description	Implement a task with automated LLM-as-Judge verification for critical steps
argument-hint	Task file [options] (e.g., "add-validation.feature.md --continue --human-in-the-loop")

Implement Task with Verification

Your job is to implement solution in best quality using task specification and sub-agents. You MUST NOT stop until it critically neccesary or you are done! Avoid asking questions until it is critically neccesary! Launch implementation agent, judges, iterate till issues are fixed and then move to next step!

Execute task implementation steps with automated quality verification using LLM-as-Judge for critical artifacts.

Command Arguments

Parse the following arguments from $ARGUMENTS:

Argument Definitions

Argument	Format	Default	Description
task-file	Path or filename	Auto-detect	Task file name or path (e.g., add-validation.feature.md)
--continue	--continue	None	Continue implementation from last completed step. Launches judge first to verify state, then iterates with implementation agent.
--refine	--refine	false	Incremental refinement mode - detect changes against git and re-implement only affected steps (from modified step onwards).
--human-in-the-loop	--human-in-the-loop [step1,step2,...]	None	Steps after which to pause for human verification. If no steps specified, pauses after every step.
--target-quality	--target-quality X.X or --target-quality X.X,Y.Y	4.0 (standard) / 4.5 (critical)	Target threshold value (out of 5.0). Single value sets both. Two comma-separated values set standard,critical.
--max-iterations	--max-iterations N	3	Maximum fix→verify cycles per step. Default is 3 iterations. Set to unlimited for no limit.
--skip-judges	--skip-judges	false	Skip all judge validation checks - steps proceed without quality gates.

Configuration Resolution

Parse $ARGUMENTS and resolve configuration as follows:

# Extract task file (first positional argument, optional - auto-detect if not provided)
TASK_FILE = first argument that is a file path or filename

# Parse --target-quality (supports single value or two comma-separated values)
if --target-quality has single value X.X:
    THRESHOLD_FOR_STANDARD_COMPONENTS = X.X
    THRESHOLD_FOR_CRITICAL_COMPONENTS = X.X
elif --target-quality has two values X.X,Y.Y:
    THRESHOLD_FOR_STANDARD_COMPONENTS = X.X
    THRESHOLD_FOR_CRITICAL_COMPONENTS = Y.Y
else:
    THRESHOLD_FOR_STANDARD_COMPONENTS = 4.0  # default
    THRESHOLD_FOR_CRITICAL_COMPONENTS = 4.5  # default

# Initialize other defaults
MAX_ITERATIONS = --max-iterations || 3  # default is 3 iterations 
HUMAN_IN_THE_LOOP_STEPS = --human-in-the-loop || [] (empty = none, "*" = all)
SKIP_JUDGES = --skip-judges || false
REFINE_MODE = --refine || false
CONTINUE_MODE = --continue || false

# Special handling for --human-in-the-loop without step list
if --human-in-the-loop present without step numbers:
    HUMAN_IN_THE_LOOP_STEPS = "*" (all steps)

Context Resolution for --continue

When --continue is used:

1. Step Resolution:

   • Parse the task file for [DONE] markers on step titles
   • Identify the last incompleted step
   • Launch judge to verify the last INCOMPLETE step's artifacts
   • If judge PASS: Mark step as done and resume from the next step
   • If judge FAIL: Re-implement the step and iterate until PASS

2. State Recovery:

   • Check task file location (in-progress/, todo/, done/)
   • If in todo/, move to in-progress/ before continuing
   • Pre-populate captured values from existing artifacts

Refine Mode Behavior (--refine)

When --refine is used, it detects changes to project files (not the task file) and maps them to implementation steps to determine what needs re-verification.

1. Detect Changed Project Files:

   First, determine what to compare against based on git state:

   # Check for staged changes
   STAGED=$(git diff --cached --name-only)
   
   # Check for unstaged changes
   UNSTAGED=$(git diff --name-only)
   

   Comparison logic:

   Staged	Unstaged	Compare Against	Command
   Yes	Yes	Staged (unstaged only)	git diff --name-only
   Yes	No	Last commit	git diff HEAD --name-only
   No	Yes	Last commit	git diff HEAD --name-only
   No	No	No changes	Exit with message

   • If both staged AND unstaged: Compare working directory vs staging area (unstaged changes only)
   • If only staged OR only unstaged: Compare against last commit
   • This ensures refine operates on the most recent work in progress

2. Map Changes to Implementation Steps:

   • Read the task file to get the list of implementation steps
   • For each changed file, determine which step created/modified it:
     • Check step's "Expected Output" section for file paths
     • Check step's subtasks for file references
     • Check step's artifacts in #### Verification section
   • Build a mapping: {changed_file → step_number}

3. Determine Affected Steps:

   • Find all steps that have associated changed files
   • The earliest affected step is the starting point
   • All steps from that point onwards need re-verification
   • Earlier steps (unaffected) are preserved as-is

