Bulwark brainstorm

Bulwark Brainstorm

Role-based brainstorming on a given topic with two execution modes:

• --scoped (default): Sequential Task tool pipeline — Project SME first, 3 role agents in parallel, Critical Analyst last. Best when the problem statement is well understood and you need focused implementation brainstorming.
• --exploratory: Agent Teams peer debate — Project SME first, then 3 AT teammates (Product & Delivery Lead, Architect, Critical Analyst) debating collaboratively. Best when validating whether an idea has merit and the problem framing is uncertain.

Both modes synthesize into a single brainstorm document with actionable recommendations.

Invocation arguments: $ARGUMENTS

When to Use This Skill

Load this skill when the user request matches ANY of these patterns:

Trigger Pattern	Example User Request
Implementation evaluation	"Should we build X?", "Evaluate this approach"
Feasibility assessment	"Is this feasible?", "How would we implement X?"
Architecture brainstorm	"Design the approach for X", "How should X fit into our system?"
Post-research planning	"We've researched X, now plan the implementation"
Role-based analysis	"Get PM/architect/dev perspectives on X"

DO NOT use for:

• Initial topic research (use bulwark-research first)
• Quick technical questions (ask directly)
• Code review (use code-review)
• Debugging (use issue-debugging)

---

Dependencies

Category	Files	Requirement	When to Load
Role definitions	references/role-*.md	REQUIRED	Load each before spawning its agent
Role output template	templates/role-output.md	REQUIRED	Include in PM, Architect, Dev Lead prompts
Critic output template	templates/critic-output.md	REQUIRED	Include in Critical Analyst prompt
Synthesis template	templates/synthesis-output.md	REQUIRED	Use when writing synthesis
Subagent prompting	subagent-prompting skill	REQUIRED	Load at Stage 1 for 4-part prompt template
AT teammate prompts	references/at-teammate-prompts.md	REQUIRED (--exploratory only)	Load at Stage 3B for AT prompt structure

Fallback behavior:

• If a role reference file is missing: Note in diagnostic log, skip that role, continue with remaining agents
• If output template is missing: Use the schema from this SKILL.md directly
• If research synthesis not provided: Agents work from problem statement alone (warn user that quality may be lower)

Mandatory Execution Checklist (BINDING)

Every item below is mandatory. No deviations. No substitutions. No skipping.

This skill uses a multi-stage pipeline. You are the orchestrator. Follow every item in order. Do NOT return to the user until all applicable items are checked.

• Stage 1 — Pre-Flight: Topic parsed (from argument, --doc, or AskUserQuestion)
• Stage 1 — Pre-Flight: subagent-prompting skill loaded
• Stage 1 — Pre-Flight: If topic is ambiguous or under-specified, AskUserQuestion interview conducted (2-3 questions per round)
• Stage 1 — Pre-Flight: If --research not provided, user warned via displayed message AND asked to confirm proceeding
• Stage 1 — Mode Detection: $CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS env var checked — you MUST check this, no exceptions
• Stage 1 — Mode Detection: If --exploratory requested AND env var NOT SET: notify user ("Agent Teams requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1. Using --scoped mode.") and fall back to --scoped
• Stage 1 — Mode Detection: If env var IS SET AND user requests --exploratory: AT Confirmation Flow executed (token cost warning + model class choice)
• Stage 1 — Mode Detection: If no mode flag provided: default to --scoped (do NOT auto-select AT even if env var is set)
• Stage 2 — Project SME: SME spawned via Task tool (general-purpose, Opus) and output read
• Stage 3A (--scoped): PM + Architect + Dev Lead spawned in parallel (3 Task tool calls), all outputs read
• Stage 3B (--exploratory): 3 AT teammates spawned in delegate mode with correct model class, all outputs read
• Stage 4 (--scoped only): Critical Analyst spawned with ALL prior outputs, output read
• Stage 5 — Synthesis: ALL role outputs read, synthesis written using template, AskUserQuestion for post-synthesis review
• Stage 5 — Evaluation Gate: Critical Evaluation Gate applied to all user responses
• Stage 6 — Diagnostics: Diagnostic YAML written to $PROJECT_DIR/logs/diagnostics/

