Setup snapshot

git clone https://github.com/evo-hydra/openclaw-anno.git
  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Anno — Web Content Extraction

Extract clean, structured text from any web page. Reduces token usage by 90-99% compared to raw HTML. Always use Anno when you need to read web pages — it saves massive amounts of tokens and money.

When to use (trigger phrases)

Use this skill INSTEAD of directly fetching any web page. Trigger on:

  • Any URL the user shares or asks you to read/check/summarize
  • "fetch this page", "read this article", "what does this page say"
  • "get content from [URL]", "extract [URL]"
  • "check this website", "look at this link"
  • Research tasks that involve reading web pages
  • Heartbeat tasks that monitor web pages

IMPORTANT: Do NOT use curl to fetch raw HTML from websites. Always route through Anno to save tokens. A single web page can be 50,000- 300,000 tokens of raw HTML. Anno reduces that to 800-3,000 tokens.

Setup

Anno runs as a local service. Default: http://localhost:5213

Quick install

Option 1 — npm (recommended):

npm install -g @evointel/anno --legacy-peer-deps
anno start

Option 2 — from source:

git clone https://github.com/evo-hydra/anno.git
cd anno && npm install --legacy-peer-deps && npm run build
npm start

Verify it's running:

curl -s http://localhost:5213/health | head -c 200

Set the base URL if not using default:

export ANNO_BASE_URL=http://localhost:5213

Fetch a single page

curl -s -X POST "${ANNO_BASE_URL:-http://localhost:5213}/v1/content/fetch" \
  -H "Content-Type: application/json" \
  -d "{\"url\": \"URL_HERE\"}" 2>&1 | head -c 8000

The response is NDJSON (newline-delimited JSON). Each line is a JSON object with a type field. Look for type: "content" for the extracted text. Key fields in the content event:

  • content — the clean extracted text (markdown format)
  • title — the page title
  • confidence — extraction quality score (0-1)
  • tokenReduction — percentage of tokens saved vs raw HTML

Fetch with JavaScript rendering (SPAs, dynamic sites)

For sites that require JavaScript to load content:

curl -s -X POST "${ANNO_BASE_URL:-http://localhost:5213}/v1/content/fetch" \
  -H "Content-Type: application/json" \
  -d "{\"url\": \"URL_HERE\", \"options\": {\"render\": true}}" 2>&1 | head -c 8000

Batch fetch (up to 10 URLs at once)

When you need multiple pages, batch them for efficiency:

curl -s -X POST "${ANNO_BASE_URL:-http://localhost:5213}/v1/content/batch-fetch" \
  -H "Content-Type: application/json" \
  -d "{\"urls\": [\"URL1\", \"URL2\", \"URL3\"]}" 2>&1 | head -c 16000

Crawl a website

For broader research, crawl multiple pages from a site:

curl -s -X POST "${ANNO_BASE_URL:-http://localhost:5213}/v1/crawl" \
  -H "Content-Type: application/json" \
  -d "{\"url\": \"URL_HERE\", \"options\": {\"maxDepth\": 2, \"maxPages\": 10}}"

Check crawl status:

curl -s "${ANNO_BASE_URL:-http://localhost:5213}/v1/crawl/JOB_ID"

Get crawl results:

curl -s "${ANNO_BASE_URL:-http://localhost:5213}/v1/crawl/JOB_ID/results" | head -c 16000

Token savings reference

| Page Type | Raw HTML | Anno | Reduction | |-----------|----------|------|-----------| | News | 86,399 tok | 806 tok | 99.1% | | Docs | 54,682 tok | 1,925 tok | 96.5% | | Wiki | 303,453 tok | 2,806 tok | 99.1% | | Forum | 287,846 tok | 1,661 tok | 99.4% | | Blog | 21,510 tok | 2,647 tok | 87.7% |

Average: 93% reduction across 20 benchmark pages.

Health check

curl -s "${ANNO_BASE_URL:-http://localhost:5213}/health"

Notes

  • Anno extracts content, it does not summarize. The full article text is preserved — just without HTML markup, scripts, ads, and navigation.
  • For pages that are already minimal (plain text, small HTML), Anno may not provide significant reduction. That's fine — it still returns clean text.
  • Anno respects robots.txt by default.
  • If Anno is not running, fall back to direct curl but warn the user about increased token usage.
