Seven blocking issues prevented kimicode from working on Windows. None
were guarded by isWindows checks because the plugin was authored
without importing it. Symptoms ranged from silent agent launch
failures to misclassified process state to total session-discovery
breakage.
1. getLaunchCommand emitted bare command strings ("kimi --work-dir
...") which PowerShell parses as a quoted expression rather than
executing. Wrap with formatLaunchCommand() so Windows gets the
"& " call operator, matching agent-codex.
2. isProcessRunning called ps -eo on the tmux branch with no platform
guard. ps does not exist on Windows, so a stale tmux handle would
throw and misclassify a live agent as exited. Added the same
isWindows() return-false guard agent-codex uses.
3. resolveWorkspacePath called realpath() unconditionally. On Windows,
Node's realpath silently canonicalizes non-existent paths instead
of throwing ENOENT — turning "/workspace/test" into
"D:\workspace\test" and diverging the session-discovery hash from
any caller that hashed the raw input. Stat first so the catch path
is reached uniformly across platforms.
4. isInsideKimiSessions hardcoded "/" as the path separator in the
sandbox check. realpath returns native paths (backslashes on
Windows) so candReal.startsWith(rootReal + "/") never matched —
every candidate was rejected and findKimiSessionMatch returned
null forever. Use path.sep.
5. getEnvironment set PATH and GH_PATH locally with hardcoded POSIX
values. session-manager already injects both for every agent
plugin, so the local writes were dead code that masked the
Windows-aware central logic. Drop them; mirror agent-codex.
6. getLaunchCommand passed config.systemPromptFile via --agent-file,
but kimi expects --agent-file to be a YAML agent spec, not arbitrary
markdown. AO writes the orchestrator prompt as a plain .md file, so
kimi exited with 'Invalid YAML in agent spec file: expected
<document start>, but found <block sequence start>' on the first
bullet. Read the file synchronously and inline its contents into
--prompt instead, concatenating with any existing config.prompt.
7. session-manager listed kimicode in requiresNativeRestore, so when
getRestoreCommand returned null (because the previous launch failed
before kimi wrote any session data), AO threw
SessionNotRestorableError instead of falling back to a fresh
getLaunchCommand. Removed kimicode from the allowlist; falling back
is the only sensible behavior when there is no session on disk to
resume.
Tests: switched the per-suite workspace constant to a per-test
mkdtemp-scoped path so a coincidental directory at /workspace/test
on the host doesn't make Windows realpath canonicalize it. Mocked
isWindows so platform-aware production code can be exercised
deterministically. Made the shell-escape prompt assertion
platform-aware (POSIX 'backslash-quote' vs PowerShell double-quote).
Replaced the --agent-file tests with system-prompt-content-into-prompt
assertions backed by a real temp file under fakeHome.
Result: all 103 tests pass on Windows (was 30 failures pre-fix).
