+description: Generate or update workspace instructions file for AI coding agents
+argument-hint: Optionally specify a focus area or pattern to document for agents
+agent: agent
+---
+Related skill: `agent-customization`.
+
+Generate or update workspace instructions (`.github/copilot-instructions.md` as first choice, or `AGENTS.md` if it is already present) for guiding AI coding agents in this workspace.
+
+## Discovery
+
+Search for existing AI conventions using this glob pattern: `**/{.github/copilot-instructions.md,AGENT.md,AGENTS.md,CLAUDE.md,.cursorrules,.windsurfrules,.clinerules,.cursor/rules/**,.windsurf/rules/**,.clinerules/**,README.md}`
+
+Then, start a subagent to research essential knowledge that helps an AI agent be immediately productive. Only include sections the workspace benefits from—skip any that don't apply:
+
+```markdown
+# Project Guidelines
+
+## Code Style
+{Language and formatting preferences - reference key files that exemplify patterns}
+
+## Architecture
+{Major components, service boundaries, data flows, the "why" behind structural decisions}
+
+## Build and Test
+{Commands to install, build, test - agents will attempt to run these automatically}
+
+## Project Conventions
+{Patterns that differ from common practices - include specific examples from the codebase}
+
+## Integration Points
+{External dependencies and cross-component communication}
+
+## Security
+{Sensitive areas and auth patterns}
+```
+
+## Guidelines
+
+- If `.github/copilot-instructions.md`/`AGENTS.md` exists, merge intelligently—preserve valuable content while updating outdated sections
+- If `AGENTS.md` exists, prefer updating it; for monorepos, use nested files per package (closest file to edited code wins)
+- Write concise, actionable instructions (~20-50 lines) using markdown structure
+- Link specific examples from the codebase when describing patterns
+- Reference key files/directories that exemplify important patterns
+- Avoid generic advice ("write tests", "handle errors")—focus on THIS project's specific approaches
+- Document only discoverable patterns, not aspirational practices
+- List build/test commands explicitly—agents will attempt to run them automatically
+
+Update `.github/copilot-instructions.md`/`AGENTS.md`, then ask for feedback on unclear or incomplete sections to iterate.
