## Root Cause
Execution a40bdb4a-964d-4684-94e8-b148eb6bcfc2 and all similar
executions have been failing since Nov 12, 2025 when tool pin routing
was refactored to use node IDs. The SmartDecisionMakerBlock was
double-sanitizing field names when emitting tool call outputs:
```python
# Original field name from link: "Max Keyword Difficulty"
original_field_name = field_mapping.get(clean_arg_name) # ✅ Retrieved correctly
sanitized_arg_name = self.cleanup(original_field_name) # ❌ Sanitized AGAIN!
emit_key = f"tools_^_{node_id}_~_{sanitized_arg_name}" # Emits "max_keyword_difficulty"
```
But the parser expected original names from graph links:
```python
# Parser expects: "Max Keyword Difficulty" (from link.sink_name)
# Emit provides: "max_keyword_difficulty" (sanitized)
# Result: Mismatch → Tool never executes
```
### Changes 🏗️
**1. Fixed Emit Logic** (`smart_decision_maker.py` line 1135)
- Removed double sanitization: `sanitized_arg_name =
self.cleanup(original_field_name)`
- Now emits with original field names: `emit_key =
f"tools_^_{node_id}_~_{original_field_name}"`
**2. Made Agent Nodes Consistent** (`smart_decision_maker.py` lines
497-530)
- Added `field_mapping` to agent function signatures (was missing)
- Agent signatures now sanitize property keys for Anthropic API (like
block signatures)
- Stores field_mapping for use during emit
### Impact
**Fixes:**
- ✅ All graphs with multi-word field names (e.g., "Max Keyword
Difficulty", "Minimum Volume")
- ✅ All graphs with special characters in field names (e.g., "API-Key")
- ✅ Both block nodes AND agent nodes now work consistently
**Unaffected:**
- Single-word lowercase field names (e.g., "keyword", "url") - these
were already working
### Checklist 📋

- [x] I have tested my changes according to the test plan:
- [x] Verified parse_execution_output handles exact match correctly
- [x] Verified emit uses original field names
- [x] Verified field_mapping works for both block and agent nodes

changes (no changes)
- [x] No configuration changes in this PR
### Test Plan
1. **Unit test validation** (completed):
- Field name cleanup: "Max Keyword Difficulty" →
"max_keyword_difficulty" ✅
- Parse with exact match: Success ✅
- Parse with mismatch: Returns None ✅
2. **Production validation** (to be done after deployment):
- Re-run execution a40bdb4a-964d-4684-94e8-b148eb6bcfc2
- Verify AgentExecutor (node 767682f5-694f-4b2a-bf52-fbdcad6a4a4f)
executes successfully
- Verify execution completes with high correctness score (not 0.20)
- Monitor for any regressions in existing graphs
### Files Changed
- `backend/blocks/smart_decision_maker.py`: Remove double sanitization,
add agent field_mapping
### Related Issues
- Resolves execution failure a40bdb4a-964d-4684-94e8-b148eb6bcfc2

🧱 AutoGPT Frontend
The AutoGPT frontend is where users interact with our powerful AI automation platform. It offers multiple ways to engage with and leverage our AI agents. This is the interface where you'll bring your AI automation ideas to life:
Agent Builder: For those who want to customize, our intuitive, low-code interface allows you to design and configure your own AI agents.
Workflow Management: Build, modify, and optimize your automation workflows with ease. You build your agent by connecting blocks, where each block performs a single action.
Deployment Controls: Manage the lifecycle of your agents, from testing to production.
Ready-to-Use Agents: Don't want to build? Simply select from our library of pre-configured agents and put them to work immediately.
Agent Interaction: Whether you've built your own or are using pre-configured agents, easily run and interact with them through our user-friendly interface.
Monitoring and Analytics: Keep track of your agents' performance and gain insights to continually improve your automation processes.
Read this guide to learn how to build your own custom blocks.
💽 AutoGPT Server
The AutoGPT Server is the powerhouse of our platform This is where your agents run. Once deployed, agents can be triggered by external sources and can operate continuously. It contains all the essential components that make AutoGPT run smoothly.
Source Code: The core logic that drives our agents and automation processes.
Infrastructure: Robust systems that ensure reliable and scalable performance.
Marketplace: A comprehensive marketplace where you can find and deploy a wide range of pre-built agents.
🐙 Example Agents
Here are two examples of what you can do with AutoGPT:
-
Generate Viral Videos from Trending Topics
- This agent reads topics on Reddit.
- It identifies trending topics.
- It then automatically creates a short-form video based on the content.
-
Identify Top Quotes from Videos for Social Media
- This agent subscribes to your YouTube channel.
- When you post a new video, it transcribes it.
- It uses AI to identify the most impactful quotes to generate a summary.
- Then, it writes a post to automatically publish to your social media.
These examples show just a glimpse of what you can achieve with AutoGPT! You can create customized workflows to build agents for any use case.

🛠️ Build your own Agent - Quickstart
🏗️ Forge
Forge your own agent! – Forge is a ready-to-go toolkit to build your own agent application. It handles most of the boilerplate code, letting you channel all your creativity into the things that set your agent apart. All tutorials are located here. Components from forge can also be used individually to speed up development and reduce boilerplate in your agent project.
🚀 Getting Started with Forge – This guide will walk you through the process of creating your own agent and using the benchmark and user interface.
📘 Learn More about Forge
🎯 Benchmark
Measure your agent's performance! The agbenchmark can be used with any agent that supports the agent protocol, and the integration with the project's CLI makes it even easier to use with AutoGPT and forge-based agents. The benchmark offers a stringent testing environment. Our framework allows for autonomous, objective performance evaluations, ensuring your agents are primed for real-world action.
