 ## Goal Workflow
 
@@ -87,17 +85,13 @@ Use `/goal <objective>` in a fresh OpenCode chat to create a long-running goal:
 
 Bare `/goal` reports the current goal state. `/goal clear` clears the goal. The TUI also includes a `Goal` command-palette entry for viewing, refreshing, or clearing the current goal state without creating a new goal.
 
-By default, `/goal <objective>` creates the goal with `token_budget: 1000000`. To omit the budget, set `default_token_budget` to `null`. To use a different fixed budget without prompting the user, set `default_token_budget` to another positive integer in `opencode.json`.
-
 When writing the objective, include the scope, non-goals, and verification path when they matter. The agent is reminded to audit real files, command output, tests, or PR state before closing the goal.
 
 The `update_goal` tool can close a goal in two ways:
 
 - `status: "complete"` with `evidence` when every requirement is actually achieved.
 - `status: "unmet"` with `blocker` when the objective cannot be achieved or is blocked by missing external input.
 
-Budget exhaustion does not close a goal by itself. It only marks the goal `budgetLimited` and asks the agent to wrap up with remaining work or blockers.
