feat(skills): add optional openhands skill — closes #477

Adds an optional autonomous-ai-agents skill that delegates coding tasks
to the OpenHands CLI (https://github.com/All-Hands-AI/OpenHands). Sits
alongside claude-code / codex / opencode and is the model-agnostic
option in that family — any LiteLLM-supported provider works.

This is a ground-truth rewrite of #19325 by @xzessmedia (Tim Koepsel).
The original PR's SKILL.md was drafted by the OpenHands agent itself and
hallucinated several flags that don't exist in the real CLI (\`--model\`,
\`--max-iterations\`, \`--workspace\`, \`--sandbox docker\`), pointed at
the wrong PyPI package (\`openhands-ai\`, which is the legacy V0 SDK),
and claimed native Windows support that the upstream docs explicitly
disclaim. Rather than cherry-pick and rewrite half the lines under
contributor authorship, the SKILL.md was rebuilt against a verified
install (\`uv tool install openhands --python 3.12\`) and a real
end-to-end \`--headless --json\` run against openrouter/openai/gpt-4o-mini.

Authorship credited via the \`author:\` frontmatter field and an
AUTHOR_MAP entry in scripts/release.py.

Changes:
- optional-skills/autonomous-ai-agents/openhands/SKILL.md (new)
- website/docs/user-guide/skills/optional/autonomous-ai-agents/autonomous-ai-agents-openhands.md (auto-gen)
- website/docs/reference/optional-skills-catalog.md (one new row)
- website/sidebars.ts (one new entry under Optional → Autonomous AI Agents)
- scripts/release.py (AUTHOR_MAP entry for xzessmedia)

Pitfalls documented in the SKILL came from running the tool, not from
the upstream README: LiteLLM bedrock/sagemaker stderr noise on every
invocation, banner spam (\`OPENHANDS_SUPPRESS_BANNER=1\` required),
\`--override-with-envs\` mandatory or the CLI ignores LLM_* env vars
entirely, the dashed-vs-undashed Conversation ID footgun for \`--resume\`,
LiteLLM model-slug double-prefix when going through OpenRouter.

