devin-handoff: Instructions file for Codex

AGENTS.md

devin-handoff AGENTS.md is an instructions file for Codex, OpenCode from club-cog/devin-handoff. It costs 542 tokens per session, scanned A, original, MIT.

A handoff guide for sending a coding task to Devin, a cloud-based AI software engineer. It explains when work needs a virtual machine, browser, CI system, deployment environment, or long-running execution.

In plain words
What is it for?
Handing off server or Docker work, browser and end-to-end tests, OAuth flows, CI/CD debugging, deployments, migrations, large refactors, or parallel work.
Why use it?
It helps move tasks that cannot be completed conveniently in the current environment to a place with the needed resources. It also gives the handoff script and the information to include.

Written for Codex and OpenCode: the file is AGENTS.md.

This is club-cog/devin-handoff's own configuration. It tells Codex and OpenCode how to work on devin-handoff itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything devin-handoff configures →

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.

Security

Grade A, and why

devin-handoff AGENTS.md scanned grade A with 1 finding 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 9d ago.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Devin Handoff — Agent Guide

What this is

A script to hand off tasks to Devin, a cloud AI software engineer. Use it when a task needs a VM, browser, CI, or long-running execution.

When to hand off

  • VM / server: Running a dev server, testing endpoints, Docker builds
  • Browser: Screenshots, OAuth flows, E2E testing, scraping
  • CI/CD: Pipeline debugging, deployment, infrastructure changes
  • Long-running work: Migrations, batch processing, large refactors
  • Parallel execution: Offload work while you continue locally

Finding the script

scripts/devin-handoff.sh below refers to wherever the script lives in your setup. Check, in order:

  1. scripts/devin-handoff.sh in the current repo
  2. An installed devin-handoff skill or plugin (the script sits next to its SKILL.md, e.g. .agents/skills/devin-handoff/scripts/devin-handoff.sh)
  3. If neither exists, clone it: git clone https://github.com/club-cog/devin-handoff.git

How to use

  1. Gather context from the current repo (the script does this automatically)
  2. Summarize what you've learned so far as --context
  3. Run:
scripts/devin-handoff.sh create \
  --task "<concise task description>" \
  --context "<what you've found so far>"
  1. Share the session URL with the user
  2. To wait for completion, poll until Devin finishes:
scripts/devin-handoff.sh poll SESSION_ID --interval 15

The poll command prints status updates every N seconds and exits when Devin finishes (exit/error/suspended) or reaches waiting_for_user — meaning Devin has stopped working and is waiting on a message from you, which for a handoff counts as done. It prints the PR URL if one was created.

  1. To archive the session when done:
scripts/devin-handoff.sh archive SESSION_ID --org-id ORG_ID

Or auto-archive after polling: add --archive --org-id ORG_ID to the poll command.

Requirements

  • DEVIN_API_KEY environment variable must be set
  • curl and jq must be available
  • git is optional (for automatic repo/branch/diff detection)

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.
