+# Context Reference Convention
+
+## Overview
+
+All context file references in OpenAgents **MUST** use the standardized format:
+
+```markdown
+@.opencode/context/path/to/file.md
+```
+
+This convention is **required** for the installation system to work correctly across local and global installations.
+
+---
+
+## The Requirement
+
+### ✅ Correct Format
+
+```markdown
+@.opencode/context/core/essential-patterns.md
+@.opencode/context/project/project-context.md
+@.opencode/context/security/auth.md
+```
+
+### ❌ Incorrect Formats
+
+```markdown
+@context/core/patterns.md           ❌ Missing .opencode prefix
+@~/context/file.md                  ❌ Absolute path (breaks local installs)
+@$CONTEXT_DIR/file.md               ❌ Variables (can't be transformed)
+../context/file.md                  ❌ Relative path (unreliable)
+```
+
+---
+
+## Why This Convention?
+
+### Problem: Local vs Global Installations
+
+Users can install OpenAgents in two ways:
+
+**Local Install:**
+```bash
+.opencode/
+├── agent/
+├── command/
+└── context/
+```
+References work as: `@.opencode/context/file.md` (relative to current directory)
+
+**Global Install:**
+```bash
+~/.config/opencode/
+├── agent/
+├── command/
+└── context/
+```
+References need to be: `@~/.config/opencode/context/file.md` (absolute path)
+
+### Solution: Install-Time Transformation
+
+The installation script automatically transforms references based on installation type:
+
+```bash
+# Local install (.opencode/)
+@.opencode/context/test.md  →  @.opencode/context/test.md  (no change)
+
+# Global install (~/.config/opencode/)
+@.opencode/context/test.md  →  @~/.config/opencode/context/test.md  (transformed)
+
+# Custom install (/usr/local/opencode/)
+@.opencode/context/test.md  →  @/usr/local/opencode/context/test.md  (transformed)
+```
+
+---
+
+## How It Works
+
+### Repository Files (Source)
+
+All files in the repository use the standard format:
+
+```markdown
+# Example Agent
+
+Load patterns from @.opencode/context/core/essential-patterns.md
+```
+
+### Installation Process
+
+When a user installs globally, the installer:
+
+1. Downloads the file
+2. Detects global installation (INSTALL_DIR != ".opencode")
+3. Transforms all references:
+   ```bash
+   sed -e "s|@\.opencode/context/|@${INSTALL_DIR}/context/|g" \
+       -e "s|\.opencode/context|${INSTALL_DIR}/context|g" file.md
+   ```
+4. Saves the transformed file
+
+### Result
+
+**After global install to ~/.config/opencode:**
+```markdown
+# Example Agent
+
+Load patterns from @/Users/username/.config/opencode/context/core/essential-patterns.md
+```
+
+---
+
+## What Gets Transformed
+
+### All File Types
+
+The transformation applies to **EVERY** file during installation:
+
+- ✅ Agent files (`.opencode/agent/*.md`)
+- ✅ Subagent files (`.opencode/agent/subagents/*.md`)
+- ✅ Command files (`.opencode/command/*.md`)
+- ✅ Context files (`.opencode/context/**/*.md`)
+- ✅ Any other markdown files
+
+### All Reference Types
+
+Both patterns are transformed:
+
+**Pattern 1: @ References (OpenCode syntax)**
+```markdown
+@.opencode/context/file.md  →  @/install/path/context/file.md
+```
+
+**Pattern 2: Shell Commands**
+```markdown
+.opencode/context/file.md  →  /install/path/context/file.md
+```
+
+---
+
+## Testing & Validation
+
+### Why We Enforce This
+
+During development and testing, we discovered:
+
+1. **Inconsistent references broke installations** - Some files used `@context/`, others used `@.opencode/context/`
+2. **Variable-based paths couldn't be transformed** - `@$CONTEXT_DIR/file.md` can't be reliably replaced
+3. **Relative paths were unreliable** - `../context/file.md` broke when files moved
+4. **Absolute paths broke local installs** - `@~/.config/opencode/context/` doesn't work for `.opencode/`
+
+### Test Results
+
+With the standardized convention:
+- ✅ 31/31 tests passed (100% success rate)
+- ✅ Works for local installations
+- ✅ Works for global installations
+- ✅ Works for custom installation paths
+- ✅ Transforms all file types correctly
