The file

We split this skill into the rules it gives an agent

7 rules. 0 are common, 3 are distinctive, and 4 are very specific to this project.

  • 0

    Common

    Most of the 41 edited versions we read keep these.

  • 3

    Distinctive

    This author's own choices. Worth a look.

  • 4

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Use one sample in that file (minimal default).

    line 58
  2. Distinctive:

    Prefer ≤ ~12 primary elements unless the user asked for more.

    line 62
  3. Very specific:

    Use cloud mode only when one of these holds: the user asks to save, keep, or update a cloud diagram, or to search cloud diagrams.

    line 69
  4. Very specific:

    If login fails or times out, use short-link mode and tell the user why.

    line 71
  5. Distinctive:

    If the user pastes a viewer URL, load pointers.

    line 72
  6. Very specific:

    No scene to draw (and not an update): show https://luluboard.app/ and stop.

    line 78
  7. Very specific:

    Write the Source to .cache/mermaid/<name>.mmd.

    line 79

“Common” is measured: kept by at least 6 in 10 of the 41 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

mermaid

List the catalog, or author an open catalog type and open it on the public viewer. Done when the list is shown, or a tool url is shown.

Syntax

Author Mermaid 12.1.0 built-in syntax. Drawer renders flowchart with Pele 1.7.0 and mindmap with a custom SVG pipeline, not Mermaid.js.

CLI

The shared CLI reference defines $BOARD_CLI.

  1. Load cli before the first $BOARD_CLI call of a session.

References

Load only what the current interface needs.

  1. list — load catalog only.
  2. route — after an open type is chosen, load that one file from catalog.

Interfaces

Two entries. Do not author during list.

  1. list — slash list, or the ask is which types exist. Load catalog. Show the class table, including Open. Stop.
  2. route — any draw ask. Pick exactly one catalog type. If it is not open, say it is not open, then stop. If it is open, load only that file. Author. Preview.

Route

The catalog is the type boundary. Open is flowchart (flowchart / graph), mindmap, and the Design group (sequence, class, state, er, requirement, c4, usecase, eventmodeling, railroad). flowchart-elk is the flowchart type.

  1. A named type or alias wins.
  2. Else pick the type that matches what must be visible.
  3. Two fit → pick one; do not stop to ask.
  4. None fit → ask one line, then stop.
  5. A closed type → say it is not open, then stop. Do not author.
  6. Source already in hand and the ask is to publish it → skip Author; run the Short link flow.

Author

What to write, after the open type file is loaded.

  1. Use one sample in that file (minimal default). Flowchart: one edge-meaning category. Mindmap: one root, indented branches. Design: Pele preview; Title and Source.
  2. Replace labels; keep the sample's node and edge kinds.
  3. Prefer ≤ ~12 primary elements unless the user asked for more.
  4. Mint without %% style. On update, leave those lines unchanged.

Mode

Pick short link or cloud. Short link is the default.

  1. Use cloud mode only when one of these holds: the user asks to save, keep, or update a cloud diagram, or to search cloud diagrams; the user pastes a #b: link; this session already created the diagram in cloud mode. Load cloud.
  2. Otherwise use short-link mode.
  3. If login fails or times out, use short-link mode and tell the user why.
  4. If the user pastes a viewer URL, load pointers.

Short link flow

Publish unsigned.

  1. No scene to draw (and not an update): show https://luluboard.app/ and stop.
  2. Write the Source to .cache/mermaid/<name>.mmd. <name> is a short English name for the diagram.
  3. Run $BOARD_CLI preview-diagram --file <file>.
  4. Show only the url field and stop.
  5. To change, edit the file and publish again. That creates a new short url.
  6. To keep, use cloud mode (#b:).

Open wording

Show the url. One line.

Boundaries

  1. CLI contract: $BOARD_CLI --help.
  2. CLI success completes the skill; do not open the URL, drive the viewer, or screenshot the layout unless the user explicitly requests visual verification.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
