oss-debug-ci

oss-debug-ci is a skill for Claude Code, Codex from chiruu12/OSS-Skills. It costs 91 tokens per session (2,501 once invoked), scanned A, original, MIT.

A guide for diagnosing failed continuous integration (CI) checks, the automated builds and tests that run on a code change. It reads pipeline settings and failure logs, then helps identify the cause.

In plain words
What is it for?
Use it to investigate failed GitHub Actions, CircleCI, or other CI checks, reproduce failures locally, and plan a fix in an open-source repository.
Why use it?
It removes the guesswork from unfamiliar CI systems and helps distinguish a problem in your code from a flaky or already-broken pipeline.

    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.

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

oss-debug-ci 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 10d 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.

Debug CI

CI failed on someone else's repo and the error makes no sense. This skill teaches you to read CI pipelines, classify failures, and fix them — instead of pushing blind patches and hoping.

Purpose

CI failures in unfamiliar repos are disorienting. The error might come from a linter you've never configured, a test runner with custom settings, or a platform-specific incompatibility. Most contributors respond by pushing random fixes until green. This skill teaches you to read the pipeline, understand what failed and why, determine if it's your fault, and fix it systematically.

When to Use

  • CI fails on your PR and you don't understand the error
  • CI failure is in a tool/system you haven't used before
  • You suspect the failure is pre-existing (flaky test, broken main)
  • You need to reproduce a CI failure locally
  • NOT when setting up CI for a new project — that's infrastructure work
  • NOT when CI passes but the code is wrong — that's oss-contribute

Prerequisites

  • A PR submitted to an OSS repo (from oss-submit-pr)
  • gh CLI authenticated
  • Access to the CI logs (public repo or you have permissions)

Process

1. Identify the CI system and read the config

Before looking at logs, understand the pipeline structure.

# Find CI configuration files
ls -la .github/workflows/ 2>/dev/null
ls -la .circleci/ 2>/dev/null
ls -la .travis.yml Jenkinsfile .gitlab-ci.yml .buildkite/ azure-pipelines.yml 2>/dev/null

# Read the relevant workflow
cat .github/workflows/ci.yml  # or whatever the CI config is

Map the pipeline:

  • What jobs exist? (build, test, lint, typecheck, etc.)
  • What order do they run in? (parallel or sequential?)
  • What OS/container do they run on? (ubuntu, macos, windows, custom image?)
  • What language/tool versions are pinned? (node 20, python 3.12, go 1.22?)
  • What caching is used? (dependency caching, build caching?)

2. Fetch the failure logs

Your PR's CI runs on the upstream repo, not on your fork. Name the repo on every command. Without -R, gh guesses from your remotes, and in a fork clone it can guess your fork, which has no runs for this PR.

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.
