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

project-factory copilot-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 2mo 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.

What it actually says

Project Factory — Copilot instructions

This repository uses Project Factory, a spec-driven multi-agent delivery framework. Follow it:

  • Read AGENTS.md (repo root) for the operating rules and the lifecycle — it is the canonical, tool-agnostic entry.
  • The full playbook is MASTER-PROMPT.md; the hard gates are checklists/quality-gates.md; the orchestrator is skills/project-factory/SKILL.md.
  • To run it, use the prompt files (Copilot Chat /):
    • /project-factory-init — install the loop into this repo (new project).
    • /project-factory-onboard — retrofit an existing codebase (detect stack, install the loop non-destructively, reverse-engineer requirements + baseline specs).

The deterministic loop (scripts/check-*, OpenSpec specs, gates, evals, trajectory checks, tests) is identical across tools. Copilot lacks Claude Code's parallel subagent fan-out, so run the review-gate / eval / spec passes sequentially with fresh context — the agent that wrote a slice never reviews it (maker ≠ checker). Scripts, gates, specs, and evidence are unchanged. See docs/portability.md.

Changes

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.
