Session Handoff 1.1.1

Full Changelog: v1.1.0...v1.1.1

Session Handoff 1.1.0

Session Handoff now preserves structured next actions, required sources, decision reasons, failed approaches, and open questions inside the checkpoint digest. A compact startup preview identifies omitted material, while the full checkpoint remains required before continuation.

Candidate acknowledgment must identify every required artifact and the exact first action, with matching host evidence, before ownership can transfer. Existing checkpoints remain compatible. These features are independently implemented from Engram's continuity ideas and require no Engram server or additional runtime dependencies.

This release also publishes the previously completed scoped Codex lifecycle hooks. Installing hooks does not grant trust or prove automatic handoff timing; those require validation in the host.

Validation: 24 Node tests passed, including lifecycle, malformed input, coverage, context gates, hooks, package integrity and standalone execution. The browser smoke passed in Chromium 153.0.8010.12 using synthetic host evidence. A bounded independent code review found no actionable defects. Complete automatic pre-compaction handoff is still unverified.

Download session-handoff.zip or session-handoff.skill to install, or use session-handoff.md in a text-only app. SHA256SUMS covers all three artifacts.

Session Handoff 1.0.1

The README now explains Session Handoff in everyday language, with simpler setup steps and a ready-to-copy message for your assistant. The original graphic is included, and developer details are tucked into an optional section.

The skill instructions and JavaScript code are unchanged. This update includes the new README in the download.

• session-handoff.zip — download this to install the skill.
• session-handoff.md — the full instructions to attach or paste into a chat.
• session-handoff.skill — the same package as the ZIP, with a different extension.
• SHA256SUMS — checksums for checking downloaded files.

Read the setup guide to get started.

Session Handoff 1.0

Session Handoff carries a task's goal, decisions, evidence, and unfinished work into a fresh AI conversation.

This release includes the rebuilt standalone skill, one shared JavaScript runtime for Node and browsers, and a redesigned README with an original hero illustration.

• The complete checkpoint, review, startup, and ownership instructions are in SKILL.md.
• Context checks use the host's actual compaction boundary and reserve space for the next action and handoff. Unknown telemetry triggers an early checkpoint.
• Native tools can perform the handoff where the host exposes the required controls and evidence. Text-only chats receive a complete manual continuation.
• Checkpoint integrity, exact goal and budget, candidate identity, stale acknowledgments, launch timeouts, and ownership transfer have dedicated runtime checks.

Download session-handoff.zip for a skill uploader, session-handoff.skill for tools using that extension, or session-handoff.md to attach or paste the instructions. The ZIP and .skill contain the same four files. SHA256SUMS provides their checksums.

Validation: 16 source/package tests passed; the same runtime was previously exercised in Chromium and through the installed package. The README was checked at desktop and mobile widths and in light/dark presentation using GitHub's Markdown renderer and stylesheets.

Automatic handoff still depends on the host's real session controls, telemetry, and coordinated state storage. No skill can guarantee pre-compaction timing on a host that hides the boundary or compacts without advance control.
