Potential Duplicates

Group 1: C#/.NET Janitor vs .NET Upgrade — Identical Descriptions

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/csharp-dotnet-janitor.agent.md	Agent	Perform janitorial tasks on C#/.NET code including cleanup, modernization, and tech debt remediation.
agents/dotnet-upgrade.agent.md	Agent	Perform janitorial tasks on C#/.NET code including cleanup, modernization, and tech debt remediation.

Why flagged: Both agents share a word-for-word identical description. Their names differ (C#/.NET Janitor vs .NET Upgrade), and content inspection shows both target the same C#/.NET cleanup/modernization workflow, making one potentially redundant.

---

Group 2: Implementation Plan Generation Agents (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/planner.agent.md	Agent	Generate an implementation plan for new features or refactoring existing code.
agents/implementation-plan.agent.md	Agent	Generate an implementation plan for new features or refactoring existing code.
agents/plan.agent.md	Agent	Strategic planning and architecture assistant focused on thoughtful analysis before implementation.
agents/task-planner.agent.md	Agent	Task planner for creating actionable implementation plans

Why flagged: planner.agent.md and implementation-plan.agent.md share an identical description. plan.agent.md and task-planner.agent.md cover substantially the same planning territory. All four agents produce implementation plans for code changes.

---

Group 3: Gilfoyle Code Review — Agent + Instruction

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/gilfoyle.agent.md	Agent	Code review and analysis with the sardonic wit and technical elitism of Bertram Gilfoyle from Silicon Valley.
instructions/gilfoyle-code-review.instructions.md	Instruction	Gilfoyle-style code review instructions that channel the sardonic technical supremacy of Silicon Valley's most arrogant systems architect.

Why flagged: Both resources implement the same Gilfoyle persona for code review. The agent performs active review sessions; the instruction passively applies the same Gilfoyle code-review style. Cross-type overlap with identical persona, identical domain.

---

Group 4: PRD Agent + Skill

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/prd.agent.md	Agent	Generate a comprehensive Product Requirements Document (PRD) in Markdown, detailing user stories, acceptance criteria, technical considerations, and metrics.
skills/prd/SKILL.md	Skill	Generate high-quality Product Requirements Documents (PRDs) for software systems and AI-powered features. Includes executive summaries, user stories, technical specifications, and risk analysis.

Why flagged: Both share the same name (prd) and serve the same purpose — generating PRD documents with user stories and acceptance criteria. Cross-type overlap where one may make the other redundant.

---

Group 5: Markdown Accessibility — Agent + Instruction (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/markdown-accessibility-assistant.agent.md	Agent	Improves the accessibility of markdown files using five GitHub best practices
instructions/markdown-accessibility.instructions.md	Instruction	Markdown accessibility guidelines based on GitHub's 5 best practices for inclusive documentation

Why flagged: Both explicitly reference the same source material (GitHub's 5 best practices for markdown accessibility) and serve the same purpose. Cross-type overlap where the agent and instruction may make each other redundant.

---

Group 6: MS-SQL DBA — Agent + Instruction (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/ms-sql-dba.agent.md	Agent	Work with Microsoft SQL Server databases using the MS SQL extension.
instructions/ms-sql-dba.instructions.md	Instruction	Instructions for customizing GitHub Copilot behavior for MS-SQL DBA chat mode.

Why flagged: Same topic (MS-SQL DBA), near-identical scope. The instruction explicitly states it provides guidelines when "the ms-sql-dba.agent.md chat mode is active" — effectively making the instruction a companion to the agent with heavily overlapping content.

---

Group 7: Context7 — Agent + Instruction (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/context7.agent.md	Agent	Expert in latest library versions, best practices, and correct syntax using up-to-date documentation
instructions/context7.instructions.md	Instruction	Use Context7 for authoritative external docs and API references when local context is insufficient

Why flagged: Both exist to bring Context7 MCP documentation into Copilot interactions. The agent is an active expert assistant; the instruction passively directs Copilot to use Context7. May overlap or serve as redundant coverage of the same integration.

---

Group 8: Beast Mode Coding Agents — Multiple Variants

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/4.1-Beast.agent.md	Agent	GPT 4.1 as a top-notch coding agent.
agents/Thinking-Beast-Mode.agent.md	Agent	A transcendent coding agent with quantum cognitive architecture, adversarial intelligence, and unrestricted creative freedom.
agents/Ultimate-Transparent-Thinking-Beast-Mode.agent.md	Agent	Ultimate Transparent Thinking Beast Mode
agents/gpt-5-beast-mode.agent.md	Agent	Beast Mode 2.0: A powerful autonomous agent tuned specifically for GPT-5.
agents/voidbeast-gpt41enhanced.agent.md	Agent	Advanced autonomous developer agent for elite full-stack development with multi-mode capabilities.

Why flagged: Five variants of "beast mode" autonomous coding agent all targeting the same use case (powerful, unrestricted full-stack development). While some target different models (GPT-4.1, GPT-5), the core purpose and behavior are essentially identical. The proliferation of near-identical agents may confuse users.

Groups 11–20 (additional duplicate candidates)

Group 11: Playwright Browser Testing — Two Agents

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/playwright-tester.agent.md	Agent	Testing mode for Playwright tests
agents/gem-browser-tester.agent.md	Agent	E2E browser testing, UI/UX validation, visual regression, Playwright automation.

Why flagged: Both agents target Playwright-based browser/E2E testing. gem-browser-tester is broader (adds UI/UX validation and visual regression), but both are primarily Playwright test agents with overlapping scope.

