pan handoff
Create a new conversation seeded by a handoff document written by the live source agent.
Quick command
pan handoff [conv] [focus text...]
The trailing text after the conversation reference becomes the focus — no flag required.
⚠️ The focus MUST be ≤ 500 characters. A longer focus is rejected outright with Fork request rejected: focus must be 500 characters or fewer and no conversation is created — so count it and keep it under 500 on the first try. Keep the focus short and steering; do NOT pack backstory/context into it — the author reads the full source transcript for that. This is the single most common handoff mistake.
Handing off the conversation you are in (the common case)
If you are an agent inside a conversation and want to hand off your own
conversation, omit <conv> — or pass self. Do NOT run pan conv scan,
pan conv list, or pan conv show to "find yourself" and then guess an id.
That scan-and-guess pattern picks the wrong source (PAN-1520); the command
identifies your conversation deterministically from the session you are running
in.
pan handoff
pan handoff self wire the Stripe webhook
Because focus text is positional, prefer the explicit self token whenever you
pass focus — a bare first word like pan handoff continue the wiring is
interpreted as a conversation reference named "continue", not focus. self
removes the ambiguity.
If you want to know which conversation you are resolved to, run pan conv current
(alias pan conv whoami). It prints the deterministic answer with no guessing.
Self-detection works for non-Docker claude-code conversations. If it cannot
resolve (run outside a conversation, or a Docker workspace), the command errors
and asks for an explicit <conv> — it never falls back to a guess.

Issue association
Use --issue <id> to attach the new conversation to a specific issue (e.g. PAN-1234). The flag is validated; an invalid ID rejects the request and creates no conversation. When --issue is omitted, the new conversation inherits the source conversation's issue association, if any.
When to use
- A long-running conversation is near the context wall.
- The current agent knows dead ends, hazards, or file relationships that a passive summary may miss.
- You want a deliberate context transfer before switching models, harnesses, or tasks.
Use a normal summary fork when a quick passive summary is enough. Use a plain fork only when staying within Claude Code-compatible raw history.
Focus
The positional text after <conv> is the focus — a short statement of what the successor should concentrate on. Quotes are optional; everything after the conversation reference (excluding flags) is joined with spaces. Keep it short and task-oriented; the focus is injected into the handoff-authoring prompt, not used as the new conversation's user request.
Hard limit: the focus must be ≤ 500 characters. A longer focus is rejected outright with Fork request rejected: focus must be 500 characters or fewer and no conversation is created — so write it under 500 chars on the first try. Don't pack the backstory into the focus; the detail belongs in the transcript the author reads. The focus only steers what the author emphasizes.
Authoring modes
--author external (default) spawns a separate authoring session that reads the source JSONL transcript and writes the handoff document. The source conversation is never contacted — its context stays clean, and the source can be ended. Use --author-model and --author-harness to choose the authoring model and harness independently of the source and of the new conversation. Cheaper models work well for routine handoffs; reach for a larger model when the conversation has nuance the document needs to preserve.
--author source asks the live source agent to write the handoff document in-conversation. This adds the prompt and the doc to the source's transcript (polluting its context) and uses whatever model the source is currently running. It can still be the right choice when the source agent has live state — open files, recent commands, in-flight reasoning — that a transcript reader would miss.
Fallback behavior
pan handoff <conv> always attempts to create a usable new conversation. If the live-agent handoff cannot complete, Overdeck falls back to a summary fork and prints the fallback reason. An oversized source conversation is never a hard failure: it is auto-degraded through a truncated smart summary, then a heuristic fallback, then a focus-only seed, and the handoff still spawns.
Common fallback reasons:
source-ended — the source conversation is already ended.handoff-timeout — the source did not write both the document and .done sentinel in time.handoff-validation — the document did not satisfy the handoff contract.source-workspace-devcontainer — the source cannot write to the host handoff directory from a workspace container.handoff-request-failed — the authoring request failed (e.g., context overflow) and the system fell back to a degraded summary.
Output
Successful handoffs print the new conversation id, tmux session, model, harness, dashboard link, and handoff doc path. Fallbacks print the same new conversation details plus a yellow fallback notice.
