Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is jonlwowski012/copilot-agent-factory's own configuration. It tells GitHub Copilot how to work on copilot-agent-factory itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything copilot-agent-factory configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is [See this doc](../docs/nonexistent.md).

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

copilot-agent-factory documentation.instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Documentation Instructions

Domain: Markdown Documentation (README, guides, examples)
Applies To: README.md, docs/MCP-SERVERS.md, planning artifacts, examples

Documentation Standards

Keep It Concise

  • README.md: Target 900 lines, max 1000 lines
  • Other docs: As long as needed, but favor clarity over verbosity
  • Examples: Short, focused, working code

Examples First

Always show concrete examples before explaining theory:

❌ Don't do this:

## Placeholder System

The placeholder system uses a template-based approach with variable substitution
enabling dynamic content generation through marker replacement...

✅ Do this instead:

## Placeholder System

Templates use `{{placeholder}}` markers that get replaced:

```markdown
**Tech Stack:** {{tech_stack}}

Becomes:

**Tech Stack:** Python 3.10, FastAPI, PyTorch

### Structure for Readability

Use tables, lists, and headings effectively:

**For comparisons:**
| Aspect | Agents | Skills |
|--------|--------|--------|
| Purpose | Role-based experts | Workflow procedures |
| Invocation | `@agent-name` | Auto-activates |

**For steps:**
1. First step
2. Second step
3. Third step

**For categories:**
- **Category 1:** Items with bold labels
- **Category 2:** Items with bold labels

## README.md Structure

Maintain this structure in README.md:

1. **Title & Tagline**
2. **What is this?** (quick overview with bullets)
3. **Quick Start** (3 steps)
4. **Agents vs Skills** (comparison table)
5. **MCP Server Auto-Detection**
6. **Global Instruction Files**
7. **Feature Development Workflow**
8. **Directory Structure**
9. **Available Agent Templates** (46 total)
10. **Available Skills** (7 total)
11. **MCP Server Integrations**
12. **Detection Rules**
13. **Template Placeholders**
14. **Customization**
15. **Best Practices**
16. **Agent Capabilities**
17. **Example Generated Output**

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
