+# Agent Container Utilities Audit
+
+**Last Updated**: 2026-01-27  
+**Related Issue**: #11970
+
+This document provides a comprehensive audit of `/usr/bin` utilities used in agentic workflows, with recommendations for mounting into the agent container.
+
+## Overview
+
+The agent container currently mounts only three utilities from `/usr/bin`:
+- `/usr/bin/date` - Date/time operations
+- `/usr/bin/gh` - GitHub CLI
+- `/usr/bin/yq` - YAML processor
+
+This audit identifies additional utilities commonly used in workflows and provides categorized recommendations for container mounting.
+
+## Methodology
+
+The audit analyzed:
+1. **184 workflow files** in `.github/workflows/*.md`
+2. **Usage frequency** of common utilities via pattern matching
+3. **Lock file analysis** to identify current mounts
+4. **Ubuntu runner image** available utilities (from `specs/ubuntulatest.md`)
+
+## Usage Frequency Analysis
+
+The following table shows utility usage frequency in workflow markdown files:
+

+## Security Considerations
+
+### Risk Categories
+
+| Risk Level | Description | Examples |
+|------------|-------------|----------|
+| **Low** | Read-only or sandboxed operations | `cat`, `grep`, `wc`, `jq` |
+| **Medium** | Network access or command execution | `curl`, `wget`, `git`, `xargs` |
+| **High** | System modification, privilege escalation | `sudo`, `chown`, system utilities |
+
+### Mitigation Strategies
+
+1. **Read-Only Mounts**: All `/usr/bin` mounts use `:ro` (read-only)
+2. **Network Firewall**: Workflows define allowed domains, blocking unauthorized network access
+3. **Workspace Sandboxing**: File operations are restricted to the workspace directory
+4. **Environment Control**: Sensitive data passed via environment variables, not command arguments
+
+### Utilities NOT Recommended for Mounting
+
+| Utility | Reason |
+|---------|--------|
+| `sudo` | Privilege escalation risk |
+| `chown` | Ownership manipulation |
+| `mount` | Filesystem manipulation |
+| `passwd` | User credential modification |
+| `ssh` | Direct remote access (use gh CLI instead) |
+| `nc`/`netcat` | Raw network access |
+| `dd` | Low-level disk operations |
+
+## Implementation Recommendations
+
+### Immediate (Priority 1)
+
+Add these utilities to `copilot_engine_execution.go`:
+
+```go
+// Essential utilities for most workflows
+awfArgs = append(awfArgs, "--mount", "/usr/bin/jq:/usr/bin/jq:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/grep:/usr/bin/grep:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/cat:/usr/bin/cat:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/curl:/usr/bin/curl:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/find:/usr/bin/find:ro")
+```
+
+### Short Term (Priority 2)
+
+Add commonly used utilities:
+
+```go
+// Common utilities for file operations
+awfArgs = append(awfArgs, "--mount", "/usr/bin/which:/usr/bin/which:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/mkdir:/usr/bin/mkdir:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/wc:/usr/bin/wc:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/head:/usr/bin/head:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/tail:/usr/bin/tail:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/sort:/usr/bin/sort:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/diff:/usr/bin/diff:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/cp:/usr/bin/cp:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/ls:/usr/bin/ls:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/sed:/usr/bin/sed:ro")
+awfArgs = append(awfArgs, "--mount", "/usr/bin/cut:/usr/bin/cut:ro")
+```
+
+### Long Term (Priority 3)
+
+Consider a configuration-based approach allowing workflows to specify required utilities:
+
+```yaml
+---
+engine: copilot
+sandbox:
+  utilities:
+    - jq
+    - curl
+    - tar
+    - zip
+---
+```
+
+## Summary
+
+This audit identifies **28 utilities** commonly used in agentic workflows:
+- **6 Essential**: `jq`, `grep`, `cat`, `curl`, `find`, `git`
+- **10 Common**: `which`, `mkdir`, `wc`, `head`, `tail`, `sort`, `diff`, `cp`, `ls`, `sed`, `awk`, `cut`
+- **12 Optional**: `file`, `rm`, `chmod`, `zip`, `unzip`, `mv`, `wget`, `touch`, `xargs`, `base64`, `tar`, `tee`, `stat`
+
+The current configuration (only `date`, `gh`, `yq`) is insufficient for most workflows. Adding the essential and common utilities would significantly improve workflow compatibility while maintaining security through read-only mounts and existing network controls.
