scmd Implementation Guide: 3 Must-Borrow Features

Version: 1.0 Date: 2026-01-10 Target Release: Public Launch Estimated Timeline: 4 weeks

Executive Summary

This guide details the implementation of 3 critical features that will bring scmd to feature parity with competitors (sgpt, llm, mods) while maintaining its unique advantages (local-first, command generation, developer focus).

The 3 Features:

  1. Interactive Conversation Mode - Multi-turn conversations with context retention
  2. Beautiful Markdown Output - Syntax highlighting and professional formatting
  3. Template/Pattern System - User-customizable prompts for workflows

Why These 3?

  • Conversation Mode: Table stakes feature - every competitor has this
  • Beautiful Output: First impression matters - makes scmd feel professional
  • Template System: Extensibility without complexity - differentiates from basic tools

Success Metrics:

✅ Users can have 5+ message conversations ✅ Code blocks have syntax highlighting ✅ Users can create and share custom templates ✅ scmd is ready for public launch

Feature 1: Interactive Conversation Mode 🗣️

Borrowed from: sgpt (--repl), llm (conversations), mods (threads)

Why This is Critical

  • Every competitor has this - it's table stakes
  • Users expect to ask follow-up questions
  • Biggest gap in current scmd experience
  • Transforms from "one-shot tool" to "AI pair"
  • Increases user engagement and retention

What to Build

# New commands
scmd chat                           # Start interactive session
scmd chat --continue <id>           # Resume previous conversation
scmd chat --model qwen2.5-7b        # Use specific model
scmd history                        # Show past conversations
scmd history show <id>              # Show specific conversation
scmd history search "docker"        # Search conversations
scmd history delete <id>            # Delete conversation
scmd history clear                  # Clear all history

Database Schema (SQLite)

Create file: ~/.scmd/conversations.db

-- Conversations table
CREATE TABLE conversations (
   id TEXT PRIMARY KEY,           -- UUID
   created_at TIMESTAMP,
   updated_at TIMESTAMP,
   title TEXT,                    -- Auto-generated from first message
   model TEXT,                    -- Model used (e.g., "qwen2.5-1.5b")
   backend TEXT,                  -- Backend used (llamacpp, ollama, etc.)
   metadata JSON                  -- Additional context (tags, folder, etc.)
);


-- Messages table
CREATE TABLE messages (
   id INTEGER PRIMARY KEY AUTOINCREMENT,
   conversation_id TEXT,
   role TEXT,                     -- 'user' or 'assistant'
   content TEXT,
   tokens INTEGER,                -- Token count (for analytics)
   created_at TIMESTAMP,
   FOREIGN KEY (conversation_id) REFERENCES conversations(id) ON DELETE CASCADE
);


-- Indexes for performance
CREATE INDEX idx_conv_updated ON conversations(updated_at DESC);
CREATE INDEX idx_msg_conv ON messages(conversation_id);


-- Full-text search
CREATE VIRTUAL TABLE messages_fts USING fts5(
   conversation_id UNINDEXED,
   content,
   content=messages,
   content_rowid=id
);


-- Triggers to keep FTS in sync
CREATE TRIGGER messages_ai AFTER INSERT ON messages BEGIN
   INSERT INTO messages_fts(rowid, conversation_id, content)
   VALUES (new.id, new.conversation_id, new.content);
END;


CREATE TRIGGER messages_ad AFTER DELETE ON messages BEGIN
   DELETE FROM messages_fts WHERE rowid = old.id;
END;


CREATE TRIGGER messages_au AFTER UPDATE ON messages BEGIN
   UPDATE messages_fts SET content = new.content WHERE rowid = old.id;
END;

Configuration

Add to ~/.scmd/config.yaml:

chat:
 max_context_messages: 20    # Max messages to keep in context
 auto_save: true            # Auto-save after each message
 auto_title: true           # Auto-generate titles from first message

Feature 2: Beautiful Markdown Output with Syntax Highlighting 🎨

Borrowed from: mods (Bubble Tea + Glamour), glow

Why This is Critical

  • Makes scmd feel professional and polished
  • Code snippets need syntax highlighting
  • Markdown is what LLMs output naturally
  • First impression matters for public release
  • Increases readability and user satisfaction

What to Build

Transform plain text output into beautifully formatted, syntax-highlighted markdown with proper styling.

