What it does

Levyra Engineering is an agent skill from LUC4N3X/Levyra-deepsound. Coordinate cross-domain Levyra work that spans multiple subsystems, or orient an agent when no single specialized Levyra skill is sufficient. Prefer a specialized levyra- skill for focused tasks.

Its SKILL.md is about 880 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 Security. It works with Android. 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.

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Read the root AGENTS.md completely.
Read every nearest AGENTS.md covering the files in scope.
Read docs/ARCHITECTURE.md and current implementation/tests.
Select every specialized skill that applies.
Establish one coherent change contract before editing.

What it can do on your machine

Read from SKILL.md and the folder at commit 35cd2be. 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 Engineering loads about 876 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~54
When it runs · the whole SKILL.md, loaded when a task matches: ~876

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.

Cross-domain change contract

Before editing, state internally:

the exact user or developer outcome;
the current control and data flow across modules;
behavior and compatibility that must remain unchanged;
ownership boundaries between UI, state, repositories, players, services, databases, native resources, workflows, and releases;
the smallest coherent set of files;
focused tests and broader validation required;
checks that depend on Android SDK, JDK, Windows, libvlc, signing inputs, network, CI, emulator, or device.

Coordination rules

Current repository content is authoritative; do not rely on remembered versions.
Prefer one source of truth and existing infrastructure over adapters that duplicate state or behavior.
Keep Android and Desktop versioning and release behavior independent.
Make security, persistence, lifecycle, and cancellation behavior explicit at subsystem boundaries.
Avoid broad refactors unless the requested result cannot be achieved safely within current architecture.
Run focused validation per subsystem, then inspect the complete integrated diff.

Delivery

Report rationale/root cause, files changed, subsystem interactions, behavior preserved, tests/checks with results, blocked checks, residual risk, manual validation, and publication state. Never represent a plan as an applied patch or a skipped check as a pass.