4. Refine Execution:

   • For each affected step (in order):
     • Launch judge agent to verify the step's artifacts (including user's changes)
     • If judge PASS: Mark step done, proceed to next
     • If judge FAIL: Launch implementation agent with user's changes as context, then re-verify
   • User's manual fixes are preserved - implementation agent should build upon them, not overwrite

5. Example:

   # User manually fixed src/validation/validation.service.ts
   # (This file was created in Step 2)
   
   /implement my-task.feature.md --refine
   
   # Detects: src/validation/validation.service.ts modified
   # Maps to: Step 2 (Create ValidationService)
   # Action: Launch judge for Step 2
   #   - If PASS: User's fix is good, proceed to Step 3
   #   - If FAIL: Implementation agent align rest of the code with user changes, without overwriting user's changes
   # Continues: Step 3, Step 4... (re-verify all subsequent steps)
   

6. Multiple Files Changed:

   # User edited files from Step 2 AND Step 4
   
   /implement my-task.feature.md --refine
   
   # Detects: Files from Step 2 and Step 4 modified
   # Earliest affected: Step 2
   # Re-verifies: Step 2, Step 3, Step 4, Step 5...
   # (Step 3 re-verified even though no direct changes, because it depends on Step 2)
   

7. Staged vs Unstaged Changes:

   # Scenario: User staged some changes, then made more edits
   # Staged: src/validation/validation.service.ts (git add done)
   # Unstaged: src/validation/validators/email.validator.ts (still editing)
   
   /implement my-task.feature.md --refine
   
   # Detects: Both staged AND unstaged changes exist
   # Mode: Compares unstaged only (working dir vs staging)
   # Only email.validator.ts is considered for refine
   # Staged changes are preserved, not re-verified
   
   # --
   
   # Scenario: User only has staged changes (ready to commit)
   # Staged: src/validation/validation.service.ts
   # Unstaged: none
   
   /implement my-task.feature.md --refine
   
   # Detects: Only staged changes
   # Mode: Compares against last commit
   # validation.service.ts changes are verified
   

Human-in-the-Loop Behavior

Human verification checkpoints occur:

1. Trigger Conditions:

   • After implementation + judge verification PASS for a step in HUMAN_IN_THE_LOOP_STEPS
   • After implementation + judge + implementation retry (before the next judge retry)
   • If HUMAN_IN_THE_LOOP_STEPS is "*", triggers after every step

2. At Checkpoint:

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

3. Checkpoint Message Format:

   ---
   ## 🔍 Human Review Checkpoint - Step X
   
   **Step:** {step title}
   **Step Type:** {standard/critical}
   **Judge Score:** {score}/{threshold for step type} threshold
   **Status:** ✅ PASS / 🔄 ITERATING (attempt {n})
   
   **Artifacts Created/Modified:**
   - {artifact_path_1}
   - {artifact_path_2}
   
   **Judge Feedback:**
   {feedback summary}
   
   **Action Required:** Review the above artifacts and provide feedback or continue.

Task Selection and Status Management

Task Status Folders

Task status is managed by folder location:

• .memory-bank/specs/tasks/todo/ - Tasks waiting to be implemented
• .memory-bank/specs/tasks/in-progress/ - Tasks currently being worked on
• .memory-bank/specs/tasks/done/ - Completed tasks

Status Transitions

When	Action
Start implementation	Move task from todo/ to in-progress/
Final verification PASS	Move task from in-progress/ to done/
Implementation failure (user aborts)	Keep in in-progress/

---

CRITICAL: You Are an ORCHESTRATOR ONLY

Your role is DISPATCH and AGGREGATE. You do NOT do the work.

Properly build context of sub agents!

CRITICAL: For each sub-agent (implementation and evaluation), you need to provide:

• Task file path
• Step number
• Item number (if applicable)
• Artifact path (if applicable)
• Value of ${CLAUDE_PLUGIN_ROOT} so agents can resolve paths like @${CLAUDE_PLUGIN_ROOT}/scripts/create-scratchpad.sh

What You DO

• Read the task file ONCE (Phase 1 only)
• Launch sub-agents via Task tool
• Receive reports from sub-agents
• Mark stages complete after judge confirmation
• Aggregate results and report to user

What You NEVER Do

Prohibited Action	Why	What To Do Instead
Read implementation outputs	Context bloat → command loss	Sub-agent reports what it created
Read reference files	Sub-agent's job to understand patterns	Include path in sub-agent prompt
Read artifacts to "check" them	Context bloat → forget verifications	Launch judge agent
Evaluate code quality yourself	Not your job, causes forgetting	Launch judge agent
Skip verification "because simple"	ALL verifications are mandatory	Launch judge agent anyway

Anti-Rationalization Rules

If you think: "I should read this file to understand what was created" → STOP. The sub-agent's report tells you what was created. Use that information.

If you think: "I'll quickly verify this looks correct" → STOP. Launch a judge agent. That's not your job.

If you think: "This is too simple to need verification" → STOP. If the task specifies verification, launch the judge. No exceptions.

