setup-openhands

A repository setup guide for OpenHands, a coding-agent platform. It prepares instructions, startup scripts, pre-commit checks, and a pull-request review workflow based on the repository's real files and CI configuration.

In plain words
What is it for?
Use it to create `AGENTS.md`, configure session bootstrap and pre-commit scripts, install dependencies, set environment variables, and mirror the checks used in continuous integration.
Why use it?
It reduces setup work and helps the agent use the same installation, linting, and testing commands as the project itself.

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.

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

setup-openhands 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 2d 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.

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

Set Up OpenHands for a Repository

Work through these steps in order.

Step 1: Create AGENTS.md

Run setup-agents-md to generate a root-level AGENTS.md from the repo's actual CI workflows, build files, and documentation.

Step 2: Create .openhands/setup.sh

Create .openhands/setup.sh — a bootstrap script that runs at the start of every OpenHands session. Read the repo's CI workflows, AGENTS.md, and build files to determine the correct commands. The script should:

  • Install dependencies (the project's actual install command)
  • Set required environment variables
  • Run any other bootstrap steps (e.g. copy .env.example to .env)

Keep it idempotent and fast. Use the real commands from CI, not generic examples.

Docs: https://docs.openhands.dev/openhands/usage/customization/repository#setup-script

Step 3: Create .openhands/pre-commit.sh

Create .openhands/pre-commit.sh — runs before every commit OpenHands makes. Read the repo's CI workflows to find the lint and test commands, then mirror them in the script. Exit non-zero on failure so the agent gets immediate feedback instead of waiting for CI.

The script should run the same checks CI runs — if CI runs ruff check and pytest, run those. If it runs cargo clippy and cargo test, run those.

Docs: https://docs.openhands.dev/openhands/usage/customization/repository#pre-commit-script

Step 4: Set up PR review

Run setup-pr-review to create the GitHub Actions workflow and walk the user through configuration.

Step 5: Verify

Confirm all files exist and are correct:

  • AGENTS.md at repo root with real commands (not boilerplate)
  • .openhands/setup.sh with the project's actual install/bootstrap commands
  • .openhands/pre-commit.sh mirroring the CI lint/test checks
  • .github/workflows/pr-review.yml with valid YAML
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.

setup-openhands is a skill published in the GitHub repository OpenHands/extensions (137 stars, last pushed 4d ago), licensed MIT. It adds 55 tokens to every session and 525 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
