session-startRuns the session startup procedure - verifies setup, loads config and state, checks skill models, and reports project status.
Session Start is an agent skill from bitwize-music-studio/claude-ai-music-skills. Runs the session startup procedure - verifies setup, loads config and state, checks skill models, and reports project status. Use at the beginning of a fresh session.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: Human + AI music production workflow for Suno - skills, templates, and tools. The licence is CC0-1.0.
10 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 58f32c2. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:

Shell commands in SKILL.md call:
python3pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Session Start loads about 2k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 825 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Bash, Glob, Grep, WebSearch, WebFetch, bitwize-music-mcpAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

rebuild_state()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.
pending is empty (reason: "current", or reason: "unknown" when the
installed version can't be read from plugin.json): No action needed.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 executinginfo: Display to the usermanual: Show the instruction to the useracknowledge_migrations (no argument
acknowledges everything up to the installed version) so the same notes do
not surface again next session.
reason: "untracked"means the state predates migration tracking; the full backlog up to the installed version is surfaced once, then cleared byacknowledge_migrations. Do NOT just rebuild state to clear migrations — a rebuild preserves the pending status; onlyacknowledge_migrationsrecords that you processed them.
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.
Using data from state.json, report:
From state.ideas.counts — show count by status (Pending, In Progress, etc.)
Filter state.albums for status: "In Progress", "Research Complete", "Complete"
For each, show:
From state.albums — find tracks where sources_verified is "Pending"
If any found, warn: "These tracks have unverified sources — generation is blocked until verified."
From state.session:
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):
/bitwize-music:resume to quickly jump back into an album"/bitwize-music:clipboard to copy lyrics/prompts for Suno"/bitwize-music:mastering-engineer for professional results"End with: "What would you like to work on?"

Runs the session startup procedure - verifies setup, loads config and state, checks skill models, and reports project status. Session Start is an agent skill from bitwize-music-studio/claude-ai-music-skills. Runs the session startup procedure - verifies setup, loads config and state, checks skill models, and reports project status.
Session Start fits situations like: agent Workflows work in your project.
Run `npx skills add bitwize-music-studio/claude-ai-music-skills --skill session-start -a claude-code`. Or copy the skill folder (skills/session-start in bitwize-music-studio/claude-ai-music-skills) into .claude/skills/session-start in your project. Claude Code loads it when a task matches its description.
Run `npx skills add bitwize-music-studio/claude-ai-music-skills --skill session-start -a codex`. Or copy the skill folder (skills/session-start in bitwize-music-studio/claude-ai-music-skills) into .agents/skills/session-start in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bitwize-music-studio/claude-ai-music-skills --skill session-start -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/session-start, .gemini/skills/session-start, .github/skills/session-start and .opencode/skills/session-start in your project.
Going by SKILL.md and its folder, Session Start needs the command-line tools its instructions call (python3 and python). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Bash, Glob, Grep, WebSearch, WebFetch, bitwize-music-mcp.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Session Start is published under the CC0-1.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2k tokens (SKILL.md is roughly 7.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
