+## Summary
+
+Describe what changed and why.
+
+## Branch routing
+
+- [ ] Ordinary work targets `develop` from `feature/*`.
+- [ ] A `main` PR comes only from `release_*` or `hotfix/*`.
+- [ ] Release and hotfix changes will also be merged into `develop`.
+
+## Skill checks
+
+- [ ] Changed `SKILL.md` files have valid YAML frontmatter.
+- [ ] Dependencies and supported versions are documented consistently.
+- [ ] Examples, resources, JSON files, and scripts were validated where applicable.
+- [ ] Security, confirmation, secret-handling, network, and fee implications were reviewed.
+- [ ] README and changelog entries were updated when behavior or the public catalog changed.
+
+## Verification

+# Branching and Release Workflow
+
+This repository follows the java-tron branching model while retaining `main` as the name of the
+stable release branch.
+
+## Key branches
+
+| Branch | Purpose |
+|---|---|
+| `develop` | Default development and integration branch for the next release |
+| `main` | Stable branch containing only released Skills collections |
+| `release_vX.Y.Z` | Release snapshot cut from `develop`, regression-tested, and permanently retained |
+| `feature/*` | Feature, fix, documentation, test, refactor, or CI work cut from `develop` |
+| `hotfix/*` | Urgent fix cut from `main` for an already released version |
+
+Direct pushes to `develop` and `main` are not allowed. Changes enter both branches through reviewed
+pull requests.
+
+## Development flow
+
+1. Synchronize a local `develop` branch with `upstream/develop`.
+2. Create `feature/<short_description>` from `develop`.
+3. Submit the pull request to `develop`.
+4. After review and required checks pass, merge it into `develop`.
+
+Use `feature/*` for every ordinary change. The commit and pull-request type still communicates
+whether the work is a feature, fix, documentation update, refactor, test, build, or CI change.
+
+## Release flow
+
+1. Create `release_vX.Y.Z` from `develop` when the release scope is frozen.
+2. Update the repository and Skill versions, changelog, dependency pins, and release notes there.
+3. Run regression, installation, and agent-behavior tests on the release branch.
+4. Merge release-blocking fixes directly into `release_vX.Y.Z`; do not add unrelated features.
+5. After regression passes, merge `release_vX.Y.Z` into `main` and tag the merge commit `vX.Y.Z`.
+6. Merge `release_vX.Y.Z` back into `develop` so every release fix is preserved.
+7. Permanently retain the release branch as the source snapshot for that release.
+
+## Hotfix flow
+
+1. Create `hotfix/<short_description>` from `main`.
+2. Limit the branch to the released defect and its tests or documentation.
+3. Merge the hotfix into `main` and create the corresponding patch release tag.
+4. Merge the same hotfix into `develop`.
+
+## Pull-request routing
+
+| Target | Allowed source branches |
+|---|---|
+| `develop` | `feature/*`, `release_*`, `hotfix/*` |
+| `main` | `release_*`, `hotfix/*` |
+
+The `release_*` and `hotfix/*` routes back to `develop` are mandatory. A feature branch must never
+target `main` directly.
+
+## Installation channels
+
+Because `develop` is the development branch, public installation instructions must select a stable
+source explicitly:
+
+```bash
+npx skills add https://github.com/BofAI/skills/tree/main
+```
+
+Use the development branch only for intentional pre-release testing:
+
+```bash
+npx skills add https://github.com/BofAI/skills/tree/develop
+```
+
+For reproducible production installation, prefer a formal version tag when one is available:
+
+```bash
+npx skills add https://github.com/BofAI/skills/tree/vX.Y.Z
+```
+
+## Required repository settings
+
+Configure GitHub after the bootstrap pull request lands:
+
+- make `develop` the default branch;
+- protect `develop` and `main` from direct and force pushes;
+- require pull requests, at least one approval, and all required checks;
+- require conversation resolution;
+- restrict deletion of both long-lived branches;
+- allow `main` pull requests only from `release_*` and `hotfix/*` through the branch-policy check.
