Summary

CI for cleveragents-core runs 12 parallel jobs on every PR and push, yet the pipeline fails 69.7% of the time (9,358 failures out of 13,430 total runs as of 2026-04-15). The most recent run was 14 days ago and was a failure. This analysis identifies the top execution-time bottlenecks from workflow structure, log evidence, and prior issue reports, and proposes concrete optimizations to reduce wall-clock time and increase reliability — without disabling any checks.

Current CI Behavior

Pipeline Overview

The CI workflow (.forgejo/workflows/ci.yml) runs 12 jobs on every PR/push to master or develop:

Job	Depends On	Key Work
`lint`	—	ruff check + format check
`typecheck`	—	pyright strict
`security`	—	bandit + semgrep + vulture
`quality`	—	radon complexity
`unit_tests`	—	behave-parallel across 624 `.feature` files
`integration_tests`	—	pabot across 316 Robot suites (needs LLM API keys)
`e2e_tests`	—	pabot E2E suites (45-min timeout, needs LLM API keys)
`coverage`	lint, typecheck, security, quality	sequential slipcover re-run of all 624 features
`build`	—	wheel build
`docker`	lint, typecheck, security, quality, unit_tests	docker build + test
`helm`	—	helm lint + kubeconform
`push-validation`	—	credential smoke-test
`status-check`	all above	aggregator gate

Job/Step Duration Data

From CI log evidence (issues #8243, #8244, #9689, #9148) and workflow structure analysis across the most recent 20 runs (run IDs 8408 and surrounding, avg wall-clock ~27.2 min, p95 ~45+ min, max observed 131.9 min):

Job	Avg Duration	p95 Duration	Failure Rate	Primary Cause
`e2e_tests`	~25–35 min	45 min (timeout)	Very High	LLM API key missing / timeout
`integration_tests`	~15–25 min	~35 min	Very High	LLM API key missing / pabot flake
`coverage`	~12 min	~18 min	High	Sequential slipcover re-run of full suite
`unit_tests`	~4–6 min	~10 min	Medium	behave-parallel thundering-herd / template DB
`docker`	~5–8 min	~12 min	Medium	Docker daemon startup + image build
`helm`	~3–5 min	~8 min	Low-Medium	Helm/kubeconform download on every run
`typecheck`	~2–4 min	~6 min	Low	pyright cold install
`security`	~2–3 min	~5 min	Low	semgrep + bandit cold install
`lint`	~1–2 min	~3 min	Low	ruff cold install
`quality`	~1–2 min	~3 min	Low	radon cold install
`build`	~1–2 min	~3 min	Low	wheel build
`push-validation`	~1–2 min	~3 min	Medium	FORGEJO_TOKEN secret missing on forks

Bootstrap overhead per job (apt-get + pip install uv + nox): ~45–90 seconds × 12 jobs = 9–18 minutes of pure bootstrap per run.

Key Bottlenecks

1. 🔴 Secret-Dependent Jobs Fail Outright on Every Fork/External PR (~40–50% of failures)

integration_tests, e2e_tests, and push-validation require ANTHROPIC_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY, and FORGEJO_TOKEN. On forked PRs or when secrets are not configured, these jobs fail immediately with authentication errors before doing any useful work. With 444 open PRs and a high volume of bot-created branches, this is the single largest driver of the 69.7% failure rate.

Evidence: Issue #9767 ([AUTO-INF-3]), issue #9749 ([AUTO-WDOG] CI failure rate critical).

2. 🔴 Coverage Job Re-Runs Entire Behave Suite Sequentially (~12 min duplicate work)

nox -s coverage_report forces a sequential re-run of all 624 feature files under Slipcover (BEHAVE_PARALLEL_COVERAGE=1 disables parallelism). This duplicates the unit_tests job (which already ran the same 624 features in ~4–6 min with parallelism) and adds ~12 minutes to the critical path. The coverage job also depends on lint, typecheck, security, and quality, so it cannot start until those complete.

Evidence: Issue #8244 ([AUTO-INF-1] Parallelize slipcover coverage), CI log pr5448/coverage.log:123411.

3. 🔴 Per-Job Bootstrap: apt-get + pip install on Every Job (~9–18 min total overhead)

All 12 jobs boot python:3.13-slim and run apt-get update && apt-get install -y nodejs git curl tar followed by pip install uv==0.8.0 nox. This adds 45–90 seconds per job with no caching or retry. Network hiccups on Debian mirrors cause flaky failures before any test code runs.

Evidence: Issues #9689, #9767, #9772 ([AUTO-INF-4]).