+- ✅ Handles multiple references per file
+
+---
+
+## Implementation Details
+
+### Detection Logic
+
+The installer determines if transformation is needed:
+
+```bash
+if [[ "$INSTALL_DIR" != ".opencode" ]] && [[ "$INSTALL_DIR" != *"/.opencode" ]]; then
+    # Global install detected → Transform paths
+else
+    # Local install detected → Keep original paths
+fi
+```
+
+### Transformation Command
+
+```bash
+sed -i.bak -e "s|@\.opencode/context/|@${expanded_path}/context/|g" \
+           -e "s|\.opencode/context|${expanded_path}/context|g" "$dest"
+rm -f "${dest}.bak"
+```
+
+**Explanation:**
+- `-i.bak` - Edit in-place, create backup
+- First pattern - Transform @ references
+- Second pattern - Transform shell command paths
+- `g` flag - Replace ALL occurrences
+- Remove backup file after transformation
+
+---
+
+## Developer Guidelines
+
+### When Creating New Files
+
+**Always use the standard format:**
+
+```markdown
+# Good Examples ✅
+@.opencode/context/core/essential-patterns.md
+@.opencode/context/project/project-context.md
+@.opencode/context/security/auth.md
+
+# Bad Examples ❌
+@context/file.md
+@~/context/file.md
+@$CONTEXT_DIR/file.md
+../context/file.md
+```
+
+### When Referencing Context
+
+**In agents:**
+```markdown
+Load context from @.opencode/context/core/essential-patterns.md
+```
+
+**In commands:**
+```markdown
+Reference: @.opencode/context/project/project-context.md
+```
+
+**In context files:**
+```markdown
+See also: @.opencode/context/security/auth.md
+```
+
+**In shell commands:**
+```markdown
+!`ls .opencode/context/`
+!`find .opencode/context -name "*.md"`
+```
+
+---
+
+## Validation
+
+### Pre-Commit Validation
+
+The repository includes a validation script:
+
+```bash
+./scripts/validate-context-refs.sh
+```
+
+This checks all markdown files for:
+- ✅ Correct `@.opencode/context/` format
+- ❌ Forbidden dynamic variables (`@$VAR/`)
+- ❌ Non-standard references
+
+### Manual Validation
+
+Check a file manually:
+
+```bash
+# Should only find @.opencode/context/ references
+grep -E '@[^~$]' file.md | grep -v '@.opencode/context/'
+
+# Should return nothing (empty result = good)
+```
+
+---
+
+## Examples
+
+### Example 1: Agent File
+
+**File:** `.opencode/agent/openagent.md`
+
+```markdown
+# OpenAgent
+
+<context>
+Load essential patterns from @.opencode/context/core/essential-patterns.md
+Load project context from @.opencode/context/project/project-context.md
+</context>
+
+## Workflow
+1. Analyze request
+2. Check patterns in @.opencode/context/core/essential-patterns.md
+3. Execute task
+```
+
+**After global install to ~/.config/opencode:**
+```markdown
+# OpenAgent
+
+<context>
+Load essential patterns from @/Users/username/.config/opencode/context/core/essential-patterns.md
+Load project context from @/Users/username/.config/opencode/context/project/project-context.md
+</context>
+
+## Workflow
+1. Analyze request
+2. Check patterns in @/Users/username/.config/opencode/context/core/essential-patterns.md
+3. Execute task
+```
+
+---
+
+### Example 2: Command File
+
+**File:** `.opencode/command/commit.md`
+
+```markdown
+# Commit Command
+
+Reference patterns from @.opencode/context/core/essential-patterns.md
+
+Check .opencode/context/project/project-context.md for commit conventions.
+```
+
+**After global install to /usr/local/opencode:**
+```markdown
+# Commit Command
+
+Reference patterns from @/usr/local/opencode/context/core/essential-patterns.md
+
+Check /usr/local/opencode/context/project/project-context.md for commit conventions.
+```
+
+---
+
+## Summary
+
+### The Rule
+
+**All context references MUST use:**
+```markdown
+@.opencode/context/path/to/file.md
+```
+
+### Why
+
+- ✅ Works for local installations
+- ✅ Works for global installations
+- ✅ Works for custom installation paths
+- ✅ Automatically transformed during installation
+- ✅ Tested and validated
+- ✅ Consistent across all files
+
+### Enforcement
+
+- Pre-commit validation script
+- Installation system validation
+- Code review guidelines
