 # Changelog
 
+## [0.14.3.0] - 2026-03-30 — Ship Idempotency + Skill Prefix Fix
+
+Re-running `/ship` after a failed push or PR creation no longer double-bumps your version or duplicates your CHANGELOG. And if you use `--prefix` mode, your skill names actually work now.
+
+### Fixed
+
+- **`/ship` is now idempotent (#649).** If push succeeds but PR creation fails (API outage, rate limit), re-running `/ship` detects the already-bumped VERSION, skips the push if already up to date, and updates the existing PR body instead of creating a duplicate. The CHANGELOG step was already idempotent by design ("replace with unified entry"), so no guard needed there.
+- **Skill prefix actually patches `name:` in SKILL.md (#620, #578).** `./setup --prefix` and `gstack-relink` now patch the `name:` field in each skill's SKILL.md frontmatter to match the prefix setting. Previously, symlinks were prefixed but Claude Code read the unprefixed `name:` field and ignored the prefix entirely. Edge cases handled: `gstack-upgrade` not double-prefixed, root `gstack` skill never prefixed, prefix removal restores original names.
+- **`gen-skill-docs` warns when prefix patches need re-applying.** After regenerating SKILL.md files, if `skill_prefix: true` is set in config, a warning reminds you to run `gstack-relink`.
+
+### Added
+
+- **`bin/gstack-patch-names` shared helper.** DRY extraction of the name-patching logic used by both `setup` and `gstack-relink`. Handles all edge cases (no frontmatter, already-prefixed, inherently-prefixed dirs) with portable `mktemp + mv` sed.
+
+### For contributors
+
+- 4 unit tests for name: patching in `relink.test.ts`
+- 2 tests for gen-skill-docs prefix warning
+- 1 E2E test for ship idempotency (periodic tier)
+- Updated `setupMockInstall` to write SKILL.md with proper frontmatter
+
 ## [0.14.2.0] - 2026-03-30 — Sidebar CSS Inspector + Per-Tab Agents
 
 The sidebar is now a visual design tool. Pick any element on the page and see the full CSS rule cascade, box model, and computed styles right in the Side Panel. Edit styles live and see changes instantly. Each browser tab gets its own independent agent, so you can work on multiple pages simultaneously without cross-talk. Cleanup is LLM-powered... the agent snapshots the page, understands it semantically, and removes the junk while keeping the site's identity.
