investigate

investigate is a skill for Claude Code from aws-samples/sample-aws-devops-agent-claude-plugin. It costs 88 tokens per session (1,662 once invoked), scanned A, original, MIT-0.

A guided workflow for finding the underlying cause of AWS incidents, such as outages, alarms, failed deployments, high error rates, or unusual delays.

In plain words
What is it for?
Investigating errors such as 5xx responses, 503s, out-of-memory failures, latency spikes, rollbacks, and service outages.
Why use it?
It helps turn a reported symptom into a structured root-cause investigation instead of leaving the developer to search through unrelated clues.

About the project

aws-samples/sample-aws-devops-agent-claude-plugin is a Claude Code plugin that connects the coding agent to AWS DevOps Agent through the AWS MCP Server, allowing it to use AWS operational information alongside local workspace context. It is intended for investigating incidents, discussing AWS costs and architecture, and working with AgentSpaces. Its skills, commands, and MCP tools provide the plugin workflow for these operations.

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

investigate 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 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.

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.

Changes

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.
