# Wikipedia AI Skills

A curated collection of skill files for AI coding agents - [Pi](https://github.com/earendil-works/pi), [OpenCode](https://opencode.ai), [Claude Code](https://docs.anthropic.com/en/docs/claude-code), and any agent that supports the `.claude/<name>/SKILL.md` convention - to help with Wikipedia, Wikimedia, and Wikidata-related tasks.

Whether you're editing a Wikipedia article, researching a topic, or building a Toolforge tool, these skills give your AI assistant expert guidance on Wikimedia's systems, policies, and data.

Each skill is a self-contained set of instructions, policy knowledge, code examples, and executable tooling that an agent loads on demand. This means agents get expert-level guidance without bloating their system prompt.

## Why skills matter: measured impact

These skills are not just reference docs — they measurably improve AI agent performance on Wikimedia tasks. In controlled benchmarks comparing agents with and without skills loaded:

- **2.8× average speedup** — agents with skills completed tasks faster (2.2× for simple tasks → 3.1× for complex cross-domain tasks)
- **50% silent failure rate → 0%** — without skills, agents produced plausible-looking but wrong answers in half of all tasks. With skills, this dropped to zero.
- **The gap widens with complexity** — the most complex, cross-domain tasks showed the largest advantage. Skills help most where the agent needs to navigate multiple Wikimedia systems (API + policy + wikitext + Wikidata) in a single task.

In short: skills make agents **faster, cheaper (fewer tokens wasted on wrong paths), and dramatically more reliable.**

## ⚠️ Important: AI-generated content on Wikimedia projects

**Most language editions of Wikipedia and other Wikimedia projects have community policies that restrict or ban the direct posting of content generated by large language models (LLMs).** This includes articles, sections, discussion comments, or any other substantial prose drafted by AI assistants, as well as images and other media files, whether uploaded to Wikimedia Commons or directly to a single Wikipedia edition. Before using AI to generate content, you **must** consult all relevant AI policies. These are summarised on Meta-Wiki at [AI policies by project](https://meta.wikimedia.org/wiki/Artificial_intelligence/Policies_by_project). You must read the full policies and guidelines, not just the summaries.

These skills are designed to **help you research, understand, and prepare content** - not to produce final text for direct submission. If you use the biography-writing skill to draft an article, treat the output as a **research aid and starting point**, not a finished product. Any Wikipedia edit you make remains your own responsibility and must comply with Wikipedia's policies on verifiability, neutral point of view, and no original research.

**Do not copy-paste AI-generated text directly into Wikipedia.** Always rewrite, verify every claim against reliable sources, and ensure the result reflects your own editorial judgment.

cp -r Wikipedia-AI-Skills/.claude/skills/wikimedia-pageviews /path/to/your/project/.claude/skills/
```

Once installed, your AI coding agent will discover the skill automatically through the `skill` tool. You can also open any `SKILL.md` file and paste its contents directly into an agent's instructions.

### Pi agent setup

[Pi](https://github.com/earendil-works/pi) discovers skills from anywhere on the filesystem via `settings.json`.

#### Step 1: Clone the repo

```bash
mkdir -p ~/.pi/repos
git clone https://github.com/fuzheado/Wikipedia-AI-Skills.git ~/.pi/repos/Wikipedia-AI-Skills
```

#### Step 2: Add skills and extension to pi's settings

Edit `~/.pi/agent/settings.json`:

```json
{
  "skills": [
    "~/.pi/repos/Wikipedia-AI-Skills/.claude/skills"
  ],
  "extensions": [
    "~/.pi/repos/Wikipedia-AI-Skills/.pi/extensions/wikimedia-skills"
  ]
}
```

#### Step 3: Set your own contact info in the User-Agent (required)

The extension ships with a placeholder User-Agent. **You must replace the contact information with your own** — Wikimedia uses this to reach you if your requests cause issues.

Choose one of these methods:

> **Option A (recommended) — Persistent config that survives `git pull`**

Copy the template to your home config directory, then edit the copy:

```bash
# 1. Create the user config directory
mkdir -p ~/.config/wikimedia-skills