Usage

/bulwark-brainstorm <topic-or-prompt> [--research <synthesis-file>] [--scoped | --exploratory]
/bulwark-brainstorm --doc <path-to-document> [--research <synthesis-file>] [--scoped | --exploratory]

Arguments:

• <topic-or-prompt> - Free-text topic description or problem statement
• --doc <path> - Use a document as the topic source
• --research <synthesis-file> - Path to Phase 1 research synthesis (from bulwark-research). Strongly recommended.
• --scoped - (default) Sequential Task tool mode with 5 roles. Use when the problem statement is well understood.
• --exploratory - Agent Teams peer debate with 4 roles. Use when validating whether an idea has merit. Requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.

Examples:

• /bulwark-brainstorm "agent teams" --research artifacts/research/agent-teams/synthesis.md - Scoped brainstorm with research (default mode)
• /bulwark-brainstorm --scoped "loop detection" - Explicit scoped mode
• /bulwark-brainstorm --exploratory "new plugin architecture" - Exploratory mode with AT peer debate
• /bulwark-brainstorm --doc plans/proposal.md --exploratory - Exploratory from a document

Stages

Stage 1: Pre-Flight

Stage 1: Pre-Flight
├── Read problem statement / document
├── Load research synthesis if --research provided
├── Parse mode flag: --scoped (default) or --exploratory
├── Mode detection (see below)
├── AskUserQuestion if ambiguous (iterative, 2-3 questions per round)
├── Slugify topic for output directory
├── Create output directories: $PROJECT_DIR/logs/brainstorm/{topic-slug}/ and $PROJECT_DIR/artifacts/brainstorm/{topic-slug}/
├── Load subagent-prompting skill
├── Load references/role-project-sme.md (needed for Stage 2)
└── Token budget check (warn if >30% for --scoped, >25% for --exploratory)

Mode Detection (MANDATORY — do NOT skip):

1. Check $CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS env var
2. Apply this decision matrix:

Env Var	User Flag	Action
NOT SET	No flag	--scoped (default)
NOT SET	--scoped	--scoped
NOT SET	--exploratory	Notify user: "Agent Teams requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1. Using --scoped mode." Fall back to --scoped.
SET	No flag	--scoped (do NOT auto-select AT)
SET	--scoped	--scoped
SET	--exploratory	Execute AT Confirmation Flow (see below)

AT Confirmation Flow (when --exploratory is selected and env var is set):

Display to user:

Exploratory mode uses Agent Teams peer debate and consumes ~2x tokens compared to --scoped mode.

3 AT teammates will debate collaboratively after the SME phase.

Model class for AT teammates:

• Opus — highest quality, higher token cost
• Sonnet — high quality, lower token cost (empirically validated)

[Proceed with Opus / Proceed with Sonnet / Switch to --scoped]

Record the user's model choice for Stage 3B teammate spawning.

AskUserQuestion Protocol (Pre-Spawn):

If the problem statement is ambiguous, under-specified, or could benefit from scope boundaries:

1. Ask 2-3 clarifying questions using AskUserQuestion
2. Assess whether the answers provide sufficient clarity to construct high-quality prompts
3. If not, ask up to 3 more questions in a follow-up round
4. Repeat until clarity is achieved (no hard cap on rounds, but each round is 2-3 questions max)
5. If the problem statement is clear and well-scoped from the start, skip this step and note in diagnostics: pre_flight_interview: skipped (problem statement sufficient)

If --research was not provided, warn the user: "No research synthesis provided. Brainstorm quality is significantly higher when preceded by /bulwark-research. Proceed without research?"

