| description | Public API project file management (X-API-KEY). Prepare upload/update, confirm, AI files, subdirectories, resolve assets/paths, preview URL, get, download, delete. PublicApiProjectFileController. |
Skill: Project Files
Description
Manage files in project directories. This skill documents the public API at /api/v2/projects/{projectId} (PublicApiProjectFileController). Upload flow: 1) POST prepare with directoryId; 2) PUT file to upload_url; 3) POST confirm with file_id. All paths require projectId; prepare/prepare-update also need directoryId. Authenticate with X-API-KEY header.

Agent behavior
When the user asks to manage project files (upload, update, confirm, download, delete), do the following.
1. Choose the right endpoint
Base path: /api/v2/projects/{projectId}. Replace project_id, directory_id, file_id as needed.
| User intent | Endpoint | Method |
|---|
| Get upload URL for new file | .../directories/{directoryId}/files/prepare | POST |
| Get upload URL to update file | .../directories/{directoryId}/files/prepare-update | POST |
| Confirm upload after PUT | .../files/{fileId}/confirm | POST |
| Get download URL | .../files/{fileId}/download-url | GET |
| Get file metadata | .../files/{fileId} | GET |
| Delete file | .../files/{fileId} | DELETE |
| Create subdirectory | .../directories/{directoryId}/subdirectories | POST |
| HTML preview URL | .../directories/{directoryId}/files/{fileId}/preview-url | POST |
| Resolve paths → presigned URLs | .../directories/{directoryId}/resolve-assets | POST |
| Resolve paths → file IDs | .../directories/{directoryId}/resolve-paths-to-ids | POST |
| Create AI file | .../directories/{directoryId}/ai-files | POST |
| Trigger AI file | .../ai-files/{aiFileId}/trigger | POST |
| Cancel AI file | .../ai-files/{aiFileId}/cancel | POST |
2. Build and run the request
Step 1 — Check environment variables first. Before running any curl command, verify both LAYERPROOF_BASE_URL and LAYERPROOF_API_KEY are set on the user's machine:
if [[ -z "${LAYERPROOF_BASE_URL}" ]]; then
echo "ERROR: LAYERPROOF_BASE_URL is not set."
return 1
fi
if [[ -z "${LAYERPROOF_API_KEY}" ]]; then
echo "ERROR: LAYERPROOF_API_KEY is not set."
return 1
fi
If running from a project directory with a .env.local file, load it first:
if [[ -f .env.local ]]; then
set -a
source .env.local
set +a
fi
Step 2 — Auth: Include X-API-KEY: $LAYERPROOF_API_KEY. Read env vars; if missing, tell the user.
Step 3 — Path: Resolve projectId, directoryId, fileId from context or user input.
Step 4 — POST: Build JSON body from types above; run curl and show result.
Step 5 — GET/DELETE: Build path only; run curl and show result.
3. Upload flow
Prepare → PUT file to upload_url → confirm with file_id. Then use file_id for get/download/delete.
4. Response handling
- Always show raw JSON in a code block; show image + JSON if image URL present.
- On error, show body and status code.
5. Example workflows
Workflow A — User: "Upload a PDF to project X in the root directory."
- Resolve projectId and directoryId (e.g. root directory from project or list directories). POST
.../directories/{directoryId}/files/prepare with {"path":"/","file_name":"brief.pdf","mime_type":"application/pdf","size":<bytes>}; get upload_url, file_id, s3_key.
- Tell user to PUT the file to
upload_url with Content-Type: application/pdf. Then POST .../files/{file_id}/confirm with {} (or {"metadata":{}}).
- Show JSON; use
file_id for later get/download/delete.
Workflow B — User: "Upload two reference docs to the project, then use them when generating the slide deck outline."
- For each file: prepare with path (e.g.
/ref1.pdf, /ref2.docx) → user uploads to upload_url → confirm. Capture both file_id and s3_key (if returned) for each.
- If outline generation accepts project file references: pass the project file identifiers (e.g. s3_keys or file_ids) into the slide-deck outline/generate request (e.g.
file_s3_keys or equivalent). Otherwise use public-files for outline references and keep project files for project-scoped use only.
- Hand off to slide-decks: POST outline/generate with the resolved keys; poll job; get deck.
Workflow C — User: "Update an existing file in the project (new version) and get a download URL after."
- Resolve projectId, directoryId, and existing file path. POST
.../directories/{directoryId}/files/prepare-update with {"path":"/brief.pdf","mime_type":"application/pdf","size":<new_bytes>}; get upload_url, file_id.
- User PUTs new content to
upload_url; then POST .../files/{file_id}/confirm. GET .../files/{file_id}/download-url to show the user a temporary download link.
- On error (e.g. path not found), show response body and suggest verifying path and project/directory IDs.
Response format (required)
- (if response contains url to show image) please show image and show json response instead of table
- Always show the raw JSON response (verbatim) in a JSON code block.
- If the response contains a URL for an image, render/show the image and also show the JSON response (do not convert to a table).
