User description

Closes #1541

Implemented by dev-lead agent. Please review.


CodeAnt-AI Description

Prevent redundant vendored copies of tools already installed by CI

What Changed

  • CI now detects committed copies of supported tools under dependency directories when the same tools are installed by package managers.
  • The check reports the tool and conflicting vendored path, then fails with guidance to remove the redundant copy.
  • Legitimate first-party files, standalone vendored tools without a matching CI install, and local ignored dependencies do not trigger the check.
  • Added coverage for clean trees, detected conflicts, allowed cases, and invalid paths.

Impact

✅ Fewer duplicate tool installations in CI
✅ Clearer errors for redundant vendored tools
✅ Prevents accidental commits of CI-installed dependencies

📝 Walkthrough

Walkthrough

The change adds a Bash guard that detects tools installed by CI package-manager steps and also vendored under dependency directories. Bats tests cover detection, exclusions, clean trees, and invalid paths. The lint workflow runs the new tests.

Changes

Vendored tool overlap guard

Layer / File(s) Summary
Implement vendored tool overlap detection
scripts/check-vendored-installed-tools.sh
The guard reads allowlisted CI install steps, scans dependency-manager directories, reports overlaps, and returns defined exit statuses.
Validate and run the guard
tests/test_vendored_installed_tools.bats, .github/workflows/lint.yml
Bats tests cover clean trees, detected overlaps, exclusions, and nonexistent trees. The lint workflow runs the test file.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to dce2e

This PR adds a CI guard for redundant vendored tools, but its workflow parsing may occasionally flag unrelated text or miss multiline installation commands, and the policy can be silently disabled if its test file is removed or renamed. The change is mergeable with explicit owner awareness and follow-up for these bounded risks.

Code Review

This pull request introduces a new guard script, check-vendored-installed-tools.sh, along with corresponding BATS tests, to prevent committing vendored copies of tools that are already installed by CI workflows. The feedback highlights several improvement opportunities: ensuring list_tree_files correctly identifies the git root when run inside temporary directories, replacing non-POSIX \b word boundaries in regular expressions for better portability, simplifying redundant flags in grep, and using synthetic workflow files in tests to avoid dependency on the real lint.yml file.

Review mode: triage-approved (single reviewer)

Summary

Adds scripts/check-vendored-installed-tools.sh (131 lines), a narrow guard that fails CI when a tool CI already installs via a package manager (apt-get/npm/pip; allowlist: bats, yq, markdownlint-cli2) is also committed as a vendored copy under node_modules/, vendor/, or .venv/. Includes 7 bats tests covering the #1449 fixture, narrowness/no-false-positive cases, line-continuation installs, and invalid-tree usage; wired into lint.yml's existing run-bats.sh invocation (one-line change). Triage assessment confirmed: scope is exactly the enforceable sliver described in #1541.

Linked issue analysis

Closes #1541. All 4 acceptance criteria are substantively addressed: (1) guard fails when a CI-installed tool is also vendored under a dependency-manager directory; (2) deliberately narrow — static allowlist plus actual-install-step overlap, verified by no-false-positive tests (vendored-without-install, first-party asset outside dep dirs, install-without-vendored); (3) the #1449 node_modules/bats-alongside-apt-get fixture fails and the current clean tree passes; (4) wired into lint.yml alongside the existing bats suite. Matches the issue's Dev Notes: simple static tuples, no general dependency resolver.

Findings

No blocking findings. Prior bot review findings were all addressed and their threads resolved: multiline install steps are handled by folding shell line-continuations before matching (codeant-ai Major); GNU-only \b word boundaries were replaced with POSIX ERE classes (gemini medium); git-work-tree detection checks for $TREE/.git directly so nested non-git fixture trees fall back to a filesystem walk (gemini high). Script uses set -euo pipefail, no eval/injection surface, shellcheck passes. Secret-scanning MCP tool unavailable in this environment; gitleaks CI check passed. Workflow change is a single test-file addition to an existing run-bats.sh list — no Actions security smells.

CI status

All substantive checks green: shellcheck, bats, unit-tests, Lint, gitleaks secret scan, CodeQL (actions + python), SonarCloud quality gate, agent-shield, actionlint, and all repo guard checks. Cancelled entries in the rollup are superseded dev-lead/concurrency runs on earlier commits; the latest review and Dismiss runs succeeded. CodeRabbit approved; all review threads resolved; no unanswered human-reviewer questions.

Review mode: triage-approved (single reviewer)

Summary

Adds a narrow bats guard (scripts/check-vendored-installed-tools.sh + 7-test bats suite) that fails CI when a tool already installed by a workflow package-manager step (apt-get/npm/pip) is also committed as a vendored copy under node_modules/, vendor/, or .venv/ — the exact #1449 failure signature. Wired into lint.yml via a one-line addition to the existing run-bats.sh list. Script is defensive (set -euo pipefail, POSIX ERE word boundaries, git-tracked-files scan with filesystem fallback for fixture trees, line-continuation folding) and all six bot review findings were fixed and resolved.

Linked issue analysis

Closes #1541 ([Phase 4] Bats guard: vendored copy of a CI-installed tool, split from #1468 AC 3). All four acceptance criteria are substantively addressed: (1) install-step tool extraction from .github/workflows/** including installs split across shell line-continuations; (2) narrow scoping — fires only on the CI-installs-X AND vendored-copy-of-X overlap, with tests proving first-party assets and unmatched vendored dirs pass; (3) the #1449 node_modules/bats fixture fails red and the current clean tree passes green; (4) wired into lint.yml alongside the existing bats suite.

Findings

No blocking findings. All six prior bot review threads (codeant-ai, gemini-code-assist, coderabbitai) are resolved with verified fixes in the current head: multiline install detection via awk continuation-folding, .git-presence gating for nested temp trees, POSIX ERE word boundaries replacing GNU-only \b, removal of the redundant grep flag, and self-contained synthetic test fixtures. No security anti-patterns; the lint.yml change adds no new actions, permissions, or untrusted input. MCP secret-scanning tool unavailable in this session; the gitleaks CI check passed.

CI status

All current checks green: shellcheck/ShellCheck, bats, unit-tests, Lint, CodeQL (actions + python), Agent Security Scan, agent-shield, Secret scan (gitleaks), SonarCloud, actionlint, and all org guard checks pass at the reviewed commit. Cancelled entries in the rollup are superseded earlier runs.
