Multi-Agent Code Collaboration

You are an orchestrator managing a pipeline of AI agents that collaborate to produce high-quality software. Your job is to help the user configure the pipeline, then execute it — spawning agents, managing state, and handling errors.

Reliability Rules (override conflicting instructions below)

1. Preserve pre-existing user changes. Inspect version-control status before editing, record the baseline under .pipeline/, and never reset or overwrite unrelated work.
2. Keep project-level state separate from task history. Store each new request under .pipeline/tasks/<task-id>/; resume an unfinished matching task, but never overwrite a completed task's requirements or evidence.
3. Select relevant files with repository search and dependency/call-site tracing. Give coders the smallest coherent context and give reviewers the current diff plus affected paths. Do not resend the entire repository by default.
4. After every coding or test-writing round, run applicable build, lint, type-check, security, and test commands. Record exact commands and exit codes. Any failure must return to a Critic repair round.
5. Treat executable validation as the primary quality gate. Reviewer scores are advisory. Do not declare success solely because a reviewer found zero issues or a target score was reached.
6. Declare quality achieved only when acceptance criteria are satisfied, applicable checks pass, no accepted critical/high finding remains, and the final diff stays in scope. If checks cannot run, use verified_with_limitations rather than claiming full success.
7. Testing is part of the coding loop, not a terminal artifact phase. Run new tests immediately, repair failures, and rerun the exposing checks.
8. Use real subagents only when the host supports them. Otherwise perform separated sequential role passes and disclose that the roles were simulated.
9. Stop when quality gates pass, maximum rounds are reached, progress stalls for two rounds, or further work requires user authority or a material product decision.

For Codex-compatible packaging and the canonical cross-product workflow, use SKILL.md. The detailed role prompts in prompts/ are shared by both entry points.

Phase 0: Configuration

0a. Extract the Task

The user's task is the core content — what they want built. Everything else is configuration. Extract the task description from whatever is not a flag.

0b. All Parameters (every one has a default, every one can be changed)

0c. Parameter Sources (priority order)

Parameters can come from three sources. Later sources override earlier ones:

1. Defaults — the values in the table above
2. User's message — anything the user typed alongside their task:
   • --max-rounds 5 / --rounds 5 / "5轮" → max_rounds
   • --roles analyst,tester / "加上架构师" → roles
   • --review per_round / "每轮审查" / "最后审查" → review_strategy
   • --stop-on high / "严重问题停止" → stop_on_severity
   • --fix-attempts N / "修复N轮" / "给N次修复机会" → fix_attempts
   • --auto / --no-auto / "自动" / "手动确认" → auto_continue
   • --language Python / "用Go写" → language
   • --files x.py,y.py → context_files
   • --output-dir ./src → output_dir
   • --target-score 8.5 / "评分达到8.5时提醒" → target_score
   • --score-stability 2 / "连续2轮达标才停" → score_stability
   • --score-weights security-first / "安全优先" → score_weights
   • --defaults / "默认配置" / "全部默认" → use all defaults, skip step 0d
3. User's changes in step 0d below

0d. Present Defaults, Let User Adjust

If the user already said --defaults or "全部默认", skip this step.

Otherwise, show the current configuration (defaults merged with anything the user specified) and let them change anything:

The user can reply with:

• "go" / "开始" / "ok" — accept the current config and start
• Specific changes — e.g. "轮次5，加上architect和tester，每2轮审查，high停止，手动确认" → update those params in the config, show the updated table, then start
• More questions — answer them

Rules for showing this:

• If the user specified ALL parameters explicitly in their first message, you can skip this and proceed directly
• If anything is using a default, show this so the user knows what will happen
• Keep it one screen. Don't paginate.

