<objective>
Execute work on beads efficiently while maintaining quality and finishing features. Auto-routes between single-bead direct execution, sequential epic execution (token-efficient), and multi-bead parallel dispatch based on input. For autonomous retry, use `/lavra-work-ralph`. For persistent worker teams, use `/lavra-work-teams`.

## Phase 0: Parse Arguments and Auto-Route

### 0a. Parse Arguments

Parse flags from the `$ARGUMENTS` string:

- `--yes`: skip user approval gate (but NOT pre-push review)
- `--parallel`: force parallel multi-bead mode, skip sequential gate
- `--no-parallel`: force sequential mode, skip sequential gate

Remaining arguments (after removing flags) are the bead input: a single bead ID, an epic bead ID, comma-separated IDs, a specification path, or empty.

### 0b. Permission Check

**Only when running as a subagent** (BEAD_ID was injected into the prompt):

Check whether the current permission mode will block autonomous execution. Subagents need Bash, Write, and Edit tool access without human approval.

If tool permissions appear restricted:
- Warn: "Permission mode may block autonomous execution. Subagents need Bash, Write, and Edit tool access without human approval."
- Suggest: "For autonomous execution, ensure your settings.json allows Bash and Write tools, or run with --dangerously-skip-permissions."

This is a warning only -- continue regardless.

### 0c. Determine Routing

Count beads to decide which path to take:

**If a single bead ID or specification path was provided:**
- Route = SINGLE

**If an epic bead ID was provided:**
```bash
bd list --parent {EPIC_ID} --status=open --json
```
- If 1 bead returned: Route = SINGLE (with that bead)
- If N > 1 beads returned: Route = MULTI_CANDIDATE (ask sequential gate below)

**If a comma-separated list of bead IDs was provided:**
- If 1 ID: Route = SINGLE
- If N > 1 IDs: Route = MULTI_CANDIDATE

**If nothing was provided:**
```bash
bd ready --json
```
- If 0 beads: inform user "No ready beads found. Use /lavra-design to plan new work or bd create to add a bead." Exit.
- If 1 bead: Route = SINGLE (with that bead)
- If N > 1 beads: Route = MULTI_CANDIDATE

### 0d. Sequential Gate (MULTI_CANDIDATE only)

Skip this step if Route = SINGLE, or if `--parallel` or `--no-parallel` was provided.

Ask the user:

> **{N} beads ready. How do you want to work?**
>
> 1. **Sequential** (recommended) — Work beads one at a time in this context. Lower token cost, easier to follow. Review runs once at the end.
> 2. **Parallel** — Dispatch subagents per bead simultaneously. Faster wall clock, higher token cost.

- User chooses 1 → Route = SEQUENTIAL
- User chooses 2 → Route = MULTI
- `--no-parallel` flag → Route = SEQUENTIAL (skip gate)
- `--parallel` flag → Route = MULTI (skip gate)

## Routing

After determining Route in Phase 0c/0d:

- **SINGLE:** `Skill("lavra-work-single")`
- **SEQUENTIAL:** Sequential Epic Loop (see below)
- **MULTI:** `Skill("lavra-work-multi")`

---

## Sequential Epic Loop

Work beads one at a time in the main agent context. No subagent spawning. `lavra-review` runs once after all beads complete.

### Step 1: Build ordered bead list

```bash
bd list --parent {EPIC_ID} --status=open --json   # for epics
# or use the comma-separated / bd ready list directly
```

Order by dependency: beads with no blockers first. For each bead, check `bd dep list {BEAD_ID} --json` and sort so no bead runs before its dependencies are closed.

Store as `{SEQUENTIAL_BEAD_LIST}`.

### Step 2: Read epic context (if epic)

```bash
bd show {EPIC_ID}
```

Extract `## Locked Decisions`, `## Agent Discretion`, and `## Deferred` sections. Pass to each single-bead iteration as `{EPIC_PLAN}`.

### Step 3: Loop — implement each bead

For each bead in `{SEQUENTIAL_BEAD_LIST}`:

```
Skill("lavra-work-single", "{BEAD_ID} --skip-review EPIC_PLAN={EPIC_PLAN}")
```

The `--skip-review` flag tells `lavra-work-single` to skip its internal `/lavra-review` call. Self-review (Phase 3 step 2) still runs. Review happens once at the end of the loop.

After each bead completes, check if it was closed. If it was not (user deferred), continue to the next bead anyway — do not block the loop.

Update session state after each bead:

```bash
PROJECT_ROOT="${PROJECT_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")}"
cat > "$PROJECT_ROOT/.lavra/memory/session-state.md" << EOF
# Session State
## Current Position
- Epic: {EPIC_ID}
- Mode: sequential
- Progress: {N_DONE} of {N_TOTAL} beads complete
## Just Completed
- {BEAD_ID}: {bead title}
## Remaining
- {list of remaining bead IDs and titles}
EOF
```

### Step 4: End-of-epic review

After all beads in `{SEQUENTIAL_BEAD_LIST}` are processed, run a single review pass over all introduced changes:

```bash
DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' || echo "main")
PRE_WORK_SHA=$(git merge-base HEAD "origin/${DEFAULT_BRANCH}")
```

```
Skill("lavra-review", "{space-separated BEAD_IDs}

PRE_WORK_SHA={PRE_WORK_SHA}

## Epic Plan (read-only — reviewers must not flag planned-but-incomplete items as dead code)
{EPIC_PLAN}

Locked Decisions in the epic above are intentional, even if a field or behavior appears unused or partially wired. Do not create beads recommending removal of items that appear in Locked Decisions.")
```

Apply inline-fix triage to findings (same rules as single-bead Fix Loop): fix P3/cosmetic/single-location issues inline, create beads for P1/P2/multi-file findings.

### Step 5: Summary

```
## Sequential Epic Complete

**Epic:** {EPIC_ID} - {title}
**Beads worked:** {N}
**Review:** {N} findings, {N_inline} fixed inline, {N_beads} filed as beads

### Beads Worked:
- {BD-XXX}: {title} — closed | deferred
- ...

### Next Steps:
1. Address any P1 review findings: `/lavra-work {FINDING_BEAD_ID}`
2. Open PR: `/lavra-ship`
3. View filed findings: `bd list --tags "review"`
```

---

## Shared Guarantees

Both downstream paths inherit these operational guarantees regardless of route:

- **Deviation Rules:** implementers log out-of-scope fixes as `DEVIATION:` entries rather than silently folding them into the bead.
- **Goal Verification:** before closing work, run the `goal-verifier` review agent.
- **Session Handoff:** execution paths update `.lavra/memory/session-state.md` so compaction or interruption can resume cleanly.
- **Commit Policy:** execution reads `commit_granularity` from `.lavra/config/lavra.json` and follows that commit cadence.
- **Decision categories:** bead instructions are interpreted through the `Locked`, `Discretion`, and `Deferred` categories defined in the planning workflow.
