01 / CORE LOOP

The Agent Cycle

Every action follows a four-phase reasoning loop. The agent never acts blindly - it perceives context, reasons through options, executes with precision, then learns from the outcome.

Perceive

Phase 1

Ingest CRM data, monitor email replies, parse market signals. The agent builds a real-time picture of every lead's state before making any decision.

CRM sync Email parsing Signal detection

Reason

Phase 2

LLM evaluates lead quality, determines optimal next action, and cross-references past interactions. Every decision has a reasoning chain.

Lead scoring Context recall Action planning

Act

Phase 3

Send personalized outreach, schedule follow-ups, update CRM records, or flag for human review. Each action is logged with full context.

Email send CRM update Escalation

Reflect

Phase 4

Log outcomes to the audit trail, update lead scoring models, and refine approach based on conversion data. The agent gets smarter with every cycle.

Outcome logging Score update Approach tuning
Continuous loop - every lead, every interaction, every day
02 / TOOL REGISTRY

Agent Capabilities

The agent's toolbox. Each tool is a discrete capability with defined inputs, outputs, and permissions. The agent selects and chains tools based on its reasoning.

PRIMARY

CRM Lookup

Query lead data, interaction history, and scoring. Hydrates the agent's context before any outreach decision. Supports fuzzy search, timeline queries, and segment filtering.

in: lead_id | query out: LeadProfile
CORE

Email Composer

Generate personalized outreach calibrated to lead profile, stage, and lending product interest.

in: LeadProfile, template out: EmailDraft
CORE

Email Sender

SMTP integration with built-in rate limiting, domain throttling, and deliverability monitoring.

in: EmailDraft, config out: SendResult
SUPPORT

Calendar Scheduler

Book follow-ups and meetings. Integrates with sales team calendars for availability-aware scheduling.

in: lead_id, action out: ScheduleEvent
ML

Lead Scorer

ML-based qualification combining firmographic data, behavioral signals, and historical conversion patterns.

in: LeadProfile out: Score (0-100)

Human Escalation

SAFETY-CRITICAL

Flag for manual review when confidence is low, lead value exceeds threshold, complaint is detected, or regulatory sensitivity is flagged. The human always has final say.

triggers: high-value lead, complaint, low confidence, regulatory flag out: EscalationTicket
03 / GUARDRAILS

Safety Architecture

Autonomy without guardrails is a liability. Every safety mechanism is enforced at the infrastructure level - not just in the prompt.

ACTIVE

PII Protection

Auto-redact SSN, account numbers, and sensitive financial data from all agent logs and reasoning traces. PII never enters the LLM context.

SSN detection: regex + NER Account masking: last-4 only Log retention: redacted-only
ACTIVE

Regulatory Compliance

CAN-SPAM compliance baked in. Opt-out handling is automatic. Lending-specific regulations (TILA, RESPA, ECOA) enforced through pre-send validation.

Unsubscribe: auto-honored Required disclosures: template-enforced Fair lending: bias monitoring
TUNABLE

Rate Limits

Configurable sending velocity with soft and hard caps. Per-domain throttling prevents reputation damage. Automatic backoff on bounce signals.

50
daily soft cap
100
daily hard cap
5
per domain/hr
2%

ENFORCED

Human-in-the-Loop

Escalation triggers are non-negotiable. The agent cannot override human review requirements regardless of confidence score.

High-value leads (portfolio > $5M) MANDATORY REVIEW
Complaint or negative sentiment detected MANDATORY REVIEW
Classification confidence below 70% FLAGGED
Regulatory sensitivity keywords FLAGGED
ACTIVE

Audit Trail

Every agent action logged with full reasoning chain, tool inputs/outputs, and decision metadata. Immutable append-only log with timestamp and session context. Queryable for compliance review.

04 / TRACE

Agent in Action

A real-time reasoning trace from a sample lead interaction. Every step is observable, every decision is justified, every action is logged.