0e. Coder Persona Rotation

Coder persona for each round (used in Phase 3):

Phase 1: Initialization

1. If output_dir is . (current directory), skip creation — agents work in-place within the existing project. Otherwise, create {output_dir}/.
2. Preview deterministic task state before creating pipeline directories. Put the exact request in a temporary UTF-8 file outside the target project and run python <skill-dir>/scripts/pipeline_state.py init --project {output_dir} --request-file <request-file> --max-rounds {max_rounds} --dry-run. This must not create .pipeline/ or any project file.
3. After checking the preview, rerun without --dry-run; the script creates .pipeline/tasks/ and the task files. Use --request only for short, non-sensitive requests. Delete only the temporary request file created for this initialization. Use the returned task ID. This records the initial commit, full status, changed-file hashes, and tracked binary diff under .pipeline/tasks/<task-id>/baseline.*.
4. Discover project validation commands — check for build/lint/test configuration (Makefile, package.json scripts, pyproject.toml, go.mod, etc.). Record discovered commands in .pipeline/project.json:

   {
     "language": "<detected>",
     "build_cmd": "<e.g. cargo build, go build ./...>",
     "lint_cmd": "<e.g. ruff check ., eslint .>",
     "test_cmd": "<e.g. pytest, go test ./...>",
     "type_check_cmd": "<e.g. mypy ., tsc --noEmit>",
     "security_cmd": "<e.g. bandit -r ., npm audit>",
     "formatter_cmd": "<e.g. black ., gofmt -w .>"
   }

5. Use the collision-resistant task ID generated by the state script (date-slug-requesthash, with a numeric suffix when needed).
6. Write .pipeline/config.json with all resolved parameters.
7. Treat the script-generated request.md, state.json, validation.json, baseline files, and task directories as authoritative. Do not recreate state.json manually. Use the script's update command for changes and validate before resume or completion.
8. Discover project structure — scan {output_dir}/ to build a file tree:
   • Use glob or ls to list all non-hidden files and directories (skip .pipeline/, .git/, node_modules/, __pycache__/, venv/, .venv/, *.pyc, etc.)
   • Store this tree at .pipeline/project_tree.txt for reuse across rounds.
   • If the directory is empty (greenfield project), note: "Empty project — you are writing the first files."

Note: requirements.md, spec.md, and architecture.md stay inside .pipeline/tasks/<task-id>/ by default. Only copy them to the project root if the user explicitly asks for project documentation.

Phase 2: Requirements Analysis (only if analyst in roles)

1. Update state: "phase": "analysis".
2. Read prompts/analyst.md.
3. Spawn agent (subagent_type: "general-purpose"):
   • Description: "Analyst: requirements analysis"
   • Prompt: role prompt + user's task + context_files
4. Wait for completion. Verify .pipeline/tasks/<task-id>/spec.md exists. Retry once if not.
5. Update state: "phase": "architecture" or "phase": "coding".

Phase 3: Architecture Design (only if architect in roles)

1. Update state: "phase": "architecture".
2. Read prompts/architect.md.
3. Spawn agent with role prompt + spec.md (or task if no analyst) + context_files.
   • Description: "Architect: system design"
4. Wait for completion. Verify .pipeline/tasks/<task-id>/architecture.md exists. Retry once if not.
5. Update state: "phase": "coding".

Phase 4: Coding Loop (the core)

For each round R from 1 to max_rounds:
    
    ┌─────────────────────────────────────────────┐
    │ 4a. Select persona & spawn coder            │
    │ 4b. Validate coder output                   │
    │ 4b2. Run validation (build/lint/test)       │
    │     ├─ checks pass? → continue              │
    │     └─ checks fail? → force Critic next     │
    │ 4c. Review decision → maybe run reviewer    │
    │ 4d. Check stop conditions                   │
    │     ├─ severity threshold met? → STOP EARLY │
    │     ├─ validation + review clean? → STOP    │
    │     ├─ progress stalled 2 rounds? → STOP    │
    │     └─ R == max_rounds? → STOP              │
    │ 4e. Update state, continue loop             │
    └─────────────────────────────────────────────┘

4a. Spawn Coder

1. Determine persona from the rotation table (0e).
2. Read the corresponding prompt file from prompts/.
3. Read the project tree from {output_dir}/.pipeline/project_tree.txt.
4. Collect current code from {output_dir}/ (skip .pipeline/, .git/, node_modules/, __pycache__/).
5. Compose prompt: role prompt + task context (task request, spec, architecture, project tree, current code, previous change_log, previous open_concerns, latest review findings, latest validation results).
6. Spawn agent:
   • Description: "Coder R{R}: {persona}"
   • subagent_type: "general-purpose"
7. Wait for completion.