---

Group 12: Prompt Engineering — Two Agents + Skill

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/prompt-builder.agent.md	Agent	Expert prompt engineering and validation system for creating high-quality prompts
agents/prompt-engineer.agent.md	Agent	A specialized chat mode for analyzing and improving prompts. Every user input is treated as a prompt to be improved.
skills/prompt-builder/SKILL.md	Skill	Guide users through creating high-quality GitHub Copilot prompts with proper structure, tools, and best practices.

Why flagged: All three resources target prompt creation and improvement. prompt-builder agent and prompt-builder skill share the same name and purpose. prompt-engineer describes the same core workflow (analyzing/improving prompts) with only minor framing differences.

---

Group 13: Suggest Awesome Copilot Resources — Three Near-Identical Skills (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
skills/suggest-awesome-github-copilot-agents/SKILL.md	Skill	Suggest relevant GitHub Copilot Custom Agents files from the awesome-copilot repository based on current repository context and chat history
skills/suggest-awesome-github-copilot-instructions/SKILL.md	Skill	Suggest relevant GitHub Copilot instruction files from the awesome-copilot repository based on current repository context and chat history
skills/suggest-awesome-github-copilot-skills/SKILL.md	Skill	Suggest relevant GitHub Copilot skills from the awesome-copilot repository based on current repository context and chat history

Why flagged: Three skills with nearly identical structure, purpose, and wording — differing only in resource type (agents vs instructions vs skills). Could potentially be a single parameterized skill.

---

Group 14: Mentor / Mentoring Resources (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/mentor.agent.md	Agent	Help mentor the engineer by providing guidance and support.
agents/mentoring-juniors.agent.md	Agent	Socratic mentor for junior developers. Guides through questions, never gives direct answers.
skills/mentoring-juniors/SKILL.md	Skill	Socratic mentoring for junior developers and AI newcomers. Guides through questions, never answers.

Why flagged: mentoring-juniors.agent.md and skills/mentoring-juniors appear to package identical content as both an agent and a skill (same description, same Socratic framing). mentor.agent.md overlaps in domain (engineering guidance/mentoring), though it targets a broader audience.

---

Group 15: Technical Documentation Writing — Two Agents + Skill

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/se-technical-writer.agent.md	Agent	Technical writing specialist for creating developer documentation, technical blogs, tutorials, and educational content
agents/gem-documentation-writer.agent.md	Agent	Generates technical documentation, README files, API docs, diagrams, and walkthroughs.
skills/documentation-writer/SKILL.md	Skill	Diátaxis Documentation Expert. An expert technical writer specializing in creating high-quality software documentation.

Why flagged: All three target technical documentation creation for software projects. The two agents and the skill cover the same core workflow (writing technical docs, READMEs, API docs) with similar audiences, though documentation-writer skill applies the Diátaxis framework as a differentiator.

---

Group 16: Security Code Review — Multiple Agents

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/se-security-reviewer.agent.md	Agent	Security-focused code review specialist with OWASP Top 10, Zero Trust, LLM security, and enterprise security standards
agents/wg-code-sentinel.agent.md	Agent	Ask WG Code Sentinel to review your code for security issues.
agents/gem-reviewer.agent.md	Agent	Security auditing, code review, OWASP scanning, secrets/PII detection, PRD compliance verification.

Why flagged: Three agents all performing security-focused code review with OWASP coverage. gem-reviewer also does PRD compliance (broader), and wg-code-sentinel has a distinct JARVIS-style persona, but the core security review function overlaps significantly across all three.

---

Group 17: Agent Governance + Safety — Agent + Instruction (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/agent-governance-reviewer.agent.md	Agent	AI agent governance expert that reviews code for safety issues, missing governance controls, and helps implement policy enforcement, trust scoring, and audit trails in agent systems.
instructions/agent-safety.instructions.md	Instruction	Guidelines for building safe, governed AI agent systems. Apply when writing code that uses agent frameworks, tool-calling LLMs, or multi-agent orchestration to ensure proper safety boundaries, policy enforcement, and auditability.

Why flagged: Both target AI agent safety and governance. The agent performs active reviews; the instruction applies the same principles passively. Overlapping domain and audience with similar recommendations.

---

Group 18: GitHub Actions Expert + Instruction (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/github-actions-expert.agent.md	Agent	GitHub Actions specialist focused on secure CI/CD workflows, action pinning, OIDC authentication, permissions least privilege, and supply-chain security
instructions/github-actions-ci-cd-best-practices.instructions.md	Instruction	Comprehensive guide for building robust, secure, and efficient CI/CD pipelines using GitHub Actions.

Why flagged: Agent and instruction both cover GitHub Actions CI/CD best practices, including security hardening (OIDC, permissions). Cross-type overlap — the instruction codifies what the agent would advise.

---

Group 19: Bicep Plan/Implement vs Terraform Azure Plan/Implement (previously flagged — see #1076)

• Reviewed — these are intentionally separate

Resource	Type	Description
agents/bicep-plan.agent.md	Agent	Act as implementation planner for your Azure Bicep Infrastructure as Code task.
agents/bicep-implement.agent.md	Agent	Act as an Azure Bicep Infrastructure as Code coding specialist that creates Bicep templates.
agents/terraform-azure-planning.agent.md	Agent	Act as implementation planner for your Azure Terraform Infrastructure as Code task.
agents/terraform-azure-implement.agent.md	Agent	Act as an Azure Terraform Infrastructure as Code coding specialist that creates and reviews Terraform for Azure resources.

Why flagged: Two structurally identical plan/implement pairs — one for Bicep, one for Terraform. bicep-plan and terraform-azure-planning have near-identical descriptions (only tool name differs); same for the implement pair.
