gruntwork-io/terragrunt: technical due diligence, read from its repository
What Borehole read in gruntwork-io/terragrunt's code and history at 1766711: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

What the repository says
- Releases are cut from another branch than the one surveyed
Architecture & Codebase — including AI provenance
strongpkg/config/dependency.go is 2,863 lines, 190× this codebase's median file
adequateThe median source file here is 15 lines. 20 files exceed 1,000 lines, the largest being 2,863. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.
pkg/config/dependency.go:1 — 2,863 lines (190× median) |
pkg/config/config.go:1 — 2,855 lines (190× median) |
internal/remotestate/backend/s3/client.go:1 — 2,792 lines (186× median) |
internal/view/tui/form/form.go:1 — 2,580 lines (172× median) |
pkg/config/stack.go:1 — 2,364 lines (157× median) |
Engineering Process & SDLC Maturity
adequate6% of recent commits change more than 2,000 lines
adequate91 of 1648 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.
| 91 commits over 2,000 lines |
Product & Engineering Maturity
adequate105 direct dependencies in a single manifest
adequatego.mod declares 105 direct dependencies. Each one is a maintenance obligation, a supply-chain surface and a potential licence question that transfers with the asset. The count says nothing about whether any given dependency was a good choice; it says how many such choices a buyer inherits.
go.mod — 105 declared |
Releases are cut from another branch than the one surveyed
adequateThe newest release, v1.1.6, is not on the branch this survey read; the newest release on it is v1.1.5. The shipped product may differ from what this report describes. Survey the release branch too.
| tag v1.1.6 |
Security & Reliability Posture
adequate9 credential-shaped strings in the tree sit in tests, examples, documentation or local development settings
adequateStrings shaped like credentials appear only where fakes are usual: test fixtures, examples, documentation, placeholders and local stacks. They are almost always fakes. Ask someone to confirm that none of them works anywhere, because a real key in a development file is still a real key.
| 3 cited: AWS access key, where fakes are usual |
| Slack token, where fakes are usual |
| private key block, where fakes are usual |
