ci-debugging

ci-debugging is a skill for Claude Code from bdfinst/agentic-dev-team. It costs 59 tokens per session (1,250 once invoked), scanned A, original, MIT.

A method for diagnosing failures in continuous integration and delivery pipelines. CI/CD is the automated process that builds, tests, and sometimes releases code.

In plain words
What is it for?
Investigating broken builds, failing pipelines, environment differences, and tests that pass locally but fail in CI.
Why use it?
It replaces guesswork and repeated retries with a specific explanation that can be checked against the failure and the local environment.

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

ci-debugging 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 1mo 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.

CI Debugging

Overview

CI failures are diagnosed systematically, not by guessing. This skill prevents the common anti-pattern of "just re-run it" by enforcing a hypothesis-first approach.

Constraints

  • Never suggest "retry the build" as a first action
  • Never add retry logic to "fix" a flaky test
  • Never push a speculative fix without reproducing locally first
  • Always form a hypothesis before making changes

Process

1. Read the failure

Read the full CI log output. Identify:

  • What failed: test, lint, typecheck, build, deploy, or infrastructure
  • When it started failing: this commit, recent merge, or intermittent
  • Error message: exact error text, not a summary

2. Form a hypothesis

Before touching any code, state a hypothesis: "I believe X is failing because Y, and I can verify by Z."

Good hypotheses are specific and falsifiable:

  • "The test fails because the database migration added a NOT NULL column and the test fixture doesn't set it"
  • "The build fails because Node 20 dropped support for this API and CI upgraded last week"

Bad hypotheses:

  • "Something is wrong with the tests"
  • "CI is flaky"

Graph-assisted hypothesis grounding. Prefer CodeGraph/Repowise over raw Grep for locating the actual source/test code behind the failing log line before stating the hypothesis. See knowledge/codegraph-vs-graphify.md for tool selection and the fallback contract.

3. Environment delta analysis

Compare local vs CI environments using this checklist:

Factor Check
Runtime version Node, Python, Go, JDK, Ruby, .NET — exact version match?
OS and architecture macOS vs Linux, x86 vs ARM?
Dependency resolution Lockfile committed? Registry differences? Private packages accessible?
Environment variables All required vars set? Secrets populated?
Parallelism Tests run in parallel in CI but serial locally? Shared state?
Memory/CPU CI runner constrained? OOM killer?
Network External service dependencies? DNS resolution? Firewall rules?
Filesystem Case sensitivity (macOS vs Linux)? Temp directory permissions? Path length?
Timezone/locale Date formatting tests? Locale-dependent string comparisons?
Docker Image tag latest drifted? Layer cache stale? Build context different?

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.

ci-debugging is a skill published in the GitHub repository bdfinst/agentic-dev-team (295 stars, last pushed 4d ago), licensed MIT. It adds 59 tokens to every session and 1,250 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
