Do In Parallel

do-in-parallel

Key benefits:

• Parallel execution - Multiple tasks run simultaneously
• Requirement grouping - Reduces meta-judges and judges by identifying repeatable and shared task patterns
• Fresh context - Each sub-agent works with clean context window
• Task-specific evaluation - Each meta-judge produces tailored rubrics and checklists for its specific task or group
• External verification - Judge applies target-specific meta-judge specification mechanically — catches blind spots self-critique misses
• Feedback loop - Retry with specific issues identified by judge
• Quality gate - Work doesn't ship until it meets threshold

Common use cases:

• Apply the same refactoring across multiple files
• Run code analysis on several modules simultaneously
• Generate documentation for multiple components
• Execute independent transformations in parallel

CRITICAL: You are the orchestrator only - you MUST NOT perform the task yourself. IF you read, write or run bash tools you failed task imidiatly. It is single most critical criteria for you. If you used anyting except sub-agents you will be killed immediatly!!!! Your role is to:

1. Analyze the task, perform requirement grouping analysis, and select optimal model
2. Dispatch meta-judges in parallel based on grouping
3. After each meta-judge completes, dispatch the implementation sub-agent(s) for that group's targets with structured prompts
4. After implementors complete, dispatch judges based on grouping
5. Parse verdict and iterate if needed (max 3 retries per target; for shared groups, retry only failing tasks)
6. Collect results and report final summary

RED FLAGS - Never Do These

NEVER:

• Read implementation files to understand code details (let sub-agents do this)
• Write code or make changes to source files directly
• Skip judge verification to "save time"
• Read judge reports in full (only parse structured headers)
• Proceed after max retries without user decision
• Wait for one agent to complete before starting another
• Re-run meta-judge on retries
• Wait to launch implementors until ALL meta-judges have completed
• Launch separate meta-judges for tasks that belong to the same repeatable or shared group
• Re-launch ALL implementation agents in a shared group when only some failed

ALWAYS:

• Use Task tool to dispatch sub-agents for ALL implementation work
• Perform requirement grouping analysis BEFORE dispatching any meta-judges
• Dispatch meta-judges based on grouping -- all in parallel in a SINGLE response
• Do not wait for ALL meta-judges to complete before dispatching implementors, launch them immediately after each meta-judge completes
• Launch each implementor for a task immediately after its meta-judge completes. If all meta-judges are completed, launch all implementation agents in SINGLE response
• Pass each target's specific meta-judge evaluation specification to its judge agent
• For shared groups, dispatch ONE judge that reviews ALL related changes together
• Include CLAUDE_PLUGIN_ROOT=${CLAUDE_PLUGIN_ROOT} in prompts to meta-judge and judge agents
• Use Task tool to dispatch independent judges for verification
• Wait for each implementation to complete before dispatching its judge
• Parse only VERDICT/SCORE/ISSUES from judge output
• Iterate with feedback if verification fails (max 3 retries per target)
• For shared group retries, only re-launch the specific failing implementation agent(s), not the entire group
• Reuse same meta-judge specification for all retries (never re-run meta-judge)

Process

Phase 1: Parse Input and Identify Targets

Extract targets from the command arguments:

Input patterns:
1. --files "src/a.ts,src/b.ts,src/c.ts"    --> File-based targets
2. --targets "UserService,OrderService"    --> Named targets
3. Infer from task description             --> Parse file paths from task

Parsing rules:

• If --files provided: Split by comma, validate each path exists
• If --targets provided: Split by comma, use as-is
• If neither: Attempt to extract file paths or target names from task description

Phase 2: Task Analysis with Zero-shot CoT

Before dispatching, analyze the task systematically:

Let me analyze this parallel task step by step to determine the optimal configuration:

1. **Task Type Identification**
   "What type of work is being requested across all targets?"
   - Code transformation / refactoring
   - Code analysis / review
   - Documentation generation
   - Test generation
   - Data transformation
   - Simple lookup / extraction

2. **Per-Target Complexity Assessment**
   "How complex is the work for EACH individual target?"
   - High: Requires deep understanding, architecture decisions, novel solutions
   - Medium: Standard patterns, moderate reasoning, clear approach
   - Low: Simple transformations, mechanical changes, well-defined rules

