Description
Search and analyze similar historical stock chart patterns and view AI-generated insights on forward returns for informed investing decisions.
README (SKILL.md)
Chart Library
Find historically similar stock chart patterns from 24M+ embeddings across 15K+ symbols and 10 years of data. See what happened next — 1, 3, 5, and 10-day forward returns with AI summaries.
Usage
Ask your agent:
- "Find charts similar to AAPL on 2024-06-15"
- "What are today's most interesting chart patterns?"
- "Analyze TSLA's 3-day chart vs historical analogs"
API Endpoints
POST /api/v1/analyze— Complete analysis in one call (recommended)POST /api/v1/search/text— Search for similar patternsPOST /api/v1/search/batch— Multi-symbol searchGET /api/v1/discover/picks— Today's top patternsPOST /api/v1/follow-through— Forward return computationPOST /api/v1/summary— AI summary generationGET /api/v1/status— Database stats
Auth
No API key required for free tier (100 req/day). For higher limits, get a key at chartlibrary.io/developers.

Usage Guidance
This skill appears coherent and limited to calling chartlibrary.io endpoints. Before installing: verify you trust chartlibrary.io (homepage and OpenAPI links), consider the privacy implications of sending ticker/date queries (these are sent to the external service), and avoid setting a sensitive API key as a widely exported environment variable if you don’t need higher rate limits. If you want to prevent automatic network calls, disable autonomous skill invocation or edit the behavior so searches require explicit user confirmation. If you’ll use the bundled Python wrapper, don't override base_url to an untrusted host (the wrapper allows a base_url parameter), and review the service's privacy/terms if you plan to upload screenshots or proprietary data.
Capability Analysis
Type: OpenClaw Skill
Name: chart-library
Version: 1.0.0
The chart-library skill is a legitimate financial analysis tool designed to find historical stock chart patterns. The Python wrapper (wrapper.py) is a standard HTTP client for the chartlibrary.io API, and the agent instructions (SKILL.md, SOUL.md) appropriately guide the AI to provide data-driven responses while explicitly avoiding financial advice. No evidence of data exfiltration, malicious execution, or prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description match the provided API endpoints and the bundled Python wrapper. The optional CHART_LIBRARY_API_KEY and endpoints are appropriate for a cloud chart-search service; no unrelated credentials or binaries are requested.
Instruction Scope
SKILL.md and SOUL.md instruct the agent to call the Chart Library API for searches, follow-through, summaries, and to run searches when a user mentions a ticker/date (including image uploads). These instructions stick to the service's domain and do not ask the agent to read local files or unrelated environment variables. Note: the guidance to 'immediately search' on mention means the agent may make network calls autonomously when invoked.
Install Mechanism
No install/script downloads are present — the skill is instruction-only with a thin HTTP client (wrapper.py) included. Nothing is extracted or written to disk by an installer.
Credentials
Only an optional CHART_LIBRARY_API_KEY is referenced (wrapper.py reads CHART_LIBRARY_API_KEY). No other secrets, system config paths, or unrelated environment variables are requested.
Persistence & Privilege
The skill is not always-enabled and does not request elevated privileges or modify other skills or system settings. It can be invoked autonomously (platform default), which aligns with the SOUL.md behavior guidance.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install chart-library - After installation, invoke the skill by name or use
/chart-library - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.0
