Feature Compatibility Matrices

Comprehensive comparison of feature support across OpenAgents Control (OAC), Claude Code, Cursor IDE, and Windsurf platforms. Use these matrices to understand conversion impact before migrating agent configurations.

Quick Reference - Platform Support Summary

Platform	Config Format	Structure	Multiple Agents	Skills	Hooks	Granular Perms
OAC	Markdown+YAML	Directory	✅	✅	✅	✅
Claude Code	JSON/Markdown	Directory	✅	✅	✅	❌
Cursor IDE	Plain text	Single file	❌	❌	❌	❌
Windsurf	JSON	Directory	✅	⚠️	❌	❌

Detailed Matrices

Tool/Permission Capabilities

Feature	OAC	Claude Code	Cursor IDE	Windsurf
bash/shell execution	✅	✅	✅	✅
file read	✅	✅	✅	✅
file write	✅	✅	✅	✅
file edit/patch	✅	✅	✅	✅
glob search	✅	✅	✅	✅
grep content search	✅	✅	✅	✅
task delegation	✅	✅	❌	⚠️
granular permissions	✅	❌	❌	❌
ask permissions	✅	❌	❌	❌
path pattern rules	✅	❌	❌	⚠️

Notes:

• Cursor has no task delegation - all work happens in a single agent
• All platforms reduce OAC granular permissions (allow/deny/ask per path) to binary on/off
• Windsurf's delegation is limited compared to Claude's full subagent system

Configuration Features

Feature	OAC	Claude Code	Cursor IDE	Windsurf
custom model selection	✅	✅	✅	✅
temperature control	✅	❌	⚠️	⚠️
maxSteps limit	✅	❌	❌	❌
agent disable/hidden	✅	⚠️	❌	⚠️
custom prompts	✅	✅	✅	✅
version metadata	✅	⚠️	❌	⚠️
author metadata	✅	⚠️	❌	⚠️
tags	✅	❌	❌	⚠️

Notes:

• Claude does not support temperature configuration
• Cursor has limited temperature range support
• Windsurf maps temperature to "creativity" setting (low/medium/high)
• maxSteps is OAC-exclusive

---

Context/Memory Features

Feature	OAC	Claude Code	Cursor IDE	Windsurf
external context files	✅	✅	❌	✅
context priority levels	✅	❌	❌	❌
context subdirectories	✅	✅	❌	✅
skills/modules system	✅	✅	❌	⚠️
context descriptions	✅	⚠️	❌	⚠️
dependency declarations	✅	✅	❌	⚠️

Notes:

• Cursor requires all context to be inline in .cursorrules
• OAC supports 4 priority levels: critical, high, medium, low
• Windsurf only supports high/low priority (medium/critical get degraded)
• Skills in Windsurf become basic context file references

---

Agent/Mode Features

Feature	OAC	Claude Code	Cursor IDE	Windsurf
multiple agents	✅	✅	❌	✅
primary/subagent modes	✅	✅	❌	⚠️
agent categories	✅	⚠️	❌	⚠️
event hooks	✅	✅	❌	❌
hook matchers	✅	✅	❌	❌
priority levels	✅ (4)	⚠️ (2)	❌	⚠️ (2)

Notes:

• Cursor merges all agents into a single .cursorrules file
• Hook events supported by Claude: PreToolUse, PostToolUse, PermissionRequest, AgentStart, AgentEnd
• Windsurf has limited mode distinction

Conversion Impact

Lossless Conversions

These conversions preserve all features without degradation:

From	To	Notes
Cursor	OAC	Full upgrade - gains all OAC features
Cursor	Claude	Gains hooks, skills, multiple agents
Cursor	Windsurf	Gains multiple agents, contexts
Claude	OAC	Full upgrade - gains granular permissions, temperature
Windsurf	OAC	Full upgrade - gains hooks, granular permissions

---

Lossy Conversions

These conversions result in feature loss or degradation:

From	To	What's Lost/Degraded
OAC	Claude	Temperature, maxSteps, granular permissions → binary
OAC	Cursor	Significant loss: hooks, skills, multiple agents, contexts (inline only), granular permissions
OAC	Windsurf	Hooks, granular permissions, context priority (4→2 levels), temperature → creativity
Claude	Cursor	Significant loss: hooks, skills, multiple agents, contexts
Claude	Windsurf	Hooks, temperature
Windsurf	Cursor	Multiple agents merged, skills lost, contexts inline only
Windsurf	Claude	Temperature mapping may be imprecise

Platform-Specific Notes

OpenAgents Control (OAC)

• Config location: .opencode/agent/ directory
• Format: Markdown files with YAML frontmatter
• Strengths: Full feature support, granular permissions, 4-level priorities
• Best for: Complex multi-agent workflows requiring fine-grained control

Claude Code

• Config location: .claude/ directory
• Primary config: .claude/config.json or .claude/agents/*.md
• Strengths: Full hooks support, skills system, multiple agents
• Limitations: No temperature control, binary permissions only
• Permission modes: default, acceptEdits, dontAsk, bypassPermissions

Cursor IDE

• Config location: .cursorrules (single file in project root)
• Format: Plain text with optional YAML frontmatter
• Strengths: Simple setup, universal tool support
• Limitations: Single agent only, no external contexts, no hooks/skills
• Best for: Simple, single-purpose project rules

Windsurf

• Config location: .windsurf/ directory
• Primary config: .windsurf/config.json
• Strengths: Multiple agents, context files, creativity settings
• Limitations: No hooks, binary permissions, 2-level priority only
• Temperature mapping: ≤0.4 → low, 0.4-0.8 → medium, >0.8 → high
