feat(install): add ZCode host support - #63
Conversation
ZCode discovers user-scope skills in ~/.zcode/skills/ and slash commands in ~/.zcode/commands/. This adds zcode to both installers (install.sh --zcode / --hosts zcode, and bun scripts/install.ts --hosts zcode) with detect/install/validate/uninstall/status parity to the other hosts. Agents and hooks are intentionally not installed: ZCode loads them from plugins only.
📝 WalkthroughWalkthroughChangesZCode host support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new ZCode support can leave shell and Bun installers with conflicting ownership records, which may delete recreated user skills during uninstall or leave stale cleanup state. The Bun path also copies non-Markdown command entries that the shell installer excludes. Merge should wait for these bounded installer-consistency issues to be addressed or explicitly accepted.

Pull request overview
Adds ZCode as a first-class installer host across both the Bash and Bun installers, aligning docs/tests so ~/.zcode/skills and ~/.zcode/commands can be installed/uninstalled via the standard manifest flow (without installing agents/hooks for ZCode).
Changes:
- Add
zcodehost support toscripts/install.sh(detect/install/validate/uninstall/status + CLI flags). - Add
zcodehost entry toscripts/install.ts(data-drivenHOSTS[]config + CLI help update). - Update docs and tests to include ZCode in supported host lists and installer behavior.

When --zcode is rerun for an upgrade, every ${home}/skills/${name} destination already exists. Per cp --help, this invocation is treated as the SOURCE... DIRECTORY form, so copy_item executes cp -R "$src" "$dest" and creates a nested ${name}/${name} directory rather than updating the existing skill; reproducing two installs leaves the old top-level SKILL.md alongside test-driven-development/test-driven-development/SKILL.md, so ZCode continues loading the stale version. Replace the managed destination first or copy the source contents into it.
Useful? React with 👍 / 👎.

When ZCode was installed with bun scripts/install.ts --hosts zcode, ownership is recorded only in ~/.xpowers/manifest.json by install.ts, but this path reads only ~/.zcode/.xpowers-manifest. Consequently, a later documented install.sh --hosts zcode --uninstall --yes reports that no manifest exists, exits unsuccessfully, and leaves all managed files behind. Add the same JSON-manifest interoperability used for Kimi Code or otherwise delegate this uninstall path.

Reconcile ZCode ownership when users switch installers.
The shell installer writes ~/.zcode/.xpowers-manifest. The Bun installer records ZCode only in ~/.xpowers/manifest.json. Neither lifecycle updates or removes the other record.
If a user switches installers, uninstalls with the second installer, recreates a skill with an XPowers-managed name, and then runs the first installer uninstall, the stale manifest can recursively delete that recreated user skill. The reverse order leaves the Bun manifest stale too.

Filter ZCode commands to Markdown files.
Line 555 has no pattern, so the Bun installer copies every top-level entry in commands/. The shell installer copies only commands/*.md. Set pattern: "*.md" to keep both installers aligned with the ZCode slash-command contract.

Description
Adds ZCode as an installer host in both installers, alongside the existing seven hosts:
scripts/install.sh --zcode(or--hosts zcode, included in--alldetection via~/.zcode)bun scripts/install.ts --hosts zcodeZCode discovers user-scope skills from
~/.zcode/skills/and slash commands from~/.zcode/commands/, so the host installs exactly those two surfaces with the standard manifest-tracked uninstall (user-created skills are preserved). Agents and hooks are intentionally not installed — ZCode loads both from plugins only, so copying them into~/.zcodewould be dead weight. This also avoids~/.agents/skills, which the Codex fallback path already claims.Install shape per host follows the existing conventions: skills copied from
skills/(minuscommon-patterns, matching Claude), commands fromcommands/*.md,.xpowers-versionmarker,.xpowers-manifestfor uninstall, plus detect/validate/uninstall/status parity ininstall.shand a data-driven entry in theinstall.tsHOSTS[]array.Related Issues
