terradart: Instructions file for Codex

AGENTS.md

terradart AGENTS.md is an instructions file for Codex, OpenCode from nozomi-koborinai/terradart. It costs 8,676 tokens per session, scanned C, original, Apache-2.0.

An AGENTS.md instruction file for TerraDart, a project that maintains a catalog of Google Terraform provider resources. It describes the current maintenance phase, scheduled automation, release process, and areas of maintainer focus.

In plain words
What is it for?
Working on TerraDart's catalog, scheduled schema bumps, wave releases, loop-health checks, and the path toward beta validation.
Why use it?
It tells coding agents how schema updates, weekly releases, health checks, and validation gates fit together. This helps changes follow the project's current operating process.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is nozomi-koborinai/terradart's own configuration. It tells Codex and OpenCode how to work on terradart 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 terradart configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is --output ../terradart_google/lib/src \.

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 C, and why

terradart AGENTS.md scanned grade C with 2 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 3d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

Agent Guide

This file is the shared source of truth for coding agents working on TerraDart. Tool-specific files such as CLAUDE.md or .cursor/rules/* should point back here instead of duplicating policy.

Current phase — maintenance + path to beta

The GA hashicorp/google catalog is filled (alpha). The curation push is over; the harness runs in maintenance mode:

Loop Cadence Actor → merge path
Schema bump (GA + google-beta ride-along) Sundays 22:00 UTC (schema-bump.yml) Monday-morning agent (runbook) → bump-merge.yml executor, gated by BUMP_MERGE_ENABLED
Wave shipping Weekly, Tuesday mornings (Cursor schedule); no-op while tool/curation_backlog.yaml is empty agent (runbook) → wave-open.yml + wave-merge.yml executor, gated by WAVE_MERGE_ENABLED
Loop health Mondays 03:00 UTC (loop-health.yml) report appended to the loop-health issue

Human / maintainer focus in this phase:

  • Path to beta — three external-validation gates; the canonical list lives in status (not duplicated here).
  • Example-debt paydown — the 2026-08 apply-excluded batch left a large tool/example_debt.yaml; shrinking it is standing quality work via terradart-backfill-examples.
  • Cookbook and docs — real-apply records and user-facing guides.

google-beta support is a filled beta-only catalog (128 resource factories at the current provider pin): packages/terradart_google_beta. Types that also exist in GA stay in terradart_google. There is still no backlog sweep or wave lane for new names — a later provider pin that adds a beta-only type lands on request via terradart-add-beta-resource. Generated against a filtered schema fixture (source_beta/, re-extracted automatically by the weekly schema bump at the GA bump version via extract_schema_subset.dart --resources-from, and by hand only when the curated set changes — never hand-edited; schema.json keys are the single source of truth for the set). Universal QA Gate 9 fails the build if a beta-only type appears in the GA schema — promotion means demoting the factory from beta (breaking, maintainer work) while GA curation goes through the backlog. Per-provider pipeline coordinates live in tool/providers.yaml; beta wrappers pin the provider meta-argument (wrap --resource-provider) because beta shares the GA google_* type prefix. Beta examples are synth + terraform validate only (the apply-smoke skip ledger records why). The package releases in lockstep and publishes as publish.yml Phase 4 — its FIRST pub.dev release must be a manual maintainer dart pub publish (OIDC automated publishing only covers packages that already exist there).

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.
