<requirements> - Git repository with GitHub CLI (`gh`) installed and authenticated - Clean main/master branch - Proper permissions to create worktrees and access the repository - `bd` CLI installed for bead management </requirements> </execution_context>

<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>

<process>

1. Determine Review Target & Setup (ALWAYS FIRST)

Immediate Actions:

• [ ] Determine review type: bead ID (BD-xxx), PR number (numeric), GitHub URL, or empty (current in-progress bead)
• [ ] If bead ID provided: bd show {BEAD_ID} --json
• [ ] If no target: bd list --status in_progress --json | jq -r '.[0].id'
• [ ] Check current git branch
• [ ] If ALREADY on target branch -> proceed with analysis on current branch
• [ ] If DIFFERENT branch -> offer worktree: "Use git-worktree skill for isolated checkout." Call skill: git-worktree with branch name
• [ ] Fetch PR metadata via gh pr view --json for title, body, files, linked issues (if PR exists)
• [ ] Set up language-specific analysis tools
• [ ] Verify on the branch being reviewed

Code must be ready for analysis before proceeding.

2. Recall Relevant Knowledge

# Extract keywords from bead title/description
PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{keywords from bead title}"
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{tech stack keywords}"
"$PROJECT_ROOT/.lavra/memory/recall.sh" --recent 10

Present relevant LEARNED/DECISION/FACT/PATTERN entries for reviewers.

Protected Artifacts

The following paths are lavra pipeline artifacts and must never be flagged for deletion, removal, or gitignore by any review agent:

• .lavra/memory/knowledge.jsonl -- Persistent knowledge store
• .lavra/memory/knowledge.archive.jsonl -- Archived knowledge
• .lavra/memory/recall.sh -- Knowledge search script
• .lavra/config/project-setup.md -- Project configuration (read-only input to pipeline)
• .lavra/config/codebase-profile.md -- Codebase analysis (read-only input to planning pipeline)
• .lavra/config/lavra.json -- Workflow configuration (toggle research, review, goal verification)

If a review agent flags any file in .lavra/memory/ or .lavra/config/ for cleanup or removal, discard that finding during synthesis. Do not create a bead for it.

3. Read Project Config & Dispatch Review Agents in Parallel

3a. Read Project Config (optional)

PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")
[ -f "$PROJECT_ROOT/.lavra/config/project-setup.md" ] && cat "$PROJECT_ROOT/.lavra/config/project-setup.md"
[ -f "$PROJECT_ROOT/.lavra/config/lavra.json" ] && cat "$PROJECT_ROOT/.lavra/config/lavra.json"

From project-setup.md, parse YAML frontmatter for one field:

• review_agents: agent names to dispatch (replaces the default list below)

From lavra.json, parse model_profile (default: "balanced") and testing_scope (default: "full").

Model override rule: When model_profile is "quality", dispatch these critical agents with model: opus:

• security-sentinel
• architecture-strategist
• performance-oracle

All other agents run at their default tier regardless of profile.

Note: reviewer_context_note is intentionally not injected into review agents. Review agents derive project context from the code itself. Context note injection is only done in /lavra-work multi-bead path (pre-work conventions for implementors) where the value is clearer and the injection surface is smaller.

Agent discovery:

Discover all installed agents by scanning platform-appropriate directories, project-local first:

DISCOVERED_AGENTS=$(
  {
    # Project-local (all platforms)
    find .claude/agents .opencode/agents .cortex/agents hooks/agents -name "*.md" 2>/dev/null
    # Global / user-level
    find ~/.claude/agents ~/.config/opencode/agents ~/.cortex/agents -name "*.md" 2>/dev/null
    # Plugin source (fallback if nothing else found)
    find plugins/lavra/agents -name "*.md" 2>/dev/null
  } | xargs -I{} basename {} .md 2>/dev/null | grep -E '^[a-z][a-z0-9-]+$' | sort -u
)

This is the dispatch set when review_agents is absent. Project-local agents (including custom ones like rust-reviewer) are included automatically.

When review_agents is set in project-setup.md (explicit override):

Validate each name against DISCOVERED_AGENTS:

• Reject names not matching ^[a-z][a-z0-9-]*$ or not in DISCOVERED_AGENTS
• Silently skip invalid names
• If all entries are invalid, fall back to DISCOVERED_AGENTS

Config-missing behavior: If .lavra/config/project-setup.md absent, dispatch all DISCOVERED_AGENTS.

