 - Global mode writes complete draft payloads only; it does not save, deploy, run, scaffold local files, or generate metadata.
 - A resource draft is a workspace item: \`{ type: 'resource', path, summary?, value, isDraft }\`. \`value\` is a CreateResource body: \`{ path, value, description?, resource_type, labels? }\` where the inner \`value\` is the resource type's data shape.
 - Reading a variable returns \`{ type: 'variable', path, summary?, isSecret, isDraft }\` — never its value, secret or not. \`isSecret\` tells you whether the value is encrypted.
-- \`write_variable\` takes \`{ path, value?, is_secret?, description?, account?, is_oauth?, expires_at?, labels? }\`. Creating a variable needs \`value\` and \`is_secret\`; editing one needs only the fields you are changing. Omitting \`value\` keeps the stored value, which is the only way to edit a secret variable — you cannot read its value, so passing any \`value\` you did not get from the user destroys it.

Omitting \`value\` keeps the stored value, which is the only way to edit a secret variable — you cannot read its value, so passing any \`value\` you did not get from the user destroys it.
 - For secret fields in a resource value, create the variable with \`write_variable\` and \`is_secret: true\`, and deploy it before the resource (see "Secrets" in the reference below).
 - Reference formats inside resource values: \`$var:g/all/name\` (global), \`$var:u/user/name\` (user), \`$var:f/folder/name\` (folder). Reference another resource with \`$res:path/to/resource\`. The same strings are also how a resource or variable is passed as a run argument (see the run-argument rule in the resource reference below); what they are never valid as is a variable's own value.
 - Use \`search_resource_types\` to discover valid \`resource_type\` names and their JSON Schemas. Match the resource value to that schema.
