Summary

Fixes three categories of false positives in the DependencyPinningAssessor (lock_files attribute) discovered during an organization-wide audit of 32 repositories in openshift-online.

Problem

The assessor scores 0/100 (fail) for repositories that actually have their dependencies properly managed:

  1. Multi-module repos with sub-directory lock files — repos like ocm-api-model (3 sub-modules, each with go.sum) and rosa-hcp-platform-tools (3 Go tools, each with go.sum) score 0 because lock files are only searched at the repo root
  2. Terraform repos — repos like rosa-regional-platform (18 versions.tf files with provider constraints) score 0 because .terraform.lock.hcl is not in the lock file list and versions.tf is not considered
  3. Repos with no code or dependencies — repos like homebrew-tap, mosbox, rosa-external-tests (README + LICENSE only) score 0 instead of not_applicable

Changes

1. Recursive lock file search (_rglob_filtered)

  • When no lock files found at root, recursively search subdirectories
  • Excludes vendor/, node_modules/, .venv/, .git/, .terraform/
  • Fixes multi-module Go repos, monorepos with per-package lock files

2. Terraform ecosystem support

  • Added .terraform.lock.hcl to the strict lock files list
  • Added _score_terraform_constraints() to evaluate versions.tf files as a fallback
    • Exact version pins (version = "6.0.0") -> full score
    • Range constraints (version = ">= 6.0") -> partial score (floor at 35)
    • .terraform.lock.hcl found in subdirectories -> full pass

3. not_applicable for repos without dependency manifests

  • Added _has_any_dependency_manifest() check against 17 known manifest patterns
  • Repos with no go.mod, package.json, pyproject.toml, Cargo.toml, requirements.txt, etc. return not_applicable instead of fail
  • Prevents penalizing documentation-only, config-only, or early-stage repos

Test coverage

8 new test cases added (59 total, all passing):

Test What it verifies
test_subdirectory_go_sum_multi_module go.sum in tools/mytool/ detected -> pass
test_subdirectory_lock_excludes_vendor go.sum in vendor/ ignored -> fail
test_no_dependency_manifests_returns_not_applicable README-only repo -> not_applicable
test_has_go_mod_but_no_lock_still_fails go.mod without go.sum -> fail
test_terraform_versions_tf_range_constraints >= 6.0 constraints -> score >= 35
test_terraform_versions_tf_exact_pins "6.0.0" exact pin -> pass (100)
test_terraform_lock_hcl_detected .terraform.lock.hcl at root -> pass
test_subdirectory_requirements_txt requirements.txt in subdirectory -> pass

Backward compatibility

  • No changes to attribute ID, name, weight, or tier
  • LockFilesAssessor alias preserved
  • Root-level lock file detection unchanged (still checked first)
  • Recursive search only triggers when root search finds nothing
  • All 8 existing tests continue to pass

Real-world impact

Tested against the openshift-online organization (32 repos):

Repository Before After
ocm-api-model 0/100 fail 100/100 pass (sub-module go.sum detected)
rosa-hcp-platform-tools 0/100 fail 100/100 pass (per-tool go.sum detected)
rosa-regional-platform 0/100 fail ~35/100 partial (versions.tf range constraints)
homebrew-tap 0/100 fail not_applicable
mosbox 0/100 fail not_applicable
rosa-external-tests 0/100 fail not_applicable
ocm-kafka 0/100 fail not_applicable (Containerfile only)

📝 Walkthrough

Walkthrough

The dependency pinning assessor now supports Terraform lock files and provider constraint scoring. It recursively discovers dependency manifests and lock files while excluding generated and vendor directories. It returns not_applicable for repositories without dependency manifests and expands remediation guidance.

Changes

Dependency Pinning Assessment

Layer / File(s) Summary
Filtered dependency discovery
src/agentready/assessors/stub_assessors.py, tests/unit/test_assessors_stub.py
The assessor detects nested dependency manifests and lock files. Recursive searches exclude generated, vendor, and VCS directories. Tests cover nested files, ignored vendor files, missing go.sum, and nested requirements.txt.
Terraform scoring and no-lock handling
src/agentready/assessors/stub_assessors.py, tests/unit/test_assessors_stub.py
.terraform.lock.hcl produces a passing result. Without that file, versions.tf constraints receive exact-pin or range-based scores. Repositories without manifests return not_applicable. Missing-lock remediation includes Go and Terraform steps.
Assessment documentation
docs/attributes.md
The dependency criteria document recursive discovery, Terraform fallback scoring, additional lock-file formats, and not_applicable handling.

