One data point on the discovery path, in case it's useful for scoping this. I hit this exact symptom (Kimi Code showing "CLI needed" on a GUI-launched Buzz while $ ls ~/.kimi-code/bin
rg
$ command -v kimi
/Users/…/.bun/bin/kimi -> ../install/global/node_modules/@moonshot-ai/kimi-code/dist/main.mjs
The underlying cause is the same one this PR's comment describes, and it isn't Kimi-specific: I opened #3343 to add |
## Problem `common_binary_paths()` probes mise shims, `~/.local/bin`, volta, asdf, and (further down `resolve_command_uncached`) nvm's default bin dir — but not bun's global bin directory, `~/.bun/bin`. bun's installer appends its bin dir to `~/.zshrc` / `~/.bashrc`, which are **interactive**-only. A login shell never sources them, so `find_via_login_shell()` can't recover the path either. That's the same failure mode already called out in this file for nvm: ```rust // Check nvm's default Node.js bin directory — nvm initializes via // ~/.zshrc (interactive) which is not loaded by a login shell, so // `node`, `npm`, and npm-global shims installed there are otherwise // invisible. ``` So for a GUI-launched desktop app, every rung of the resolution ladder misses a bun-installed CLI: 1. workspace dev dirs — no 2. `command_looks_like_path` — no, presets use bare names 3. Buzz-managed npm/node dirs — no 4. current process PATH — launchd's minimal PATH on a Finder launch 5. `find_via_login_shell` — `.zshrc` not sourced 6. `common_binary_paths()` — **`~/.bun/bin` absent** 7. nvm default bin — no This matters because bun is a common install route for the agent CLIs Buzz targets. Kimi Code in particular ships as an npm package (`@moonshot-ai/kimi-code`), so `bun add -g` puts it at `~/.bun/bin/kimi` — exactly where discovery doesn't look. ## Reproduction On macOS with `codex` and `kimi` installed via bun, launching Buzz from Finder: - Kimi Code shows **"CLI needed"** - both CLIs run fine in an interactive terminal Probing the way `find_via_login_shell` does, in a clean environment: ```console $ env -i HOME=$HOME /bin/zsh -l -c 'command -v -- codex; command -v -- kimi' (nothing) ``` Launching the app with the bun dir on PATH resolves both immediately: ```console $ env PATH="$HOME/.bun/bin:$PATH" /Applications/Buzz.app/Contents/MacOS/buzz-desktop ``` ## Change One entry appended to the home-relative list in `common_binary_paths()`. It goes **last** so it cannot shadow a directory that already resolves — the change can only add resolutions, never alter existing ones. ## Testing `cargo fmt --check` passes. I was not able to run the full `just ci` gate locally: `ring 0.17.14` fails to build in this environment against the macOS 26.2 SDK (`cc` error compiling `p256-nistz.c`), which is unrelated to this change. Relying on CI for the rest — the diff adds one `PathBuf` to an existing `Vec<PathBuf>` and introduces no new API. ## Notes - Related to #3084, which adds `~/.kimi-code/bin` for the same class of GUI-launch discovery failure. That covers Kimi's standalone installer; this covers the bun/npm-global install route. They're complementary — I've left a note on that PR. - Only `~/.bun/bin` is added. bun's global packages live under `~/.bun/install/global/node_modules` but are symlinked into `~/.bun/bin`, so the single directory is sufficient. - Worth noting `~/.bun/bin` contains no `node`/`npm`/`npx`, so appending it can't shadow a system Node toolchain.
