alert

alert is a skill for Claude Code from Rootly-AI-Labs/rootly-claude-plugin. It costs 53 tokens per session (885 once invoked), scanned A, original, Apache-2.0.

A Rootly alert investigation workflow. An alert is an incoming warning that may or may not become a tracked incident.

In plain words
What is it for?
Use it when a page arrives and you need context to ignore, acknowledge, escalate, or open an incident.
Why use it?
It gathers the alert's history, related alerts, and connected incident so you can judge what happened before deciding what to do.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Alert Triage

You are helping the user triage a Rootly alert. Alerts are the upstream signal that may or may not become incidents. The goal is to give the user enough context in one place that they can decide: ignore, acknowledge, escalate, or open an incident.

Workflow

1. Resolve the alert

$ARGUMENTS should contain a short alert ID (e.g. A-1234 or 1234).

  • If $ARGUMENTS is empty: report "No alert ID provided. Pass a short ID like A-1234 or 1234." and stop.
  • Otherwise call mcp__rootly__get_alert_by_short_id with the value as given.
  • If that fails, fall back to mcp__rootly__getAlert with the same value (the MCP layer often accepts both forms).
  • If both fail, surface the error and stop.

2. Gather context

Once you have the alert UUID:

  1. Call mcp__rootly__listAlertEvents (or filter by alert) to get the event timeline.
  2. If the alert response includes an alert_group_id or group reference, call mcp__rootly__getAlertGroup for sibling alerts.
  3. If the alert is attached to an incident, the response usually carries an incident_id. Call mcp__rootly__getIncident for incident context.
  4. Optional: call mcp__rootly__listAlerts filtered to the same source/service in the last 24h to surface "is this alert flapping?"

Stop fetching once you have enough to render the brief — do not keep walking endpoints.

3. Present the alert brief

## Alert Brief: [alert title]

**Short ID**: [short-id] | **Source**: [source] | **Urgency**: [urgency]
**Started**: [time] ([duration] ago) | **State**: [state]
**Service**: [service or "unmapped"]

### Summary
[Alert summary or first event message]

### Event Timeline
- [time] [event-type]: [message]
- [time] [event-type]: [message]
[at most 8 events, oldest first]

### Group Context
[If part of a group:]
This alert is one of [N] in group [group-name]. Other open alerts in the group:
- [short-id] [title] ([state])

[If flapping detected:]
**Flapping**: this source has fired [N] alerts in the last 24h on the same service.

### Incident Linkage
[If attached to an incident:]
Already attached to **[INC-XXXX]** [title] ([severity], [status]).

[If not attached:]
Not attached to an incident.

### Suggested Next Step
[Pick one based on the data:]
- "Acknowledge — looks like a known transient pattern"
- "Open an incident — first occurrence, customer-facing surface"
- "Escalate — already linked to a critical incident with no responder yet"
- "Ignore — historical noise from this source on this service"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
