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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.04004 | $0.04004 |
| Opus 5.5 | $0.01602 | $0.01602 |
| Sonnet 5.5 | $0.00801 | $0.00801 |
| Haiku 4.5 | $0.00400 | $0.00400 |
Grade A, and why
tcoe-playwright-example 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 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.

Copilot Instructions for HMCTS Playwright Template
Architecture Overview
This is an HMCTS Playwright test automation template following Page Object Model (POM) with hierarchical component structure:
- Base class (
playwright-e2e/page-objects/base.ts) - Provides common components to all pages via composition - Components (
playwright-e2e/page-objects/components/) - Reusable UI sections (headers, case lists) shared across pages - Pages (
playwright-e2e/page-objects/pages/) - Full page implementations extendingBase - Fixtures (
playwright-e2e/fixtures.ts) - Dependency injection system for pages and utilities - Utils (
playwright-e2e/utils/) - Focused utility classes (validators, config, cookie handlers)
Key Patterns & Conventions
Test Organization
- Tests tagged for selective execution:
@a11y,@performance,@visual,@smoke,@exui,@cui - Global setup/teardown (
global.setup.ts,global.teardown.ts) handles authentication and session management - Performance tests require
@performancetag ANDlighthousePagefixture (chromium only) - Always import from centralized fixtures:
import { test, expect } from "../fixtures"(never from@playwright/test)
Fixture-Based Dependency Injection
// Fixtures provide pre-configured page objects and utilities
test("example", async ({ exuiCaseListPage, axeUtils, config, idamPage }) => {
// All dependencies injected automatically - no manual instantiation
await exuiCaseListPage.goto();
await axeUtils.audit();
});
User & Session Management
- Global setup creates sessions for user roles (caseManager, judge) stored in
.sessions/ - Use
test.use({ storageState: config.users.caseManager.sessionFile })to select session - Dynamic citizen users:
await citizenUserUtils.createUser()returns ephemeral credentials - IDAM tokens via
idamUtils.generateIdamToken()for API operations - Session validation:
SessionUtils.isSessionValid(sessionFile, cookieName)avoids re-authentication
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.

tcoe-playwright-example copilot-instructions.md is an instructions file published in the GitHub repository hmcts/tcoe-playwright-example (9 stars, last pushed 2d ago), licensed MIT. It adds 4,004 tokens to every session, about $0.0160 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
