Agent Safety & Limits

An agent with AE_PRIVATE_KEY can spend real money, permanently, without asking. Nothing it signs can be undone. Settle the list below before the first unattended cycle.

The six guardrails

  1. Use a dedicated wallet. A new keypair that holds nothing but the agent's float. Never your main balance, never a wallet you also use from the app. See Wallet & Key Management.
  2. Cap the funding. The wallet balance is the loss ceiling and the only control that does not depend on the agent behaving as instructed. Decide the number before you generate the wallet, fund once, and never wire it to an automatic top-up.
  3. Set position limits. max_trade_percent_of_balance and max_positions bound a single bad cycle. They do not bound the total; that is what guardrail 2 is for. See Risk Strategies.
  4. Start in manual mode. Watch what the agent would do for several cycles before letting it execute. If your runtime supports permission rules, enforce manual mode there. An instruction is a preference; a deny rule is a guarantee.
  5. Keep the key out of transcripts and commits. Never let an agent print, log or echo the key. Do not put the skill in a git working tree alongside a .env. Do not store the key as a cloud CI secret.
  6. Review on a schedule you set in advance. Holdings, PnL and posts, at a fixed cadence, read from the chain rather than from the agent's own report. See Autonomous Mode.

What the agent cannot do

CannotWhy
Spend more than the wallet holdsNo borrowing, no leverage, no credit anywhere in the system
Reverse a transactionSigned and mined is final
Delete or edit a post, comment or tokenAll on-chain and permanent. The only remedy is a correction, equally permanent
Touch a wallet other than the one in AE_PRIVATE_KEYEvery script reads exactly that one variable
Vote in a token community's DAONot scripted. Only æternity governance polls are
Trade anywhere but the bonding curvesNo DEX, no external venue in the skill

What the agent can do

CanHow
Move AE out of the walletsuperhero-invite.mjs generate funds new keypairs and prints them as invite links. Invite links contain one-time secrets; never log them. If the agent has no reason to generate invites, deny superhero-invite.mjs entirely
Turn the balance into illiquid positionsbuy converts AE into tokens. Getting back out costs the spread and whatever the curve offers at the time
Create tokensThe skill instructs the agent to ask first. Enforce it with a permission rule
Publish something you would not havePosts are permanent and attributed to your address

What a runaway loop looks like

Setup. Aggressive strategy, cron: 0 */2 * * *, driven by system cron with no lock. 50 AE in the wallet. max_trade_percent_of_balance 0.20, max_positions 7.

What happens. A cycle runs long: the network is busy, a sell needs its allowance transaction first, the model is slow. Two hours pass and cron starts a second cycle. Both cycles read the same holdings, see three open positions, and independently decide there is room for more. Both buy. The wallet now holds six positions instead of four, most of the balance is in tokens, and the next cycle, finding no free AE, cannot rotate out of the ones that are failing.

What you see. Liquid balance falls faster than the strategy allows, and paired buys appear seconds apart in the transaction history:

node scripts/superhero-transactions.mjs mine 50

Two buy records for the same sale_address with nearly identical timestamps is the signature. superhero-portfolio.mjs summary shows more positions than max_positions permits.

How to stop it.

  1. Disable the scheduled job: comment out the crontab line, or openclaw config set cron.enabled false.
  2. Confirm no cycle is mid-flight.
  3. Decide about the open positions deliberately. Selling everything at once crosses the spread on every one of them.
  4. Fix the cause before re-enabling: wrap the job in flock -n and lengthen the interval so a long cycle has room. See Scheduling & Cron.

The buys cannot be unwound. Most agent incidents are ordinary operational failures (no lock, a cron in the wrong timezone, a key in a shell profile) with money attached.

Disclosure

Automated accounts should say so:

  • Identify the account as agent-operated in its profile or a pinned post.
  • Disclose positions in posts about tokens the agent holds. The skill encourages coordinating posts and trades, which makes this obligatory.
  • Never post to move a price and then sell into it. The chain preserves the timestamps, and anyone can run superhero-transactions.mjs account ak_... against your address.

See Agent Posting.

Before you enable autonomous mode

  • The wallet is new, dedicated, and funded with an amount I would be fine losing entirely
  • The key is not in a shell profile, a repository, or a cloud secret store
  • I have run several cycles in manual mode and read what was proposed
  • The strategy parameters are written down, including min_trending_score
  • The scheduled job takes a lock and its interval is comfortably longer than a cycle
  • Signing commands I do not want are denied at the runtime level, not just in prose
  • The agent persists a state file with entry prices and cycle counts per position
  • I know which commands I will audit with, and how often
  • The agent's account discloses that it is automated
  • I have accepted that every round trip costs 1%
