Web3 Daily

Web3 public research digest service. Provides daily digest with macro news, KOL sentiment, and real-time market data (BTC/ETH prices, Fear & Greed Index). No...

Security Scan

The skill is internally consistent with its stated purpose (fetching a third‑party Web3 digest via an HTTP API) and does not request unrelated credentials or local access, but it relies on an external backend of uncertain provenance so exercise caution.

Purpose & Capability

Name/description promise (daily Web3 digest, KOL sentiment, BTC/ETH prices) matches the runtime instructions: the SKILL.md explicitly directs the agent to call a third‑party API to retrieve the digest. The network permission and external service (j4y-production.up.railway.app) are consistent with the described capability. No unexplained credentials, binaries, or system paths are requested.

Instruction Scope

The instructions are narrowly scoped: they require a single POST to the stated API with only a language field, parsing the JSON 'digest' field, and returning its contents verbatim. The workflow does not ask the agent to read local files, environment variables, or other system state. The requirement to execute the real API call (do not simulate) is explicit but coherent with the skill's promise.

Install Mechanism

This is instruction‑only (no install spec, no code files to execute). No installers, downloads, or archive extraction are present, which minimizes installation risk.

Credentials

The skill declares no required environment variables or credentials and the claw.json documents that only 'language_preference' is shared with the external service. There are no disproportionate or unrelated secrets requested.

Persistence & Privilege

The skill does not request always:true and does not modify other skills or system settings. Autonomous invocation is allowed by platform default but not combined with high privilege or credential access.

Assessment

This skill is coherent: it simply asks the agent to POST a language flag to a third‑party API and display the returned 'digest'. Before installing, consider that (1) the service endpoint (https://j4y-production.up.railway.app) is a third‑party backend hosted on Railway — the operator could log requests and responses, so avoid sending any private or sensitive content through this skill; (2) the skill's guarantees (no personal data sent) are based on the provided instructions and metadata — you should verify the backend operator (GitHub repo owner) and review the service's privacy practices if you need higher assurance; and (3) the skill enforces returning raw API content, so availability or correctness depends entirely on that external service. If the skill ever requested API keys, local file access, or other credentials, or if the endpoint were an obscure/personal IP/shortened URL, reclassification to 'suspicious' would be warranted.

Workflow A: Full Digest (Default)

⚠️ CRITICAL: You MUST execute the curl command below. DO NOT generate fake/simulated content.

Steps:

1. Tell user: "Fetching latest Web3 digest..."

2. MUST EXECUTE this curl command (do not skip or simulate):

For Chinese output (default):

curl -s -X POST "https://j4y-production.up.railway.app/api/v1/digest/public" \
  -H "Content-Type: application/json" \
  -d '{"language": "zh"}'

For English output:

curl -s -X POST "https://j4y-production.up.railway.app/api/v1/digest/public" \
  -H "Content-Type: application/json" \
  -d '{"language": "en"}'

3. Parse the JSON response and extract the digest field

4. Display the EXACT content from digest field to user (do not modify or summarize)

---

Workflow B: Compact Digest (For Quick Reading / Push)

Trigger: User asks for "简版" / "compact" / "short version" / "quick digest"

Steps:

1. Tell user: "Fetching compact Web3 digest..."

2. MUST EXECUTE this curl command（推荐 /digest/compact；/digest/public/compact 为兼容别名）:

For Chinese output:

curl -s -X POST "https://j4y-production.up.railway.app/api/v1/digest/compact" \
  -H "Content-Type: application/json" \
  -d '{"language": "zh"}'

For English output:

curl -s -X POST "https://j4y-production.up.railway.app/api/v1/digest/compact" \
  -H "Content-Type: application/json" \
  -d '{"language": "en"}'

3. Parse the JSON response and extract the digest field

4. Display the EXACT content from digest field to user

Compact version features:

• ~2500 words (50-60% of full version)
• No URL links (cleaner for messaging apps)
• Keeps core insights: 3 themes, KOL sentiment summary, risks & opportunities
• Table format for quick scanning

  "language": "zh"
}

❌ DO NOT:

• Generate your own digest content
• Summarize or paraphrase the API response
• Skip the API call and make up data
• Return "example" or "simulated" content

✅ MUST:

• Execute the actual curl command
• Return the exact digest content from API response
• Include real BTC/ETH prices and Fear & Greed Index from the response

Language Support

Detect user's language preference:

• If user speaks Chinese → use "language": "zh"
• If user speaks English → use "language": "en"
• If unclear, default to Chinese