If you think: "I need to read the reference file to write a good prompt" → STOP. Put the reference file PATH in the sub-agent prompt. Sub-agent reads it.

Why This Matters

Orchestrators who read files themselves = context overflow = command loss = forgotten steps. Every time.

Orchestrators who "quickly verify" = skip judge agents = quality collapse = failed artifacts.

Your context window is precious. Protect it. Delegate everything.

CRITICAL

Configuration Rules

• Use THRESHOLD_FOR_STANDARD_COMPONENTS (default 4.0) for standard steps!
• Use THRESHOLD_FOR_CRITICAL_COMPONENTS (default 4.5) for steps marked as critical in task file!
• Default is 3 iterations - stop after 3 fix→verify cycles and proceed to next step (with warning)!
• If MAX_ITERATIONS is set to unlimited: Iterate until quality threshold is met (no limit)
• Trigger human-in-the-loop checkpoints ONLY after steps in HUMAN_IN_THE_LOOP_STEPS (or all steps if "*")!
• If SKIP_JUDGES is true: Skip ALL judge validation - proceed directly to next step after each implementation completes!
• If CONTINUE_MODE is true: Skip to RESUME_FROM_STEP - do not re-implement already completed steps!
• If REFINE_MODE is true: Detect changed project files, map to steps, re-verify from REFINE_FROM_STEP - preserve user's fixes!

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.

Phase 0: Parse User Input and Select Task

Parse user input to get the task file path and arguments.

Step 0.1: Resolve Task File

If $ARGUMENTS is empty or only contains flags:

1. Check in-progress folder first:

   ls .memory-bank/specs/tasks/in-progress/*.md 2>/dev/null
   

   • If exactly 1 file → Set $TASK_FILE to that file, $TASK_FOLDER to in-progress
   • If multiple files → List them and ask user: "Multiple tasks in progress. Which one to continue?"
   • If no files → Continue to step 2

2. Check todo folder:

   ls .memory-bank/specs/tasks/todo/*.md 2>/dev/null
   

   • If exactly 1 file → Set $TASK_FILE to that file, $TASK_FOLDER to todo
   • If multiple files → List them and ask user: "Multiple tasks in todo. Which one to implement?"
   • If no files → Report "No tasks available. Create one with /add-task first." and STOP

If $ARGUMENTS contains a task file name:

1. Search for the file in order: in-progress/ → todo/ → done/
2. Set $TASK_FILE and $TASK_FOLDER accordingly
3. If not found, report error and STOP

Step 0.2: Move to In-Progress (if needed)

If task is in todo/ folder:

git mv .memory-bank/specs/tasks/todo/$TASK_FILE .memory-bank/specs/tasks/in-progress/
# Fallback if git not available: mv .memory-bank/specs/tasks/todo/$TASK_FILE .memory-bank/specs/tasks/in-progress/

Update $TASK_PATH to .memory-bank/specs/tasks/in-progress/$TASK_FILE

If task is already in in-progress/: Set $TASK_PATH to .memory-bank/specs/tasks/in-progress/$TASK_FILE

Step 0.3: Parse Flags and Initialize Configuration

Parse all flags from $ARGUMENTS and initialize configuration. Display resolved configuration:

### Configuration

| Setting | Value |
|---------|-------|
| **Task File** | {TASK_PATH} |
| **Standard Components Threshold** | {THRESHOLD_FOR_STANDARD_COMPONENTS}/5.0 |
| **Critical Components Threshold** | {THRESHOLD_FOR_CRITICAL_COMPONENTS}/5.0 |
| **Max Iterations** | {MAX_ITERATIONS or "3"} |
| **Human Checkpoints** | {HUMAN_IN_THE_LOOP_STEPS as comma-separated or "All steps" or "None"} |
| **Skip Judges** | {SKIP_JUDGES} |
| **Continue Mode** | {CONTINUE_MODE} |
| **Refine Mode** | {REFINE_MODE} |

Step 0.4: Handle Continue Mode

If CONTINUE_MODE is true:

1. Identify Last Completed Step:

   • Parse task file for [DONE] markers on step titles
   • Find the highest step number marked [DONE]
   • Set LAST_COMPLETED_STEP to that number (or 0 if none)

2. Verify Last Completed Step (if any):

   • If LAST_COMPLETED_STEP > 0:
     • Launch judge agent to verify the artifacts from that step
     • If judge PASS: Set RESUME_FROM_STEP = LAST_COMPLETED_STEP + 1
     • If judge FAIL: Set RESUME_FROM_STEP = LAST_COMPLETED_STEP (re-implement)

3. Skip to Resume Point:

   • In Phase 2, skip all steps before RESUME_FROM_STEP
   • Continue execution from RESUME_FROM_STEP

Step 0.5: Handle Refine Mode

If REFINE_MODE is true:

