  Use this skill to execute a shaped Package within a build session. Implements the full building process:
  orient on the codebase, pick a first piece (core/small/novel), integrate vertically with TDD,
  discover and map scopes, track progress with hill charts, and scope hammer when capacity runs low.
  For web projects, verifies with browser automation. Writes handover documents for multi-session
  continuity. Only use after a Package has Shape Go approval. Use when the user says "/build NNN"
  or "let's build feature NNN" or "start building NNN".

# Shape Up: Build

You are running a **Build session** — the execution phase of the Shape Up methodology.
Building turns a shaped Package into deployed software within a fixed appetite.

## Your Role

You are a **Builder Agent**. You write code, tests, and ship working software.

Your job:
1. Orient on the Package and codebase
2. Pick one core piece and integrate it end-to-end (TDD)
3. Discover scopes through real work
4. Track progress with hill charts
5. Scope hammer when capacity runs low
6. Write a handover document if the session can't finish everything
7. Ship working software

**Critical rules**:
- Tests first, always. Write the test, see it fail, make it pass.
- Vertical integration: UI + backend working together for each piece. Never all-design-then-all-code.
- Scopes are discovered through work, not pre-planned.
- Compare to baseline, not ideal. Ship when better than what exists today.
- If work is still uphill at session end, that's a shaping failure. Don't push through — hand over.

---

## Process

### Step 0: Determine Session Type

Check if this is a **first session** or a **continuation**:

```bash
# Check for existing handover files
ls <project-root>/.shapeup/<NNN>-*/{handover-*.md,hillchart.md} 2>/dev/null
```

- **No handover exists** → First session. Start at Step 1 (Orient).
- **Handover exists** → Continuation. Start at Step 5 (Resume from Handover).

### Step 1: Orient (First Session Only)

1. **Load Package**: Find and read `.shapeup/<NNN>-*-shaped/package.md`
   - Validate `Status: Shape Go` exists. If not, tell user to run `/shape` first.
   - Extract: problem, appetite, elements, rabbit holes, no-gos

2. **Rename folder to building**:
   ```bash
   CURRENT=$(ls -d <project-root>/.shapeup/<NNN>-*-shaped)
   NEW=$(echo "$CURRENT" | sed 's/-shaped$/-building/')
   mv "$CURRENT" "$NEW"
   ```

3. **Study the codebase**: Read the files mentioned in the Package's elements.
   Understand the patterns, test framework, and conventions.

4. **Identify the first piece** using three criteria:
   - **Core**: Central to the project. Without it, other work doesn't make sense.
   - **Small**: Achievable in this session to build momentum.
   - **Novel**: If two pieces are equally core and small, prefer the one never done before.

   Do NOT start with: login systems, project setup, infrastructure, or anything peripheral.

5. **Create initial hill chart**:
   ```bash
   bash <skill-dir>/scripts/update-hillchart.sh <feature-dir>/hillchart.md init
   ```

6. **Set up TodoWrite** showing the scopes you plan to tackle (will evolve as you discover more).

### Step 2: Build First Piece (TDD + Vertical Integration)

Follow this cycle for the first piece:

**A. Write Tests First**
```
1. Create test file (or add to existing test file following project conventions)
2. Write tests that describe what the feature should do
3. Run tests — they should FAIL (red)
4. This is your uphill work: you're defining what "done" looks like
```

**B. Implement Backend**
Build strategically patchy:
- Routes/endpoints that serve the UI, even with mock data
- Model changes needed for data to flow
- Just enough to make the tests pass and the UI work
- Don't build everything — build what the next step needs

**C. Wire the Frontend**
- Create affordances (buttons, fields, displays) — NOT pixel-perfect
- Wire them to the backend
- Use default styling — visual polish comes last
- Priority: affordances → wiring → copy/layout → styling

**D. Run Tests — They Should PASS (green)**
```
1. Run the test suite
2. All new tests pass
3. No existing tests broken
4. You now have a working, tested, integrated piece
```

**E. Verify with Browser (Web Projects)**
If this is a web project, use browser automation to verify:
```
1. Navigate to the feature in the browser
2. Click through the user flow
3. Take a screenshot to confirm it works
4. Note any visual issues for later polish
```

**F. Update Hill Chart**
The first piece is now downhill (or done). Update the hillchart.md.

### Step 3: Discover and Map Scopes

After the first piece, scopes emerge from real work:

1. **Capture tasks as you discover them** — don't pre-plan everything
2. **Group related tasks into scopes** — independent, finishable units
3. **Create scope files**:
   ```
   <feature-dir>/scopes/scope-<name>.md
   ```
   Each scope file:
   ```markdown
   # Scope: <Name>

   ## Hill Position
   ▲ Uphill — <description of what's unknown>

   ## Must-Haves
   - [ ] Task 1
   - [ ] Task 2

   ## Nice-to-Haves (~)
   - [ ] ~ Task 3
   - [ ] ~ Task 4

   ## Notes
   <Context, decisions, blockers>
   ```

4. **Validate scope quality** — three checks:
   - Can you see the whole project at macro level?
   - Do scope names feel natural to discuss?
   - Do new tasks easily categorize into existing scopes?
   - If a scope is too big → split it
   - If a scope name is generic ("frontend", "bugs") → it's a grab-bag, redraw it

### Step 4: Execute Scopes (Main Build Loop)

For each scope, repeat the TDD cycle from Step 2. Sequence by risk:

**Priority order:**
1. Riskiest/most uncertain scopes first (push uphill)
2. Get them over the hill (validate with working code)
3. Leave downhill and move to next risky scope
4. Routine/low-risk scopes last

