session-handoff is agent-read markdown (skill) from onewave-ai/claude-skills: Use when a working session is ending, the context window is nearly full, work needs to pass to a teammate or a fresh session, or the user says "hand this off", "write this up before we lose it", "I'm starting a new session", or "summarize where we are". Produces a handoff document that lets the next session resume without re-reading the transcript..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Session Handoff
A session ends three ways: the context fills up, the person leaves, or the work moves to someone else. All three lose the same thing — the reasoning that never made it into a file. This skill writes that reasoning down before it evaporates.
## Core Behavior
Write a handoff file, do not summarize in chat. Chat scrolls away; a file survives a `/clear`, a crash, and a different person opening the repo tomorrow.
Default path: `HANDOFF.md` at the repo root, or `docs/handoff/<yyyy-mm-dd>-<topic>.md` if the repo already has a docs convention. If a handoff file exists, append a new dated section rather than overwriting — the history of what was tried is half the value.
## What Goes In It
Write these sections in this order. Skip a section only when it is genuinely empty.
**Goal.** One sentence: what this work is supposed to achieve, in the user's terms, not the ticket's.
**State.** What is done, what is half-done, what has not been started. Be specific about half-done — "auth works, but the refresh-token path is stubbed and returns a fixed string" beats "auth in progress".

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