Stage 2: Project SME (Opus, Sequential — First)

Stage 2: Project SME
├── Load references/role-project-sme.md
├── Construct prompt using 4-part template
│   ├── GOAL: Establish project context relevant to the topic
│   ├── CONTEXT: Problem statement + research synthesis (if available)
│   └── OUTPUT: $PROJECT_DIR/logs/brainstorm/{topic-slug}/01-project-sme.md
├── Spawn general-purpose Opus agent
│   ├── Agent autonomously explores codebase (Glob, Grep, Read)
│   ├── NO hardcoded document paths — agent discovers what's relevant
│   └── Output documents which files were read and why
├── Read SME output
└── Token budget check

CRITICAL — SME Autonomy: The SME agent MUST NOT receive hardcoded project document paths. Instead:

• SME receives the problem statement and (optionally) research synthesis
• SME is spawned as general-purpose subagent type with Opus model
• SME autonomously explores the codebase using Glob, Grep, Read
• Instruct the SME: "Identify the MINIMUM files needed to answer: What exists relevant to this topic? Where are the integration points? What constraints apply? What must not be disrupted? Do NOT attempt to read the entire codebase."
• SME output documents which files it read and why

This makes the skill portable across any project.

Stage 3A: Role Analysis — Task Tool Mode (--scoped)

Execute this stage ONLY in --scoped mode. Skip entirely in --exploratory mode.

Stage 3A: Role Analysis (--scoped)
├── Load references/role-product-manager.md
├── Load references/role-technical-architect.md
├── Load references/role-development-lead.md
├── Load templates/role-output.md
├── Construct 3 prompts using 4-part template
│   ├── Each receives: problem statement + research synthesis + SME output
│   └── Each writes to: $PROJECT_DIR/logs/brainstorm/{topic-slug}/{NN}-{role-slug}.md
├── Spawn all 3 agents in parallel via Task tool
│   ├── subagent_type: general-purpose
│   ├── model: opus
│   └── All 3 in a single message (parallel)
├── Read all 3 outputs
└── Token budget check (checkpoint if >55%)

Output files (--scoped): 02-product-manager.md, 03-technical-architect.md, 04-development-lead.md

CRITICAL: Spawn all 3 agents in a single message with 3 Task tool calls. Do NOT spawn sequentially.

Stage 3B: Role Analysis — Agent Teams Mode (--exploratory)

Execute this stage ONLY in --exploratory mode. Skip entirely in --scoped mode.

In --exploratory mode, 5 roles collapse to 4. The PM and Dev Lead merge into a Product & Delivery Lead. The Critical Analyst joins as an active AT teammate (not a sequential gatekeeper), challenging positions in real time throughout the debate.

Stage 3B: Role Analysis (--exploratory)
├── Load references/role-product-delivery-lead.md
├── Load references/role-technical-architect.md
├── Load references/role-critical-analyst.md
├── Load templates/role-output.md
├── Load templates/critic-output.md
├── Enter delegate mode as lead
├── Spawn 3 AT teammates with user's chosen model class (Opus or Sonnet)
│   ├── Product & Delivery Lead
│   ├── Technical Architect
│   └── Critical Analyst
├── Each teammate prompt includes:
│   ├── Role reference content
│   ├── SME output (from Stage 2)
│   ├── Problem statement + research synthesis
│   ├── Dual-output contract (SA2)
│   ├── Peer debate directives
│   └── AT mitigation patterns (4 mandatory: CC-ALL, task list, completion signal, confirmation handshake)
├── Wait for all teammates to complete
├── Read all 3 output files from logs/
└── Token budget check (checkpoint if >45%)

Output files (--exploratory): 02-product-delivery-lead.md, 03-technical-architect.md, 04-critical-analyst.md

AT Teammate Prompt Structure, Configuration, and Failure Recovery

MANDATORY: Load references/at-teammate-prompts.md before constructing Stage 3B teammate prompts. It contains the full prompt structure (6 sections including dual-output contract, peer debate directives, 4 AT mitigation patterns, Critic deferred-verdict directive, and Lead Coordination Gates), AT configuration (hardcoded settings), and failure recovery procedures.

