## Your Task

Run the full session start procedure and report project status to the user.

---

# Session Start Skill

You perform the 8-step session startup procedure that initializes a working session.

---

## Step 1: Verify Setup

Quick dependency check:

```bash

~/.bitwize-music/venv/bin/python3 -c "import mcp" 2>&1 >/dev/null && echo "MCP ready" || echo "MCP missing"

```

- If MCP missing: **Stop immediately** and suggest: `/bitwize-music:setup mcp`

- If config missing (`~/.bitwize-music/config.yaml` doesn't exist): suggest `/bitwize-music:configure`

- Don't proceed until setup is complete

## Step 1.5: Health Check

**Venv results** (from `result.venv`):

- `status: "ok"` → continue silently

- `status: "stale"` → warn with mismatches and fix command, continue session

- `status: "no_venv"` → **stop** and suggest `/bitwize-music:setup`

- `status: "error"` → warn and continue

**Skill registration results** (from `result.skills`):

- `status: "ok"` → continue silently

- `status: "stale"` → warn: list missing and ghost skill names, show fix message

- `status: "no_cache"` → warn that plugin cache not found, continue

## Step 2: Load Config

Read `~/.bitwize-music/config.yaml`.

If missing, tell user to run `/bitwize-music:configure`.

## Step 3: Load Overrides

Read `paths.overrides` from config (default: `{content_root}/overrides`):

- Check for `{overrides}/CLAUDE.md` — incorporate instructions if found

- Check for `{overrides}/pronunciation-guide.md` — note if found

- Skip silently if missing (overrides are optional)

## Step 4: Load State Cache

Read `~/.bitwize-music/cache/state.json`:

- If missing, corrupted, schema mismatch, or config changed: rebuild via MCP

```

rebuild_state()

```

## Step 4.5: Check for Plugin Upgrades

Call the `get_pending_migrations` MCP tool. It compares the installed plugin

version against `last_migrated_version` in state (the last version whose

migrations were processed — distinct from `plugin_version`, which only records

the installed version for display) and returns the pending notes already

parsed and sorted.

1. **If `pending` is empty** (`reason: "current"`, or `reason: "unknown"` when the

installed version can't be read from plugin.json): No action needed.

2. **If `pending` is non-empty** (`reason: "upgrade"` or `"untracked"`): For each

migration, process its `actions` in order:

- `auto`: Execute silently (run `check` first — skip if it returns 0)

- `action`: Show description, ask the user to confirm before executing

- `info`: Display to the user

- `manual`: Show the instruction to the user

3. **After processing all notes**, call `acknowledge_migrations` (no argument

acknowledges everything up to the installed version) so the same notes do

not surface again next session.

4. Report: "Upgraded to Y" with a summary of the actions taken.

> `reason: "untracked"` means the state predates migration tracking; the full

> backlog up to the installed version is surfaced once, then cleared by

> `acknowledge_migrations`. Do NOT just rebuild state to clear migrations —

> a rebuild preserves the pending status; only `acknowledge_migrations` records

> that you processed them.

## Step 5: (Removed)

Skill model checking is no longer part of session start. Skills use tier aliases (`opus`/`sonnet`/`haiku`) that auto-track the frontier model, and the test suite (`/bitwize-music:test`) enforces model/effort hygiene — so no manual model checking is needed when new Claude models are released.

## Step 6: Report From State Cache

Using data from `state.json`, report:

### Album Ideas

From `state.ideas.counts` — show count by status (Pending, In Progress, etc.)

### In-Progress Albums

Filter `state.albums` for status: "In Progress", "Research Complete", "Complete"

For each, show:

- Album name, genre, status

- Track progress (completed/total)

### Pending Source Verifications

From `state.albums` — find tracks where `sources_verified` is "Pending"

If any found, warn: "These tracks have unverified sources — generation is blocked until verified."

### Last Session Context

From `state.session`:

- Last album worked on

- Last phase

- Pending actions

## Step 7: Show Contextual Tips

Based on state, show ONE relevant tip:

| Condition | Tip |

|-----------|-----|

| No albums exist | "Try `/bitwize-music:tutorial` to create your first album" |

| Ideas exist but no albums | "You have album ideas! Use `/bitwize-music:album-ideas list` to review them" |

| In-progress albums exist | "Resume where you left off: `/bitwize-music:resume <album-name>`" |

| Overrides loaded | "Custom overrides loaded from {overrides}/" |

| Overrides missing | "Customize your workflow with override files — see `/reference/overrides/`" |

| Pending verifications | "Source verification needed before generation can proceed" |

Also show one random general tip (rotate through these):

- "Ask 'what should I do next?' for workflow guidance"

- "Use `/bitwize-music:resume` to quickly jump back into an album"

- "The researcher skill coordinates 10 specialized sub-skills for deep research"

- "Check pronunciation before generating — Suno can't infer from context"

- "Use `/bitwize-music:clipboard` to copy lyrics/prompts for Suno"

- "Master your audio with `/bitwize-music:mastering-engineer` for professional results"

## Step 8: Ask

End with: "What would you like to work on?"

## Remember

1. **Don't skip steps** — Each step matters for session integrity

2. **Rebuild state if needed** — Stale state leads to wrong recommendations

3. **Be concise** — This is a status report, not a conversation

4. **Warn about verifications** — Unverified sources block generation

5. **One tip, not five** — Pick the most relevant tip for the current state
