Blocklet URL Analyzer

Analyze URLs in the Blocklet Server ecosystem, identify request types, and locate corresponding development repositories.

Core Philosophy

"Bridge from URL to code."

When issues occur in production, developers only have a URL in hand. This skill serves as the bridge: analyzing URL type (Daemon/Service/Blocklet), locating the specific repository and code path, making the "URL → code" path clear and traceable.

Use Cases

  • User provides a Blocklet Server related URL and wants to know which repository to develop in
  • During debugging, need to know which component a URL corresponds to
  • Reverse lookup development repository from production environment URL

Critical Rule

⚠️ NEVER use Chrome browser or any interactive browser tools to analyze URLs.

ALWAYS use terminal commands (curl, wget, etc.) to make HTTP requests directly.

This is a strict requirement - all URL analysis must be done via command line, not browser automation.

Repository Reference Files

This skill includes local reference files for repository lookup:

  • references/org-arcblock-repos.md - ArcBlock organization repos (core infrastructure, SDKs, mobile apps)
  • references/org-blocklet-repos.md - Blocklet organization repos (blocklet applications, kits, tools)
  • references/org-aigne-repos.md - AIGNE organization repos (AI agent framework, LLM adapters)

Active Loading Policy (ALP)

Load reference files on-demand based on context. Do not preload all files.

Trigger Condition Load File
Need ArcBlock core repos (blocklet-server, ux, did-connect, SDKs) references/org-arcblock-repos.md
Need Blocklet app repos (payment-kit, media-kit, discuss-kit, etc.) references/org-blocklet-repos.md
Need AIGNE AI repos (aigne-framework, aigne-hub, LLM adapters) references/org-aigne-repos.md
Uncertain which organization First read references/README.md for high-density summary

Loading Strategy:

  1. First determine which organization the repository likely belongs to based on blocklet name/context
  2. Load only the relevant reference file
  3. If uncertain, read references/README.md first to decide which file to load
  4. Prefer local reference files over gh commands for repository lookup

URL Type Classification

1. Blocklet Server Daemon (Core Management Interface)

Characteristics:

  • Main domain (not IP DNS domain)
  • Path starts with /admin

Examples:

https://node-dev-1.arcblock.io/admin/blocklets
https://node-dev-1.arcblock.io/admin/blocklets/zNKWm5HBgaTLptTZBzjHo6PPFAp8X3n8pabY/components
https://example.com/admin/settings

Corresponding repository: ArcBlock/blocklet-server


2. Blocklet Service (Blocklet Built-in Service Interface)

Characteristics:

  • IP DNS domain (format: {did}-{ip}.ip.abtnet.io)
  • Path starts with /.well-known/service/admin

Examples:

https://bbqaqc2vvt4mte2n4mta7dlgpsoxakc2gejo3wrrx34-18-180-145-193.ip.abtnet.io/.well-known/service/admin/overview
https://bbqaqc2vvt4mte2n4mta7dlgpsoxakc2gejo3wrrx34-18-180-145-193.ip.abtnet.io/.well-known/service/admin/operations

Corresponding repository: ArcBlock/blocklet-server (service module)


3. Specific Blocklet (Third-party Blocklet Applications)

Characteristics:

  • IP DNS domain
  • Path starts with blocklet's mount path (not /.well-known)
  • Or IP DNS domain root path

Examples:

https://bbqaqc2vvt4mte2n4mta7dlgpsoxakc2gejo3wrrx34-18-180-145-193.ip.abtnet.io/image-bin/admin/images
https://bbqaqc2vvt4mte2n4mta7dlgpsoxakc2gejo3wrrx34-18-180-145-193.ip.abtnet.io/payment-kit/admin
https://bbqaqc2vvt4mte2n4mta7dlgpsoxakc2gejo3wrrx34-18-180-145-193.ip.abtnet.io

Corresponding repository: Need to request URL to analyze which specific blocklet


Workflow

Phase 1: URL Parsing

// Parse URL to get key information
const url = new URL(inputUrl);
const host = url.hostname;
const path = url.pathname;

Phase 2: Domain Type Detection

2.1 Detect Domain Type

// IP DNS domain regex
const IP_DNS_PATTERN = /^[a-z0-9]+-(\d{1,3}-){3}\d{1,3}\.ip\.abtnet\.io$/;
const DID_DNS_PATTERN = /^[a-z0-9]+\.did\.abtnet\.io$/;

const isIpDnsDomain = IP_DNS_PATTERN.test(host) || DID_DNS_PATTERN.test(host);
const isArcBlockDomain = host.endsWith('.arcblock.io') || host.endsWith('.abtnet.io');
Domain Type Detection Result
*.ip.abtnet.io IP DNS domain → Possibly Blocklet
*.did.abtnet.io DID DNS domain → Possibly Blocklet
*.arcblock.io / *.abtnet.io ArcBlock domain → Check path and request API
Other domains Regular domain → Check path, may also be Blocklet

Phase 3: Path Type Detection

const DAEMON_ADMIN_PATH = '/admin';
const WELLKNOWN_SERVICE_PATH = '/.well-known/service';
const WELLKNOWN_PATH = '/.well-known';

3.1 Detection Flow

IF not IP DNS domain AND path.startsWith('/admin')
  → Type: DAEMON
  → Repository: ArcBlock/blocklet-server

ELSE IF IP DNS domain AND path.startsWith('/.well-known/service/admin')
  → Type: BLOCKLET_SERVICE
  → Repository: ArcBlock/blocklet-server

ELSE IF IP DNS domain AND (path === '/' OR !path.startsWith('/.well-known'))
  → Type: BLOCKLET
  → Need further identification of specific blocklet

ELSE IF path.startsWith('/.well-known') AND !path.startsWith('/.well-known/service')
  → Type: WELLKNOWN
  → Repository: ArcBlock/blocklet-server

ELSE IF isArcBlockDomain OR otherDomain
  → Type: POSSIBLE_BLOCKLET
  → Try to request API to identify (proceed to Phase 4)

ELSE
  → Type: UNKNOWN
  → Need user to provide more information

Important: For non-IP DNS domains (like spaces.staging.arcblock.io), always try to request the Blocklet API first before marking as UNKNOWN. Many Blocklets run on regular domains.