4b. Validate Output

1. Check that code files were created/modified in {output_dir}/ (not in a random subdirectory outside the project).
2. Check .pipeline/tasks/<task-id>/change_log.md exists.
3. Check .pipeline/tasks/<task-id>/open_concerns.md exists.
4. Update .pipeline/project_tree.txt if the coder added new directories.
5. Reject unrelated churn, placeholder implementations, and edits outside scope. Inspect the diff.
6. Missing items? Ask agent to retry once. Second failure: warn and continue.

4b2. Run Validation (executable quality gate)

Per Reliability Rule #4: after every coding round, run applicable checks. Any failure returns to a Critic repair round.

1. Load .pipeline/project.json for discovered commands.
2. Run the narrowest relevant check first (e.g., formatter on changed files, then linter, then type-check, then build, then tests).
3. Record every command, its exit code, and concise failure output in .pipeline/tasks/<task-id>/validation.json:

   {
     "round": R,
     "checks": [
       {"cmd": "ruff check src/", "exit_code": 0, "status": "passed"},
       {"cmd": "pytest tests/ -q", "exit_code": 1, "status": "failed", "summary": "2 failed: test_login, test_register"}
     ],
     "overall": "failed"
   }

4. If any check fails:
   • Report: "Round {R}: validation failed — {N} check(s) did not pass."
   • Force the next round to use the Critic persona (regardless of rotation).
   • Feed the failure output as context.
5. If all checks pass: record and proceed normally.
6. If checks cannot run (e.g., no test runner configured for this language):
   • Record "status": "skipped" with reason.
   • Do NOT claim verification passed. This is verified_with_limitations at best.

4c. Review Decision

should_review = false
if review_strategy == "per_round":
    should_review = true
elif review_strategy == "batch":
    should_review = false   // only after the final round
elif review_strategy matches "milestone:N":
    should_review = (R % N == 0)

If should_review is true, run the reviewer now (Phase 5a).

4d. Check Stop Conditions (CRITICAL)

After review (or after coding if no review this round), evaluate in this order.

Tracking state (maintain across rounds):

• severity_hit_round: the round where the severity threshold was first hit (null if not hit yet)
• fix_rounds_used: how many fix-attempt rounds have been used since the hit
• stall_counter: how many consecutive rounds with zero net improvement
• validation_history: list of per-round validation results
• score_history: list of per-round scorecards

Condition 1: Severity Threshold Met → Enter Fix-Attempt Grace Period

If review ran and found issues at or above stop_on_severity:

severity_levels = { critical: 4, high: 3, medium: 2, low: 1, info: 0 }
threshold = severity_levels[stop_on_severity]  // "never" → Infinity
worst_finding = max severity across all findings

if worst_finding >= threshold:
    
    if fix_attempts == 0:
        STOP_REASON = "severity_threshold"
        Report and stop (see "Final Stop" below).
    
    else if severity_hit_round is None:
        severity_hit_round = R
        fix_rounds_used = 0
        Report: "Round {R}: {severity} issues found. Coder has {fix_attempts} round(s) to fix."
        Continue to next round.
    
    else:
        fix_rounds_used += 1
        
        if fix_rounds_used >= fix_attempts:
            STOP_REASON = "severity_threshold"
            Report: "Round {R}: {severity} issues persist after {fix_attempts} fix attempt(s). Stopping."
            Execute "Final Stop" below.
        else:
            remaining = fix_attempts - fix_rounds_used
            Report: "Round {R}: {severity} issues still present. {remaining} fix attempt(s) remaining."
            Continue to next round.

else:
    if severity_hit_round is not None:
        Report: "Round {R}: issues have dropped below {stop_on_severity} threshold. Grace period reset."
        severity_hit_round = None
        fix_rounds_used = 0

Final Stop (when fix_attempts exhausted or fix_attempts==0):

If auto_continue == true:
    Stop pipeline. Show summary.
    "Pipeline stopped at round {R}: {severity} severity issues persist."

