+
+When I use a coding agent (Cursor Agent, Claude Code CLI, Ampcode, etc.), I repeat the same requests: "review this function," "explain this error," "add tests for this module," "format this as a blog post." Typing long prompts from scratch is tedious; ad-hoc prompts are easy to forget. I also keep pasting the same background (API conventions, project rules, infra notes) into every session so the agent doesn't guess blindly.
+
+### Approach
+
+Treat prompts and context as first-class artefacts: store them as markdown files (one per slash-command or per context) in a dotfiles repo. Use a small set of *meta* slash-commands so the agent itself creates, updates, and deletes these files from the conversation—no hand-editing. Two kinds of artefacts:
+
+* Commands — Reusable workflows (e.g. review-code, explain-error). Live in `commands/` as `.md` files.
+* Context — Reusable background (API guidelines, runbooks, personas). Live in `context/` as `.md` files; you *load* one at session start so the agent has it in mind.
+
+### Copy/paste
+
+Minimal workflow:
+
+```
+/load-context api-guidelines
+```
+
+Then ask the agent to implement a feature or fix a bug; it already has the guidelines.
+
+To turn something you just did into a reusable command:
+
+```
+/create-command review-code
+```
+
+Full command reference (all meta-commands, parameters, examples):
+
+[Meta slash-commands — full reference](./2026-02-14-meta-slash-commands-for-prompts-and-context.md)  
+
+### Result
+
+No more retyping long prompts; same prompt library across Cursor Agent, Claude Code CLI, OpenCode, Ampcode. Context is load-on-demand per session instead of pasting walls of text. Everything is versioned in git and synced across machines.
+
+### Gotchas
+
+* Requires an agent that supports custom slash-commands (or reading prompt files from disk).
+* Context is explicit: you must run `/load-context <name>` at session start; it's not implicit like some "skills" systems.
+* A flat directory of commands can grow; if it gets unwieldy, consider grouping by skill or exposing via an MCP server later.
+
+## Before/After
+
+* Before: Retyping or pasting long prompts each time; pasting API/project context into every session; prompts scattered and inconsistent across tools.
+* After: `/load-context <name>` once per session; `/<command>` for repeatable tasks; commands and context in git, same library across agents.
+
+## Workflow recipe
+
+* Steps: (1) Create or update context/commands via meta-commands when you have something worth reusing. (2) Start a session → run `/load-context <name>`. (3) Use slash-commands or ask ad-hoc; agent has background and consistent prompts.
+* Tools: Cursor Agent (CLI), Claude Code CLI, OpenCode, Ampcode; markdown in e.g. `~/Notes/Prompts/commands/` and `~/Notes/Prompts/context/`.
+* Impact: Saves retyping and keeps prompts consistent; one-time cost is creating the first context/command with the agent.
+
+## Micro-template (quick reference)
+
+| Meta-command       | Purpose                        | Good for                                  |
+|--------------------|--------------------------------|-------------------------------------------|
+| /create-command    | Create new slash-command       | Turn current or recurring tasks into one  |
+| /update-command    | Edit existing slash-command    | Refine after use                          |
+| /delete-command    | Remove slash-command file      | Clean up unused commands                  |
+| /create-context    | Create new context file        | Capture project/infra knowledge once      |
+| /update-context    | Edit existing context file     | Keep context up to date                   |
+| /delete-context    | Remove context file            | Remove outdated context                   |
+| /load-context      | Load context into conversation | Give agent background before tasks        |
+
+Example usage: `/load-context api-guidelines`, `/create-command review-code`, `/update-command review-code`. Full details and examples in the main post linked above.

+# Loadbars resurrected: From Perl to Go after 15 years
+
+> Published at 2026-02-14T22:43:27+02:00
+
+Who remembers Loadbars? The small, humble server load monitoring tool I wrote back in November 2010 as a Perl+SDL project during my first job after graduating from university as a Linux Sysadmin. That was over 15 years ago. After being effectively dead for more than a decade, Loadbars is working again -- rewritten in Go from Perl with the help of AI (Claude Code), and it even works on macOS now (as a client).

