v6.1.0

Release 6.1.0 — 2026-10-23

Summary

ycc 6.1.0 adds native support for OMP (oh-my-pi), with omp 18.12.2 or later. The ycc, ycc-mcp and ycc-rules OMP packages are listed in the root .omp-plugin/marketplace.json. install.sh --target omp installs, updates, removes and migrates them at user or project scope. The release also adds item selection to install.sh (--skills, --agents, --commands, --plugins, --mods, --hooks and --with-deps), and fixes for the opencode restricted-agent permissions. A new live CI workflow runs the OMP acceptance harnesses against pinned omp releases on Linux and macOS.

Packages

Package	Runtime	Status	Mechanism	Listed	Version or target	Notes
@yandy-r/ycc-opencode	opencode	included	npm	no	6.1.0	experimental; opt-in; not yet published; Experimental and opt-in in v6; the @yandy-r npm scope is already owned. The V2 setup hook registers components and delivers instructions through the context hook; install.sh file copy stays the primary opencode path.
ycc	claude	included	native	yes	6.1.0	Shipping entry; stays visible in every catalog throughout the v6 flip. status-bar@ycc-mods is versioned independently and stays outside this manifest.
ycc	codex	included	native	yes	6.1.0	Listed in the ycc Codex catalog (.agents/plugins/marketplace.json) with a local source at ./.codex-plugin/ycc; installs together with ycc-mcp. Replaces the legacy local-ycc-plugins catalog.
ycc	cursor	included	native	yes	6.1.0	Ships through the GitHub marketplace; no cursor.com submission before post-6.0.
ycc	omp	included	native	yes	6.1.0	Generated OMP package under packages/omp/ycc (omp >=18.12.2) with .omp-plugin and .claude-plugin manifests and package.json, rewritten ${CLAUDE_PLUGIN_ROOT}, /ycc: and _shared references, agents translated to @ROLE models, and one commands/.md entrypoint per public skill (/ycc:). Listed in the root .omp-plugin/marketplace.json (YAN-1180). install.sh --target omp exports it to a local marketplace (--mode local) or registers the repository catalog (--mode repo) and installs it through omp plugin (user or project scope).
ycc-agents	claude	deferred	native	no	target v7.0.0	Deferred to v7.0.0 as a breaking change with qualified ycc-agents: references; the v6 namespace spike rejects a shared manifest name. Hidden prep: claude_agents_split.py builds and validates the split on demand (claude-native check); test-claude-agents-split.sh is the opt-in live dispatch proof.
ycc-all	claude	included	native	yes	6.1.0	Meta plugin that installs ycc, ycc-mcp, and ycc-hooks through Claude plugin dependencies.
ycc-all	omp	excluded	native	no	target v6.1.0	Excluded: the OMP marketplace does not read plugin dependencies, so ycc-all (on Claude the union of ycc, ycc-mcp, and ycc-hooks) is omitted from the OMP catalog; install ycc and ycc-mcp separately; herdr reporting comes from herdr integration install omp.
ycc-hooks	claude	included	native	yes	6.1.0	Native plugin hooks/hooks.json needs Claude Code 2.1.300 or later; older clients keep installer-managed hooks. After enabling ycc-hooks@ycc, install.sh migrate --target claude --apply prunes the installer hooks.
ycc-hooks	codex	excluded	native	no	target v6.0.0	Excluded: NO-GO until verified under YAN-1149 (YAN-1149 gate). Hooks stay out of the Codex bundle.
ycc-hooks	cursor	included	native	yes	6.1.0	sessionStart only; WorktreeCreate stays on install.sh.
ycc-hooks	omp	excluded	native	no	target v6.1.0	Excluded: herdr ships its own OMP integration (herdr integration install omp), which reports the session and agent state; a ycc reporter is ignored by herdr (non-herdr source) or corrupts herdr's ordering (herdr:omp). WorktreeCreate has no OMP event. ycc ships no OMP hooks (YAN-1174); its only OMP extension is the agent scope guard inside the ycc package (YAN-1250).
ycc-mcp	claude	included	native	yes	6.1.0	Native MCP-only plugin.
ycc-mcp	codex	included	native	yes	6.1.0	Native MCP-only plugin; carries the MCP servers the Codex ycc plugin used to ship. Listed together with ycc.
ycc-mcp	cursor	included	native	yes	6.1.0	Native MCP-only plugin.
ycc-mcp	omp	included	native	yes	6.1.0	Generated OMP package under packages/omp/ycc-mcp (omp >=18.12.2) with .omp-plugin and .claude-plugin manifests, package.json, and a root .mcp.json byte-identical to mcp-configs/mcp.json (secret-literal audited; ${VAR} env placeholders stay unexpanded until omp starts a server). Servers load as ycc-mcp:. Listed in the root .omp-plugin/marketplace.json (YAN-1180). install.sh --target omp installs it next to ycc through omp plugin (user or project scope); a running session picks it up after /reload-plugins or a restart.
ycc-rules	cursor	included	native	yes	6.1.0	Cursor-only rules package. No Claude ycc-rules: Claude rules stay on install.sh (see installer-fallback claude).
ycc-rules	omp	included	native	yes	6.1.0	Generated package under packages/omp/ycc-rules (omp >=18.12.2): 31 flat rules named ycc--, paths→globs, description kept, alwaysApply only when true. Language rules are rulebook entries read via rule://; 5 description-less ycc--trigger TTSR rules (glob-gated edit/write, interruptMode never) attach them once per session and once per subagent that edits a matching file. Listed in the root .omp-plugin/marketplace.json (YAN-1180).

File-copy packages (the installer fallback) have no native manifest and are not versioned here.

Validation

• ./scripts/sync.sh — OK

• python3 -m json.tool .claude-plugin/marketplace.json — OK
• python3 -m json.tool ycc/.claude-plugin/plugin.json — OK

Upgrade Notes

No breaking changes; existing Claude, Codex, Cursor and opencode installs need no action.

• OMP users: run omp plugin marketplace add https://github.com/yandy-r/ystack.git, then omp plugin install ycc@ycc ycc-mcp@ycc ycc-rules@ycc. Alternatively, run install.sh install --target omp. To upgrade, run a bare omp plugin upgrade. omp 18.12.6 upgrades only the first target when given several (upstream can1357/oh-my-pi#16826).
• Native Windows is unsupported for the OMP target; WSL 2 is expected to work but is unverified. See docs/install/omp.md.