1. Detect Changed Project Files:

   # Check for staged and unstaged changes
   STAGED=$(git diff --cached --name-only)
   UNSTAGED=$(git diff --name-only)
   

   Determine comparison mode:

   if STAGED is not empty AND UNSTAGED is not empty:
       # Both staged and unstaged - use unstaged only
       CHANGED_FILES = git diff --name-only  # working dir vs staging
       COMPARISON_MODE = "unstaged_only"
   elif STAGED is not empty OR UNSTAGED is not empty:
       # Only one type - compare against last commit
       CHANGED_FILES = git diff HEAD --name-only
       COMPARISON_MODE = "vs_last_commit"
   else:
       # No changes
       Report: "No project changes detected. Make edits first, then run --refine."
       Exit
   

2. Load Task File and Extract Step→File Mapping:

   • Read the task file to get implementation steps
   • For each step, extract the files it creates/modifies from:
     • "Expected Output" sections
     • Subtask descriptions mentioning file paths
     • #### Verification artifact paths
   • Build mapping: STEP_FILE_MAP = {step_number → [file_paths]}

3. Map Changed Files to Steps:

   AFFECTED_STEPS = []
   for each changed_file:
       for step_number, file_list in STEP_FILE_MAP:
           if changed_file matches any path in file_list:
               AFFECTED_STEPS.append(step_number)
   

   • If no steps matched: "Changed files don't map to any implementation step. Verify manually."

4. Determine Refine Scope:

   • REFINE_FROM_STEP = min(AFFECTED_STEPS) # earliest affected step
   • All steps from REFINE_FROM_STEP onwards need re-verification
   • Steps before REFINE_FROM_STEP are preserved as-is

5. Store Changed Files Context:

   • CHANGED_FILES = list of changed file paths
   • USER_CHANGES_CONTEXT = git diff output for affected files
   • Pass this context to judge and implementation agents
   • Agents should build upon user's fixes, not overwrite them

Phase 1: Load and Analyze Task

This is the ONLY phase where you read a file.

Step 1.1: Load Task Details

Read the task file ONCE:

Read $TASK_PATH

After this read, you MUST NOT read any other files for the rest of execution.

Step 1.2: Identify Implementation Steps

Parse the ## Implementation Process section:

• List all steps with dependencies
• Identify which steps have Parallel with: annotations
• Classify each step's verification needs from #### Verification sections:

Verification Level	When to Use	Judge Configuration
None	Simple operations (mkdir, delete)	Skip verification
Single Judge	Non-critical artifacts	1 judge, threshold 4.0/5.0
Panel of 2 Judges	Critical artifacts	2 judges, median voting, threshold 4.5/5.0
Per-Item Judges	Multiple similar items	1 judge per item, parallel

Step 1.3: Create Todo List

Create TodoWrite with all implementation steps, marking verification requirements:

{
  "todos": [
    {"content": "Step 1: [Title] - [Verification Level]", "status": "pending", "activeForm": "Implementing Step 1"},
    {"content": "Step 2: [Title] - [Verification Level]", "status": "pending", "activeForm": "Implementing Step 2"}
  ]
}

---

Phase 2: Execute Implementation Steps

For each step in dependency order:

Pattern A: Simple Step (No Verification)

1. Launch Developer Agent:

Use Task tool with:

• Agent Type: sdd:developer
• Model: As specified in step or opus by default
• Description: "Implement Step [N]: [Title]"
• Prompt:

Implement Step [N]: [Step Title]

Task File: $TASK_PATH
Step Number: [N]

Your task:
- Execute ONLY Step [N]: [Step Title]
- Do NOT execute any other steps
- Follow the Expected Output and Success Criteria exactly

When complete, report:
1. What files were created/modified (paths)
2. Confirmation that success criteria are met
3. Any issues encountered

2. Use Agent's Report (No Verification)

• Agent reports what was created → Use this information
• DO NOT read the created files yourself
• This pattern has NO verification (simple operations)

3. Mark Step Complete

• Update task file:
  • Mark step title with [DONE] (e.g., ### Step 1: Setup [DONE])
  • Mark step's subtasks as [X] complete
• Update todo to completed

---

Pattern B: Critical Step (Panel of 2 Evaluations)

1. Launch Developer Agent:

Use Task tool with:

• Agent Type: sdd:developer
• Model: As specified in step or opus by default
• Description: "Implement Step [N]: [Title]"
• Prompt:

Implement Step [N]: [Step Title]

Task File: $TASK_PATH
Step Number: [N]

Your task:
- Execute ONLY Step [N]: [Step Title]
- Do NOT execute any other steps
- Follow the Expected Output and Success Criteria exactly

When complete, report:
1. What files were created/modified (paths)
2. Confirmation of completion
3. Self-critique summary

2. Wait for Completion

• Receive the agent's report
• Note the artifact path(s) from the report
• DO NOT read the artifact yourself

3. Launch 2 Evaluation Agents in Parallel (MANDATORY):

⚠️ MANDATORY: This pattern requires launching evaluation agents. You MUST launch these evaluations. Do NOT skip. Do NOT verify yourself.

