GitHub Copilot custom agents for orchestrating the complete software development lifecycle

Awesome Skills - GitHub Copilot Agents

A collection of specialized GitHub Copilot custom agents for orchestrating the complete software development lifecycle, from requirements gathering through implementation, testing, and review.

Installation

Install via pip:

pip install swe-copilot-agents

Or install from source:

git clone https://github.com/khaerulumam42/agent-generator.git
cd agent-generator
pip install -e .

Overview

This repository contains AI agents that follow the "coordinator and worker" pattern—where specialist agents perform focused work under the guidance of an orchestrator. Each agent has a strong persona, clear boundaries, and specific expertise.

Agents

@dev-orchestrator

Role: Meticulous technical lead who conducts specialist agents like an orchestra conductor

Persona:

• Philosophy: "Right agent, right time, right order"
• Traits: Meticulous, patient, organized, clear
• Metaphor: Orchestra conductor who doesn't play instruments but brings out the best performance from each soloist

Responsibilities:

• Coordinates the complete development lifecycle across 4 movements
• Tracks state obsessively (which movement, which soloist, which outputs)
• Manages review cycles with automatic fix loops (max 2 reviews)
• Seeks human approval at each intermission

Orchestrated Agents:

• @brainstormer (Movement I - Planning)
• @plan-executor (Movement II - Implementation)
• @plan-reviewer (Movement III - Review)
• @pytest-agent (Movement IV - Testing, optional)

Best Practices: ✅ EXCELLENT

• Strong, distinctive persona with musical terminology throughout
• Clear YAML configuration with agents restriction
• Visual workflow diagram (ASCII art)
• Comprehensive error handling and human intervention pathways
• Review cycle feedback loop with automatic fixes
• Memorable tagline: "A great conductor doesn't play every instrument—they know exactly when each section should perform."

@brainstormer

Role: Curious planning agent who asks clarifying questions to crystallize requirements

Persona:

• Philosophy: Uncertainty triggers questions, not assumptions
• Traits: Insatiably curious, thorough, multi-round questioner (1-10 rounds)
• Metaphor: Exploratory researcher who never assumes

Responsibilities:

• Asks 1-10 rounds of clarifying questions before writing plans
• Queries knowledge graph for impact analysis (downstream, cycles, bottlenecks, test seams)
• Creates detailed markdown plan documents in docs/plan/YYYY-MM-DD-*.md
• Integrates knowledge graph findings into every plan

Best Practices: ✅ EXCELLENT

• Strong persona ("insatiably curious")
• Knowledge graph integration for impact analysis
• Multi-round questioning framework with defined stages
• Clear completion criteria (user confirmation before writing plan)
• Comprehensive plan output template with KG analysis sections
• Workflow summary diagram

---

@plan-executor

Role: Senior Python engineer who executes plans by blending seamlessly with existing codebases

Persona:

• Philosophy: "Consistency > Clean Code"
• Traits: Chameleon-like, adaptive, pattern-matching
• Metaphor: Code chameleon who becomes indistinguishable from existing code

Responsibilities:

• Reads 3-5 existing files to understand patterns before writing
• Matches existing style exactly (naming, imports, error handling, formatting)
• Implements requirements from plan documents
• Never "fixes" existing code because it's ugly

Best Practices: ✅ EXCELLENT

• Strong persona with clear philosophy ("Consistency > Clean Code")
• Concrete code examples showing good vs. bad matching
• Specific matching table (naming, imports, errors, strings, formatting)
• Clear boundaries (never "revamp" existing code)
• Executable commands for studying patterns

---

@plan-reviewer

Role: Senior code reviewer and quality assurance engineer who rigorously audits implementation against plans

Persona:

• Philosophy: "Evidence over assumptions"
• Traits: Ruthlessly thorough, evidence-driven, uncompromising
• Metaphor: Auditor who proves everything through code inspection

Responsibilities:

• Extracts all requirements from plan documents
• Searches codebase for concrete evidence of each requirement
• Categorizes execution status (Fully/Partially/Not Executed)
• Performs brittleness analysis via knowledge graph (high centrality, excessive dependencies, deep chains)
• Provides prioritized remediation recommendations

Best Practices: ✅ EXCELLENT

• Strong persona ("ruthlessly thorough")
• Clear execution status definitions with evidence gathering checklist
• Knowledge graph brittleness analysis with risk levels
• Comprehensive report output format
• Priority assignment criteria (P0-P3)
• Status determination rules with specific conditions

---

@pytest-agent

Role: Senior Python QA engineer specializing in pytest with expert-level mocking and patching

Persona:

• Philosophy: "Depth over breadth"
• Traits: Exhaustive, comprehensive, edge-case obsessed
• Metaphor: Test surgeon who operates at every code path

Responsibilities:

• Writes exhaustive test suites (happy path, edge cases, errors, state, integration)
• Expert-level mocking and patching (Mock, MagicMock, patch, PropertyMock)
• Targets >80% coverage for new code
• Tests only newly implemented code (respects scope boundaries)

Best Practices: ✅ EXCELLENT

• Strong persona ("depth over breadth")
• Comprehensive test coverage requirements table
• Expert mocking examples with all patterns
• Clarification protocol for ambiguous behavior
• Clear scope boundaries (only test new code)
• Code style examples (good vs. bad)

---

@knowledge-graph-agent

Role: Expert code analysis specialist who builds knowledge-base graphs from codebases

Persona:

• Philosophy: Static analysis reveals code architecture
• Traits: Multi-lingual, systematic, incremental
• Metaphor: Code cartographer who maps relationships

Responsibilities:

• Scans codebases and generates knowledge-graph.yaml in project root
• Tracks relationships: files, functions, classes, imports, call chains, concerns
• Supports incremental updates (only changed files)
• Version tracking via git commit hashes
• Multi-language support (Python, JS/TS, Go, Java, Rust)

Best Practices: ✅ EXCELLENT

• Clear startup behavior with git hash comparison
• Incremental update mode to avoid full rescans
• Comprehensive YAML output format specification
• Complete analysis standards with good/bad examples
• Web framework pattern recognition (Flask, FastAPI, Express, Gin)
• Validation checklist before completion

Review Cycle Logic

1. Review #1 identifies issues → If major issues found, trigger fix cycle
2. Fix Cycle (@plan-executor) implements recommendations
3. Review #2 (FINAL) re-audits → If issues persist, human intervention required
4. Maximum 2 reviews enforced

Agent File Structure

All agents follow this structure:

---
name: agent-name
description: Brief description of purpose
tools: ["tool1", "tool2"]
agents: ["agent1", "agent2"]  # For orchestrators only
target: vscode | github-copilot
---

# Persona description
## Core Philosophy
## Your Role
## [Specific sections per agent]
## Boundaries (Always Do / Ask First / Never Do)
## Commands

---

Contributing

When adding new agents:

1. Follow the persona pattern - Give each agent a distinctive personality
2. Define clear boundaries - What they always do, ask first, never do
3. Include executable commands - Concrete bash commands they can run
4. Provide examples - Good vs. bad outputs
5. Add visual workflow - ASCII diagrams for complex agents
6. Document best practices - Mark if agent follows Copilot best practices
