* fix(agent/opencode): bypass npm .cmd shim on Windows to preserve multi-line prompts
The npm-generated `opencode.cmd` shim forwards argv via Windows batch `%*`,
which silently truncates positional arguments at the first newline. The
daemon spawns OpenCode with a multi-line prompt (system prompt + user
message), so on Windows the agent only ever sees the first line and
responds generically as if it never received the user's message
(reported in #1717 with native-binary repro confirming the same prompt
arrives intact when cmd.exe is skipped).
When `runtime.GOOS == "windows"` and `exec.LookPath` returns a `.cmd`
shim, walk to the native binary that npm bundles next to the shim:
<prefix>\opencode.cmd
<prefix>\node_modules\opencode-ai\node_modules\opencode-windows-x64\bin\opencode.exe
If the native binary is missing (unusual install layout), keep the
original shim path so PATH lookup still wins. The resolver is a pure
function with an injectable `statFn`, so layout assertions are testable
on Linux:
- shim resolves to the bundled native binary
- missing native returns "" (caller keeps original path)
- non-cmd paths (Linux/Mac binary, opencode.exe direct, empty) skip resolution
- uppercase `.CMD` is accepted (PATHEXT entries can be either case)
Closes the user-facing failure mode without restructuring exec resolution
across the rest of the agent backends — the other shim-aware fixes can
follow the same shape if/when they land in similar repros.
* fix(agent/opencode): cover x64-baseline and arm64 npm package variants
`npm install -g opencode-ai` ships three Windows platform packages
(opencode-windows-x64, opencode-windows-x64-baseline for older CPUs
without AVX2, opencode-windows-arm64 for Surface / Copilot+ PC) and
installs whichever matches the host. The previous resolver only knew
about opencode-windows-x64, so baseline-x64 and arm64 hosts would fall
back to the .cmd shim and hit the multi-line prompt truncation again.
Iterate the three package candidates in GOARCH-preferred order. ARM64
hosts try arm64 first; everything else tries x64, then baseline, then
arm64 as a last resort. Cost is one extra statFn call per miss when
the GOARCH-preferred package isn't installed.
Surfaced by review on #1718.
* test(agent): add Windows counterpart to writeTestExecutable
writeTestExecutable in exec_fixture_unix_test.go is referenced by
claude_test.go / codex_test.go / kimi_test.go, but the //go:build unix
constraint meant `go test ./pkg/agent` failed to build on Windows.
ETXTBSY is a Linux/Unix fork-exec race; Windows doesn't have that
pathology, so a plain os.WriteFile is sufficient.
Lifted from #1719 (Codex) with attribution. Surfaced by review on #1718.
* fix(daemon): suppress agent terminal windows on Windows (#1471)

* fix: add hideAgentWindow to detectCLIVersion and avoid SysProcAttr overwrite
- Add missing hideAgentWindow(cmd) call in detectCLIVersion (claude.go:554)
so --version checks don't flash console windows on Windows.
- Refactor hideAgentWindow to preserve existing SysProcAttr fields
instead of overwriting the entire struct.

Surface the actual exec path + argv for every agent backend at INFO
so operators can see the exact command without flipping to debug.
Also add the missing log line in pi.go for consistency with the
other nine backends.
Add a debug-level log line in every agent backend (claude, codex,
opencode, openclaw, gemini, hermes) that prints the executable path
and full argument list when spawning the agent process. Helps diagnose
custom args, model overrides, and other CLI flag issues.
* feat(agent): add custom CLI arguments support
Allow users to configure custom CLI arguments per agent that get
appended to the agent subprocess command at launch time. This enables
use cases like specifying different models (--model o3), max turns,
or other provider-specific flags without needing separate runtimes.
Changes:
- Add custom_args JSONB column to agent table (migration 041)
- Update API handler to accept/return custom_args in create/update
- Pass custom_args through claim endpoint to daemon
- Append custom_args to CLI commands for all agent backends
- Add ExecOptions.CustomArgs field in agent package
- Add Custom Args tab in agent detail UI
- Add --custom-args flag to CLI agent create/update commands
Closes MUL-802
* fix(agent): filter protocol-critical flags from custom_args
Add per-backend filtering of custom_args to prevent users from
accidentally overriding flags that the daemon hardcodes for its
communication protocol (e.g. --output-format, --input-format,
--permission-mode for Claude).
This follows the same pattern as custom_env's isBlockedEnvKey: we
only block the small, stable set of flags that would break the
daemon↔agent protocol — not every possible dangerous flag. Workspace
members are trusted for everything else.
Each backend defines its own blocked set:
- Claude: -p, --output-format, --input-format, --permission-mode
- Gemini: -p, --yolo, -o
- Codex: --listen
- OpenCode: --format
- OpenClaw: --local, --json, --session-id, --message
- Hermes: none (ACP is positional)
Includes unit tests for the filtering logic.
* fix(agent): address code review nits for custom_args
- Replace module-level `nextArgId` counter with `crypto.randomUUID()`
in custom-args-tab.tsx to avoid SSR ID conflicts
- Add unit tests for custom args passthrough and blocked-arg filtering
in both Claude and Gemini arg builders
When an agent CLI process hangs (e.g. a tool call blocks on unreachable
I/O), the daemon's scanner blocks indefinitely on stdout, preventing the
Result from ever being sent. This causes tasks to stay in "running"
state permanently with no further events.
Three-layer fix:
1. Agent backends (claude, opencode, openclaw, gemini): add a watchdog
goroutine that closes the stdout/stderr pipe when the context is
cancelled, forcing the scanner to unblock. Also set cmd.WaitDelay
so Go force-closes pipes after 10s if the process doesn't exit.
2. daemon executeAndDrain: add an independent drain timeout (backend
timeout + 30s buffer) with context-aware select on both the message
channel and the result channel, so the daemon never blocks forever.
3. daemon ping path: add context-aware select so pings don't deadlock
if the agent backend stalls.

1. Separate ReportTaskUsage endpoint (POST /api/daemon/tasks/{id}/usage)
so usage is captured independently of complete/fail — fixes usage loss
for failed/blocked tasks.
2. Add usage tracking for all four providers:
- Claude: already done (stream-json message.usage)
- OpenCode: extract from step_finish.part.tokens
- OpenClaw: extract from step_end.data token fields
- Codex: extract from turn/completed and task_complete usage fields
3. Remove usage from CompleteTask payload — all usage goes through the
dedicated endpoint now.
* feat(daemon): add opencode as supported agent provider
Add opencode backend alongside claude and codex. The backend spawns
`opencode run --format json`, parses streaming JSON events (text,
tool_use, error, step_start/finish), and supports --prompt for system
prompts. Includes CLI detection, AGENTS.md runtime config, native skill
discovery via .config/opencode/skills/, and 21 tests covering handlers,
JSON parsing, and integration-level processEvents scenarios.
* chore: add .tool-versions to gitignore
