## What it does

The skill packages your workspace into a zip archive, ignoring build artifacts, caches, and dependency folders like `node_modules`. If the archive exceeds 2 GB, the process aborts immediately. The zip then uploads to an S3 bucket before the agent creates and triggers a `CodeReview` job.

A full scan takes around 45 minutes. The polling loop runs every 5 minutes without spamming updates, reporting back only when the job status changes. Local scan history tracks up to 50 runs in `.security-agent/scans.json`.

AWS credentials and an IAM role are necessary beforehand. If `.security-agent/config.json` is missing, the skill automatically triggers the `setup-security-agent` workflow inline before starting the scan.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill scanning-with-aws-security-agent -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/scanning-with-aws-security-agent/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scanning-with-aws-security-agent/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill scanning-with-aws-security-agent -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scanning-with-aws-security-agent/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill scanning-with-aws-security-agent -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scanning-with-aws-security-agent/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws scanning-with-aws-security-agent
```

2. **Manually: put the files in place**
- File: `.github/skills/scanning-with-aws-security-agent/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill scanning-with-aws-security-agent -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path plugins/aws-agents-for-devsecops/skills/scanning-with-aws-security-agent
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scanning-with-aws-security-agent/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill scanning-with-aws-security-agent -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/aws/agent-toolkit-for-aws/tree/HEAD/plugins/aws-agents-for-devsecops/skills/scanning-with-aws-security-agent/SKILL.md

## When to use it
- scan repository code for security vulnerabilities
- track AWS Security Agent scan progress in the background
- retrieve ranked findings with remediation guidance
- inspect scan history across past runs

## Example prompts
- Run a security scan on this workspace
- What is the status of the current code scan?
- Show recent security scans for this repository

name: scanning-with-aws-security-agent
description: Run an AWS Security Agent scan on the workspace — uploads the source to AWS, scans it with the managed Security Agent service, and returns ranked, verified findings with code locations and remediations. Use when the user asks to scan code, find vulnerabilities, run a security scan or review, check security issues, check scan status, show findings, list recent scans, or stop a scan.

# AWS Security Agent — Code Scans

This skill handles full repository scans. Setup (agent space, role, bucket) is handled by the **`setup-security-agent`** skill — if `.security-agent/config.json` is missing, the scan workflow auto-runs setup inline first.

---

## Action mapping

| User intent | Workflow |
|-------------|----------|
| Direct scan request ("scan my code", "find vulnerabilities") | Full Scan |
| Scan status check ("how's the scan", "progress") | Status workflow |
| View findings ("what did it find", "show results") | Findings workflow |
| List scans ("recent scans", "show my scans") | Read `.security-agent/scans.json` |
| Stop a scan | `aws securityagent stop-code-review-job` |

### Rules for proactive suggestions

- Always ask before running — never auto-trigger scans
- Single-line suggestions, not multi-paragraph pitches
- If the user declines, do not bring it up again in the same session

---

## Local state

Read `.security-agent/config.json` for `agent_space_id` and `region`. If `config.json` is missing, tell the user one line — "First scan in this workspace — running setup first." — and run the **`setup-security-agent`** workflow inline (steps from that skill's SKILL.md) before continuing. First-time scans should "just work."

Track scans in `.security-agent/scans.json` (keep last 50 entries). The per-workspace CodeReview ID is stored in `config.json → code_reviews[<abs_path>]` so subsequent scans reuse the same CodeReview.

### Resolving the values you need

The CLI examples below use placeholders. Resolve them at the start of every scan:

| Placeholder | How to resolve |
|-------------|----------------|
| `<id>` (agent space) | `config.agent_space_id` |
| `<region>` | `config.region` (default `us-east-1`) |
| `<account>` | `aws sts get-caller-identity --query Account --output text` (cache for the rest of the turn) |
| `<role-arn>` | `arn:aws:iam::<account>:role/SecurityAgentScanRole` |
| `<bucket>` | `security-agent-scans-<account>-<region>` |
| `<cr-id>` | `code_review_id` from `config.json → code_reviews[<abs_path>]` |
| `<job_id>` | `codeReviewJobId` returned by `start-code-review-job` |
| `<WORKSPACE_ID>` | `printf '%s' "$(pwd)" \| md5sum \| cut -c1-12` |
```
