my-ai-tools: Instructions file for Codex

AGENTS.md

my-ai-tools AGENTS.md is an instructions file for Codex, OpenCode from jellydn/my-ai-tools. It costs 1,809 tokens per session, scanned A, original, MIT.

Agent instructions for my-ai-tools, a monorepo containing shared configuration for more than a dozen AI coding assistants. It installs and exports each tool’s configuration through shell scripts.

In plain words
What is it for?
Use them when changing tool configurations, installation or export scripts, command-line flags, formatting rules, or automated checks.
Why use it?
They make installation and export safer by requiring dry-run previews and checks for syntax, formatting, tests, and profile synchronisation.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is jellydn/my-ai-tools's own configuration. It tells Codex and OpenCode how to work on my-ai-tools 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 my-ai-tools 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

my-ai-tools 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 4d 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.

Agent Instructions

What This Is

Monorepo for my-ai-tools — source-of-truth configs for 14+ AI coding assistants (Claude Code, OpenCode, Amp, Codex, Gemini, Antigravity, Cursor, Cline, Grok, etc.). It installs configs to ~/.claude/, ~/.config/opencode/, ~/.pi/, etc. and exports them back via generate.sh. Per-tool configs live in configs/<tool>/.

Essential Commands

bash -n cli.sh generate.sh lib/*.sh lib/install.sh  # Syntax gate (CI runs this)
bash -n cli.sh generate.sh install.sh scripts/*.sh   # CI gates this exact set
./cli.sh --dry-run                                    # Preview install plan — ALWAYS run first
./cli.sh                                              # Install configs into $HOME
./generate.sh --dry-run                               # Preview export
./generate.sh                                         # Export local configs from $HOME back to repo
./scripts/sync-token-efficiency.sh --check            # Verify profiles are in sync (exit 1 if stale)
biome check .                                         # Format check (tabs, 120 width, double quotes)
biome check --write .                                 # Format in place
bats tests/                                           # Run ALL functional tests locally
bats tests/cli.bats                                   # Run a single test file

Workflow

./cli.sh --dry-run  →  git diff  →  ./cli.sh  →  git diff  →  commit

Never run ./cli.sh without --dry-run first. Config validation runs automatically and warns on failures.

cli.sh Flags

  • --dry-run — side-effect-free preview
  • --backup / --no-backup — backup existing configs (auto-prompted interactively)
  • -y / --yes — non-interactive; installs Amp, Pi, Codex, OpenCode, Claude, Grok, qmd, rtk, ctx, open-cursor, ai-switcher, open_code_review, and Plannotator, plus shared skills, applicable MCP/plugin config, and declared integration dependencies. ctx installs without history import. Auto-activated in CI/piped input. Other standalone catalog entries remain optional; user-memory stays opt-in.
  • --with-tools=name,... — opt into extra catalog CLIs such as fx or cursor.
  • --with-integrations — bundled config, plugins, skills, MCPs, and their prerequisites (default); can replace existing config.
  • --without-integrations — standalone CLIs only; leaves existing config unchanged.
  • --migrate-gemini — one-step Gemini→Antigravity CLI migration
  • --rollback — restore from the most recent $HOME/ai-tools-backup-{timestamp}
  • -v / --verbose — verbose logging
  • -h / --help — print usage options and exit

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.
