What

On a first install, install.sh mentions a GitHub star with a link. This lets the installer give that star when the user says so, and brings the same mention to install.ps1, which had none.

  • The installer reads whether the account the gh CLI is signed in to has starred the repository (gh api --include user/starred/devswha/herdr-web-ui), by the HTTP status GitHub answers with.
    • 204, already starred: it says nothing.
    • 404, not starred, at a terminal: it prints the link and asks once, star it now with the GitHub account gh is signed in to? [y/N]. Only y or yes stars (PUT user/starred/…). Enter, n or anything else does nothing.
    • No gh, no sign-in, any other status, no answer from gh, or no terminal: the link line as before, and no question.
  • It never stars without that answer.
    • No terminal (a script, a pipe) or CI set: nothing is asked. install.sh asks only when stdout is a terminal and /dev/tty opens, install.ps1 only when neither console input nor output is redirected.
    • A terminal with nobody at it (an agent's pty, an unattended docker exec -t): the question waits 20 seconds and goes on without a star. install.sh reads the answer with bash's read -t (POSIX read cannot give up; without bash it does not ask), install.ps1 waits for a first key.
    • What was typed before the question is discarded, so that it is not taken for the answer (install.sh needs perl for this; without it the typed-ahead line is read).
  • gh gets 10 seconds for each call, so a gh that hangs does not hold up an install that is done.
  • A rerun stays quiet, as before, and does not call gh.
  • In install.sh the block moves to the end, after the PATH advice, so that leaving the question loses none of the output above it. Ctrl-C at the question ends the script with status 0.
  • Nothing in the block can fail an install that is already done: a gh that refuses the star is said in one line.

Checks

  • New scripts/install-star.test.ts (unit suite): the whole install.sh, run as curl … | sh runs it, on a PATH that holds only what it needs, with stand-ins for herdr, node and gh. Without a terminal: no gh, starred, not starred, a rerun, a gh that hangs. At a terminal (script(1), Linux): y, Enter, n, yy, end of input, typed-ahead y, Ctrl-C, a refused star, a 403, a 500 whose text names a 404, no sign-in, CI set, and nobody answering. The file takes about 20 seconds, which is the question's own wait; its tests run side by side.
  • Each fix taken out of install.sh in turn (the INT trap, the typed-ahead discard, the CI check, the status match) makes the test for it fail.
  • scripts/windows-install.test.ps1: gh is a stand-in gh.cmd first on PATH, run as a real process, so native stderr and exit codes cross the same boundary as in an install. It covers starred, no sign-in, a rerun with a caller's $newInstall set, a gh that hangs, CI set, and, with the installer's own text and its two terminal answers given, every answer to the question. It passes under Windows PowerShell 5.1 in CI's "Native Windows install" job.
  • "Real Windows install" (this commit on a clean Windows runner) passes.
  • shellcheck install.sh is clean.
  • ONE_LINE=1 bun scripts/fresh-install-docker.ts devswha/herdr-web-ui v0.3.52 (a bare Ubuntu, no gh) passes with the final install.sh: the link line is the last line of the first install, and the reruns stay quiet about it.
  • A Codex adversarial review (gpt-6.1-sol, xhigh) found six issues; all six are fixed in cb87114.
  • A second Codex pass at 3700e6d (the merge session) found one High and six Medium: a y typed before the question was taken for its answer on a PC without perl or when the flush failed; the question went to stdout while the answer came from /dev/tty; a background job reaching for the terminal was stopped by it; the gh watcher sent only TERM and outlived a quick call; on Windows a first key was followed by an unbounded Read-Host, gh's output completion was outside the deadline with no disposal, and the test's gh.cmd stand-in could not run through Process.Start. Fixed in eaf9cdf (Unix) and 40b4d6b (Windows), each with tests that fail on the code before them: a PC without perl with y typed ahead, a background job under a shell with job control, a gh that ignores TERM, the 20 seconds measured from the question itself; on Windows the answer is read key by key within one deadline, the shim runs through cmd.exe, and the test asserts the status read happened.
  • A third pass on the delta 3700e6d..73afcb8: the High and five Medium are closed, the watcher cleanup is narrowed to Low (its sleep 1 is briefly orphaned after a quick call; it identifies gh by PID), and one Medium stays for a follow-up, install.ps1: a shim gh's child that keeps the output pipe can outlive the 10-second deadline #558: a .cmd shim's child that keeps the stdout pipe can outlive the deadline, and the readers are not closed by Dispose on .NET Framework. The official gh.exe is not a shim.
  • CodeRabbit on the fixes: the Unix status read went through a pipe into sed, which a child gh left holding its output would hold past the deadline; it goes through a file now, read once gh_api has returned, with a stand-in mode and a test for it.