Before:

The code defines a function...
```javascript
function add(a, b) { return a + b; }



**After:** (with colors, formatting, borders, syntax highlighting)

Feature 3: Template/Pattern System 📋

Borrowed from: fabric (patterns), llm (templates)

Why This is Critical

  • Extensibility without plugin complexity
  • Users can customize prompts for their workflows
  • Teams can share templates
  • Differentiates scmd from basic tools
  • Easy to implement, high impact

What to Build

# Create custom templates
scmd template create security-review \
 --prompt "Review this code for security issues..."


# List templates
scmd template list


# Use template
cat auth.js | scmd review --template security-review


# Share templates
scmd template export security-review > template.yaml
scmd template import template.yaml


# Template repositories
scmd template repo add company https://github.com/company/scmd-templates
scmd template search "kubernetes"
scmd template install company/k8s-review

Template Structure

File: ~/.scmd/templates/security-review.yaml

name: security-review
version: "1.0"
author: "security-team"
description: "Security-focused code review with OWASP Top 10 emphasis"
tags:
 - security
 - owasp
 - review


# Can be used with different commands
compatible_commands:
 - review
 - explain


# System prompt (sets AI behavior)
system_prompt: |
 You are a security expert specializing in application security.
 Focus on OWASP Top 10 vulnerabilities and provide actionable remediation.
 Use clear severity ratings: Critical, High, Medium, Low.


# User prompt template (uses Go text/template syntax)
user_prompt_template: |
 Review the following {{.Language}} code for security issues:


 Focus areas:
 1. Injection attacks (SQL, Command, XSS)
 2. Broken authentication
 3. Sensitive data exposure
 4. XML external entities (XXE)
 5. Broken access control
 6. Security misconfiguration
 7. Cross-site scripting (XSS)
 8. Insecure deserialization
 9. Using components with known vulnerabilities
 10. Insufficient logging & monitoring


 Code:
 ```{{.Language}}
 {{.Code}}

{{if .Context}} Additional context: {{.Context}} {{end}}

Provide:

  • Severity rating for each issue
  • Specific vulnerabilities found
  • Remediation steps with code examples
  • Risk assessment

Variables that can be used in template

variables:

  • name: Language description: "Programming language of the code" default: "auto-detect"

  • name: Code description: "The code to review" required: true

  • name: Context description: "Additional context about the codebase" required: false

Output formatting

output: format: markdown sections:

  • title: "Security Assessment" required: true
  • title: "Vulnerabilities Found" required: true
  • title: "Recommendations" required: true

Model recommendations

recommended_models:

  • qwen2.5-7b
  • gpt-4

Examples

examples:

  • description: "Review authentication code" command: "cat login.js | scmd review --template security-review"

  • description: "Review with context" command: "scmd review auth.py --template security-review --context 'Flask app with JWT'"

   }


   var systemPrompt, userPrompt string


   templateName := viper.GetString("template")

       // Use template
       tm, _ := templates.NewTemplateManager()


       data := map[string]interface{}{
           "Code":     code,
           "Language": detectLanguage(file),
           "Context":  viper.GetString("context"),
       }


       systemPrompt, userPrompt, err = tm.Execute(templateName, data)

## Final Notes


### Priority Order


If you need to implement these incrementally:


1. **Conversation Mode** (Week 1) - Most critical, biggest gap
2. **Beautiful Output** (Week 2) - High impact, first impression
3. **Template System** (Week 3) - Differentiator, extensibility


### Quick Wins


Some features can be implemented faster:


- **Progress spinners** - 1 day
- **Basic markdown rendering** - 2 days
- **Simple templates** - 3 days


### Don't Forget


- [ ] Update README with new features
- [ ] Add examples to documentation
- [ ] Create demo GIFs/videos
- [ ] Write release blog post
- [ ] Prepare for Hacker News/Reddit launch


---


**Ready to ship!** These 3 features will make scmd competitive with established tools while maintaining its unique advantages. Good luck with the implementation! 🚀
