codex-handoff: Design & UI for AI Agents | OpenAgentSkill

Overview

Roll an oversized or slow Codex task into a fresh user-visible task with compact continuity. Use only for an explicit handoff or context rollover; not for ordinary continuation, delegation, full-history forks, Git migration, or handoff files.

Codex Handoff

Preconditions

Explicit invocation approves one user-owned task. Arguments set its focus; otherwise recover the current objective from verified context.
Require list_projects and create_thread. If unavailable, stop; do not substitute a shell command or Markdown file.

Build the continuity prompt

Write a self-contained prompt of roughly 2,000–4,000 Chinese characters or comparable size. Prefer smaller when links carry detail. Include:

objective and first action;
completed work and current state;
decisions, constraints, and material rejected alternatives;
authoritative files, plans, issues, commits, diffs, or URLs;
verification performed and failures observed;
remaining work, blockers, fragile state, and transient paths;
relevant installed Skills.

Point to authoritative artifacts instead of reproducing them. Omit transcript history, large diffs or status output, repeated reasoning, secrets, credentials, and unrelated personal information. Mark transient paths as fragile. End with: read active instructions, verify current state, and begin the first action now.

Create the fresh task

Resolve the current saved project with list_projects; obey project and host environment rules. Never guess another project or silently fall back to projectless. If the target omits material uncommitted state, stop and state the risk.
Call create_thread with the compact prompt. Omit model and reasoning overrides unless explicitly requested.
For a ready threadId, title it with set_thread_title and take one bounded wait_threads snapshot; do not wait for completion. For only clientThreadId, report setup as queued, not running.
Return a one-line summary and the created-task directive. Claim only the returned state.
Stop work in the old task. Keep it as history; do not archive it or keep editing the shared workspace.

Exclusions

Do not use fork_thread; full-history copies defeat the context reset.
Do not spawn a subagent; delegation is not a user-owned continuation task.
Do not use handoff_thread; it moves another task's Git environment.
Do not create or resume a handoff document; that is a file-oriented workflow.
Do not trigger on ordinary requests to continue in the current task.

Maintain the manual trigger boundary with evals/trigger_cases.json and the continuity behavior with evals/output/cases.jsonl.

# Codex Handoff

## Preconditions

- Explicit invocation approves one user-owned task. Arguments set its focus; otherwise recover the current objective from verified context.
- Require `list_projects` and `create_thread`. If unavailable, stop; do not substitute a shell command or Markdown file.

## Build the continuity prompt

Write a self-contained prompt of roughly 2,000–4,000 Chinese characters or comparable size. Prefer smaller when links carry detail. Include:

- objective and first action;
- completed work and current state;
- decisions, constraints, and material rejected alternatives;
- authoritative files, plans, issues, commits, diffs, or URLs;
- verification performed and failures observed;
- remaining work, blockers, fragile state, and transient paths;
- relevant installed Skills.

## Create the fresh task

1. Resolve the current saved project with `list_projects`; obey project and host environment rules. Never guess another project or silently fall back to projectless. If the target omits material uncommitted state, stop and state the risk.
2. Call `create_thread` with the compact prompt. Omit model and reasoning overrides unless explicitly requested.
3. For a ready `threadId`, title it with `set_thread_title` and take one bounded `wait_threads` snapshot; do not wait for completion. For only `clientThreadId`, report setup as queued, not running.
4. Return a one-line summary and the created-task directive. Claim only the returned state.
5. Stop work in the old task. Keep it as history; do not archive it or keep editing the shared workspace.

## Exclusions

- Do not use `fork_thread`; full-history copies defeat the context reset.
- Do not spawn a subagent; delegation is not a user-owned continuation task.
- Do not use `handoff_thread`; it moves another task's Git environment.
- Do not create or resume a handoff document; that is a file-oriented workflow.
- Do not trigger on ordinary requests to continue in the current task.

Maintain the manual trigger boundary with `evals/trigger_cases.json` and the continuity behavior with `evals/output/cases.jsonl`.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: MIT

Dependency or permission surface needs review
Permission surface may require sandboxing
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Dependency/runtime risk: command execution surface, credential or environment access
Permission surface: secrets or environment access, shell or command execution

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
