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).
