v6.2.1

Release 6.2.1 — 2026-11-04

Summary

ycc 6.2.1 removes the linear-personal MCP server from ycc-mcp on every runtime; linear is now the only Linear server. It also fixes saved external_directory approvals in the opencode npm package and a CRLF .gitignore check in branch prep, and registers the deferred Pi target in the package model.

Added

8950f6b feat(scripts): harden live-harness bwrap sandbox with a shared layout (YAN-1905) (#524)

Packages

Package	Runtime	Status	Mechanism	Listed	Version or target	Notes
@yandy-r/ycc-opencode	opencode	included	npm	no	6.2.1	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	6.2.1	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	6.2.1	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	6.2.1	Ships through the GitHub marketplace; no cursor.com submission before post-6.0.
ycc	omp	included	native	yes	6.2.1	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	pi	deferred	native	no	target v6.3.0	Deferred: generated Pi package under packages/pi/ycc (pi >=1.2.0, recommended 1.5.0) with skills, _shared, ycc: command and subagent extensions, and agent data; rewrites ${CLAUDE_PLUGIN_ROOT}, /ycc: and $ARGUMENTS, which Pi leaves literal. Pi has no catalog: install.sh --target pi will run pi install . No generator or installer ships yet.
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	6.2.1	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-all	pi	excluded	native	no	target v6.3.0	Excluded: Pi packages cannot depend on Pi packages, so ycc-all (on Claude the union of ycc, ycc-mcp, and ycc-hooks) has no Pi package; install ycc and ycc-mcp separately; ycc-hooks is excluded on Pi and herdr reporting comes from herdr integration install pi.
ycc-hooks	claude	included	native	yes	6.2.1	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	6.2.1	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-hooks	pi	excluded	native	no	target v6.3.0	Excluded: Pi never runs shell hooks or hooks.json, and WorktreeCreate has no Pi event. herdr reporting is herdr's own integration (herdr integration install pi), and ycc ships no Pi hook extension (ADR 0003).
ycc-mcp	claude	included	native	yes	6.2.1	Native MCP-only plugin.
ycc-mcp	codex	included	native	yes	6.2.1	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	6.2.1	Native MCP-only plugin.
ycc-mcp	omp	included	native	yes	6.2.1	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-mcp	pi	deferred	native	no	target v6.3.0	Deferred: extension package (pi >=1.2.0) whose registrar calls pi.registerMcpServer for the shipped server set read as package data, because Pi never reads mcp.json from a package; a same-name user mcp.json entry wins, tools become mcp____, and SSE servers are rejected. An opt-in install.sh --mcp merge into /mcp.json is the fallback for pi mcp shell commands.
ycc-rules	cursor	included	native	yes	6.2.1	Cursor-only rules package. No Claude ycc-rules: Claude rules stay on install.sh (see installer-fallback claude).
ycc-rules	omp	included	native	yes	6.2.1	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).
ycc-rules	pi	deferred	native	no	target v6.3.0	Deferred: extension package (pi >=1.2.0) carrying the rule files and a path-rule injector that attaches a family's rules after a matching read, edit, or write. Always rules use the installer-fallback AGENTS.md link.

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

Validation

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

Upgrade Notes

Removing a server from the source does not delete it from configs that an earlier install.sh merged. To drop linear-personal, run ./install.sh remove --target <claude|cursor|codex|opencode> --intent mcp --mcps linear-personal --global from a v6.2.0 checkout, or delete the entry by hand. Native ycc-mcp plugins pick up the change on update. If you edited the entry yourself, add --force.

Publishing the v6.2.1 tag ships the experimental, opt-in @yandy-r/ycc-opencode package. The install.sh file copy remains the primary opencode path.
