A temporary conversation handoff writer for transferring work to another coding agent. It saves a compact Markdown file containing verified state, remaining work, constraints, decisions, and next steps.

Use it when explicitly transferring a session. It creates a uniquely named file in the system temporary directory, includes relevant available skills, verifies the file, reports its path, and stops.

A new agent may not have the earlier conversation and can otherwise repeat work or rely on unverified assumptions. The handoff preserves the operational context while excluding unnecessary secrets and personal details.

handoff — Skill for Claude Code and Codex by CHENyiru3

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add CHENyiru3/AI-Skills-Collections --skill handoff

Clone the repo

git clone --depth 1 https://github.com/CHENyiru3/AI-Skills-Collections

Made for: Claude Code, Codex.

Or install agents, the plugin that ships this one along with the rest of its 8 skills.

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	$0.00034	$0.00293
Opus 5.5	$0.00014	$0.00117
Sonnet 5.5	$0.00007	$0.00059
Haiku 4.5	$0.00003	$0.00029

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

Handoff

Use any supplied next-session focus to prioritize the context. Save a uniquely named handoff-*.md file in the operating system's reported temporary directory; return its absolute path. Do not overwrite a file or place the handoff in the workspace unless the user explicitly chooses another destination.

Capture the objective, verified current state, completed outcomes, remaining work, constraints, authorization, unresolved decisions, and concrete next steps. Separate assumptions and proposals from verified facts. Include exact commands only when they matter to continuation; link durable specs, reports, commits, and artifacts instead of repeating them.

Include a Suggested skills section naming only relevant skills actually available to the next agent. Tell it to load them using its supported skill mechanism; do not assume a tool literally named Skill. If none apply, say so.

Redact secrets and unnecessary personal/private identifiers. Preserve only operational identifiers needed to resume. Verify the handoff exists, report its path, and stop; creating a handoff does not authorize additional project work.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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 skill published in the GitHub repository CHENyiru3/AI-Skills-Collections (2 stars, last pushed 3d ago), licensed MIT. It adds 34 tokens to every session and 293 once invoked, about $0.0001 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 2026-11-13.
