Run the folder creation script to create task directories and configure gitignore:

   bash ${CLAUDE_PLUGIN_ROOT}/scripts/create-folders.sh
   

   This creates:

   • .specs/tasks/draft/ - New tasks awaiting analysis
   • .specs/tasks/todo/ - Tasks ready to implement
   • .specs/tasks/in-progress/ - Currently being worked on
   • .specs/tasks/done/ - Completed tasks
   • .specs/scratchpad/ - Temporary working files (gitignored)
   • .specs/analysis/ - Codebase impact analysis files
   • .claude/skills/ - Reusable skill documents

Update each todo to in_progress when starting a phase and completed when judge passes.

CRITICAL

• Do not mark PASS for any judge if it did not pass the rubric. Retry the judge after each implementation change till it passes the check!
• Do not read task files in .claude or .specs directories, your job is orchestrate agents that will do the work, not do it by yourself!
• Use THRESHOLD (default 3.5) for all judge pass/fail decisions, not hardcoded values!
• Use MAX_ITERATIONS (default 3) for retry limits, not hardcoded values!
• After MAX_ITERATIONS reached: PROCEED to next stage automatically - do NOT ask user unless phase is in HUMAN_IN_THE_LOOP_PHASES!
• Skip phases not in ACTIVE_STAGES entirely - do not launch agents for excluded stages!
• Trigger human-in-the-loop checkpoints ONLY after phases in HUMAN_IN_THE_LOOP_PHASES!
• If SKIP_JUDGES is true: Skip ALL judge validation - proceed directly to next phase after each implementation phase completes!
• Task file must exist in .specs/tasks/draft/ before running this command (unless --refine mode)!
• If REFINE_MODE is true: Detect changes via git diff, skip unchanged stages, pass user feedback to agents!

Execution & Evaluation Rules

• Use foreground agents only: Do not use background agents. Launch parallel agents when possible. Background agents constantly run in permissions issues and other errors.

Relaunch judge till you get valid results, of following happens:

• Reject Long Reports: If an agent returns a very long report instead of using the scratchpad as requested, reject the result. This indicates the agent failed to follow the "use scratchpad" instruction.
• Judge Score 5.0 is a Hallucination: If a judge returns a score of 5.0/5.0, treat it as a hallucination or lazy evaluation. Reject it and re-run the judge. Perfect scores are practically impossible in this rigorous framework.
• Reject Missing Scores: If a judge report is missing the numerical score, reject it. This indicates the judge failed to read or follow the rubric instructions.

Workflow Execution

You MUST launch for each step a separate agent, instead of performing all steps yourself.

CRITICAL: For each agent you MUST:

1. Use the Agent type and Model specified in the step
2. Provide the task file path and user input as context
3. Provide the value of ${CLAUDE_PLUGIN_ROOT} so agents can resolve paths like @${CLAUDE_PLUGIN_ROOT}/scripts/create-scratchpad.sh
4. Require agent to implement exactly that step, not more, not less
5. After each sub-phase, launch a judge agent to validate quality before proceeding

Complete Workflow Overview

Note: Phases not in ACTIVE_STAGES are skipped. If SKIP_JUDGES is true, all judge steps are skipped entirely. Human checkpoints (🔍) occur after phases in HUMAN_IN_THE_LOOP_PHASES.

Phase 2: Parallel Analysis

Phase 2 launches three analysis phases in parallel, each with its own judge validation.

Phase 2a/2b/2c: Parallel Sub-Phases

Launch these three phases in parallel immediately:

---

Phase 2a: Research

Model: sonnet Agent: sdd:researcher Depends on: Task file exists Purpose: Gather relevant resources, documentation, libraries, and prior art. Creates or updates a reusable skill.

Launch agent:

• Prompt:

  CLAUDE_PLUGIN_ROOT=${CLAUDE_PLUGIN_ROOT}
  
  Task File: <TASK_FILE>
  Task Title: <title from task file>
  
  CRITICAL: DO NOT OUTPUT YOUR RESEARCH, ONLY CREATE THE SCRATCHPAD AND SKILL FILE.
  

