Your Candle plan
The Candle Harness works on every Candle plan. Your plan sets what Candle and Hacc let your agents do, and the Candle Harness offers what your plan reaches. Candle’s Plans, pricing & limits is the source of truth for the plans themselves; this page says what each one means in the Candle Harness.

¹ Candle’s plan table lists Hacc’s tape and reads for every plan, but Hacc answers some of its stored reads, the tape’s history among them, only on Pro and Max (“Stored intelligence requires Pro or Max”). When it refuses one, the agent gets Hacc’s own words, and the doctor says the account is on Free rather than reporting a fault.
Everything else in the Candle Harness (cards, limits, paper trading, the kill switch, the tabs, every engine) is the same on every plan.
How the Candle Harness follows your plan
Section titled “How the Candle Harness follows your plan”- The agent is offered the tools your plan reaches, and told once which it doesn’t. Hacc learns your plan from Candle and refreshes it within about a minute of a change, and the Candle Harness reads it again every few minutes, so the next turn follows an upgrade.
- A read your plan doesn’t reach comes back in Hacc’s or Candle’s own words, rather than failing silently.
- Research says which of its reads your plan doesn’t reach, and shows the rest.
- A TEE wallet isn’t offered in setup on Free: it says a wallet of its own needs Pro or Max.
- Triggers say “Triggers need a Pro or Max plan” on Free, with a chip that types
candle plan buy, and nothing is read or fired. If your plan ends, every trigger is kept and held, and comes back on as it was when the plan returns. - Rules bots say “Bots need a Pro or Max plan” on Free, with the same chip, and nothing is proposed or entered. If your plan ends, every bot’s entries are held while its exits still sell what it holds, and it comes back on as it was when the plan returns.
- Code bots need Pro or Max too: on Free none runs or connects, and the Build tab can’t test or propose one, with the same chip. Its harness and your bots folder still work. If your plan ends, every code bot’s buys are held; its sells of its own, and the exits the core holds for it, still run.
candle-harness doctornames the plan the account is on, how many of Hacc’s tools it offers, and what Research can read.
Buying or renewing a plan
Section titled “Buying or renewing a plan”Ask the agent, or type candle plan buy pro (or max). It runs in the prompt pane, where the CLI shows the price and Candle’s terms, takes your typed confirm and asks for your vault passphrase, since it pays in USDC from a key in this machine’s vault. candle plan renew pays the next 30 days the same way, and candle plan status says when yours ends. Candle also takes a card; Plans, pricing & limits has the prices and how a change of plan is charged.
candle plan auto-renew on lets the CLI renew by itself in the 3 days before your plan ends, the next time you run a command at a terminal, up to the price you last confirmed. It still asks for your vault passphrase to pay, so it can do so in the prompt pane, before the step you approved. When it will, that step’s card says so first.
Every plan can buy a token that wasn’t launched on Candle, at its plan’s fee on a trade, and a sell always works.
Candle’s request limit
Section titled “Candle’s request limit”Candle limits each key’s requests a minute: 30 on Free, 300 on Pro and 600 on Max. The Candle Harness’s panes read in the background with your agents’ keys, the same keys their trades use. So:
- background reads use at most half of each key’s limit. When they’d go over, they’re read less often, and the pane’s title says so (“every 10 s (Candle’s limit)”);
- a trade or a turn never waits for a background read, and a few calls are always kept back for a card;
- a token’s reads and Candle’s lists go to the key with the most room.
On Free’s 30 a minute, a busy tab reads less often. Each agent’s key has its own limit, so a second agent adds room. The doctor shows each key’s use.
What Max adds
Section titled “What Max adds”On Max, Hacc’s strategy lab lets the agent save a strategy, backtest it against Hacc’s history, and replay it. A backtest describes the past: the Quant preset treats a good one as a reason to paper-trade, not to buy. Max also sees Hacc’s real-time book of a tracked wallet’s swaps and transfers, and has the lowest fee.
