21 of the 34 failures on a Windows checkout come from the tests, not from
the code they cover. Three separate causes:
* adapters/shared/file-storage.test.ts builds its worker scripts as source
text and interpolates paths straight into string literals. On Windows
every backslash is then an escape sequence, so the import specifier
C:\Users\...\file-storage.ts reaches bun as C:Users...ile-storage.ts and
the worker exits 1 before it runs:
error: Cannot find package 'C:Usersile-storage.ts'
Module paths now go through pathToFileURL(), data paths through
JSON.stringify(). Both produce byte-identical output on POSIX.
* server/path.test.ts and cli/runtime-app.test.ts asserted against
"/"-spelled literals while the resolvers build paths with the platform
separator. The expectations now come from join(), which returns the very
same strings on POSIX.
* server/paths_sh.test.ts compared paths.sh output (/c/Users/... under Git
Bash) against join(homedir(), ...) (C:\Users\...) — the same directory in
two notations. Both sides are normalised to the shell's notation before
comparing; identity on POSIX.
No production code is touched and nothing is skipped on Windows. The 13
remaining failures are real: the bash statusline renders a broken card
there (sprite collapsed to one character, unclosed bubble, missing name).
That is a separate report, and these tests should keep failing until it is
fixed.
Windows 11, bun 1.3.11: 34 failures -> 13. Not yet run on Linux or macOS;
every change above is an identity there, but CI is the confirmation.

buddy-comment.ts writes .last_stop_hook.<sid> once per Stop event, but the prefix is missing from both cleanup lists — TRANSIENT_PREFIXES in server/state.ts and the pattern list in cli/uninstall.ts. Every session leaves one behind for good, and `claude plugin uninstall` walks past them, so the state dir keeps growing with files nothing reads again. Its siblings .last_comment.<sid> and reaction.<sid>.json are both listed, so this looks like an oversight rather than an intent to keep them. Note the sweep in statusline/buddy-status.sh has the same gap: it expires reaction.* and .last_comment.* on reactionTTL and leaves .last_stop_hook.* alone. That one is left out here on purpose — ramarivera#177 is currently rewriting that script, and this fix does not need to collide with it. Signed-off-by: Michelle <michelle.santiago10@gmail.com>
Completes the previous commit. The uninstall lists only run when the plugin is removed; day to day, stale per-session files are cleared by _sweep_expired_reactions in the statusline, which already expires reaction.* and .last_comment.* on reactionTTL but skipped .last_stop_hook.*. The marker is written by the same atomicWriteTimestamp as .last_comment, in epoch seconds, so it gets the identical loop and cutoff. A fresh marker is kept; reactionTTL=0 still disables the sweep entirely. The new loop sits after the .last_comment one and does not touch any line ramarivera#177 changes in this function, so the two should merge cleanly.

Two separate reasons a plugin install is inert on Windows.
Hooks: Claude Code substitutes ${CLAUDE_PLUGIN_ROOT} into the command as a
plain string and runs it through bash — Git Bash on Windows. The root is
a Windows path, and unquoted, bash eats its backslashes as escapes:
bash: C:UsersmicheAppDataLocalTempcbwrap/hooks/react.sh:
No such file or directory
Quoting the placeholder, as the Claude Code hooks docs recommend, fixes it
and keeps the existing wrappers — including their fallback to
~/.bun/bin, /opt/homebrew/bin and /usr/local/bin when bun is not on PATH.
It also fixes a POSIX plugin root containing a space, which failed the
same way.
MCP server: stdio servers are spawned directly, with no shell, and
Windows cannot spawn a .sh file on its own, so mcp-launcher.sh died with
CONNECTION_CLOSED. The manifest now uses the same `command: "bun"` shape
the installer already writes to .claude.json. The launcher only ever
checked `command -v bun`, so this loses its install hint but no fallback.
Two manifest tests pin both, and fail against the previous manifests.

