Use when upgrading the larch plugin to the latest stable version. Refreshes the sparse marketplace checkout in place when possible, then reinstalls the plugin to pick up the newest stable release.
Use when authoring or vetting an issue-anchored implementation plan in GitHub (plan markers in the issue body). Two-tier design flow (SIMPLE/HARD) with full plan review and clarify loop; verbal prompts create an issue first.
Use when implementing from a GitHub issue with a vetted in-body plan (run /design first). Materialize, implement, validate, review, PR, CI. See /research, /design, /im, /implement --merge.
Use when cutting a new larch release: gather merged PRs since the last Latest release, generate categorized notes, decide the aggregate semver bump, open and merge the plugin.json bump PR, tag and create the GitHub Release, promote to Latest, then run /upgrade-larch. Private to this larch repo; not plugin exported.
Use when creating shortcut aliases for existing larch skills with preset flags. Auto-routes to plugin tree skills/ inside Claude plugin source repos, dev-only .claude/skills/ elsewhere; --private forces dev-only.
Use when creating GitHub issues with LLM-based semantic duplicate detection plus always-on inter-issue blocker-dependency analysis. Single or batch mode. Flags: --dry-run, --no-dedup, --no-dep-llm, --title-prefix, --label.
Use when conducting read-only research; planner pre-pass + 4 Codex-first lanes (arch/edge/ext/security) with Claude fallback; 3-reviewer panel (Claude+Codex+Cursor); --no-issue skips auto-issue.
Use when reviewing code changes (--diff for branch diff, or positional text for existing code review). Description mode records accepted OOS items in local artifacts for manual `/issue` follow-up.
