# Canva Design Editing

The canonical, safe way to apply edits to an existing Canva design. Every Canva skill that mutates a design should follow this exact protocol: **start a transaction → perform operations → commit (with approval)**. Changes are draft-only until committed and are PERMANENTLY LOST if not committed.

## The Transaction Protocol (always these steps, in order)

1. **`Canva:start-editing-transaction`** — pass the `design_id`. Remember the returned `transaction_id` and the `pages` array; both are required by later calls. ALWAYS show the user the thumbnail(s) returned here.
2. **`Canva:perform-editing-operations`** — apply edits. Pass the `transaction_id`, the `pages` array from the previous response, the `page_index` of the first page being changed, and an `operations` array. Batch multiple operations into a single call wherever possible.
3. **`Canva:commit-editing-transaction`** — save. See the approval gate below. After committing, the `transaction_id` is invalid; a new edit needs a new transaction.
4. **`Canva:cancel-editing-transaction`** — discard the draft instead of saving (e.g. the user rejects the preview, or you opened a transaction only to inspect the design).

## Capabilities — what the API CAN and CANNOT do

### CAN (operations on `perform-editing-operations`)
- **Text content**: `replace_text` (whole element), `find_and_replace_text` (substring)
- **Text formatting** (`format_text`): font size, weight (normal/bold), style (normal/italic), color, alignment, line height, underline, strikethrough, links, list level/marker
- **Media**: `update_fill` (replace image/video), `insert_fill` (add image/video), `delete_element`
- **Layout**: `position_element`, `resize_element`
- **Metadata**: `update_title`
- **Autofill mapping**: `update_autofill_field` (fixed-page designs only)

### CANNOT
- Change font **family/typeface** (only size, weight, style)
- Add **new text elements** (you can only insert media, not new text boxes)
- Change background colors or gradients
- Add, remove, or reorder pages/slides
- Modify animations, transitions, or element opacity (except on newly inserted fills)
- Group/ungroup elements, or restyle shapes (only text inside shapes is editable)

When a requested change is in the CANNOT list, tell the user it must be done manually in the Canva editor — don't attempt a workaround.

## Responsive pages — restricted operation set

Some pages come back marked `is_responsive: true`. On those pages, ONLY these operations are allowed:
`update_title`, `replace_text`, `update_fill`, `delete_element`, `find_and_replace_text`.

Before calling `perform-editing-operations`, check the `pages` array. If any operation targets a responsive page with an unsupported op (e.g. `format_text`, `position_element`, `resize_element`, `insert_fill`), do NOT make the call — tell the user that operation isn't supported on that page and offer an alternative.

## The commit approval gate (required)

`commit-editing-transaction` makes changes permanent. You MUST show the user exactly what changed (and the preview thumbnail) and get explicit approval before committing — e.g. "Here's the preview. Save these changes to your design?" Wait for a clear yes.

- Do NOT commit without approval.
- Do NOT tell the user changes are saved before the commit call has succeeded.
- After a successful commit, give the user a direct link to open the design in Canva.
- If a commit fails, all changes are lost — start a new transaction to retry.

> Note for composing skills: a skill that already collects a single up-front approval for a batch of changes (e.g. `canva-implement-feedback`) should treat that approval as covering the commit and NOT ask again. Follow that skill's own confirmation rules; the gate above is the default for direct, ad-hoc edits.

## Workflow

### Step 1: Resolve the design
- Short link (`canva.link/...`) → `Canva:resolve-shortlink` to get the URL.
- Full Canva URL → extract the design ID (the segment after `/design/`).
- Raw design ID (starts with `D`) → use directly; do NOT search.
- Nothing provided → ask for the design ID or link.

### Step 2: Start the transaction and inspect
Call `Canva:start-editing-transaction`. Show the thumbnail(s). Use the returned content to locate the exact `element_id`s you need to target. (If you only needed to look, call `cancel-editing-transaction` and stop.)

### Step 3: Build and perform operations
Translate the user's request into concrete operations. Confirm scope first when a `find_and_replace_text` string could match in multiple places or contexts — ask which instances they mean. Batch all operations into one `perform-editing-operations` call when you can.

### Step 4: Preview and commit
Show the resulting thumbnail and a plain-language list of what changed. Ask for approval, then `commit-editing-transaction`. Share the edit link.

## Rules
- Always remember and reuse the `transaction_id` and `pages` array within a transaction.
- Never leave a transaction uncommitted without telling the user their draft was discarded.
- For destructive ops (`delete_element`, large `find_and_replace_text`), confirm scope before performing.
- Prefer one batched `perform-editing-operations` call over many small ones.
