miro-code-spec

miro-code-spec is a skill for Claude Code, Codex from miroapp/miro-ai. It costs 57 tokens per session (4,498 once invoked), scanned A, original, MIT.

A workflow for copying specifications from a Miro board into local .miro/specs/ files. Specifications can include documents, diagrams, prototypes, tables, frames, and images.

In plain words
What is it for?
It helps extract all specification items from a board or retrieve one selected item using its Miro URL.
Why use it?
It keeps board information available during coding and planning without repeatedly retrieving it from Miro.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

miro-code-spec scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 470 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Extract Miro Specs

Extract specification content from a Miro board or item and save to .miro/specs/ so it can be referenced during planning and implementation without repeated API calls.

The user provides one URL: a board URL (extract all spec items) or an item URL with a moveToWidget / focusWidget parameter (extract that single item). Miro MCP must be available.

Workflow

1. Identify the URL from the user's request

  • If the user provided a Miro URL, use it.
  • If not, ask the user for one.

2. Determine URL Scope

Decide whether the user gave a board URL (extract every spec item on the board) or a single-item URL — i.e. a board URL with a moveToWidget or focusWidget query parameter naming one item. Pass the URL through to Miro MCP as-is — MCP handles the URL.

3. Check/Prepare Output Directory

  • Check if .miro/specs/ exists and has content.
  • If it has content, ask the user:
    • "The .miro/specs/ directory already contains files. What should I do?"
    • Options:
      • "Clean and extract fresh" — remove existing content
      • "Add to existing" — keep existing files
      • "Cancel" — abort operation
  • Create the directory structure if needed:
    .miro/specs/
    ├── documents/      # Markdown documents
    ├── diagrams/       # Diagram descriptions
    ├── prototypes/     # Containers (Markdown) and screens (HTML)
    ├── tables/         # Table JSON data
    ├── frames/         # Frame summaries
    ├── other/          # Unknown types (slides, etc.)
    └── images/         # Extracted images
    

4. Discover Items to Extract

For Board URLs:

  • Use the Miro MCP board-overview tool with the board URL.
  • Each returned item includes its type, URL (with moveToWidget parameter), and title.
  • Collect all items with their types, URLs, and titles for extraction.

For Item URLs:

  • Create a single-item URL list.

5. Create Tasks for Extraction (MANDATORY)

🚨 THIS STEP IS MANDATORY — DO NOT SKIP

Create an internal checklist item for EVERY item discovered so nothing is missed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