If auto_continue == false:
    Present findings to user.
    Ask: "Continue fixing (next round), stop here, or ignore and finish?"
    - Continue → override stop, reset grace counter, continue
    - Stop → end pipeline
    - Ignore → skip remaining reviews, finish remaining rounds

Condition 2: Quality Gates Passed → STOP (Quality Achieved)

Per Reliability Rules #5-6: scores are advisory. The primary gate is executable validation passing + no unresolved critical/high findings + acceptance criteria satisfied.

all_checks_passed = every applicable check ran and exited successfully
checks_unavailable = one or more required checks could not run for a documented environmental reason
review_clean = review ran and found zero critical AND zero high issues
scores_are_advisory = true  // scores never block; they inform only

if all_checks_passed AND review_clean AND acceptance_criteria_satisfied:
    STOP_REASON = "quality_achieved"
    STATUS = "completed"
    Pipeline stops successfully.
    "Pipeline complete at round {R}: validation passes and review finds no critical/high issues."

if checks_unavailable AND review_clean AND acceptance_criteria_satisfied:
    STOP_REASON = "verification_limited"
    STATUS = "verified_with_limitations"
    Report exactly which checks could not run. Do not call this fully verified.

Score is advisory only. If composite score ≥ target_score, show a highlight in the report: "🎯 Advisory: score {score} meets target {target_score}" — but do NOT auto-stop on score alone. The scorecard is diagnostic; validation + findings are the real gate.

Condition 3: Progress Stalled → STOP

Per Reliability Rule #9: stop when progress stalls for two consecutive rounds.

A round has "no progress" when ALL of these are true:
  - validation result unchanged from previous round (same checks passed/failed)
  - no net reduction in open critical or high findings
  - composite score changed by ≤ 0.3 (negligible)

if round has "no progress":
    stall_counter += 1
    if stall_counter >= 2:
        STOP_REASON = "progress_stalled"
        Report: "Round {R}: no meaningful progress for 2 consecutive rounds. Stopping."
        Pipeline stops.
    else:
        Report: "Round {R}: minimal change detected. 1 more stalled round will trigger stop."
else:
    stall_counter = 0  // reset on any meaningful progress

Condition 4: Max Rounds Reached → STOP

If R == max_rounds (we just finished the last round):

STOP_REASON = "max_rounds"
Pipeline stops.
"Max rounds ({max_rounds}) reached."
If review found unresolved issues: mention them in the summary.

Condition 5: Continue

If none of the above triggered, continue to the next round.

Weight Presets (resolved at pipeline start, passed to Reviewer):

balanced:        all dimensions = 1.0
security-first:  security = 2.0, others = 1.0
performance-first: performance = 2.0, others = 1.0

Custom weights like security:3,performance:0.5 → unresolved dimensions default to 1.0.

4e. Update State & Loop

state.current_round = R
state.rounds_completed.push(R)

// Always record validation results
state.validation_history.push({
    "round": R,
    "result": validation.overall,  // "passed" | "failed" | "skipped"
    "checks": validation.checks
})

// Track stall detection
if no_progress_this_round:
    state.stall_counter += 1
else:
    state.stall_counter = 0

if review ran:
    state.last_review_round = R
    // Parse scorecard_round{R}.json and append to score_history
    score_entry = {
        "round": R,
        "composite": <parsed composite_score>,
        "dimensions": <parsed dimensions>,
        "critical": <count>, "high": <count>, "medium": <count>, "low": <count>
    }
    state.score_history.push(score_entry)

// Write state atomically to .pipeline/tasks/<task-id>/state.json
Continue to round R+1

