+# .joggr/.gg/
+
+A structured workflow system for managing development projects through a phased pipeline.
+
+## Workflow Pipeline
+
+```
+/gg-new → /gg-discuss → /gg-research → /gg-plan → /gg-execute → /gg-verify
+```
+
+Each step advances the workflow. `.joggr/.gg/state.json` tracks only the active project. Phase status is tracked in phase file YAML frontmatter.
+
+## Skills
+
+Skills are slash commands that drive the workflow. Each skill manages state transitions, user interaction, and agent orchestration.
+
+| Skill         | Description                                                                                                     |
+| ------------- | --------------------------------------------------------------------------------------------------------------- |
+| `gg-new`      | Scaffold a project from a Linear issue/project or free-text description                                         |
+| `gg-status`   | Read-only tree view of project progress                                                                         |
+| `gg-discuss`  | Interview user to gather requirements (goals, constraints, preferences, edge cases, acceptance criteria)        |
+| `gg-research` | Spawn background agent to explore codebase and web for technical context                                        |
+| `gg-plan`     | Create phase plan with tasks, file targets, acceptance criteria, and dependencies                               |
+| `gg-execute`  | Group tasks into parallel waves and spawn executor agents                                                       |
+| `gg-verify`   | Spawn verifier agent to check acceptance criteria with concrete evidence                                        |
+| `gg-codebase` | Analyze repo and maintain `.joggr/.gg/codebase/` docs (stack, architecture, conventions, testing, integrations) |
+| `gg-help`     | Display all available commands and usage                                                                        |
+
+## Agents
+
+Agents are subagents spawned by skills to do the actual work.
+
+| Agent                 | Interactive?    | Description                                                                                           |
+| --------------------- | --------------- | ----------------------------------------------------------------------------------------------------- |
+| `researcher`          | No (background) | Codebase + web researcher — explores code, maps dependencies, finds existing patterns                 |
+| `planner`             | Yes             | Task decomposer — breaks phases into tasks with file targets and acceptance criteria                  |
+| `executor`            | No (background) | Task implementer — executes one task, validates with typecheck/lint/test                              |
+| `verifier`            | No (background) | Acceptance verifier — checks every criterion with concrete evidence                                   |
+| `codebase-researcher` | No (background) | Codebase analyst — explores repo with Serena MCP tools, writes focused docs to `.joggr/.gg/codebase/` |
+
