Observe vs Investigate: Always-on Agent vs On-demand CLI
This technical explainer compares two modes of kprompt's investigation system: an always-on Observe (namespace) agent that continuously watches a Kubernetes namespace and raises gated incidents, and an on-demand investigate CLI used for reactive root-cause analysis from a laptop or CI. The article describes differences in trigger, scope, mutation model, artifacts (Incident / AgentAlert vs Investigation / PlanResult), RBAC (default namespace Role), and optional Autopilot behavior (propose-only PlanResult requiring approval). It includes command examples, links to the kprompt GitHub docs and blog, notes that heuristic Observe needs no LLM key while investigate can use an LLM provider for richer narration, and recommends trying workflows in non-production (kind) clusters first.
Developer-focused technical explanation of an observability/agent workflow (kprompt) that is relevant to APM and AI-assisted troubleshooting but is not a major platform policy or industry-wide change.

Key Takeaways & Evidence Grounding
- kprompt provides an on-demand CLI command set (investigate/why/timeline) for reactive root-cause analysis against kubeconfig contexts.
- kprompt offers an always-on Observe namespace agent that continuously watches a single namespace and emits Incidents/AgentAlerts without default mutation.
- Autopilot (opt-in) can propose PlanResult mutation suggestions after an Incident, but applies changes only after gated approval (PlanResult Applied=false by default).
- Default RBAC for the Observe agent is a namespace Role with get/list/watch permissions, not a ClusterRole.
- Heuristic Observe mode requires no LLM key; the investigate CLI can use an LLM provider for richer narrative output.

Demo kprompt Observe agent on broken kind cluster
This technical walkthrough demonstrates kprompt v0.5's optional Observe agent by intentionally breaking a local 'kind' Kubernetes cluster using the kprompt-examples fixture set. The Observe agent can run in an offline heuristic mode (no LLM/API key) to continuously watch a namespace, correlate incidents from live Events/Pods, and gate notifications to Slack/webhooks. The demo covers seven failure scenarios (CrashLoop, ImagePull, OOM, stalled rollout, unbound PVC, failing CronJob, missing Redis hostname), shows the agent producing correlated incidents rather than noisy per-event alerts, and reiterates that Autopilot is propose-only—Observe will not apply changes by default. The post links to kprompt docs and GitHub repos for code, ADRs, and operational guidance.
Stop paging on every kubelet event with incidents and gates
Muhtalip Dede explains why piping every Kubernetes kubelet Event into Slack causes alert fatigue and why observability should correlate raw Events into durable Incidents gated by severity and confidence. The post describes kprompt's Observe agent, which watches Pods/Events in a namespace, correlates evidence into Incidents, can optionally analyze evidence with a BYOK LLM, and only notifies Slack/Discord/webhooks after configurable severity + confidence gates. It outlines levers to reduce noise (heuristic mode, min-severity/min-confidence, incident batching, memory/patterns, Slack threading) and reiterates that autopilot remains propose-only (no silent remediation). The post links to kprompt examples and architecture docs for further details.
Observability for Agentic Systems: Dashboards Mislead
The article explains why traditional request-response observability tools and dashboards fail to capture the behavior of agentic LLM systems. Agent traces are directed graphs with loops, retries, branching and sub-agents, not simple trees; agents commonly make 6–27 tool calls per investigation. Emerging practices include OpenTelemetry's gen_ai.* semantic conventions (stabilized in early 2026), Red Hat's W3C context propagation across MCP boundaries, and Discord's Envelope pattern with fanout-aware sampling. Three storage and analytics challenges—retention, sampling, and rollups—are especially damaging to agent debugging; ClickHouse proposes 30–365 day full-fidelity retention at ~$0.0005/GB/month. Practical guidance: enable gen_ai.* attributes, extend retention (recommend ~90 days), use hybrid auto+manual instrumentation (roughly 60% auto, 25% semi-auto, 15% manual), and adopt tail/agent-aware sampling and token-cost observability.
