Applies a change-safety review to any requested file, mail or calendar change: lists every create, modify, move, rename, archive or delete before proposing it, marks destructive items as requiring the user's typed confirmation, proposes versioned file names instead of overwrites, declines to draft bulk destructive operations, and drafts a change journal entry for the user to keep. Use when the user asks to "clean up this folder", "delete the old versions", "reorganise these files…
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
# No-delete guardrail ## Purpose A guardrail, not a task. Once selected it applies three rules to every step in the conversation, including steps driven by other skills: nothing destructive is proposed for execution without the user's typed approval, no existing file is ever overwritten (a new versioned file is proposed instead), and every change is journalled in a table the user can audit. Be clear about the mechanism. The agent does not perform operations on the user's files, mail or calendar. It produces the exact list of actions for the user to perform and the full text of any new artefact. The guardrail is a behavioural commitment plus an audit journal, not an enforced control. It cannot intercept another skill, and an embedded instruction or a lapse can bypass any instruction, including this one. The journal exists so that what was proposed, approved, refused or left pending is visible afterwards. ## When to use …

How to install
mdr add kesslernity/awesome-copilot-agent-skills/no-delete-guardrail@sha256:fc0f73d568e543a6The line at the top of this page pins the label git:20260916.44af39e, 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.
