quarkus-workshop-langchain4j: Skill for Claude Code

.agents/skills/workshop-docs-style/SKILL.md

workshop-docs-style is a skill for Claude Code, Codex from quarkusio/quarkus-workshop-langchain4j. It costs 53 tokens per session (6,261 once invoked), scanned A, original, Apache-2.0.

A writing guide for Quarkus LangChain4j workshop documentation, covering tone, structure, and practical explanations. Quarkus is a Java framework, and LangChain4j is a library for connecting Java applications to language models.

In plain words
What is it for?
Use it whenever writing or editing files under the workshop's documentation directory.
Why use it?
It keeps workshop pages consistent and readable for developers instead of relying on generic documentation style.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is quarkusio/quarkus-workshop-langchain4j's own configuration. It tells Claude Code and Codex how to work on quarkus-workshop-langchain4j itself, so it is not a mod to install elsewhere.

Token cost

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.

Security

Grade A, and why

workshop-docs-style 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 21d 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.

Workshop Documentation Style Guide

This guide captures the conventions established for the Quarkus LangChain4j workshop docs. It is self-contained for contributors to this repository; repeat a general writing rule here when workshop authors need it. The reference voice is Section 1, which was written by the project owner without AI assistance.

Voice and Tone

Write as a technical instructor talking to a developer sitting in front of their laptop. Be direct and practical. Avoid corporate enthusiasm ("Congratulations!", "Great!", "Easy right?") unless a brief one-liner fits naturally at the end of a section. Don't start pages with "In this step you will learn..." laundry lists.

Stay in the reader's exercise

Keep learner-facing prose about the business scenario, system behavior, and actions the reader can take. Do not insert workshop-author commentary about how chapters are being built, what is planned or omitted, or which features have not been implemented. For example, delete asides such as "The section will build toward checking offers with external services, but the current planner has no extras catalog or reservation service." Keep roadmap and implementation-status details in planning documents. An unfinished chapter can retain one short "Coming soon" notice without repeating that status throughout its prose.

Do not narrate our local testing history or conversations with the project owner. Dates, model-specific outcomes, run identifiers, incidental screenshot details, and accounts of what worked during author testing belong in maintenance notes, not the tutorial. Explain what the reader should inspect and why. Preserve setup instructions and limitations that affect the exercise, such as a simulated booking, state lost on restart, or a price covering vehicle rental only. Put these beside the relevant action instead of adding general disclaimers to the scenario.

Connected prose

Concise does not mean a succession of short, abrupt sentences. Develop each paragraph around a connected idea, using cause, contrast, or sequence to help one sentence lead into the next. Vary sentence length naturally, without turning every explanation into either clipped statements or one long sentence.

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.
