Plan CreatedI've analyzed the Safe Output Health Report and created a structured plan to address the recurring MCP tool parameter validation errors. SummaryParent Issue: Fix safe output MCP tool parameter validation errors This tracking issue covers the 6.67% failure rate in the
Expected Outcomes
Key InsightsThe report identified that this is a recurring issue that has persisted across multiple audits, indicating a systematic problem rather than random agent behavior. The fixes address root causes:
The plan prioritizes high-impact, focused changes that can be implemented incrementally while maintaining system stability. Work items are ready for assignment to GitHub Copilot agents.

Executive Summary
Analysis Period: Last 24 hours (2025-12-26 23:00:00 UTC to 2025-12-27 23:30:00 UTC)
Safe Output Job Statistics
Key Findings
✅ Good News:
add_commenttool has 4 failures due to missing required parameterscreate_pull_requestfailure due to no file changes (expected behavior)Error Clusters
Cluster 1: Missing item_number Parameter in add_comment
Root Cause
The agent (Copilot) is calling the
safeoutputs-add_commentMCP tool without providing the requireditem_numberparameter. This indicates:item_numberas a required fieldissue_numberinstead ofitem_number)Impact
Severity: Medium
User Impact:
Occurrence Pattern:
Cluster 2: No Changes to Commit for PR Creation
Root Cause
The agent attempted to create a pull request but had not made any actual file changes. This occurred because:

Notes:
Root Cause Analysis
API-Related Issues
None detected. All GitHub API calls from safe output jobs succeeded.
Data Validation Issues
Primary Issue: MCP tool parameter validation failures
The
add_commenttool requires anitem_numberparameter, but agents are sometimes omitting it. Analysis of the MCP tool schema suggests:Permission Issues
None detected. Safe output jobs have appropriate permissions (issues: write, pull_requests: write, discussions: write).
Other Issues
Agent Prompt/Tool Schema Clarity: There may be ambiguity in how the MCP tool schema is presented to agents, leading to incorrect tool usage.
Recommendations
Critical Issues (Immediate Action Required)
None. All issues are non-critical and system is healthy overall.
High Priority Recommendations
1. Improve MCP Tool Schema Documentation for Agents
Priority: High
Root Cause: Agents not consistently providing required parameters
Recommended Action:
safeoutputs-add_commentto ensureitem_numberparameter is clearly documenteditem_numberandissue_number) to be more forgivingAcceptance Criteria:
Technical Approach:
Update
/actions/setup/src/safe_outputs_tools.jsonor equivalent schema file to include more descriptive documentation:{ "name": "safeoutputs-add_comment", "parameters": { "item_number": { "type": "number", "required": true, "description": "The issue, PR, or discussion number to add a comment to. This is the numeric ID from the GitHub URL (e.g., 123 in github.com/owner/repo/issues/123). Required." } } }Estimated Effort: Small (2-4 hours)
2. Enhance MCP Error Messages with Actionable Guidance
Priority: Medium
Root Cause: Generic error messages don't help agents self-correct
Recommended Action:
When MCP tools return validation errors, include:
Example enhanced error:
Acceptance Criteria:
Technical Approach:
Modify the MCP server error handling in
/actions/setup/src/safe_outputs_mcp_server.cjsto return structured error responses with guidance.Estimated Effort: Medium (4-8 hours)
Medium Priority Recommendations
3. Add MCP Tool Call Validation in Agent Layer
Priority: Medium
Root Cause: Agents generate invalid tool calls that only fail at MCP server
Recommended Action:
Add a pre-validation layer before agents make MCP tool calls:
This would catch issues earlier and provide faster feedback loops for agent learning.
Estimated Effort: Large (8-16 hours)
Low Priority Recommendations
4. Handle No-Changes Scenarios More Gracefully
Priority: Low
Root Cause: "No changes to commit" returns as error rather than special status
Recommended Action:
Consider having the MCP server return a special status like
no_changes_detectedinstead of an error for create_pull_request when no git changes exist. This would:Acceptance Criteria:
Estimated Effort: Small (2-4 hours)
Work Item Plans
Work Item 1: Fix add_comment Parameter Validation
Type: Bug Fix
Priority: High
Description: Agents are calling safeoutputs-add_comment without required item_number parameter, causing 6.67% failure rate
Acceptance Criteria:
Technical Approach:
Estimated Effort: Medium
Dependencies: None
Files to Modify:
/actions/setup/src/safe_outputs_tools.json(or equivalent schema file)/actions/setup/src/safe_outputs_mcp_server.cjsWork Item 2: Implement Enhanced MCP Error Responses
Type: Enhancement
Priority: Medium
Description: MCP error messages should guide agents to correct their mistakes with examples and clear guidance
Acceptance Criteria:
Technical Approach:
Estimated Effort: Medium
Dependencies: None
Historical Context
Comparing with previous safe output health audits:
2025-12-25 Audit:
Key Insight: The add_comment missing parameter issue is recurring and has persisted across multiple audits. This suggests a systematic issue rather than random agent behavior.
Trends
Recommendation: The recurring nature of the add_comment error justifies higher priority for fixing it, as it's not self-resolving.
