+## 2026-07-25 — Copyable local-agent issue handoffs
+
+- Added a compact issue-header action that copies the issue key, title, and
+  canonical human-readable URL for use in a local agent task.
+- Included a concise Forge MCP workflow contract in the copied reference:
+  reconcile Delivery ownership before acting, use one isolated code-delivery
+  path, attach one native implementation PR, report meaningful lifecycle
+  updates, and preserve explicit merge/release/deploy authority.
+- Added unit coverage for the generated contract and Playwright coverage for
+  the browser clipboard interaction.

+## Local-agent handoff
+
+Use **Copy handoff** in the issue header when you want to continue an issue in a
+local agent task. Forge copies the issue key and title, its canonical
+human-readable link, and a short workflow contract for the receiving agent.
+
+The contract tells the agent to use Forge MCP as delivery truth, inspect the
+current Delivery session before acting, continue or explicitly
+claim/join/handoff ownership, work from one isolated issue branch and worktree,
+link one primary PR through the native `IMPLEMENTS` relation, report meaningful
+lifecycle updates, and finish the run visibly. It also preserves the operator
+boundary around merge, release, and deployment. The title is explicitly marked
+as reference data so issue content does not become operational instruction.
+
+This clipboard reference does not change assignment, start a run, or transfer
+Delivery ownership. The receiving agent must reconcile those facts through
+Forge rather than treating the pasted prompt as authority.
+
 ## The two assignment slots
 
 Forge keeps human and agent assignment **independent**. An issue can have:
