Description
Fact-check news articles, social media posts, images, and videos. Use when verifying claims, detecting deepfakes or AI-generated content, identifying out-of-...
Usage Guidance
This instruction-only skill appears internally consistent with a fact‑checking purpose. It will fetch and analyze user-provided URLs, images, and videos (and may download media to /tmp briefly). No environment variables are required, but you can optionally provide API keys (Google Fact Check, Brave Search, OpenAI) to enable extra features. Before installing, consider: (1) ensure you are comfortable allowing the skill to perform web searches and download user-supplied media for analysis, (2) optional tools (ffmpeg, exiftool, c2patool, whisper) increase analysis depth but are not required, and (3) if you lack a configured web search, the skill will not perform text verification until you set one up (it suggests Brave Search).
Capability Analysis
Type: OpenClaw Skill
Name: openclaw-fact-checker
Version: 1.0.1
The skill is a comprehensive multimodal fact-checking tool designed to verify text, images, and videos using web search, vision capabilities, and standard CLI utilities like ffmpeg and exiftool. While it executes shell commands and suggests a configuration update to AGENTS.md for persistence, these actions are transparently aligned with its stated purpose and follow standard OpenClaw patterns. No evidence of malicious intent, data exfiltration, or unauthorized remote control was found across the pipeline files (text_pipeline.md, image_pipeline.md, video_pipeline.md).
Capability Assessment
Purpose & Capability
Name/description (multimodal fact checking) aligns with the instructions and references: text/image/video pipelines, reverse image search, EXIF/C2PA checks, ffmpeg/whisper usage, and optional Google/Brave/OpenAI APIs. No unrelated secrets or binaries are required.
Instruction Scope
SKILL.md gives detailed, narrowly scoped runtime steps that stay within fact‑checking (web searches, WebFetch, reverse image search, metadata extraction, ffmpeg keyframe extraction, transcription). It requires access to arbitrary URLs and user‑provided media (expected), writes temporary files under /tmp, and conditionally calls optional CLI tools. Note: the text pipeline mandates having web search available and explicitly refuses to proceed without it for text verification — this is an operational dependency rather than a security incoherence.
Install Mechanism
Instruction-only skill with no install spec and no downloaded code. Optional tooling is invoked only if present on PATH; recommended install commands are typical package manager invocations. No external arbitrary archive downloads or custom install scripts are present.
Credentials
No required environment variables or credentials. Optional env vars are appropriate and proportionate to functionality (GOOGLE_FACTCHECK_API_KEY for the Fact Check API, BRAVE_SEARCH_API_KEY for web search, OPENAI_API_KEY for Whisper API). No unrelated secrets or multiple unrelated credentials requested.
Persistence & Privilege
Skill is not forced‑always, does not request elevated or cross‑skill configuration changes, and has default autonomous-invocation settings. It does not ask to persist credentials or modify other skills.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install openclaw-fact-checker - After installation, invoke the skill by name or use
/openclaw-fact-checker - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.1
- Updated environment variable and binary dependencies to "optional" rather than "required".
- Added new optional binaries: whisper.
- Added new optional environment variables: OPENAI_API_KEY and BRAVE_SEARCH_API_KEY.
- Clarified setup instructions and dependency handling.
- No changes detected to core logic or execution pipelines.
v1.0.0
New skill version adds multimodal (text, image, video) fact-checking, multilingual support, and structured pipelines:
- Supports fact-checking news articles, social posts, images, and videos, including deepfake/AI detection.
- Introduces distinct pipelines for text, image, and video inputs, with language and modality auto-detection.
- Enforces report language to match user input, with clear label translation rules.
- Adds detailed confidence scoring, mandatory source citation, and strict objective/anti-hallucination guidelines.
- Removes previous script-based pipeline; now uses structured reference files for all modalities.
- Requires only specific CLI tools (ffmpeg, exiftool, c2patool) and disables external package dependencies.