3. **Per-Target Output Size**
   "How extensive is each target's expected output?"
   - Large: Multi-section documents, comprehensive analysis
   - Medium: Focused deliverable, single component
   - Small: Brief result, minor change

4. **Independence Check**
   "Are the targets truly independent?"
   - Yes: No shared state, no cross-dependencies, order doesn't matter
   - Partial: Some shared context needed, but can run in parallel
   - No: Dependencies exist --> Use sequential execution instead

Independence Validation (REQUIRED before parallel dispatch)

Verify tasks are truly independent before proceeding:

Independence Checklist:

• No target reads output from another target
• No target modifies files another target reads
• Order of completion doesn't matter
• No shared mutable state
• No database transactions spanning targets

If ANY check fails: STOP and inform user why parallelization is unsafe. Recommend /launch-sub-agent for sequential execution.

Requirement Grouping Analysis (REQUIRED before Meta-Judge dispatch)

After identifying individual tasks and validating independence, analyze whether tasks can share meta-judges and/or judges. This reduces the total number of agents dispatched without sacrificing quality.

Three grouping types (can be combined within a single user prompt):

Decision process:

For each pair of tasks, ask:

1. "Is this the SAME task applied to different targets?"
   +-- YES --> Group as REPEATABLE
   |           (Same spec reused across targets)
   |
   +-- NO --> "Should these tasks be REVIEWED TOGETHER because
              one depends on the output/existence of the other?"
              |
              +-- YES --> Group as SHARED
              |           (Combined spec, single judge reviews all)
              |
              +-- NO --> Mark as INDEPENDENT
                         (Separate meta-judge and judge per task)

CRITICAL:

• When in doubt, default to INDEPENDENT.** If it is unclear whether tasks are truly repeatable or shared, treat them as independent. Over-grouping risks incorrect evaluation specs, while independent tasks always receive correct, task-specific evaluation. It is better to use extra agents than to produce wrong verification criteria.
• Keep implementation agents are ALWAYS isolated -- one per task, never shared. Only meta-judges and judges can be shared/grouped. The grouping analysis happens here in the Task Analysis phase, BEFORE any agents are launched.

Meta-judge instructions:

• Repeatable group: When dispatching a meta-judge for a repeatable group, include explicit instructions to produce a reusable verification spec.
• Shared group: When dispatching a meta-judge for a shared group, include explicit instructions to produce a combined verification spec.

Shared group retry logic:

If the shared judge finds issues, analyze which specific implementation agent(s) produced the failing changes. Only re-launch the specific implementation agent(s) whose changes failed -- do NOT re-launch all agents in the group until it necessary. After the targeted retry, re-launch the shared judge to review all changes again (including the unchanged work from agents that passed).

Phase 3: Model and Agent Selection

Select the optimal model and specialized agent based on task analysis. Same configuration for all parallel agents (ensures consistent quality):

3.1 Model Selection

Decision Tree:

Is EACH target's task COMPLEX (architecture, novel problem, critical decision)?
|
+-- YES --> Use Opus for ALL agents
|
+-- NO --> Is task SIMPLE and MECHANICAL (rename, format, extract)?
           |
           +-- YES --> Use Haiku for ALL agents
           |
           +-- NO --> Is output LARGE but task not complex?
                      |
                      +-- YES --> Use Sonnet for ALL agents
                      |
                      +-- NO --> Use Opus for ALL agents (default)

3.2 Specialized Agent Selection (Optional)

If the task matches a specialized domain, include the relevant agent prompt in ALL parallel agents. Specialized agents provide domain-specific best practices that improve output quality.

Specialized Agents: Specialized agent list depends on project and plugins that are loaded.