See references/default-agents.md for the agents Lavra ships and their purposes. That file is also a reference for building a review_agents config.

3b. Read Epic Plan (if provided)

If arguments include an ## Epic Plan block (injected by /lavra-work), extract Locked Decisions and store as {EPIC_LOCKED_DECISIONS}. Do not pass to review agents (biases toward plan over code). Use only in synthesis step (step 6) as a discard filter: if a flagged item appears in Locked Decisions, discard and note: "Discarded: planned item per epic Locked Decisions."

If no ## Epic Plan block present, {EPIC_LOCKED_DECISIONS} is empty and discard filter is a no-op.

3b2. Compute Diff Scope

If a PRE_WORK_SHA was passed in arguments (injected by lavra-work-multi Phase M8):

1. Extract the raw value from the PRE_WORK_SHA=... line in arguments
2. Validate against SHA format before use: reject if value does not match ^[0-9a-f]{7,40}$. If invalid, treat as absent and use the fallback below.
3. Compute introduced diff using the validated SHA:

# Only after validation passes:
# Use SHA without ..HEAD to include working-tree changes (required for lavra-work-multi,
# where wave changes are committed only after review).
INTRODUCED_DIFF=$(git diff "${PRE_WORK_SHA}")
DIFF_SCOPE_LABEL="${PRE_WORK_SHA}..WORKTREE"

If PRE_WORK_SHA is absent or failed validation, fall back to diffing against the branch base:

DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' || echo "main")
INTRODUCED_DIFF=$(git diff "origin/${DEFAULT_BRANCH}"...HEAD)
DIFF_SCOPE_LABEL="origin/${DEFAULT_BRANCH}...HEAD (branch base fallback)"

Guard against empty diff: If INTRODUCED_DIFF is empty after either path, surface a warning and prompt the user:

[lavra-review] WARN: Computed diff is empty — SHA may not be in local history, repo may be shallow, or there are no committed changes. Proceed with full file review instead, or cancel?

Do not silently dispatch agents with empty INTRODUCED_DIFF.

Store INTRODUCED_DIFF and DIFF_SCOPE_LABEL for use in agent dispatch and the summary report.

3c. Dispatch Agents in Parallel

Dispatch the agent list — review_agents from config if set and valid, otherwise DISCOVERED_AGENTS from Step 3a. Pass {INTRODUCED_DIFF} as the primary review input — not full file contents. Also pass the list of changed files:

CHANGED_FILES=$(git diff "${PRE_WORK_SHA}" --name-only 2>/dev/null || git diff "origin/${DEFAULT_BRANCH}"...HEAD --name-only)

Include this instruction in each agent prompt:

"Review only the code introduced in the diff below. A finding is pre-existing if the file it appears in is NOT in the changed files list. Context lines shown in the diff (unchanged lines starting with a space, not +) are NOT introduced — treat issues there as pre-existing. List pre-existing findings separately under ## Pre-existing Findings. Do not include them in your main findings list."

Pass {CHANGED_FILES} alongside {INTRODUCED_DIFF} so agents have a machine-checkable boundary.

For each agent in the dispatch set:

• Add model: opus if model_profile is "quality" AND agent name is one of: security-sentinel, architecture-strategist, performance-oracle
• Dispatch all agents in parallel: Task {agent-name}(INTRODUCED_DIFF)

Conditional Agents (run if applicable):

Run ONLY when PR matches specific criteria. Check PR files list:

If PR contains migrations or schema changes (any ORM):

13. Task data-migration-expert(INTRODUCED_DIFF) - Validates migration code correctness: ID mappings match production, checks for swapped values, verifies rollback safety, SQL verification
14. Task deployment-verification-agent(INTRODUCED_DIFF) - Creates Go/No-Go deployment checklist with SQL verification queries
15. Task migration-drift-detector(INTRODUCED_DIFF) - Detects schema/migration drift: verifies schema artifacts are in sync with migration history across Rails, Alembic, Prisma, Drizzle, and Knex

When to run migration agents:

