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 5.1 | $0.01899 | $0.01899 |
| Opus 5.5 | $0.00760 | $0.00760 |
| Sonnet 5.5 | $0.00380 | $0.00380 |
| Haiku 4.5 | $0.00190 | $0.00190 |
Grade A, and why
webjs 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.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Copilot Instructions: webjs app
You are working on a webjs app, an AI-first, no-build, web-components-first framework. Read AGENTS.md for the full API reference and CONVENTIONS.md for project-specific conventions. When AGENTS.md doesn't cover what you need, the full hosted docs are at https://webjs.dev/docs.
Persistence + scaffold rules (non-negotiable)
- Use Drizzle + SQLite for data, never JSON files. It's already wired up
(
db/schema.server.ts,db/connection.server.ts,npm run db:generate+npm run db:migrate). For ANY data the app stores (todos, posts, messages, products, comments…), define a Drizzle table. NEVER createdata/*.json,db.json, or any JSON file as a fake database. NEVER use module-scope arrays / Maps as a substitute. NEVER use localStorage for app data. It resets on reload and cannot scale. This is a project convention (CONVENTIONS.md). - The scaffold is reference, not the final product. Replace
app/page.ts, the exampleUsermodel, the example users module, etc. with the app the user actually asked for. Don't ship "Hello from " as the deliverable. - Only two templates exist:
webjs create <name>(default full-stack) and--template api. The CLI rejects any other--templatevalue. Pick:- Any product UI (todo, blog, dashboard, marketplace, social, a SaaS with accounts…) → default
- HTTP/JSON API only, no UI →
--template api - Auth (login, session, a protected route) ships as a full-stack gallery card, not a template.
Before starting ANY work
FIRST, before writing any code:
- Check
git branch --show-current.- If on main/master: create a feature branch before editing.
- If on a feature branch: verify it matches the task at hand.
- Sync:
git fetch origin && git rebase origin/mainif behind.
Autonomous mode (sandbox / no-prompt)
If running without interactive approval (sandbox, auto-approve, etc.):
- On main? Auto-create feature/ branch
- Parent behind? Auto-rebase. Merge? Auto-merge + delete feature branches.
- Auto-generate meaningful commit messages. Fix tests and violations.
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.
