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

kill-switch 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 2mo 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.

What it actually says

kill-switch

Tier: 3 (irreversible 🔴)
Trigger: Emergency only — REQUIRES owner confirmation
MCP Tool: run_algoclaw_skill("kill-switch", {"confirm": "FLATTEN_ALL", "reason": "..."})

What It Does

Emergency flatten of ALL positions across ALL configured brokers simultaneously. Stops all running bots. Posts full incident report to Slack.

Owner Verification

Skill REFUSES to execute unless:

  1. Caller Slack user ID matches OWNER_SLACK_USER_ID (set in .env)
  2. Explicit confirm string = "FLATTEN_ALL" passed in args
  3. Rate limit: max 1 execution per hour

Steps

  1. Verify owner ID and confirm string
  2. Log emergency event to algoclaw/state/kill_switch_log.jsonl
  3. Send pre-action alert: "KILL SWITCH ACTIVATED by {owner}" to #incident-response
  4. For each broker with open positions: a. Tradovate: cancel all orders → flatten all positions b. Alpaca: cancel all orders → flatten all positions c. OANDA: close all open trades
  5. Stop all bot processes (SIGTERM with 5s timeout then SIGKILL)
  6. Verify all positions at 0 via get_positions() for each broker
  7. Send post-action confirmation with list of closed positions + amounts
  8. Update AlgoClaw state: mode = "emergency_stopped"

Output Format

{
  "kill_switch_activated": true,
  "timestamp": "2026-04-08T14:30:00Z",
  "reason": "VIX spiked to 55, manual emergency",
  "actions": {
    "tradovate": {"positions_closed": 2, "orders_cancelled": 3},
    "alpaca": {"positions_closed": 0, "orders_cancelled": 0}
  },
  "bots_stopped": ["MNQ", "CL", "MES", "NQ"],
  "verification": {
    "tradovate_open_positions": 0,
    "alpaca_open_positions": 0
  },
  "incident_posted_to_slack": true
}

Recovery

After kill switch, system stays in emergency_stopped mode.
To resume: run_algoclaw_skill("resume-trading", {"confirm": "RESUME", "reason": "..."})

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.
