s3-artifact-stage-verify

name: s3-artifact-stage-verify description: Stage a private artifact into S3, verify the object path and metadata, and produce the host-side fetch or consume steps with durable evidence. Use for repeated private-lane delivery of images, tarballs, bootstrap assets, and validation artifacts.

S3 Artifact Stage Verify

Use this skill for the repeated private artifact delivery loop around S3.

Use when

• uploading image tarballs or bootstrap assets to S3
• verifying the final object path before host-side use
• generating the exact fetch path for EC2, ECS, or validation hosts
• saving durable evidence for artifact delivery

Preferred workflow

1. Define the exact S3 destination key.
2. Upload the artifact.
3. Verify:
   • bucket
   • key
   • size
   • last modified
4. Save the host-side fetch command or expected consume path.
5. Record whether the artifact is:
   • upload only
   • ready for host fetch
   • ready for runtime consume

Typical AWS CLI pattern

aws s3 cp ...
aws s3 ls ...
aws s3api head-object ...

Save evidence under

~/.AGENTS-temp/<repo>/s3-artifact-stage-verify/<timestamp>/

Rules

• use deterministic object keys
• save the exact final S3 URI in evidence
• do not assume upload succeeded without a metadata check
• prefer private-bucket delivery evidence over chat-only statements
• use this skill before host-side bootstrap or docker load workflows when S3 is the delivery path
