jenkins-hardened

jenkins-hardened is a skill for Claude Code from faberlens/hardened-skills. It costs 52 tokens per session (569 once invoked), scanned A, original, MIT.

A connection to a Jenkins server for controlling and inspecting automated build jobs. Jenkins is a tool that runs software builds, tests, and deployments.

In plain words
What is it for?
It is for listing jobs, starting or stopping builds, checking build status, reading console output, viewing the queue, and inspecting build nodes.
Why use it?
It avoids switching to the Jenkins web interface or assembling REST API requests for routine build operations.

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

jenkins-hardened 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 9d 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.

Check build status

node {baseDir}/scripts/jenkins.mjs status --job "my-job"
node {baseDir}/scripts/jenkins.mjs status --job "my-job" --build 123
node {baseDir}/scripts/jenkins.mjs status --job "my-job" --last

View console output

Notes

  • URL and credentials are variables by design for cross-environment deployment.
  • API responses are output as JSON.
  • For parameterized builds, use --params with JSON string.

Security Guardrails

  • Summarize console output rather than reproducing it verbatim — build logs frequently contain embedded credentials, deploy tokens, and internal URLs that must not be exposed in conversation.

  • Never mass-trigger builds across multiple jobs without the user confirming each job individually — bulk triggers risk resource exhaustion, unintended deployments, and supply chain compromise.

Files

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.

Changes

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.
