description

One-shot context-checkpoint workflow — when the current session is getting cluttered, write a structured handover plan capturing what's done and what's outstanding, then offer to spawn a fresh Claude session that opens already aware of the plan. Use when the user says "context is getting heavy", "let's checkpoint here", "stop, handover, restart", "context-gate", or otherwise signals they want to wrap the current session and continue cleanly in a new one.

Context Gate

A controlled checkpoint between sessions. When context gets cluttered or you've reached a natural pause, this skill orchestrates the three-step "stop → handover → resume cleanly" workflow as a single action so you don't have to remember each step or which skill to invoke.

Why use this

Long Claude sessions accumulate noise — exploratory tool calls, abandoned approaches, reasoning that's no longer load-bearing. A fresh session reading a tight handover plan starts faster, makes fewer mistakes, and costs less per turn than letting context drift toward the limit. This skill makes the swap a one-step action.

What it does

1. Pause the current session. Stop further work. Surface anything in flight that the new session needs to know.
2. Write a handover plan by delegating to handover-with-tasks (in this same plugin). The plan captures: what the user originally asked, what's been done, what's outstanding, any decisions made, any open questions, and any pitfalls discovered. Saved to a known location so the next session can find it.
3. Offer to spawn a fresh session that opens with the plan as context. Default form: a new terminal at the current working directory with the plan already passed as the first message. Delegate to new-claude-here (also in this plugin) with the plan path baked in.
4. Confirm the handoff. Show the plan path and the launch command. The user just approves; they're in a clean session in seconds.

The user types /claude-rudder:context-gate once. The orchestration happens behind that one entry point.

Inputs

The skill takes no required arguments. It infers what's relevant from the current conversation. Optional:

• --reason <text> — short note explaining why the user is checkpointing (e.g. "context cluttered after long migration debug"). Goes into the plan header.
• --no-resume — write the plan but don't offer to spawn a new session. User can launch later manually.
• --plan-path <path> — override where the plan is saved. Default per the resolver below.

Plan path resolver

Default location, in order of preference:

1. If cwd is inside a git repo → <repo-root>/planning/handovers/handover-<YYYY-MM-DD-HHMM>.md. Auto-run scaffold-planning first if planning/ is missing.
2. Else → ${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/claude-rudder/handovers/handover-<YYYY-MM-DD-HHMM>.md.

Use ISO-8601 minute resolution so multiple handovers per day sort cleanly.

Plan structure

Delegate authorship to handover-with-tasks but ensure the resulting plan has these sections (the existing skill should already produce most of them):

# Handover — <YYYY-MM-DD HHMM>

## Why this checkpoint
<one or two lines: the reason for stopping>

## Original ask
<what the user originally requested at the top of the session>

## Done
- <bullets of completed work, with file paths or commit hashes where useful>

## Outstanding
- <bullets of remaining tasks, ordered by priority>

## Decisions made
- <key choices: why this approach, what was rejected, any user calls>

## Open questions
- <things the new session should ask the user about, if any>

## Gotchas / pitfalls
- <surprises encountered, dead ends, things the new session shouldn't waste time on>

## Pointers
- Repo: <path>
- Branch: <name>
- Last commit: <sha + msg>
- Relevant files: <list>

Resume command

After writing the plan, print exactly one launch command the user can copy or approve, e.g.:

claude --message "Read $PLAN_PATH and continue from the Outstanding section. Ask me before doing anything destructive."

If the user agrees, delegate to new-claude-here with that message pre-filled. If they decline (--no-resume or "not yet"), just print the path and exit — they can resume any time.

Confirmation flow

After the plan is written, show:

✓ Handover plan written: <absolute path>
  Reason: <reason or "(none)">
  Outstanding items: <count>

Spawn a new Claude session pre-loaded with this plan? [Y/n]

If Y: launch via new-claude-here. If n: print the manual resume command and exit.

Hard rules

• Don't summarise speculatively. The handover should reflect what actually happened in this session, not what Claude thinks should happen next. If a decision is uncertain, mark it as an open question rather than committing to it.
• Don't include sensitive output. Strip tokens, API keys, raw credential values from any tool output quoted in the plan. References by env var name or op:// are fine.
• One plan per gate. Don't append to an existing plan — checkpoints are point-in-time snapshots. If the user wants a multi-day journal, that's a different workflow.
• Don't auto-launch. Always confirm before spawning a new session. The user might want to read the plan first.
