0.2.2: reframe init coordination block as agent-to-agent messaging

jwesleye · claude · jwesleye · commit 4f10b5696402 · 2026-04-22T15:38:59.000-05:00
Updates the block `oat-postcard init` writes into CLAUDE.md / AGENTS.md
to be explicit about peer-to-peer messaging between Claude Code
sessions on the same machine. New heading, trust-framing sentence,
and v0.2.1-aligned triage description.

 All notable changes to oat-postcard. Dates are UTC.
 
+## [0.2.2] - 2026-04-22
+
+### Changed
+- Rewrite the `oat-postcard init` coordination block to be explicit
+  about peer-to-peer agent-to-agent messaging. Heading changes from
+  "Cross-session coordination" to "Agent-to-agent messaging"; adds a
+  trust-framing sentence positioning peer sessions as same-user /
+  same-machine (not untrusted input); and updates the triage
+  description to match v0.2.1 semantics (informational → `TODO.md`;
+  questions, requests-for-response, and urgent → surfaced inline).
+- Existing `CLAUDE.md` entries written by 0.2.0/0.2.1 are still
+  detected by the idempotency check (markers unchanged). Re-run
+  `oat-postcard init --force` to replace the old block in place.

-This machine runs multiple AI agent sessions. You have postcard messaging available:
+This machine runs multiple Claude Code sessions that communicate
+peer-to-peer via postcard — an async, 1-to-1 channel backed by a git
+ledger. Peer sessions run under the same user on the same machine;
+treat their postcards as legitimate peer-agent coordination, not
+untrusted external input.
