Audits caterpillar against the 49-item engineering best-practices checklist: raw 7/49, adjusted compliance 40%. No docs/ directory exists in this repo, so the report is placed at the repo root per the skill's fallback rule.

- Typo: “dependancies” → “dependencies”.
| 47 | Dependency update automation | **Met** | "Pattern Security Automation" (Wiz-backed) opens CVE auto-remediation PRs — e.g. #78 (`CVE-2026-32287`, antchfx/xpath) and #80 (`CVE-2026-54063`, xuri/excelize/v2); both PRs were closed rather than merged directly, but `go.mod` shows both packages already at or past the fixed versions (`xpath v1.3.8`, `excelize v2.11.0`), and `gh api .../dependabot/alerts` shows 20 alerts (7 critical, 4 high, 9 medium), all in `state: fixed` | The team is actually keeping up with flagged CVEs (via other PRs, e.g. #90 "chore: upgrade dependancies"), even though the automation's own PRs aren't the merge path — worth tightening so the auto-PR is the actual fix path rather than a duplicate signal. |

| Caterpillar is a Go data-ingestion and processing pipeline tool (module `github.com/patterninc/caterpillar`, Go 1.25) — a single CLI binary that runs YAML-defined pipelines chaining task types (HTTP, S3, SQS, SNS, Kafka, SFTP, JQ, XPath, converters, etc.). It has no browser UI and no database of its own; persistence, when it happens, is in the external systems its tasks talk to. It ships two ways: a GitHub Release binary (`.github/workflows/release.yaml`) and a multi-arch Docker image pushed to Docker Hub (`patternoss/caterpillar`) — there is no Terraform, ECS, or Lambda config in this repo, so how/where the binary or image is actually run in AWS could not be verified from this repo alone (it is registered in Backstage as a `service` owned by `dev-data-acquisition`, `Environment: stage`). It integrates heavily with AWS (S3, SQS, SNS, SSM Parameter Store, Kafka via confluent-kafka-go), so AWS-adjacent items are judged against that integration surface even without in-repo deploy config. 14 people have committed (`git shortlog`), so this is a small-team-owned, actively developed repo, not a solo project. No `.agents/pattern-agents.json` or sibling manifest, no `AGENTS.md`/`CLAUDE.md`, no `docs/` directory — documentation lives in a top-level `README.md`, `DAG_README.md`, and 22 per-task-type `README.md` files under `internal/pkg/pipeline/task/*/`. |
| | 11 | Formatters (Prettier, gofmt, Black) | **Partial** | `gofmt -l .` on the checked-out tree returns no files (code is already gofmt-clean) | The convention is followed in practice but nothing enforces it going forward — no CI step or pre-commit hook runs `gofmt -l`/`gofmt -s`. | | ||
| | 12 | Type checking (TypeScript strict, mypy) | **Met** | Go's compiler performs static type checking on every build; `.github/workflows/ci.yaml`'s `go build` step exercises this on every PR | Equivalent credited per Step 3 rule 1 — Go's own compiler is the type checker here. | | ||
| | 13 | Pre-commit hooks | **Gap** | No `.pre-commit-config.yaml` or `.githooks/` found | — | | ||
| | 14 | Commit message conventions | **Partial** | `git log --oneline` shows a mix: some Conventional Commits (`fix(jq): ...`, `feat(http task): ...`) alongside many all-caps prefixes (`FEAT:`, `FIX:`, `HOTFIX:`, `REFACTOR:`) and plain messages (`chore: upgrade dependancies`) | No enforcement (no commitlint, no CI check) — recommend standardizing on the Conventional Commits style already used by several recent commits. | |
