Cloudflare R2#

Operate Cloudflare R2 through your OOMOL-connected account. This skill calls the cloudflare_r2 connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action#

Assume the user has already installed the oo CLI, signed in, and connected Cloudflare R2. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

bash

oo connector schema "cloudflare_r2" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

bash

oo connector run "cloudflare_r2" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

Available actions#

• add_custom_domain — Attach a custom domain from a Cloudflare zone to an R2 bucket. [write]

• get_custom_domain — Get the settings of one custom domain attached to an R2 bucket.
• get_event_notification_rules — Get the event notification rules that send R2 bucket events to one queue.

• get_sippy_config — Get the Sippy incremental migration configuration of an R2 bucket.
• list_accounts — List Cloudflare accounts visible to the current credential.
• list_bucket_jobs — List background jobs for an R2 bucket, such as prefix delete jobs.
• list_buckets — List the R2 buckets in a Cloudflare account.
• list_custom_domains — List the custom domains attached to an R2 bucket.
• list_event_notification_rules — List every event notification rule of an R2 bucket grouped by target queue.
• list_objects — List objects in an R2 bucket with optional prefix, delimiter grouping, and cursor pagination.
• put_object — Upload one R2 object from a public URL, plain text, or base64-encoded content. [destructive]
• update_bucket — Update mutable R2 bucket properties such as default storage class or jurisdiction. [write]
• update_bucket_cors_policy — Replace the bucket-level CORS policy for an R2 bucket. [destructive]

• update_bucket_lock — Replace the object lock rules of an R2 bucket with the given rule set. [destructive]
• update_custom_domain — Update the public access, TLS version, or cipher settings of a custom domain. [write]
• update_managed_domain — Enable or disable public access to an R2 bucket through its r2.dev domain. [destructive]

Safety#

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change Cloudflare R2 state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup#

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md): bash

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  
  

  powershell

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  
  

• Not signed in / authentication error — sign in to your OOMOL account once: bash

  oo auth login
  
  

• scope_missing / credential_expired / app_not_ready / app_not_found — Cloudflare R2 is not connected, or the connection expired or lacks a scope. Connect once (auth type: custom credential, OAuth2) at: text

  https://console.oomol.com/app-connections?provider=cloudflare_r2
  
  

• HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
