+# Software Development Practices for ROOST Projects
+
+Good software development lifecycle (SDLC) is an endless journey, but it's hard to make progress if you don't know where you're going. This document is intended to be a checklist for ROOST projects to work through as they mature.
+
+_**Document status:** Working draft. Suggested categories, checks, and priority below._
+
+## Quality vision
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Intention statement | Sets the ethos for what kind of software we're building and for who. | P0 |
+## Versioning
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Versioning| ROOST projects are using semantic versioning | P1 |
+| Branching | Are there different branches for stable and development? | P0 |
+## Release cadence
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Initial Process | * Identify big features on 12 month timeline. These are _substantial_ changes (think blog headline).
* Estimate delivery time in quarters of big features and group features with similar timelines together. Bundle breaking changes when possible.
* Add minor features/changes to timeline. Bundle together for as consistent cadence as possible.
* Patch versions can be cut at any time as needed for bug fixes. | P0 |
+## Testing practices
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Tests for all commits | 1) Unit tests
2) Lint checks
3) Integration tests
4) Build checks | P0 |
+| Release tests | End-to-end testing for Major and Minor releases | P0 |
+## Dependency handling
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Version alerts | Automated alerts and process for updating dependencies | P0|
+| Vulnerability alerts | Automated alerts and process for updating dependencies | P0|
+| License scanning | Ensuring compatible licenses for dependencies added via CI | P1 |
+| Vendoring policy | Do we ever vendor deps? | P2 |
+## Security in CI/CD
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Fuzzing | At what milestones? | P2 |
+| Code analysis | CodeQL, secret and token scanning, etc | P1 |
+| Binary artifact detection | Flagging checked in binaries | P2 |
+| Commit-time vuln detection | Flags for packages with known CVEs | P2 |
+## Release security
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Signed releases | | P3 |
+| Security report intake | See .github/security.md | P0 |
+| Incident response process | See OpenSSF process | P1 |
+## PR triage and code review
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Issue labeling | How can this be automated or less burdensome? | P2 |
+| PR labeling| How can this be automated or less burdensome, and identify priority? | P2 |
+| Code review guidance | What should reviewers pay attention to? | P1 |
+## Support
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Breaking changes policy | Following semver, breaking changes go in Major versions. This policy is about when it's appropriate to introduce a breaking change and how it should be communicated to users (timeline, expectations, support) | P1 |
+| Long term support (LTS) policy | How many versions back does the community support? | P3 -- address later |
+## Deprecation
+| Item | Description/Notes | Priority |
+| ------- | --------- | -------- |
+| Deprecation process | | P3 -- address when needed |

-| Branching | Are there different branches for stable and development? | P0 |
+| Branching | To start, ROOST projects should use `main` as the branch for development, and use the GitHub Release feature (via semver-tagged commits) to denote releases. This will need to be revisited as projects mature and have to handle backporting patches, but the ethos is "minimum viable complexity." | P0 |

+## Project conventions
+| Item | Description/Notes | Priority |
+| ----- | ---------------- | --------- |
+| README.md | All projects/repos must have a README file in markdown format. At minimum, the README must have a description of what the project does, information for how to start using it (can link to longer getting started documentation), and links to the CONTRIBUTING.md and Code of Conduct. | P0 |
+| AGENTS.md | Add a markdown file to guide AI coding assistants following the open [AGENTS.md format](https://github.com/agentsmd/agents.md) | P1 |
+| API format | Projects should follow the [TBD] API description format | P1 |
+| CHANGELOG.md | Projects must have a CHANGELOG.md file, following the [Keep A Changelog format](https://keepachangelog.com/en/1.1.0/) | P0 |
+| Contributor guidance | All projects must have a CONTRIBUTING.md file at minimum. By default this is inherited from ROOST's .github, but can be updated at the per-project level. Additional documentation for first time contributors describing project conventions and code quality expectations is recommended. | P0 |
+| CODE_OF_CONDUCT.md | All projects must have a CODE_OF_CONDUCT.md with the ROOST Code of Conduct. This is automatically inherited from ROOST's .github and should not be changed. | P0 |
