setup-agentic-scaffolding

setup-agentic-scaffolding is a skill for Claude Code, Codex from eldermoraes/quarkus-agentic-scaffolding. It costs 97 tokens per session (5,545 once invoked), scanned A, original, Apache-2.0.

A setup procedure for the Quarkus and LangChain4j agent-based AI stack. It checks or installs the required Java and development tools, registers supporting MCP servers, and adds project conventions.

In plain words
What is it for?
Use it once per machine and again for a project when preparing the toolchain, connecting the Quarkus Agents and context7 MCP servers, or creating a CLAUDE.md or AGENTS.md file.
Why use it?
It removes the manual work of checking prerequisites and configuring the coding agent before starting an AI application.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

setup-agentic-scaffolding 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 2d 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.

Setup Agentic Scaffolding

Version: 0.23.3

1. When to use this skill

Run this skill once per machine and revisit once per project to configure the prerequisites for the Quarkus + LangChain4j agentic stack — before scaffolding or auditing any project. It is the entry point of the flow:

  • Phase A — toolchain (machine-level): JDK 25+/GraalVM, JBang, a container runtime, Maven or the Quarkus CLI.
  • Phase B — MCP registration (per agent): the Quarkus Agents MCP and context7, wired through the mechanism of whichever agent is running.
  • Phase C — conventions (project-level): the always-on conventions file (CLAUDE.md or AGENTS.md) copied into the user's project root.

This skill is user-invoked only (disable-model-invocation: true); it never triggers itself from a task description.

2. Bootstrap license (read first)

The project conventions (CLAUDE.md / AGENTS.md §1) make the Quarkus Agents MCP mandatory for every Quarkus task and require stopping when required tooling is missing. That rule does not apply to this skill. Installing that tooling is precisely this skill's job, so it legitimately operates before and without the Quarkus Agents MCP and context7. Do not stop or defer to the MCP here — proceed with Phases A–C and register the MCP as part of the work.

3. How this skill works (process)

Every phase follows the same house pattern — never act blind, never clobber:

  1. Explore. Detect current state with read-only probes (command -v, mcp list, file checks).
  2. Present findings, recommendation first. Lead with the recommended action, then the evidence ("already installed vs missing"). Never claim something is installed without a probe backing it.
  3. Confirm. Get explicit user approval before any install, registration, or file write.
  4. Write / Execute, then verify. Run the step, then re-probe to prove it worked — never declare success from the command's exit alone.

The three phases are idempotent: re-running skips what is already done and only fills gaps. If a step needs a restart to take effect (Phase B), the re-run is the verification pass.

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.
