Release the synthesis-skills plugin and keep skill installs true to source: one releaser at a time, push, install in Claude Code, Codex and Muse, verify installed bytes. Use to release, publish, install or update skills, check drift or provenance, or synthesis-merge a skill.
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
# Synthesis Skills Manager Skills are executable methodology kept in three source repositories (public, personal, team-shared). This skill releases the public plugin and keeps every installed copy equal to its source, resolving drift by synthesis merge in source rather than by overwriting. ## Binding rules 1. **Source is the only edit point.** Never edit an installed copy or a harness cache; edit, commit, push every configured remote, then install. Edits made anywhere else leave three states of the truth (2026-04-29). 2. **Push is part of the update, not a separate decision.** Permission to update a skill is permission to push its source; pausing between commit and push is the failure pattern. 3. **A release is done only when each harness's installed bytes equal the tag.** Pushing is publishing, harness installs do not follow the remote, and version labels lie (2026-08-24). 4. **One releaser at a time.** Claim the release train before authoring the version bump and hold it through the release; two sessions overtook each other five times on 2026-09-01. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-skills-manager@sha256:80adfd0f7f6a5250The line at the top of this page pins the label v3.3.3, 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.
