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.

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 | $0.00062 | $0.00365 |
| Opus 5 | $0.00031 | $0.00182 |
| Sonnet 5 | $0.00012 | $0.00073 |
| Haiku 4.5 | $0.00006 | $0.00036 |
Grade A, and why
debugging-lambda-timeouts 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.
What it actually says
Debugging Lambda Timeouts
Overview
Domain expertise for systematically investigating AWS Lambda function timeout failures by analyzing function configuration, CloudWatch logs, metrics, dependencies, cold start patterns, and code. Identifies common causes such as insufficient timeout settings, external service delays, database connection issues, memory constraints, and inefficient code patterns, then provides prioritized recommendations.
Debug a Lambda timeout
To investigate and resolve Lambda timeout issues, follow the procedure exactly. See Lambda timeout debugging procedure.
The procedure collects function configuration, CloudWatch metrics and logs, dependency analysis, and cold start patterns. If Lambda code is provided, it also reviews the code for timeout-prone patterns. Results are compiled into a structured debugging report with prioritized recommendations.
Troubleshooting
Function not found
Verify the function name and region. Use aws lambda list-functions --region <region>
to list available functions.
No logs available
The function may not have been invoked recently or logging may be disabled. Check the function's log group configuration and invocation metrics.
Access denied errors
Verify AWS credentials have permissions for Lambda, CloudWatch Logs, and CloudWatch Metrics. See the full procedure for details.
Log query time range issues
If CloudWatch Logs Insights queries fail with time range errors, reduce the analysis window or check log group retention settings. See the full procedure for details.
What ships with it
1 file 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.

debugging-lambda-timeouts is a skill published in the GitHub repository aws/agent-toolkit-for-aws (2,569 stars, last pushed yesterday), licensed Apache-2.0. It adds 62 tokens to every session and 365 once invoked, about $0.0003 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 2026-09-03.
