Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00090 | $0.02068 |
| Opus 5.5 | $0.00036 | $0.00827 |
| Sonnet 5.5 | $0.00018 | $0.00414 |
| Haiku 4.5 | $0.00009 | $0.00207 |
Grade C, and why
holmesgpt scanned grade C with 2 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 1mo 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

HolmesGPT Skill
AI-powered troubleshooting for Kubernetes and cloud-native environments.
Overview
HolmesGPT is a CNCF Sandbox project that connects AI models with live observability data to investigate infrastructure problems, find root causes, and suggest remediations. It operates with read-only access and respects RBAC permissions, making it safe for production environments.

Key Features
- Root Cause Analysis: Investigates alerts and cluster issues
- Multi-Source Integration: 30+ toolsets (K8s, Prometheus, Grafana)
- Alert Integration: AlertManager, PagerDuty, OpsGenie, Jira, Slack
- Interactive Mode: Troubleshooting with
/run,/show,/clear - Custom Toolsets: Extend with proprietary tools via YAML configuration
- CI/CD Integration: Automated deployment failure investigation
Installation Quick Start
CLI (Homebrew)
brew tap robusta-dev/homebrew-holmesgpt
brew install holmesgpt
export ANTHROPIC_API_KEY="your-key" # or OPENAI_API_KEY
holmes ask "what pods are unhealthy?"
Kubernetes (Helm)
helm repo add robusta https://robusta-charts.storage.googleapis.com
helm repo update
helm install holmesgpt robusta/holmes -f values.yaml
Docker
docker run -it --net=host \
-e OPENAI_API_KEY="your-key" \
-v ~/.kube/config:/root/.kube/config \
us-central1-docker.pkg.dev/genuine-flight-317411/devel/holmes \
ask "what pods are crashing?"
Essential Commands
# Basic investigation
holmes ask "what pods are unhealthy and why?"
holmes ask "why is my deployment failing?"
# Interactive mode
holmes ask "investigate issue" --interactive
# Alert investigation
holmes investigate alertmanager --alertmanager-url http://localhost:9093
holmes investigate pagerduty --pagerduty-api-key <KEY> --update
# With file context
holmes ask "summarize the key points" -f ./logs.txt
# CI/CD integration
holmes ask "why did deployment fail?" --destination slack --slack-token <TOKEN>
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

holmesgpt is a skill published in the GitHub repository julianobarbosa/claude-code-skills (14 stars, last pushed 11d ago), licensed MIT. It adds 90 tokens to every session and 2,068 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it C with 2 findings (reaches for credential files, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
