pcl copilot-instructions.md

pcl copilot-instructions.md is an instructions file for GitHub Copilot from personamanagmentlayer/pcl. It costs 8,233 tokens per session, scanned A, original, Apache-2.0.

Project guidance for PCL, a TypeScript programming language and compiler for managing AI personas. It covers the compiler, runtime, command-line tools, and built-in persona system.

In plain words
What is it for?
Use it when working on PCL’s lexer, parser, type checking, runtime, standard library, CLI, tests, or persona commands.
Why use it?
It gives a coding agent the project’s architecture and design rules before it changes code, reducing misunderstandings across the compiler and runtime.

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

pcl 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 5d 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.

GitHub Copilot Instructions for PCL (Persona Control Language)

Project Overview

PCL (Persona Control Language) is a domain-specific programming language and compiler for AI persona management. This is a TypeScript-based compiler project that includes:

  • Lexer: Tokenization and scanning
  • Parser: AST generation from tokens
  • Semantic Analysis: Type checking, validation, and symbol resolution
  • Runtime: Execution engine for PCL programs
  • Standard Library: Built-in personas, types, and utilities
  • CLI: Command-line interface for PCL tools

Tech Stack: TypeScript 5.3+, Node.js, ESM modules, Vitest for testing

PCL Bootstrap System

Important: This project includes a PCL-Lite Bootstrap system that enables AI assistants to interpret /persona commands for multi-persona collaboration.

  • Bootstrap File: ../.roadmap/bootstrap/BOOTSTRAP_EN.md
  • Purpose: Embedded runtime v1.0 for AI chat interfaces (ChatGPT, Claude, Gemini, etc.)
  • Personas: 25+ built-in personas (ARCHI, SEC, DEV, DEVOPS, CRITIC, etc.) with specialized skills
  • Commands: 120+ /persona commands for activation, composition, teams, workflows, and more
  • Domain Focus: Standardization personas (STANDARD_ARCHITECT, SPEC_EDITOR, COMPLIANCE_ENGINEER, etc.)

When working on PCL code generation, reference the bootstrap specification to understand the target runtime behavior and persona system that PCL compiles to.

Key Bootstrap Concepts:

  • Persona Activation: /persona [id] - Activate a persona with specialized capabilities
  • Team Composition: /team [id] - Load pre-configured teams (e.g., security-review, dream-team, standardization)
  • Shared Skills: Personas inherit foundation, technical, security, architecture, standards, and tools skills
  • Merge Modes: primary, consensus, weighted, sequential, parallel for multi-persona responses
  • Workflow Orchestration: Define and execute multi-step workflows with persona handoffs

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.
