Condense a message to five sentences or fewer with the High-Five Habit, for email, Slack, text and social posts. Use when asked to condense, shorten, tighten or make a message shorter, reduce message length, write a brief or concise message, or draft an email template.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Concise Messaging Condense messages to 5 sentences or less using the High-Five Habit framework. Most messages can and should be this concise. ## Binding rules 1. **Five sentences or fewer** for most messages. The limit forces clarity and respects the reader's time. 2. **When condensing loses critical nuance, suggest a call or meeting** instead of forcing it; in Slack, a third message means a huddle. 3. **Lead with the purpose and end with a clear next step.** Skip openers like "I hope this finds you well." 4. **Cut what does not earn its place:** filler, hedging, redundant context, buzzwords and needless apologies. 5. **Keep the writer's voice.** Apply voice preferences from `CLAUDE.md` or `AGENTS.md` when present, match the recipient's tone, and be direct without being rude. 6. **Break the limit when it should break:** legal or compliance messages, emotional support, first impressions, complex technical material, and personal notes where brevity reads as cold. 7. **Deliver ready-to-use text** with no placeholders. ## Contents - [references/coverage-map.md](references/coverage-map.md): where each part of the 1.0.0 text now lives (ruling D8). …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-concise-messaging@sha256:085f4e050e63bc29The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
