NEXUS Log Analyzer

Parse and analyze application logs for patterns

Security Scan

The skill appears to be a thin wrapper that sends logs to a paid external NEXUS service — the payment credential requirement and unknown origin are plausible but deserve caution before installing.

Purpose & Capability

The declared purpose (log parsing/analysis) is consistent with the runtime instructions, which call a remote AI endpoint to perform analysis. However, the skill has no homepage/source and is purely a network-forwarding wrapper rather than a local analyzer; that may surprise users who expect on-device processing.

Instruction Scope

SKILL.md explicitly instructs the agent to POST input to https://ai-service-hub-15.emergent.host and to follow payment flows (x402 / MPP / legacy X-Payment-Proof). It does not request filesystem or shell access, and it warns that inputs are sent to the vendor. This is within the stated purpose but means potentially sensitive logs will be transmitted off-host.

Install Mechanism

No install spec or code is provided (instruction-only), so nothing is written to disk by an installer. This is low installer risk.

Credentials

The skill requires a single environment variable NEXUS_PAYMENT_PROOF (primary credential) for payments. Requiring a persistent payment proof as a mandatory env var is sensitive and not strictly necessary given the documented sandbox option and alternative header-based flows; the skill forces storage of a payment credential without explaining lifecycle, scope, or how to obtain it from a trusted source.

Persistence & Privilege

always is false and the skill does not request elevated privileges or to modify other skills. Autonomous invocation is allowed (default) but not excessive here by itself.

What to consider before installing

This skill forwards your input logs to an external paid service (ai-service-hub-15.emergent.host). Before installing: 1) Confirm you trust the NEXUS host and its privacy/policy (there is no homepage/source provided in the package). 2) Avoid storing long-lived payment proofs in a broad environment variable — prefer per-request headers or scoped secrets, and treat NEXUS_PAYMENT_PROOF like a high-sensitivity secret. 3) Test with the documented sandbox (X-Payment-Proof: sandbox_test) first. 4) If your logs contain sensitive PII or credentials, consider local/offline log analysis tools instead of sending them to a remote service. 5) If you proceed, limit where the credential is stored, monitor payments and rotate credentials, and review network traffic to ensure only the documented endpoint is contacted.

When to use

Use when you need to parse and analyze application logs for patterns.

Steps

Option A: x402 Standard (Recommended)

1. Call the service endpoint without payment headers.
2. Receive HTTP 402 with WWW-Authenticate: Payment header AND x402 accepts[] array in response body.
3. Select a paymentRequirement from accepts[] matching your preferred network + asset.
4. Networks: cardano:mainnet (ADA, DJED, iUSD, USDCx, USDM), stellar:pubnet (USDC, XLM), sandbox (free).
5. Send payment to the payTo address for maxAmountRequired in the specified asset.
6. Stellar fee sponsorship: POST your signed XDR to https://ai-service-hub-15.emergent.host/api/mpp/stellar/sponsor — NEXUS pays gas, you need 0 XLM.
7. Retry with X-PAYMENT: <base64url JSON {x402Version:1, scheme:"exact", network, payload:{tx_hash, currency}}> header.
8. Parse the JSON response and X-PAYMENT-RESPONSE header.

Option B: MPP Standard

1. Call the service endpoint without payment headers.
2. Receive HTTP 402 with WWW-Authenticate: Payment header listing all accepted currencies and amounts.
3. Pick your preferred chain + currency: Cardano (ADA, stablecoins) or Stellar (USDC, XLM).
4. Create payment: Masumi escrow (Cardano) or direct Stellar transfer.
5. Stellar fee sponsorship: POST your signed XDR to https://ai-service-hub-15.emergent.host/api/mpp/stellar/sponsor — NEXUS pays gas, you need 0 XLM.
6. Retry with Authorization: Payment <base64url-credential> header.
7. Parse the JSON response and Payment-Receipt header.

Option C: Legacy Header

1. Send a POST request to the NEXUS API endpoint with your input.
2. Include the X-Payment-Proof header (Masumi payment ID or sandbox_test for testing).
3. Parse the JSON response and return the result.

API Call

Endpoint: https://ai-service-hub-15.emergent.host/api/original-services/log-analyzer Method: POST Headers:

• Content-Type: application/json
• X-PAYMENT: <base64url JSON> (x402 standard — recommended)
• Authorization: Payment <credential> (MPP standard)

External Endpoints

URL	Method	Data Sent
https://ai-service-hub-15.emergent.host/api/original-services/log-analyzer	POST	Input parameters as JSON body

Security & Privacy

• All data is sent to https://ai-service-hub-15.emergent.host over HTTPS/TLS.
• No data is stored permanently; requests are processed and discarded.
• Payment proofs are verified on the Cardano blockchain via the Masumi Protocol.
• No filesystem access or shell execution required.

Model Invocation Note

This skill calls the NEXUS AI service API which uses LLM models (GPT-5.2, Claude Sonnet 4.5, GPT-4o) to process requests. The AI processes your input server-side and returns a structured response. You may opt out by not installing this skill.

Trust Statement

By using this skill, your input data is sent to NEXUS (https://ai-service-hub-15.emergent.host) for AI processing. Payments are non-custodial via the Masumi Protocol on Cardano. Only install if you trust NEXUS as a service provider. Visit https://ai-service-hub-15.emergent.host for full documentation.
