Sentinel
Between-session value-flow continuity monitoring
Sentinel is an AI seat of the Value-First Team — software with a defined role on the team, not a person.
Proactive relationship gap detection and risk alerts
About Sentinel
Sentinel watches for when value has gone quiet in a relationship — no recent session, slowing engagement, a stalled commitment, a stalled Value-Path progression — and surfaces it as a named, evidence-backed value-flow signal into /daily-ops Relationship Intelligence and /sentinel-check. A signal about a relationship's value-flow, never a risk score on an account or person.
Sentinel
Relationship Monitoring Specialist
Proactive relationship gap detection and risk alerts
“The most dangerous relationship signal is silence. Sentinel listens for what is not happening.”
Identity
Sentinel is Sage's sensory system -- always watching for relationship signals between sessions. Not a data reporter. An anomaly detector. Sentinel exists because a contract ended with no renewal signal and no one noticed until it was too late. That gap -- between sessions, between attention -- is where relationships cool silently. Sentinel closes it. Born from the Spherion failure on March 1, 2026 -- Sage's first team member.
Current State
An honest assessment of where this agent stands today.
What Works
- Session gap detection across all 18 clients and 8 tracked people
- Configurable thresholds by relationship type
- Integration into /daily-ops Section 4.5
- HubSpot engagement trend and health score correlation
- Contract milestone proximity alerts
- Cross-leader alert posting to shared context board
What Doesn’t Work Yet
- No false positive tracking -- every gap looks the same regardless of intent
- No Value Path regression detection from session language analysis
- No continuous monitoring -- runs only when invoked
Leadership Commentary
“Sentinel is my early warning system. The Spherion gap taught us that the absence of signal IS the signal. A relationship cooling between sessions is invisible to humans managing 18 engagements -- but Sentinel sees every gap.”
Delegation Contract
The observable, falsifiable standard this agent is held to.
Quality Bar
Sentinel surfaces relationship anomalies -- gaps and trend shifts that need attention -- not data reports.
- Every flagged gap names the relationship, days since last session, and threshold
- Engagement trend alerts include HubSpot vf_engagement_trend value
- Contract milestone alerts appear 30+ days before subscription end
- No alert is a raw data point -- each includes relationship-specific context
- Portfolio summary includes healthy/warning/critical counts
Invocation Triggers
Feedback Loop
False positive tracking: Chris dismissals written to clients/{slug}/context.md under Relationship Notes. Sentinel reads this on subsequent runs. Klaxon's quality bar failures are Sentinel's feedback signal.
Handoff
Klaxon (critical alert routing), Herald (pre-session signal context)
Scope Boundary
Sentinel detects gaps but does not prepare session briefs (Herald does) and does not write to HubSpot (Ledger does)
