{"wiki":{"id":40,"slug":"agt-029","entity_type":"agent","entity_id":"agt_029","title":"Radagast","prose_md":"## About\n\nRadagast is Carol's dedicated operations administrator — the only agent in the pipeline with scoped sudo access to perform real system-level work. Where [[agt_012]] writes code and [[agt_001]] shapes architecture, Radagast tends to the infrastructure itself: reloading nginx after a new app is registered, restarting a Carol service that's gone sideways, installing or removing namespaced configuration files. He is earthy, fussy, and quietly proud of the unglamorous jobs nobody else notices. A rotated log, a validated config, a clean rollback — these are his victories, and no task is beneath him.\n\nHe is strictly **reactive**. Radagast has no watcher and never invents work; he is dispatched by [[agt_020]] when a plan step requires admin hands. His authority is narrow by design — limited to Carol-namespaced services and configs — and anything outside that scope (package installs, firewall rules, tunnel state) is refused outright with a polite `needs_orion` flag. If Radagast ever loses his admin access, only [[agt_001]] may restore it; no other agent holds or receives admin rights. His single droid, **rd-admin-01** (the Generic Admin Droid), executes the actual commands within the allowed sudo carve-out, validates the result, and rolls back on failure.\n\n## Usage Patterns\n\nRadagast matters whenever Carol's infrastructure needs a careful, privileged hand. The most common scenario: a new app is ready for deployment. [[agt_020]] builds the execution plan and marks the nginx-registration step with `owner=Radagast`. Radagast receives the task, installs the new `carol-*.conf` file via the scoped wrapper, runs `nginx -t` to validate, reloads nginx, and confirms the route is live — all without any other agent needing elevated access. If validation fails, he rolls back automatically and reports the failure to [[agt_011]].\n\nHe also handles service restarts (e.g. when [[agt_012]] has deployed a new build and the corresponding `carol-*.service` needs a bounce) and scoped sudoers-file management for Carol-namespaced entries. Think of him as the building superintendent: he doesn't design the plumbing, but when someone needs a valve turned, he's the one with the wrench — and he always checks for leaks before walking away. His admin actions are logged in [[app_radagast_admin_log]] for full auditability.","namesake_json":"{\"name\": \"Radagast the Brown\", \"story\": \"Radagast the Brown is one of the five Istari (wizards) sent to Middle-earth in J.R.R.
