ci-debugger

ci-debugger is a skill for Claude Code, Codex from lfyxhappy/lfcode. It costs 85 tokens per session (331 once invoked), scanned A, original, MIT.

A guide for finding the first useful cause of a failed build, test, packaging, deployment, or continuous-integration job. Continuous integration, or CI, automatically checks code in a hosted pipeline.

In plain words
What is it for?
It helps diagnose failing pipeline stages, reproduce them locally, apply the narrowest correction, and verify whether a remote retry is still needed.
Why use it?
It avoids chasing later error messages, blindly retrying jobs, or changing code when the problem is infrastructure. It compares logs, configuration, inputs, caches, and local reproduction before suggesting a fix.

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-debugger 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.

What it actually says

CI Debugger

Reduce a failed pipeline to its first actionable cause and verify the narrowest repair.

Workflow

  1. Identify the pipeline, revision, job, platform, first failing step, and whether the failure is deterministic, flaky, or infrastructure-related.
  2. Read workflow configuration, task scripts, lockfiles, environment assumptions, artifact paths, and relevant logs with sensitive values redacted.
  3. Reproduce locally or in the closest safe environment using the same command, runtime version, inputs, and cache conditions when feasible.
  4. Isolate the first causal error, implement the narrowest authorized correction, and add a regression check when the cause is in repository behavior.
  5. Verify the repaired command or pipeline stage and state whether a remote retry remains necessary.

Boundaries

  • Do not retry, cancel, rerun, edit secrets, or alter hosted CI settings without explicit authorization.
  • Do not mistake a later cascade error for the root cause.
  • Do not paste tokens, signed URLs, customer data, or full secret-bearing logs into output.

Completion Check

Report the failed stage, root cause evidence, change made or recommended, local verification, and any remaining remote validation.

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.

ci-debugger is a skill published in the GitHub repository lfyxhappy/lfcode (2 stars, last pushed 1mo ago), licensed MIT. It adds 85 tokens to every session and 331 once invoked, about $0.0003 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 2026-09-05.
