Agent Toolkit for AWS is a collection of AWS-supported MCP servers, skills, plugins, commands, and hooks that help AI coding agents build, deploy, and manage applications on AWS. It is used by developers working with AWS services through agents such as Claude Code, Codex, Cursor, and Kiro. The catalogue entries are the toolkit's own agent extensions for AWS development and operations.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 101 Data is uploaded to cloud storage (S3 / GCS / Azure Blob). This may be a legitimate backup or exfiltration to an external bucket. Manual review is recommended.Fix: Verify the destination bucket is trusted and owned by you. Never upload credentials, secrets, or workspace contents to external or unverified cloud storage.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00086 | $0.02918 |
| Opus 5 | $0.00043 | $0.01459 |
| Sonnet 5 | $0.00017 | $0.00584 |
| Haiku 4.5 | $0.00009 | $0.00292 |
Grade A, and why
scanning-with-aws-security-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 314 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scanning-with-aws-security-agent is a skill published in the GitHub repository aws/agent-toolkit-for-aws (2,559 stars, last pushed yesterday), licensed Apache-2.0. It adds 86 tokens to every session and 2,918 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
