fix: resolve BudgetExceededError CLI traceback issues (fixes #1627)#1635
Conversation
- Add clean error handling for BudgetExceededError in CLI * Wrap agent execution calls with graceful error handling * Show user-friendly error messages instead of raw tracebacks * Exit with code 1 and provide clear remediation guidance - Add max_budget parameter to Agent constructor * Accept max_budget directly as convenience parameter * Automatically create/update ExecutionConfig with budget setting * Maintain full backward compatibility * Add proper parameter documentation Both fixes follow architecture guidelines and provide intuitive UX. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: praisonai-triage-agent[bot] <praisonai-triage-agent[bot]@users.noreply.github.com>

In-place mutation of resolved_exec violates agent isolation by modifying shared ExecutionConfig instances
resolved_exec.max_budget = max_budget (line 752) mutates the object returned by resolve_execution. Since resolve_execution returns the same ExecutionConfig instance that was passed in (line 1314-1315 in feature_configs.py), this silently modifies the caller's original object. Any other agent holding a reference to that shared config would observe the unexpected budget value — a direct violation of the no-shared-mutable-state principle.
Use dataclasses.replace() to create a new instance instead:

Use a single-line actionable budget error to meet CLI acceptance criteria.
The current output spans multiple lines; the issue acceptance criteria calls for a single-line user-facing message with exit code 1.

Remove unused BudgetExceededError import at line 4214.
The import from praisonaiagents.errors import BudgetExceededError is not used in the code block following line 4214. Error handling is properly delegated to _execute_agent_with_budget_handling, which already performs a guarded import with fallback (lines 4087–4092). The eager import at line 4214 is unnecessary and can fail on module/version mismatches, preventing the agent initialization code from running at all.

@MervinPraison — re-implemented per AGENTS.md in #1645. What I didRead Better approach (shipped in #1645)
Ready for review → #1645 |
…nt param bloat) (#1645) Re-implements the CLI UX half of reverted PR #1635 without the core SDK changes that violated AGENTS.md. ## What changed - Add _execute_agent_with_budget_handling(agent, method_name, *args, **kwargs) helper on PraisonAIApp: calls agent.<method_name>(...) and catches BudgetExceededError to print a single-line actionable CLI message and exit(1) instead of leaking a raw traceback. - Route all 17 agent.start(prompt) / agent.chat(prompt) / auto_rag.chat(prompt) call sites in the direct-prompt dispatch through the helper. Covers every display mode: silent, quiet, verbose, debug, jsonl, json, flow, editor, default. ## What is NOT changed (intentionally) - Zero edits to praisonaiagents (core SDK). - NO new 'max_budget=' parameter on Agent.__init__. - Users continue to configure budgets via the already-consolidated execution=ExecutionConfig(max_budget=...) pattern per AGENTS.md §5.3 'Parameter Consolidation'. ## Why wrapper-only AGENTS.md §4.1 reserves core SDK for protocols/hooks/adapters — CLI UX belongs in the wrapper. AGENTS.md §5.3 explicitly consolidates execution- related knobs (max_iter, max_rpm, max_budget, rate_limiter, ...) into ExecutionConfig precisely to avoid adding more top-level Agent params. ## Error message Points users to the correct API: Budget limit exceeded: <reason>. Hint: set budget via execution=ExecutionConfig(max_budget=1.00) on your Agent. Closes #1627 Co-authored-by: praisonai-bot <bot@praisonai.com>