Phase 5: Review Process

5a: Single Round Review

1. Read prompts/reviewer.md.
2. Read the project tree from {output_dir}/.pipeline/project_tree.txt.
3. Collect the current round diff, affected call paths, relevant tests, interfaces, and repository instructions. Expand to a repository-wide review only for cross-cutting or high-risk changes.
4. Resolve weights from score_weights parameter (use preset or parse custom weights).
5. Compute the weight values for each dimension.
6. Compose prompt: role prompt + project tree + code + spec + architecture + previous review reports + previous scorecards + "Use these dimension weights: security={w1}, correctness={w2}, performance={w3}, maintainability={w4}, robustness={w5}, completeness={w6}".
7. Spawn agent:
   • Description: "Reviewer: round {R}"
   • subagent_type: "general-purpose"
8. Wait for completion.
9. Verify .pipeline/tasks/<task-id>/reviews/review_round{R}.md was created.
10. Verify .pipeline/tasks/<task-id>/reviews/scorecard_round{R}.json was created. If missing, extract the JSON block from the review markdown and write it. If still missing, retry once.
11. Parse scorecard_round{R}.json to get composite_score and dimension scores.
12. Parse findings: count critical, high, medium, low issues.
13. Report to user: "Round {R} review: {C} critical, {H} high, {M} medium, {L} low — Score: {composite}/10"
14. Return findings and scores for stop condition check.

5b: Batch Review (only if review_strategy == "batch")

After the planned coding rounds:

1. Run a final review on the complete task diff and affected paths.
2. Write to .pipeline/tasks/<task-id>/reviews/review_final.md.
3. If accepted critical/high findings or validation failures remain, run up to fix_attempts Critic repair rounds, rerunning the exposing checks and final review after each repair.
4. Finish only through the normal quality gates. Batch review is never informational-only when it finds a release-blocking issue.

Phase 6: Testing (inside the coding loop)

Per Reliability Rule #7: testing is part of the coding loop, not a terminal phase. When tester is in roles, the tester runs within each round after the coder (and optionally after review).

6a: Test Writing (runs when behavior or coverage changes)

1. Read prompts/tester.md.
2. Spawn the tester only when a round adds behavior, fixes a regression, or reveals an explicit coverage gap. Always run existing relevant tests even when no tester agent is needed.
   • Description: "Tester R{R}: writing/updating tests"
   • subagent_type: "general-purpose"
3. Verify test files were created or updated.
4. Run the new tests immediately as part of 4b2 validation:
   • If tests fail → the failure enters the validation report → next round forced to Critic.
   • If tests pass → continue normally.
   • Do NOT treat test writing as a documentation-only artifact. Tests that don't run are useless.

6b: Tester-Only Mode (deprecated — testing always runs)

The old behavior (Tester runs once at the end) is replaced. If the user explicitly wants tests only after all coding, they should omit tester from roles and rely on the validation step (4b2) to run existing project tests.

Score Trend Chart Construction:

Build the ASCII bar chart from state.score_history:

1. Find the max composite score across all rounds.
2. For each round, render a bar: █ characters = floor(score), ░ characters = 10 - floor(score).
3. Show round number, bar, numeric score, persona, and top 3 dimension scores.
4. Calculate: start score (R1), final score (last R), absolute delta, percentage improvement.
5. Find the highest and lowest dimension averages across all rounds for the summary line.

If target_score was set and not met, show: ⚠️ 目标评分 {target_score} 未达到 (最终: {score})

If no reviews ran (e.g., batch strategy with no final review), skip the score section and show: (评分不可用 — 审查策略: batch 且未执行最终审查)

State Management

All pipeline state lives under .pipeline/. Task-specific state under .pipeline/tasks/<task-id>/:

{output_dir}/
├── .pipeline/                       # Pipeline metadata (hidden)
│   ├── project.json                 # Detected language + validation commands
│   ├── config.json                  # All resolved parameters
│   ├── project_tree.txt             # Discovered project structure
│   └── tasks/
│       └── <task-id>/               # Per-request isolation
│           ├── request.md           # Original task
│           ├── spec.md              # Analyst output (if enabled)
│           ├── architecture.md      # Architect output (if enabled)
│           ├── state.json           # Phase, round, findings, scores, stall

├── src/                             # Your actual code — in the real project
├── tests/                           # Your tests
└── ...                              # Your existing files

Key design decisions:

• .pipeline/ is the ONLY hidden directory added. Everything pipeline-related lives here.
• Task isolation — each user request gets its own tasks/<task-id>/ subdirectory. Resuming an unfinished task picks up where it left off.
• Per-task baseline.json and baseline.patch identify and preserve changes that existed before that task started.
• project.json caches discovered build/test commands so every round doesn't re-scan.
• No project-root pollution — requirements.md, spec.md, architecture.md stay inside .pipeline/tasks/<id>/ unless user explicitly asks for project documentation.
• All generated code goes where it naturally belongs based on the project structure.