Claude Code runs hook and status line commands through Git Bash on
Windows, falling back to PowerShell when it finds none — and every hook
and the status line this installer registers is a .sh script that cannot
run there. The install used to finish reporting success and leave dead
config behind. It now stops, with the command to fix it:
winget install --id Git.Git
Git for Windows is not installed automatically like jq below: it is a
machine-wide install behind a UAC prompt, which an installer for a
terminal pet should not spring on anyone. CLAUDE_CODE_GIT_BASH_PATH (which
Claude Code itself honours) points at an install in an unusual place, and
CODING_BUDDY_SKIP_BASH_CHECK=1 is there for whoever only wants the MCP
server and /buddy, the two parts that work without bash.
The jq check tried `sudo apt-get || brew` on every platform. Neither
exists on Windows, so it always fell through to the manual hint. Windows
now gets the same auto-install treatment through winget, which ships with
Windows 10 and later.
`bun run doctor` reports the same Git Bash lookup.

posixPath() rewrote backslashes on every platform. A backslash is a legal character in a POSIX filename, and since both sides of each assertion go through this helper, a path containing one could be corrupted on Linux or macOS while the test still passed.

Still a draft: I'd like a sanity check on the approach, and I can't run the suite on Linux or macOS myself.
The README lists Windows as experimental. This fixes what stops a plugin install from working there, makes the installer say when Windows is missing something, and fixes the test suite's own path handling. It is complementary to #177 (the statusline script itself): no file overlap, and this branch test-merges onto #177 with no conflicts.
Root causes on Windows
On Windows, Claude Code runs hook and status line commands through Git Bash (PowerShell only when Git Bash is absent), and substitutes
${CLAUDE_PLUGIN_ROOT}as a plain string. So.shscripts are fine there — the Claude Code docs even use~/.claude/statusline.shas the Windows example. What breaks is quoting and process spawning:${CLAUDE_PLUGIN_ROOT}unquoted; Git Bash eats the backslashes ofC:\Users\...C:Users...claude-buddy/hooks/react.sh: No such file or directory.shEFTYPE: inappropriate file type or format→CONNECTION_CLOSEDapt-get/brewCommits
test:the suite's own path handling — 34 failures → 13 on Windows. No production code, no new tests, nothing skipped. Worker scripts generated as source text with Windows paths pasted into string literals (error: Cannot find package 'C:Usersile-storage.ts'), POSIX-spelled literals as expectations, and Git Bash vs Node notation for the same directory. Byte-identical on POSIX.fix:sweep.last_stop_hookmarkers inTRANSIENT_PREFIXESandcli/uninstall.ts— not Windows-specific; one is written per Stop event and nothing removes it.fix(statusline):expire them in the TTL sweep too. The new loop sits after the.last_commentone and touches no line fix(statusline): cut Windows subprocess-spawn overhead ~3.5x #177 changes.fix(plugin):quote the plugin root in hooks, launch MCP through bun —"${CLAUDE_PLUGIN_ROOT}"/hooks/react.sh, as the hooks docs recommend. This keeps the existing wrappers and their fallback to~/.bun/bin,/opt/homebrew/binand/usr/local/bin, and also fixes a POSIX plugin root containing a space. The MCP server moves tocommand: "bun", the shape the installer already writes; the launcher only checkedcommand -v bun, so this drops its install hint but no fallback. Two manifest tests pin both, and fail against the previous manifests.fix(install):require Git Bash on Windows, install jq with winget — without Git Bash every hook and the status line this installer registers is dead config, so the install now stops and printswinget install --id Git.Gitinstead of reporting success. It looks atCLAUDE_CODE_GIT_BASH_PATHfirst, which Claude Code itself honours and sets, then the Git for Windows locations;CODING_BUDDY_SKIP_BASH_CHECK=1is there for whoever only wants the MCP server and/buddy. Git is deliberately not auto-installed — machine-wide install behind a UAC prompt. jq is, through winget, mirroring theapt-get/brewauto-install the POSIX branch already does.bun run doctorreports the same lookup.Validation on Windows 11

One root cause:
iconvis absent from Git for Windows (onlymsys-iconv-2.dllships).dwidth()pipes through it, so every width measurement returns 0 and the correctly assembled card is truncated to one column — 11 of the 12 statusline tests fail on that, the 12th is a 5000 ms timeout. #177 already handles a missingiconv, so I left it alone; they should go green once it lands. The 13th,mcp-launcher.sh: exists, is executable, can't pass on Windows: there is no execute bit.Data point for #177: on this machine
