second-brain-skills

Heptabase CLI Skills gives skills-compatible agents a structured way to manage notes, journals, tags, cards, files, whiteboards, goals, courses, and lessons through the Heptabase command line. The package can be installed for Claude Code, Codex CLI, OpenCode, or other implementations of the Agent Skills specification. It is a skill layer for an existing CLI rather than a standalone Heptabase client, and should be refreshed when the CLI interface or declared compatibility range changes.

tootoo-skills currently contains two focused Claude Code skills. github-kb helps clone repositories, search GitHub, and inspect source code, while skill-router asks interactive questions to identify the right skill for a task. Each directory can be copied independently into the Claude skills folder, or both can be installed together before restarting Claude Code.

obsidian-second-brain turns an Obsidian vault into a shared working memory for Claude Code, Codex, Gemini CLI, OpenCode, Hermes, and Pi. Its commands can save conversations, ingest URLs or files, update related notes, synthesize themes, reconcile contradictions, and search the vault. Installation is platform-specific and requires pointing the agent to the vault; some research, calendar, and background workflows also depend on external services or capabilities that are not available in every supported runtime.

karpathy-llm-wiki turns incoming sources into durable, cross-linked Markdown pages instead of reprocessing raw documents for every question. Its ingest, query, and lint operations update the wiki, answer from existing pages with citations, and check link or index health. It follows the Agent Skills standard for use across several coding agents.
