 When you are creating a plan file in the repository itself, new plan documents belong in `doc/plans/` and should use `YYYY-MM-DD-slug.md` filenames.

+# Agent Artifact Upload Workflow
+
+Generated files that a board user or reviewer should inspect must be attached to
+the Paperclip issue before the agent chooses a final disposition. A local
+workspace path is not enough, because cloud users and reviewers often cannot
+access the agent's disk.
+
+Use the helper from the repo root:
+
+```sh
+scripts/paperclip-upload-artifact.sh path/to/output.webm \
+  --title "Walkthrough render" \
+  --summary "Rendered walkthrough for review"
+```
+
+The helper uses the authenticated Paperclip API from the current heartbeat
+environment:
+
+- `PAPERCLIP_API_URL`
+- `PAPERCLIP_API_KEY`
+- `PAPERCLIP_COMPANY_ID`
+- `PAPERCLIP_TASK_ID`
+- `PAPERCLIP_RUN_ID`
+
+It uploads the file to
+`POST /api/companies/{companyId}/issues/{issueId}/attachments` and creates an
+artifact work product on `POST /api/issues/{issueId}/work-products` by default.
+The command prints issue-safe markdown links for the final task comment.
+
+## Completion Pattern
+
+When a task produces a user-inspectable file:
+
+1. Generate and verify the file locally.
+2. Upload it with `scripts/paperclip-upload-artifact.sh`.
+3. Keep the artifact work product unless the file is incidental; pass
+   `--no-work-product` only for supporting files that should not be promoted.
+4. Link the printed attachment URL in the final issue comment.
+5. Then set the final issue status.
+
+Final comments should name the uploaded artifact, not just the local filesystem
+path. Local paths can be included as diagnostic context, but they cannot be the
+only access path.
+
+## Video Examples
+
+Upload an `.mp4` render:
+
+```sh
+scripts/paperclip-upload-artifact.sh dist/demo.mp4 \
+  --title "Demo video render" \
+  --summary "MP4 render for board review"
+```
+
+Upload a `.webm` render:
+
+```sh
+scripts/paperclip-upload-artifact.sh out/walkthrough.webm \
+  --title "Walkthrough video" \
+  --summary "WebM walkthrough render"
+```
+
+The helper detects `.mp4`, `.webm`, and `.mov` content types. If a renderer uses
+an unusual extension, pass the MIME type explicitly:
+
+```sh
+scripts/paperclip-upload-artifact.sh render.bin \
+  --title "Demo video render" \
+  --content-type video/mp4
+```
+
+## Direct API Pattern
+
+If the helper is unavailable, use the same API shape:
+
+```sh
+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: $PAPERCLIP_RUN_ID" \
+  -F "file=@dist/demo.mp4;type=video/mp4"
+```
+
+Then create a work product when the uploaded file is the deliverable:
+
+```sh
+curl -sS -X POST \
+  "$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 @artifact-work-product.json
+```
+
+Use `type: "artifact"`, `provider: "paperclip"`, and metadata containing
+`attachmentId`, `contentType`, `byteSize`, `contentPath`, `openPath`,
+`downloadPath`, and `originalFilename`.

+## Agent Artifact Uploads
+
+When an agent generates a file that a board user or reviewer should inspect,
+attach it to the issue before marking the task complete. Do not rely on a local
+workspace path as the only access path.
+
+Use the helper from the repo root:
+
+```sh
+scripts/paperclip-upload-artifact.sh dist/demo.mp4 \
+  --title "Demo video render" \
+  --summary "MP4 render for board review"
+```
+
+For WebM output:
+
+```sh
+scripts/paperclip-upload-artifact.sh out/walkthrough.webm \
+  --title "Walkthrough video" \
+  --summary "WebM walkthrough render"
+```
+
+The helper uploads the file as an issue attachment, creates an artifact work
+product by default, and prints markdown links for the final issue comment. See
+`doc/AGENT-ARTIFACTS.md` for the full completion pattern and direct API shape.

 ## Default Agent Workspaces
 
 When a local agent run has no resolved project/session workspace, Paperclip falls back to an agent home workspace under the instance root:
