Update a context

PUT /contexts/{slug}

• slug (path, string, required) — Context slug or UUID.
• X-Pinecone-Api-Version (header, string) — Date-based contract version, echoed back on the same header. Omit for the default (2026-07); send unstable for the in-development surface. An unrecognized value is rejected with 400 unsupported_api_version.

• slug (body, string) — Renames the context. Must stay unique within the project.
• name (body, string) — New display name.
• description (body, string) — New summary. Empty string clears it.
• guide (body, string) — New standing instructions. Empty string clears them.
• manifest (body, object) — The document that drives curate and search. Sparse: every field is optional and an omitted one falls back to its default, so absent fields are omitted rather than nulled. A change reaches the index on the next curate; rebuilding what is already indexed needs a forced one.

• 200 — The updated context
• 400 — Invalid request
• 404 — Not found
• 409 — Slug conflict
