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 | $0.03234 | $0.03234 |
| Opus 5.5 | $0.01294 | $0.01294 |
| Sonnet 5.5 | $0.00647 | $0.00647 |
| Haiku 4.5 | $0.00323 | $0.00323 |
Grade A, and why
agentic-playwright test-standards.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.

Test Standards
Critical
- Imports: Import
testandexpectfromfixtures/pom/test-options.ts. NEVER from@playwright/testin spec files. - Single-tag rule: Each test has exactly one tag chosen from
@smoke|@sanity|@regression|@e2e|@api|@destructive. NEVER combine tags. NEVER use@functional. NEVER put tags ontest.describe()blocks. @destructiveis the heaviest tag and always wins — but only for shared/global state. A test that mutates state other tests or users depend on (locale, permissions, roles, guest access, feature flags, global settings) is tagged only@destructive. A test that creates and deletes only its own data is isolated, not destructive — tag it by importance (@smoke/@sanity/@regression/@e2e/@api).- Every state-mutating test must have
test.afterEach()ortest.afterAll()cleanup that reverts the change — both@destructiveshared-state tests and isolated tests that write their own data. - Web-first assertions only (
await expect(locator).toBeVisible(),.toHaveText(),.toBeEnabled(),.toHaveCount(...), etc.). NEVERpage.waitForTimeout(...). - Use
test.step()for Given/When/Then structure when a test has more than one distinct phase (setup, action, assertion). - Tests must be independent. No ordering dependencies, no shared mutable state across tests.
- NEVER commit explore-only or debug test files (
.spec.tscontainingconsole.log(await page.content()), temporary probes, etc.). - Static test data is imported from
.tsmodules (test-data/static/**/*.ts) via namedas constexports. NEVER.json. - Dynamic happy-path data comes from Faker factories (
test-data/factories/{area}/); universal type-mismatch arrays fromtest-data/static/util/invalid-values.ts; domain-specific curated sets fromtest-data/static/{area}/*.ts. See thedata-strategyskill. - Page objects are consumed via the fixture (
async ({ appPage }) => ...). NEVERnew PageObject(page)inside a test. - After adding or modifying a test file, run the affected tests and confirm zero failures before finishing the task.
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.

agentic-playwright test-standards.instructions.md is an instructions file published in the GitHub repository idavidov13/agentic-playwright (241 stars, last pushed 3d ago), licensed MIT. It adds 3,234 tokens to every session, about $0.0129 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 2026-08-30.
