# Limits

Every limit here reports itself rather than failing silently. These are the numbers to plan around.

## Every limit

| **Limit**                                | **Value**                                | **What happens**                                                                                                                                                                                            |
| ---------------------------------------- | ---------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Large-document scroll mode               | 500,000 characters                       | Past this the document macro shows '⚠️ Large content detected. Rendering in scrollable mode.' and renders inside a fixed 1200px-high scroll box instead of inline.                                          |
| Virtualised rendering threshold          | 500,000 chars ; 1,000,000 chars (large p | Above the threshold the document is chunked (400 lines or 60,000 characters per chunk, fences kept intact) and only visible chunks are rendered.                                                            |
| MCP / Rovo document size cap             | 512 KB (524,288 characters)              | Creating or updating a markdown asset through the Capable tools refuses (rather than truncates) anything larger, with a message telling the caller to split it.                                             |
| AI diagram repairs per generation        | 3                                        | Only the first three fenced diagram blocks in a generated document are validated and repaired; anything beyond that, and any language outside the seven repairable ones, passes through verbatim.           |
| Macro title and description input length | 50 characters each                       | The macro config's 'Markdown title' and 'Markdown description' fields and the from-scratch editor's title field all stop at 50 characters.                                                                  |
| Library import truncation                | Title 128 characters, description 250 ch | Dragging page-owned markdown into the template library silently truncates the copied title and description.                                                                                                 |
| Version history entry limit              | 50                                       | Beyond 50 versions the panel shows 'Limited to the last 50 entries'.                                                                                                                                        |
| Version list de-duplication window       | 15 seconds                               | Versions saved within 15 seconds of the previous shown entry are hidden from the list, so rapid auto-saves do not flood it (migration-era versions are exempt).                                             |
| Image load timeout                       | 15 seconds                               | An image inside markdown that has not loaded in 15 seconds is replaced with '\[Image load timed out: …\]'.                                                                                                  |
| New-macro retry window                   | 10 retries at 15 seconds ≈ 2.5 minutes   | When an asset should exist but has not indexed yet, a freshly inserted document macro retries the fetch on a 15-second timer up to 10 times before giving up. Legitimately-unconfigured macros do not poll. |
| New-template catalogue polling           | 8 attempts, backoff up to 8 seconds each | After creating a template the app polls for the Confluence-side listing to include it, so a new template can take several seconds to appear.                                                                |

## A few things worth knowing

* A limit that is reached is reported in the interface, not in a log you have to find.
* Limits are per site or per tenant depending on the limit. The table says which.
* Edition can change some of these.
