docs(website): dedicated page per bundled + optional skill (#14929)
Generates a full dedicated Docusaurus page for every one of the 132 skills
(73 bundled + 59 optional) under website/docs/user-guide/skills/{bundled,optional}/<category>/.
Each page carries the skill's description, metadata (version, author, license,
dependencies, platform gating, tags, related skills cross-linked to their own
pages), and the complete SKILL.md body that Hermes loads at runtime.
Previously the two catalog pages just listed skills with a one-line blurb and
no way to see what the skill actually did — users had to go read the source
repo. Now every skill has a browsable, searchable, cross-linked reference in
the docs.
- website/scripts/generate-skill-docs.py — generator that reads skills/ and
optional-skills/, writes per-skill pages, regenerates both catalog indexes,
and rewrites the Skills section of sidebars.ts. Handles MDX escaping
(outside fenced code blocks: curly braces, unsafe HTML-ish tags) and
rewrites relative references/*.md links to point at the GitHub source.
- website/docs/reference/skills-catalog.md — regenerated; each row links to
the new dedicated page.
- website/docs/reference/optional-skills-catalog.md — same.
- website/sidebars.ts — Skills section now has Bundled / Optional subtrees
with one nested category per skill folder.
- .github/workflows/{docs-site-checks,deploy-site}.yml — run the generator
before docusaurus build so CI stays in sync with the source SKILL.md files.
Build verified locally with `npx docusaurus build`. Only remaining warnings
are pre-existing broken link/anchor issues in unrelated pages.

# Duckduckgo Search
|
||||
|
||||
Free web search via DuckDuckGo — text, news, images, videos. No API key needed. Prefer the `ddgs` CLI when installed; use the Python DDGS library only after verifying that `ddgs` is available in the current runtime.

# DuckDuckGo Search
|
||||
|
||||
Free web search using DuckDuckGo. **No API key required.**
|
||||
|
||||
Preferred when `web_search` is unavailable or unsuitable (for example when `FIRECRAWL_API_KEY` is not set). Can also be used as a standalone search path when DuckDuckGo results are specifically desired.
|
||||
|
||||
## Detection Flow
|
||||
|
||||
Check what is actually available before choosing an approach:
|
||||
|
||||
```bash
|
||||
# Check CLI availability
|
||||
command -v ddgs >/dev/null && echo "DDGS_CLI=installed" || echo "DDGS_CLI=missing"
|
||||
```
|
||||
|
||||
Decision tree:
|
||||
1. If `ddgs` CLI is installed, prefer `terminal` + `ddgs`
|
||||
2. If `ddgs` CLI is missing, do not assume `execute_code` can import `ddgs`
|
||||
3. If the user wants DuckDuckGo specifically, install `ddgs` first in the relevant environment
|
||||
4. Otherwise fall back to built-in web/browser tools
|
||||
|
||||
Important runtime note:
|
||||
- Terminal and `execute_code` are separate runtimes
|
||||
- A successful shell install does not guarantee `execute_code` can import `ddgs`
|
||||
- Never assume third-party Python packages are preinstalled inside `execute_code`
|
||||
|
||||
## Installation
|
||||
|
||||
Install `ddgs` only when DuckDuckGo search is specifically needed and the runtime does not already provide it.
|
||||
|
||||
```bash
|
||||
# Python package + CLI entrypoint
|
||||
pip install ddgs
|
||||
|
||||
# Verify CLI
|
||||
ddgs --help
|
||||
```
|
||||
|
||||
If a workflow depends on Python imports, verify that same runtime can import `ddgs` before using `from ddgs import DDGS`.
|
||||
|
||||
## Method 1: CLI Search (Preferred)
|
||||
|
||||
Use the `ddgs` command via `terminal` when it exists. This is the preferred path because it avoids assuming the `execute_code` sandbox has the `ddgs` Python package installed.
