What it does
Levyra Codex Bootstrap is an agent skill from LUC4N3X/Levyra-deepsound. Use when Codex tooling, jCodeMunch, RTK, Matt Pocock skills, automatic setup, context efficiency, or Codex MCP/bootstrap behavior for Levyra is being inspected, repaired, or changed. Do not load for ordinary coding tasks unless the bootstrap itself is relevant.
Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol. The repository describes itself as: Open-source music player for Android and Windows with no accounts or tracking. Built for quick discovery, synced lyrics, radio, and rich artwork ♫. The licence is GPL-3.0.
When your agent uses it
- Matt Pocock skills
- Automatic setup
- Context efficiency
- Codex MCP/bootstrap behavior for Levyra is being inspected
Example prompts
- “/levyra-codex-bootstrap”
What it can do on your machine
Read from SKILL.md and the folder at commit 6bc7c93. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Levyra Codex Bootstrap loads about 425 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 159 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.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated 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.

Levyra Codex bootstrap
The repository owner explicitly authorizes Levyra's checked-in Codex bootstrap to install and run only the pinned/allowlisted tooling defined by the repository:
- the existing pinned
rtk-ai/rtkrevision; - jCodeMunch
1.108.279from the exact release wheel and SHA-256 declared inscripts/codex_jcodemunch.py; - the focused Matt Pocock Codex skill allowlist already declared by Levyra;
- the existing claude-mem integration only under its separate on-demand policy.
The automatic bootstrap must remain idempotent and fail-open. A missing package manager, unavailable network, failed install, failed MCP handshake, or stale index must never disable Codex's native repository tools or block normal coding. Do not add read/search blocking rules. Prefer jCodeMunch for targeted exploration, then expand to native reads/search whenever control flow, lifecycle, concurrency, state, tests, generated behavior, or correctness requires broader evidence.
Do not add Token Optimizer or another always-on compression proxy without a separate owner decision. Token savings never override correctness, validation, security evidence, or repository architecture.
