Every agent action carries heat.

Heat is the consequence an action carries if it goes wrong. Five dimensions decide how hot. Heat decides who pulls the trigger. One ladder, every function — the internal rubric that turns "should the agent be allowed to do this?" from a debate into a reading.

01 — The model

Five dimensions decide the heat.

Most teams argue about agent autonomy with vibes — "that feels risky." The ladder replaces vibes with five questions you can answer about any action, in any function. Score each from 0 (cool) to 4 (hot).

Can we take it back?

Reversibility

How hard is it to undo once done — a click, a cleanup job, or never?

0 · fully undoable 4 · permanent, unrecoverable
How far does it spread?

Blast radius

One record, one customer, one system — or everything at once?

0 · single item 4 · the whole estate
Who sees it?

Exposure

Does the output stay internal, reach one outsider, or go public?

0 · nobody outside the loop 4 · public, press, regulators
What does it bind us to?

Commitment

Does the action move money, make a promise, or sign the company's name?

0 · binds nothing 4 · legally / financially binding
What is it allowed to touch?

Authority

Read-only, a scratchpad, an internal system — or production and access control?

0 · read-only 4 · production & permissions

An action is as hot as its hottest dimension.

No averaging. Four cool dials never buy back one hot one — a perfectly reversible, narrow, internal action that signs a contract is still a contract. The hottest single dimension sets the band, and the band sets the control posture. This one rule is what stops "but it's mostly fine" from shipping a disaster.

Three dials are cool. The action is still HIGH — it leaves the building and asks for money.
02 — The ladder

Five bands, five control postures.

Heat is only useful if it changes something. Each band maps to exactly one answer to the only question that matters: who pulls the trigger? Tap a rung to open it.

03 — The forces

What moves an action up or down.

The same verb can live on three different rungs. Context is what moves it — these are the forces that push heat up, and the design moves that pull it back down. De-escalators are the real product: they're how you unlock autonomy safely instead of just forbidding things.

Escalators ↑

Each of these pushes one dimension toward red.

  • E1External audience — the output reaches a customer, partner, regulator, or the public. (Exposure)
  • E2Money moves — refunds, payments, discounts, payouts. (Commitment)
  • E3Legal signature — contracts, offers, filings, anything binding. (Commitment)
  • E4Production systems — live code, live data, live config. (Authority)
  • E5Identity & access — credentials, permissions, admin rights. (Authority)
  • E6Bulk scope — "all", "every", "entire". Scope multiplies whatever else is true. (Blast radius)

De-escalators ↓

Each of these is a design decision that cools a dimension.

  • D1Draft-only output — the agent produces, a human sends. Exposure drops to zero.
  • D2Sandboxed environment — staging, test data, dry runs. Authority drops to zero.
  • D3Undo window — delayed send, soft delete, versioned writes. Reversibility cools.
  • D4Hard caps — spend limits, rate limits, scope ceilings the agent cannot exceed. Commitment and blast cool.
  • D5Sampled review — a human audits a slice on cadence; trust is verified, not assumed.
  • D6Narrow allowlist — the agent touches named records, not classes of records. Blast cools.
04 — The action library

73 actions, nine functions, one spectrum.

Every function runs the same spectrum — from cool drafting to critical, irreversible action. Filter by function to see how the ladder lands in finance, engineering, support, HR, and beyond. Tap any action to drop it into Heat Check below.

Notice the pattern: cool drafting and recommending appears in every column, and critical, irreversible action caps every column. The function changes; the shape of the ladder does not.

05 — The rubric tool

Heat Check.

Type any agent action in plain language. Heat Check reads it across the five dimensions, places it on the ladder, and tells you the control posture it deserves. The guess isn't gospel — click any cell to correct it and watch the band move.

How to run this inside your team.

A heat model is only worth something when it changes what an agent is allowed to do unsupervised. Five steps, one working session, a living artifact.

List the verbs

Inventory every action your agents take or will take. Verbs and objects — "send quote", "update record" — not capabilities.

Score the five dials

Run each action through the five dimensions. Disagreement is signal: it means the action is underspecified.

Read the band

Hottest dimension sets the band. The band sets the posture. Write both next to every action — no exceptions, no averaging.

Design the cooling

For every action stuck at HIGH or CRITICAL, ask which de-escalator would cool it — drafts, sandboxes, caps, undo windows.

Review on incidents

The ladder is living policy. Every incident and every quarter, re-score. Promote actions that earned trust; demote ones that burned it.

Talk to auxfirst

Map your agents onto the ladder — in one working session.

auxfirst designs the trust layer for agentic systems — visible intent, evidence, autonomy boundaries, escalation paths, audit trails. We'll run your real action inventory through the ladder and hand you the rubric your team operates from.

Coming next — mapping these heat bands onto your real touchpoints. The ladder tells you how hot an action is; touchpoint mapping tells you where it happens.
