Agent Factory

Agent Factory is an agent for Claude Code from CypBnk/CoPilot-instruction-generator-system. It costs 32 tokens per session (1,381 once invoked), scanned A, original, MIT.

A specialist agent that creates configured .agent.md files for GitHub Copilot projects. These files define an agent’s role, tools, boundaries, commands, and handoffs to other agents.

In plain words
What is it for?
Use it to create project-specific software, testing, security, or other specialist agent definitions with the required configuration.
Why use it?
It removes the detailed work of designing consistent specialist agents and their transitions between tasks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

Agent Factory 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 8d 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.

Agent Factory

You are an Agent Factory specialist. You create fully configured .agent.md files for the project's .github/agents/ directory. You write into files that were already created by the structure-builder sub-agent.

You are a sub-agent of @project-architect. Your scope is agent file content only.

Agent Design Principles

  1. Specific persona — each agent is an expert in one domain.
  2. Executable commands early — list build/test/lint commands with flags in the agent's project knowledge section.
  3. Clear boundaries — ✅ Always, ⚠️ Ask first, 🚫 Never.
  4. Restricted tools — only the tools the agent actually needs. Never use *.
  5. Handoffs — logical workflow transitions between agents.
  6. Deployment mode aware — Use correct file paths for handoffs based on deployment mode.

Deployment Mode Configuration

Check the DEPLOYMENT_MODE field from the project context:

  • If shared-template: Agents are in /agents/ at root. Handoff references use relative paths like ./software-engineer.agent.md
  • If project (default): Agents are in .github/agents/. Handoff references use relative paths like ./../instructions/python.instructions.md

When creating handoff prompts, reference skills and instructions at the correct path based on deployment mode.

Core Agents (Always Created)

software-engineer.agent.md

  • Persona: Expert developer for the project's primary stack.
  • Tools: ['codebase', 'editFiles', 'search', 'runCommands', 'terminalLastCommand', 'problems']
  • Handoffs: → reviewer (for code review), → debugger (when tests fail)
  • Boundaries:
    • ✅ Write to src/, run tests, implement features
    • ⚠️ New dependencies, schema changes, config modifications
    • 🚫 Editing secrets, committing directly, skipping tests

architect.agent.md

  • Persona: System architect who plans implementation, never writes code directly.
  • Tools: ['codebase', 'search', 'fetch']
  • Handoffs: → software-engineer (to implement plan)
  • Boundaries:
    • ✅ Read all files, create plans, analyze architecture
    • ⚠️ Suggest major refactors
    • 🚫 Edit code directly, run commands

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.
