Core skills

These skills come with every TDT workspace; no optional stacks are required. Use them to manage your workspace, knowledge, projects and workflows through your agent. Select a skill below to read its usage guide. In Claude, invoke it with / before its name; in Codex, use $ or the skill picker.

Claude and Codex group automatic discovery under tdt-brain, tdt-reminders, tdt-relay, tdt-stacks, tdt-skills, tdt-workspace and tdt-mcp. You can also invoke the specialist skills below directly. Stack and approved user skills remain individually discoverable.

• tdt-capture — Save explicitly supplied knowledge with sources and related links.

• tdt-note — Save a tagged scratchpad idea and find related notes.

• tdt-search-notes — Recall saved ideas and intentions through note content and subject tags.

• tdt-add-project — Register an existing project without changing its files. Get an explanation of its purpose, structure and entry points.

• tdt-relink-project — Reconnect a renamed or moved project and update its path-based identity and references.

• tdt-remove-project — Archive, restore or permanently unregister a project, with optional reviewed reference cleanup.
