Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is lqwdtech/SaturnZap's own configuration. It tells GitHub Copilot how to work on SaturnZap itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything SaturnZap configures →

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

SaturnZap copilot-instructions.md scanned grade A with 0 findings 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 1mo ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SaturnZap — Copilot Instructions

CLI-first, non-custodial Lightning Network wallet for AI agents. Python 3.12, LDK Node, mainnet default.

Build & Test

uv sync                              # Install deps (never pip)
uv run ruff check src/ tests/        # Lint
uv run pytest tests/ -v              # Unit tests (-m "not live" to skip droplet tests)
uv build                             # Build wheel

After code changes, run uv sync to reinstall the package before testing.

Architecture

All source lives in src/saturnzap/. Key modules:

Module Role
cli.py Typer CLI entry point (sz). Each command → JSON output
node.py LDK Node lifecycle. _require_node() lazy-starts; _use_ipc() auto-detects daemon
output.py ok(**fields) → stdout JSON, error(code, msg) → stderr JSON + exit
config.py TOML config + Esplora fallback resolver (3s probe timeout)
keystore.py BIP39 seed + Fernet encryption (PBKDF2, 600K iterations, 16-byte salt)
ipc.py Unix Domain Socket daemon. Newline-delimited JSON, 23 methods, threading.Lock
payments.py BOLT11 invoices, keysend, spending caps, history
l402.py HTTP 402 interceptor, token cache (SHA256-hashed URL)
liquidity.py Channel health scoring (0–100), recommendations
lqwd.py LQWD peer directory — 18 regions + agent-focused AI-Grid (LSPS1/LSPS2 JIT), default on mainnet
mcp_server.py FastMCP stdio server, 25 tools
service.py Systemd service generator

See docs/architecture.md for diagrams and IPC protocol details.

Conventions

  • Output is always JSON: {"status": "ok", ...} or {"status": "error", "code": "...", "message": "..."}. Never print plain text. Use output.ok() / output.error().
  • IPC routing: CLI commands check _use_ipc() first. If daemon is running, route through UDS; otherwise start ephemeral node.
  • Network-namespaced paths: ~/.local/share/saturnzap/<network>/ — each network (signet, bitcoin) has separate seed, socket, config.
  • Passphrase: SZ_PASSPHRASE env var or interactive prompt. No caching.
  • Module-level singletons: _node, _ipc_mode, _active_network, _pretty — use global with # noqa: PLW0603.
  • Mainnet safety: _confirm_mainnet(yes) gate on any command touching bitcoin network.
  • LDK Node v0.7.0: Vendored wheel at vendor/. API: builder.set_entropy_bip39_mnemonic(mnemonic, None), generate_entropy_mnemonic(None).
  • Commit messages: Plain English, no conventional-commit prefixes (feat:, fix:, chore:). Lead with the outcome. Avoid alarm words (fix, bug, warning, error, vulnerability). Examples: Add smart health alerts for payments and balances, Security hardening — payment proofs, graceful shutdown, and integrity checks. Bodies may include technical detail.

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.
