aws-lambda-java-integrationProvides AWS Lambda integration patterns for Java with cold start optimization.
AWS Lambda Java Integration is an agent skill from giuseppe-trisciuoglio/developer-kit. Provides AWS Lambda integration patterns for Java with cold start optimization. Use when deploying Java functions to AWS Lambda, choosing between Micronaut and Raw Java approaches, optimizing cold starts below 1 second, configuring API Gateway or ALB integration, or implementing serverless Java applications. Triggers include "create lambda java", "deploy java lambda", "micronaut lambda aws", "java lambda cold start", "aws lambda java performance", "java serverless framework".
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/micronaut-lambda.md`, `references/raw-java-lambda.md` and `references/serverless-deployment.md`).
It sits in Backend & APIs, covering Serverless, Microservices and Third-party API integration. It works with Java, AWS Lambda and Amazon Web Services. The repository describes itself as: Modular plugin marketplace for Claude Code and agentic CLIs, with validated, spec-driven skills, agents, commands, and workflows for Java, TypeScript, Python, PHP, AWS, and AI. The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit fe73fb3. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBashGlobGrepFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are java and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
AWS Lambda Java Integration loads about 1.9k tokens when it runs, and up to ~30k if it reads all its reference files. Until then it costs about 127 tokens; SKILL.md has 525 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Write, Edit, Bash, Glob, GrepAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

This skill provides complete patterns for AWS Lambda Java development, covering two main approaches:
Both approaches support API Gateway and ALB integration with production-ready configurations.
| Approach | Cold Start | Best For | Complexity |
|---|---|---|---|
| Micronaut | < 1s | Complex apps, DI needed, enterprise | Medium |
| Raw Java | < 500ms | Simple handlers, minimal overhead | Low |
Validate: Confirm the approach fits your use case before proceeding.

Run `npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-lambda-java-integration -a claude-code`. Or copy the skill folder (plugins/developer-kit-java/skills/aws-lambda-java-integration in giuseppe-trisciuoglio/developer-kit) into .claude/skills/aws-lambda-java-integration in your project. Claude Code loads it when a task matches its description.

Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add giuseppe-trisciuoglio/developer-kit --skill aws-lambda-java-integration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/aws-lambda-java-integration, .gemini/skills/aws-lambda-java-integration, .github/skills/aws-lambda-java-integration and .opencode/skills/aws-lambda-java-integration in your project.
SKILL.md names no scripts, command-line tools or credentials: AWS Lambda Java Integration is instructions for the agent only. Our summary lists: Python 3; Node.js. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash, Glob, Grep.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
AWS Lambda Java Integration is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 28k tokens, read only when the agent opens those files.