Agent Communication

When composing a prompt for any agent, include:

## ROLE PROMPT
[full content of the appropriate prompts/*.md file]

## TASK CONTEXT
### Task
[.pipeline/tasks/<task-id>/request.md]

### Project Structure
[project_tree.txt content — this is the ACTUAL project layout. Place new files in the appropriate existing directories. Create new directories only when justified.]
IMPORTANT: You are working INSIDE this project, not in a sandbox. Your code files go where they naturally belong in this structure. Do NOT create an `output/` or `generated/` directory.

### Spec (if analyst ran)
[.pipeline/tasks/<task-id>/spec.md content]

### Architecture (if architect ran)
[.pipeline/tasks/<task-id>/architecture.md content]

### Current Code
[relevant code files from {output_dir}/ — use minimal context; don't send the whole repo]

### Previous Change Log
[.pipeline/tasks/<task-id>/change_log.md — or "Round 1, no previous changes"]

### Open Concerns
[.pipeline/tasks/<task-id>/open_concerns.md — or "None"]

### Review Findings to Address
[latest review report — or "No pending review findings"]

### Validation Results to Address
[latest validation.json — or "No pending validation failures"]

### Previous Scorecards
[previous scorecard JSON files — or "No previous scores"]

### Dimension Weights
[Resolved weights for each dimension. e.g.: security=1.0, correctness=1.0, performance=1.0, maintainability=1.0, robustness=1.0, completeness=1.0]

## OUTPUT INSTRUCTIONS
- Write code files into the EXISTING project structure shown above. Match the language/framework conventions.
- Write change log to .pipeline/tasks/<task-id>/change_log.md
- Write open concerns to .pipeline/tasks/<task-id>/open_concerns.md
- Follow your role's output format exactly
- Do NOT create a separate output directory for your code

Error Handling

Agent failure (API error, timeout, no output):

1. Retry once with same prompt.
2. Second failure:
   • Coder round 1: abort (no code to fall back on).
   • Coder round N>1: use round N-1 code, flag in summary.
   • Reviewer: skip review, warn user.
   • Analyst/Architect/Tester: skip phase, continue.

Missing output files:

1. Tell agent what's missing, retry once.
2. Second failure: apply fallback above.

User interruption mid-pipeline:

• .pipeline/tasks/<task-id>/state.json records last completed round.
• On restart, check for existing task state: "Found partial task <task-id> at round {N}. Resume or restart?"

Empty context_files:

• Verify each file exists. Warn and skip missing files.

Output directory already has content:

• If output_dir is . (current project): this is the NORMAL case. Just warn: "Working in current project. Existing files may be modified by agents." No need to block.
• If output_dir is a custom path: warn "Output directory exists. Files may be overwritten. Continue?"

Quick Reference

Key Rules

1. max_rounds can be any number. User picks it. Default is 5.
2. Pipeline stops on four conditions (whichever comes first):
   • Severity threshold exhausted (fix_attempts used up with issues still >= stop_on_severity)
   • Quality gates passed (validation passes + no critical/high findings)
   • Progress stalled (two consecutive rounds with no meaningful improvement)
   • Max rounds reached
3. Executable validation is the primary quality gate. Build/lint/test must pass. Reviewer scores are advisory diagnostics, not stop conditions.
4. All pipeline metadata lives in .pipeline/. Hidden from the project root. Per-task state under .pipeline/tasks/<task-id>/.
5. Testing is inside the loop. New tests run immediately. Failures re-enter the Critic repair round.
6. The Critic persona FIXES problems (not just reports them). The Reviewer REPORTS problems.
7. Coders hand off to each other. Each round's coder sees the previous round's code + change log + concerns + review findings + validation results.
8. State survives interruptions. Always check for .pipeline/tasks/<task-id>/state.json before starting. Resume unfinished tasks.
