Missing skill for uploading pre-built PNG files to S3

[krishagel]

Summary

No available skill supports uploading a pre-built PNG/PDF file directly to S3. The agent was asked to upload a pre-built PNG infographic (not agent-generated) but could not find a sanctioned tool: psd-html-artifact/deliver.js only accepts .html files (hard extension check), and psd-image-gen/generate.js only uploads images it generates itself from a prompt. Per Rule 9, the agent did not write custom S3 upload code and instead offered to wrap the PNG in a minimal HTML page as the closest sanctioned alternative.

Definition of Done

• Root cause identified: confirm no existing skill supports arbitrary PNG/PDF upload to S3
• Proposed solution documented (e.g., extend psd-html-artifact to accept PNG/PDF, or create a new psd-file-upload skill)
• (manual) Solution implemented and verified

Error details

error_class: tool_unavailable
error_message: "User asked to upload a pre-built PNG infographic (not agent-generated via psd-image-gen, not an .html artifact) directly to S3 with a shareable link. No available skill supports uploading an arbitrary pre-existing PNG/PDF file: psd-html-artifact/deliver.js only accepts .html files (hard extension check), and psd-image-gen/generate.js only uploads images it generates itself from a prompt (or edits via --image as a reference input to OpenAI, not a passthrough upload). Per Rule 9 I did not write custom S3 upload code to work around this. Offered to wrap the PNG in a minimal HTML page and deliver that via psd-html-artifact as the closest sanctioned alternative."
context: {"tool": null, "user_facing": true, "self_reported": true}

Acceptance tests / E2E flows

N/A — this is a feature gap, not a code bug.

Affected areas

• psd-html-artifact/deliver.js (hard .html extension check)
• psd-image-gen/generate.js (only uploads self-generated images)
• S3 upload tooling

Out of scope

• Writing custom S3 upload code as a workaround
• Changing the agent self-reporting behavior

Risk & rollback

• Risk: low — new feature/skill addition
• Rollback: remove the new skill or revert the extension