|
||||
|
||||
```bash
|
||||
# Text search
|
||||
ddgs text -q "python async programming" -m 5
|
||||
|
||||
# News search
|
||||
ddgs news -q "artificial intelligence" -m 5
|
||||
|
||||
# Image search
|
||||
ddgs images -q "landscape photography" -m 10
|
||||
|
||||
# Video search
|
||||
ddgs videos -q "python tutorial" -m 5
|
||||
|
||||
# With region filter
|
||||
ddgs text -q "best restaurants" -m 5 -r us-en
|
||||
|
||||
# Recent results only (d=day, w=week, m=month, y=year)
|
||||
ddgs text -q "latest AI news" -m 5 -t w
|
||||
|
||||
# JSON output for parsing
|
||||
ddgs text -q "fastapi tutorial" -m 5 -o json
|
||||
```
|
||||
|
||||
### CLI Flags
|
||||
|
||||
| Flag | Description | Example |
|
||||
|------|-------------|---------|
|
||||
| `-q` | Query — **required** | `-q "search terms"` |
|
||||
| `-m` | Max results | `-m 5` |
|
||||
| `-r` | Region | `-r us-en` |
|
||||
| `-t` | Time limit | `-t w` (week) |
|
||||
| `-s` | Safe search | `-s off` |
|
||||
| `-o` | Output format | `-o json` |
|
||||
|
||||
## Method 2: Python API (Only After Verification)
|
||||
|
||||
Use the `DDGS` class in `execute_code` or another Python runtime only after verifying that `ddgs` is installed there. Do not assume `execute_code` includes third-party packages by default.
|
||||
|
||||
Safe wording:
|
||||
- "Use `execute_code` with `ddgs` after installing or verifying the package if needed"
|
||||
|
||||
Avoid saying:
|
||||
- "`execute_code` includes `ddgs`"
|
||||
- "DuckDuckGo search works by default in `execute_code`"
|
||||
|
||||
**Important:** `max_results` must always be passed as a **keyword argument** — positional usage raises an error on all methods.
|
||||
|
||||
### Text Search
|
||||
|
||||
Best for: general research, companies, documentation.
|
||||
|
||||
```python
|
||||
from ddgs import DDGS
|
||||
|
||||
with DDGS() as ddgs:
|
||||
for r in ddgs.text("python async programming", max_results=5):
|
||||
print(r["title"])
|
||||
print(r["href"])
|
||||
print(r.get("body", "")[:200])
|
||||
print()
|
||||
```
|
||||
|
||||
Returns: `title`, `href`, `body`
|
||||
|
||||
### News Search
|
||||
|
||||
Best for: current events, breaking news, latest updates.
|
||||
|
||||
```python
|
||||
from ddgs import DDGS
|
||||
|
||||
with DDGS() as ddgs:
|
||||
for r in ddgs.news("AI regulation 2026", max_results=5):
|
||||
print(r["date"], "-", r["title"])
|
||||
print(r.get("source", ""), "|", r["url"])
|
||||
print(r.get("body", "")[:200])
|
||||
print()
|
||||
```
|
||||
|
||||
Returns: `date`, `title`, `body`, `url`, `image`, `source`
|
||||
|
||||
### Image Search
|
||||
|
||||
Best for: visual references, product images, diagrams.
|
||||
|
||||
```python
|
||||
from ddgs import DDGS
|
||||
|
||||
with DDGS() as ddgs:
|
||||
for r in ddgs.images("semiconductor chip", max_results=5):
|
||||
print(r["title"])
|
||||
print(r["image"])
|
||||
print(r.get("thumbnail", ""))
|
||||
print(r.get("source", ""))
|
||||
print()
|
||||
```
|
||||
|
||||
Returns: `title`, `image`, `thumbnail`, `url`, `height`, `width`, `source`
|
||||
|
||||
### Video Search
|
||||
|
||||
Best for: tutorials, demos, explainers.
