MCP

• prompts/ capability — Agent Skills served over MCP. The MCP server now registers each of the seven DTPR Agent Skills (and the two shared reference documents) as named MCP prompts. Any MCP-aware client (Cursor, Continue, Cline, Claude Desktop, the Anthropic Agent SDK, custom clients) can list and load them via prompts/list + prompts/get without a Claude-specific install. Bundled at build time from plugin/dtpr/skills/ — single source of truth shared with the Claude plugin install path.
  • New CLI: pnpm --filter ./api bundle:skills regenerates api/src/mcp/prompts/skills.generated.ts.
  • Drift detection: pnpm test:plugin fails if a skill or reference exists in the plugin tree but not in the API bundle (or vice versa).
  • References: Prompts, Other harnesses.

Plugin

• Plugin v0.3.0 — symbol-design split + seven-skill studio. Symbol drafting moves out of dtpr-element-design into a dedicated dtpr-symbol-design skill that proposes three SVG variants per round with a local HTML preview. The plugin docs also pick up the previously-undocumented dtpr-translate skill from 0.2.1, so the public skill table now lists all seven peers. References: Skills, dtpr-symbol-design, dtpr-translate.

Icons

• Icon composition pipeline (#270) Shape × symbol × variant composition with default / dark / context-colored variants and the WCAG innerColor rule. Adds pre-baked R2 point-read with on-the-fly fallback. New REST routes: GET /api/v2/shapes/:shape.svg, GET /api/v2/schemas/:version/symbols/:symbol_id.svg, GET /api/v2/schemas/:version/elements/:element_id/icon[.<variant>].svg. New MCP tool: get_icon_url. References: Icon composition, REST icon routes.

Site

• dtpr.ai microsite placeholder (#271) Docus + Nuxt 4 skeleton deployed on Cloudflare Workers with a D1 binding for content queries. Minimal landing; no documentation yet.

@dtpr/ui

• Component library + render_datachain MCP tool (#267) Three subpath exports: @dtpr/ui/core (10 framework-neutral helpers), @dtpr/ui/vue (6 Vue 3 SFCs), @dtpr/ui/html (SSR via renderDatachainDocument). Default stylesheet wraps everything in @layer dtpr and exposes a full CSS custom-property token set. New MCP tool: render_datachain. New MCP resource: ui://dtpr/datachain/view.html (MCP Apps iframe handoff). References: Vue reference, Core reference, HTML SSR, Theming.

MCP

• Read path on Cloudflare Workers (#265) Hand-rolled JSON-RPC over HTTP handler (workerd nodejs_compat can't load the SDK's CJS Ajv dep). Supported methods: initialize, notifications/initialized, tools/list, tools/call, resources/list, resources/read, ping. Shared ok / err envelope with _meta.content_hash / _meta.version. Initial tools: list_schema_versions, get_schema, list_categories, list_elements, get_element, get_elements, validate_datachain. References: Connecting, Envelope.

REST v2

• api.dtpr.io/api/v2 read path (#265) Public, read-only JSON + SVG. Opaque cursor pagination (MAX_LIMIT = 200), field/locale projection, DTPR-Content-Hash + Cache-Control on version-scoped responses, static CORS allow-list. POST /schemas/:version/validate runs shape + semantic validation and always returns HTTP 200. References: REST v2, Pagination & fields, Errors.

API infrastructure

• Standalone API scaffold + AI content migration (#262) Extracts DTPR content from the v1 site into a standalone API workspace. Establishes the schema authoring flow and migrates the ai datachain type.
• CI: build @dtpr/ui + api/schema before typecheck (#268) Orders deploy workflows so generated types land before typecheck runs.
• Drafting CLI + preview deploys + Claude Code plugin (#266)

docs.dtpr.io

• Nuxt Studio with Google + GitHub OAuth (#269) Enables in-browser authoring for the existing v1 docs.