Use sdd:developer agent type for evaluations

Evaluation 1 & 2 (launch both in parallel with same prompt structure):

CLAUDE_PLUGIN_ROOT=${CLAUDE_PLUGIN_ROOT}

Read @${CLAUDE_PLUGIN_ROOT}/prompts/judge.md for evaluation methodology.

Evaluate artifact at: [artifact_path from implementation agent report]

**Chain-of-Thought Requirement:** Justification MUST be provided BEFORE score for each criterion.

Rubric:
[paste rubric table from #### Verification section]

Context:
- Read $TASK_PATH
- Verify Step [N] ONLY: [Step Title]
- Threshold: [from #### Verification section]
- Reference pattern: [if specified in #### Verification section]

You can verify the artifact works - run tests, check imports, validate syntax.

Return: scores per criterion with evidence, overall weighted score, PASS/FAIL, improvements if FAIL.

4. Aggregate Results:

• Calculate median score per criterion
• Flag high-variance criteria (std > 1.0)
• Pass if median overall ≥ threshold

5. Determine Threshold:

• Check if step is marked as critical in task file (in #### Verification section or step metadata)
• If critical: use THRESHOLD_FOR_CRITICAL_COMPONENTS
• If standard: use THRESHOLD_FOR_STANDARD_COMPONENTS

6. On FAIL: Iterate Until PASS (max 3 iterations by default)

• Present issues to implementation agent with judge feedback
• Re-implement with judge feedback incorporated (align code with requirements, preserve user's changes if in refine mode)
• Re-verify with judge
• Iterate until PASS - continue fix → verify cycle until quality threshold is met or max iterations reached
• If MAX_ITERATIONS reached (default 3):
  • Log warning: "Step [N] did not pass after {MAX_ITERATIONS} iterations"
  • Proceed to next step (do not block indefinitely)

7. On PASS: Mark Step Complete

• Update task file:
  • Mark step title with [DONE] (e.g., ### Step 2: Create Service [DONE])
  • Mark step's subtasks as [X] complete
• Update todo to completed
• Record judge scores in tracking

8. Human-in-the-Loop Checkpoint (if applicable):

Only after step PASSES, if step number is in HUMAN_IN_THE_LOOP_STEPS (or HUMAN_IN_THE_LOOP_STEPS == "*"):

---
## 🔍 Human Review Checkpoint - Step [N]

**Step:** [Step Title]
**Judge Score:** [score]/[threshold for step type] threshold
**Status:** ✅ PASS

**Artifacts Created/Modified:**
- [artifact_path_1]
- [artifact_path_2]

**Judge Feedback:**
[feedback summary from judges]

**Action Required:** Review the above artifacts and provide feedback or continue.

> Continue? [Y/n/feedback]:
---

• If user provides feedback: Store for next step or re-implement current step with feedback
• If user says "n": Pause workflow, report current progress
• If user says "Y" or continues: Proceed to next step

---

Pattern C: Multi-Item Step (Per-Item Evaluations)

For steps that create multiple similar items:

1. Launch Developer Agents in Parallel (one per item):

Use Task tool for EACH item (launch all in parallel):

• Agent Type: sdd:developer
• Model: As specified or opus by default
• Description: "Implement Step [N], Item: [Name]"
• Prompt:

Implement Step [N], Item: [Item Name]

Task File: $TASK_PATH
Step Number: [N]
Item: [Item Name]

Your task:
- Create ONLY [item_name] from Step [N]
- Do NOT create other items or steps
- Follow the Expected Output and Success Criteria exactly

When complete, report:
1. File path created
2. Confirmation of completion
3. Self-critique summary

2. Wait for All Completions

• Collect all agent reports
• Note all artifact paths
• DO NOT read any of the created files yourself

3. Launch Evaluation Agents in Parallel (one per item)

⚠️ MANDATORY: Launch evaluation agents. Do NOT skip. Do NOT verify yourself.

Use sdd:developer agent type for evaluations

For each item:

CLAUDE_PLUGIN_ROOT=${CLAUDE_PLUGIN_ROOT}

Read @${CLAUDE_PLUGIN_ROOT}/prompts/judge.md for evaluation methodology.

Evaluate artifact at: [item_path from implementation agent report]

**Chain-of-Thought Requirement:** Justification MUST be provided BEFORE score for each criterion.

Rubric:
[paste rubric from #### Verification section]

Context:
- Read $TASK_PATH
- Verify Step [N]: [Step Title]
- Verify ONLY this Item: [Item Name]
- Threshold: [from #### Verification section]

You can verify the artifact works - run tests, check syntax, confirm dependencies.

Return: scores with evidence, overall score, PASS/FAIL, improvements if FAIL.