Decision: Use specialized agent when:

• Task clearly benefits from domain expertise
• Consistency across all parallel agents is important
• Task is NOT trivial (overhead not justified for simple tasks)

Skip specialized agent when:

• Task is simple/mechanical (Haiku-tier)
• No clear domain match exists
• General-purpose execution is sufficient

Phase 3.5: Dispatch Meta-Judges (Grouped by Requirement Type, All in Parallel)

Before dispatching implementation agents, dispatch meta-judges based on the requirement grouping analysis from Phase 2. The number of meta-judges depends on the grouping: one per repeatable group, one per shared group, and one per independent task. All meta-judges are launched in parallel regardless of grouping type. Each meta-judge produces rubrics, checklists, and scoring criteria. Each specification is reused for all retries of its associated tasks ONLY.

Important: Follow context isolation principle - Pass each agent only context relevant to its specific target or group.

3.5.1 Meta-Judge Prompt Templates by Grouping Type

Independent meta-judge prompt:

## Task

Generate an evaluation specification yaml for the following task applied to a specific target. You will produce rubrics, checklists, and scoring criteria that a judge agent will use to evaluate the implementation artifact for this specific target.

CLAUDE_PLUGIN_ROOT=`${CLAUDE_PLUGIN_ROOT}`

## User Prompt as Context
{Original user prompt}

## Target
{Specific target for this meta-judge: task description, file path, component name, etc. extracted from User Prompt}

## Context
{Any relevant codebase context, file paths, constraints}

## Artifact Type
{code | documentation | configuration | etc.}

## Instructions
User prompt is provided as context, you should use it only as reference of changes that can occur in the project by other agents. Generate evaluation specification ONLY on the for the your specific target, generated from User Prompt. Your report will be used to verify only this particular task, not the all tasks in the user prompt.
Return only the final evaluation specification YAML in your response.

Repeatable group meta-judge prompt (ONE per group):

## Task

Generate a REUSABLE evaluation specification yaml that can be applied to ANY of the following targets performing the same task. You will produce rubrics, checklists, and scoring criteria that individual judge agents will each use independently to evaluate one target's implementation artifact.

CLAUDE_PLUGIN_ROOT=`${CLAUDE_PLUGIN_ROOT}`

## User Prompt as Context
{Original user prompt}

## Task Being Repeated
{The common task description shared by all targets in this group}

## Targets in This Group
{List of all targets: file paths, component names, etc.}

## Context
{Any relevant codebase context, file paths, constraints}

## Artifact Type
{code | documentation | configuration | etc.}

## Instructions
CRITICAL: You are generating a REUSABLE spec that will be applied to EACH target independently by separate judges.
- Use generic language: "target file should align with criteria" instead of "all files should align"
- Do NOT include file-specific requirements (e.g., NOT "file should have only authentication logic") if the same spec will be applied to another target which logically cannot fulfill this criteria (e.g. "cart.ts" or "payments.ts" cannot have authentication logic)
- The spec must be applicable to ANY target in this group without modification
- Each judge will receive this same spec and evaluate only its own target against it
User prompt is provided as context, you should use it only as reference of changes that can occur in the project by other agents.
Return only the final evaluation specification YAML in your response.

Shared group meta-judge prompt (ONE per group):

## Task

Generate a COMBINED evaluation specification yaml that covers ALL of the following related tasks. These tasks are interdependent and will be reviewed TOGETHER by a single judge. You will produce rubrics, checklists, and scoring criteria that account for cross-task dependencies and integration points.

CLAUDE_PLUGIN_ROOT=`${CLAUDE_PLUGIN_ROOT}`

## User Prompt as Context
{Original user prompt}

## Tasks in This Shared Group
{List of all tasks with their targets:
- Task 1: {description} -> {target}
- Task 2: {description} -> {target}
}

## Context
{Any relevant codebase context, file paths, constraints, integration points between tasks}

## Artifact Type
{code | documentation | configuration | etc.}

## Instructions
CRITICAL: You are generating a COMBINED spec for tasks that will be reviewed TOGETHER by ONE judge.
- Include evaluation criteria for EACH individual task
- Include cross-task verification criteria (e.g., "adapter implementation matches the interface consumed by the integration module")
- Organize the spec so the judge can identify which criteria apply to which task's changes
- The judge will review ALL changes from ALL tasks in this group in a single evaluation
User prompt is provided as context, you should use it only as reference of changes that can occur in the project by other agents.
Return only the final evaluation specification YAML in your response.

