cmux-dev-workflowContributor rules for the cmux repo: tagged Debug builds through reload.sh, first-time setup, Xcode project normalization and per-tag sidebar extension points.
After any code change the agent builds the Debug app with `./scripts/reload.sh` and a short tag. By default the script builds without launching, and `--launch` opens the app. Bare `xcodebuild` and untagged `cmux DEV.app` are off limits, because untagged builds share the default debug socket and bundle ID with other agents, which causes conflicts and stolen focus. CLI or socket testing against a tagged build goes through `scripts/cmux-debug-cli.sh` with `CMUX_TAG` set, never the `/tmp/cmux-cli` symlink, and cmuxd is rebuilt for release with `zig build -Doptimize=ReleaseFast`.
Initial setup runs `./scripts/setup.sh`, which initializes submodules, builds GhosttyKit and installs a pre-commit hook that runs `scripts/normalize-pbxproj.py` on a staged `project.pbxproj` to sort the high-churn sections. CI runs `scripts/check-pbxproj.sh` to enforce the pin. The team is pinned to Xcode 26.x through `.xcode-version`, with `objectVersion = 60`, and changing that needs a team decision. Each tagged dev build also gets its own ExtensionKit sidebar extension point so concurrent builds do not collide. Three reference files go deeper on tagging and normalization.

cmux Contributor Dev Workflow loads about 1.5k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 69 tokens; SKILL.md has 653 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/cmux-dev-workflow/SKILL.md (or your agent's skills folder). This skill also uses 4 other files; get the full folder from GitHub.After making code changes, always run the reload script with a tag to build the Debug app:
./scripts/reload.sh --tag <short-tag>By default, reload.sh builds but does not launch the app. Pass --launch only when you need to open it automatically.
Never run bare xcodebuild or open an untagged cmux DEV.app. Untagged builds share the default debug socket and bundle ID with other agents, causing conflicts and stealing focus.
For CLI or socket dogfood against a tagged Debug app, use the tag-bound helper and set CMUX_TAG:
CMUX_TAG=<tag> scripts/cmux-debug-cli.sh list-workspacesDo not use /tmp/cmux-cli for tagged dogfood. That symlink points at the most recently reloaded build.
When rebuilding cmuxd for release/bundling, always use ReleaseFast:
cd cmuxd && zig build -Doptimize=ReleaseFastRun the setup script to initialize submodules, build GhosttyKit, and install the pbxproj normalization pre-commit hook:
./scripts/setup.shThe team is pinned to Xcode 26.x. .xcode-version records the major; cmux.xcodeproj/project.pbxproj carries objectVersion = 60, which is what Xcode 26 writes by default. (objectVersion 77 is reserved for projects that adopt synchronized folder groups, which cmux does not use yet. Bumping to a different value requires a deliberate team decision.)
scripts/setup.sh installs a tracked pre-commit hook (scripts/git-hooks/pre-commit) that runs scripts/normalize-pbxproj.py on any staged cmux.xcodeproj/project.pbxproj, sorting the high-churn sections so Xcode's nondeterministic reordering never reaches a commit. The hook is idempotent. CI runs scripts/check-pbxproj.sh to enforce both the objectVersion pin and normalization, so anyone who skips the hook (or never ran setup) gets a clear failure on their PR.
.xcode-version is the single source of truth. To bump the pin: edit .xcode-version, open cmux.xcodeproj in the new Xcode (which rewrites objectVersion automatically when it touches the file), and add a case for the new Xcode major in scripts/check-pbxproj.sh mapping it to the objectVersion that major writes.
Each tagged dev build gets its own ExtensionKit sidebar extension point so concurrent dev builds don't collide. Three build settings drive this:
CMUX_SIDEBAR_EXTENSION_POINT_ID (default com.cmuxterm.app.cmux.sidebar): the extension point identifier baked into Info.plist at build time.CMUX_BUNDLE_ID_SUFFIX (default empty): inserted into the app and appex bundle ids so a tagged extension gets a distinct identity that pkd records separately.CMUX_DISPLAY_NAME_SUFFIX (default empty): appended to the appex CFBundleDisplayName. The OS groups sidebar extensions by display name for the enable/disable + availability counts the host reads (AppExtensionIdentity exposes only bundleIdentifier, localizedName, extensionPointIdentifier, id — cmux already keys its own identity off the stable bundleIdentifier, but the OS-level grouping is by name). Two same-named appexes installed side by side (a base build and a tagged build) are treated as one logical extension, so toggling one perturbs the other; a per-tag display name keeps them distinct.The host resolves its point id at runtime from the Info.plist key CMUXSidebarExtensionPointIdentifier via CmuxSidebarExtensionPoint.identifier(in:). ./scripts/reload.sh --tag <tag> scopes the host point to com.cmuxterm.app.debug.<tag>.cmux.sidebar. ./scripts/reload-extension.sh --tag <tag> [--host-bundle-id <id>] [--example sample|tabs|both] builds a matching tag-scoped sample extension, passing CMUX_SIDEBAR_EXTENSION_POINT_ID=<host-bundle-id>.cmux.sidebar, CMUX_BUNDLE_ID_SUFFIX=.<tag>, and CMUX_DISPLAY_NAME_SUFFIX=" <tag>". It installs exactly what xcodebuild produced (xcodebuild ad-hoc signs with entitlements intact) — it does NOT re-sign, because a bare codesign --force --sign - strips the appex entitlements and the extension then drops its host XPC connection. pkd ingests the tagged copy because its bundle id is distinct. Verify with pluginkit -m -p <host-bundle-id>.cmux.sidebar.
To author a NEW sample extension that is tag-ready:
EXAppExtensionAttributes:EXExtensionPointIdentifier = $(CMUX_SIDEBAR_EXTENSION_POINT_ID).CMUX_SIDEBAR_EXTENSION_POINT_ID (default com.cmuxterm.app.cmux.sidebar), CMUX_BUNDLE_ID_SUFFIX (default empty), and CMUX_DISPLAY_NAME_SUFFIX (default empty) build settings to the app and appex targets in all build configs.PRODUCT_BUNDLE_IDENTIFIER = <appBase>$(CMUX_BUNDLE_ID_SUFFIX) for the app target and <appBase>$(CMUX_BUNDLE_ID_SUFFIX).<leaf> for the appex (suffix before the appex leaf so the appex id stays prefixed by the app id).INFOPLIST_KEY_CFBundleDisplayName (or the CFBundleDisplayName Info.plist value) = <Name>$(CMUX_DISPLAY_NAME_SUFFIX)..xcode-version or cmux.xcodeproj/project.pbxproj.pluginkit verification.© disler, MIT.