4. Collect All Results

5. Report Aggregate:

• Items passed: X/Y
• Items needing revision: [list with specific issues]

6. Determine Threshold:

• Check if step is marked as critical in task file (in #### Verification section or step metadata)
• If critical: use THRESHOLD_FOR_CRITICAL_COMPONENTS
• If standard: use THRESHOLD_FOR_STANDARD_COMPONENTS

7. If Any FAIL: Iterate Until ALL PASS

• Present failing items with judge feedback to implementation agent
• Re-implement only failing items with feedback incorporated (preserve user's changes if in refine mode)
• Re-verify failing items with judge
• Iterate until ALL PASS - continue fix → verify cycle until all items meet quality threshold or max iterations reached
• If MAX_ITERATIONS reached (default 3):
  • Log warning: "Step [N] has {X} items that did not pass after {MAX_ITERATIONS} iterations"
  • Proceed to next step (do not block indefinitely)

8. On ALL PASS: Mark Step Complete

• Update task file:
  • Mark step title with [DONE] (e.g., ### Step 3: Create Items [DONE])
  • Mark step's subtasks as [X] complete
• Update todo to completed
• Record pass rate in tracking

9. Human-in-the-Loop Checkpoint (if applicable):

Only after ALL items PASS, if step number is in HUMAN_IN_THE_LOOP_STEPS (or HUMAN_IN_THE_LOOP_STEPS == "*"):

---
## 🔍 Human Review Checkpoint - Step [N]

**Step:** [Step Title]
**Items Passed:** X/Y
**Status:** ✅ ALL PASS

**Artifacts Created:**
- [item_1_path]
- [item_2_path]
- ...

**Action Required:** Review the above artifacts and provide feedback or continue.

> Continue? [Y/n/feedback]:
---

• If user provides feedback: Store for next step or re-implement items with feedback
• If user says "n": Pause workflow, report current progress
• If user says "Y" or continues: Proceed to next step

---

⚠️ CHECKPOINT: Before Proceeding to Final Verification

Before moving to final verification, verify you followed the rules:

• Did you launch sdd:developer agents for ALL implementations?
• Did you launch evaluation agents for ALL verifications?
• Did you mark steps complete ONLY after judge PASS?
• Did you avoid reading ANY artifact files yourself?

If you read files other than the task file, you are doing it wrong. STOP and restart.

---

Phase 3: Final Verification

After all implementation steps are complete, verify the task meets all Definition of Done criteria.

Step 3.1: Launch Definition of Done Verification

Use Task tool with:

• Agent Type: sdd:developer
• Model: opus
• Description: "Verify Definition of Done"
• Prompt:

CLAUDE_PLUGIN_ROOT=${CLAUDE_PLUGIN_ROOT}

Verify all Definition of Done items in the task file.

Task File: $TASK_PATH

Your task:
1. Read the task file and locate the "## Definition of Done (Task Level)" section
2. Go through each checkbox item one by one
3. For each item, verify if it passes by:
   - Running appropriate tests (unit tests, E2E tests)
   - Checking build/compilation status
   - Verifying file existence and correctness
   - Checking code patterns and linting
4. You MUST mark each item in task file that passed verification with `[X]`
5. Return a structured report:
- List ALL Definition of Done items
- Status for each:
   - ✅ PASS - if the item is complete and verified
   - ❌ FAIL - if the item fails verification, with specific reason why
   - ⚠️ BLOCKED - if the item cannot be verified due to a blocker
- Evidence for each status
- Specific issues for any failures
- Overall pass rate

Be thorough - check everything the task requires.

Step 3.2: Review Verification Results

• Receive the verification report
• Note which items PASS and which FAIL
• if judge report that all items PASS, you MUST read end of task file to verify that all DoD items are marked with [X]

Step 3.3: Fix Failing Items (If Any)

If any Definition of Done items FAIL:

1. Launch Developer Agent for Each Failing Item:

Fix Definition of Done item: [Item Description]

Task File: $TASK_PATH

Current Status:
[paste failure details from verification report]

Your task:
1. Fix the specific issue identified
2. Verify the fix resolves the problem
3. Ensure no regressions (all tests still pass)

Return:
- What was fixed
- Confirmation the item now passes
- Any related changes made

2. Re-verify After Fixes:

Launch the verification agent again (Step 3.1) to confirm all items now PASS.

3. Iterate if Needed:

Repeat fix → verify cycle until all Definition of Done items PASS.

---

Phase 4: Move Task to Done

Once ALL Definition of Done items PASS, move the task to the done folder.

Step 4.1: Verify Completion

Confirm all Definition of Done items are marked complete in the task file.

Step 4.2: Move Task

# Extract just the filename from $TASK_PATH
TASK_FILENAME=$(basename $TASK_PATH)

# Move from in-progress to done
git mv .memory-bank/specs/tasks/in-progress/$TASK_FILENAME .memory-bank/specs/tasks/done/
# Fallback if git not available: mv .memory-bank/specs/tasks/in-progress/$TASK_FILENAME .memory-bank/specs/tasks/done/

---

Phase 5: Aggregation and Reporting

Panel Voting Algorithm

When using 2+ evaluations, follow these manual computation steps:

• Think in steps, output each step result separately!
• Do not skip steps!

Step 1: Collect Scores per Criterion

Create a table with each criterion and scores from all evaluations:

Criterion	Eval 1	Eval 2	Median	Difference
[Name 1]	X.X	X.X	?	?
[Name 2]	X.X	X.X	?	?

