From 9c226ec89806f579b752c5f73625973c8702d148 Mon Sep 17 00:00:00 2001 From: GitHub Actions Date: Fri, 9 Jan 2026 03:53:42 +0000 Subject: [PATCH] Add structured autonomy prompts for generating, implementing, and planning implementation documentation - Introduced `structured-autonomy-generate.prompt.md` for generating implementation plans from PRs. - Added `structured-autonomy-implement.prompt.md` to execute implementation plans step-by-step. - Created `structured-autonomy-plan.prompt.md` for collaborative project planning and outlining development steps. - Implemented prompts for suggesting relevant GitHub Copilot agents, chat modes, collections, instructions, and prompts from the awesome-copilot repository. - Developed `update-implementation-plan.prompt.md` for updating existing implementation plans with new requirements and structured output. --- .github/agents/accessibility.agent.md | 298 +++++++
