console.log put the notice on stdout, so any non-JSON command (e.g. spec show, change show) had it prepended to raw/passthrough output on a fresh machine with no prior telemetry config — breaking pipes and consumers expecting exact file content. --json mode already avoided this by deferring the notice; stderr fixes it for every mode at the source instead of special-casing each one.
📝 WalkthroughWalkthroughChangesTelemetry notice routing
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to The notice is moved to stderr so command output remains parseable, but the tests do not currently verify that stdout stays clean in all relevant paths. The PR is mergeable with explicit owner follow-up to add those assertions. Possibly related PRs

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep an explicit stdout assertion.
The fixture now spies only on console.error. The tests can pass if maybeShowTelemetryNotice() writes to both console.error and console.log, so they no longer prove that stdout remains clean. Keep a console.log spy and assert that it is not called in the disabled, first-run, repeat, and silent/deferred cases.
Run pnpm exec vitest run test/telemetry/index.test.ts after adding these assertions. This protects the stdout contract in the PR objective. As per coding guidelines, use the focused Vitest command above.

Summary
maybeShowTelemetryNotice()printed the first-run notice withconsole.log, so it landed on stdout. On any machine with no prior global telemetry config (fresh clone, new container, new dev laptop), the first non-JSON command that prints raw content gets the notice prepended to its output.Reproduction on
maintoday:The redirected file starts with the notice instead of the spec. Anything piping or parsing that output gets corrupted content.
Why CI never caught this: telemetry is disabled whenever
CIis set (isCiEnvironment), so the notice never fires in GitHub Actions. Verified both ways againstmain:test/commands/spec.test.tsCI=true(GitHub Actions)CI, clean config (real user machine)spec show > should display spec in text formatSo
maincurrently fails its own test suite for a contributor cloning fresh, while CI stays green.--jsonmode was already special-cased to defer the notice (#1609, #742) precisely because it broke JSON parsers — but the same stdout-pollution exists for every other stdout-producing command and wasn't covered.Fix
Move the notice to
console.error(stderr). Stdout stays reserved for command output in every mode, rather than special-casing one command shape at a time. Existing--jsondefer behavior (silentoption,noticeSeenpersistence) is untouched.Test plan
pnpm test— 136/136 files, 3969/3969 tests pass (135/136 before the fix, on a machine with no prior telemetry config)pnpm lint— cleanpnpm build— cleantest/telemetry/index.test.tsto spy onconsole.errorinstead ofconsole.log, matching the new streamXDG_CONFIG_HOME: after the fix,openspec spec show auth > auth.mdwrites only spec content, and the notice still reaches the user on stderrNo changeset added — per
.changeset/README.md, routine bug fixes follow the normal release cadence unless a maintainer wants dedicated release tracking. Happy to add one on request.