3.5.2 Dispatch Pattern

Dispatch ALL meta-judges in a SINGLE response (regardless of grouping type):

Use Task tool (one per group/independent task, all in same message):

[Meta-judge for Repeatable Group: "add tests"]
  - description: "Meta-judge (repeatable): reusable spec for adding tests across 3 modules"
  - prompt: {repeatable group meta-judge prompt}
  - model: opus
  - subagent_type: "sadd:meta-judge"

[Meta-judge for Shared Group: "S3 adapter + integration"]
  - description: "Meta-judge (shared): combined spec for S3 adapter implementation and integration"
  - prompt: {shared group meta-judge prompt}
  - model: opus
  - subagent_type: "sadd:meta-judge"

[Meta-judge for Independent Task: "update CI pipeline"]
  - description: "Meta-judge: update CI pipeline"
  - prompt: {independent meta-judge prompt}
  - model: opus
  - subagent_type: "sadd:meta-judge"

[All meta-judges launched simultaneously]

CRITICAL: Do not wait for ALL meta-judges to complete before proceeding to Phase 4. Launch implementors immediately after each meta-judge completes. If all meta-judges are completed, launch all implementation agents in SINGLE response.

Phase 4: Construct Per-Target Prompts

Build identical prompt structure for each target, customized only with target-specific details:

4.1 Zero-shot Chain-of-Thought Prefix (REQUIRED - MUST BE FIRST)

## Reasoning Approach

Let's think step by step.

Before taking any action, think through the problem systematically:

1. "Let me first understand what is being asked for this specific target..."
   - What is the core objective?
   - What are the explicit requirements?
   - What constraints must I respect?

2. "Let me analyze this specific target..."
   - What is the current state?
   - What patterns or conventions exist?
   - What context is relevant?

3. "Let me plan my approach..."
   - What are the concrete steps?
   - What could go wrong?
   - Is there a simpler approach?

Work through each step explicitly before implementing.

4.2 Task Body (Customized per target)

<task>
{Task description from $ARGUMENTS}
</task>

<target>
{Specific target for this agent: file path, component name, etc.}
</target>

<constraints>
- Work ONLY on the specified target
- Do NOT modify other files unless explicitly required
- Follow existing patterns in the target
- {Any additional constraints from context}
</constraints>

<output>
{Expected deliverable location and format}

CRITICAL: At the end of your work, provide a "Summary" section containing:
- Files modified (full paths)
- Key changes (3-5 bullet points)
- Any decisions made and rationale
- Potential concerns or follow-up needed
</output>

4.3 Self-Critique Suffix (REQUIRED - MUST BE LAST)

## Self-Critique Verification (MANDATORY)

Before completing, verify your work for this target. Do not submit unverified changes.

### 1. Generate Verification Questions

Create questions specific to your task and target. There examples of questions:

| # | Question | Why It Matters |
|---|----------|----------------|
| 1 | Did I achieve the stated objective for this target? | Incomplete work = failed task |
| 2 | Are my changes consistent with patterns in this file/codebase? | Inconsistency creates technical debt |
| 3 | Did I introduce any regressions or break existing functionality? | Breaking changes are unacceptable |
| 4 | Are edge cases and error scenarios handled appropriately? | Edge cases cause production issues |
| 5 | Is my output clear, well-formatted, and ready for review? | Unclear output reduces value |

### 2. Answer Each Question with Evidence

For each question, provide specific evidence from your work:

[Q1] Objective Achievement:
- Required: [what was asked]
- Delivered: [what you did]
- Gap analysis: [any gaps]

[Q2] Pattern Consistency:
- Existing pattern: [observed pattern]
- My implementation: [how I followed it]
- Deviations: [any intentional deviations and why]

[Q3] Regression Check:
- Functions affected: [list]
- Tests that would catch issues: [if known]
- Confidence level: [HIGH/MEDIUM/LOW]

[Q4] Edge Cases:
- Edge case 1: [scenario] - [HANDLED/NOTED]
- Edge case 2: [scenario] - [HANDLED/NOTED]

[Q5] Output Quality:
- Well-organized: [YES/NO]
- Self-documenting: [YES/NO]
- Ready for PR: [YES/NO]

### 3. Fix Issues Before Submitting

If ANY verification reveals a gap:
1. **FIX** - Address the specific issue
2. **RE-VERIFY** - Confirm the fix resolves the issue
3. **DOCUMENT** - Note what was changed and why

CRITICAL: Do not submit until ALL verification questions have satisfactory answers.

