A settings tool for inspecting one installed plugin, changing its configuration, checking its health, and managing the files it may access.

In plain words
What is it for?
It helps view or change settings, grant or remove read or write access to paths, and check plugin status.
Why use it?
It makes plugin configuration and filesystem permissions visible instead of leaving them implicit. It also provides a place to inspect whether a plugin reports a healthy status.

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

mastermind-plugin-settings scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Mastermind Plugin Settings

This skill is invoked directly via /mastermind-plugin-settings.


Inputs

  • brain_context: BRAIN CONTEXT block (injected by command, or loaded below if standalone)
  • plugin_id: plugin id to manage (required)
  • org_name: org scope (optional — uses global registry if omitted)
  • action: show | config | status | grants | set-config | add-grant | remove-grant
  • config_key: config key to set (for set-config)
  • config_value: config value (for set-config)
  • grant_path: filesystem path to grant access to (for add-grant/remove-grant)
  • grant_access: read | write | readwrite (for add-grant, default: read)
  • caller: command | master

Plugin Configuration Model

{
  "id": "plugin-slug",
  "packageName": "@monomind/plugin-name",
  "status": "installed",
  "version": "1.2.0",
  "category": "monitoring",
  "config": {
    "apiKey": "***",
    "webhookUrl": "https://...",
    "customField": "value"
  },
  "grants": [
    { "path": "/tmp/plugin-data", "access": "readwrite" },
    { "path": "/project/logs", "access": "read" }
  ],
  "health": {
    "status": "ok",
    "lastCheck": "2026-01-01T00:00:00Z",
    "message": null
  }
}

Step 0 — Brain Load (standalone only)

If caller is not "command", load brain context following mastermind-protocol/SKILL.md Brain Load Procedure with namespace: ops.


Step 1 — Load Plugin Registry

registryFile=".monomind/plugins/registry.json"
[ ! -f "$registryFile" ] && { echo "ERROR: No plugin registry found. Install plugins via /mastermind-plugins."; exit 1; }

pluginDef=$(jq -r --arg id "$plugin_id" '(.plugins // [])[] | select(.id == $id)' "$registryFile")
[ -z "$pluginDef" ] && { echo "ERROR: Plugin '$plugin_id' not found. List plugins via /mastermind-plugins --action list."; exit 1; }

# Load org-level overrides if org_name specified
orgPluginsFile=""
if [ -n "$org_name" ]; then
  orgPluginsFile=".monomind/orgs/${org_name}-plugins.json"
  orgOverride=$([ -f "$orgPluginsFile" ] && jq -r --arg id "$plugin_id" '(.plugins // [])[] | select(.id == $id)' "$orgPluginsFile" || echo "")
