Handoff Skill: Keep Context Across Agent Sessions

Where this fits

You are halfway through a complex refactor, your context window is almost full, and a fresh agent needs to continue without you re-explaining everything. The handoff skill compacts the current conversation into a standalone document in your OS temp directory, so the next agent can pick up exactly where you left off.

Why agents benefit

• Reduces context loss: a concise handoff preserves decisions, constraints, and next steps without carrying the full raw transcript.
• Keeps the workspace clean: the document is written to the OS temporary directory, not into your repo or project folder.
• Points to existing artifacts: instead of repeating specs, plans, and diffs, the handoff references them by path or URL, avoiding duplication.
• Recommends next actions: a "suggested skills" section tells the next agent which Skill tool calls to make first.
• Protects sensitive data: API keys, passwords, and PII are redacted automatically in the generated document.

Practical scenarios

Long-running refactor across sessions

You spend three hours changing a payment service. Before your context resets, you call handoff with the argument "continue the refactor and update the affected tests." The next session starts with a temp file summarising the new interfaces, open files, and test gaps.

Bug handoff to a dedicated debugger

A support ticket reveals a race condition in the order worker. Instead of pasting logs and guesses, the handoff includes reproduction steps, relevant file paths, and the suggested debug-investigate skill for the next agent.

Multi-agent pipeline

Your orchestration agent detects token limits mid-task. It invokes handoff automatically, then a fresh agent reads the temp document, loads only the referenced artifacts, and continues with the planned next actions.

Add it to your agent workflow

Install the skill with:

npx skills add ArcReel/ArcReel --skill handoff

Then ask your agent:

Hand off to a fresh session focused on fixing flaky CI tests in the checkout flow.

The agent writes a compact handoff document to the OS temp directory, including a "suggested skills" section and links to existing commits or diffs.

Compare before adopting

Before committing, compare handoff with how you currently pass work between agents: manual summary prompts, shared notes, or commit messages. Check whether the generated document actually references artifacts instead of duplicating them, whether the "suggested skills" section matches your installed skills, and whether the repo stays actively maintained. Also consider simpler alternatives if your sessions are short and rarely cross context limits.

Why it is worth tracking

handoff is part of ArcReel, a repository with 4,310 stars, and it fits the automation category of agent skills. It is worth evaluating when you run multi-agent workflows or long sessions where context continuity is a bottleneck. The skill is deliberately lightweight: it does not create project files, does not leak sensitive information, and relies on the next agent to follow the referenced artifacts.