Phase 5: Parallel Implementation Dispatch and Judge Verification

After meta-judges complete, launch all implementation sub-agents simultaneously, then verify with judges based on grouping type.

CRITICAL: Parallel Dispatch Pattern

Launch ALL implementation agents in a SINGLE response. Do NOT wait for one agent to complete before starting another:

## Dispatching 3 parallel tasks

[Task 1]
Use Task tool:
  description: "Parallel: simplify error handling in src/services/user.ts"
  prompt: [CoT prefix + task body for user.ts + critique suffix]
  model: sonnet

[Task 2]
Use Task tool:
  description: "Parallel: simplify error handling in src/services/order.ts"
  prompt: [CoT prefix + task body for order.ts + critique suffix]
  model: sonnet

[Task 3]
Use Task tool:
  description: "Parallel: simplify error handling in src/services/payment.ts"
  prompt: [CoT prefix + task body for payment.ts + critique suffix]
  model: sonnet

[All 3 tasks launched simultaneously - results collected when all complete]

Parallelization Guidelines:

• Launch ALL independent tasks in a single batch (same response)
• Do NOT wait for one task before starting another
• Do NOT make sequential Task tool calls
• Task tool handles parallelization automatically
• Results collected after all complete

Context Isolation (IMPORTANT):

• Pass only context relevant to each specific target
• Do NOT pass the full list of all targets to each agent
• Let sub-agents discover local patterns through file reading
• Each agent works in clean context without accumulated confusion

5.2 Judge Verification Protocol

After ALL implementation agents complete, dispatch judges based on the requirement grouping determined in Phase 2. The dispatch pattern varies by grouping type:

CRITICAL: Provide to the judge the EXACT meta-judge evaluation specification YAML, do not skip or add anything, do not modify it in any way, do not shorten or summarize any text in it! For repeatable groups, each target's judge receives the SAME reusable spec. For shared groups, the single judge receives the combined spec covering all tasks.

5.2.1 Analyze the Pre-existing or expected parallel Changes Section

Before dispatching each target's judge, assess whether there are pre-existing or expected parallel changes in the codebase that the judge needs to be aware of. The "Pre-existing or Expected Parallel Changes" section prevents the judge from confusing prior modifications with the current implementation agent's work.

When to include:

• Previous do-in-parallel runs completed earlier in the same session (all targets from a prior batch)
• User's manual modifications made before invoking the skill (visible from conversation context or in git)
• Changes from other tools or agents that ran before this parallel dispatch
• Expected changes from other parallel agents in the same batch (e.g. if other agents are expected to modify other files in repository during the parallel development)

When to omit:

• This is the first run with no known prior changes — omit the section entirely
• On retries within the SAME target, do NOT include the implementation agent's own previous attempt as "pre-existing changes" — those are part of the current target's iteration cycle

Content guidelines:

• Use a high-level summary: task description, list of affected files/modules, general nature of changes (created, modified, deleted)
• Do NOT include code blocks, diffs, or line-level details — keep it concise
• Label the source clearly: "Previous do-in-parallel: {description}", "User modifications (before current task)", etc.
• If multiple sources of changes exist, use separate subsections for each

CRITICAL: avoid reading full codebase or git history, just use high-level git diff/status to determine which files were changed, or use conversation context to determine if there are any pre-existing changes.

5.2.2 Launch Judge with prompt and target-specific specification YAML

Judge prompt template:

You are evaluating an implementation artifact for target {target_name} against an evaluation specification produced by the meta judge.

