Reusable SKILL.md capabilities that give your agent new expertise — installed into .claude/skills/ and friends.
Research and gather reliable information about libraries, APIs, specifications, and best practices. Use when you need to understand external documentation before planning or implementing a feature.
Use Jujutsu (jj) for version control. Covers workflow, commits, bookmarks, pushing to GitHub, absorb, squash, and stacked PRs. Use when working with jj, creating commits, pushing changes, or managing version control.
# Webcam Capture Use the Logitech C920 webcam to see what's around. ## Basic Capture ```bash IMG=$(~/.claude-mind/system/bin/look) ``` Then use the Read tool to view the captured image at `$IMG`.
Use when user has a selected hypothesis or route and needs a concrete execution plan broken into tasks. Triggered by "what are the next steps", "how do I start", "plan this out".
Run TUnit tests with Playwright. Use when user asks to run tests, execute tests, or check if tests pass.
Set up codebase intelligence for AI agents. Runs the agentifind CLI to extract code structure using LSP (pyright/tsserver) with tree-sitter fallback, then synthesizes a CODEBASE.md navigation guide. Run this skill to get a complete codebase map in .claude/ directory.
Stock chart visualization for Chinese markets with candlestick charts, technical indicators, and multi-chart layouts. Use when needing to visualize stock price patterns, display technical indicators, create comparison charts, or generate analysis reports for A-share stocks.
Use when user has a hypothesis and a repo and wants to run experiments. Triggered by "start experiments", "run the loop", "test this hypothesis".
Database Architect skill. Use this when you need to modify the database schema, add tables, or seed data. This project uses RAW SQL SCRIPTS orchestrated by .NET Aspire, NOT Entity Framework Migrations.
Register webhook endpoints that forward HTTP requests to this chat. Use when user asks to create a webhook, set up an HTTP endpoint, receive API callbacks, integrate external services, listen for incoming requests, or manage existing webhooks (list, delete). Triggers on words like 'webhook', 'endpoint', 'callback', 'HTTP listener', 'API hook', 'incoming request'.
Generate professional git commit message based on changes
Check crypto wallet balances, transaction history, and addresses
Quick code review for files or recent changes, checking for bugs, best practices, and potential improvements
Analyze the current repo structure, build system, test setup, and conventions to provide a practical onboarding guide. Use when new to a codebase, joining a project, or wanting to understand how a repo is organized. Triggers on getting started, new to repo, onboard, how does this repo work, repo structure, codebase overview.
Reference for The Fold's typed comments and doc forms system. Use when adding type annotations, documentation, todos, or other metadata to Scheme code. Covers (doc ...) syntax, standard tags, search commands, and type checker integration.
Implement a GitHub issue by exploring the codebase, planning, and creating a PR
Agent execution engine that composes prompts, routes models, and writes run artifacts. Use when launching subagent runs.
Optimize X/Twitter posts for maximum reach using algorithm insights. Use when writing tweets, improving post engagement, or analyzing why posts underperform.
Fetch web content using curl (faster alternative to WebFetch)
Send files back to the user via Telegram. Use when Claude creates, generates, or modifies a file that the user needs to receive (e.g., generated reports, exported data, created images, code files, archives). Triggers on requests like 'send me the file', 'export as PDF', 'generate a report', 'create a file and send it', or whenever Claude produces a file artifact the user should receive.