# OpenHands CLI
Delegate coding tasks to the [OpenHands CLI](https://github.com/All-Hands-AI/OpenHands) via the `terminal` tool. OpenHands is model-agnostic: any LiteLLM-supported provider (OpenAI, Anthropic, OpenRouter, DeepSeek, Ollama, vLLM, etc.).
This skill is the headless-mode wrapper for batch / one-shot delegation. The interactive textual UI is not used from Hermes.
## When to Use
- User wants a coding task delegated to OpenHands specifically.
- User wants a coding agent that can run on a non-Anthropic / non-OpenAI provider (DeepSeek, Qwen, Ollama, vLLM, Nous, etc.) — sibling skills `claude-code` and `codex` are tied to one vendor.
- Multi-step file edits + shell commands inside a workspace.
For Claude-native, prefer `claude-code`. For OpenAI-native, prefer `codex`. For Hermes-native subagents, use `delegate_task`.
## Prerequisites
1. Install upstream (requires Python 3.12+ and `uv`):
```
terminal(command="uv tool install openhands --python 3.12")
```
Verify: `openhands --version` (currently `OpenHands CLI 1.16.0` / `SDK v1.21.0` at time of writing).
2. Pick a model and set env vars for `--override-with-envs`:
```
export LLM_MODEL=openrouter/openai/gpt-4o-mini # or any LiteLLM slug
export LLM_API_KEY=$OPENROUTER_API_KEY
export LLM_BASE_URL=https://openrouter.ai/api/v1 # omit for native OpenAI
```
`LLM_MODEL` uses LiteLLM's full slug. When the provider is OpenRouter the slug is doubly-prefixed: `openrouter/<vendor>/<model>` (e.g. `openrouter/anthropic/claude-sonnet-4.5`). For native Anthropic: `anthropic/claude-sonnet-4-5`. For native OpenAI: `openai/gpt-4o-mini`.
3. Suppress the startup banner so JSON output isn't preceded by ASCII art:
```
export OPENHANDS_SUPPRESS_BANNER=1
```
## How to Run
Always invoke through the `terminal` tool. Always pass `--headless --json --override-with-envs --exit-without-confirmation` for automation.
### One-shot task
```
terminal(
command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Add error handling to all API calls in src/'",
workdir="/path/to/project",
timeout=600
)
```
### Background for long tasks
```
terminal(command="<same as above>", workdir="/path/to/project", background=true, notify_on_complete=true)
process(action="poll", session_id="<id>")
process(action="log", session_id="<id>")
```
### Resume a previous conversation
OpenHands prints `Conversation ID: <32-hex>` and a `Hint: openhands --resume <dashed-uuid>` line at the end of each run. Use the dashed form to resume:
```
terminal(
command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=... openhands --headless --json --override-with-envs --exit-without-confirmation --resume <dashed-uuid> -t 'Now fix the bug you found'",
workdir="/path/to/project"
)
```
## Real Flag List
Verified against `openhands --help` (CLI 1.16.0). Anything not in this table is not a flag — pass it via env var or settings file.
| Flag | Effect |
|------|--------|
| `--headless` | No UI, requires `-t` or `-f`. Auto-approves all actions (no `--llm-approve` in this mode). |
| `--json` | JSONL event stream (requires `--headless`). |
| `-t TEXT` | Task prompt. |
| `-f PATH` | Read task from file. |
| `--resume [ID]` | Resume conversation. No ID → list recent. |
| `--last` | Resume most recent (with `--resume`). |
| `--override-with-envs` | Apply `LLM_API_KEY` / `LLM_BASE_URL` / `LLM_MODEL` env vars. Without this, OpenHands uses `~/.openhands/settings.json` and ignores the env. |
| `--exit-without-confirmation` | Don't show the "are you sure" exit dialog. |
| `--always-approve` / `--yolo` | Auto-approve every action (default in `--headless`). |
| `--llm-approve` | LLM-based security gate (interactive only — does NOT work in headless). |
| `--version` / `-v` | Print version and exit. |
**There is no `--model`, `--max-iterations`, `--workspace`, `--sandbox`, `--sandbox-type` flag.** Model is `LLM_MODEL`. Workspace is the `workdir` you pass to the `terminal` tool. Sandbox / runtime is the `RUNTIME` and `SANDBOX_VOLUMES` env vars.
## JSON Event Schema
With `--json --headless`, OpenHands emits JSONL — one JSON object per line, plus a handful of non-JSON status lines (`Initializing agent...`, `Agent is working`, `Agent finished`, the final summary box, `Goodbye!`, `Conversation ID:`, `Hint:`). Filter for lines starting with `{`.
Top-level `kind` field discriminates events:
- `MessageEvent` — user / agent text turn. `source` is `user` or `agent`.
- `ActionEvent` — agent picked a tool. Read `tool_name` (`file_editor`, `terminal`, `finish`) and `action.kind` (`FileEditorAction`, `TerminalAction`, `FinishAction`).
- `ObservationEvent` — tool result. `observation.is_error` is the success flag. `source` is `environment`.
- `FinishAction` inside an `ActionEvent` carries the agent's final message in `action.message`.
The cli prints all stderr from LiteLLM/Authlib first — see Pitfalls. Parse only stdout, line by line, ignoring lines that don't start with `{`.
## Pitfalls
- **LiteLLM warnings on every invocation.** The CLI prints `bedrock-runtime` and `sagemaker-runtime` warnings to stderr because `botocore` isn't installed. Plus an Authlib deprecation. These are noise, not failures. Pipe stderr to `/dev/null` or filter it out before showing the user.
- **Banner spam.** Without `OPENHANDS_SUPPRESS_BANNER=1`, every run starts with a multi-line `+--+` ASCII box advertising the SDK. Always export it.
- **`--override-with-envs` is mandatory for automation.** Without it, OpenHands ignores `LLM_API_KEY` / `LLM_BASE_URL` / `LLM_MODEL` and falls back to `~/.openhands/settings.json`. On a fresh install this file doesn't exist and the CLI hangs waiting for first-run setup.
- **Model slug is LiteLLM's, not the provider's.** `openrouter/openai/gpt-4o-mini` works; `openai/gpt-4o-mini` while pointed at OpenRouter does not. `anthropic/claude-sonnet-4-5` (hyphen) is native Anthropic; `openrouter/anthropic/claude-sonnet-4.5` (dot) is via OpenRouter. Get it wrong → cryptic LiteLLM 400.
- **`pip install openhands-ai` is the wrong package.** That's the legacy V0 SDK. The new CLI is `uv tool install openhands --python 3.12`. There is no maintained conda package.
- **Resume ID format is fiddly.** The CLI ends with `Conversation ID: f46573d9cfdb45e492ca189bde40019b` (no dashes) and then a `Hint: openhands --resume f46573d9-cfdb-45e4-92ca-189bde40019b` (with dashes). Use the dashed form.
- **Headless ignores `--llm-approve`.** If you pass it, you get an argparse error. Headless mode hardcodes always-approve.
- **No Windows support upstream.** The OpenHands docs require WSL on Windows. This skill is gated `[linux, macos]` accordingly.
- **`~/.openhands/conversations/<id>/` accumulates.** Each run persists a trajectory. Clean it up if running batches.
- **Heavy install (~200 packages).** Use `uv tool install` (isolated venv) to avoid dependency conflicts with the active project.
## Verification
```
terminal(
command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Print the string OPENHANDS_OK to stdout via the terminal tool.'",
workdir="/tmp",
timeout=120
)
```
If the JSONL stream ends with a `FinishAction` whose `action.message` mentions `OPENHANDS_OK`, the install is working.

