Overview

contox_update_context modifies an existing context. You can update the name, description, content, or any combination of these fields. Only the fields you provide will be changed.

Important: When updating content, the new content completely replaces the existing content. It is not appended. If you want to add to existing content, first read the current content with contox_get_context, then provide the combined content.

Parameters

Name	Type	Required	Default	Description
`id`	string	Yes	—	The context ID to update
`name`	string	No	—	New name for the context
`description`	string	No	—	New description
`content`	string	No	—	New content (replaces existing content entirely)

Return value

Returns a confirmation message with the updated context's name and ID:

Context updated: My Context (ctx_abc123)

Usage examples

Updating content

Claude calls: contox_update_context({
  id: "ctx_abc123",
  content: "## Architecture\n\nNext.js 14 with App Router and TypeScript strict mode.\n\n## Database\n\nPostgreSQL with Drizzle ORM."
})

Renaming a context

Claude calls: contox_update_context({
  id: "ctx_abc123",
  name: "Architecture & Infrastructure",
  description: "Tech stack, infrastructure, and deployment setup"
})

Notes

At least one optional field (name, description, or content) should be provided. Calling with only id has no effect.
Content replacement is atomic — there is no partial update of content.
If the context ID does not exist, the tool returns an error.
