# Creating Offers on angebote.lenne.tech This skill enables Claude Code to create, optimize, and manage business offers on the lenne.tech Offers platform via MCP tools. ## Gotchas - **Content block `order` values must be ascending without gaps** — Gaps in the sequence (e.g., `1, 3, 5`) cause rendering glitches on the offers frontend. When deleting a block, re-normalize remaining orders; when inserting, pick the next consecutive integer. The API does not validate this — the bug only surfaces client-side. - **`global-ref` block type is NOT listed in the standard MCP tool catalog** — It's created automatically by the `/offers:create` workflow when a block is promoted to the offers repository. Users attempting to use it directly via `create_offer` will get a schema error. The workflow guards this via the `@lenne.tech` git email check. - **OAuth session expires silently across sessions** — The `offers-api` and `offers-api-demo` MCP OAuth cookies are tied to the current Claude session and tracked per-server. Resuming an earlier offers session (via `--resume`) often hits a 401 on the first MCP call without a clear error. Re-authenticate by running a trivial MCP tool first. The first call against `offers-api-demo` triggers its own OAuth flow even if `offers-api` is already authenticated. - **`git config user.email` detection is fragile** — The reusable-block detection uses this to gate the lenne.tech-only flow. It fails for developers with a non-`@lenne.tech` email configured loca