• PR includes migration files matching any ORM pattern:
  • db/migrate/*.rb (Rails)
  • alembic/versions/*.py (Alembic)
  • prisma/migrations/*/migration.sql (Prisma)
  • drizzle/*/migration.sql (Drizzle)
  • migrations/*.js or migrations/*.ts (Knex)
• PR modifies schema artifacts:
  • db/schema.rb, prisma/schema.prisma, drizzle/meta/*.snapshot.json
• PR modifies columns that store IDs, enums, or mappings
• PR includes data backfill scripts
• PR changes how data is read/written
• PR title/body mentions: migration, backfill, data transformation, ID mapping

Agent roles are complementary:

• data-migration-expert: migration code correctness (SQL logic, rollback safety, ID mapping values)
• migration-drift-detector: migration consistency (schema artifacts in sync with migration history)

4. Ultra-Thinking Deep Dive Phases

Spend maximum cognitive effort on each phase. Think step by step. Question assumptions. Synthesize all reviews for the user.

Phase A: Stakeholder Perspective Analysis

<thinking> ULTRA-THINK: Put yourself in each stakeholder's shoes. What matters to them? What are their pain points? </thinking>

1. Developer Perspective

   • Easy to understand and modify?
   • APIs intuitive?
   • Debugging straightforward?
   • Testable?

2. Operations Perspective

   • Safe to deploy?
   • Metrics and logs available?
   • Troubleshooting path clear?
   • Resource requirements known?

3. End User Perspective

   • Feature intuitive?
   • Error messages helpful?
   • Performance acceptable?
   • Solves the problem?

4. Security Team Perspective

   • Attack surface?
   • Compliance requirements?
   • Data protected?
   • Audit capabilities?

Phase B: Scenario Exploration

<thinking> ULTRA-THINK: Explore edge cases and failure scenarios. What could go wrong? How does the system behave under stress? </thinking>

• [ ] Happy Path: Normal operation with valid inputs
• [ ] Invalid Inputs: Null, empty, malformed data
• [ ] Boundary Conditions: Min/max values, empty collections
• [ ] Concurrent Access: Race conditions, deadlocks
• [ ] Scale Testing: 10x, 100x, 1000x normal load
• [ ] Network Issues: Timeouts, partial failures
• [ ] Resource Exhaustion: Memory, disk, connections
• [ ] Security Attacks: Injection, overflow, DoS
• [ ] Data Corruption: Partial writes, inconsistency
• [ ] Cascading Failures: Downstream service issues

5. Simplification and Minimalism Review

Run the Task code-simplicity-reviewer() to see if we can simplify the code.

6. Findings Synthesis and Bead Creation

All findings from agents MUST be stored as beads. The filing path depends on whether the finding is in introduced code or pre-existing code. Create beads immediately after synthesis -- do NOT present for user approval first.

Step 1: Build Agent Finding Inventory

Build a complete inventory of what each agent returned. For each finding, classify it as introduced (in the diff) or pre-existing (in surrounding code not changed by this bead):

From kieran-rails-reviewer:
  [INTRODUCED] [finding 1], [finding 2], ...
  [PRE-EXISTING] [finding 3], ...
From dhh-rails-reviewer:
  [INTRODUCED] ...
  [PRE-EXISTING] ...
From security-sentinel:
  [INTRODUCED] ...
  [PRE-EXISTING] ...
... (one row per agent that ran)

Agents report pre-existing findings under ## Pre-existing Findings in their output. All other findings are treated as introduced.

Tiebreaking rule: If an agent's output contains a finding that is not clearly under ## Pre-existing Findings and the file it references is in {CHANGED_FILES}, treat it as introduced. If the file is NOT in {CHANGED_FILES}, treat it as pre-existing regardless of which section the agent placed it in. When file attribution is unclear, default to introduced — err toward blocking rather than silently deferring to triage.

Source of truth for synthesis. Do not proceed to Step 2 until every agent's output is listed.

