coroot

coroot is a skill for Claude Code, Codex from Arvo-AI/aurora. It costs 35 tokens per session (1,607 once invoked), scanned A, original, Apache-2.0.

A connection to Coroot, a monitoring platform that observes servers, containers, networks, and services without requiring application code changes. It uses eBPF, a Linux feature that collects system activity from the operating system.

In plain words
What is it for?
Use it to investigate incidents through service maps, traces, logs, deployments, infrastructure data, costs, and risk information. It can also show activity from databases and other common network services.
Why use it?
It helps reveal problems that application logs may miss, such as failed connections, slow networks, disk delays, resource limits, and service dependencies.

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

coroot 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 5d 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.

Coroot Integration

Overview

Coroot is an eBPF-powered observability platform. Its node agent instruments at the KERNEL level, capturing data that applications cannot self-report and requires NO code changes or SDK integration.

What eBPF Gives You (data invisible to application logs)

  • TCP connections: every connect/accept/close between services, including failed connects and retransmissions
  • Network latency: actual round-trip time measured at the kernel, not application-reported
  • DNS queries: every resolution with latency, NXDOMAIN errors, and server failures
  • Disk I/O: per-process read/write latency and throughput at the block device level
  • Container resources: CPU usage, memory RSS, OOM kills, throttling -- from cgroups
  • L7 protocol parsing: HTTP, PostgreSQL, MySQL, Redis, MongoDB, Memcached request/response metrics extracted from TCP streams without application instrumentation
  • Service map: automatically discovered from observed TCP connections -- not configured manually

Issues Coroot Sees BEFORE Application Logs

  • A service failing to connect to a dependency (TCP connect failures)
  • Network packet loss and retransmissions between pods/nodes
  • DNS resolution failures causing timeouts
  • Disk I/O saturation causing slow queries
  • OOM kills that happen before the app can log anything
  • Container CPU throttling invisible to the application

Instructions

Incident Investigation Flow

  1. coroot_get_incidents(lookback_hours=24) -- List incidents with RCA summaries, root cause, and fixes
  2. coroot_get_overview_logs(severity='Error', limit=50) -- Search all logs cluster-wide for errors (includes Kubernetes Events: OOMKilled, Evicted, CrashLoopBackOff, FailedScheduling)
  3. coroot_get_incident_detail(incident_key='KEY') -- Full incident detail with propagation map
  4. coroot_get_app_detail(app_id='ID') -- Audit reports for affected app (35+ health checks)
  5. coroot_get_app_logs(app_id='ID', severity='Error') -- Error logs with trace correlation
  6. coroot_get_traces(service_name='svc', status_error=True) -- Error traces across services
  7. coroot_get_traces(trace_id='ID') -- Full trace tree for a specific request

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.

coroot is a skill published in the GitHub repository Arvo-AI/aurora (404 stars, last pushed today), licensed Apache-2.0. It adds 35 tokens to every session and 1,607 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
