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:

~/.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

Use the health_check MCP tool (checks venv packages + skill registration in one call):

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

Compare plugin_version in state.json against current version in ${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json:

If plugin_version is null (first run or pre-upgrade-system): Set to current version, skip migrations
If versions match: No action needed
If stored < current (upgrade detected):
- Read migration files from ${CLAUDE_PLUGIN_ROOT}/migrations/ for versions between stored and current
- Process actions in order:
  - auto: Execute silently (run check first — skip if returns 0)
  - action: Show description, ask user to confirm before executing
  - info: Display to user
  - manual: Show instruction to user
- Rebuild state to update plugin_version
Report: "Upgraded from X to Y" with summary of actions taken

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?"

Report Format

SESSION START
=============

Setup: MCP ready, config loaded
Health: [venv ok, skills ok | warnings listed]
Overrides: [loaded from {path} | not found (optional)]
State: [loaded | rebuilt | error]

ALBUM IDEAS
  Pending: X | In Progress: Y

IN-PROGRESS ALBUMS
  [album-name] (genre) - Status [X/Y tracks]
  [album-name] (genre) - Status [X/Y tracks]

PENDING VERIFICATIONS
  [album-name]: track-01, track-05

LAST SESSION
  Album: [name] | Phase: [phase]
  Pending: [actions]

TIP: [contextual tip]

What would you like to work on?

Remember

Don't skip steps — Each step matters for session integrity
Rebuild state if needed — Stale state leads to wrong recommendations
Be concise — This is a status report, not a conversation
Warn about verifications — Unverified sources block generation
One tip, not five — Pick the most relevant tip for the current state