Step 2: Synthesize All Findings

<thinking> Consolidate all agent reports into a categorized list of findings. Remove duplicates, prioritize by severity and impact. </thinking>

• [ ] Collect findings from the inventory, preserving introduced/pre-existing classification
• [ ] Discard findings recommending deletion/gitignore of files in .lavra/memory/ or .lavra/config/ (see Protected Artifacts)
• [ ] If {EPIC_LOCKED_DECISIONS} non-empty: for each finding flagging a field, struct, behavior, or data flow as unused/dead/unnecessary -- check Locked Decisions. If present, discard with note: "Discarded: planned item per epic Locked Decisions ({item name})."
• [ ] Categorize by type: security, performance, architecture, quality, etc.
• [ ] Assign severity: P1 CRITICAL, P2 IMPORTANT, P3 NICE-TO-HAVE
• [ ] Deduplicate -- data-migration-expert and migration-drift-detector may overlap; keep the more specific finding
• [ ] Estimate effort per finding (Small/Medium/Large)

Step 2a: Completeness Verification

Before creating beads:

• [ ] Every inventory finding is either included OR explicitly marked duplicate/inapplicable with reason
• [ ] Count: inventory total vs. categorized + discarded -- must reconcile
• [ ] Unaccounted items: categorize now

Do not proceed to bead creation until inventory fully accounted for.

Step 3: Create Beads for All Findings

Two filing paths depending on finding origin:

Path A — Introduced code findings: File as child beads of the reviewed bead. Blocking dependencies apply normally.

bd create "{finding title}" \
  --parent {BEAD_ID} \
  --type {bug|task|improvement} \
  --priority {1-5} \
  --tags "review,{category},{BEAD_ID}" \
  -d "## Issue
{Detailed description}

## Severity
{P1/P2/P3} - {Why this severity}

## Location
{file:line references}

## Why This Matters
{Impact and consequences}

## Validation Criteria
- [ ] {Test that must pass}
- [ ] {Behavior to verify}
{TEST_COVERAGE_CRITERIA}

## Testing Steps
1. {How to reproduce/test}
2. {Expected outcome}"

Path B — Pre-existing code findings: File as standalone beads with no parent and no blocking dependency on the current bead. Tag with pre-existing,review-sweep so they surface in triage.

bd create "{finding title}" \
  --type {bug|task|improvement} \
  --priority {1-5} \
  --tags "pre-existing,review-sweep,{category}" \
  -d "## Issue
{Detailed description}

## Origin
Pre-existing issue found during review of {BEAD_ID}. Not introduced by that bead. Does not block {BEAD_ID} from closing.

## Severity
{P1/P2/P3} - {Why this severity}

## Location
{file:line references}

## Why This Matters
{Impact and consequences}

## Validation Criteria
- [ ] {Test that must pass}
- [ ] {Behavior to verify}
{TEST_COVERAGE_CRITERIA}

## Testing Steps
1. {How to reproduce/test}
2. {Expected outcome}"

Pre-existing P1 findings still get filed — they are not discarded. But they do NOT block closing the current bead. They enter the triage queue for prioritization in a future work session.

Test coverage criteria injection ({TEST_COVERAGE_CRITERIA}):

Read testing_scope from lavra.json before creating beads.

• P1 findings (always, regardless of testing_scope): append to Validation Criteria:

  - [ ] Test added covering this scenario according to project test standards
  - [ ] Test fails before the fix, passes after
  

• P2 findings (only when testing_scope is "full"): append to Validation Criteria:

  - [ ] Test added covering this scenario according to project test standards
  

• P3 findings and P2 when testing_scope is "targeted": no test criteria appended.

When testing_scope is absent or unreadable, treat as "full".

Priority mapping:

• P1 CRITICAL -> priority 1
  • Introduced: blocks closing original bead
  • Pre-existing: filed standalone, does NOT block original bead
• P2 IMPORTANT -> priority 2 (should fix before closing, introduced only)
• P3 NICE-TO-HAVE -> priority 3-5 (can defer)

Step 4: Link Critical Issues

P1 findings in introduced code only: create blocking dependencies:

bd dep relate {FINDING_BEAD_ID} {ORIGINAL_BEAD_ID}

Do NOT create blocking dependencies for pre-existing findings. The original bead can close once its introduced code is clean.

Ensures the original bead cannot close until critical introduced-code issues are resolved.

Step 5: Mandatory Knowledge Capture (required gate -- do not skip)

Every P1/P2 finding must have at least one LEARNED, PATTERN, or MUST-CHECK entry before the summary. Captures root cause for future /lavra-design and /lavra-work auto-recall.