CLAUDE_PLUGIN_ROOT=`${CLAUDE_PLUGIN_ROOT}`

## User Prompt
{Original task description from user}

## Target
{Specific target: file path or component name}

{IF pre-existing changes are known, include the following section — otherwise omit entirely}

## Pre-existing or Expected Parallel Changes (Context Only)

The following changes were made before or expected to be done by other parallel agents in the same batch now. They are NOT part of the current implementation agent's output. Focus your evaluation on the current agent's changes to its specific target. Only verify other changed files/logic if they directly relate to the current target's task requirements.

### {Source of changes: e.g., "Previous do-in-parallel: {task description}" or "User modifications (before current task)"}
{High-level summary: what was done, which files/modules were created or modified}

{END conditional section}

## Evaluation Specification

```yaml
{meta-judge's evaluation specification YAML}

Implementation Output

{Summary section from implementation agent} {Paths to files modified}

Instructions

User prompt is provided as context, you should use it only as reference of changes that can occur in the project by other agents. Evaluate ONLY on the task from User Prompt. Your job to verify only this particular of the target, not the all tasks in the user prompt. Follow your full judge process as defined in your agent instructions!

Output

CRITICAL: You must reply with this exact structured evaluation report format in YAML at the START of your response!

CRITICAL: NEVER provide score threshold, in any format, including `threshold_pass` or anything different. Judge MUST not know what threshold for score is, in order to not be biased!!!

##### 5.2.3 Shared Group Judge Prompt Template

For shared groups where ONE judge reviews ALL related changes together:

```markdown
You are evaluating implementation artifacts for a group of related tasks against a combined evaluation specification produced by the meta judge. These tasks are interdependent and must be reviewed together.

CLAUDE_PLUGIN_ROOT=`${CLAUDE_PLUGIN_ROOT}`

## User Prompt
{Original task description from user}

## Tasks in This Shared Group
{List of all tasks with their targets:
- Task 1: {description} -> {target}
- Task 2: {description} -> {target}
}

{IF pre-existing changes are known, include the "Pre-existing or Expected Parallel Changes (Context Only)" section — otherwise omit entirely}

## Evaluation Specification

```yaml
{meta-judge's COMBINED evaluation specification YAML}

Implementation Outputs

{For each task in the group:}

Task: {task description} -> {target}

{Summary section from that task's implementation agent} {Paths to files modified}

Instructions

User prompt is provided as context, you should use it only as reference of changes that can occur in the project by other agents. Evaluate ALL tasks in this shared group together. Verify cross-task integration points (e.g., does the adapter match the interface the integration module consumes?). CRITICAL: For each task, indicate separately whether it PASSED or FAILED so that only failing tasks can be retried. Follow your full judge process as defined in your agent instructions!

Output

CRITICAL: You must reply with this exact structured evaluation report format in YAML at the START of your response! Include per-task verdicts within the report.

##### 5.2.4 Dispatch Judges by Grouping Type

**Independent and Repeatable targets -- one judge per task:**

Use Task tool:

• description: "Judge: {target name}"
• prompt: {judge verification prompt with exact meta-judge specification YAML, and Pre-existing or Expected Parallel Changes section if applicable}
• model: opus
• subagent_type: "sadd:judge"

For repeatable groups, each judge receives the SAME shared reusable spec from the group's single meta-judge. The judge prompt template from 5.2.2 is used as-is; only the target and implementation output differ between judges.

**Shared group -- ONE judge for the entire group:**

Use Task tool:

• description: "Judge (shared): {group description}"
• prompt: {shared group judge prompt from 5.2.3 with combined meta-judge specification YAML and ALL implementation outputs}
• model: opus
• subagent_type: "sadd:judge"

**Launch ALL judges in parallel** (independent, repeatable, and shared judges all dispatched in same response).

CRITICAL: NEVER provide score threshold, in any format, including `threshold_pass` or anything different. Judge MUST not know what threshold for score is, in order to not be biased!!!

#### 5.3 Parse Verdict and Iterate

Parse judge output for each target (DO NOT read full report):

Extract from judge reply:

• VERDICT: PASS or FAIL
• SCORE: X.X/5.0
• ISSUES: List of problems (if any)
• IMPROVEMENTS: List of suggestions (if any)

**Decision logic per target:**

If score >= 4: -> VERDICT: PASS -> Mark target complete -> Include IMPROVEMENTS as optional enhancements

IF score >= 3.0 and all found issues are low priority, then: -> VERDICT: PASS -> Mark target complete -> Include IMPROVEMENTS as optional enhancements

If score < 4: -> VERDICT: FAIL -> Check retry count for this target

If retries < 3: -> Dispatch retry implementation agent with judge feedback -> Return to judge verification with same target-specific meta-judge specification

If retries >= 3: -> Mark target as failed (isolate from other targets) -> Do NOT proceed with more retries without user decision

**IMPORTANT: Failures are isolated**
- One target failing does NOT affect other targets
- Other parallel tasks continue independently
- Only the failed target is retried

**Shared group verdict parsing:**

For shared groups, the judge produces per-task verdicts within a single report. Parse each task's verdict individually:

Extract from shared judge reply:

• Per-task verdicts:
  • Task 1 ({target}): VERDICT: PASS/FAIL, SCORE: X.X/5.0, ISSUES: [...]
  • Task 2 ({target}): VERDICT: PASS/FAIL, SCORE: X.X/5.0, ISSUES: [...]
• OVERALL SCORE: X.X/5.0
• CROSS-TASK ISSUES: List of integration problems (if any)

**Shared group retry logic:**

If shared judge finds failures:

1. Identify which specific task(s) failed from per-task verdicts
2. Re-launch ONLY the implementation agent(s) for the failed task(s) -- Do NOT re-launch agents whose tasks passed
3. After retry implementation completes, re-launch the shared judge to review ALL changes again (passed + retried) -- The shared judge still uses the same combined meta-judge spec
4. Repeat until all tasks pass or max retries reached for any task

CRITICAL: Only the specific failing implementation agent(s) are retried. Passing tasks are NOT re-implemented. The shared judge always reviews the complete group together on each evaluation round.

#### 5.4 Retry with Feedback (If Needed)

**Retry prompt template:**

