Usage Guidance
This appears to be a coherent Veritier fact-checking integration. Before installing or running examples: 1) Only provide a vt_ API key to the veritier.ai endpoint and keep test keys (vt_test_...) separate from production keys. 2) If you run the Python/JS examples, install dependencies in an isolated environment (venv/container) and review the code yourself; the examples make outbound calls to api.veritier.ai. 3) Be cautious with logs and CI — test_integration.py prints the first 12 characters of the key (local console output), so avoid running it in shared logs with production keys. 4) If you plan to accept webhooks, protect your VERITIER_WEBHOOK_SECRET and deploy the receiver over HTTPS as suggested. 5) Only install the skill if you trust veritier.ai for handling your verification requests; you can revoke API keys from the dashboard at any time.
Capability Analysis
Type: OpenClaw Skill
Name: veritier-fact-checking
Version: 2.1.2
The Veritier fact-checking skill bundle is a well-documented and legitimate integration for an AI-powered verification service. The code, including the Python MCP proxy (veritier_mcp_proxy.py) and various JavaScript/Python examples, follows security best practices by hardcoding the API destination (https://api.veritier.ai) to prevent credential exfiltration and using timing-safe HMAC-SHA256 verification for webhooks (webhook_receiver.py). The instructions in SKILL.md are appropriately scoped to user onboarding and error handling, and the inclusion of a dedicated 'test mode' using 'vt_test_' keys demonstrates a focus on safe developer integration without malicious intent.
Capability Tags
Capability Assessment
Purpose & Capability
The name/description (fact-checking/claim extraction) aligns with the files and instructions: all examples call https://api.veritier.ai endpoints, provide extract/verify tools, and the only required credential is VERITIER_API_KEY. There are no unrelated credentials (e.g., cloud provider keys) or unexpected binaries required.
Instruction Scope
SKILL.md and the example scripts limit activity to extracting/verifying claims and (optionally) receiving signed webhooks. Instructions do not ask the agent to read unrelated system files or other environment variables beyond the declared ones; network destinations are hardcoded to api.veritier.ai. Webhook examples expect a local receiver and an HMAC secret (optional).
Install Mechanism
There is no registry install spec (instruction-only skill), which is low-risk. The repository includes example code (Python/JS) that requires installing common libs (httpx, mcp, anyio, flask, npm deps). If you run those examples, you'll install dependencies locally; the package sources referenced are typical and traceable (PyPI / npm).
Credentials
The only required environment variable is VERITIER_API_KEY (declared as primaryEnv). Optional env vars (VERITIER_TEST_KEY, VERITIER_WEBHOOK_SECRET) are documented and used only for testing/webhook signature verification. No unrelated secrets or broad system paths are requested.
Persistence & Privilege
The skill is not always-enabled and does not request system-wide configuration changes. It exposes MCP integration and local proxy examples, but does not modify other skills or agent configs autonomously in the provided materials.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install veritier-fact-checking - After installation, invoke the skill by name or use
/veritier-fact-checking - Provide required inputs per the skill's parameter spec and get structured output
Version History
v2.1.2
- Added support for two optional environment variables: VERITIER_TEST_KEY (test key, never used in production) and VERITIER_WEBHOOK_SECRET (webhook payload signing).
- Updated metadata to describe these optional environment variables and clarify their usage and security.
- No functional or API changes.
v2.1.1
- Added enhanced security metadata, specifying that the VERITIER_API_KEY is only sent as a Bearer token to https://api.veritier.ai and never to any other domain.
- Documented network destinations as hardcoded for improved transparency and compliance.
- No changes to functional logic or APIs.
v2.1.0
- Included full core implementation examples in Python and JavaScript.
- Enablement of test sandbox for integration validation with no quota consumption.
v2.0.0
**Major update: Adds claim extraction tools, reference-based verification, and flexible input size limits.**
- New tools: `extract_text`, `extract_document`, and `verify_document` for claim extraction and document-based verification.
- Support for verifying claims against user-provided private references (not just web sources).
- Input size limit increased to 32,000 characters for text extraction and verification.
- Free tier now includes 100 extractions/month in addition to 25 verifications.
- API usage/quotas and onboarding instructions updated for new tools and workflows.
v1.0.4
- Added Openclaw metadata block with environment variable details.
- Removed the legacy "auth" block and streamlined API key instructions.
- Updated MCP CLI setup example from "claude mcp" to "mcp add".
- No code or API/model changes; documentation and metadata only.
v1.0.2
- Added explicit credentials metadata specifying required and optional environment variables for API key configuration.
- No functional or documentation changes apart from minor metadata enrichment for credential handling.
v1.0.1
- Added structured authentication block to SKILL.md, detailing API key usage and configuration.
- Updated onboarding instructions: users now add the API key locally in their MCP config/environment, keeping it private and only sending it to api.veritier.ai.
- Clarified language throughout for improved setup and security guidance.
- Removed "hallucination detection" and some implementation notes from the skill description to focus on core fact-checking.
- No code or interface changes; documentation improvements only.
v1.0.0
Initial release of the Veritier fact-checking skill.
- Real-time fact-checking and claim verification from any text.
- Extracts falsifiable claims, checks each against live web evidence, and returns structured verdicts with confidence scores and source URLs.
- Connect via MCP or REST API - no local installation required.
- Includes onboarding guidance for first-time users and upgrade instructions when free limits are reached.
- Supports Free, Pro, and Business plans with clear usage limits and error messaging.
