Global Blocks — AI skill for Claude Code

global-blocks

**Claims that survive crossing a boundary.**

A Claude Code plugin from [Playful Sincerity](https://playfulsincerity.org). It stores claims as **blocks** — addressable, versioned, hash-chained — hands them across boundaries as **portals** rather than copies, and pushes **corrections** to everyone who read the superseded version.

The part you feel first: put a block id in any file, and when an agent reads that file the claim arrives **filled in place** — the content replaces the id in the sentence that cites it, wrapped in who asserted it and how sure they were, with the id still visible. The file on disk never holds the content, so nothing copied can rot; and writing the file back contracts it to the bare id again, so an ordinary edit can't freeze a live claim into a dead copy. And if what you're holding is later corrected, you're told on your next turn, unasked, with the diff. *Unknown now, not false* — a withdrawn claim collapses to uncertainty, not to its opposite.

Changes, and the failure each fix came from: [`CHANGELOG.md`](CHANGELOG.md).

Look at your store

The store is plain markdown on your own disk — no database, no server. A reader ships inside the plugin:

BLOCKS="$(ls -d ~/.claude/plugins/cache/playful-sincerity/global-blocks/*/scripts/blocks | tail -1)"
$BLOCKS                  # every block, newest first
$BLOCKS tree             # the actual files — this IS the format
$BLOCKS log          # every version, and what changed
$BLOCKS board --serve    # the live audience board: who holds what, who is owed
