ci-debug

A helper for finding why GitHub Actions, GitHub's automated build and test service, has reported a failed workflow.

In plain words
What is it for?
Use it to inspect a pull request or workflow run, identify likely root causes, and suggest fixes for common Python and Node.js CI errors.
Why use it?
It brings together failed checks and error logs so you do not have to search through CI output manually.

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-debug 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.

CI Debug — Analyse des echecs CI

Contexte dynamique

  • Checks PR en cours: !gh pr checks 2>/dev/null | head -20
  • Workflows recents: !gh run list --limit 5 --json name,status,conclusion,headBranch --template '{{range .}}{{.name}} | {{.status}} | {{.conclusion}} | {{.headBranch}}{{"\n"}}{{end}}' 2>/dev/null

Instructions

Analyser l'echec CI pour: $ARGUMENTS

Step 1: Identifier le workflow en echec

Si c'est un numero de PR:

gh pr checks $0
gh run list --branch $(gh pr view $0 --json headRefName -q .headRefName) --limit 3

Si c'est une URL de workflow run:

gh run view $0 --log-failed

Step 2: Extraire les logs d'erreur

gh run view <run-id> --log-failed 2>&1 | head -100

Chercher les patterns:

  • error, Error, ERROR
  • FAIL, FAILED
  • exit code 1, exit code 2
  • denied, forbidden, unauthorized

Step 3: Diagnostiquer

Causes frequentes dans STOA CI:

Pipeline Erreur frequente Cause Fix
Python CI I001 import order isort non respecte ruff check --fix
Python CI mypy type error Type hints manquants Ajouter les annotations
Node CI vitest fail Mock MSW manquant Ajouter handler MSW
Node CI eslint warnings Max warnings depassé (0 pour UI, 20 pour portal) Fixer les warnings
Docker buildx fail Cache layer miss ou multi-arch Verifier --platform linux/amd64,linux/arm64
Helm helm lint fail Values manquantes, indentation Verifier values.yaml
Security dependency-review GitHub Advanced Security non active Connu, non-bloquant
K8s deploy kubectl apply fail Selector immutable, Kyverno block Voir .claude/docs/k8s-deploy.md
K8s deploy rollout timeout maxSurge/maxUnavailable deadlock maxUnavailable: 1, maxSurge: 0

Step 4: Proposer le fix

Pour chaque erreur identifiee:

  1. Fichier exact a modifier (chemin complet)
  2. Diff propose (old → new)
  3. Commande de verification locale
  4. Impact sur les autres workflows

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-debug is a skill published in the GitHub repository stoa-platform/stoa (5 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 28 tokens to every session and 881 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
