+# Requirements for a check (copied from checks/write.md)
+
+If you'd like to add a check, make sure it meets the following criteria and then
+create a new GitHub Issue to discuss with the team:
+
+1. The scorecard must only be composed of automate-able, objective data. For
+    example, a project having 10 contributors doesn’t necessarily mean it’s more
+    secure than a project with 50 contributors. But, having two maintainers
+    might be preferable to only having one - the larger bus factor and ability
+    to provide code reviews is objectively better.
+2. The scorecard criteria can be as specific as possible and are not limited to
+    general recommendations. For example, for Go, we can recommend/require
+    specific linters and analyzers to be run on the codebase.
+3. The scorecard can be populated for any open source project without any work
+    or interaction from maintainers.
+4. Maintainers must be provided with a mechanism to correct any automated
+    scorecard findings they feel were made in error, provide "hints" for
+    anything we can't detect automatically, and even dispute the applicability
+    of a given scorecard finding for that repository.
+5. Any criteria in the scorecard must be actionable. It should be possible,
+    with help, for any project to "check all the boxes".
+ Any solution to compile a scorecard should be usable by the greater open
+    source community to monitor upstream security.

+## Check Brainstorm
+
+## SBOM Check description
+
+- General: Establish framework to check for sbom related items, beginning with existence of published sbom in any form, leveraging the exiting and emerging standards for locations and naming. Also with the ability to add additional functionality later as sboms become more adopted.
+- Probes:
+  - Check for published SBOM (MVP)
+  - Verify SBOM format (spdx, cyclonedx) (MVP?)
+  - Check for SBOM quality (leveraging sbom-scorecard) (#2605)
+
+## Probe Breakdown - Check for published SBOM
+
+- Standards to leverage:
+  - security insights 1.0.0 spec:
+    - <https://github.com/ossf/security-insights-spec/blob/v1.0.0/specification.md#dependencies>
+  - sbom-everywhere naming and directory conventions
+    - <https://github.com/ossf/sbom-everywhere/blob/main/reference/sbom_naming.md>
+- places to check:
+  - Gitlab/hub release artifacts
+  - pipeline/workflow artifacts
+  - security insights 1.0.0 spec:
+    - Location specified in SECURITY_INSßIGHTS.yml (dependency#sbom section)
+  - sbom-everywhere naming and directory conventions:
