agentic-playwright: Instructions file for GitHub Copilot

.github/instructions/enums.instructions.md

agentic-playwright enums.instructions.md is an instructions file for GitHub Copilot from idavidov13/agentic-playwright. It costs 2,598 tokens per session, scanned A, original, MIT.

Rules for storing repeated application values in TypeScript enums, which are named groups of fixed values. It defines naming, file locations, documentation, and how to verify values that mirror messages shown by the application.

In plain words
What is it for?
Use it when adding or changing endpoint paths, roles, storage paths, UI messages, validation text, or other shared application values.
Why use it?
It prevents repeated strings, guessed UI messages, and inconsistent constants from spreading through tests and page objects. It also provides one place to update values used in multiple files.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is idavidov13/agentic-playwright's own configuration. It tells GitHub Copilot how to work on agentic-playwright 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 agentic-playwright configures →

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

agentic-playwright enums.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.

Enums

Critical

  • Convention: TypeScript enum — the scaffold uses the language construct enum, not as const object literals. Stay consistent.
  • Enum name: PascalCase (e.g., Messages, ApiEndpoints, Roles, StorageStatePaths).
  • Enum member: SCREAMING_SNAKE_CASE (e.g., LOGIN_SUCCESS, CURRENT_USER, APP).
  • Location: app-defined strings go in enums/{area}/*.ts; cross-app constants go in enums/util/*.ts. Do not invent a new top-level folder.
  • JSDoc: every enum declaration must have a JSDoc comment describing what the enum groups.
  • No hardcoded repeat strings. Any string used in more than one place — endpoint paths, UI messages, roles, storage-state paths — must live in an enum and be imported.
  • Message values must match the real app. For enums that mirror UI text (error messages, success messages, validation text), the string must be captured via playwright-cli from the live app, not guessed.
  • Edits to existing enum values go through refactor-values. Renaming a key or changing a value cascades through tests, page objects, and schemas.

File Locations

{area} is a placeholder. Before creating or referencing any path below, run ls enums/ to discover the real subdirectory names in this repo (e.g., front-office, back-office) and use those instead.

Type Directory Naming Scaffold examples
App-specific enums enums/{area}/ [name].ts Messages, ApiEndpoints, StorageStatePaths (in enums/app/app.ts)
Shared / utility enums enums/util/ [name].ts Roles (in enums/util/roles.ts)

Instructions

Phase 1: Decide if the value belongs in an enum

Use this decision table. Each row points to the canonical home — use it to prevent enums/ from overlapping with config/ or test-data/static/.

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.