+## What Loadbars is (and isn't)
+
+Loadbars is a real-time server load monitoring tool. It connects to one or more Linux hosts via SSH and shows CPU, memory, and network usage as vertical colored bars in an SDL window. You can also run it locally without SSH. It shows the current state only -- like `top` or `vmstat`, but visual and across multiple hosts at once. All you need is a working SSH connection through an SSH Agent.
+
+It is not a tool for collecting loads and drawing graphs for later analysis. There is no history, no recording, no database. Tools like Prometheus or Grafana require significant setup time before producing results. Loadbars lets you observe the current state immediately. You install one binary, point it at your servers, and see what's happening right now.

+
+## Why the rewrite was necessary
+
+I'd have liked to have kept the Perl version. Perl was the first language I learned properly, and I have a soft spot for it. But there was an (for me) unresolvable multithreading issue related to recent Perl and SDL library versions. Perl's `ithreads` and SDL doesn't work reliably anymore, and debugging decade-old thread-safety issues in XS bindings is not a productive use of time.
+
+I actually tried to fix the Perl version first. I had Claude Code (CLI, running Opus 5.3) attempt to resolve the segfault involving Perl's multi-threading and SDL. It couldn't—the issue is deep in the XS bindings and not something you can fix from Perl-land (nor did I want to invest my own time in it either). So the more pragmatic thing to do was to let Claude Code rewrite the whole thing in Go instead. That worked without any major issues. The Go version is cleaner, faster to build, easier to deploy (single static binary), and now has proper unit tests.
+
+The important thing: for the user, nothing changes. The rewrite's usage, look, and feel are de-facto identical to the old Perl version. The same hotkeys, the same bar layout, the same colors, the same config file format. If you used Loadbars ten years ago, you can pick up the new version and everything works exactly as you remember. The only difference is under the hood.
+
+## A brief history
+
+The first commit is from November 5, 2010—over 13 years ago. Back then, it was called `cpuload` and was a quick Perl+SDL hack I wrote at work to keep an eye on a fleet of Linux servers. It grew into Loadbars over the following weeks, gaining memory and network monitoring, ClusterSSH integration, and a config file. The last meaningful Perl development was around 2013. Around that time, there were already a couple of colleagues who used Loadbars frequently. But then I changed my job role and later even jobs, and I stopped development of Loadbars.
+
+For the next decade, it sat dormant. I occasionally thought about reviving it, but Perl+SDL threading issues made it impractical. In February 2026, I finally sat down with Claude Code and let it rewrite the whole thing in Go in a single session.
+
+## Features
+
+### CPU monitoring
+
+CPU usage is shown as vertical colored bars. Each bar is stacked from bottom to top with the following segments:
+
+* System (blue) -- kernel CPU time
+* User (yellow) -- user-space CPU time; turns dark yellow above 50%, orange above 70%
+* Nice (green) -- low-priority user processes
+* Idle (black) -- unused CPU
+* IOwait (purple) -- waiting for disk I/O
+* IRQ / SoftIRQ (white) -- interrupt handling
+* Guest (red) -- time spent running virtual CPUs
+* Steal (red) -- time stolen by the hypervisor
+
+Press `1` to toggle between one aggregate bar per host and one bar per core. Press `e` for extended mode, which adds a 1px peak line showing the maximum system+user percentage over the last N samples.
+
+### Memory monitoring
+
+Press `2` to toggle memory bars. Each host gets one bar split in two halves:
+
+* Left half: RAM usage (dark grey = used, black = free)
+* Right half: Swap usage (grey = used, black = free)
+
+### Network monitoring
+
+Press `3` to toggle network bars. Loadbars sums RX and TX bytes across all non-loopback interfaces (e.g. `eth0`, `wlan0`, `enp0s3`) and shows the combined total. Loopback (`lo`) is always excluded. Each net bar has two halves:
+
+* Left half: RX (received) growing from the top (light green)
+* Right half: TX (transmitted) growing from the bottom (light green)
+
+Network utilization is shown as a percentage of the configured link speed. The default link speed is `gbit` (1 Gbps). Change it with `--netlink` or in the config file. Press `f`/`v` to scale the link speed up or down during runtime (cycles through mbit, 10mbit, 100mbit, gbit, 10gbit).
