Zoolanding Lambda Workflow
Use this skill for work in the image-upload Lambda.
Repo Focus
- This service supports both presigned uploads and direct image uploads with server-side optimization.
- The S3 key and returned public URL are contract-sensitive because the frontend stores them in payloads.
- Dependency changes are deployment-sensitive because Pillow must be packaged correctly.
Workflow
-
Read the current contract.
- Start with
README.md, then inspect lambda_function.py, requirements.txt, and template.yaml.
-
Protect upload modes.
- Keep legacy presigned upload behavior stable unless the task explicitly changes it.
- Treat
imageBase64 direct uploads, compression metadata, and content-type normalization as contract-sensitive.
-
Keep image handling practical.
- Prefer clear validation and bounded transforms over clever image heuristics.
- Preserve the current behavior for animated or non-optimizable formats unless asked otherwise.
-
Verify both behavior and packaging assumptions.
- Test the affected request shape for presign or direct upload behavior.
- When dependencies change, build before deploy so packaged artifacts include Pillow.
-
Update docs with the code.
- If request fields, returned metadata, or deployment steps change, update
README.md in the same diff.
Recommended Repo-Local Skills
- Pair this workflow with the repo-local
karpathy-guidelines skill for scoped implementation, systematic-debugging for root-cause analysis, risk-review for review-only asks, and test-driven-development for behavior-changing code.
- Use the repo-local
zoolanding-pr-followup skill for CI, reviewer, and merge-readiness work.
- For shared workspace customization audits or consolidated cross-repo summaries, use the community prompts Workspace AI Customization Audit and Workspace Change Summary.
- Use the repo-local
zoolanding-production-readiness agent for deploy-gate review and the repo-local zoolanding-config-platform-audit agent when a change may require coordinated updates in the frontend or sibling services.
- Use the repo-local
sam-deploy-check prompt before shipping contract or SAM changes.
