You are working on CFX Developer Tools, a Cursor IDE plugin for FiveM and RedM resource development.

## Repo structure

- `.cursor-plugin/plugin.json` -- plugin manifest (version is auto-managed by CI)
- `skills/` -- 9 SKILL.md files (resource scaffolding, natives, fxmanifest, client-server, framework detection, performance, NUI, database, state bags)
- `rules/` -- 6 .mdc rule files (Lua, JS, C# conventions, fxmanifest standards, security, performance)
- `snippets/` -- 24 code snippets organized by language (lua, javascript, csharp)
- `templates/` -- 11 resource templates (standalone, esx, qbcore, qbox, oxcore, vorp, rsg, javascript, csharp, nui-vite, nui-svelte)
- `mcp-server/` -- Python FastAPI MCP server with 6 tools and JSON data files
- `docs/` -- architecture, roadmap, contributing, getting started
- `.github/workflows/` -- validate, release, update-natives, update-docs-index, stale, deploy-docs
- `mkdocs.yml` -- MkDocs Material config; docs site auto-deploys on push to main
- `AGENTS.md` -- full workflow and contribution guide for AI agents
- `CHANGELOG.md` -- manually maintained release history

## Commit conventions

Use conventional commits. The release workflow auto-bumps version based on prefix:
- `feat:` = minor bump
- `feat!:` or `BREAKING CHANGE` = major bump
- `fix:`, `chore:`, `docs:`, `refactor:`, etc. = patch bump

## Version management

Never manually edit the version in `plugin.json` or the README version badge. The release workflow (`release.yml`) auto-updates both on push to main.

## Hard rules

- No em dashes or en dashes anywhere. Use hyphens or rewrite.
- No `lua54 'yes'` in any template or generated manifest. Lua 5.4 is the only runtime; the directive is deprecated.
- No hardcoded credentials, tokens, API keys, or passwords.
- All fxmanifest.lua must use `fx_version 'cerulean'` and include `games`.
- Python in `mcp-server/` must pass `py_compile`.
- Server-side event handlers must validate `source`.
- C# resources use a single compiled DLL referenced in both `client_scripts` and `server_scripts`.

## When editing skills or rules

- Skills are SKILL.md with YAML frontmatter. Keep them accurate to current FiveM/RedM APIs.
- Rules are .mdc with frontmatter (`description`, `globs`, `alwaysApply`). They enforce conventions in generated code.
- After adding/removing a skill or rule, update `plugin.json` to register it and update counts in README.md.
- CI validates that README counts match actual file counts on disk.

## When editing the MCP server

- Shared manifest logic lives in `mcp-server/tools/manifest_common.py`. Don't duplicate it.
- Don't manually edit `mcp-server/data/natives_*.json`. The update-natives workflow manages these.
- Dependencies are pinned in `mcp-server/requirements.txt`.

## When editing templates

- Every template directory needs at minimum a `fxmanifest.lua`.
- Never include `lua54 'yes'`.
- Follow the existing pattern: fxmanifest.lua + client.lua/js + server.lua/js (or .csproj + .cs).

## When editing workflows

- `release.yml` uses `[skip ci]` on its version bump commit. Don't remove that.
- `release.yml` paths-ignore excludes `.github/**`, `docs/**`, `*.md`, `LICENSE`. Content-only changes won't trigger releases.
- `release.yml` has a concurrency guard. Only one release can run at a time.
- `release.yml` auto-syncs the GitHub repo About section (description, homepage, topics) after every release. Do not manually edit the About section.
- `deploy-docs.yml` builds the MkDocs Material site and deploys to GitHub Pages on every push to main.
- `update-natives.yml` commits with `chore:` prefix (patch bump). Don't change to `feat:`.
- `validate.yml` runs on both PR and push. Keep checks fast.
- `CHANGELOG.md` is manually maintained. Update it for significant changes.

## Native databases

Data sourced from `runtime.fivem.net/doc/` (GTA5, RDR3, CFX). ~6000+ GTA5, ~5800+ RDR3 natives.

The flat JSON schema for natives:
```json
{ "name": "string", "hash": "0x...", "params": [{"type":"","name":""}], "return_type": "string", "description": "string", "category": "string", "side": "client|server|shared", "deprecated": false, "examples": "string|null" }
```

The `lookup_native_tool` supports: keyword search, hash lookup, category/namespace browsing (empty query + category), listing all categories (empty query + no category), and side filtering.

Events use: `{ "name", "side", "description", "params", "game", "framework" }`. 101 events across cfx, baseevents, chat, esx, qbcore, qbox, oxcore, vorp, rsg.

Docs index: `mcp-server/data/docs_index.json` -- ~80 pages from docs.fivem.net, rebuilt monthly by CI. Schema: `{ "title", "url", "section", "snippet" }`.

Framework detection: `detect_framework_tool` scans fxmanifest.lua deps and code patterns. Returns framework name, confidence, and evidence. Supports ESX, QBCore, Qbox, ox_core, VORP, RSG, and standalone.
