-description: Install or update ToolUniverse in Claude Science — create the conda env, install the tooluniverse pip package, and (re)build the tooluniverse-research skill by fetching the current workflow library from GitHub. Use for first-time setup, upgrading the ToolUniverse version, refreshing the bundled workflows after an upstream release, or reinstalling on a new machine.
----
-
-# Set up ToolUniverse for Claude Science
-
-The upstream ToolUniverse ships a Claude **Code** plugin (MCP server + `uvx` + slash commands). Claude **Science** loads capabilities differently, so this skill installs the equivalent natively: the `tooluniverse` **pip package** supplies the 2500+ tools, and the workflow library is packaged into a single dynamically-loaded skill, `tooluniverse-research`. No `uv`, no MCP server, no plugin marketplace.
-
-Loading this skill defines `tu_build_research_bundle()` in the kernel (run cells in the **`tooluniverse`** conda env).
-
-## Full install / update — four steps
-
-**1. Create the conda env** (skip if it already exists):
-```
-manage_environments(mode="create", name="tooluniverse", python_version="3.11", packages=["pip"])
-```
-
-**2. Install (or upgrade) the tools** — the pip package is the tool layer:
-```
-manage_packages(mode="install", environment="tooluniverse", packages=["tooluniverse"], use_pip=True)
-```
-Pin a version for reproducibility with `["tooluniverse==1.3.0"]`.
-
-**3. Stage the workflow bundle** — fetch the current repo and rebuild the file tree (run in a `python` cell, env `tooluniverse`):
-```python
-res = tu_build_research_bundle(staging="./tu_staging")
-res  # {out_dir, n_workflows, n_files, dropped, files_head}
-```
-This downloads the repo tarball, parses every `tooluniverse-*` workflow (dropping the plugin/installer entries), and writes `./tu_staging/out/` = `SKILL.md`, `kernel.py`, `index.json`, `workflows/*.md`.
-
-**4. Publish the skill** — push the staged tree into the catalog (run in the **`repl`** tool; `host.skills.*` lives there, not in `python`):
-```python
-import os
-SKILL = "tooluniverse-research"
-out = os.path.abspath("./tu_staging/out")
-if any(s["name"] == SKILL for s in host.skills.list()):
-    host.skills.delete(SKILL)                       # clean rebuild
-for root, _d, fs in os.walk(out):
-    for f in fs:
-        p = os.path.join(root, f)
-        rel = os.path.relpath(p, out)
-        host.skills.edit(SKILL, rel, open(p, encoding="utf-8").read())
-print(host.skills.publish(SKILL, overwrite=True))
-```
-(`host.skills.publish` refuses if `kernel.py` fails the sidecar gate — the `edit` result carries the verdict.)
-
-## Verify
-
-```python
-skill("tooluniverse-research")                      # loads router + injects helpers
-tu = get_tu()
-tu.run({"name": "PubChem_get_CID_by_compound_name", "arguments": {"name": "metformin"}})
-# -> {'status': 'success', 'data': {'IdentifierList': {'CID': [4091]}}}
-```
-
-## Notes
-
-- **Sandbox cache**: ToolUniverse defaults its cache to `~/.tooluniverse`, which is read-only here; `get_tu()` redirects it to the workspace via `TOOLUNIVERSE_CACHE_DIR`. Nothing to configure.
-- **API keys** (optional): most tools work without them. For NCBI / OncoKB / NVIDIA etc., add keys under Customize → Credentials, then expose them in the `tooluniverse` env.
-- **What is NOT ported**: the plugin's slash commands (`/tooluniverse:research`) and MCP server — replaced by natural-language routing (`search_skills` → `find_tu_workflow`). The two `*-plugin` installer docs are dropped as non-research entries.
-- **Updating**: rerun steps 2–4. Step 2 upgrades the tools; steps 3–4 refresh the workflow library from the latest GitHub state.

-# ToolUniverse Research
-
-Brings ToolUniverse's 2500+ scientific tools and 133 structured research workflows into Claude Science. The `tooluniverse` PyPI package supplies the tools; this skill bundles the workflows and a kernel sidecar that wires them up.
-
-## Setup
-
-Run all cells in the **`tooluniverse`** conda environment. Loading this skill auto-defines these helpers in the kernel:
-
-- `get_tu()` → a loaded `ToolUniverse` instance (cache redirected to the workspace, since `~/.tooluniverse` is read-only here).
-- `tu_workflows()` → list all 133 workflows (`name` + `description`).
-- `find_tu_workflow(query)` → rank workflows by relevance to a question.
-- `tu_workflow(name)` → the full step-by-step procedure for one workflow.
-- `tu_tool_info(tu, name)` → a tool's JSON spec, including its argument schema.
-
-## Answering a research question
-
-1. **Route** to a workflow: `find_tu_workflow("tell me about metformin")` returns ranked names. (Or browse `tu_workflows()`.)
-2. **Load** its procedure: `print(tu_workflow("tooluniverse-drug-research"))` and follow the steps.
-3. **Execute** the tools the workflow names. Every `ToolName(args)` reference maps to:
-   ```python
-   tu = get_tu()
-   tu.run({"name": "PubChem_get_CID_by_compound_name",
-           "arguments": {"name": "metformin"}})
-   ```
-4. **Confirm argument names** before a call if unsure — `tu_tool_info(tu, "PubChem_get_CID_by_compound_name")` shows the exact schema. Workflow prose abbreviates arguments; the schema is authoritative.
-5. **Discover tools** at runtime when no workflow fits:
-   ```python
-   tu.run({"name": "Tool_Finder_Keyword",
-           "arguments": {"description": "drug adverse events", "limit": 10}})
-   ```
-
-## Notes
-
-- Most tools work without API keys. A few (NCBI, OncoKB, NVIDIA, …) unlock enhanced access when keys are set in the env — add under Customize → Credentials, then expose them in the `tooluniverse` env.
-- Workflows are self-contained: report templates, checklists, and tool references are appended to each as appendices.
-- These workflows emphasize *looking things up* over recalling them — when a workflow says query a database, run the tool rather than answering from memory.