+
+If the net bar is red, it means no non-loopback interface was found on that host.
+
+### All hotkeys
+
+```
+Key     Action
+─────   ──────────────────────────────────────────────────
+1       Toggle CPU cores (aggregate vs per-core bars)
+2       Toggle memory bars
+3       Toggle network bars (aggregated across interfaces)
+e       Toggle extended display (peak line on CPU bars)
+h       Print hotkey list to stdout
+q       Quit
+w       Write current settings to ~/.loadbarsrc
+a / y   Increase / decrease CPU average samples
+d / c   Increase / decrease net average samples
+f / v   Link scale up / down (net utilization reference)
+Arrows  Resize window (left/right: width, up/down: height)
+```
+
+### SSH and multi-host support
+
+Loadbars connects to remote hosts via SSH using public key authentication. No agent or special setup is needed on the remote side -- Loadbars embeds a small bash script in the binary and runs it via `bash -s` over SSH. The remote hosts only need bash and `/proc` (i.e. Linux).
+
+```
+loadbars --hosts server1,server2,server3
+
+loadbars --hosts root@server1,root@server2
+
+loadbars servername{01..50}.example.com --showcores 1
+```
+
+Shell brace expansion works for specifying ranges of hosts. You can also use ClusterSSH cluster definitions from `/etc/clusters`:
+
+```
+loadbars --cluster production
+```
+
+When no hosts are given, Loadbars runs locally on `localhost` without SSH.
+
+### Config file
+
+Loadbars reads `~/.loadbarsrc` on startup. Any option from `--help` can be set there without the leading `--`. Comments use `#`. Press `w` during runtime to write the current settings to the config file.
+
+```
+showcores=1
+showmem=1
+shownet=1
+extended=1
+netlink=gbit
+cpuaverage=10
+netaverage=15
+height=150
+barwidth=1200
+```
+
+### macOS support
+
+macOS is supported as a client for monitoring remote Linux servers via SSH. Local monitoring on macOS is not supported because it requires the `/proc` filesystem. The SDL window is automatically brought to the foreground on macOS.
+
+## Building from source
+
+Loadbars requires Go 1.25+ and SDL2. Install the SDL2 development libraries for your platform:
+
+```
+# Fedora / RHEL / CentOS
+sudo dnf install SDL2-devel
+
+# macOS
+brew install sdl2
+```
+
+Then build with Mage (recommended) or plain Go:
+
+```
+mage build
+./loadbars --hosts localhost
+
+# or without Mage:
+go build -o loadbars ./cmd/loadbars
+```
+
+Install to `~/go/bin`:
+
+```
+mage install
+```
+
+Run tests:
+
+```
+mage test
+# or: go test ./...
+```
+
+## Tested platforms
+
+* Fedora Linux 43 and most modern Linux distributions (RHEL, CentOS, Ubuntu, Debian, etc.)
+* macOS (Darwin) as a client connecting to remote Linux servers via SSH
+
+Remote hosts must be Linux with `/proc` and bash.
+
+## Future-proof with Go
+
+One of the reasons I chose Go for the rewrite is Go's compatibility promise. The Go 1 compatibility guarantee means that code written today will continue to compile and work with future Go releases. No more bitrotted XS bindings, no more `ithreads` headaches, no more hunting for compatible versions of SDL Perl modules.
+
+The Go SDL2 bindings (go-sdl2) are actively maintained, and SDL2 itself is a stable, well-supported library. The entire application compiles to a single static binary with no runtime dependencies beyond SDL2. Deploy it anywhere, run it for years.
+
+## The AI rewrite experience
+
+This resurrection would not have been really possible without the help of AI. The rewrite was done with Claude Code CLI (Anthropic's coding agent) running Claude Opus 5.3. I pointed it at the Perl source,  and let it produce the Go equivalent. The process was surprisingly smooth -- the rewrite worked without any major issues. There were some minor bugs (such as network bars not showing up initially, and/or some pixel errors in the bars), but they were sorted by Claude by providing screenshots of the problems.
