User-facing changes, newest first. See git log for the full commit history.

Unreleased

Platform

• Public HTTP API — POST /api/validate, POST /api/generate,
  GET /api/import, GET /api/card.svg. Documented at
  /api with curl examples.
• X-RateLimit-* response headers on every public endpoint so callers
  can back off before hitting 429s.
• Sitemap at /sitemap.xml enumerating the landing, API docs, design
  showcase, and every template slug.
• Branded error pages with status-aware copy for 404 / 429 / 5xx.

Builder

• ⌘K command palette — tab jumps, download, share, duplicate, focus
  chat, validation sheet, shortcuts help, template loading, and per-skill
  / per-agent jump entries.
• Validation sheet — click the footer status row to see the full
  grouped list of errors + warnings; click any row to jump to the owning
  tab.
• Keyboard shortcuts — ⌘D download, ⌘1–6 tab nav, / focus chat,
  ? help overlay, 1–9 chat choice picker.
• Header metadata strip — live "N skills · N agents · N hooks · N MCP
  · NN KB" counts plus a "Saved Xs ago" indicator.
• Reorder skills / agents with ↑ / ↓ buttons and moveSkill /
  moveAgent store helpers.
• Edit / Preview toggle on both the SKILL.md body and agent system
  prompt textareas, using the shared sanitised Markdown renderer.
• Theme toggle — Auto / Light / Dark, persisted to localStorage,
  overrides the OS preference.
• Duplicate plugin from the builder header (owners only; mirrors the
  existing Fork for non-owners).
• Copy plugin.json and Copy Markdown digest quick actions in
  Overview.

Import / export

• Plugin ZIP import — drop a .zip on the landing page (drag-drop
  anywhere or use the file picker) and the builder reconstructs the full
  spec, lossy on unknown frontmatter but tolerant of flat-root and
  wrapper-folder layouts.
• GitHub URL import — paste owner/repo or a github.com URL; the
  /api/import proxy fetches the codeload tarball and the browser feeds
  it into the same importer.
• Dynamic OG install card at /api/card.svg with plugin name,
  description, platform pills, and 1h edge cache.
• Template preview pages advertise the dynamic card via og:image
  and Twitter card meta.
• Drafts dashboard at /drafts with a filter input and
  delete-from-dashboard action.

Spec coverage

• Multi-platform targets: Claude Code (default) and Codex
  (config.toml, .agents/plugins/marketplace.json) via the
  PluginTarget abstraction, plus an all bundle.
• Agent frontmatter: all 9 plugin-spec fields — model, effort,
  max-turns, tools allowlist / disallowedTools denylist, skills access,
  memory, background, isolation — with exclusivity + reference
  validation.
• Hooks: all 26 lifecycle events (grouped selector) and all 4 hook
  types (command / http / prompt / agent) with type-aware inputs and
  integrity checks.
• userConfig editor (key / description / sensitive) and
  settings.json default-agent activation.
• Manifest metadata: homepage, repository, keywords, author
  name/email/url.
• .claude-plugin/marketplace.json and Codex-format marketplace
  manifests emitted in every ZIP.
• Remaining component types: LSP servers, channels (bound to an MCP
  server), bin/ executables, legacy commands/, output-styles/.
• Starter scaffolds — three opinionated starters (code-review,
  summarise, pre-deploy-check) in the "+ From template" menu on the
  Skills panel.

Landing

• Hero redesign — wider input, animated typewriter placeholder
  cycling six prompts, platform badges (Claude Code + Codex), GitHub
  import chip.
• Before / After demo with a Run it live button that streams
  real Claude output through /api/demo-compare.
