Take an existing plan (from `/lavra-plan` or `/lavra-design`) and GATHER evidence for each section using domain-matched research agents. Each agent is selected because its expertise matches the plan's technologies and concerns. Research GATHERS findings (docs, prior art, best practices, edge cases, knowledge recall) -- it does NOT revise the plan or apply changes. That is `/lavra-design`'s job. The output is organized research findings ready for `/lavra-design` to integrate.

#$ARGUMENTS

If the epic bead ID above is empty:

1. Check for recent epic beads: bd list --type epic --status=open --json
2. Ask the user: "Which epic would you like to research? Please provide the bead ID (e.g., BD-001)."

Do not proceed until you have a valid epic bead ID. </execution_context>

**The current year is 2026.** Use this when searching for recent documentation and best practices.

<project_root>

All .lavra/ paths are relative to the project root. If you cd into a subdirectory during work, resolve the project root first:

PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")

Then prefix all .lavra/ paths with "$PROJECT_ROOT/" when invoking them via Bash.

</project_root>

1. Parse Plan and Extract Domain Indicators

Read the epic and its children to understand what the plan is about. Extract domain indicators that will drive agent selection.

Read the epic and its children:

bd show {EPIC_ID}
bd list --parent {EPIC_ID} --json

For each child bead, read its description:

bd show {CHILD_ID}

Extract domain indicators from the plan content:

Scan all bead titles, descriptions, acceptance criteria, and code references for:

• Languages: Ruby, Python, TypeScript, JavaScript, Go, Rust, etc.
• Frameworks: Rails, Django, React, Next.js, FastAPI, etc.
• Concerns: security, auth, performance, migrations, data integrity, deployment, frontend/CSS/JS, design/UI/UX
• File types: .rb, .py, .ts, .tsx, .sql, .css, etc.
• Infrastructure: databases, APIs, CI/CD, Docker, cloud services

Build a domain profile:

Languages: [detected languages]
Frameworks: [detected frameworks]
Concerns: [detected concerns]
File types: [detected file types]
Infrastructure: [detected infrastructure]

2. Select Research Agents by Domain Match

Match agents to the plan's domain profile. Only dispatch agents whose expertise is relevant. This avoids wasting tokens on agents that have nothing to contribute.

Always include these agents (universal relevance):

• architecture-strategist -- structural concerns apply to every plan
• code-simplicity-reviewer -- complexity is always worth checking
• best-practices-researcher -- general best practices research
• framework-docs-researcher -- documentation lookup for detected frameworks
• learnings-researcher -- search knowledge.jsonl for past solutions

Conditionally include based on domain indicators:

Domain indicator	Agent(s) to include
Database, migrations, schema, SQL, models	data-migration-expert, data-integrity-guardian, migration-drift-detector
Frontend, CSS, JS, React, UI components	julik-frontend-races-reviewer, design-implementation-reviewer
Rails, Ruby, .rb files	dhh-rails-reviewer, kieran-rails-reviewer
Python, Django, FastAPI, .py files	kieran-python-reviewer
TypeScript, .ts/.tsx files	kieran-typescript-reviewer
Security, auth, OAuth, tokens, encryption	security-sentinel
Performance, caching, N+1, latency	performance-oracle
Deployment, CI/CD, Docker, infrastructure	deployment-verification-agent
Design, UI/UX, Figma, layout	design-iterator, figma-design-sync
Patterns, architecture, abstractions	pattern-recognition-specialist
Agent-native, AI workflows, LLM	agent-native-reviewer
Git history, blame, refactor archeology	git-history-analyzer
Repository structure, codebase analysis	repo-research-analyst

Build the agent roster with justifications:

SELECTED AGENTS:
- architecture-strategist (always included)
- code-simplicity-reviewer (always included)
- best-practices-researcher (always included)
- framework-docs-researcher (always included)
- learnings-researcher (always included)
- dhh-rails-reviewer (plan mentions Rails controllers and models)
- security-sentinel (plan includes OAuth token handling)
- data-migration-expert (plan adds new database columns)
...

Present this roster to the user before dispatching. No confirmation needed -- show it so they know what is running.

3. Discover Relevant Skills

Scan available skills and note which ones are relevant. Don't spawn a sub-agent per skill -- just search and list.