Step 2: Calculate Median for Each Criterion

For 2 evaluations: Median = (Score1 + Score2) / 2

For 3+ evaluations: Sort scores, take middle value (or average of two middle values if even count)

Step 3: Check for High Variance

High variance = evaluators disagree significantly (difference > 2.0 points)

Formula: |Eval1 - Eval2| > 2.0 → Flag as high variance

Step 4: Calculate Weighted Overall Score

Multiply each criterion's median by its weight and sum:

Overall = (Criterion1_Median × Weight1) + (Criterion2_Median × Weight2) + ...

Step 5: Determine Pass/Fail

Compare overall score to threshold:

• Overall ≥ Threshold → PASS ✅
• Overall < Threshold → FAIL ❌

---

Handling Disagreement

If evaluations significantly disagree (difference > 2.0 on any criterion):

1. Flag the criterion
2. Present both evaluators' reasoning
3. Ask user: "Evaluators disagree on [criterion]. Review manually?"
4. If yes: present evidence, get user decision
5. If no: use median (conservative approach)

Final Report

After all steps complete and DoD verification passes:

Usage Examples

Basic Usage

# Implement a specific task
/implement add-validation.feature.md

# Auto-select task from todo/ or in-progress/ (if only 1 task)
/implement

# Continue from last completed step
/implement add-validation.feature.md --continue

# Refine after user fixes project files (detects changes, re-verifies affected steps)
/implement add-validation.feature.md --refine

# Human review after every step
/implement add-validation.feature.md --human-in-the-loop

# Human review after specific steps only
/implement add-validation.feature.md --human-in-the-loop 2,4,6

# Higher quality threshold (stricter) - sets both standard and critical to 4.5
/implement add-validation.feature.md --target-quality 4.5

# Different thresholds for standard (3.5) and critical (4.5) components
/implement add-validation.feature.md --target-quality 3.5,4.5

# Lower quality threshold for both (faster convergence)
/implement add-validation.feature.md --target-quality 3.5

# Unlimited iterations (default is 3)
/implement add-validation.feature.md --max-iterations unlimited

# Skip all judge verifications (fast but no quality gates)
/implement add-validation.feature.md --skip-judges

# Combined: continue with human review
/implement add-validation.feature.md --continue --human-in-the-loop

Error Handling

Implementation Failure

If sdd:developer agent reports failure:

1. Present the failure details to user
2. Ask clarification questions that could help resolve
3. Launch sdd:developer agent again with clarifications

Judge Disagreement

If judges disagree significantly (difference > 2.0):

1. Present both perspectives with evidence
2. Ask user to resolve: "Judges disagree. Your decision?"
3. Proceed based on user decision

Refine Mode: No Changes Detected

If --refine mode finds no git changes in the project:

1. Report: "No project file changes detected since last commit."
2. Suggest: "Make edits to project files first, then run --refine again."
3. Alternatively: "Run without --refine to re-implement all steps."

Refine Mode: Changes Don't Map to Steps

If --refine mode finds changed files but none map to implementation steps:

1. Report: "Changed files don't match any implementation step's expected outputs."
2. List the changed files detected
3. Suggest: "Verify manually or run without --refine to re-verify all steps."

Checklist

Before completing implementation:

Configuration Handling

• Parsed all flags from $ARGUMENTS correctly
• Used THRESHOLD_FOR_STANDARD_COMPONENTS for standard steps
• Used THRESHOLD_FOR_CRITICAL_COMPONENTS for critical steps
• Iterated until quality threshold met (or MAX_ITERATIONS reached, default 3)
• Triggered human-in-the-loop checkpoints ONLY for steps in HUMAN_IN_THE_LOOP_STEPS
• If SKIP_JUDGES is true: Skipped ALL judge validation
• If CONTINUE_MODE is true: Verified last step and resumed correctly
• If REFINE_MODE is true: Detected changed project files, mapped to steps, re-verified from earliest affected step

Context Protection (CRITICAL)

• Read ONLY the task file ($TASK_PATH in .memory-bank/specs/tasks/in-progress/) - no other files
• Did NOT read implementation outputs, reference files, or artifacts
• Used sub-agent reports for status - did NOT read files to "check"

Delegation

• ALL implementations done by sdd:developer agents via Task tool
• ALL evaluations done by sdd:developer agents via Task tool
• Did NOT perform any verification yourself
• Did NOT skip any verification steps (unless SKIP_JUDGES is true)

Stage Tracking

• Each step marked complete ONLY after judge PASS (or immediately if SKIP_JUDGES)
• Task file updated after each step completion:
  • Step title marked with [DONE]
  • Subtasks marked with [X]
• Todo list updated after each step completion

Execution Quality

• All steps executed in dependency order
• Parallel steps launched simultaneously (not sequentially)
• Each sdd:developer agent received focused prompt with exact step
• All critical artifacts evaluated by judges (unless SKIP_JUDGES)
• Panel voting used for high-stakes artifacts
• Chain-of-thought requirement included in all evaluation prompts
• Failed evaluations iterated until quality threshold met
• Final report generated with judge confirmation status
• User informed of any evaluator disagreements

