+# Sprint 4 - Plugin Commands Implementation
+
+## Metadata
+- **Implementation:** [Change V5.2.0: Plugin Enhancements (Sprint 4 Commands)](https://gitea.hotserv.cloud/personal-projects/leo-claude-mktplace/wiki/Change-V5.2.0%3A-Plugin-Enhancements-%28Sprint-4-Commands%29)
+- **Issues:** #241-#258 (18 issues)
+- **Sprint:** Sprint 4
+- **Completion:** 2026-01-28
+
+## Context
+Implemented 18 new user-facing commands across 8 plugins as part of V5.2.0 Plugin Enhancements. This was a "Commands" sprint focused on expanding plugin functionality.
+
+## What Went Well
+
+### Parallel Agent Execution
+- Ran 7 implementation agents simultaneously without conflicts
+- Each agent focused on a specific plugin's commands
+- Total implementation completed efficiently with parallel work
+
+### Comprehensive Command Coverage
+- Added commands across all major plugin categories
+- Each command follows consistent structure (YAML frontmatter, usage, MCP tools, examples)
+- README updates included with each implementation
+
+### viz-platform MCP Enhancements
+- Added accessibility_tools.py with WCAG color contrast validation
+- Color blind simulation for deuteranopia, protanopia, tritanopia
+- 21 new unit tests for accessibility features
+- Added kaleido dependency for chart export
+
+## Problems Encountered
+
+### Gitea Auto-Close Only Works on Default Branch
+PRs merged to `development` branch don't auto-close issues - the "Closes #XXX" syntax only works when merging to the default branch (main).
+
+**Solution:** Manually closed all 17 remaining issues via MCP `update_issue` tool.
+
+**Prevention:** When creating PRs to non-default branches, plan for manual issue closure or merge to main.
+
+### MCP Project Directory Detection
+The MCP server couldn't detect the user's project directory because `CLAUDE_PROJECT_DIR` wasn't set by Claude Code.
+
+**Solution:** Modified all 5 MCP server `run.sh` scripts to capture PWD before changing directories:
+```bash
+export CLAUDE_PROJECT_DIR="${CLAUDE_PROJECT_DIR:-$PWD}"
+```
+
+**Prevention:** This is now the standard pattern for all MCP server run.sh files.
+
+### .env Format for GITEA_REPO
+The MCP server expects `GITEA_REPO=owner/repo` format, but some projects had separate `GITEA_ORG` and `GITEA_REPO` variables.
+
+**Solution:** Combined into single `GITEA_REPO=personal-projects/leo-claude-mktplace` format.
+
+**Prevention:** Document required .env format clearly in setup commands.