Not covered

  • A real gh giving a real star was not exercised: every run used a stand-in. The status lines the code tells apart (204, 404, none without a sign-in) were read from the real gh 2.63.2.
  • On Windows, whether the console check and the 20-second key-by-key answer behave at a real console was not exercised: CI has no console, so the test gives those two answers itself.
  • macOS: /bin/sh there is bash 3.2, which has read -t; the terminal tests run on Linux only.
  • Marketplace installs (herdr plugin install) do not run either installer and see none of this.

On a first install, install.sh mentioned a GitHub star with a link. When the gh CLI is signed in,
it can now give that star: it reads whether the account has starred the repository, says nothing
if it has, and otherwise asks once at the terminal and stars only on "y". Without gh, without a
sign-in or without a terminal (an agent, a script, CI) it prints the link as before and asks
nothing. The block moves to the end of the script, so that a question left unanswered loses none
of the output above it.

install.ps1 gets the same mention and question; it had neither.

📝 Summary

Summary by CodeRabbit

  • New Features
    • On a first install, the installer may offer to star the repository if GitHub CLI confirms the signed-in account has not already starred it. The repository is starred only after confirmation.
    • The prompt appears only in an interactive terminal and times out after 20 seconds. If the account has already starred the repository, or the check is unavailable, no prompt is shown. Checking or starring failures do not interrupt installation.
  • Documentation
    • Updated installation guidance to explain the optional star prompt and when it appears.

Walkthrough

Both installers check GitHub star status after a new install. They prompt only when GitHub confirms that the account has not starred the repository and an interactive terminal is available. They submit a star only after an affirmative response. Tests and documentation cover this behavior.

Changes

Installer star prompt

Layer / File(s) Summary
Check star status and handle the prompt
install.sh, install.ps1
Both installers add bounded GitHub API checks and interactive prompts. They submit a star only after an affirmative response.
Gate the offer on a new install
install.sh, install.ps1, CHANGELOG.md, INSTALL.md, docs/guide.md
The installers run the star check only after a new install. Documentation describes eligibility, terminal prompting, and timeout behavior.
Test prompt conditions and outcomes
scripts/install-star.test.ts, scripts/windows-install.test.ps1
Tests simulate GitHub responses, terminal input, timeouts, CI, reruns, and failures. They check prompt eligibility, star requests, and installation outcomes.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 73afc

A first-time shell install can remain stuck at the optional star check if gh leaves a child holding its output open. Bound the capture before merging, or accept this narrow risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 73afc

The new action is limited to starring one repository and requires explicit confirmation. Failure normally leaves the completed installation intact. The shell timeout has a narrow process-containment gap: a surviving child process could keep the optional status check waiting.

Retained concerns

  • Low · reliability · inferred: The new shell status check is not fully bounded for helper process trees. Its watcher terminates only the direct gh PID; a surviving descendant holding stdout open could keep the capture pipeline waiting after that PID exits. This weakens containment of an optional authenticated helper operation, although production reachability of this failure mode is unverified.
Security review details

Security Blast Radius

  • observed — The added API requests target only user/starred/devswha/herdr-web-ui on github.com. The write changes the authenticated account's star relationship with that repository; these added calls do not accept a user-selected repository or hostname.

