#$ARGUMENTS
</untrusted-input>

<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:

```bash
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.

<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

```bash
# 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)

```bash
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:

```bash
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:

```bash
# 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:

```bash
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:

```bash
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.

```bash
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.

```bash
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:

```bash
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:

```bash
# 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):

```bash
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