# OpenHands CLI
Delegate coding tasks to the [OpenHands CLI](https://github.com/All-Hands-AI/OpenHands) via the `terminal` tool. OpenHands is model-agnostic: any LiteLLM-supported provider (OpenAI, Anthropic, OpenRouter, DeepSeek, Ollama, vLLM, etc.).
This skill is the headless-mode wrapper for batch / one-shot delegation. The interactive textual UI is not used from Hermes.
## When to Use
- User wants a coding task delegated to OpenHands specifically.
- User wants a coding agent that can run on a non-Anthropic / non-OpenAI provider (DeepSeek, Qwen, Ollama, vLLM, Nous, etc.) — sibling skills `claude-code` and `codex` are tied to one vendor.
- Multi-step file edits + shell commands inside a workspace.
For Claude-native, prefer `claude-code`. For OpenAI-native, prefer `codex`. For Hermes-native subagents, use `delegate_task`.
## Prerequisites
1. Install upstream (requires Python 3.12+ and `uv`):
```
terminal(command="uv tool install openhands --python 3.12")
```
Verify: `openhands --version` (currently `OpenHands CLI 1.16.0` / `SDK v1.21.0` at time of writing).
2. Pick a model and set env vars for `--override-with-envs`:
```
export LLM_MODEL=openrouter/openai/gpt-4o-mini # or any LiteLLM slug
export LLM_API_KEY=$OPENROUTER_API_KEY
export LLM_BASE_URL=https://openrouter.ai/api/v1 # omit for native OpenAI
```
`LLM_MODEL` uses LiteLLM's full slug. When the provider is OpenRouter the slug is doubly-prefixed: `openrouter/<vendor>/<model>` (e.g. `openrouter/anthropic/claude-sonnet-4.5`). For native Anthropic: `anthropic/claude-sonnet-4-5`. For native OpenAI: `openai/gpt-4o-mini`.
3. Suppress the startup banner so JSON output isn't preceded by ASCII art:
```
export OPENHANDS_SUPPRESS_BANNER=1
```
## How to Run
Always invoke through the `terminal` tool. Always pass `--headless --json --override-with-envs --exit-without-confirmation` for automation.
### One-shot task
```
terminal(
command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=openrouter/openai/gpt-4o-mini LLM_API_KEY=$OPENROUTER_API_KEY LLM_BASE_URL=https://openrouter.ai/api/v1 openhands --headless --json --override-with-envs --exit-without-confirmation -t 'Add error handling to all API calls in src/'",
workdir="/path/to/project",
timeout=600
)
```
### Background for long tasks
```
terminal(command="<same as above>", workdir="/path/to/project", background=true, notify_on_complete=true)
process(action="poll", session_id="<id>")
process(action="log", session_id="<id>")
```
### Resume a previous conversation
OpenHands prints `Conversation ID: <32-hex>` and a `Hint: openhands --resume <dashed-uuid>` line at the end of each run. Use the dashed form to resume:
```
terminal(
command="OPENHANDS_SUPPRESS_BANNER=1 LLM_MODEL=... openhands --headless --json --override-with-envs --exit-without-confirmation --resume <dashed-uuid> -t 'Now fix the bug you found'",
workdir="/path/to/project"
)
```

- **Model slug is LiteLLM's, not the provider's.** `openrouter/openai/gpt-4o-mini` works; `openai/gpt-4o-mini` while pointed at OpenRouter does not. `anthropic/claude-sonnet-4-5` (hyphen) is native Anthropic; `openrouter/anthropic/claude-sonnet-4.5` (dot) is via OpenRouter. Get it wrong → cryptic LiteLLM 400.
- **`pip install openhands-ai` is the wrong package.** That's the legacy V0 SDK. The new CLI is `uv tool install openhands --python 3.12`. There is no maintained conda package.

## Verification
```
terminal(

workdir="/tmp",
timeout=120
)
```
If the JSONL stream ends with a `FinishAction` whose `action.message` mentions `OPENHANDS_OK`, the install is working.
