# Update a context document

`PATCH /api/v1/context/{slug}`

## Request

- URL: `https://app.khotan.com/api/v1/context/{slug}`
- Auth: one of:
  - HTTP bearer
  - API key in header `x-api-key`

Updates the document's title, kind, content, description, tags, properties, and/or folder when expectedRevision matches the current revision. Properties replace the whole object; omit them to keep the current ones. Links are set separately. On mismatch, responds 409 revision_conflict with the current revision and updatedAt. The slug is immutable; title changes never re-slug. Limit violations respond 422 with the limit name, maximum, and submitted value.

## Path parameters

- `slug` string, required

## Request body

- object
  - `expectedRevision` integer, required: Required compare-and-swap token; a stale value returns 409 with the current revision and updatedAt.

  - `kind` 'instructions' | 'knowledge' | 'record': "instructions" = procedures to follow (SOPs, runbooks); "knowledge" = reference material (specs, policies); "record" = accounts of events (meeting notes, transcripts, interviews).
  - `content` string: Canonical raw markdown (max 256 KB, enforced by the domain layer).
  - `description` string, nullable: Pass null to clear the description.
  - `tags` string[]: Flat tag list; express hierarchy with naming conventions like "ops/runbook/deploy".
  - `properties` object: Structured facts beside the markdown: any JSON object.