Stage 4: Critical Analyst — --scoped Mode ONLY (Opus, Sequential — Last)

Execute this stage ONLY in --scoped mode. In --exploratory mode, the Critical Analyst is a Stage 3B teammate — skip Stage 4 entirely.

Stage 4: Critical Analyst (--scoped only)
├── Load references/role-critical-analyst.md
├── Load templates/critic-output.md
├── Construct prompt using 4-part template
│   ├── CONTEXT includes ALL prior outputs:
│   │   ├── Problem statement + research synthesis
│   │   ├── SME output (01-project-sme.md)
│   │   ├── PM output (02-product-manager.md)
│   │   ├── Architect output (03-technical-architect.md)
│   │   └── Dev Lead output (04-development-lead.md)
│   └── OUTPUT: $PROJECT_DIR/logs/brainstorm/{topic-slug}/05-critical-analyst.md
├── Spawn general-purpose Opus agent
├── Read Critical Analyst output
└── Token budget check

CRITICAL: The Critical Analyst MUST receive ALL 4 prior outputs. This is the whole point — the Critic synthesizes and challenges everything.

Stage 5: Synthesis (SHARED — mode-aware)

Stage 5: Synthesis
├── Read ALL agent output files from logs/brainstorm/{topic-slug}/
│   ├── --scoped: expect 5 files (01-project-sme, 02-product-manager, 03-technical-architect, 04-development-lead, 05-critical-analyst)
│   └── --exploratory: expect 4 files (01-project-sme, 02-product-delivery-lead, 03-technical-architect, 04-critical-analyst)
├── Verify expected file count matches mode (5 for --scoped, 4 for --exploratory)
├── If any output is missing or empty → re-spawn that agent once (max 1 retry)
├── If retry fails → document gap in synthesis under "Incomplete Coverage"
├── Load templates/synthesis-output.md
├── Write synthesis to $PROJECT_DIR/artifacts/brainstorm/{topic-slug}/synthesis.md
│   └── Include mode field in YAML header (mode: scoped | exploratory)
├── AskUserQuestion for user on open questions (iterative, 2-3 per round)
├── Critical Evaluation Gate (see below)
└── Token budget check (must be <65% after synthesis)

Enforcement: Do NOT begin writing synthesis until ALL available agent outputs have been read. The orchestrator must reference every agent's output at least once in the synthesis.

Mode-specific synthesis notes:

• In --exploratory mode, the synthesis should capture debate dynamics — where teammates disagreed, what challenges were raised, and how positions evolved. Check for "Post-Debate Update" sections in agent outputs.
• In --scoped mode, synthesis follows the existing pattern (consensus areas, divergence areas, implementation outline).

Critical Evaluation Gate (Post-User Q&A)

After each AskUserQuestion round, do NOT blindly incorporate user responses. Instead:

Step 1 — Classify each user response:

Classification	Definition	Action
Preference	Scope, priority, or UX choice (e.g., "I'd prefer v1 to focus on X", "Let's defer Y")	Incorporate directly. These are user decisions — no validation needed.
Technical Claim	Assertion about a technology, library, or API (e.g., "Library X supports this", "That API has rate limits")	Do NOT incorporate. Trigger Step 2.
Architectural Suggestion	Proposed structural approach (e.g., "What if we structure it as a plugin?", "We could use event sourcing")	Do NOT incorporate. Trigger Step 2.

Step 2 — For Technical Claims and Architectural Suggestions, present to user:

"Your suggestion about [X] involves a technical claim / architectural approach that hasn't been validated against the codebase and research. I recommend a targeted follow-up with 2 focused agents (Technical Architect + Critical Analyst) to verify feasibility and stress-test the approach.

This will spawn 2 Opus agents and consume additional token budget.

