# Cx Alert Monitor Spec > Use to turn a one-off support search into a standing monitor or alert that stays useful instead of being muted within a fortnight. Trigger for "alert me when a customer mentions X", "notify the team when complaints spike", "keep watching for this", "set up a daily monitor for", turning an ad-hoc sweep into something recurring, or an existing alert nobody reads any more. - Skill: `rulebase-co/cx-alert-monitor-spec` (Agent Skill) - Install (CLI): `npx skillmds add rulebase-co/cx-alert-monitor-spec` - Raw SKILL.md: https://api.skillmd.com/api/skills/rulebase-co/cx-alert-monitor-spec/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: rulebase-co (https://skillmd.com/u/rulebase-co) - Updated: 2026-08-19 - Page: https://skillmd.com/skills/rulebase-co/cx-alert-monitor-spec --- # Alert and monitor specs The pattern is always the same. Someone runs a search — every conversation where a customer threatened to go to the regulator, every ticket about a failing payment partner — finds it valuable, and asks to be told whenever it happens again. Almost every alert built this way is muted or ignored within two weeks, for one reason: **it fires more often than anyone budgeted for, and nobody measured that before shipping it.** The good news is that you already have the data to predict it. The historical sweep that motivated the alert *is* the volume forecast. ## Step 1: forecast the alert volume before building anything Run the detection rule over a historical window and count how often it would have fired, per day and per week. Then check that number against the reality of who is meant to act on it. Rough guidance, and worth stating to the user explicitly: | Firing rate | Viable if | | --- | --- | | A few per week | A named person reviews each one. This is the sweet spot. | | A few per day | There is a rota and a triage step. | | Tens per day | Only as a queue or a dashboard, never as a notification. | | Hundreds per day | Not an alert. It is a metric — chart it. | **If the forecast is above the budget, fix the rule or change the delivery. Do not ship it and hope.** An alert channel that people mute is worse than no alert, because everyone believes the risk is covered. State the forecast in the spec. It is the number that makes the alert's fate predictable rather than a surprise a fortnight later. ## Step 2: pick the precision target deliberately Precision and recall trade off, and the right point depends entirely on what happens when the alert fires. - **A human reviews each one and can dismiss it in seconds** — favour recall. A quarter of the alerts being irrelevant is tolerable if missing a real one is expensive. - **The alert triggers a costly action** — an escalation, waking someone, contacting a customer — favour precision hard. Every false positive spends credibility. - **Regulatory or safety topics** — favour recall, and route to a queue with an owner rather than an interrupt, so high volume does not force a precision compromise you cannot afford. Measure both on a labelled historical sample rather than guessing. Take the conversations the rule would fire on, label them by hand, and report the precision. A few dozen labelled examples is enough to tell a 90% rule from a 50% one, and that is the distinction that decides whether this ships. Write the measured precision into the spec, with the sample size. It is also the baseline for detecting decay later. ## Step 3: threshold detection or spike detection? These are different mechanisms and people conflate them. **Threshold** — "alert when any conversation matches X". Right for rare, individually important events: a regulator mention, a threat to close a major account, a specific compliance phrase. Volume scales with your traffic, so re-forecast when traffic grows. **Spike** — "alert when complaints about X rise unusually". Right for aggregate patterns where any single instance is unremarkable. Needs a baseline, and the baseline needs to respect the shape of support traffic: - **Seasonality is strong and multi-period.** Support volume has a day-of-week pattern and an intraday pattern, and both are large. A rule comparing this Monday to last Thursday will fire every week for no reason. - **Compare like to like** — same weekday, same hour band, over several weeks — or use a baseline that models the periodicity. - **Set the threshold on the historical distribution of the deviation**, not on a round number like "double". Report how often the rule would have fired historically and what was happening on those days. - **Beware of the denominator.** A spike in the *share* of contacts about X and a spike in the *count* mean different things; on a quiet day the share can jump on two extra tickets. Alert on both together, with a minimum count floor. - **A holiday calendar is not optional.** Public holidays break every baseline, and they differ per market. ## Step 4: state, dedup and escalation The mechanics that separate a monitor from a firehose: - **State.** The monitor must remember what it has already fired on. Alerting on the same conversation every run because it is still open is the fastest way to get muted. Persist fired ids. - **Dedup and group.** Twelve conversations about one outage is one incident. Group by the underlying cause where you can, and alert once with a count and a list. - **Cool-off.** After firing on a topic, suppress repeats for a defined window and report the accumulated count when it lifts. - **A named owner, not a channel.** An alert posted to a channel with no owner is read by nobody. Route to a person or a rota, and say what they are expected to do when it fires. If nobody will own it, that is a reason not to build it. - **What "acted on" means.** Define the closing action, so the alert can be measured later on whether it led to anything. - **A kill switch, and who may use it.** Every monitor needs to be turnable off by the people it wakes, without a deployment. ## Step 5: schedule its own review Monitors rot. The phrasing customers use changes, the product changes, the partner gets fixed, and the rule quietly stops matching or starts matching everything. Put a review date in the spec, and at review answer three questions: 1. **How often did it fire, versus the forecast?** 2. **What share of firings were acted on?** Near zero means retire it or fix precision — a monitor nobody acts on is a monitor nobody reads. 3. **Did it miss anything?** Look for incidents found another way that this should have caught. This is the only check on decaying recall, and it is the one always skipped. A monitor with no review date is a monitor that will be wrong indefinitely. ## Never automate these - **Replying to a customer.** Detection is not judgement. An alert may draft; a human sends. - **Closing, merging or reassigning** on the strength of a detection rule. - **Escalating to a regulator or a third party.** - **Anything irreversible**, on any confidence level. A monitor's job is to put the right conversation in front of the right person quickly. The moment it acts, its false-positive rate becomes a business risk rather than an annoyance. ## Spec template ```yaml name: regulator-mention-monitor owner: # not a channel purpose: detection: type: threshold # or spike rule: languages: [] scope: measured: window: would_have_fired: precision: % on hand-labelled examples known_misses: delivery: mode: notify | queue | dashboard dedup: cool_off: state: expected_action: kill_switch: review: next: retire_if: ``` ## Present results to the user 1. **The volume forecast**, first — how often this would have fired historically, per day and per week. This is the number that decides whether to build it. 2. **Measured precision and recall**, with the labelled sample size and examples of both false positives and misses. 3. **The spec**, as a file they keep. 4. **The delivery recommendation** — notify, queue, or chart — justified by the forecast rather than by the request. 5. **What it will miss**, stated plainly. Languages not covered, channels out of scope, phrasings the rule cannot catch. 6. **The review date**, and the condition under which it should be retired.
