Remove unused enabledTools variable from safe outputs prompt generation

[Copilot]

Fix: Prevent Tool Names in Safe Outputs Prompt ✅

Issue: #12437 - Tool names in safe outputs prompt cause agent failures

🎯 Solution Summary

Removed unused enabledTools variable that was a remnant of old buggy code. The code now cleanly generates a prompt that instructs agents to query the MCP server for available tools, instead of listing them directly.

📝 Changes Made

1. pkg/workflow/unified_prompt_step.go

   • ❌ Removed: enabledTools := GetEnabledSafeOutputToolNames(data.SafeOutputs)
   • ❌ Removed: Unnecessary if len(enabledTools) > 0 check
   • ✅ Simplified: Direct prompt generation without unused variables

2. pkg/workflow/safe_outputs_config_helpers.go

   • ✅ Updated: Function documentation to explicitly state tool names should NOT be in prompts
   • ✅ Clarified: Function purpose is only for tools.json generation and logging

3. pkg/workflow/prompts_test.go

   • ✅ Added: TestSafeOutputsPrompt_NeverListsToolNames() regression test
   • ✅ Tests: Verifies forbidden tool names never appear in prompt
   • ✅ Validates: Correct MCP query instruction is present

4. Merged main branch (as requested)

   • ✅ Merged main branch (up to commit 3d561d8)
   • ✅ Resolved conflicts by accepting main branch changes
   • ✅ Recompiled all 147 workflows successfully

✅ Test Results

TestSafeOutputsPrompt_NeverListsToolNames           PASS
TestGenerateSafeOutputsPromptStep_IncludesWhenEnabled  PASS
TestGenerateSafeOutputsPromptStep_SkippedWhenDisabled PASS
All safe outputs tests                               PASS
All unified prompt tests                             PASS
make fmt                                             PASS
make lint                                            PASS
make recompile                                       PASS (147/147 workflows)

📊 Impact

• ✅ Zero functional change: Prompt text was already correct
• ✅ Cleaner code: Removed confusing pattern
• ✅ Future-proof: Regression test prevents bug from returning
• ✅ Better docs: Clear guidance on function usage
• ✅ Up to date: Merged with latest main branch changes

🎨 Generated Prompt (Verified)

<safe-outputs>
<description>GitHub API Access Instructions</description>
<instructions>
Discover available tools from the safeoutputs MCP server.
</instructions>
</safe-outputs>

No tool names listed ✅ (e.g., no "create_issue", "add_comment", etc.)

🔐 Security Impact

Prevents agents from attempting premature tool access before MCP initialization completes, which causes failures and potential security issues.

This section details on the original issue you should resolve

<issue_title>Tool names in the safe outputs prompt (again)</issue_title>
<issue_description>Including tool names in the safeoutputs prompt causes the agent to access the tools and fail. THe prompt should instruct the agent to query MCP to get safeoutputs tools. This bug has been previously fixed and seems to be back.

GitHub API Access Instructions The gh CLI is NOT authenticated. Do NOT use gh commands for GitHub operations. To create or modify GitHub resources (issues, discussions, pull requests, etc.), you MUST call the appropriate safe output tool. Simply writing content will NOT work - the workflow requires actual tool calls.

Available tools: add_comment, add_labels, create_issue, missing_tool, noop

Critical: Tool calls write structured data that downstream jobs process. Without tool calls, follow-up actions will be skipped.
