Generated Artifacts and Work Products

When work produces a user-inspectable file, upload true deliverables to the current issue before final disposition. Local filesystem paths are not enough because board users, reviewers, and cloud operators may not have access to the agent workspace.

Use Bash to run the helper bundled with this skill; installed skill files may not retain executable permissions. From an installed paperclip skill directory, the helper lives at scripts/paperclip-upload-artifact.sh:

bash scripts/paperclip-upload-artifact.sh path/to/output.webm \
  --title "Walkthrough render" \
  --summary "Rendered walkthrough for review"

The helper uses PAPERCLIP_API_URL, PAPERCLIP_API_KEY, PAPERCLIP_COMPANY_ID, PAPERCLIP_TASK_ID, and PAPERCLIP_RUN_ID. It uploads the file as an issue attachment, creates an attachment-backed artifact work product by default, and prints issue-safe markdown links for your final comment.

Workspace-Only File References

Use a workspace-only reference only when the file should stay in the project or execution workspace, such as a source file, committed report, generated index, or other file whose value is tied to the checkout. This is not a substitute for uploading a deliverable file that a board user should be able to inspect outside the workspace.

Annotate the work product with metadata.resourceRef:

{
  "type": "document",
  "provider": "workspace",
  "title": "Regression test plan",
  "status": "ready_for_review",
  "reviewState": "needs_board_review",
  "summary": "Markdown plan committed in the execution workspace.",
  "metadata": {
    "resourceRef": {
      "kind": "workspace_file",
      "issueId": "<issue-id>",
      "workspaceKind": "execution_workspace",
      "workspaceId": "<execution-workspace-id>",
      "relativePath": "doc/plans/regression-test-plan.md",
      "line": 1,
      "displayPath": "doc/plans/regression-test-plan.md"
    }
  }
}

workspaceKind is execution_workspace for the current issue checkout or project_workspace for a shared project workspace. line and column are optional positive integers. relativePath must be relative to the selected workspace root; do not use host-local absolute paths in resourceRef.

Create the work product with:

curl -sS -X POST \
  "$PAPERCLIP_API_URL/api/issues/$PAPERCLIP_TASK_ID/work-products" \
  -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
  -H "X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID" \
  -H "Content-Type: application/json" \
  --data-binary @workspace-file-work-product.json

If the helper is unavailable, use the Paperclip API directly:

curl -sS -X POST \
  "$PAPERCLIP_API_URL/api/companies/$PAPERCLIP_COMPANY_ID/issues/$PAPERCLIP_TASK_ID/attachments" \
  -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
  -H "X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID" \
  -F 'file=@"path/to/output.webm";type=video/webm'

Then create a work product when the file is the deliverable. The server canonicalizes attachment-backed artifact metadata from the attachmentId:

curl -sS -X POST \
  "$PAPERCLIP_API_URL/api/issues/$PAPERCLIP_TASK_ID/work-products" \
  -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
  -H "X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID" \
  -H "Content-Type: application/json" \
  --data-binary '{
    "type": "artifact",
    "provider": "paperclip",
    "title": "Walkthrough render",
    "status": "ready_for_review",
    "reviewState": "needs_board_review",
    "isPrimary": true,
    "metadata": { "attachmentId": "<uploaded-attachment-id>" }
  }'

In your final issue comment, link the uploaded attachment or work product and describe what it contains. If the output is workspace-only, name the work product and the relative path that was recorded in metadata.resourceRef. Browse/search is the fallback for recovering a workspace file when the issue chip or link cannot open it; it is not the preferred deliverable path. Do not leave artifact-producing work in_progress with only a local path or a Remaining note.

When the current run was started by an external chat request and the file is part of the response intended for that external conversation, have the upload helper bind that specific file to an explicit response comment:

bash scripts/paperclip-upload-artifact.sh path/to/result.png \
  --title "Requested image" \
  --chat-comment "Here is the requested image."

--chat-comment uses the current run-scoped API directly, so it does not depend on a separately installed CLI version. It first uploads the file and creates the same-run artifact work product, then binds that exact attachment to the comment. Concurrent matching invocations on one host serialize by API, company, task, run, filename, content hash, and media type. On retry, the helper reuses the server's immutable same-run attachment record instead of uploading a second copy. A retry from a different host is still subject to server-side attachment admission and should not be run concurrently.

If the upload connection ends without an HTTP response, the helper records that ambiguous outcome locally. The same command polls briefly for Paperclip's immutable attachment record and otherwise stops instead of blindly creating a duplicate. Retry later. Use --retry-unknown-upload only after establishing that the first upload did not commit; this explicit override accepts the risk of creating a duplicate file.

The binding is durable Paperclip state, but it is not proof of external delivery—or even proof that the current run has an active external-chat origin. For an authorized active chat-origin run, Paperclip keeps this selection internal until it selects the run's final response, then attempts the provider publication. The final assistant response may use different prose from --chat-comment.

Treat the helper's exit status as confirmation that the Paperclip attachment, work product, and requested comment binding were saved. Use neutral final prose such as “I prepared the requested image.” Do not claim the file is shown above, attached, queued, or delivered. If the bind step fails after upload, say that the artifact was saved to the Paperclip task but was not bound to the response comment; never also claim that it appears above or is attached.

Do not infer sharing intent from other files on the task or bind every attachment from a run. Only the file passed with --chat-comment is eligible for external publication; unbound artifacts remain Paperclip-only.

Native runner

When register_deliverable is available, use it for files in the bound local or remote workspace. Supply a workspace-relative contentRef, basename filename, contentType, exact byteSize and SHA-256, title, and a stable idempotencyKey. The tool verifies the file, stores an attachment and artifact work product, and binds it to the response. Generic API tools and a legacy API key are unnecessary.

Wait for the receipt. It includes attachmentId, contentPath, and downloadPath, along with the existing command, revision, entity references, and disposition. Reuse the original key after an ambiguous result. A receipt confirms storage and response binding in Paperclip; it does not confirm delivery to an external chat provider. If registration fails, use the returned error to resolve the failure or explain the limitation; do not describe a workspace path as an uploaded file.
