alert-mute-copilot
One-stop assistant for creating, editing, and troubleshooting Nightingale (n9e) alert mute rules (alert_mute). Use it when the user asks to "create a mute rule / mute an alert / silence an alert / do-not-disturb during a maintenance window / set up periodic muting / mute every early morning / adjust or extend a mute / troubleshoot why a mute isn't working". Muting takes effect during the event evaluation stage (muted events are neither persisted nor notified); to configure "which events get notified to whom", use notification rules (→ notify-rule-copilot); to investigate "why didn't I get a notification", go to alert troubleshooting (→ alert-
aiagent/skill/embedded/builtin/alert-mute-copilot/SKILL.md · Apache-2.0 · 2026-11-03License source ↗alert-rule-troubleshoot
This skill should be used when the user reports that an alert rule is "not firing", "no alert was sent", "the rule didn't trigger", "the rule isn't working", "it should have alerted but didn't", "why didn't I get an alert", "alert rule not firing", or wants to diagnose why a specific alert rule failed to produce an event/notification. Use this skill to troubleshoot "why an alert rule did not fire as expected", as opposed to taking an existing alert and finding its root cause (for the latter, use ops-troubleshooting). Only supported on Release 22 and above.
aiagent/skill/embedded/builtin/alert-rule-troubleshoot/SKILL.md · Apache-2.0 · 2026-11-03License source ↗alert-subscribe-copilot
One-stop assistant for creating, editing, and troubleshooting Nightingale (n9e) alert subscription rules (alert_subscribe). Use when the user asks to "create a subscription rule / subscribe to alerts / forward alert events / CC another team / escalate alerts (notify someone else after N minutes unhandled) / receive alerts across business groups / troubleshoot a subscription not taking effect". A subscription is a "copy + secondary routing" of events at the notification stage; to configure "who an event directly notifies" use notification rules (→ notify-rule-copilot), and to stop receiving alerts use muting (→ alert-mute-copilot).
aiagent/skill/embedded/builtin/alert-subscribe-copilot/SKILL.md · Apache-2.0 · 2026-11-03License source ↗analyze-dashboard
Analyze the data health of a given dashboard on Nightingale (n9e) over a time window. Use when the user asks to "analyze what problems a dashboard has", "check whether the xx dashboard has been normal over the last 24 hours", "inspect this dashboard", or "does this dashboard have any anomalies". Distinct from modifying a dashboard (modify-dashboard) and creating a dashboard (create-dashboard).
aiagent/skill/embedded/builtin/analyze-dashboard/SKILL.md · Apache-2.0 · 2026-11-03License source ↗categraf-deploy-guide
Answers "how do I deploy the categraf collector". Trigger scenarios: the user asks "how to install categraf / how to deploy categraf / run categraf with Docker / install categraf on Windows / how to register categraf as a system service / report categraf to Nightingale / how to write categraf config.toml / how to verify that categraf is collecting data". Covers binary + systemd, Docker, Windows, K8s tips, key configuration, and common verification commands. This skill is instructional/guidance-oriented, calls no tools, and outputs ready-to-paste commands and configuration snippets.
aiagent/skill/embedded/builtin/categraf-deploy-guide/SKILL.md · Apache-2.0 · 2026-11-03License source ↗create-alert-rule
**Create alert rules**. Prefer reusing the validated rules in integrations (standard components like Linux/MySQL/Redis/Kafka/PostgreSQL/Elasticsearch all ship ready-made rule packs); import as many rules as the user needs—one rule, a batch, or a whole pack. Only hand-write a custom rule when integrations has nothing that fits. Supports all data sources: Prometheus / Loki / ES / OpenSearch / MySQL / PG / TDengine / ClickHouse / Doris / VictoriaLogs / Host. ⚠️ **
aiagent/skill/embedded/builtin/create-alert-rule/SKILL.md · Apache-2.0 · 2026-11-03License source ↗create-dashboard
Create monitoring dashboards. Use this when the user asks to create a dashboard, a monitoring board, or a Dashboard.
aiagent/skill/embedded/builtin/create-dashboard/SKILL.md · Apache-2.0 · 2026-11-03License source ↗doc-qa
This skill should be used when the user asks "how-to" or factual questions about Nightingale (n9e) — UI/where-to-click, business groups/subscription rules/mute rules/edge mode, Token usage, notification pipeline, self-healing trigger conditions; OR about categraf input plugin field meanings, metric names, defaults, environment variables, config syntax (e.g. "how to write [[instances]]", "unit of ping_average_response_ms"); OR about the n9e / categraf / fe source code — this skill carries an embedded, searchable snapshot of the three repositories, so use it whenever the user asks "can you read the source code / the code directory", or asks how
aiagent/skill/embedded/builtin/doc-qa/SKILL.md · Apache-2.0 · 2026-11-03License source ↗explorer-query
Use when the user wants to generate, repair, validate, or prepare a query for the current Nightingale Metrics Explorer or Log Explorer panel. Supports PromQL for Prometheus-compatible datasources, SQL for MySQL and Doris, and Doris log queries. Verify the statement against the selected datasource before returning it. Use query-datasource when the user only wants to view data rather than prepare a statement for an editor.
