synthesis-inbox-cleanup skillB

synthesis-inbox-cleanup is agent-read markdown (skill) from synthesisengineering/synthesis-skills: Manifest-driven email inbox cleanup across three tool stacks: iCloud / generic IMAP via Python + YAML rules; Microsoft 365 + outlook.com via Mail.app AppleScript; Gmail via workspace-mcp Gmail API and server-side filters. Engine is public; per-user rules live privately at ~/.synthesis/inbox-cleanup/. Ships with prompt-injection defenses (sanitization module + adversarial test fixtures) for any LLM-augmented path. Use when asked to: clean up inbox, sweep email, categorize senders, build email rul.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add synthesisengineering/synthesis-skills/synthesis-inbox-cleanup@v1.6.2
Exact content
mdr add synthesisengineering/synthesis-skills/synthesis-inbox-cleanup@sha256:bedd1465d00f29ea

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