|
||||
|
||||
```python
|
||||
from ddgs import DDGS
|
||||
|
||||
with DDGS() as ddgs:
|
||||
for r in ddgs.videos("FastAPI tutorial", max_results=5):
|
||||
print(r["title"])
|
||||
print(r.get("content", ""))
|
||||
print(r.get("duration", ""))
|
||||
print(r.get("provider", ""))
|
||||
print(r.get("published", ""))
|
||||
print()
|
||||
```
|
||||
|
||||
Returns: `title`, `content`, `description`, `duration`, `provider`, `published`, `statistics`, `uploader`
|
||||
|
||||
### Quick Reference
|
||||
|
||||
| Method | Use When | Key Fields |
|
||||
|--------|----------|------------|
|
||||
| `text()` | General research, companies | title, href, body |
|
||||
| `news()` | Current events, updates | date, title, source, body, url |
|
||||
| `images()` | Visuals, diagrams | title, image, thumbnail, url |
|
||||
| `videos()` | Tutorials, demos | title, content, duration, provider |
|
||||
|
||||
## Workflow: Search then Extract
|
||||
|
||||
DuckDuckGo returns titles, URLs, and snippets — not full page content. To get full page content, search first and then extract the most relevant URL with `web_extract`, browser tools, or curl.
|
||||
|
||||
CLI example:
|
||||
|
||||
```bash
|
||||
ddgs text -q "fastapi deployment guide" -m 3 -o json
|
||||
```
|
||||
|
||||
Python example, only after verifying `ddgs` is installed in that runtime:
|
||||
|
||||
```python
|
||||
from ddgs import DDGS
|
||||
|
||||
with DDGS() as ddgs:
|
||||
results = list(ddgs.text("fastapi deployment guide", max_results=3))
|
||||
for r in results:
|
||||
print(r["title"], "->", r["href"])
|
||||
```
|
||||
|
||||
Then extract the best URL with `web_extract` or another content-retrieval tool.
|
||||
|
||||
## Limitations
|
||||
|
||||
- **Rate limiting**: DuckDuckGo may throttle after many rapid requests. Add a short delay between searches if needed.
|
||||
- **No content extraction**: `ddgs` returns snippets, not full page content. Use `web_extract`, browser tools, or curl for the full article/page.
|
||||
- **Results quality**: Generally good but less configurable than Firecrawl's search.
|
||||
- **Availability**: DuckDuckGo may block requests from some cloud IPs. If searches return empty, try different keywords or wait a few seconds.
|
||||
- **Field variability**: Return fields may vary between results or `ddgs` versions. Use `.get()` for optional fields to avoid `KeyError`.
|
||||
- **Separate runtimes**: A successful `ddgs` install in terminal does not automatically mean `execute_code` can import it.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
| Problem | Likely Cause | What To Do |
|
||||
|---------|--------------|------------|
|
||||
| `ddgs: command not found` | CLI not installed in the shell environment | Install `ddgs`, or use built-in web/browser tools instead |
|
||||
| `ModuleNotFoundError: No module named 'ddgs'` | Python runtime does not have the package installed | Do not use Python DDGS there until that runtime is prepared |
|
||||
| Search returns nothing | Temporary rate limiting or poor query | Wait a few seconds, retry, or adjust the query |
|
||||
| CLI works but `execute_code` import fails | Terminal and `execute_code` are different runtimes | Keep using CLI, or separately prepare the Python runtime |
|
||||
|
||||
## Pitfalls
|
||||
|
||||
- **`max_results` is keyword-only**: `ddgs.text("query", 5)` raises an error. Use `ddgs.text("query", max_results=5)`.
|
||||
- **Do not assume the CLI exists**: Check `command -v ddgs` before using it.
|
||||
- **Do not assume `execute_code` can import `ddgs`**: `from ddgs import DDGS` may fail with `ModuleNotFoundError` unless that runtime was prepared separately.
|
||||
- **Package name**: The package is `ddgs` (previously `duckduckgo-search`). Install with `pip install ddgs`.
|
||||
- **Don't confuse `-q` and `-m`** (CLI): `-q` is for the query, `-m` is for max results count.
|
||||
- **Empty results**: If `ddgs` returns nothing, it may be rate-limited. Wait a few seconds and retry.
|
||||
|
||||
## Validated With
|
||||
|
||||
Validated examples against `ddgs==9.11.2` semantics. Skill guidance now treats CLI availability and Python import availability as separate concerns so the documented workflow matches actual runtime behavior.