# Project-local skills
ls .claude/skills/ 2>/dev/null

# User's global skills
ls ~/.claude/skills/ 2>/dev/null

For each skill directory found, read its SKILL.md and check if it matches the plan's domain. Build a list:

RELEVANT SKILLS:
- dhh-rails-style: Plan uses Rails conventions (matched: Rails framework)
- frontend-design: Plan includes UI components (matched: frontend concern)

List these for agents to reference, but do NOT spawn separate skill sub-agents.

4. Search Knowledge Base

Search for relevant past learnings before dispatching agents. These inform what we already know.

Search for relevant learnings:

# Search knowledge for each key topic in the plan
PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{topic 1}"
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{topic 2}"
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{technology}"

# Search with --all to include archived knowledge
"$PROJECT_ROOT/.lavra/memory/recall.sh" --all "{broad topic}"

Collect all relevant entries. These will be provided to agents as context.

5. Dispatch Selected Agents in Parallel

Launch ONLY the selected agents from Step 2. Each agent gets the full plan content plus relevant knowledge entries. Agents GATHER findings -- they do not revise the plan.

For each selected agent, launch in parallel:

Task [agent-name]: "Research this plan using your expertise. GATHER evidence only -- do not revise the plan.

DOMAIN MATCH REASON: [why this agent was selected]

PLAN CONTENT:
[full plan content from epic + children]

RELEVANT KNOWLEDGE ENTRIES:
[any matching entries from Step 4]

RELEVANT SKILLS:
[any matching skills from Step 3]

YOUR JOB:
1. Apply your expertise to identify: best practices, risks, edge cases, patterns, anti-patterns, performance considerations
2. Cite sources where possible (docs, prior art, knowledge entries)
3. Return CONCRETE findings organized by child bead
4. Flag any concerns or risks with severity (high/medium/low)

DO NOT rewrite the plan. Just report what you found."

Launch ALL selected agents in a SINGLE message with multiple Task calls.

6. Collect and Organize Findings

Wait for all agents to complete. Organize findings by child bead, not by agent.

Collect outputs from all agents and organize by child bead:

BEAD {CHILD_ID}: {title}

  architecture-strategist:
    - [finding 1]
    - [finding 2]

  security-sentinel:
    - [finding 1 - severity: high]

  best-practices-researcher:
    - [finding 1 with source URL]

Deduplicate: Merge identical recommendations from multiple agents. Flag conflicts: If two agents disagree, note both perspectives. Prioritize: Mark high-impact findings.

7. Log Research Findings as Knowledge Comments

Capture key findings as knowledge comments on the relevant beads. This is the primary output -- structured evidence for /lavra-design to consume.

For each child bead with findings:

bd comments add {CHILD_ID} "INVESTIGATION: [key research finding with source]"
bd comments add {CHILD_ID} "FACT: [constraint or gotcha discovered]"
bd comments add {CHILD_ID} "PATTERN: [recommended pattern with rationale]"

Add a research summary to the epic:

bd comments add {EPIC_ID} "INVESTIGATION: Research completed with [count] domain-matched agents ([agent names]). Key findings: [top 3 findings]. Ready for /lavra-design to integrate."

<success_criteria>

• Domain indicators correctly extracted from plan content
• Only domain-relevant agents dispatched (with justification for each)
• All agent findings organized by child bead
• Key findings logged as INVESTIGATION/FACT/PATTERN comments
• Research summary added to epic bead
• NO plan modifications made -- findings only </success_criteria>

- NEVER modify child bead descriptions. Research GATHERS evidence. `/lavra-design` APPLIES it. - NEVER write code. Just research and report findings. - NEVER dispatch agents that have no domain match. Each agent must have a stated reason for inclusion. After logging all findings, use the **AskUserQuestion tool** to present these options:

Question: "Research complete for epic {EPIC_ID}. [count] agents gathered findings across [count] child beads. What would you like to do next?"

Options:

1. Run /lavra-design - Integrate research findings into the plan
2. Run /lavra-eng-review - Get feedback from reviewers on the plan
3. Research deeper - Run another round on specific sections with additional agents
4. View findings - Show all research findings organized by child bead

Based on selection:

• /lavra-design -> invoke Skill("lavra-design") with the epic bead ID
• /lavra-eng-review -> invoke Skill("lavra-eng-review") with the epic bead ID
• Research deeper -> Ask which sections need more research, add targeted agents
• View findings -> Show findings grouped by child bead with agent attribution