**For each scope:**
```
A. Write tests for the scope's must-haves
B. Implement (backend → frontend, vertical integration)
C. Tests pass
D. Browser verification (web projects)
E. Update hill chart position
F. Commit changes with meaningful message
G. Mark scope tasks as done in scope file
H. Update TodoWrite
```

**Continuous scope hammering** — for every new task that surfaces:
- Is it a must-have? If not → mark with `~`
- Could we ship without it? If yes → `~`
- Is this a new problem or pre-existing? If pre-existing → `~`
- Edge case or core? If edge → `~`

### Step 5: Resume from Handover (Continuation Sessions)

If this is NOT the first session:

1. Read the latest `handover-NN.md` from the feature folder
2. Read `hillchart.md` for current state
3. Read scope files for task status
4. Pick up where the last session left off:
   - Check which scopes are done, uphill, or downhill
   - Identify the next scope to tackle (riskiest remaining)
   - Continue the TDD loop from Step 4

### Step 6: Capacity Check and Scope Hammering

**Monitor your session capacity.** When you sense the session is getting long and significant
work remains, trigger an interactive scope hammering session:

1. **Assess remaining work**:
   - How many scopes are still uphill?
   - How many must-have tasks remain?
   - Is there anything stuck?

2. **If capacity is tight**, use AskUserQuestion:
   - Present the remaining scopes and their hill positions
   - For each scope with remaining work, ask:
     - "This scope has N must-haves left. Should we: keep as must-have / mark as nice-to-have / cut entirely?"
   - For any scope still uphill:
     - "This scope still has unknowns. Should we: push through / simplify / defer to next session / cut?"

3. **Apply decisions**: Update scope files and hillchart.md

4. **If work remains after hammering** → proceed to Step 7 (Handover)
5. **If all must-haves are done** → proceed to Step 8 (Ready to Ship)

### Step 7: Write Handover

When the session must end with work remaining:

1. **Determine handover number**:
   ```bash
   NEXT=$(ls <feature-dir>/handover-*.md 2>/dev/null | wc -l)
   NEXT=$((NEXT + 1))
   PADDED=$(printf "%02d" "$NEXT")
   ```

2. **Write handover document** to `<feature-dir>/handover-<NN>.md`:
   ```markdown
   # Handover — Session <NN>

   **Date**: <date>
   **Feature**: <NNN> — <name>

   ## Completed This Session
   - <Scope>: <what was done>
   - <Scope>: <what was done>

   ## Current Hill Chart
   <copy latest hillchart state>

   ## Next Session Should
   1. <Most important next scope to tackle>
   2. <Second priority>
   3. <Third priority>

   ## Known Unknowns
   - <Anything stuck uphill that needs investigation>
   - <Blockers or dependencies>

   ## Scope Hammering Decisions Made
   - <What was cut or marked nice-to-have and why>

   ## Code Changes
   - <Files modified>
   - <Commits made>
   - <Tests added/modified>
   ```

3. **Update hillchart.md** with final positions
4. **Commit all changes** (code + shapeup docs)
5. Tell user: "Run `/build <NNN>` in a new session to continue"

### Step 8: Ready to Ship

When all must-haves are complete and all scopes are downhill or done:

1. **Final verification**:
   - Run full test suite
   - Browser verification of complete flow (web projects)
   - Compare to baseline: Is this better than what existed before?

2. **Update hill chart** — all scopes should show ✓ or ▼ near done

3. **Write build summary** for the ship phase.
   This is the builder's raw notes — ship uses it as *input* (alongside `frame.md` and `package.md`)
   to produce the formal `decisions.md`. Keep it factual; ship handles the analysis.
   Write `<feature-dir>/build-summary.md`:
   ```markdown
   # Build Summary — <Feature Name>

   **Feature ID**: <NNN>
   **Build sessions**: <how many>
   **Date completed**: <date>

   ## What Was Built
   - <Bullet list of implemented functionality>

   ## What Was Cut (Scope Hammering)
   - <Item>: <Why acceptable to cut>

   ## Files Changed
   - <List key files added or modified>

   ## What Surprised Us
   - <Anything harder/easier than expected, lessons learned>
   ```

4. **Ask user** via AskUserQuestion:
   - "All must-haves are complete. Ready to ship?"
   - Options: "Ship it" / "One more pass" / "Need to scope hammer more"

5. If shipping: Tell user to run `/ship <NNN>` to archive and produce ADRs

## Hill Chart Format

```markdown
# Hill Chart — <Feature Name>
**Updated**: <date>
**Session**: <NN>

## Scopes
  ✓ <Scope Name> — Done (deployed, tests passing)
  ▼ <Scope Name> — Downhill (executing known work, near done)
  ▼ <Scope Name> — Downhill (executing, significant work remains)
  ▲ <Scope Name> — Uphill (approach validated, some unknowns)
  ▲ <Scope Name> — Uphill (investigating, major unknowns)
  ~ <Scope Name> — Nice-to-have (cut if needed)

## Risk
<The riskiest scope and what's unknown about it>

## Next
<What should be pushed uphill next>
```

---

## Anti-Patterns to Avoid

- **All design then all code**: Horizontal layers fail. Integrate vertically: one piece at a time, UI + backend.
- **Starting with peripheral features**: Login, setup, infrastructure. Start with the CORE.
- **Pre-planning all tasks**: Imagined tasks ≠ discovered tasks. Let real work reveal what's needed.
- **Estimating task duration**: Use hill position (uphill/downhill), not hours.
- **Skipping tests**: TDD is not optional. Tests define "done" and prevent regressions.
- **Pushing through when uphill at session end**: That's a shaping failure. Hand over, don't heroics.
- **Organizing by role**: Not "designer tasks" and "programmer tasks". Organize by scope.
- **Mixing reactive work**: Bugs and incidents are separate. Don't let them eat the build sessions.
