Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.05109 | $0.05109 |
| Opus 5 | $0.02554 | $0.02554 |
| Sonnet 5 | $0.01022 | $0.01022 |
| Haiku 4.5 | $0.00511 | $0.00511 |
Grade A, and why
agentic-playwright common-tasks.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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 438 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Prompt Templates for Agentic Playwright
Codegen sub-router. Owns prompt templates per artifact type and the post-generation verification checklist. Plugs into ai-native-workflow Phase 2 (Route) for codegen intents.
For the 8-phase workflow see ai-native-workflow/SKILL.md. For worked examples and troubleshooting see this skill's references/.
Critical
These rules are unique to template usage. All other rules (selectors, waits, types, Zod strictness, response validation, tags, fixtures, JSDoc, no-XPath, no-hardcoded-strings, etc.) live in the Constitution (the always-loaded MUST/SHOULD/WON'T tables wrapping these instructions) and the leaf skills (api-testing, page-objects, selectors, test-standards, data-strategy, type-safety, fixtures, enums). Re-read the Constitution + the matching leaf skill's Critical block before generating from any template here.
- Resolve
{area}first. Every template contains{area}as a placeholder. Run the matchingls(ls pages/,ls tests/,ls fixtures/api/schemas/,ls test-data/factories/,ls test-data/static/,ls enums/) and substitute the real folder name before filling the template. Do not guess. - Templates are starters, not substitutes. Each template is a 10-15 line scaffold. The leaf skill listed for the category owns the deep rules — load it and follow it end-to-end. Never reimplement a leaf skill's rules inline in your prompt.
- Walk the verification checklist (below) after generating. It is the canonical post-codegen audit; the leaf skills point here for it.
Instructions
Phase 1: Identify the task category and resolve paths
Match the user's request to one row, then run the ls commands the row's templates need.
| Category | Template section | Specialized skill(s) | ls to run before filling |
|---|---|---|---|
| Page object / component | Page Object Tasks | page-objects, selectors, playwright-cli |
ls pages/ |
| Functional / E2E test | Test Tasks | test-standards, data-strategy |
ls tests/, ls test-data/factories/ |
| API test | Test Tasks → Add API Test | api-testing, test-standards |
ls tests/, ls fixtures/api/schemas/, ls enums/ |
| Zod response schema | API Schema Tasks | api-testing, type-safety |
ls fixtures/api/schemas/ |
| Data factory | Data Factory Tasks | data-strategy, type-safety |
ls test-data/factories/ |
| Static test data | Data Factory Tasks → Static Test Data | data-strategy, api-testing |
ls test-data/static/ |
| Fixture (POM / helper) | Fixture Tasks | fixtures, helpers |
(no path placeholder) |
| UI component | Component Tasks | page-objects, selectors |

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 common-tasks.instructions.md is an instructions file published in the GitHub repository idavidov13/agentic-playwright (139 stars, last pushed 6d ago), licensed MIT. It adds 5,109 tokens to every session, about $0.0255 per session on Opus 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.
