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.

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 | $0.00222 | $0.01466 |
| Opus 5 | $0.00111 | $0.00733 |
| Sonnet 5 | $0.00044 | $0.00293 |
| Haiku 4.5 | $0.00022 | $0.00147 |
Grade A, and why
aws-observability 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 6d 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.

AWS Observability
Overview
Domain expertise for AWS observability across metrics, logs, and traces, covering the full lifecycle: enabling/onboarding a service to Application Signals using ADOT (AWS Distro for OpenTelemetry) auto-instrumentation SDKs and ServiceEvents — making the service show up in Application Signals — on EC2, ECS, EKS, and Lambda in Python, Node.js, Java, and .NET.
Works best with the AWS MCP server — enables running CLI commands, querying CloudWatch, and validating configurations directly. All guidance also works with standard AWS CLI access.
Note: Reference files contain specific runtime versions, quota values, and feature matrices that may change. When precision matters (e.g., deploying to production, choosing a runtime, or checking a quota), confirm values against current AWS documentation rather than relying solely on the values in these files.
Routing
| User need | Action |
|---|---|
| Enabling/onboarding a service to Application Signals (auto-instrumentation) | Read application-signals-onboarding.md |
| Propagating ServiceEvents git/deployment metadata through CI/CD | Read application-signals-cicd-metadata.md |
| Per-platform/per-language enablement steps | Read the matching references/appsignals-guides/<platform>-<language>.md (e.g. eks-python.md) |
| Writing Log Insights queries | Read log-insights.md |
| Configuring alarms (metric, composite, anomaly) | Read alarms.md |
| Publishing custom metrics or using EMF | Read metrics.md |
| Setting up X-Ray tracing or ADOT | Read tracing.md |
| Building dashboards | Read dashboards.md |
| Debugging observability issues | Read troubleshooting.md — starts with the 5 most common fixes |
| Debugging canary failures | Read synthetics.md — see Common failures table |
| CloudTrail operational auditing | Read cloudtrail.md |
| Setting up Lambda monitoring with CDK | Use alarm-template.ts as a starting point |
| Creating synthetic canaries | Read synthetics.md |
| Configuring ADOT collector | Use otel-config.yaml as a starting point |
| Debugging a running service with breakpoints/snapshots — Dynamic Instrumentation (modifies live services and capture live data) | Read dynamic-instrumentation.md in full before acting. Confirm with the user before any create/delete, and narrate before significant actions: observation → hypothesis → proposed action → expected result. Diagnosing running-service root cause from source/code inspection. Source inspection alone identifies hypotheses, not confirmed root causes. Keep suspected causes tentative until runtime evidence confirms them. |
| Spans multiple areas | Read the most specific reference first, then consult others as needed |
What ships with it
55 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

aws-observability is a skill published in the GitHub repository aws/agent-toolkit-for-aws (2,533 stars, last pushed today), licensed Apache-2.0. It adds 222 tokens to every session and 1,466 once invoked, about $0.0011 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.
