[FEATURE] Add --context flag to load initial context from file

[jwesleye]

Feature Description

Load initial context from a file before starting the conversation.

Problem/Motivation

I often need to provide the same background context (project specs, codebase overview) at the start of each session.

Proposed Solution

chat_loop myagent --context project_context.md

# First message automatically includes file contents
# Useful for:
# - Project specifications
# - Codebase overviews
# - Style guides
# - Background information

Benefits

• Consistent context across sessions
• Share context files with team
• Document-driven conversations
• Reduces repetitive setup

Priority

• Critical
• High
• Medium
• Low

✅ Already Implemented

This feature is already available through the prompt template system!

Current Implementation

You can load initial context from files using prompt templates:

Option 1: Direct template with file content

# Create a template that loads your context
cat > ~/.prompts/load.md <<'EOF'
# Load Context

Please read and understand the following context:

{input}
EOF

# Use it in conversation
chat_loop myagent
You: /load $(cat project_context.md)

Option 2: Pipe file contents

# Simply paste or type file contents as first message
chat_loop myagent
You: Here's the project context:
You: \\
... [paste file contents]
... [press Enter on empty line]

Option 3: Multi-line input

You: \\
... Please read this project context:
... [paste contents from project_context.md]
... 
[Press Enter on empty line to submit]

Why This Works Better

• ✅ More flexible (can combine context with initial question)
• ✅ Works with any file format
• ✅ Can use template system for preprocessing
• ✅ No new CLI flags needed
• ✅ Context visible in conversation history

Additional Features

For session resumption with context:

• Save sessions with context included (save command)
• Resume with --resume to maintain context across sessions

Closing as completed - functionality exists through template system and multi-line input!
