AI-3573 (partial; no GitHub issue — filed in Linear directly)

What & why

Setup ticked through two states where recording silently does nothing: Codex hooks that have not been trusted, and a git older than 2.54, which ignores the commit config hook. Setup now reminds the user to trust the Codex hooks whenever it installs them, and reads git --version to warn instead of ticking the git hook when git is too old.

Where to look

This is the CLI half of AI-3573. Keeping the browser Done screen's capture list visible (kcap-server) and per-agent recording state in kcap status are still open on the issue.

Verification

GitHookInstallerTests 11/11 (new parse cases cover Apple and Git for Windows version strings); SetupCommandTests 104/104.

🤖 Generated with Claude Code

Summary by CodeRabbit

  • Bug Fixes
    • Setup now warns when Git is older than 2.54 and does not enable the commit-filing hook. Until Git is upgraded, commits are filed from agent shell commands.
  • Documentation
    • Setup help clarifies that installed Codex hooks remain inactive until trusted and that setup provides a reminder when it installs them.

Both fail silently after a green setup: untrusted Codex hooks never fire, and
git before 2.54 ignores the config hook.

📝 Walkthrough

Walkthrough

Setup now checks the installed Git version before reporting commit-hook installation. It warns when Git is older than 2.54. Setup also displays a Codex trust reminder when Codex hooks were installed.

Changes

Git hook setup

Layer / File(s) Summary
Git version detection and parsing
src/Capacitor.Cli/GitHookInstaller.cs, test/Capacitor.Cli.Tests.Unit/GitHookInstallerTests.cs
Adds Git 2.54 as the minimum version and helpers to retrieve and parse Git version output. Git command execution now receives a complete argument list. Tests cover vendor-suffixed, plain, and invalid version output.
Setup messages and guidance
src/Capacitor.Cli/Commands/SetupCommand.cs, src/Capacitor.Cli.Core/Resources/help-setup.txt, README.md, test/Capacitor.Cli.Tests.Unit/Commands/SetupCommandTests.cs
Setup warns when the detected Git version is below 2.54. Otherwise, it reports hook installation, including when the version is unknown. Setup displays a Codex trust reminder when Codex hooks were installed. Help and README text describe this behavior.

Merge Risk: 🔵 Low · up to 01a0e

Setup may show recording as successful when Git support is unknown, and its old-Git guidance should clarify that the installed entry remains in place. These are bounded setup and documentation risks to address before users rely on the status.

Warn during setup about inactive Codex and Git hooks

🐞 Bug fix 📝 Documentation 🧪 Tests 🕐 20-40 Minutes

Grey Divider

AI Description

• Warn when installed Codex hooks still need user trust before recording can begin.
• Warn instead of showing a success tick when Git is too old to run the installed hook.
• Document both caveats and test version parsing and setup messages.

High-Level Assessment

Keep the hook installed and make its limitations visible during setup. Blocking installation on older Git would remove a configuration that can work after an upgrade; the existing shell-command fallback remains available.

Remediation recommended

1. Unverified Git hooks get a success tick 🐞 Bug ≡ Correctness
Description
GitHookLine treats a null version as confirmation that every commit will be filed under its agent
session. If git --version fails or returns unreadable output after hook installation, setup prints
the green success line even though it cannot tell whether the installed Git is older than 2.54.

Fail-closed messaging matches accepted precedents for unavailable values and prevents a misleading
setup success tick.

Evidence
The installer returns null when the version command fails or its output cannot be parsed; setup
passes that result directly to a formatter whose only warning branch requires a non-null version
below the minimum.

2. Malformed Git output can abort setup 🐞 Bug ☼ Reliability
Description
ParseGitVersion passes parsed major and minor integers directly to new Version without checking
that they are nonnegative. If a Git executable reports a string such as git version -1.54, the
constructor throws during setup's new version check rather than returning an unreadable-version
result.

Fixed in #1372 (fa0f409): components are parsed with NumberStyles.None, so a sign is rejected and the parser returns null. Added the -1.54 and 2.-1 cases.

Folded into #1372 so the three setup changes land as one PR (they edit the same lines of SetupCommand). Review comments here are addressed there.
