- Reword the attachment line in the execute description: attachments are opaque media handles you forward to the user, not byte-readable in code. - Strip the hardcoded tools.$rune.search/describe block from the runtime's instructions(): discovery is not a runtime feature (the embedder registers and documents it), and the baked-in object-arg form contradicted code mode's positional API. Removes the only prompt discrepancy. - Make the runtime's unknown-tool suggestion generic instead of naming $rune. Discovery is now documented in exactly one place (code-mode describe()).
