Payment operations / controlled autonomy
Clean up today’s
payment problems.
Delegate outcomes, not unlimited access. Sloth equips autonomous agents with narrow baseline tools, surfacing temporary financial capabilities only through verified, human-approved grants.
Autonomous simulation mode active for standard browsers.

Operator Intent
“Clean up today’s payment problems. Only bother me when you actually need my authority.”
01 Agent investigation
duplicate charges confirmed
retries resolved safely
02 Scoped runtime enforcement & boundary testing
Awaiting capability grant: no financial mutation capability is registered. Approve a request above to activate boundary testing, the TTL countdown, and execution controls.
- Run is waiting for your intent.
Dynamic Capability Architecture
Authority that scales with trust.
Narrow by default, temporary when escalated, and enforced inside the tool handler — not only in the UI.
Phase 01 / Least Privilege
Narrow Baseline Discovery
The agent begins with read-only inspection tools and pre-authorized idempotent retries. Financial mutations do not exist in the browser context.

Phase 02 / Hard Boundary
Just-in-Time Authority Request
When duplicate charges are confirmed, the agent halts at the boundary and calls request_capability. The operator approves or limits an immutable grant.
request_capability({
capability: "refund_scoped_transactions",
scope: {
transactions: ["TX-48", "TX-72", "TX-184"],
maxAmount: 184,
maxTotalAmount: 304
},
reason: "Confirmed duplicate charges"
})● Human Governed · Scope Locked
Phase 03 / Deterministic Safety
In-Tool Enforcement & Expiry
Scope constraints are checked inside the tool handler, returning structured violations. The capability disappears when consumed, denied, or expired.
