Reviews the week ahead for double-bookings, meetings with no agenda or no decision to make, and lost focus time, then proposes specific changes without making any of them. Use when the user asks to review their calendar, find conflicts, protect focus time, says their week is overbooked, or wants to clean up next week.
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
# Calendar Defender Finds the week's conflicts and the meetings that should not exist, and proposes, never acts. ## Inputs - **Calendar Management** for the week ahead - **Email** and **Meetings** for whether an agenda exists and what each meeting is for - `references/config.md` for focus-time targets, working hours and meetings never touched ## Procedure 1. **Load the window** from config, normally the next seven days. 2. **Find hard conflicts**: overlapping accepted meetings. For each, say which has more attendees, which is recurring, and which has an agenda, so the user can choose. 3. **Find meetings with no stated purpose**: no agenda in the invitation, no linked document, no decision named. List them with the organiser, since the fix is usually a question to them, not a decline. 4. **Measure focus time**: unbroken blocks of the config minimum within working hours. Report the total against the target and name the days that have none. 5. **Find recurring meetings the user has not spoken in** for the config period, where transcripts exist. Report as a question, never as a recommendation to leave. …

How to install
mdr add kesslernity/awesome-copilot-cowork-bots/calendar-defender@sha256:0a5c81c828888ed6The line at the top of this page pins the label git:20261104.d10af7a, 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.