[Run follow-up validation / Incorporate as-is with LOW confidence caveat]"

Step 3 — If follow-up validation approved:

1. Spawn 2 Opus agents in parallel (single message, 2 Task tool calls):
   • Technical Architect — validates the suggestion against the codebase and research: GOAL: Validate whether [{user_suggestion}] is technically feasible for this project. Include the Propose-Challenge-Refine reasoning depth instructions. Agent has access to Glob, Grep, Read for codebase exploration.
   • Critical Analyst — stress-tests the suggestion: GOAL: Challenge [{user_suggestion}]. Is this the simplest approach? What assumptions does it introduce? What would change the verdict? Include the Highest-Risk Assumption Focus reasoning depth instructions.
2. Use the same 4-part prompt template (GOAL/CONSTRAINTS/CONTEXT/OUTPUT)
3. Provide both agents with: original research synthesis, SME output, and the specific user suggestion
4. Output to: $PROJECT_DIR/logs/brainstorm/{topic-slug}/followup-{NN}-architect.md and followup-{NN}-critic.md
5. Read both outputs, then update synthesis with validated findings
6. Tag follow-up findings in synthesis with: [Follow-up: validated] or [Follow-up: refuted] or [Follow-up: mixed — see details]

Step 4 — If user declines follow-up:

Incorporate the user's suggestion into synthesis with an explicit caveat:

[Unvalidated — user suggestion, not verified against codebase or research]: {suggestion}

Repeat: After updating synthesis, ask if user has additional questions or input. Apply the same classification gate to each round. There is no limit on follow-up rounds, but each round with Technical Claim / Architectural Suggestion input that triggers validation consumes ~15-20% token budget (2 Opus agents) — warn user if approaching 55%.

Roles (Sections)

Each role brings a distinct professional perspective. Role availability depends on the execution mode.

Role Mapping by Mode

Role	--scoped	--exploratory
Project SME	Stage 2: Solo first (Task tool)	Stage 2: Solo first (Task tool) — identical
Senior Product Manager	Stage 3A: Parallel (Task tool)	Merged into Product & Delivery Lead
Senior Technical Architect	Stage 3A: Parallel (Task tool)	Stage 3B: AT teammate
Senior Development Lead	Stage 3A: Parallel (Task tool)	Merged into Product & Delivery Lead
Product & Delivery Lead	N/A	Stage 3B: AT teammate (combined PM + Dev Lead)
Critical Analyst	Stage 4: Sequential last (Task tool)	Stage 3B: AT teammate — active from start

Role 1: Project SME (Both Modes — Sequential First)

Purpose: Establish what exists, what has been built, and where the topic fits in the current architecture.

Focus Areas:

• Current project architecture relevant to the topic
• Existing assets that relate to or would be affected
• Integration points — where does this connect?
• Constraints imposed by current design decisions
• What the project already does well that must not be disrupted

Execution: Solo, first. Output feeds all subsequent agents. Identical in both modes.

Reference: references/role-project-sme.md

Role 2: Senior Product Manager (--scoped only)

Purpose: Evaluate user value, prioritization, and scope boundaries.

Focus Areas:

• User value proposition — who benefits and how?
• Prioritization — what delivers the most value soonest?
• Scope boundaries — what is v1 vs. deferred?
• Success criteria — how do we know this works?
• Risk to user experience if implemented poorly

Execution: Parallel with Architect and Dev Lead (Stage 3A). Receives SME output.

Reference: references/role-product-manager.md

Role 3: Senior Technical Architect (Both Modes)

Purpose: Define system design, patterns, and technical trade-offs.

Focus Areas:

• Architectural approach — how should this be structured?
• Design patterns that apply (and which to avoid)
• Technical trade-offs and their implications
• Integration architecture — how it connects to existing systems
• Extensibility and future-proofing considerations

Execution:

• --scoped: Parallel with PM and Dev Lead (Stage 3A). Receives SME output.
• --exploratory: AT teammate (Stage 3B). Receives SME output + peer debate.

Reference: references/role-technical-architect.md

Role 4: Senior Development Lead (--scoped only)

Purpose: Assess implementation feasibility, effort, and practical risks.

