Add Codex hook controls, an OpenCode plugin installer and editable CPU fallback presets for CLI agents.

Codex uses the documented prompt, tool, Stop, Interrupt and SessionEnd hooks. Settings says when configuration is installed and tells users to review and trust it in Codex. It leaves feature flags, managed policy and trust unchanged. The OpenCode plugin uses the documented busy/idle lifecycle, serializes calls per session and releases only its own holds. Installers preserve unrelated hooks/plugins, keep private backups and handle linked files without deleting managed targets.

CPU presets reuse existing process and CPU criteria, with no new monitor. Their text explains that CPU is system-wide and other work can keep a condition true. Hooks and presets respect Stop-pause.

Validation: 659 Swift tests, 105 release tests, 16 bundle checks and 42 website tests pass with coverage; scoped Qlty passes. A real CLI/socket fixture checks isolated Claude, Codex and OpenCode holds. Generated plugin tests pass under Node and Bun, including missing CLI, duplicate events, ordering, backups and symlinks. UI install actions use temporary configuration. No live agent configuration or model turn was used.

Targets the next release; beta.11 is unchanged. Protocol references are linked in docs/AUTOMATION.md.

Summary by CodeRabbit

  • New Features
    • Added hook integrations for Codex and OpenCode, with controls to install, verify, repair, and remove them.
    • Added editable agent presets that trigger automation when a selected process uses at least 20% CPU.
  • Documentation
    • Added setup guidance for Codex and OpenCode hooks, including configuration, trust requirements, and runtime behavior.

Walkthrough

The pull request adds Codex and OpenCode agent integrations alongside generalized Claude hook handling. It adds OpenCode plugin settings and process-based CPU trigger presets, with tests and documentation for these additions.

Changes: Agent automation

Layer / File(s) Summary
Generalized agent hook handling
Sources/DilatedControl/AgentHookTool.swift, Sources/DilatedControl/ClaudeHooks.swift, Sources/DilatedCLI/DilatedCommand.swift, Tests/DilatedControlTests/AgentAdapterTests.swift, Tests/DilatedControlTests/AgentAdapterProcessTests.swift, scripts/verify.sh
Hook installation, health checks, and input parsing now use tool-specific events and timeouts for Claude, Codex, and OpenCode. CLI dispatch matches each tool’s command name. Tests cover Codex installation and event handling, process-level holds, and execution of the process test suite.
OpenCode plugin lifecycle
Sources/DilatedControl/OpenCodePlugin.swift, Tests/DilatedControlTests/OpenCodeAdapterTests.swift
The plugin forwards session events to the executable and manages installation, health checks, backups, and removal. Tests cover event handling, idempotent installation, modified files, symlinks, and foreign files.
Agent hook settings and guidance
Sources/DilatedUI/Settings/ClaudeHooksSettings.swift, Sources/DilatedUI/Settings/OpenCodeHooksSettings.swift, Sources/DilatedUI/Settings/SettingsWindow.swift, Tests/DilatedUITests/ClaudeHooksSettingsTests.swift, docs/AUTOMATION.md
Settings now include Codex and OpenCode hook management. The views report tool-specific status and installation results; documentation describes configuration, lifecycle events, and trust requirements.
Process-based CPU trigger presets
Sources/DilatedCore/AgentPreset.swift, Sources/DilatedUI/Automation/TriggersSettings.swift, Tests/DilatedCoreTests/AgentPresetTests.swift, docs/AUTOMATION.md
The automation menu adds agent presets. Each preset rule requires an exact process name and CPU usage of at least 20 percent. Tests cover rule evaluation, release, pause behavior, and JSON round-tripping.

Estimated code review effort: 4 (Complex) | ~45 minutes

First pass on Codex/OpenCode adapters and CPU fallback presets. Threat model: single-user local macOS app, not hostile tenants. Check configuration/plugin preservation, shell-free plugin invocation, per-session ordering, quiet failure, PID validation, Stop safety and honest system-wide CPU labeling. Do not add new monitoring subsystems or trust bypasses. Full coverage verification, scoped Qlty and Node/Bun fixtures pass.

Reviewed d8ff422 and the fixture/process evidence. JSON hooks preserve unrelated entries; Codex trust and policy remain user-controlled. OpenCode commands use argument arrays, ordered per-session calls, bounded quiet failure and owned-file checks. Linked managed targets survive removal. CPU presets use existing criteria and disclose system-wide load. Local coverage verification, scoped Qlty and Node/Bun checks pass. Keep CodeRabbit and current CI/coverage gates before merge.

Threat model: a single-user local macOS app reading its owner's agent settings and hook events. Check ownership-preserving installation/removal, per-session isolation and Stop-pause behavior. Hostile local users attacking their own machine and multi-tenant server threats are outside this change.

CodeRabbit found no code issues. I merged the reviewed inspector and duration changes and resolved the test-runner conflict by preserving both the adapter process lane and mounted inspector lane. Agent behavior is unchanged. Integrated verification passes 671 Swift tests, 105 release tests, 16 bundle tests and 43 website tests; scoped Qlty passes. Advisory docstring coverage is not a required repository check.

Reviewed the base merge on 736a2d2. The only conflict was the test-suite selection lines; both required lanes are preserved. The agent patch is unchanged from the completed CodeRabbit pass, and integrated local verification passes.