Phase 4: Blocklet Identification (BLOCKLET or POSSIBLE_BLOCKLET Type)

When URL type is BLOCKLET or POSSIBLE_BLOCKLET, need to request API to get specific blocklet information.

4.1 Extract Mount Path

// Extract mount path (first path segment) from path
const pathParts = path.split('/').filter(Boolean);
const mountPath = pathParts.length > 0 ? `/${pathParts[0]}` : '/';

4.2 Request Blocklet Information

Method A: Request blocklet.js (Recommended)

This is the most reliable method. The __blocklet__.js?type=json endpoint returns information about the main blocklet AND all its components.

# Get full blocklet metadata (returns JSON when type=json)
BLOCKLET_DATA=$(curl -sS "${ORIGIN}/__blocklet__.js?type=json" 2>/dev/null)

# Extract main blocklet info
echo "$BLOCKLET_DATA" | jq '{appName, appId, appUrl}'

# Extract component mount points
echo "$BLOCKLET_DATA" | jq '.componentMountPoints'

Important: The appName and appId fields are for the main blocklet (the service). To find the specific component for a mount path, you need to search in componentMountPoints:

# Find component by mount path
# Example: For URL https://team.arcblock.io/task/..., MOUNT_PATH="/task"
COMPONENT=$(echo "$BLOCKLET_DATA" | jq --arg mp "$MOUNT_PATH" '.componentMountPoints[] | select(.mountPoint == $mp)')
echo "$COMPONENT" | jq '{name, did, title, mountPoint}'

Component fields:

  • name: Component name (may be the DID itself for some blocklets)
  • did: Component DID (use this to identify the blocklet)
  • title: Human-readable title (e.g., "FlowBoard", "Payment Kit")
  • mountPoint: The URL path where this component is mounted

Special case - root path: If mount path is /, find the component with mountPoint: "/":

ROOT_COMPONENT=$(echo "$BLOCKLET_DATA" | jq '.componentMountPoints[] | select(.mountPoint == "/")')

Method B: Request Page to Analyze Meta Tags

# Request page to get HTML
curl -sS "$URL" | grep -oP '(?<=<meta name="blocklet-did" content=")[^"]*'

Method C: Legacy DID API (may not work for all setups)

# Construct API URL
API_URL="${ORIGIN}/.well-known/service/api/did/blocklet"
curl -sS "$API_URL" | jq '.name, .did, .title'

4.3 Blocklet to Repository Mapping

Step 1: Domain-based quick identification

Some Blocklets can be identified by their domain pattern:

Domain Pattern Repository Name
spaces*.arcblock.io did-spaces
store.blocklet.dev blocklet-store

Step 2: Query local reference files (following ALP)

Based on the blocklet name, determine which organization it likely belongs to:

  • Core infrastructure (blocklet-server, ux, did-connect, SDKs) → Load references/org-arcblock-repos.md
  • Blocklet apps (payment-kit, media-kit, discuss-kit, etc.) → Load references/org-blocklet-repos.md
  • AI-related (aigne-*, LLM adapters) → Load references/org-aigne-repos.md
  • Uncertain → First read references/README.md for high-density summary

Reference file format:

| Name | URL | Main Branch | Branch Prefix | Description | Category |

Search by blocklet name or keyword in the loaded file.

Common blocklet name/title to repository name mapping:

Blocklet Name/Title (from API) Repository Name (in references)
image-bin / Media Kit media-kit
did-spaces / DID Spaces did-spaces
payment-kit / Payment Kit payment-kit
did-comments / Discuss Kit discuss-kit
FlowBoard flow-board
pages-kit / Pages Kit pages-kit
vote / Vote vote
ai-studio / AIGNE Studio ai-studio
meilisearch / Search Kit meilisearch-kit
excalidraw / Excalidraw excalidraw
virtual-gift-card / Virtual Gift Card virtual-gift-card
nft-blender / NFT Blender nft-blender

Note: The name field from componentMountPoints may be a DID string (e.g., z2qa4xMVAJxvA1GgfnPpMFqhdSjU9pe37NCiY) when the blocklet uses its DID as the internal name. In such cases, use the title field for human-readable identification and search in reference files.

Step 3: If no match found

Use AskUserQuestion to let user confirm repository

Integration with dev-setup Skills

When blocklet-dev-setup or blocklet-server-dev-setup receives a URL that is not a GitHub Issue, call this skill to analyze:

  1. Analyze URL type
  2. Identify corresponding repository
  3. Return repository info to dev-setup skill to continue execution

Output Protocol

After analysis completes, output structured data for caller to parse:

<<<BLOCKLET_URL_ANALYSIS>>>
{
  "type": "DAEMON | BLOCKLET_SERVICE | BLOCKLET | WELLKNOWN | UNKNOWN",
  "url": "original URL",
  "host": "domain",
  "path": "path",
  "repo": "org/repo-name",
  "repoType": "blocklet-server | blocklet",
  "blocklet": {
    "name": "blocklet name (if BLOCKLET type)",
    "did": "blocklet DID",
    "title": "blocklet title",
    "mountPath": "mount path"
  }
}
<<<END_BLOCKLET_URL_ANALYSIS>>>