For each P1/P2 finding:

# Format: what was vulnerable/broken + root cause
bd comments add {BEAD_ID} "LEARNED: [component] was vulnerable to [issue] because [root cause]"
bd comments add {BEAD_ID} "PATTERN: [anti-pattern name] -- [where it appeared and why it's wrong]"

Examples:

• "LEARNED: UserController was vulnerable to XSS because params[:name] was interpolated into HTML without sanitize()"
• "PATTERN: N+1 query in OrdersController#index -- .includes(:line_items) was missing from the scope"
• "LEARNED: migration 20240301 swaps source/target column IDs -- production data uses the reverse mapping"

After logging LEARNED:, evaluate each P1 finding for structural escalation. Log a MUST-CHECK: entry when the finding meets any of these criteria:

• Same mistake appeared 2+ times (check prior waves or bead comments)
• Violation is silent — no test failure until production
• Security or isolation property that is not obvious from local code review

When any criterion applies, add a concise verification instruction (what to check before shipping, not just what went wrong):

bd comments add {BEAD_ID} "MUST-CHECK: {concise verification instruction — what to verify before shipping}"

Example pair:

LEARNED: RLS context is cleared by db.commit() in SQLAlchemy — SET LOCAL is transaction-scoped
MUST-CHECK: After any db.commit() inside a loop that uses RLS, verify set_rls_context() is called again before the next DB operation

Gate check: Run bd show {BEAD_ID} and verify that each P1/P2 finding has at least one LEARNED or PATTERN entry. MUST-CHECK entries are additional (for escalation-qualifying findings) and do not substitute for LEARNED/PATTERN. If any P1/P2 finding lacks a LEARNED or PATTERN entry, add it now. Do not proceed to summary until gate passes.

P3 findings may also have knowledge entries but are not required.

Step 6: Summary Report

## Code Review Complete

**Review Target:** {BEAD_ID} - {title}
**Branch:** {branch-name}
**Diff scope:** {DIFF_SCOPE_LABEL}

### Findings Summary:

**Introduced code (blocks {BEAD_ID} closure):**
- **P1 CRITICAL:** [count] - BLOCKS CLOSURE
- **P2 IMPORTANT:** [count] - Should Fix
- **P3 NICE-TO-HAVE:** [count] - Enhancements

**Pre-existing code (filed for triage, does NOT block {BEAD_ID}):**
- **P1 CRITICAL:** [count] - Filed standalone
- **P2 IMPORTANT:** [count] - Filed standalone
- **P3 NICE-TO-HAVE:** [count] - Filed standalone

### Created Beads — Introduced Code:

**P1 - Critical (BLOCKS CLOSURE):**
- {BD-XXX}: {description}

**P2 - Important:**
- {BD-XXX}: {description}

**P3 - Nice-to-Have:**
- {BD-XXX}: {description}

### Created Beads — Pre-existing (triage queue):

- {BD-XXX}: {description} [P1]
- {BD-XXX}: {description} [P2]

### Review Agents Used:
- {list of agents}

### Next Steps:

1. **Address P1 Findings in introduced code**: CRITICAL - must be fixed before closing
   - `/lavra-work {P1_BEAD_ID}` for each critical finding
2. **Close bead** (if no P1/P2 introduced findings): `bd close {BEAD_ID}`
3. **Resolve in parallel**: `/lavra-work {BEAD_ID}`
4. **Triage pre-existing findings**: `/lavra-triage` -- view with `bd list --tags "pre-existing,review-sweep"`
5. **View introduced findings**: `bd list --tags "review,{BEAD_ID}"`

7. End-to-End Testing (Optional)

Detect project type from PR files:

| Indicator | Project Type | |-----------|--------------| | *.xcodeproj, *.xcworkspace, Package.swift | iOS/macOS | | Gemfile, package.json, app/views/* | Web | | Both iOS files AND web files | Hybrid |

After the Summary Report, offer testing based on project type:

Web: "Want to run browser tests on the affected pages?"

1. Yes - run browser tests
2. No - skip

iOS: "Want to run Xcode simulator tests on the app?"

1. Yes - run Xcode tests
2. No - skip
