Continuous scanner CI not detected

This plugin remains listed. Its overall trust score is reduced by 10% because security checks are not maintained in the source repository's CI.

Optional: maintain the scanner in the source repository's CI to receive the full trust score. Listing does not require that change.

README badge not detected

Plugin owners can add the HOL badge to the repository README from Guard Plugins. Distribution, not security evidence. It adds a 2% engagement adjustment to the overall trust score and never changes the security result.

Install guidance

Install in Claude Code

Claude Code plugin docs

Optional: install HOL Guard for Claude Code first, so it can check this plugin's tools on your machine before Claude Code uses them.

  1. 1

    Add the marketplace

    Run this inside a Claude Code session. It registers the marketplace manifest shipped at the repository root. If the repository ships none, add the generated entry from the Advanced section below first.

    claude code
  2. 2

    Install the plugin

    Installs the simpleviz entry from the simpleviz marketplace.

    claude code
  3. 3

    Scripted alternative

    Non-interactive equivalent for scripts and CI pipelines. Add --scope project to pin the install to one repository.

    shell
  4. 4

    Check it is installed

    Lists installed plugins. The entry should appear as enabled.

    shell

To remove it later, run claude plugin uninstall simpleviz@simpleviz.

Did setup work in Claude Code?

No setup reports for Claude Code yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.

Attested installs: Fewer than 10 attested installs of this plugin in week 2026-W44, so no number is shown. Counted from opt-in HOL Guard install reports, once per machine and runtime, and never mixed with the answers above. How install reports work.

    skills/simpleviz/SKILL.md

    Writes and checks simpleviz files — EDN graphs of nodes, edges and nested boxes, and markdown docs around them: slide decks, quiz and poll questions on slides, tables that calculate (formulas, also over CSV, JSON or EDN data), and bar, line and scatter charts of a table or data file — and serves, compares, exports and presents them with the simpleviz CLI. Use when creating or editing simpleviz graph EDN files or md docs, decks, quizzes, calculated tables or charts; visualizing an architecture or system diagram with simpleviz; making a talk, quiz or poll for a team, or a doc table or chart that sums, summarises or plots data, where simpleviz is in use; showing a proposed change as a before/after; or serving, forking and comparing graphs (bb serve, the simpleviz launcher, nodes/edges/boxes .edn files, exported PNGs/SVGs with embedded EDN).