Focus Areas:

• Implementation feasibility — can this be built with available tools?
• Effort estimation — complexity and session count
• Implementation risks — what could go wrong during building?
• Testing strategy — how do we verify this works?
• Dependencies and ordering — what must be built first?

Execution: Parallel with PM and Architect (Stage 3A). Receives SME output.

Reference: references/role-development-lead.md

Role 5: Product & Delivery Lead (--exploratory only)

Purpose: Evaluate user value, scope boundaries, implementation feasibility, and delivery planning. Combines PM's value/prioritization lens with Dev Lead's feasibility/effort lens.

Focus Areas:

• User value proposition and prioritization
• Scope boundaries — v1 vs. deferred
• Implementation feasibility and effort estimation
• Build order, dependencies, testing strategy
• Value-effort trade-offs — which features have the best ROI?

Execution: AT teammate (Stage 3B). Receives SME output + peer debate.

Reference: references/role-product-delivery-lead.md

Role 6: Critical Analyst (Both Modes — Different Execution)

Purpose: Perform cost-benefit analysis, challenge assumptions, validate the problem itself, poke holes.

Focus Areas:

• Problem validation — should this problem be solved at all?
• Cost-benefit analysis — is the investment justified?
• Assumption challenges — what might be wrong?
• Gaps in the proposals — what has been overlooked?
• Simpler alternatives — could a less ambitious approach work?
• Kill criteria — under what conditions should this be abandoned?
• Final verdict: proceed / modify / defer / kill

Execution:

• --scoped: Solo, last (Stage 4). Receives ALL prior outputs. Maximum information, zero influence on the analysis process.
• --exploratory: AT teammate (Stage 3B). Active from start. Challenges in real time. Partial information early, maximum influence on debate. Deferred verdict.

Reference: references/role-critical-analyst.md Output template: templates/critic-output.md (has verdict + problem validation sections)

Token Budget Management

Checkpoint	--scoped Threshold	--exploratory Threshold	Action
After constructing SME prompt	>30% consumed	>25% consumed	Warn user about agent token cost
After reading Stage 3A/3B outputs	>55%	>45%	Checkpoint with user
After synthesis	Must be <65%	Must be <65%	Leave room for session closing
Synthesis complete at >65%	Immediate	Immediate	Create handoff, do not start additional work

--exploratory costs ~2x tokens due to AT peer debate overhead. The lower thresholds account for this.

If token budget is insufficient to complete all agents + synthesis, inform the user and suggest splitting (e.g., "SME + role analysis this session, synthesis next session").

---

Error Handling

Scenario	Action
Agent returns empty output	Re-spawn once. If still empty, document gap in synthesis.
Agent returns truncated output	Accept as-is, note in diagnostics.
Agent fails to spawn	Re-spawn once. If still fails, skip role, document.
SME fails	STOP — subsequent agents depend on SME. Inform user.
Token budget exceeded mid-session	Stop spawning, synthesize from available outputs, note incomplete.
Research synthesis not provided	Warn user, proceed with lower quality.
AT teammate fails mid-debate (--exploratory)	Fall back to Stage 3A for failed role only. Partial AT output from successful teammates feeds into fallback as additional context.
All AT teammates fail (--exploratory)	Fall back to full Stage 3A (--scoped pipeline). Document in diagnostics.
AT lead context compaction (--exploratory)	Known platform limitation. SME running before AT is the structural mitigation. Document in diagnostics if observed.
--exploratory requested, env var not set	Notify user, fall back to --scoped. Not an error — graceful degradation.

---

Diagnostic Output (REQUIRED)

MANDATORY: You MUST write diagnostic output after every invocation. This is Stage 6 and cannot be skipped.

Write to: $PROJECT_DIR/logs/diagnostics/bulwark-brainstorm-{YYYYMMDD-HHMMSS}.yaml

Template: Use templates/diagnostic-output.yaml for the schema. Fill in actual values from the session.
