Miro Workflow Skill
Compose Miro boards from natural-language requests using the miro-mcp-server tools. The MCP exposes 91 atomic tools; this skill is the map.
Scope
If the request is a single-tool call ("create one sticky note"), a question about Miro the product, or read-only inspection ("what's on this board?"), exit and let Claude handle it directly. The skill's job is composition, not single-call wrapping. Routing happens via the description field, not this section.
The 5 workflows
Each workflow is a documented composition with default spatial values. Pick one based on intent:
| Workflow |
Trigger Phrases |
Detail File |
| Sprint Board |
"sprint planning", "sprint board", "sprint kickoff" |
[workflows/sprintboard.md](workflows/sprintboard.md) |
| Retrospective |
"retro", "retrospective", "what went well" |
[workflows/retrospective.md](workflows/retrospective.md) |
| Brainstorm |
"brainstorm", "ideation", "ideas around" |
[workflows/brainstorm.md](workflows/brainstorm.md) |
| Story Map |
"user story map", "story mapping", "user journey" |
[workflows/storymap.md](workflows/storymap.md) |
| Kanban |
"kanban", "task board", "workflow board" |
[workflows/kanban.md](workflows/kanban.md) |
If the request doesn't match any of these, fall back to direct tool calls and ask the user what layout they want.
Optional: seed boards
Before falling back to from-scratch construction, check if the user has imported a Miroverse template into their account that matches the requested workflow. See [seed-boards.md](references/seed-boards.md) for the lookup pattern. Seed boards are an optional power-user path; they produce more polished output but require one-time setup. The from-scratch workflows below work without any setup.
Workflow selection guide
Goal: track sprint work? → sprint_board (4 columns: Backlog, In Progress, Review, Done)
Goal: reflect on the team? → retrospective (3 frames: Went Well, Could Improve, Action Items)
Goal: generate ideas? → brainstorm (radial: central topic, 6 stickies in a ring)
Goal: map a product? → story_map (header row + tasks + release swimlanes)
Goal: ongoing task flow? → kanban (configurable column count)
Pick the workflow that matches the verb in the request (track, reflect, generate, map, manage). When in doubt, ask once.
Universal pre-flight (always run first)
Before any workflow:
- Call
mirolistboards to confirm the user's boards.
- If the user named an existing board, get its ID. If not, create a fresh board with
mirocreateboard.
- Save the
board_id for every subsequent call.
Do NOT skip pre-flight. Without board_id, every other call fails.
Spatial defaults (summary)
Full math in [spatial-defaults.md](references/spatial-defaults.md). Quick reference:
| Element |
Default size |
Default gap |
| Frame (column) |
800 × 600 |
50px between frames |
| Sticky note |
~200 × 200 (Miro auto-sizes) |
40px between stickies |
| Connector |
n/a |
uses item IDs, not coords |
| Title text |
font_size: 48 |
100px above first frame |
Origin (0, 0) is top-left in the board; the first frame sits at (0, 0) and successive frames stack to the right at x = previous_x + 800 + 50.
Color conventions
Full table in [color-conventions.md](references/color-conventions.md). Quick map:
| Color |
Used for |
| yellow |
default, neutral content, tasks |
| green |
positive (Went Well), Done, MVP |
| pink |
concerns (Could Improve), Review |
| blue |
In Progress, headers, activities |
| gray |
Backlog, future, low priority |
Match the prompt-defined colors in prompts/prompts.go for consistency with users who fire the MCP prompts directly.
Anti-patterns
These come up often. Avoid them.
- Stickies floating outside frames. Always pass
parent_id (the frame ID) when creating stickies inside a column. Otherwise the sticky lands at canvas root and looks orphaned.
- Wrong coordinate origin for parented items. When
parent_id is set, coordinates are frame-relative (NOT canvas-absolute). The frame's top-left is (0, 0) and the item's CENTER is placed at the given (x, y). So for an 800×600 frame, a sticky at (40, 40) will overflow the frame's left and top edges by ~half the sticky's size. To stay fully inside an 800×600 frame: x ∈ [100, 700], y ∈ [114, 486]. Center horizontally at x = 400.
- Frame
color requires CSS hex, not a named color. The Miro API returns 2.0703 invalid hex string for named colors ("green", "blue", etc.) on frames. Pass hex like "#A6E5BB". Stickies, in contrast, accept named values like "lightgreen", "yellow", "lightpink". See [color-conventions.md](references/color-conventions.md) for the named→hex translation table.
- Missing
boardid. Every create/update call needs it. Re-confirm after mirocreate_board.
- Sticky text > 280 chars. Miro truncates. Break into multiple stickies if longer.
