<objective> Edit the phase list in ROADMAP.md safely. `add` and `edit` are near-trivial markdown changes; `insert` and `remove` are not - they shift phase numbers, and a phase number lives in four places that must move together or the project's references rot. This skill keeps them consistent. </objective> <execution_context> @${CLAUDE_PLUGIN_ROOT}/cadence-core/workflows/phase.md @${CLAUDE_PLUGIN_ROOT}/cadence-core/references/git-guard.md </execution_context> <process> Route on `$ARGUMENTS` (add | insert N | remove N | edit N) and run the phase workflow. For insert/remove, do the full renumber-and-repair pass - never edit ROADMAP alone. Commit the change atomically (protected-branch guard applies); never leave phase dirs and references out of sync. </process>