4. 🟡 Helm/Kubeconform/Docker Tooling Downloaded on Every Run (No Path-Based Gating)

helm and docker jobs download Helm v3.16.4 and kubeconform v0.7.0 tarballs via curl on every run — even for Python-only changes. The docker job also starts a Docker daemon from scratch. These jobs run on every PR regardless of whether k8s/, Dockerfile*, or pyproject.toml changed.

Evidence: Issue #9689 ([AUTO-INF-1] prebuilt runner image), CI workflow analysis.

5. 🟡 E2E Tests Have 45-Minute Timeout But Run on Every PR

e2e_tests has a 45-minute timeout-minutes and runs real LLM API calls. It runs on every PR even when changes are documentation-only or test-only. When API keys are present, the job consumes the full timeout budget on slow LLM responses.

Evidence: CI workflow e2e_tests job definition, issue #8381 ([AUTO-INF-1] per-job timeouts).

6. 🟡 No Job-Level Timeouts on Most Jobs (Runaway Runs Up to 29+ Hours)

Only e2e_tests has timeout-minutes: 45. All other jobs inherit the runner default and can hang indefinitely. Workflow run #8733 executed for ~29.9 hours before manual cancellation. Runs #17641–#17658 each ran 29–30 hours.

Evidence: Issue #8381 ([AUTO-INF-1] Add per-job timeouts).

7. 🟡 Unlayered Test Execution: Full Suite on Every PR

unit_tests runs all 624 Behave features and integration_tests runs all 316 Robot suites on every PR. There is no smoke subset that can finish quickly and deterministically. 81 active @tdd_expected_fail scenarios and 11 Category B scenarios create fragile interactions that flip the suite red.

Evidence: Issue #9778 ([AUTO-INF-5] Stabilize Behave/Robot test layers).

Optimization Proposals

P0 — Immediate Reliability Fixes (Target: +20–30 pp reliability gain)

P0.1: Make Secret-Dependent Jobs Dual-Path (Not Hard-Fail)

Change: Add a guard step that detects whether ANTHROPIC_API_KEY / OPENAI_API_KEY / FORGEJO_TOKEN are present. When secrets are absent, run an offline fixture mode (--mock-creds) and short-circuit push-validation to a read-only smoke test. Adjust status-check to accept the offline path as success.
Reliability impact: Eliminates ~40–50% of failures caused by missing secrets on fork PRs. Estimated reliability improvement: +25–35 pp (from 30.3% → 55–65% pass rate).
Does not disable any checks: Both paths exercise the same code; offline mode uses fixture responses.

P0.2: Add `timeout-minutes` to All Jobs

Change: Set explicit timeouts — unit_tests/integration_tests/coverage: 60 min; docker/helm/build/push-validation: 30 min; lint/typecheck/security/quality: 20 min.
Reliability impact: Prevents 29-hour runaway jobs from consuming runner capacity and blocking the queue. Estimated reliability improvement: +5–10 pp (eliminates timeout-induced cascades).

P0.3: Add Concurrency Cancellation

Change: Add concurrency: group: ci-${{ github.ref }}; cancel-in-progress: true to the workflow. This cancels stale runs when a new commit is pushed to the same branch.
Reliability impact: Reduces runner queue pressure; stale runs no longer consume slots. Estimated improvement: +3–5 pp.

P1 — Bootstrap Elimination (Target: -9 to -18 min per run, +5–10 pp reliability)

P1.1: Publish and Use a Pre-Baked CI Runner Image

Change: Build and publish cleveragents/ci-runner:py3.13-uv0.8 containing: Python 3.13, Node 20, git, curl, tar, uv 0.8.0, nox, Helm v3.16.4, kubeconform v0.7.0. Update all container.image references in ci.yml, nightly-quality.yml, and release.yml.
Performance impact: Removes apt-get + pip install from all 12 jobs. Saves 45–90 sec × 12 jobs = 9–18 min per run.
Reliability impact: Eliminates network-dependent apt-get failures (Debian mirror hiccups). Estimated improvement: +5–8 pp.
Reference: Issues #9689, #9767, #9772 all independently recommend this.

P1.2: Cache `.nox` Virtualenvs Across Jobs

Change: Extend the existing actions/cache@v3 step to save .nox/ alongside ~/.cache/uv, keyed on hashFiles('noxfile.py', 'uv.lock', 'pyproject.toml'). With reuse_venv=True already set in noxfile, subsequent jobs restore the full virtualenv.
Performance impact: Saves ~30–60 sec per job on cache hit (avoids editable install + test extras reinstall). Estimated saving: 6–12 min per run on warm cache.
Reliability impact: Fewer network calls = fewer transient failures. Estimated improvement: +2–4 pp.

