## What it does

This skill documents the MCP tools exposed by the local `salesforce-lsp` server in the `salesforce-development` plugin. It covers compile diagnostics for `.cls` and `.trigger` files through `apex.diagnostics`, plus the meanings of LSP responses and error envelopes.

Use `validate_soql` to parse a query for syntax errors. `complete_soql` resolves schema-aware suggestions against the connected org, while `extract_soql_from_apex` finds inline queries without starting a language server. `lsp.health` reports workspace, server, and circuit-breaker state.

The tooling requires `sf` version `>=2.0.0`, and line and column coordinates start at 1. This build always treats `lwc.*` tools as unavailable because it does not bundle the LWC language server. That means LWC checks need source inspection or deploy compilation instead.

## Requirements
- Works with: Salesforce

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-lsp-integrate -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/platform-lsp-integrate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/platform-lsp-integrate/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-lsp-integrate -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/platform-lsp-integrate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-lsp-integrate -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/platform-lsp-integrate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install forcedotcom/sf-skills platform-lsp-integrate
```

2. **Manually: put the files in place**
- File: `.github/skills/platform-lsp-integrate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-lsp-integrate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/forcedotcom/sf-skills --path plugins/builder/salesforce-development/skills/platform-lsp-integrate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/platform-lsp-integrate/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill platform-lsp-integrate -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/forcedotcom/sf-skills/tree/HEAD/plugins/builder/salesforce-development/skills/platform-lsp-integrate/SKILL.md

## When to use it
- check a `.cls` or `.trigger` file for compile diagnostics
- find syntax errors in a SOQL query
- request schema-aware SObject and field completions
- interpret `lsp_disabled` or `no_apex_workspace` errors
- clear cached schema after deploying a field

## Example prompts
- "Explain why `apex.diagnostics` returned `no_apex_workspace`."
- "Read the `lsp.health` result and explain the Apex LSP state."
- "Which Salesforce LSP tools validate SOQL, and what do they return?"

# Using the Salesforce LSP

The `salesforce-development` plugin hosts a local MCP server named
**`salesforce-lsp`** that lazily spawns Salesforce Language Server children and
exposes their semantic capabilities as MCP tools. This skill is the **contract**
other skills follow when they call those tools, and the answer to "how do I use
the Salesforce LSP?" — what each tool does, how to read its result, what every
error code means, and how to fall back when the host is absent.

This is a documentation/reference skill. It does not author or deploy code; it
tells you (and other skills) how to drive the LSP tools correctly.

> **This plugin build vendors Apex + SOQL only.** The `salesforce-lsp` host
> ships the Apex language server (`@salesforce/apex-ls`) and the SOQL language
> server. The **LWC** language server is intentionally **not** bundled in this
> plugin — the `lwc.*` tools are registered by the host but will always return
> an `unavailable`-class envelope here. Treat any `lwc.*` call as unavailable
> and use the fallback (read the component source / deploy-compile).

## When to Use This Skill

- A user asks how to use the Salesforce LSP, or which LSP/MCP tools are available.
- A user asks what a specific tool does (`apex.diagnostics`, `validate_soql`,
  `complete_soql`, etc.) or how to read its output.
- An LSP tool returned an error envelope (`lsp_disabled`, `spawn_timeout`,
  `circuit_open`, `no_apex_workspace`, `no_org_connected`) and you need to know
  what it means and how to recover.