Merge Risk: 🟡 Moderate · up to 35b1c

The change broadens dependency detection for nested modules, Terraform repositories, and dependency-free repositories, but valid manifests can still be ignored for some repository paths, container-only repositories can still receive incorrect failures, and Terraform constraints may be classified incorrectly; the documentation also shows an invalid constraint operator. These bounded assessment inaccuracies should be fixed or explicitly accepted before merge.

⚠️ Potential issue | 🟠 Major

Don’t treat Dockerfiles as lock-file dependency manifests.

Line 58 makes Dockerfile-only/container-only repos enter the “has manifests but no lock files” failure path, but this assessor’s remediation has no Docker lock-file action and container_setup is explicitly separate at Line 980. This can reintroduce false positives for config/container repos.

Optimize directory traversal to avoid walking excluded directories.

The current implementation uses Path.rglob() to traverse all directories, then filters out matches from excluded paths after traversal completes. On large repositories with deep vendor/, node_modules/, .terraform/, and other excluded directory trees, this wastes significant time traversing directories that will be discarded anyway.

Use os.walk() with in-place dirnames modification to prune excluded directories before traversal:

Proposed traversal fix
     def _rglob_filtered(self, root: Path, filename: str) -> list[Path]:
         """Recursively search for filename, excluding common non-source dirs."""
+        import os
+
         matches = []
-        for match in root.rglob(filename):
-            if not any(part in self._EXCLUDED_DIRS for part in match.parts):
-                matches.append(match)
+        for dirpath, dirnames, filenames in os.walk(root):
+            dirnames[:] = [
+                dirname
+                for dirname in dirnames
+                if dirname not in self._EXCLUDED_DIRS
+            ]
+            if filename in filenames:

Fix regex to match provider version key only, not required_version.

The current regex incorrectly captures required_version = ">= ..." alongside provider version pins. A Terraform configuration with required_version = ">= 1.5.0" and exact provider pins (e.g., version = "6.0.0") will be scored as mixed/ranged and fail (score < 75%) instead of pass (100%), causing false negatives on correctly pinned provider versions.

Use word boundaries to isolate the version key:

**Subdirectory search**: If no lock file exists at the repository root, the assessor searches subdirectories recursively (excluding `vendor/`, `node_modules/`, `.venv/`, `venv/`, `__pycache__/`, `.git/`, and `.terraform/`), so multi-module repos and monorepos with per-package lock files are recognized.

**Terraform fallback**: Repos with no lock files but with `versions.tf` provider constraints are scored on pinning quality: exact pins (`version = "6.0.0"`) count toward a full score, range constraints (`>=`, `<`, `~`, `!=`) score proportionally with a floor of 35 points.

Check exclusion directories relative to root.

match.parts includes components above the repository root. If repository.path is /work/venv/project, every nested match is discarded because its absolute path contains venv. This makes nested manifests, lock files, and versions.tf files appear absent.

Use the assessor proportional-score helper.

Replace the direct ratio calculation with calculate_proportional_score() while preserving the 35-point fallback.

As per coding guidelines, “Use calculate_proportional_score() for proportional scoring in assessors.”

@gurnben Thank you for this contribution, and apologies for how long it sat. Since the only CI failure was formatting and you may not be watching this repo anymore, I used maintainer edit access to get it over the line rather than let the stale bot close it. Your commit and authorship are preserved; I pushed a rebase plus one follow-up commit:

  • Rebased onto current main (233 commits). The main conflict: main independently gained a go.sum-only subdirectory search in May (5900184). I resolved it by keeping your more general _rglob_filtered recursive fallback, which covers all lock file types and excludes vendor/, node_modules/, .venv/, .git/, and .terraform/.
  • Ran black and isort to fix the CI failure.
  • Synced docs/attributes.md with the new behavior (subdirectory search, Terraform fallback scoring, not_applicable for manifest-less repos), per our docs convention.

I also re-validated against real repos: ocm-api-model passes via sub-module go.sum files, rosa-external-tests now returns not_applicable instead of failing, and terraform-aws-modules/terraform-aws-vpc scores 35 with accurate constraint evidence instead of 0 with a misleading "no lock files" message.

CI is now green across the board, so I'm merging. Thanks again for the thorough fix and the audit that motivated it.
