formly-contract: Instructions file for Codex

AGENTS.md

formly-contract AGENTS.md is an instructions file for Codex, OpenCode from dills122/formly-contract. It costs 976 tokens per session, scanned A, original, MIT.

Repository instructions for Formly Contract, a project that turns Angular Formly forms into structured contracts for reliable browser tests and agent queries.

In plain words
What is it for?
Use them when modifying the schema, compiler, workspace, Angular, MCP, or Playwright parts of the repository, especially for contract-first changes.
Why use it?
They keep coding changes within the project's architecture and require evidence, tests, and documentation when behavior or setup changes.

Written for Codex and OpenCode: the file is AGENTS.md.

This is dills122/formly-contract's own configuration. It tells Codex and OpenCode how to work on formly-contract 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 formly-contract 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

formly-contract AGENTS.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.

AGENTS

AI coding guidance for this repository.

Purpose

This repository builds Formly Contract: a compiler, MCP query surface, and Playwright integration for turning Angular Formly forms into reliable agent-readable E2E contracts.

Optimize for:

  • deterministic, versioned semantic contracts with explicit evidence and unknowns
  • reliable typed E2E intent that never depends on model-invented selectors
  • small, explicit changes over broad refactors
  • tests and documentation when behavior, contracts, setup, or commands change

Architecture Boundaries

Primary areas follow ADR 0008:

  • packages/schema/: versioned DTOs, runtime schemas, diagnostics, canonical serialization, and hashing
  • packages/compiler/: form registry, controlled Angular/Formly compilation, and allowlisted projection
  • packages/workspace/: distributed discovery, generation, source indexing, and artifact assembly
  • future packages/angular/: Angular-specific authoring and host integration
  • future packages/mcp/: progressive read-only agent transport
  • future packages/playwright/: validated-plan compilation, reviewed driver registries, and deterministic browser execution

Intent DTOs and validation policy belong in packages/schema/. Do not create apps/mcp-server/, packages/test-intent/, or packages/playwright-driver/; those historical paths were superseded by ADR 0008.

When a change spans areas, preserve ownership boundaries and update shared contracts first.

Contract-First Files

Treat these as interface contracts before implementation details:

  • docs/architecture-overview.md
  • docs/implementation-plan.md
  • the future versioned schemas under packages/schema/

If behavior changes, update the relevant contract and docs in the same change.

Scope Control

  • Keep changes localized to the requested behavior.
  • Avoid unrelated refactors and generated artifact churn.
  • Call out follow-up work separately from the current change.
  • Do not change public interfaces, storage formats, route surfaces, or app names without explicit intent.

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.
