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 C, and why

mastermind-backup scanned grade C 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 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mastermind Backup

This skill is invoked directly via /mastermind-backup.


Inputs

  • brain_context: BRAIN CONTEXT block (injected by command, or loaded below if standalone)
  • org_name: org to back up or restore (optional for list; required for create/restore)
  • action: create | list | restore | delete
  • backup_file: path to backup archive (required for restore/delete; auto-selected for restore if omitted → latest)
  • backup_dir: directory to store backups (default: .monomind/backups)
  • include_state: whether to include runtime state file (default: false — state is ephemeral)
  • caller: command | master

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 — Ensure Backup Directory

backupDir="${backup_dir:-.monomind/backups}"
mkdir -p "$backupDir"

Step 2 — Execute Action

create

Create a compressed backup of all org data files:

[ -z "$org_name" ] && { echo "ERROR: --org required for create."; exit 1; }
orgFile=".monomind/orgs/${org_name}.json"
[ ! -f "$orgFile" ] && { echo "ERROR: Org '${org_name}' not found."; exit 1; }

timestamp=$(date +%Y%m%d-%H%M%S)
archiveName="${org_name}-${timestamp}.tar.gz"
archivePath="${backupDir}/${archiveName}"

# Collect files to back up
filesToBackup=""
for suffix in "" "-goals" "-routines" "-approvals" "-projects" "-members" "-issues" "-workspaces" "-worktrees" "-environments" "-plugins" "-adapters" "-threads" "-budgets" "-project-workspaces" "-approval-comments" "-bootstrap" "-secrets"; do
  f=".monomind/orgs/${org_name}${suffix}.json"
  [ -f "$f" ] && filesToBackup="$filesToBackup $f"
done

# Optionally include runtime state
if [ "${include_state:-false}" = "true" ]; then
  stateFile=".monomind/orgs/${org_name}-state.json"
  [ -f "$stateFile" ] && filesToBackup="$filesToBackup $stateFile"
fi

# Include recent activity (last 500 lines filtered by org)
eventsFile="data/mastermind-events.jsonl"
if [ -f "$eventsFile" ]; then
  tmpEvents=$(mktemp /tmp/backup-events-XXXXXX.jsonl)
  grep "\"org\":\"${org_name}\"" "$eventsFile" | tail -500 > "$tmpEvents" || true
  filesToBackup="$filesToBackup $tmpEvents"
fi

# Create archive
tar -czf "$archivePath" $filesToBackup 2>/dev/null
[ -n "$tmpEvents" ] && rm -f "$tmpEvents"

if [ -f "$archivePath" ]; then
  sizeKb=$(du -k "$archivePath" | awk '{print $1}')
  echo "Backup created: $archivePath (${sizeKb}KB)"
  echo "Files included: $(echo $filesToBackup | wc -w | tr -d ' ')"
else
  echo "ERROR: Failed to create backup archive."
  exit 1
fi

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.
