What it does

Breakdown Feature Implementation is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Prompt for creating detailed feature implementation plans, following Epoch monorepo structure.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Planning and Monorepo tooling. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

When your agent uses it

  • Tasks that involve Planning
  • Tasks that involve Monorepo tooling

Example prompts

  • “/breakdown-feature-implementation”

Requirements

  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit 7cce7cf. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Breakdown Feature Implementation loads about 1.2k tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 398 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Feature Implementation Plan Prompt

Goal

Act as an industry-veteran software engineer responsible for crafting high-touch features for large-scale SaaS companies. Excel at creating detailed technical implementation plans for features based on a Feature PRD. Review the provided context and output a thorough, comprehensive implementation plan. Note: Do NOT write code in output unless it's pseudocode for technical situations.

Output Format

The output should be a complete implementation plan in Markdown format, saved to /docs/ways-of-work/plan/{epic-name}/{feature-name}/implementation-plan.md.

File System

Requirements
  • Detailed feature requirements (bulleted list)
  • Implementation plan specifics
Technical Considerations
System Architecture Overview

Create a comprehensive system architecture diagram using Mermaid that shows how this feature integrates into the overall system. The diagram should include:

  • Frontend Layer: User interface components, state management, and client-side logic
  • API Layer: tRPC endpoints, authentication middleware, input validation, and request routing
  • Business Logic Layer: Service classes, business rules, workflow orchestration, and event handling
  • Data Layer: Database interactions, caching mechanisms, and external API integrations
  • Infrastructure Layer: Docker containers, background services, and deployment components

Use subgraphs to organize these layers clearly. Show the data flow between layers with labeled arrows indicating request/response patterns, data transformations, and event flows. Include any feature-specific components, services, or data structures that are unique to this implementation.

  • Technology Stack Selection: Document choice rationale for each layer
  • Integration Points: Define clear boundaries and communication protocols
  • Deployment Architecture: Docker containerization strategy
  • Scalability Considerations: Horizontal and vertical scaling approaches

Database Schema Design

Create an entity-relationship diagram using Mermaid showing the feature's data model:

  • Table Specifications: Detailed field definitions with types and constraints
  • Indexing Strategy: Performance-critical indexes and their rationale
  • Foreign Key Relationships: Data integrity and referential constraints
  • Database Migration Strategy: Version control and deployment approach
API Design
  • Endpoints with full specifications
  • Request/response formats with TypeScript types
  • Authentication and authorization with Stack Auth
  • Error handling strategies and status codes
  • Rate limiting and caching strategies
