subwave-worktree-dev

A setup helper for running the SUB/WAVE development stack from a Git worktree, a second checkout linked to the same repository. It supplies ignored configuration and state files that Git worktrees do not copy, then starts the stack.

In plain words
What is it for?
Use it to prepare a worktree with the required environment files, Node packages, credentials, and state directory, then launch SUB/WAVE for testing.
Why use it?
It prevents missing environment files, dependencies, or saved setup data from breaking a development checkout.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

subwave-worktree-dev scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/prep-worktree.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SUB/WAVE worktree dev setup

Get the SUB/WAVE dev stack running from inside a git worktree so branch changes can be tested without touching the main checkout.

Why a worktree needs prep

A worktree checks out every tracked file, so all source is already there. But the dev stack also depends on gitignored files that do not travel with a worktree checkout:

File Why the stack needs it
.env Root .envADMIN_USER / ADMIN_PASS / SITE_URL. Dev compose references it as ./.env; compose refuses to start without it.
controller/.env Dev compose declares env_file: ./controller/.env — controller container won't start without it. Navidrome + Ollama config.
web/.env.local Dev API/stream URL overrides (NEXT_PUBLIC_API_URL etc.). Without it the web UI defaults to same-origin /api and cannot reach the controller.
docker/.env Compose variable substitution (legacy — harmless to copy).
state/setup-config.json Navidrome creds the wizard saved on main. Without this the controller reports needsSetup: true and the player redirects to /onboarding on every load.
state/secrets.env Cloud LLM / TTS API keys (if main has any). Sourced into the controller's process.env on boot.
state/settings.json Operator's full config — LLM provider/model, personas, shows, TTS. Without it the controller boots with default settings (llm.model = ''), every LLM call returns "fetch failed", and the new skills cannot run.
state/moods.json Library mood tagging produced by npm run tag (LLM walk over the whole library — expensive to redo per branch).
state/sfx.json + sfx/ Sound-effects catalogue metadata + rendered WAVs the admin UI lists and liquidsoap mixes in.
state/jingles.json + jingles.m3u + jingles/ Pre-rendered station idents. Liquidsoap reads the M3U with reload_mode="watch".
state/recent-plays.json 24h play log — the picker and the library-deep-cut skill key off it for dedup.
state/sessions/ Archived DJ sessions (the live one is regenerated on boot).
state/voice/ Persona TTS reference voices (Chatterbox cloning refs, if any).
web/node_modules Needed by npm run dev.
state/ Bind-mounted into the containers. A worktree's state/ is empty.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

subwave-worktree-dev is a skill published in the GitHub repository perminder-klair/subwave (1,287 stars, last pushed 3d ago), licensed MIT. It adds 196 tokens to every session and 2,186 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
