Use this skill to research and design an agent before building it. Reads project documents, identifies agents, researches MCS components, scores architecture, writes instructions, and generates eval sets. Use after /mcs-init, when documents change, when the user wants to analyze requirements, or when brief.json needs enrichment.

Create custom agent capabilities when discovering novel tools, receiving task-agnostic tips from reviewers, or after researching specialized workflows not covered in existing instructions. Teaches structure, YAML optimization for LLM discoverability, and token efficiency.

'Generates PR reference XML containing commit history and unified diffs between branches with extension and path filtering. Includes utilities to list changed files by type and read diff chunks. Use when creating pull request descriptions, preparing code reviews, analyzing branch changes, discovering work items from diffs, or generating structured diff summaries. - Brought to you by microsoft/hve-core'

C# coding standards and conventions for DataFactory.MCP. Use when writing or reviewing C# code.

Implementation finalization with PR. Use when implementation is complete and you need to commit, push, or open a pull request. Includes automated reviews and technical debt tracking. Do not use during implementation (use devsquad.implement), for standalone intermediate commits (use git-commit), or for branch creation (use git-branch).

Multi-perspective code review for a branch before merging. Use when: reviewing a branch, preparing a PR, pre-merge review, auditing a feature branch, or when /branch-review is invoked. Spawns three constructive reviewer subagents (correctness, security, usability), then runs an adversarial gap analysis to find what they missed, and synthesizes all findings into a unified review report.

Summarizes the results of a GitHub search query in a human friendly markdown table that is easy to read and understand. ALWAYS use this skill when displaying the results of a GitHub search query.

Use when about to orchestrate a subagent-driven-development execute-plan session — provides 5 realistic task scenarios with Amplifier delegate() patterns, model_role selection, status handling (DONE, DONE_WITH_CONCERNS, NEEDS_CONTEXT), and fix loops for spec and quality issues

Generate a branded HTML impact report showing what GitHub Copilot helped you accomplish — goals delivered, human effort equivalent, skills augmented, collaboration patterns, and estimation evidence grounded in peer-reviewed research. Works with any Copilot CLI or VS Code agent session.

Review an implementation plan produced by the Plan agent. It is CRITICAL to review plans before handing off to implementation — plans often have gaps, incorrect assumptions, or suboptimal sequencing that are cheaper to catch now than after coding. Use when the user asks to 'review the plan', 'check my plan', 'is this plan ready', or after the Plan agent produces a plan.md.

Monitor a pull request until CI status or Copilot review is available. Use when: monitor PR, watch PR, land PR, wait for CI, wait for checks, wait for review, check PR status. Starts two async terminal tasks (CI + Copilot review) and reacts when either completes.

Reviewer rejection workflow and strict lockout semantics

End-to-end review, fix, publish, and verify a blog post PR from another author

'Review VS Code release notes for style, structure, and completeness. Use for reviewing Insiders or Stable release notes against writing guidelines. Produces an actionable list of recommendations.'

Environment manager-specific discovery patterns and known issues. Use when working on or reviewing environment discovery code for conda, poetry, pipenv, pyenv, or venv.

Create standardized git commits with Conventional Commits. Use when the user asks to commit changes, generate a commit message, or at the end of an implementation. Analyzes the actual diff to determine type, scope, and message. Supports logical file grouping and work item references (GitHub Issues and Azure DevOps). Do not use for branch creation (use git-branch), push, or pull requests (use pull-request).

List and review Advanced Security alerts for an Azure DevOps repository. Shows dependency vulnerabilities, secret exposure, and code scanning findings with filtering by severity, state, and alert type.

Use when composing, writing, drafting, or reviewing a PR title, PR description, or PR body in Fluid Framework — provides title style, body template, and section guidance.

'Create a hook (.json) to enforce policy or automate agent lifecycle events.'

Review a PR for correctness, pattern compliance, testing, accessibility, and safety. Produces a confidence score for merge readiness.

Multi-model council review for diffs, pull requests, and risky changes. It is CRITICAL to use this skill after ANY non-trivial development phase — changes are usually not 100% correct. Development CANNOT be called done until the code has been reviewed. Use whenever the user asks for a review, PR feedback, a bug hunt in recent edits, or wants multiple models to inspect the same change independently. Also use when the user asks to 'discuss findings', 'cross-review', or 'debate' review results between models.

Generates eval test cases from an eval suite plan (output of /eval-suite-planner) or a plain-English agent description. Supports both single-response and conversation (multi-turn) evaluation modes. Outputs a Copilot Studio test set table, a CSV file for import (single-response only), and a docx report for human review.

'**WORKFLOW SKILL** — Create, update, review, fix, or debug VS Code agent customization files (.instructions.md, .prompt.md, .agent.md, SKILL.md, copilot-instructions.md, AGENTS.md). USE FOR: saving coding preferences; troubleshooting why instructions/skills/agents are ignored or not invoked; configuring applyTo patterns; defining tool restrictions; creating custom agent modes or specialized workflows; packaging domain knowledge; fixing YAML frontmatter syntax. DO NOT USE FOR: general coding questions (use default agent); runtime debugging or error diagnosis; MCP server configuration (use MCP docs directly); VS Code extension development. INVOKES: file system tools (read/write customization files), ask-questions tool (interview user for requirements), subagents for codebase exploration. FOR SINGLE OPERATIONS: For quick YAML frontmatter fixes or creating a single file from a known pattern, edit the file directly — no skill needed.'

'Check OPA Rego version compatibility for rego-cpp. Use when: updating OPA version, checking for new OPA releases, auditing rego-cpp compatibility, planning OPA upgrade work, reviewing OPA release notes for rego-cpp impact. Fetches OPA release notes, compares with current rego-cpp support, and produces an actionable compatibility report.'

Prepare an external contributor's PR for maintainer review by redirecting it into a dedicated review branch, then merging and creating a new finalization PR targeting next. Use when triaging/reviewing contributor PRs, merging external PRs with maintainer changes, or setting up a review workflow for incoming community contributions.

Systematic debugging with structured triage. Use when tests fail, builds break, runtime behavior does not match expectations, or any unexpected error occurs during implementation. Do not use for planned refactoring (use code review), for test strategy (use implement agent's TDD flow), or for security-specific issues (use security-review).

Use when asked to review code, review a branch, or do a code review. Spawns Breaker (correctness) and API Analyst (compatibility/conventions) sub-agents while the orchestrator reviews architecture, tests, performance, and security.

Forms a GitHub search query based on a natural language query and the type of search (issue or PR). This skill helps users create effective search queries to find relevant issues or pull requests on GitHub.
