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-monitor 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 Monitor

Invoked via mastermind:monitor or /mastermind-monitor.

A monitor is a named, forever-running task executor. It polls one or more task sources on a configurable interval, claims matching tasks, hands them off to a Claude agent for execution, posts back results as comments/status updates, and self-reschedules via ScheduleWakeup.


CLI Flags

--action   start | stop | pause | resume | status | list | add-source | tick
--name     monitor name (slug, e.g. "dev-agent")
--source   linear | github | monotask | filesystem
--interval poll interval in seconds (default: 120)
--user     filter by assignee username/email (can be repeated)
--state    filter by task state/status (can be repeated, default: open/todo)
--max-concurrent  max tasks in flight (default: 1)
--agent    agent type to execute tasks (default: coder)
--project  monotask project/board name, or gh repo (org/repo)
--team     Linear team ID or slug
--folder   filesystem folder path to watch (for source=filesystem)
--label    filter by label (can be repeated)
--caller   command | master (internal — skip brain load if "command")

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 — Resolve Monitor Config Directory

MONITOR_DIR=".monomind/monitor"
mkdir -p "$MONITOR_DIR"

Step 2 — Dispatch by Action

list (default when no --action)

echo "MONITORS"
echo "────────────────────────────────────────"
for f in "$MONITOR_DIR"/*.json; do
  [ -f "$f" ] || continue
  jq -r '
    "[\(.name)]  status=\(.status // "active")  interval=\(.poll_interval)s  agent=\(.agent_type)
    sources: \([(.sources // [])[].type] | join(", "))
    last_tick: \(.last_tick // "never")  tasks_done: \(.stats.done // 0)  tasks_failed: \(.stats.failed // 0)"
  ' "$f"
  echo ""
done

start

Creates a new monitor config and triggers the first tick.

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.
