## What it does

This skill gives the agent a route into GXL Paperclip, a CLI plus Python SDK that serve scientific literature through a virtual filesystem. Every search is scoped to a source such as `pmc`, `fda` or `trials/us`. From there you get `grep` over full text, `lookup doi`, SQL against metadata and `scan` for key terms. It is GXL Paperclip, not the unrelated app of the same name built around agent-run companies.

The package ships `SKILL.md` with worked call sequences and reference files for installation, retrieval, map/reduce and the SDK. Working across several papers means `filter` to narrow a saved cohort, then `map --from s_ID` to pull the same fields from each hit, with `reduce --strategy table` for the summary. Those readers are LLM output, so check pinned source lines before you repeat a number or quote.

Network access and the CLI come first. On macOS and Linux the installer wants Python 3.8+ plus `curl` or `wget`, and it installs a launcher and private library rather than an interpreter. Credentials come from `PAPERCLIP_API_KEY` or a browser login, and a project `.env` is never loaded automatically — sourcing one runs shell code, so keep that file trusted and out of Git.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill paperclip -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/paperclip/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/paperclip/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill paperclip -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/paperclip/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill paperclip -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/paperclip/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install K-Dense-AI/scientific-agent-skills paperclip
```

2. **Manually: put the files in place**
- File: `.github/skills/paperclip/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill paperclip -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/K-Dense-AI/scientific-agent-skills --path skills/paperclip
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/paperclip/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill paperclip -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/K-Dense-AI/scientific-agent-skills/tree/HEAD/skills/paperclip/SKILL.md

## When to use it
- pull a handful of PMC papers on a delivery method
- grep a full text for one exact gene name
- resolve a DOI before reading the paper
- extract the same fields across a set of papers
- read FDA approval documents for a drug

## Example prompts
- Search `pmc` for five papers on lipid nanoparticle mRNA delivery and grep the text for IC50
- Map delivery vector, target cell type and efficiency across that saved search set
- Look up NCT04752059 in `trials/us` and show the trial metadata

# Paperclip CLI

Paperclip by GXL exposes scientific documents through a virtual filesystem and server-side search
and readers. This is **GXL Paperclip** at `paperclip.gxl.ai`, not the unrelated Paperclip agent-company
application. Use the source requested by the user; other providers have their own skills.

This revision checks official docs, the public API schema, and installed CLI/SDK **0.7.92**.
Local help, SDK request construction, and public metadata were checked. Authenticated retrieval,
LLM readers, uploads, and repository mutations were not run during this review; their examples
are illustrative. Server behavior can change independently of the CLI version.

## Preflight and authentication

```bash
command -v paperclip
paperclip --version
paperclip --help
```

If installed, use the existing account or a key configured privately at
`https://paperclip.gxl.ai/keys`. Do not ask for a key in chat or print credential files.
Paperclip does not automatically load a project `.env`. If the user has supplied a **trusted,
shell-compatible** `.env`, export it in the same shell invocation as the command:

```bash
if [ -f .env ]; then
  set -a
  . ./.env
  set +a
fi
paperclip config 2>&1 | grep -E 'Auth:|Health:'
```