Trust Boundaries and Controls

  • observed — The shell reads confirmation from its foreground controlling terminal, flushes queued input, rejects unavailable prerequisites, and limits the read to 20 seconds. PowerShell rejects redirected input/output and CI, flushes queued input, and accepts only a completed affirmative line within its deadline. Nonaffirmative or unavailable input does not authorize PUT.
  • observed — Prompt eligibility is separate from the authenticated status read: both installers can perform that read on first installation without an interactive terminal. Only the subsequent write requires affirmative terminal input.

Resilience and Maintainability Implications

  • inferred — Cleanup of the direct shell helper does not guarantee cleanup of inherited output handles. A descendant retaining stdout can defeat bounded completion of the status capture, although the installation has already completed and no resulting security-boundary bypass is established.

Hardening Proposals

  • proposed — Extend shell timeout containment to the helper's process tree and output capture, using isolation that cannot signal the invoking terminal's process group. Exercise a descendant that retains stdout to validate bounded completion.

From an adversarial review of the star step:

- A terminal does not mean somebody is at it (an agent's pty, an unattended docker exec -t). The
  question now waits 20 seconds and goes on without a star; it is not asked when CI is set.
  install.sh reads the answer with bash's read -t, install.ps1 waits for a first key.
- gh gets 10 seconds for each call. A gh that hangs no longer holds up an install that is done.
- "Not starred" is GitHub's 404 status, read from `gh api --include`, not the text of an error.
- Ctrl-C at the question ends install.sh with status 0: the install was done.
- What was typed before the question is discarded, so that it is not taken for the answer.
- install.ps1 sets $newInstall itself; a caller's variable or strict mode cannot reach it.

scripts/install-star.test.ts runs install.sh whole, as `curl | sh` does, on a PATH of stand-ins,
with and without a terminal. scripts/windows-install.test.ps1 runs gh as a stand-in process.

170-172: 🩺 Stability & Availability

The alleged 15-second pipe wait cannot cause this assertion to fail: when WaitForExit(10000) times out, Invoke-GhApi kills the process and returns before accessing $said.Result. The orphaned ping therefore does not make this installer call wait for the pipe. The comment’s proposed PowerShell 5.1 confirmation is not supported by the stated failure mechanism.

install.ps1-134-141 (1)

134-141: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Close the PowerShell pipes or abandoning gh can still block the installer.

WaitForExit(10000) waits only for the process. $said.Result blocks until stdout reaches EOF. If gh exits but a child process it spawned still holds the inherited stdout handle, .Result blocks with no time limit. This is less likely than the hang case, but the 10-second guarantee does not cover it. The timeout path also has a gap. It kills only gh, not its process tree. If Kill() throws, the catch { } hides that error. Before the code reads .Result, wait on the task with a time limit.

Proposed fix
-    if ($said.Result -match '^HTTP\S* (\d{3})') { $status = $Matches[1] }
+    if (-not $said.Wait(2000)) { return }
+    if ($said.Result -match '^HTTP\S* (\d{3})') { $status = $Matches[1] }

… and a gh that hangs is killed

The question was asked wherever a terminal opened, after a flush that
was optional: on a PC without perl, or when the flush failed, a "y"
typed before the question answered it, and a background job that
reached for the terminal was stopped by it with no 20 seconds to end
that. Now perl is required for the question, one perl call checks the
install is in the terminal's foreground group and empties what was
typed, and either failing means no question. The question itself is
written to the terminal it is read from, not to stdout.

gh's 10 seconds were a single TERM from a watcher that outlived a quick
call: the watcher now looks once a second and is reaped, and a gh that
ignores TERM is killed two seconds later.

Tests: a PC without perl with y typed ahead, a background job under a
shell with job control, a gh that ignores TERM; the "nobody there"
case measures the 20 seconds from the question itself. Each failed on
the code before this (Codex findings 1, 2, 4, 5 and the Low).

