How I use Claude Code to manage sysadmin tasks
2 months ago
- Use individual folders with CLAUDE.md files for task sets, versioned separately in Git, to manage sysadmin tasks with Claude Code.
- Structure folders by project and task group (e.g., app maintenance, DBA) including server info, project context, and common tasks for progressive disclosure.
- Enhance security by using SSH keys, bastion hosts, and ~/.ssh/config aliases to avoid storing credentials in repos.
- Pair rigorously with Claude Code: research each step, ask for plans and verification, and review every SSH command before execution.
- Document processes in CLAUDE.md after tasks (e.g., backups) to create self-documenting playbooks with verification steps and known issues.
- Extend the approach to cloud-first environments using CLI tools (e.g., gcloud, aws) with proper access management.
- Separate sysadmin CLAUDE.md from code repos to avoid context confusion and allow overarching infrastructure views.
- Update CLAUDE.md regularly to accumulate resolved issues and reflections, improving future resolution time and documentation.
- Make CLAUDE.md human-readable—summarize or convert to HTML for team sharing and cross-server queries.
"As Code"

- Mitchell Hashimoto defines 'X as Code' as a system of principles or rules, not as programming.
- His intent was to inscribe knowledge from people's minds into a shareable, versioned, and iterable system.
- Codified knowledge is computer-readable, enabling automation and validation, but doesn't require all modern programming practices.
- This mindset is reflected in the 'codification' sections of the Tao of HashiCorp, written over a decade ago.
- He clarifies that this post is not a criticism of 'as programming' ideals or a claim that 'as code' is perfect.
We compiled our TypeScript parser to WASM

- Encore determines application infrastructure by reading TypeScript code and provisions corresponding resources like APIs, databases, and Pub/Sub topics.
- The parser, written in Rust and compiled to WASM, now runs in browsers, enabling bug reproduction via code snippets and shared links without needing local projects.
- To function in browsers, filesystem dependencies were removed via Cargo features, and in-memory resolution replaces disk operations, with SDK files baked into the WASM binary.
- A playground at tsparser.encore.dev allows testing and sharing parser outputs, ensuring consistency across CLI, CI, and browser environments.
