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

Quick Rules
- Drop articles (a, the, an) — Claude doesn't need them
- Drop politeness (please, could you, I'd like) — zero effect on output
- Use aliases from CLAUDE.md — they're shared vocabulary
- Bullets > paragraphs — less ambiguous, fewer tokens
- Imply obvious steps — "add X to caddy" implies read/edit/save
