## What it does

The skill packages project triggers and classes into a zip archive, submits them to the ApexGuru SFAP Scan API, and polls for results. Once finished, it decodes the base64 report and prints structured violation cards with file locations, severity levels, and concrete remediation steps. It catches SOQL or DML statements inside loops, `Schema.getGlobalDescribe()` calls, and SOQL queries lacking `WHERE` or `LIMIT` clauses.

All operations rely on bundled shell scripts wrapped by `scan.sh`. The decoding step formats markdown cards alongside an attribution banner: "Static only" for source scans, or "Production insights" when org runtime data is active. If you need to filter results by file or rule, you can rerun the decoder against the saved raw JSON without triggering another API call.

Your environment must include `sf >=2.0.0`, `node >=18.0.0`, `jq >=1.6.0`, and `curl >=7.0.0`. The skill is dedicated exclusively to Apex performance antipatterns and will not handle security scans or generic static code analysis.

## Requirements
- Works with: Salesforce

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill dx-apexguru-scan -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill dx-apexguru-scan -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill dx-apexguru-scan -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install forcedotcom/sf-skills dx-apexguru-scan
```

2. **Manually: put the files in place**
- File: `.github/skills/dx-apexguru-scan/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill dx-apexguru-scan -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/forcedotcom/sf-skills --path skills/dx-apexguru-scan
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill dx-apexguru-scan -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/skills/dx-apexguru-scan/SKILL.md

## When to use it
- detect SOQL and DML operations inside loops
- locate costly `Schema.getGlobalDescribe()` calls
- identify SOQL queries missing `WHERE` or `LIMIT` clauses
- flag queried SOQL fields that remain unused

## Example prompts
- Run an ApexGuru scan on this project
- Check Apex performance and find SOQL in loop issues
- Scan my Apex code for governor-limit antipatterns

description: "Run an ApexGuru performance scan on a Salesforce Apex project via the ApexGuru SFAP Scan API. Zips the project's Apex (any layout), submits it, polls to completion, decodes the base64 report, and presents performance antipattern violations (SOQL in loop, DML in loop, Schema.getGlobalDescribe(), SOQL without WHERE/LIMIT, unused SOQL fields) grouped by rule with severity, file:line, and suggested fixes — clearly attributed as 'Static only' or 'Production insights'. TRIGGER when the user says 'run ApexGuru', 'ApexGuru scan', 'check Apex performance', 'find governor-limit / performance antipatterns', 'SOQL in loop', 'scan my Apex for performance', or 'ApexGuru performance insights'. DO NOT TRIGGER for general static analysis or security scans (use dx-code-analyzer-run), for fixing code without scanning, or for onboarding an org to ApexGuru."

# ApexGuru Performance Scan Skill

## CRITICAL: Mandatory Script Usage

Every step — token resolution, zipping, API calls, and report decoding — MUST go
through the bundled scripts in `<skill_dir>/scripts/`. No exceptions.

### WRONG — never do this:

```bash
# WRONG: hand-rolled curl to the API
curl -X POST https://api.salesforce.com/... -F file=@x.zip

# WRONG: inline base64 + jq to read the report
cat raw.json | jq -r .report | base64 -d | jq '.[]'

# WRONG: reading the raw result file directly (report is a large base64 blob)
Read tool → apexguru-raw-*.json

# WRONG: inline node/python to parse violations
node -e "const r = require('./raw.json'); ..."
```

### RIGHT — always do this:

```bash
# PREFERRED — one command runs all three steps (package → submit+poll →
# decode+present) and prints the ready-to-show report as its final stdout.
# Use this for every initial scan: it cannot be left half-finished.
bash "<skill_dir>/scripts/scan.sh" "<project-root>"

# Optionally persist the presented markdown to a file as well:
bash "<skill_dir>/scripts/scan.sh" "<project-root>" --out ./apexguru-report.md
```

The three underlying scripts still exist and `scan.sh` calls them in order.
Invoke them individually only for **drill-downs on an already-scanned result**
(Step 5), or when you deliberately need to inspect an intermediate artifact:

```bash
````

The third-party file has ended. Everything between the fde8a39a00ca1bc0 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
