Every case has three content surfaces:

Surface	Purpose	Persistence
Description	The primary narrative area at the top of every case. Always visible, always first in the table of contents.	Durable — meant to be the source of truth.
Case blocks	Discrete, reorderable sections below the description. Each block has its own title, color, type, and visibility settings.	Durable — structured evidence, checklists, files, linked cases, and more.
Comments	Real-time discussion in the activity timeline.	Durable — but conversational. Decisions from comments should be promoted into the description or a block.

All three surfaces share the same rich-text editor powered by CommonMark and GFM formatting, slash commands (`/`), and @mentions. ### How content flows into a case Content can be authored in several ways: - **Manually** — type directly into the description, a block, or the comment composer. - **Via a case template** — pre-populate descriptions and blocks when a case is created. - **Via story automation** — use the Cases API or action templates to create and update descriptions, blocks, and comments programmatically. - **Via paste** — paste text, images, or case URLs directly into any rich-text surface. ### Typical workflow 1. A case is created (manually or by a story) and the description is populated with initial context. 2. Blocks are added to organize evidence, remediation steps, timelines, or other structured sections. 3. Teammates collaborate via comments and @mentions in the activity timeline. 4. As the investigation progresses, key decisions from comments are promoted into the description or blocks. 5. The case is exported (PDF) or referenced in dashboards and records. ### Content limits (summary)