aiagent/skill/embedded/builtin/explorer-query/SKILL.md · Apache-2.0 · 2026-11-03License source ↗generate-message-template
Generate or modify Nightingale (n9e) alert notification message templates. Use when the user asks to write a notification template, change the message format, add hostname/recovery value/severity, or create DingTalk/Feishu/Lark/email/SMS/voice templates.
aiagent/skill/embedded/builtin/generate-message-template/SKILL.md · Apache-2.0 · 2026-11-03License source ↗host-health-diagnose
Help the user determine whether a machine is truly down / the agent is hung / the network is flapping / it is under maintenance. Triggers this skill when the user asks "why is this machine unreachable", "is the host-unreachable alert a false positive", "is categraf stuck", "the heartbeat stopped but I can still ping it", etc. Core stance: **an unreachable agent != a down host**. Concluding "down" just because target_up==0 / BeatTime stopped is a common source of false positives.
aiagent/skill/embedded/builtin/host-health-diagnose/SKILL.md · Apache-2.0 · 2026-11-03License source ↗host-onboard-diagnose
Diagnose onboarding failures where "categraf is installed/running but the host does not show up in the Nightingale host list, or shows unknown / has no metrics". Triggers when the user asks "why doesn't my newly installed host appear", "all the OS values in the host list are unknown", "I installed 3 collectors via Helm but only see 1", "the agent won't register", or "categraf is installed but the host doesn't show". **Mutually exclusive** with host-health-diagnose: that one handles "was onboarded before, now lost contact", while this skill handles "never got onboarded at all". Core stance: **a missing host is not a single cause, but rather on

**Bulk import of a Prometheus alert rule YAML file** (create a whole set of rules at once). Dedicated to handling a remote URL or local YAML text, automatically parsing the three formats `groups` / a plain `rules` array / a single rule. ⚠️ **
aiagent/skill/embedded/builtin/import-prom-rule/SKILL.md · Apache-2.0 · 2026-11-03License source ↗modify-dashboard
Modify an existing monitoring dashboard on Nightingale (n9e). Use when the user asks to change a dashboard's variables, check and fix variables, modify charts/series (change PromQL, legend, unit, add/remove series), rename a chart, or change the chart type (e.g., turn a stat chart into a timeseries chart). Distinct from "creating a dashboard from scratch" (that is create-dashboard).
aiagent/skill/embedded/builtin/modify-dashboard/SKILL.md · Apache-2.0 · 2026-11-03License source ↗modify-task-tpl
Helps users generate, modify, or troubleshoot Nightingale (n9e) alert self-healing scripts (task_tpl / ibex scripts). Use when the user asks to "write a self-healing script for disk cleanup / restarting a service / cleaning logs / dumping a process / reloading nginx", or asks "how does a self-healing script get the parameters passed from the alert", "what format is stdin in", "what should I set timeout to", "why is is_recovered always false", "why can't my self-healing script get the k8s namespace", "what do I do when a script stays running forever". This skill focuses on the **script body layer**—if the user wants to change alert rules, reci
aiagent/skill/embedded/builtin/modify-task-tpl/SKILL.md · Apache-2.0 · 2026-11-03License source ↗notify-channel-copilot
Helps users modify, create, or troubleshoot Nightingale (n9e) notify channels (notify_channel). Use it when the user asks to change the URL, request body, signature, headers, proxy, TLS, @-mentions, or recipient fields of channels such as DingTalk/Feishu/WeCom/email/SMS/voice/Webhook, or asks "how do I integrate platform X" or "why can't it send / why am I getting 9499 / Bad Request". This skill focuses on **the channel-layer configuration**—if the user is changing "message content/fields/rendering", switch to generate-message-template instead.
aiagent/skill/embedded/builtin/notify-channel-copilot/SKILL.md · Apache-2.0 · 2026-11-03License source ↗notify-rule-copilot
One-stop assistant for creating, editing, copying, and troubleshooting Nightingale (n9e) notify rules (notify_rule). Use it when the user asks to "create a notify rule / add a notification policy / configure how alerts are delivered / edit and adjust a notify rule / tiered notification / route by business group or label / take different actions during vs. outside working hours / don't call on recovery / fix a rule that isn't matching" — it is especially good at decomposing natural-language routing requirements into a correct NotifyConfig array. This skill focuses on the routing layer of notify rules: it does not touch the notification media t
aiagent/skill/embedded/builtin/notify-rule-copilot/SKILL.md · Apache-2.0 · 2026-11-03License source ↗ops-troubleshooting
