What is manage-file-storage?

Configuration guidance for changing or removing file storage, including S3-compatible services such as MinIO, Cloudflare R2, and DigitalOcean Spaces. S3 is a common interface for storing files in buckets.

Use it to switch storage providers, configure a new bucket, or remove file, avatar, and MinIO-related infrastructure.

It shows which settings and code areas must change when moving stored files to another service or removing file storage from an application.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.00512
Opus 5	$0.00007	$0.00256
Sonnet 5	$0.00003	$0.00102
Haiku 4.5	$0.00001	$0.00051

Security

Grade A, and why

manage-file-storage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Swaps S3 provider or removes file storage entirely.

Swap S3 Provider (Cloudflare R2, DigitalOcean Spaces, etc.)

No code changes needed - S3FileStorageService uses the standard S3 API. Only configuration:

Set the FileStorage__* environment variables on your API container:

# Cloudflare R2
FileStorage__Endpoint=https://<account-id>.r2.cloudflarestorage.com
FileStorage__AccessKey=<R2-access-key>
FileStorage__SecretKey=<R2-secret-key>
FileStorage__BucketName=my-bucket
FileStorage__UseSSL=true
FileStorage__Region=auto

# DigitalOcean Spaces
FileStorage__Endpoint=https://<region>.digitaloceanspaces.com
FileStorage__AccessKey=<spaces-key>
FileStorage__SecretKey=<spaces-secret>
FileStorage__BucketName=my-space
FileStorage__UseSSL=true
FileStorage__Region=<region>

Pre-create the bucket in your provider's console. Restart - no rebuild needed.

Remove File Storage Entirely

Infrastructure: Remove the MinIO resource from MyProject.AppHost/Program.cs
Backend: Remove Application/Features/FileStorage/, Application/Features/Avatar/, Infrastructure/Features/FileStorage/, Infrastructure/Features/Avatar/
Entity: Remove HasAvatar from ApplicationUser
Endpoints: Remove avatar endpoints from UsersController, UploadAvatar/ DTOs
DTOs: Remove HasAvatar from UserOutput, AdminUserOutput, UserResponse, AdminUserResponse, mappers
DI: Remove AddFileStorageServices() and AddAvatarServices() from Program.cs
NuGet: Remove AWSSDK.S3, SkiaSharp, SkiaSharp.NativeAssets.Linux.NoDependencies from Directory.Packages.props
Frontend: Remove AvatarDialog.svelte, update ProfileHeader.svelte and UserNav.svelte to remove avatar image
Config: Remove FileStorage section from all appsettings*.json
Health check: Remove S3 health check from HealthCheckExtensions.cs

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