# 2. Copy the template (this is a one-time copy)
cp ~/.pi/repos/Wikipedia-AI-Skills/.pi/extensions/wikimedia-skills/config.json \
   ~/.config/wikimedia-skills/config.json

# 3. Open the copy and replace the userAgent value with your own info
$EDITOR ~/.config/wikimedia-skills/config.json
```

In that file, change the `"userAgent"` value to your own contact info. The format is:

```
<client>/<version> (<contact URL or email>) <project>
```

For example:

```json
{
  "userAgent": "MyBot/1.0 (https://github.com/yourname; yourname@example.com) SkillsDemo"
}
```

> **Option B — Quick override (lasts one shell session)**

```bash
export WIKIMEDIA_USER_AGENT="MyBot/1.0 (https://github.com/yourname; yourname@example.com) SkillsDemo"
```

#### Step 4: Reload pi

```bash
/reload
```

After reloading, the **User-Agent injection extension** is active: every `curl`, `wget`, `python`, and `node` command targeting a Wikimedia server automatically gets a compliant User-Agent — no 403 errors, no manual intervention needed.

#### How the User-Agent is resolved

The extension checks these locations in order (first match wins):

1. `WIKIMEDIA_USER_AGENT` environment variable
2. `~/.config/wikimedia-skills/config.json` (your personal config — survives `git pull`)
3. The repo's `.pi/extensions/wikimedia-skills/config.json` (shipped default — do not edit, `git pull` overwrites it)

> ⚠️ **Do not edit the repo's `config.json` directly.** It is a template and `git pull` will overwrite your changes. Always use `~/.config/wikimedia-skills/config.json` or the `WIKIMEDIA_USER_AGENT` environment variable.

## Script compliance

All shell and Python scripts in this repository follow a **script compliance standard**
defined in [`.claude/guidelines/script-audit-guidelines.md`](.claude/guidelines/script-audit-guidelines.md):

- ✅ **Zero-argument guard** — every script prints a helpful usage message when invoked with no arguments
- ✅ **Portable bash** — no bash 4+ features (`declare -A`, `${var,,}`) that break on macOS's default bash 3.2
- ✅ **Safe piped output** — `curl | python3` patterns use temp files with HTTP status checks instead of silently passing empty/invalid input
- ✅ **`--help` support** — every script responds to `--help` with full documentation
- ✅ **Deferred imports** — Python scripts with optional dependencies show help before crashing on missing imports

See the [full guidelines](.claude/guidelines/script-audit-guidelines.md) for the pre-commit hook, CI workflow templates, and checklist for new scripts.

## Ground-truth verification suite

Skills document many CLI commands, API calls, URLs, and code snippets. To guard
against **hallucinated content** — plausible-looking commands/modules/URLs that
do not exist (e.g. `toolforge tools create`, `action=templatestyles`,
`prop=translationinfo`) — this repo keeps ground-truth registries captured from
live systems, and every skill is verified against them in CI
(`.github/workflows/skill-verification.yml`):

| Check | Registry (generated) | Refresher |
|---|---|---|
| CLI commands (`toolforge`, `pwb.py`, `webservice`, `sql`, `become`) | `scripts/command-registry.json` | `scripts/refresh-command-registry.py` (SSH to bastion + pywikibot repo) |
| Action API modules (`action=`/`prop=`/`list=`/`meta=`) | `scripts/api-surface.json` | `scripts/refresh-api-surface.py` (live paraminfo, enwiki+wikidata+commons) |
| External URLs (status checked) | `scripts/url-registry.json` | `scripts/refresh-url-registry.py` (incremental HEAD sweep, freshness rotation) |
| Links/`depends_on`/wikilinks | — (offline) | `scripts/verify-links.py` |
| Code snippet syntax (python/bash/json/js) | — (offline) | `scripts/verify-snippets.py` |
| `last_verified` freshness | — (offline) | `scripts/verify-freshness.py` |

Run all checks locally:

