| Severity | High — generated pipeline is rejected by GitLab CI as invalid |
| Repro | python -m cli.scaffold_gitlab --name app --type deploy --languages python |
| Symptom | stages: [] — no stages, no jobs |
| Root Cause | The deploy stage is only appended inside if args.kubernetes:. A non-k8s deploy pipeline has zero stages. |

| Severity | Medium — manifest passes schema check but is semantically empty |
| Repro | python -m cli.scaffold_sre --name svc --slo-type error_rate |
| Symptom | slo.yaml contains slos: [] — Sloth/OpenSLO tooling receives no SLO objectives |
| Root Cause | generate_slo_manifest() only branches on availability and latency. error_rate is a declared valid choice in the CLI --slo-type argument but has no generator branch. |
| Expected | An error_rate SLO entry should be generated with an appropriate SLI query |

| Severity | Low — functional gap, not a crash |
| Repro | Inspect generate_argocd_config signature — allow_any_source_repo absent |
| Symptom | MCP callers (Claude, ChatGPT) cannot opt-in to wildcard sourceRepos in AppProject even when needed |
| Root Cause | allow_any_source_repo was implemented in cli/scaffold_argocd.py (--allow-any-source-repo flag) but was never wired into the MCP server tool |

-
Fix BUG-1 (
cli/scaffold_gitlab.py): Adddeployto stages unconditionally whentype in ('deploy', 'complete'), and add a genericdeployjob (e.g., Docker push) for non-k8s deploy scenarios. -
Fix BUG-2 (
cli/scaffold_sre.py): Addelif args.slo_type in ("error_rate", "all"):branch ingenerate_slo_manifest()that generates an error-rate SLO entry using HTTP 5xx / total ratio. -
Fix BUG-3 (
mcp_server/server.py): Addallow_any_source_repo: bool = Falsetogenerate_argocd_config()signature and pass it to theargparse.Namespace. Updateskills/openai_functions.jsonandskills/claude_tools.jsonaccordingly. -
Improve GHA YAML output: The YAML serializer currently emits YAML anchors (
&id001,*id001) for repeated label dicts. GitLab and GitHub Actions parse YAML anchors correctly, but some tooling may not. Consider usingyaml.Dumperwith explicit style or flattening labels. -
Pin action versions: Generated workflows use
actions/checkout@v3andactions/upload-artifact@v3. Consider updating to@v4for security maintenance.
