+# Project Guidelines
+
+This file documents the branching strategy, commit conventions, and PR policies for the a2a-java project.
+
+- Fix branch naming pattern: `issue-<ISSUE_NUMBER>`
+- Feature branch naming pattern: `issue-<ISSUE_NUMBER>-<short-slug>`
+- Bugfix branch naming pattern: `issue-<ISSUE_NUMBER>`
+- Quick-fix branch naming pattern: `quick-fix/<short-slug>`
+- SonarCloud branch naming pattern: _(n/a — no SonarCloud)_
+- CI-fix branch naming pattern: `ci-issue/<short-slug>`
+- Commit format (fix): Conventional Commits — `<type>(<scope>): <description>\n\nFixes #<ISSUE_NUMBER>`
+- Commit format (quick-fix): `chore: <brief description>`
+- Commit format (ci-fix): `ci: <brief description>`
+- PR creation policy: always
+- Find-task source: GitHub labels
+- Find-task beginner label: `good first issue`
+- Find-task intermediate label: _(none)_
+- Find-task experienced label: `help wanted`
+- Scope-too-large redirect: break into smaller issues and PRs; squash commits into one logical commit per PR unless multiple meaningful commits are warranted
+
+## Notes
+
+- PRs must be reviewed by at least one a2a-java committer before merging.
+- Link the issue in both the PR description and the commit message (e.g. `Fixes #<NUMBER>`).
+- PRs should include tests and documentation for new functionality.
+- Prefer squashing all commits into a single commit for small changes.