Human-in-the-Loop (if enabled)

• Displayed checkpoint after each step in HUMAN_IN_THE_LOOP_STEPS
• Incorporated user feedback into subsequent iterations/steps
• Paused workflow when user requested

Final Verification and Completion

• Definition of Done verification agent launched
• All DoD items verified (PASS/FAIL/BLOCKED status)
• Failing DoD items fixed via sdd:developer agents
• Re-verification performed after fixes
• Task moved from in-progress/ to done/ folder
• All DoD checkboxes marked [X] in task file
• Final verification report presented to user

Appendix A: Verification Specifications Reference

This appendix documents how verification is specified in task files. During Phase 2 (Execute Steps), you will reference these specifications to understand how to verify each artifact.

How Task Files Define Verification

Task files define verification requirements in #### Verification sections within each implementation step. These sections specify:

Required Elements

1. Level: Verification complexity

   • None - Simple operations (mkdir, delete) - skip verification
   • Single Judge - Non-critical artifacts - 1 judge, threshold 4.0/5.0
   • Panel of 2 Judges - Critical artifacts - 2 judges, median voting, threshold 4.0/5.0 or 4.5/5.0
   • Per-Item Judges - Multiple similar items - 1 judge per item, parallel execution

2. Artifact(s): Path(s) to file(s) being verified

   • Example: src/decision/decision.service.ts, src/decision/tests/decision.service.spec.ts

3. Threshold: Minimum passing score

   • Typically 4.0/5.0 for standard quality
   • Sometimes 4.5/5.0 for critical components

4. Rubric: Weighted criteria table (see format below)

5. Reference Pattern (Optional): Path to example of good implementation

   • Example: src/app.service.ts for NestJS service patterns

Rubric Format

Rubrics in task files use this markdown table format:

| Criterion | Weight | Description |
|-----------|--------|-------------|
| [Name 1]  | 0.XX   | [What to evaluate] |
| [Name 2]  | 0.XX   | [What to evaluate] |
| ...       | ...    | ...         |

Requirements:

• Weights MUST sum to 1.0
• Each criterion has a clear, measurable description
• Typically 3-6 criteria per rubric

Example:

| Criterion | Weight | Description |
|-----------|--------|-------------|
| Type Correctness | 0.35 | Types match specification exactly |
| API Contract Alignment | 0.25 | Aligns with documented API contract |
| Export Structure | 0.20 | Barrel exports correctly expose all types |
| Code Quality | 0.20 | Follows project TypeScript conventions |

Scoring Scale

When judges evaluate artifacts, they use this 5-point scale for each criterion:

• 1 (Poor): Does not meet requirements

  • Missing essential elements
  • Fundamental misunderstanding of requirements

• 2 (Below Average): Multiple issues, partially meets requirements

  • Some correct elements, but significant gaps
  • Would require substantial rework

• 3 (Adequate): Meets basic requirements

  • Functional but minimal
  • Room for improvement in quality or completeness

• 4 (Good): Meets all requirements, few minor issues

  • Solid implementation
  • Minor polish could improve it

• 5 (Excellent): Exceeds requirements

  • Exceptional quality
  • Goes beyond what was asked
  • Could serve as reference implementation

Using Verification Specs During Execution

During Phase 2 (Execute Steps):

1. After a sdd:developer agent completes implementation
2. Read the step's #### Verification section in the task file
3. Extract: Level, Artifact paths, Threshold, Rubric, Reference Pattern
4. Launch appropriate judge agent(s) based on Level
5. Provide judges with: Artifact path, Rubric, Threshold, Reference Pattern
6. Aggregate judge results and determine PASS/FAIL
7. If FAIL, launch sdd:developer agent to fix issues and re-verify

Example Verification Section in Task File:

#### Verification

**Level:** Panel of 2 Judges with Aggregated Voting
**Artifact:** `src/decision/decision.service.ts`, `src/decision/tests/decision.service.spec.ts`

**Rubric:**

| Criterion | Weight | Description |
|-----------|--------|-------------|
| Routing Logic | 0.20 | Correctly routes by customerType |
| Drip Feed Implementation | 0.25 | 2% random approval for rejected New customers only |
| Response Formatting | 0.20 | Correct decision outcome, triggeredRules preserved, ISO 8601 timestamp |
| Testability | 0.15 | Injectable randomGenerator enables deterministic testing |
| Test Coverage | 0.20 | Unit tests cover approval, rejection, drip feed, routing, timestamp |

**Reference Pattern:** NestJS service patterns, ZenEngineService API

This specification tells you to:

• Launch 2 judge agents in parallel
• Have them evaluate both service and test files
• Use the 5-criterion rubric with specified weights
• Do not pass threshold to judges, only use it to compare it with the average score of the judges
• Reference existing NestJS patterns for comparison
