feat(agent): install and verify Claude Code lifecycle hooks - #94
Settings → Automation installs, verifies, repairs and removes Dilated’s Claude Code hooks. Installation preserves unrelated settings, hooks and symlinked settings files, backs up existing files and refuses invalid JSON. Health reports missing, installed or drifted hooks.
Prompts start a hold and tool hooks renew it. Completion releases it, and Dilated’s Stop blocks later hooks until Resume. Automatic renewal lasts up to one hour after the last prompt or tool hook. Claude omits Stop on user interruption, so an interrupted hold can last up to 70 minutes including its final lease. The UI and docs disclose this limit. Quiet turns beyond an hour need an explicit timed hold.
Validation: full coverage-enabled verification passes with 651 Swift tests, 105 release tests, 16 bundle checks and 42 website tests; scoped Qlty passes. Red/green regressions cover unrelated-command preservation, interrupted-turn expiry, renewer restart and disabled-hook refusal. Process tests check active-hold release and Stop safety. Earlier isolated Claude Code and rendered Settings checks passed; live Claude settings were not changed.
This targets the next release. Published beta.11 is unchanged.

Walkthrough
The change adds Claude Code hook installation and management, maps supported hook events to agent lifecycle commands, and exposes hook health and actions in automation settings. Hook execution runs quietly, and hook-created holds receive a distinct label.

Summary
Hook configuration and input contract Sources/DilatedControl/ClaudeHooks.swift, Tests/DilatedControlTests/AgentHooksTests.swift, docs/AUTOMATION.md
Installation checks five supported events, preserves unrelated settings, backs up changed settings, and reports missing, installed, or drifted health. Input parsing validates JSON and maps supported events to begin, renew, or end commands. Tests cover installation, repair, removal, invalid settings, symlinks, and input validation. Documentation describes hook setup and lifecycle behavior.
The CLI reads hook input from standard input and runs the parsed command without output. Hook-decided commands only retry app launch for begin commands. Hook-created holds use a distinct label and a one-hour renewal deadline, which successful hook activity extends. Tests cover lifecycle behavior, renewer timing, and subprocess execution.
Automation settings display hook health and provide install, verify, repair, and remove actions. The view refreshes health on appearance and app activation. UI tests cover rendering and installation.

A resumed Claude turn can lose its hold early, and repairing disabled hooks can report success without enabling them. Address both before release; their limited triggers do not otherwise block merge.

Explanation
The title "feat(agent): install and verify Claude Code lifecycle hooks" matches the main change in the changeset. The PR adds a ClaudeHookInstallation type with install, remove, and health checks, a Settings UI for these actions, and the hook-driven lease handling in AgentLifecycle and AgentRenewer. The title names the primary feature, and the test and docs changes support it. It is specific and uses a conventional commit prefix.

Review the Claude-hook installation and health checks against dev/m2 at 7860ef6. This is a single-user local macOS app. Check preservation of existing Claude settings/hooks, shell quoting, hook lifecycle and Stop safety. The prior request was rate limited and no review has completed. Beta.11 is already tagged and published; this PR belongs to the next release.
The process test removes the hold with stopAll before it invokes the installed Stop hook. The Stop assertion therefore does not prove that the hook releases an active hold. Invoke Stop immediately after the PreToolUse check and assert that app.labels is empty. Keep the later stopAll sequence to test that stopped hooks cannot create a new hold.

- Line 142: Add cleanup for the PID-based renewer started by ensureRenewer after
a user-interrupted turn, or bound its lifetime while preserving awake holds for
supported turns longer than ten minutes. Use an interrupt signal with a verified
Claude Code contract; do not assume Stop, StopFailure, SessionEnd, Notification,
or idle_prompt reliably signals interruption.
- Around line 30-46: Update `owns(_:)` to recognize only generated
command-shaped hooks: require the command type, an `exec '` prefix, and a suffix
consisting of `Self.marker` followed by `"$PPID"`. Do not include the app path
in the ownership check, so generated hooks from older paths remain identifiable
while user commands containing only the marker are preserved.

Fix-check pass 2: 5df15dd addresses both findings and strengthens the active Stop regression. The one-hour quiet renewal window supports turns longer than ten minutes and bounds interrupted holds without assuming an interrupt event. Full coverage verification and scoped Qlty pass. Single-user local macOS app; keep review within this hook slice.

Reviewed 5df15dd and the red/green evidence for command preservation and bounded hook renewal. Only real hook events extend the one-hour window; generic PID renewal keeps its existing behavior. The Stop process regression now releases a live hold. Full coverage verification and scoped Qlty pass. Keep CI and the CodeRabbit fix-check gates before merge.

Report repair failure while Claude settings disable hooks.
install() keeps the user's disableAllHooks: true value. Claude does not run the installed hooks while that value is set. health() still returns .drifted after the write. The UI nevertheless reports "Installed Claude Code hooks. Restart existing Claude sessions to load them." That message is false for this state.
Keep the user setting unchanged. Make install stop before it writes when the setting is true. The error then appears in the Settings detail text. Remove stays available.

Final pass 3 on c9b7d57. Both pass-2 findings have red/green regressions: tool hooks restart an expired renewer using a validated PID, and disabled settings refuse installation/repair without writes while removal stays available. Full coverage verification passes with 651 Swift tests, 105 release tests, 16 bundle checks and 42 website tests; scoped Qlty passes. Single-user local desktop threat model. Keep the review within the existing hook slice; remaining nonblocking findings after this pass go into one roadmap follow-up.

Rechecked c9b7d57 and the two new red/green regressions. Hook renewal validates and carries the Claude PID, then restarts the renewer after a successful renewal. Disabled settings refuse repair without writes; removal preserves the setting. Full local coverage verification and scoped Qlty pass. Keep the final review and CI gates before merge.

Settings → Automation installs, verifies, repairs and removes Dilated’s Claude Code hooks. Installation preserves unrelated settings, hooks and symlinked settings files, backs up existing files and refuses invalid JSON. Health reports missing, installed or drifted hooks.
Prompts start a hold and tool hooks renew it. Completion releases it, and Dilated’s Stop blocks later hooks until Resume. Automatic renewal lasts up to one hour after the last prompt or tool hook. Claude omits Stop on user interruption, so an interrupted hold can last up to 70 minutes including its final lease. The UI and docs disclose this limit. Quiet turns beyond an hour need an explicit timed hold.
Validation: full coverage-enabled verification passes with 651 Swift tests, 105 release tests, 16 bundle checks and 42 website tests; scoped Qlty passes. Red/green regressions cover unrelated-command preservation, interrupted-turn expiry, renewer restart and disabled-hook refusal. Process tests check active-hold release and Stop safety. Earlier isolated Claude Code and rendered Settings checks passed; live Claude settings were not changed.
This targets the next release. Published beta.11 is unchanged.
