* fix(agent-hooks): make the Windows managed hook survive Claude-hooks-compat consumers `~/.claude/settings.json` is not read only by Claude Code. Third-party Claude-hooks-compat layers (cursor-agent, Devin) import the same file and reimplement hook execution, so Orca's entry has to survive consumers that support strictly less than the documented schema. Three separate defects came from assuming otherwise. 1. The entry depended on `args`, which a compat consumer ignores. `args` is valid Claude Code syntax, but cursor-agent spawns `command` alone -- so `conhost.exe` ran bare, which opens an interactive console that never closes. Hook payloads were typed into those stranded shells (#14815). The entry is now one self-contained `command` string that depends on nothing optional. 2. `conhost.exe --headless` never relayed anything. It implements the ConPTY server protocol, not a generic no-window wrapper: it does not wait for the hosted process and relays neither exit code nor stdout. Measured directly -- `conhost --headless cmd /c "echo X& exit /b 42"` yields empty stdout and no exit code, while the replacement returns both and waits. So every hook was fire-and-forget, and whatever it printed was discarded. Replaced with `-WindowStyle Hidden`, which suppresses the window and keeps wait/exit-code/stdout intact. 3. The hook never wrote anything to stdout. Guards exited silently and curl's output went to nul. Claude Code documents empty stdout as "no decision", but cursor-agent treats PreToolUse as a permission gate, fails to parse empty stdout as JSON, and blocks the tool call -- so every shell command in every cursor-agent session on Windows failed (#14818). The script now writes `{}` first, on both the Windows and POSIX branches, which is documented to be identical to writing nothing for real Claude Code. Gemini and Antigravity already did this. Defects 2 and 3 are causally linked: `{}` cannot reach any consumer while conhost is swallowing stdout, so neither fix works without the other. Also fixed while establishing the contract: - The launcher's own missing-script fallback returned empty stdout, reproducing #14818 whenever `~/.orca` was cleaned or an install was half-finished. It now emits `{}` too. - PowerShell serializes progress records to stderr as CLIXML when stderr is redirected; a consumer merging stderr into stdout would see those bytes before the JSON. Every encoded payload now silences progress. - `runtime-home-hook-command.ts` built its own launcher without window suppression -- exactly the drift #14815 asks to prevent. All launcher construction now goes through `windows-powershell-hook-launcher.ts`, so the switch list cannot be present in one installer and missing in another. - Renamed `usesWindowsHeadlessHook` to `usesWindowsPowerShellLauncher`; nothing is headless anymore, and the flag selects a launcher. Testing: the new regression test asserts the effect a consumer observes -- it runs the exact `command` string from settings.json through both cmd.exe and Git Bash, across the guard-exit, reached-curl, and missing-script paths, and parses stdout. Verified it fails when `conhost --headless` is reintroduced. The previous tests all asserted installer intent, which is why they passed through all three defects. * fix(agent-hooks): close hook launcher review gaps --------- Co-authored-by: OrcaWin <293788423+OrcaWin@users.noreply.github.com>
