Supported AI tools

Tool	Entry file	Install path
Claude Code	SKILL.md (with dispatch frontmatter)	~/.claude/skills/hapex3-lua/
OpenAI Codex CLI	AGENTS.md	~/.codex/hapex3-lua/ + reference appended to ~/.codex/AGENTS.md
opencode TUI	AGENTS.md	~/.config/opencode/hapex3-lua/ + reference appended to ~/.config/opencode/AGENTS.md
Aider / other AGENTS.md tools	AGENTS.md	Manual placement

The pack ships both SKILL.md (Claude Code dispatch entry) and AGENTS.md (universal multi-tool entry). The two are content-equivalent; the references/ directory is shared.

Install

One-click script

Platform	Install to all tools	Install to one
Windows	.\install.ps1	.\install.ps1 -Target claude
macOS / Linux	./install.sh	./install.sh --target=claude

-Target / --target= accepts claude / codex / opencode / all (default).

The installer detects and overwrites any prior version. For Codex / opencode it also appends one reference line to the corresponding AGENTS.md (with marker # === hapex3-lua pack (auto-managed) === so reinstalling never duplicates).

Manual install

Copy the hapex3-lua/ directory to the target tool's location:

Tool	Target directory
Claude Code	~/.claude/skills/hapex3-lua/ (Windows: %USERPROFILE%\.claude\skills\hapex3-lua\)
Codex CLI	~/.codex/hapex3-lua/ (Windows: %USERPROFILE%\.codex\hapex3-lua\)
opencode	~/.config/opencode/hapex3-lua/

For Codex / opencode, also append one line to the tool's AGENTS.md:

See `<install-path>/hapex3-lua/AGENTS.md` for HApex3.0 Lua scripting context.

What's in the pack

• Full API reference for all 15 Lua modules (signatures / parameters / returns / behavior)
• Conventions & common pitfalls: colon vs dot, 1-based Combobox, draw.* must be called every frame, no input.is_down(vk) on dual-machine setups, resource auto-cleanup boundaries, gui.set is same-frame visible
• 8 complete example scripts: keybind hints · ESP text · color themes · perf HUD · config presets · loot inspector · WebSocket push · damage logger
• Project structure, load order, cross-script communication, frame_update cadence

Verify the install

After starting the tool, try:

I want to write a HApex3.0 Lua script that draws a red crosshair in the screen center

Expected output should:

• Wrap the drawing in event.on("frame_update", function(e) ... end) (not at script top level)
• Use draw.line with draw.rgba(1, 0, 0, 1)
• Get screen center from draw.screen()

If the output matches that style, the pack is working.

Trigger scenarios

The pack applies when the user mentions:

• Writing / editing / debugging a .lua script (HApex3.0 / HOOZi)
• A specific API: gui.find / esp.add / net.http / draw.text / game.localplayer / event.on, etc.
• "How do I make an ESP / watermark / notification / hotkey hint" type questions
• Porting old scripts to the current API

General HApex3.0 / HOOZi usage questions unrelated to scripting do not trigger this pack.

Upgrades

When a new version is released, re-download the zip and run the installer. The old directory is replaced; the AGENTS.md reference line is never duplicated.

Feedback

Pack content stays in sync with the wiki's English locale. If an API description doesn't match runtime behavior, please report it; the fix lands in the next release.
