Read this brief and inventory the materials actually available: [PASTE BRIEF]. INPUTS: [ATTACHED FILES OR AUTHORIZED LINKS].
For each input, state whether you accessed its content, saw only metadata, or could not access it. Then identify which required actions your current tools support: reading, image inspection, file creation, code execution, connected-app edits, and publishing. Do not claim a capability because another version of the product offers it.
Return: available inputs; missing essentials; actions you can perform; actions requiring me; and one supported fallback for each blocked action. Do not expose secrets. Continue with useful independent preparation, but do not pretend a blocked external action happened.
