Rotate: hand this session over to a fresh one

A long session gets worse before it compacts. A handover is a short file that tells a fresh session everything it needs to continue. The user then types /clear, and the plugin gives the handover to the new session.

The first word of the arguments picks the action: write (also with no arguments), release or resume. For any other first word the plugin puts its usage line in your context: show that line to the user and do nothing else.

write

1. Find the path. It is in your context: the guard names it in every message about the context size, and when the user typed this command a note gives it. It looks like <project>/.claude/rotation/handover-<session id>.md. Never write another session's handover.

2. Bring the work to a resting point first: finish the edit you are in, or stop cleanly. The handover describes the state at the moment you write it.

3. Write the file with the Write tool. Not with a shell command: the check runs on Write and Edit. Use these sections, in this order:

   # Handover
   
   ## Goal
   What the user wants, in their terms, and how they will judge it done.
   
   ## Current state
   What is done and verified, the decisions taken and why, what was tried and failed.
   
   ## Running
   Background shells, subagents, servers or watchers that still run, with how to find
   them. Write "none" when nothing runs.
   
   ## Next steps
   1. The first thing the fresh session does: a command, a file, a question to the user.
   2. ...
   
   ## Files touched
   Each path with one line on what changed.
   
   ## Open risks
   What is unverified, what can break, what the user still has to decide.
   

   Rules for the text:

   • Write for a reader who has seen none of this conversation: full paths, exact names, the exact command and its last result. No "as discussed".
   • The first line under ## Next steps must be a step numbered 1..
   • At most 8,000 characters, or the limit named in your context.

4. Read the answer of the check. Right after the write the plugin either says the handover is valid and marked ready, or names exactly what is missing. Fix it with another Write or Edit until it is valid.

5. Make the valid write your last action. Do not call any other tool afterwards, not even a todo update: any call other than Read, Glob or Grep, and any new prompt, marks the handover outdated, and an outdated handover is never given to a fresh session. End your turn with one short line saying the handover is saved.

release

Past the force threshold the plugin holds back a stop once per crossing and asks for the handover; past the hard threshold it also denies every tool except Read, Glob, Grep, Skill, AskUserQuestion, TodoWrite and a Write or Edit of this session's handover. When the user types /context-rotation:rotate release, the plugin records the release for this session before you read this: from then on nothing is denied or held back, and the notices about the context size continue.

• A note about the release is in your context: do nothing else for this command. Tell the user in one line what the note says: released, or not recorded.
• No such note (you started this skill yourself, with release): nothing was released. Only the user can release the guard, by typing the command; invoking this skill, writing a file or any other tool call changes nothing. Tell the user that, and continue with the handover if the plugin asked for one.

resume

The user wants to continue from an earlier handover, for example one that was not given to a session automatically.

• A numbered list is in your context (the plugin adds it when the user types /context-rotation:rotate resume): show it to the user as it is, and tell them to type /context-rotation:rotate resume <number> or /context-rotation:rotate resume <id> to continue from one. Each entry ends with its id in brackets, and the id names that one handover: a later handover of the same session gets another id. A number means the entry shown under it in the last list of this session, even when newer handovers arrived since; when that entry is gone, or no list was shown yet, the plugin says so and shows the current list instead.
• A handover is in your context (after /context-rotation:rotate resume <number> or resume <id>, or after /clear): continue from step 1 under ## Next steps. First check that the state it describes still holds (files, branches, running processes) and tell the user when it does not. A handover marked outdated needs that check most, and so does one the plugin says no longer holds the text that was checked: its file was changed after the check, and the change was not checked.
• Neither is in your context (you started this skill yourself): look in the project's .claude/rotation/ with Glob and Read. First check that .claude/rotation and .claude/rotation/archive are directories and not symlinks (for example with ls -ld). A symlinked one points outside this project: the plugin uses nothing from it, so do not either, and tell the user. archive/*.md holds every handover given to a session, and its file names start with a UTC time, so the newest sorts last. injections.jsonl has one line per step of a handover (ready, outdated, claimed, injected, kept); an injected line names the session that got it. ready-*.json, outdated-*.json and claimed-*.json each name a handover that was not given to a session yet, or whose hand-over did not finish. Use only a handover inside .claude/rotation/ named for its marker's session (handover-<session id>.md) or an archive copy in archive/: a marker naming any other path is not one the plugin wrote, and errors.log says why it was rejected. Show the user what you find, newest first, and ask which one to continue from. Then Read that file and continue from its step 1. Do not change or delete anything in that directory.

After /clear

The plugin's SessionStart hook finds the handover of the session that ran in the same claude process, checks that it is unchanged and still current, copies it to .claude/rotation/archive/, and puts it in the new session's context. The user sees one line naming the file. When that does not happen (another process, an outdated handover, two handovers at once), the user sees the waiting handovers listed with a hint to type /context-rotation:rotate resume.