…seconds, and a shim gh runs

Read-Host after a first key waited without end for the Enter: the
answer is now read key by key within 20 seconds in all, and a line left
unfinished is no answer. gh's deadline covers its output as well as its
exit (a child it handed the output to could live on), what outlasts it
is killed with its children, and the process is disposed. A gh that is
a .cmd or .bat shim runs through the command interpreter, so the test's
stand-in reaches the installer's own launcher; the test now also
asserts that the status read happened (Codex findings 3, 6, 7).

…its output

The status came through a pipe into sed: a gh that left a child holding
its output would hold the pipe's reader past the deadline, and the
install with it. The answer goes to a file now, read once gh_api has
returned; a child that lives on keeps a descriptor to a removed file.
The test's stand-in has a mode that leaves such a child (CodeRabbit).

Fast checks on d0b6a1a: cause and fix (from the session that built this PR; nothing pushed by it since 3700e6d)

The failure is scripts/install-star.test.ts:248, "ends well, with no star, when the question is left with Ctrl-C": expected exit 0, received 130 (run).

Cause. offer_star in install.sh writes the question and only then sets the INT trap. The test presses Ctrl-C as soon as the question is on the terminal; when that lands before trap 'echo; exit 0' INT has run, sh dies of SIGINT. The order is the same as in the first version of this PR, so the window is not from the later commits; it had only never lost the race in CI.

Evidence (local, on d0b6a1a, nothing committed):

install.sh Ctrl-C test
unchanged 0 of 40 runs fail
sleep 0.5 between the printf and the trap 5 of 5 fail with Received: 130
trap set before the question, the same sleep 0.5 after the question 5 of 5 pass

Fix. Set the trap first, and drop it again when the question cannot be written:

  # the install is done: leaving the question with Ctrl-C is an answer, not a failure
  trap 'echo; exit 0' INT
  printf '%s' "herdr web ui: star it now with the GitHub account gh is signed in to? [y/N] " >/dev/tty 2>/dev/null || { trap - INT; return 0; }

The existing Ctrl-C test covers it, so no test change is needed, and install.ps1 has no such trap to mirror. A rerun of the failed job would most likely pass without this, but the race would stay in the installer.

A Ctrl-C the moment the question appeared, before the trap was set,
ended the script with 130; the harness pressing it as soon as the
question is on the terminal found that window in CI once the question
went to /dev/tty directly.

## Change

Prepares v0.4.0 and remote bundle 20.

- `package.json` and `herdr-plugin.toml`: 0.3.52 → 0.4.0. A minor bump: the chat's Send/Stop and queued follow-ups (#520), the sidebar redesign (#521, #556, #557, #559), the mobile key bar editor (#508), Settings one page at a time (#562), release notes before and after an update (#535, #560) and the installer's star offer (#550) change how the app is used.
- `shared/machines.ts`: `REMOTE_BUNDLE_VERSION` 19 → 20. #520, #508, #525 and #537 changed `server/`, so remote PCs need a new bridge; until a PC updates, Send during work keeps the draft and asks for the update.
- `CHANGELOG.md`: the Unreleased notes become `[0.4.0] - 2026-10-08`, with the compare links; two stray blank lines inside the section removed; the #521 entry says a red question mark (#557), and the #535 and #560 entries say Settings → About (#562).
- `release-summaries.json`: the first entry, 0.4.0 in English, Korean, Japanese and Chinese, seven lines under each of New features, Improvements and Bug fixes, which `Settings → About` and the header line show before and after the update installs.

## After the merge

1. `git tag remote-v20 <merge commit> && git push origin remote-v20` → the remote-bundles workflow publishes the five bundles and `manifest.json` as release `remote-v20`.
2. Only then `gh workflow run release.yml --ref main -f version=0.4.0`: preflight validates version, notes and summaries, CI runs on the exact commit, and the tag `v0.4.0` with its GitHub release is created.

## Validation

- `bun scripts/release-notes.ts 0.4.0` prints the notes (version sources agree, one heading, summaries in all four languages).
- `server/release-notes.test.ts` (this repository's summaries: every release since 0.3.52 told in four languages, lines ≤ 90 characters, the same lists in every language) and `scripts/release-notes.test.ts` pass.
