Each agent focused on a specific plugin's commands
Total implementation completed efficiently with parallel work

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:

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.
