dotfiles AGENTS.md

dotfiles AGENTS.md is an instructions file for Codex, OpenCode from M0rtalPhe0nix/dotfiles. It costs 451 tokens per session, scanned C, original, MIT.

Repository instructions for coding agents working on the M0rtalPhe0nix/dotfiles project. They require using rtk, a command wrapper that shortens common command output, when running shell commands.

In plain words
What is it for?
Use them when inspecting or changing this repository, running tests and checks, or viewing GitHub and Git information.
Why use it?
They give the agent consistent rules for reading files, testing, building, linting, searching, and working with Git while reducing unnecessary output.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 C, and why

dotfiles AGENTS.md scanned grade C 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.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Agent Instructions

RTK (Rust Token Killer) - Token-Optimized Commands

When running shell commands, always prefix with rtk. This reduces context usage by 60-90% with zero behavior change. If rtk has no filter for a command, it passes through unchanged — so it is always safe to use.

Key Commands

# Git (59-80% savings)
rtk git status          rtk git diff            rtk git log

# Files & Search (60-75% savings)
rtk ls <path>           rtk read <file>         rtk grep <pattern>
rtk find <pattern>      rtk diff <file>

# Test (90-99% savings) — shows failures only
rtk pytest tests/       rtk cargo test          rtk test <cmd>

# Build & Lint (80-90% savings) — shows errors only
rtk tsc                 rtk lint                rtk cargo build
rtk prettier --check    rtk mypy                rtk ruff check

# Analysis (70-90% savings)
rtk err <cmd>           rtk log <file>          rtk json <file>
rtk summary <cmd>       rtk deps                rtk env

# GitHub (26-87% savings)
rtk gh pr view <n>      rtk gh run list         rtk gh issue list

# Infrastructure (85% savings)
rtk docker ps           rtk kubectl get         rtk docker logs <c>

# Package managers (70-90% savings)
rtk pip list            rtk pnpm install        rtk npm run <script>

Rules

  • In command chains, prefix each segment: rtk git add . && rtk git commit -m "msg"
  • For debugging, use raw command without rtk prefix
  • rtk proxy <cmd> runs command without filtering but tracks usage

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.