```bash
python3 scripts/verify-commands.py
python3 scripts/verify-api.py
python3 scripts/verify-links.py
python3 scripts/verify-snippets.py
python3 scripts/verify-freshness.py
```

Refresh the registries when the underlying systems change (or every few months):

```bash
TOOLFORGE_USER=<your-ldap-username> python3 scripts/refresh-command-registry.py
python3 scripts/refresh-api-surface.py
python3 scripts/refresh-url-registry.py   # incremental: new + stale (>90d) + broken (>30d)
python3 scripts/refresh-url-registry.py --new-only  # fast pre-push check after adding URLs
python3 scripts/refresh-url-registry.py --full      # rare full audit of every URL
```
URL refresh is incremental by default: a URL is only live-checked if it is new, outside the
~3-month freshness window (`--max-age-days`), or a known-broken URL due for a retry
(`--retry-after-days`). Known-good URLs are skipped, so normal runs check only the handful
that rotated in — no more multi-minute sweeps on every change. CI's `verify-links.py` is fully
offline; a scheduled workflow (`.github/workflows/url-registry-refresh.yml`, weekly) keeps the
registry fresh automatically.

Prose that *documents* removed commands ("the `toolforge tools...` family was
removed"), error demos, illustrative placeholder URLs, and POST-only endpoints
is automatically recognized and skipped.

## Testing

New contributions should include tests. The project uses `pytest` with a test suite in
`tests/` covering:

- **YAML frontmatter validation** - every SKILL.md must have valid `name`, `description`,
  `license`, and `compatibility` fields
- **Content accuracy** - key SOP claims, code examples, and guardrails are verified
  against the actual markdown
- **Code execution** - runnable Python assets (like the cross-API pipeline script and the
  Pywikibot quick reference) have mock-based unit tests

## Research & Validation

The skills in this repository were validated through a systematic A/B test — **24 parallel agent runs across 12 tasks in 3 rounds of escalating complexity** — comparing agent performance with and without skill injection.

**Key findings:**
- **2.8× average speedup** with skills loaded (2.2× for simple tasks → 3.1× for complex cross-domain tasks)
- **50% silent failure rate without skills** vs. **0% with skills** — the no-skills agents produced plausible-looking wrong answers in half of all tasks
- The gap widens with task complexity: the most complex tasks showed the largest advantage

See **[`research/ab-testing/`](research/ab-testing/)** for the full reports, including:
- Round-by-round results (R1: simple APIs, R2: multi-step workflows, R3: cross-domain orchestration)
- Meta-analysis synthesizing all 12 comparisons
- Skills improvement recommendations derived from test findings
- Code example consistency audit

```bash
pip install pytest pyyaml requests
python -m pytest tests/
```

## Skill format

Every skill lives in `.claude/skills/<name>/` with this structure:

```
my-skill/
├── SKILL.md              # Agent-facing instructions with SOPs
├── scripts/              # Executable helpers (bash, python, etc.)
├── references/           # Deep reference docs loaded on-demand
└── assets/               # Templates, config files, sample data
```

The `SKILL.md` file includes YAML frontmatter for agent discovery:

```yaml
---
name: skill-name
description: Short description for agent discovery
license: MIT
compatibility: opencode
---
## SOP: ...
...agent-facing instructions...
```

## Design context

For background on the design motivations and community tools that inspired this project, see
**[PAWS, Quarry, and the Wikimedia AI Facility](https://docs.google.com/presentation/d/1KWzhtDk4LnpwT-FCSYSMa4moOWcx9OZ2RF9i_REQOfI/edit?usp=sharing)**
— a presentation covering the origins of [PAWS](https://wikitech.wikimedia.org/wiki/PAWS) (hosted Jupyter notebooks
for Wikimedia) and [Quarry](https://quarry.wmcloud.org/) (public SQL query interface for wiki databases), and what they
suggest about designing an AI-assisted editing facility for the Wikimedia community.

## Contributing

See [CONTRIBUTING.md](CONTRIBUTING.md) for detailed guidelines on adding new skills, improving existing ones, and the pull request process. All skills must follow the YAML frontmatter format and pass the content accuracy checklist.