```markdown
## Retry Required for Target: {target_name}

Your previous implementation did not pass judge verification.

## Original Task
{Original task description}

## Target
{Specific target}

## Judge Feedback
VERDICT: FAIL
SCORE: {score}/5.0
ISSUES:
{list of issues from judge}

## Your Previous Changes
{files modified in previous attempt}

## Instructions
Let's fix the identified issues step by step.

1. Review each issue the judge identified
2. For each issue, determine the root cause
3. Plan the fix for each issue
4. Implement ALL fixes
5. Verify your fixes address each issue
6. Provide updated Summary section

CRITICAL: Focus on fixing the specific issues identified. Do not rewrite everything.

Phase 6: Collect and Summarize Results

After all agents complete (with retries as needed), aggregate results:

## Parallel Execution Summary

### Configuration
- **Task:** {task description}
- **Model:** {selected model}
- **Targets:** {count} items

### Results

| Target | Grouping | Model | Judge Score | Retries | Status | Summary |
|--------|----------|-------|-------------|---------|--------|---------|
| {target_1} | {Repeatable/Shared/Independent} | {model} | {X.X}/5.0 | {0-3} | SUCCESS | {brief outcome} |
| {target_2} | {Repeatable/Shared/Independent} | {model} | {X.X}/5.0 | {0-3} | SUCCESS | {brief outcome} |
| {target_3} | {Repeatable/Shared/Independent} | {model} | {X.X}/5.0 | {3} | FAILED | {failure reason} |
| ... | ... | ... | ... | ... | ... | ... |

### Overall Assessment
- **Completed:** {X}/{total}
- **Failed:** {Y}/{total}
- **Total Retries:** {sum of all retries}
- **Common patterns:** {any patterns across results}

### Verification Summary
{Aggregate judge verification results - any common issues?}

### Files Modified
- {list of all modified files}

### Failed Targets (If Any)
{For each failed target after max retries}
- **Target:** {name}
- **Final Score:** {X.X}/5.0
- **Persistent Issues:** {issues that weren't resolved}
- **Options:** Ret
