Swap subscriber SIM

subscriber.sim_swap
Telecom / Carrier ops
subscriber.sim_swap binds a subscriber's MSISDN to a new IMSI. Canonical account-takeover vector — never agent-callable.

Each tile is a domain — click in to see the agent tool calls that operators get to gate. Green-tier reads are authorized outright; Yellow-tier cards park for review; Red-tier cards are production-block cases that use an explicit review walkthrough in this safe demo.
Clavenar sits between an AI agent and its tools to allow, hold, or block actions before execution. These cards preview curated catalog dispositions; a live session creates safely scoped demo records.
Red cards describe the expected production block. The live walkthrough routes them through review so you can inspect the decision evidence without executing a destructive action.
Run the 90-second guided preview, then start a scoped live session.
The preview uses labeled sample evidence. A 2-hour live session lets you create your own scoped approvals and ledger rows.

Representative read-only requests pass without human review and land an authorized ledger row.
Reason: read-only CRM lookup with no export target.

Red
subscriber.sim_swap
Telecom / Carrier ops
subscriber.sim_swap binds a subscriber's MSISDN to a new IMSI. Canonical account-takeover vector — never agent-callable.
Red
subscriber.port_out
Telecom / Carrier ops
subscriber.port_out moves a number to another carrier. ATO + customer-loss vector — hard-deny.
Yellow
network.cdr_export
Telecom / Carrier ops
network.cdr_export ships 50,000 subscriber CDRs to an external bucket. Mass-surveillance shape — confirm warrant or compliance contract.
Yellow
subscriber.vm_password_reset
Telecom / Carrier ops
subscriber.vm_password_reset resets a subscriber's voicemail PIN. Known weak link in SIM-swap chains — confirm identity-verification.
Red
subscriber.e911_address
Telecom / Carrier ops
subscriber.e911_address updates the registered E911 address on a subscriber line. Life-safety implications if wrong — hard-deny.
Red
network.li_provision
Telecom / Carrier ops
network.li_provision taps a subscriber line. Requires a warrant + carrier-compliance review — never agent-callable.

Every agent is granted a tool-scope envelope. Clavenar reads the tamper-evident ledger to flag the scopes an agent never used, then lets an operator narrow that blast radius in one click — the change is chain-anchored and auditor-verifiable. A fleet gauge tracks the share of granted scope sitting unused.
Operators: open Registered agents
for the fleet gauge, or any agent's
detail page
with ?walkthrough=1 for the guided tour.
When an upstream tool reply carries sensitive data, the Egress
Inspector asks the policy engine what to do with each entity
type it located — deny,
sanitize,
pend, or
allow — from a Rego data document
(clavenar.egress.entity_actions).
The same response is blocked or redacted depending on that one map.
Upstream response
{"customer":"Ada Lovelace","ssn":"512-44-1729","status":"active"}
ssn = sanitize
{"customer":"Ada Lovelace","ssn":"[REDACTED:SSN]","status":"active"}
The SSN span is redacted in place and the rest of the response reaches the agent. An egress_sanitized row lands in the ledger.
ssn = deny
403 — upstream response withheld from the agent
Flip the SSN action to deny and the whole response is withheld; an egress_violation row records the block. Credentials deny by default.
Default action map
AWS_ACCESS_KEY→deny
PRIVATE_KEY→deny
API_KEY→deny
DB_CONNECTION→deny
SSN→sanitize
CREDIT_CARD→sanitize
EMAIL→sanitize
Sample shown for illustration — operators tune the map per deployment;
an unmapped type falls back to deny.