Capture:

• Skill file path (e.g., .claude/skills/<skill-name>/SKILL.md)
• Skill action (Created new / Updated existing)
• Scratchpad file path (e.g., .specs/scratchpad/<hex-id>.md)
• Number of resources gathered
• Key recommendation summary

CRITICAL: If expected files not created, launch the agent again with the same prompt.

---

Phase 2b: Codebase Impact Analysis

Model: sonnet Agent: sdd:code-explorer Depends on: Task file exists Purpose: Identify affected files, interfaces, and integration points

2. Update any references in research and analysis files if needed

---

Completion

After all executed phases and judges complete:

1. Use git tool to stage the task file, skill file, analysis file, and scratchpad files (only those that were created)
2. Summarize the workflow results and output to user:

### Task Refined

| Property | Value |
|----------|-------|
| **Original File** | `<original TASK_FILE path>` |
| **Final Location** | `.specs/tasks/todo/<filename>` (ready for implementation) |
| **Title** | `<task title>` |
| **Type** | `<feature/bug/refactor/test/docs/chore/ci>` (from filename) |
| **Skill** | `<skill file path or "Skipped">` |
| **Skill Action** | `<Created new / Updated existing / Skipped>` |
| **Analysis** | `<analysis file path or "Skipped">` |
| **Scratchpad** | `<scratchpad file path>` |
| **Implementation Steps** | `<count or "N/A">` |

- ⚠️ PROCEEDED (max iter) - Score < THRESHOLD but MAX_ITERATIONS reached, proceeded anyway
- ⏭️ SKIPPED - Stage not in ACTIVE_STAGES

### Artifacts Generated

.claude/ └── skills/ └── / └── SKILL.md # Reusable skill document (if research stage ran)

.specs/ ├── tasks/ │ ├── draft/ # Draft tasks (source - now empty for this task) │ ├── todo/ │ │ └── ..md # Complete task specification (ready for implementation) │ ├── in-progress/ # Tasks being implemented (empty) │ └── done/ # Completed tasks (empty) ├── analysis/ │ └── analysis-.md # Codebase impact analysis (if codebase analysis stage ran) └── scratchpad/ └── .md # Architecture thinking scratchpad

### Task Status Management

Task status is managed by folder location:
- `draft/` - Tasks created but not yet refined
- `todo/` - Tasks ready for implementation
- `in-progress/` - Tasks currently being worked on
- `done/` - Completed tasks

### Next Steps

1. Review task: `.specs/tasks/todo/<filename>`
   - Edit the task file directly to make corrections
   - Add `//` comments to lines that need clarification or changes
   - Run `/plan` again with `--refine` to incorporate your feedback — it detects changes against git and propagates updates **top-to-bottom** (editing a section only affects sections below it, not above)
2. If everything is fine, begin implementation: `/implement` (will auto-select the task from todo/)

---

Error Handling

Phase Agent Failure (Exception/Crash)

If any phase agent fails unexpectedly:

1. Report the failure with agent output
2. Ask clarification questions from user that can help resolve the issue
3. Launch the phase agent again with list of questions and answers to resolve the issue

Judge Returns FAIL

If any judge returns FAIL (score < THRESHOLD):

1. Automatic retry: Re-launch the phase agent with judge feedback
2. Human-in-the-loop check: If phase is in HUMAN_IN_THE_LOOP_PHASES, trigger human checkpoint before the next judge retry (after implementation retry but before re-judging)
3. After MAX_ITERATIONS reached: Proceed to next stage automatically (do NOT ask user unless --human-in-the-loop includes this phase)
4. Log warning in completion summary: ⚠️ Phase X did not pass quality threshold (X.X/THRESHOLD) after MAX_ITERATIONS iterations

Retry Flow

Implementation → Judge FAIL → Implementation Retry → Judge Retry
                                                          ↓

                                          ↓
                              MAX_ITERATIONS reached → Proceed to next stage (with warning)

Retry Flow with Human-in-the-Loop

When phase is in HUMAN_IN_THE_LOOP_PHASES:

Implementation → Judge FAIL → Implementation Retry
                                    ↓
                    🔍 Human Checkpoint (optional feedback)
                                    ↓

                                                    ↓
                              MAX_ITERATIONS → 🔍 Final Human Checkpoint
                                                    ↓
                                    User confirms → Proceed to next stage
