Best PromptsHandoff Skill
Compact the current conversation into a redacted handoff document a fresh agent can pick up: the bridge between context windows, in either direction.
--- name: handoff description: Compact the current conversation into a handoff document for another agent to pick up. argument-hint: "What will the next session be used for?" disable-model-invocation: true --- Write a handoff document summarising the current conversation so a fresh agent can continue the work. Save to the temporary directory of the user's OS - not the current workspace. Include a "suggested skills" section in the document, which suggests skills that the agent should invoke. Do not duplicate content already captured in other artifacts (specs, plans, ADRs, issues, commits, diffs). Reference them by path or URL instead. Redact any sensitive information, such as API keys, passwords, or personally identifiable information. If the user passed arguments, treat them as a description of what the next session will focus on and tailor the doc accordingly.
How to use
The answer to context windows filling mid-task: fork to a fresh session carrying a document, instead of compacting in place and losing the verbatim thread. The details are all load-bearing: saved outside the workspace so it never gets committed, references artifacts by path instead of duplicating them, redacts secrets, and takes an argument describing what the next session is for.
