lsend-cli: Instructions file for Codex

AGENTS.md

lsend-cli AGENTS.md is an instructions file for Codex, OpenCode from lsendapp/lsend-cli. It costs 1,459 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for lsend, a command-line tool that sends and receives files over the LocalSend device-to-device protocol. They define its non-interactive commands, output formats, flags, logs, and exit codes.

In plain words
What is it for?
Use them when scanning for devices, sending or receiving files, handling JSON or newline-delimited JSON output, troubleshooting errors, or integrating lsend into automation.
Why use it?
They help scripts and coding agents use the tool reliably without waiting for prompts. They also explain how to keep machine-readable output separate from diagnostic messages.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is lsendapp/lsend-cli's own configuration. It tells Codex and OpenCode how to work on lsend-cli 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 lsend-cli configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/me/.config/lsend/alias.txt.

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

lsend-cli AGENTS.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 2mo 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.

lsend CLI — Agent Integration Guide

Machine-readable, non-interactive CLI for the LocalSend protocol.

Progressive docs (offline): lsend agent [alias|scan|send|receive|errors|eval]

Cursor skill: skills/localsend-cli/SKILL.md (install to .cursor/skills/ or use npx skills add if published)

Principles

  • No prompts — all inputs via flags
  • --json — structured stdout only (no human text); also enabled when stdout is piped or LSEND_NO_TUI=1
  • --quiet — minimal stdout in human mode (--json implies quiet)
  • Logs on stderr via -v / RUST_LOG
  • Stable exit codes + code field in error JSON

Global flags

Flag Description
--json JSON stdout (scan/send object, receive NDJSON); auto-enabled when piped
--quiet / -q Suppress progress text (human mode)
LSEND_NO_TUI=1 Same as --json for non-interactive stdout
-v, --verbose Diagnostics on stderr
--http Plain HTTP (default: HTTPS)
--port PORT Default 53317. Keep 53317 for receive — alternate ports break multicast discovery (the LocalSend app and default scan will not see this device).
--alias NAME Override persisted alias for one command only

Exit codes

Code Meaning
0 Success
1 General error (code: "error")
2 Not found / validation (target_not_found, no_files, invalid_alias)
3 Port in use (port_in_use)

scan

lsend scan --json --timeout 5000
{
  "command": "scan",
  "ok": true,
  "timeout_ms": 5000,
  "devices": [{ "alias": "...", "ip": "192.168.1.10", "port": 53317, "https": true, ... }]
}

Empty devices with ok: true is not an error.

alias

Manage the persisted device alias (the LocalSend app UI: Device name). Stored in ~/.config/lsend/alias.txt.

lsend alias show --json
lsend alias regenerate --json
lsend alias regenerate --json --locale zh-CN
lsend alias set "My Laptop" --json

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.
