+# Claude Shorthand Cheat-Sheet
+
+## Core Operators
+
+| Pattern | Meaning | Example |
+|---------|---------|---------|
+| `→` | then (sequential) | `ssh pve173 → zpool status` |
+| `+` | and (parallel) | `check caddy + check pihole` |
+| `X ? Y : Z` | if X then Y else Z | `port open ? connect : debug` |
+| `!X` | don't / skip | `!error handling` |
+| `w/` | with | `py script w/ argparse` |
+| `@` | at path/location | `new config @ /etc/caddy/` |
+| `re:` | regarding | `fix re: tank degraded drive` |
+| `=` | set/assign | `port=3000, lang=python` |
+| `~` | approximately / like | `~50 lines, ~yesterday` |
+| `>>` | output to / save to | `results >> /tmp/report.txt` |
+| `<-` | from / source | `data <- freshrss API` |
+
+## Spec Block (complex tasks)
+
+```
+feat: <short description>
+- lang: <language>
+- deps: <dependencies>
+- in: <input/source>
+- out: <output/target>
+- !: <things to skip>
+```
+
+## Examples
+
+### Verbose → Compressed
+
+**Service setup:**
+```
+# Before (~80 tokens):
+"Please create a new Python service in the printer-automation directory
+that connects to the FreshRSS API, fetches today's articles, formats
+them for the receipt printer, and runs as a systemd service"
+
+# After (~20 tokens):
+feat: daily print @ printer-automation/
+- freshrss API → format → receipt printer
+- systemd service
+```
+
+**Infra task:**
+```
+# Before (~50 tokens):
+"SSH into pve173, check if any drives in the tank pool are degraded,
+and if so tell me which ones need replacement"
+
+# After (~12 tokens):
+pve173 → tank degraded drives? → list replacements
+```
+
+**Multi-step:**
+```
+# Before (~60 tokens):
+"First read the Caddyfile, then add a new reverse proxy entry for
+wiki.sethpc.xyz pointing to 192.168.0.160 port 3000, and also
+add it to the Pi-hole DNS"
+
+# After (~15 tokens):
+add wiki.sethpc.xyz → .160:3000 to caddy + pihole
+```
+
+**Conditional:**
+```
+# Before (~45 tokens):
+"Check if ollama is running on pve197. If it is, test the qwen model.
+If it's not running, start it first then test."
+
+# After (~15 tokens):
+pve197: ollama running ? test qwen : start → test
+```
+
+## Anchors (use known names)
+
+| Say | Not |
+|-----|-----|
+| `pve173` | "the PowerEdge node at 192.168.0.173" |
+| `tank` | "the ZFS pool on node-173" |
+| `caddy` | "the reverse proxy in CT 600" |
+| `pihole` | "the DNS server at 192.168.0.153" |
+| `steel141` | "this machine, my gaming PC" |
+| `ollama` | "the LLM inference service" |
+
+## Quick Rules
+
+1. Drop articles (a, the, an) — Claude doesn't need them
+2. Drop politeness (please, could you, I'd like) — zero effect on output
+3. Use aliases from CLAUDE.md — they're shared vocabulary
+4. Bullets > paragraphs — less ambiguous, fewer tokens
+5. Imply obvious steps — "add X to caddy" implies read/edit/save
