${ctx.prompts.initial}

Repository root: . (the current working directory)

Branches:
- base branch: ${repo.baseBranch}
- work branch: ${repo.workBranch}

Rules:
- analyze only the cloned repository in the current working directory
- treat . as the repository root for read-only inspection
- use bash only for read-only inspection (e.g. git log, git diff, rg, tree, file listing, read-only http/CLI calls)
- do not modify files
- do not read from or write to any original source repository path outside the process workspace
- publish the plan when done`;
