guidelines: change the coverageThreshold object's line and function values from
70 to 80 (e.g., coverageThreshold = { line = 80, function = 80, statement = 70

Workflow dispatch lacks required actions: write permission
Medium Severity
The newly added gh workflow run call in tag-extension.mjs requires the GITHUB_TOKEN to have actions: write permission to invoke the workflow dispatch API. However, the release.yml workflow only declares contents: write, pull-requests: write, and id-token: write — the actions permission is absent. This means the gh workflow run call will always fail silently, and since tag pushes from GITHUB_TOKEN also don't trigger workflows, the extension release will never be auto-triggered.

"test:unit", "test:integration", "test:e2e", and "test:ci" entries under the

missing scripts "test:coverage", "test:unit", "test:integration", "test:e2e",

enforcement and CI runs are possible. Implement "test:coverage" to run the test
runner with coverage enabled and thresholds enforced, "test:unit" to run unit
tests, "test:integration" and "test:e2e" to target their respective test suites
(using the same test runner with appropriate patterns), and "test:ci" to run the
full CI pipeline (coverage + fail-on-threshold + no watch). Ensure script names
exactly match "test", "test:watch", "test:coverage", "test:unit",

Extension release failures are silently ignored

When gh workflow run fails, tag-extension.mjs only logs a warning and continues. Since tag pushes created by GITHUB_TOKEN do not trigger workflows, this can complete release.mjs successfully while skipping extension-release.yml, leaving the extension unpublished with no failing CI signal.

Extension publish failure is silently ignored
Medium Severity
tag-extension.mjs treats gh workflow run extension-release.yml failures as non-critical, so bun run release can succeed even when the extension release never starts. Because dispatch only runs when createAndPushTag returns true, a later rerun skips dispatch once the tag already exists, leaving that version unpublished.

CI no longer enforces lockfile consistency
Medium Severity
Replacing npm ci with plain bun install removes strict lockfile validation in CI. bun install can regenerate bun.lock instead of failing when manifests and lockfile diverge, so workflows may pass with dependency states that are not actually committed.

Remove || true to fail fast on lockfile mismatches during releases.
Using || true masks real errors from bun install --frozen-lockfile after version updates. If this command fails—due to lockfile inconsistencies, dependency resolution issues, or toolchain problems—the release should stop, not silently proceed. Bun is properly available in CI, so any failure here is a legitimate problem to fix before publishing.

- Replace `npx` with `bunx` for running scripts in various workflows. - Update CI configurations to utilize Bun for dependency installation and script execution. - Modify release and extension workflows to trigger builds and packaging using Bun. - Ensure consistent environment variable usage for Bun and Node versions across workflows.

CI tests silently drop coverage collection
Medium Severity
The CI test command changed from npm run test:coverage (which generated coverage data with explicit thresholds) to bun run turbo:test, which runs each package's test script — all of which now specify --coverage=false. This silently stops collecting coverage in CI, while the Upload Test Results step still references a coverage directory that will never be generated. A test:ci script exists in root package.json (running turbo test:ci) and in apps/cli and apps/mcp, specifically designed for CI with --coverage enabled, but it's not being used.