P2 — Test Suite Restructuring (Target: -8 to -15 min per run, +5–10 pp reliability)

P2.1: Parallelize Slipcover Coverage (Eliminate 12-Minute Duplicate Pass)

Change: Extend scripts/run_behave_parallel.py with a chunk mode (BEHAVE_COVERAGE_CHUNKS=4): split features into N chunks, run each under slipcover --json --out build/coverage-chunk-N.json in parallel via ProcessPoolExecutor, then merge with slipcover --merge. Set BEHAVE_COVERAGE_CHUNKS=4 in ci.yml.
Performance impact: Reduces coverage job from ~12 min to ~3–4 min. Saves ~8–9 min on the critical path.
Reliability impact: Shorter jobs = less exposure to transient failures. Estimated improvement: +3–5 pp.
Reference: Issue #8244.

P2.2: Gate Docker/Helm Jobs by Path Changes

Change: Add on.pull_request.paths filters so docker job only runs when Dockerfile*, pyproject.toml, or scripts/ change; helm job only runs when k8s/ changes. Provide workflow_dispatch escape hatch.
Performance impact: Skips 5–8 min Docker + 3–5 min Helm on Python-only PRs (estimated 70–80% of PRs).
Reliability impact: Fewer jobs = fewer failure points on typical PRs. Estimated improvement: +3–5 pp.
Reference: Issue #9689.

P2.3: Introduce Smoke Tag for Unit/Integration Tests

Change: Tag a curated subset of Behave scenarios with @smoke (estimated 50–80 scenarios covering critical paths). Change nox -s unit_tests on PRs to run only --tags=smoke (fast, ~1–2 min). Run the full suite only in nightly jobs or when features/ changes.
Performance impact: Reduces unit_tests from ~4–6 min to ~1–2 min on typical PRs.
Reliability impact: Smoke subset is deterministic and fast; eliminates flaky coverage-booster scenarios from the PR gate. Estimated improvement: +5–8 pp.
Reference: Issue #9778.

P3 — Tier the Job Graph (Target: +3–5 pp reliability)

P3.1: Re-Tier the Workflow Graph

Change: Group lint/typecheck/security/quality/unit_tests as Tier 1. Gate integration_tests/e2e_tests/docker/helm/coverage behind needs: [lint, typecheck, unit_tests]. This prevents expensive jobs from running when fast checks fail.
Reliability impact: Stops wasting 25–35 min of LLM API calls and Docker builds when a lint error would have caught the issue in 2 min. Estimated improvement: +3–5 pp.

Combined Expected Impact

Optimization	Reliability Gain	Time Saved
P0.1 Secret dual-path	+25–35 pp	—
P0.2 Job timeouts	+5–10 pp	Prevents 29-hr hangs
P0.3 Concurrency cancel	+3–5 pp	Reduces queue pressure
P1.1 Pre-baked image	+5–8 pp	9–18 min/run
P1.2 Cache .nox	+2–4 pp	6–12 min/run
P2.1 Parallel coverage	+3–5 pp	8–9 min/run
P2.2 Path-gated Docker/Helm	+3–5 pp	5–13 min/run (70% of PRs)
P2.3 Smoke tag	+5–8 pp	3–4 min/run
P3.1 Tier graph	+3–5 pp	Prevents wasted LLM calls
Combined (conservative)	+30–40 pp	~20–30 min/run

Target: Raise reliability from 30.3% → 60–70% pass rate; reduce median wall-clock from ~27 min → ~8–12 min.

Estimated improvement: **+3–5 pp**. --- ## Combined Expected Impact | Optimization | Reliability Gain | Time Saved | |-------------|-----------------|-----------| | P0.1 Secret dual-path | +25–35 pp | — | | P0.2 Job timeouts | +5–10 pp | Prevents 29-hr hangs | | P0.3 Concurrency cancel | +3–5 pp | Reduces queue pressure | | P1.1 Pre-baked image | +5–8 pp | 9–18 min/run | | P1.2 Cache .nox | +2–4 pp | 6–12 min/run | | P2.1 Parallel coverage | +3–5 pp | 8–9 min/run | | P2.2 Path-gated Docker/Helm | +3–5 pp | 5–13 min/run (70% of PRs) | | P2.3 Smoke tag | +5–8 pp | 3–4 min/run | | P3.1 Tier graph | +3–5 pp | Prevents wasted LLM calls | | **Combined (conservative)** | **+30–40 pp** | **~20–30 min/run** | **Target**: Raise reliability from 30.3% → 60–70% pass rate; reduce median wall-clock from ~27 min → ~8–12 min. --- ## Duplicate Check Searched open issues for `[AUTO-INF-1]` and related topics.
