Adds OpenCode model variant discovery for thinking controls, passes saved thinking_level through opencode run --variant, and hardens verbose model parsing with fallback coverage.
* fix(runtimes): anchor OpenCode skill + AGENTS.md discovery to task workdir
OpenCode resolves its project discovery root from `--dir` and `PWD`
before falling back to `process.cwd()`. The daemon set `cmd.Dir =
workDir` but never overrode the inherited `PWD`, so OpenCode walked
from the daemon's shell directory and silently bypassed the per-task
workdir — agents lost visibility into `.opencode/skills/` and
`AGENTS.md`, falling back to whatever global skills the host had
installed (MUL-2416).
- Pass `opencode run --dir <workDir>` and override `PWD=<workDir>` in
the child env so AGENTS.md walk-up + `.opencode/skills` project
config scan both anchor on the task workdir.
- Block `--dir` from custom args so user overrides cannot re-introduce
the regression.
- Plumb skill `description` from DB through service / daemon /
execenv. `writeSkillFiles` synthesizes a YAML frontmatter block
(`name`, optional `description`) when the stored content lacks one,
since runtimes like OpenCode silently drop SKILL.md files without a
parseable `name`. Existing frontmatter is preserved unchanged so
upstream-imported skills (GitHub / ClawHub / Skills.sh) keep their
hand-shaped metadata.
Tests:
- New fake-CLI test confirms argv carries `--dir <workDir>` and the
child sees `PWD=<workDir>`.
- New test confirms a user-supplied `--dir` in custom_args is dropped.
- New execenv tests cover synthesized frontmatter and preservation of
pre-existing frontmatter.

* fix(runtimes): inject SKILL.md `name` when upstream frontmatter omits it
Skills imported with frontmatter that sets `description` but leaves `name`
implicit (relying on the directory slug, as common in GitHub/Skills.sh
imports) still hit OpenCode's "no parseable name → drop" path because the
DB Name fallback never made it into the SKILL.md body. ensureSkillFrontmatter
now scans the existing block and, when name is missing or empty, prepends
`name: <slug>` while preserving description, body, and any runtime-specific
keys verbatim.
Also tighten yamlEscapeInline to always double-quote so descriptions that
look like YAML keywords (`null`, `true`, `[foo]`, `{x: y}`, `2024-01-01`)
parse as strings rather than getting reinterpreted and rejected.
Adds regression test for the nameless-frontmatter case and updates the
existing OpenCode skill test for the always-quoted description format.

* 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.
* 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
