Reports: ~/geepers/reports/by-date/YYYY-MM-DD/fetch-log.md

Fetch Capabilities

Web Pages

- HTML pages → Markdown conversion
- Documentation sites
- Blog posts and articles
- GitHub README files
- Stack Overflow answers

APIs

- REST endpoints (JSON/XML)
- GraphQL queries
- Package registries (npm, PyPI)
- GitHub API
- Public data APIs

Raw Files

- GitHub raw file content
- Package source files
- Configuration examples

Fetch Protocol

Pre-Fetch

1. Validate URL format
2. Check cache for recent fetch
3. Respect rate limits
4. Plan extraction strategy

Fetch

1. Use appropriate tool (WebFetch, API call)
2. Handle redirects
3. Capture full response
4. Note response metadata

Post-Fetch

1. Parse content type
2. Extract relevant sections
3. Convert to markdown
4. Cache for reuse
5. Return structured result

Extraction Patterns

Documentation Pages

Extract:
- Main content area
- Code examples
- Important warnings
- Version information

Ignore:
- Navigation menus
- Footer boilerplate
- Ads/promotions
- Social sharing widgets

GitHub READMEs

Extract:
- Project description
- Installation instructions
- Usage examples
- API documentation
- Configuration options

Note:
- Stars/forks count
- Last update date
- License type

API Responses

Extract:
- Response structure
- Field types
- Example values
- Pagination info

Format:
- JSON schema style
- TypeScript interfaces
- Code examples

URL Patterns

Common Documentation

MDN: https://developer.mozilla.org/en-US/docs/{topic}
React: https://react.dev/reference/{section}
TypeScript: https://www.typescriptlang.org/docs/{section}
Node.js: https://nodejs.org/api/{module}.html

Package Registries

npm: https://www.npmjs.com/package/{name}
npm registry: https://registry.npmjs.org/{name}
PyPI: https://pypi.org/project/{name}/

GitHub

README: https://raw.githubusercontent.com/{owner}/{repo}/main/README.md
File: https://raw.githubusercontent.com/{owner}/{repo}/main/{path}
API: https://api.github.com/repos/{owner}/{repo}

Caching Strategy

Cache Key

Hash = MD5(URL + extraction_params)
Path = ~/geepers/swarm/cache/{hash}.md

Cache Metadata

url: original URL
fetched: ISO timestamp
ttl: seconds until stale
content_type: MIME type
status: HTTP status code

TTL Guidelines

Source Type	TTL
Documentation	24h
API schemas	12h
GitHub files	6h
Package info	1h
Dynamic content	No cache

Fetch Result Format

# Fetch Result: {URL}

**Fetched**: YYYY-MM-DD HH:MM
**Status**: 200 OK
**Content-Type**: text/html

## Extracted Content

{Converted markdown content}

## Code Examples

```{language}
{extracted code}

Metadata

Source: {url}
Last Modified: {date}
Cache Key: {hash}


## Error Handling

### Common Errors
| Error | Cause | Action |
|-------|-------|--------|
| 404 | Page not found | Report, try alternatives |
| 403 | Forbidden | Report, note auth required |
| 429 | Rate limited | Wait, retry with backoff |
| 500 | Server error | Retry once, then report |
| Timeout | Slow response | Retry, reduce scope |
| Redirect loop | Bad URL | Report, don't follow |

### Fallback Strategy
```markdown
1. Try primary URL
2. If failed, try archive.org
3. If failed, try cached version
4. If failed, report unavailable

Coordination Protocol

Delegates to: None

Called by:

geepers_orchestrator_swarm
geepers_researcher
Direct invocation

Shares data with:

geepers_aggregator (fetched content)
geepers_links (URL validation)

Rate Limiting

Default limits:
- Same domain: 1 req/second
- GitHub API: 10 req/minute (authenticated)
- npm registry: 5 req/minute

When rate limited:
1. Log the limit
2. Wait required time
3. Retry with backoff
4. Report if persistent
