A command for handing ongoing work to a fresh coding session. It sends an optional note and lets the next session continue from the saved work state.

Use it when work is unfinished, a session is being rotated, or another agent needs to take over.

It avoids losing context when a session must end or be replaced. The next session can find the handoff message instead of starting from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00010	$0.00145
Opus 5.5	$0.00004	$0.00058
Sonnet 5.5	$0.00002	$0.00029
Haiku 4.5	$0.00001	$0.00015

Security

Grade A, and why

handoff scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Hand off to a fresh session.

User's handoff message (if any): $ARGUMENTS

Execute these steps in order:

If user provided a message, run the handoff command with a subject and message: gt handoff -y -s "HANDOFF: Session cycling" -m "USER_MESSAGE_HERE"
If no message was provided, run the handoff command: gt handoff -y

Note: The new session will auto-prime via the SessionStart hook and find your handoff mail. End watch. A new session takes over, picking up any molecule on the hook.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

handoff is a command published in the GitHub repository BlackbirdWorks/gopherstack (17 stars, last pushed yesterday), licensed MIT. It adds 10 tokens to every session and 145 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-07.