- Hand-rolled flowchart connectors with raw shapes. Use
mirocreateflowchartshape (auto-sized for diagrams) instead of mirocreate_shape when building flowcharts.
- Bulk creates without ordering.
mirobulkcreate is fast but doesn't guarantee item order in the response. Don't assume index N = the Nth created item.
- Skipping the title text. Every workflow board gets a title at the top (font_size: 48). Without it, boards look unfinished.
Troubleshooting
Common errors when calling the miro-mcp-server tools, with cause and fix.
| Error |
Cause |
Fix |
401 Unauthorized |
MIROACCESSTOKEN missing or expired |
Tell the user to set the env var; restart the MCP host |
404 Not Found on board_id |
Wrong board ID, or board outside the user's team |
Re-run mirolistboards to confirm the ID; ask the user which team |
429 Too Many Requests |
Too many tool calls in a short window |
Use mirobulkcreate instead of individual calls; back off 5s and retry |
400 Bad Request on sticky create |
Invalid color name or parent_id not found |
Check color is one of: yellow, green, blue, pink, gray, orange, cyan; confirm parent frame exists before creating children |
| Connector create fails with "item not found" |
Bulk-create response order isn't guaranteed; the connector ran before the item ID was stable |
Always create items, await the response, collect IDs, THEN create connectors in a second pass |
| Sticky text shows "..." (truncated) |
Text exceeds Miro's ~280 char limit |
Split the content into multiple stickies; keep each under 280 chars |
| Frame title doesn't appear |
title was passed as empty string |
Always provide a title; Miro renders the title bar regardless |
| Items overlap visually |
Used canvas-absolute coords instead of frame-relative when parent_id was set |
Use (0, 0) to mean "frame's top-left" when parented; not the canvas origin |
| Board URL returns 403 |
Board is in a team the user isn't a member of |
Confirm the user's team via mirolistboards; recreate the board in their team |
If an error doesn't match anything above, return the raw error message to the user with the relevant tool name and the params you sent. Don't fabricate a diagnosis.
Bulk creation guidance
When a workflow needs more than ~5 items of the same type (e.g., 12 stickies in a sprint board), prefer mirobulkcreate over individual calls. Single round-trip, lower rate-limit pressure. Trade-off: response order isn't guaranteed, so don't rely on indices for downstream connector calls; use returned IDs.
For workflows that need connectors between items, create items first (collect IDs), then connectors in a second pass.
Common building blocks
All 5 workflows share these pieces:
Title
miro_create_text(board_id, content="<Workflow Name>", x=center, y=-100, font_size=48)
Centered above the first frame. Always present.
Column frames
miro_create_frame(board_id, title="<Column>", x=N*850, y=0, width=800, height=600, color="#A6E5BB")
N is the column index (0, 1, 2, ...). 850 = 800 frame + 50 gap. Frame color is a CSS hex string per anti-pattern #3 above; see [color-conventions.md](references/color-conventions.md) for the named-to-hex translation table.
Stickies inside a frame
miro_create_sticky(board_id, parent_id=<frame_id>, content="...", color="<color>", x=relative_x, y=relative_y)
parent_id is critical. Inside the frame, (0, 0) is the frame's top-left.
Connectors between items
miro_create_connector(board_id, start_item_id=<id_a>, end_item_id=<id_b>, shape="curved")
Use IDs from prior creation calls. Connectors don't need coordinates.
Output expectation
After completing any workflow, return:
- The board URL (formed from
board_id: https://miro.com/app/board/<id>/)
- A one-line summary: "Created [workflow name] with [N frames, M stickies, K connectors]"
- Any items skipped due to errors (with reason)
Never close out without the URL; that's the user's primary deliverable.
Pairing with MCP prompts
The miro-mcp-server ships 5 MCP prompts (create-sprint-board, create-retrospective, create-brainstorm, create-story-map, create-kanban) that produce procedural instructions identical to these workflows. The skill's job is to fire when the user phrases a request naturally (without invoking a slash-prompt). Both routes converge on the same compositions; that's intentional.
If the user explicitly fires /create-retrospective, defer to the prompt. The skill is for the implicit ask.
Best practices
✅ Do
- Run
mirolistboards first to confirm the user's workspace.
- Set
parent on stickies that belong inside frames.
- Use color conventions consistently (green = positive, pink = concern, etc.).
- Bulk-create when N ≥ 5 same-type items.
- Return the board URL at the end.
❌ Don't
- Skip the title text.
- Use canvas-absolute coordinates for items inside frames.
- Create connectors before the items they connect exist.
- Assume bulk-create response order.
- Fire 91 tool calls when 5 will do.
