What is nowline AGENTS.md?

A set of repository instructions for Nowline, a text-based language and toolchain for product and engineering roadmaps. It explains the project, where its public-source boundary lies, and what agents must check before changing core files.

Use it when working on Nowline’s grammar, parser, validator, printer, release publishing, or repository automation.

It helps coding agents avoid violating the repository’s rules, especially rules about reading the language specifications and not connecting the open-source project to prohibited private services.

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.

Model	Per session	Once invoked
Fable 5	$0.03258	$0.03258
Opus 5	$0.01629	$0.01629
Sonnet 5	$0.00652	$0.00652
Haiku 4.5	$0.00326	$0.00326

Security

Grade A, and why

nowline 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 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Orientation for AI coding agents (Cursor, Claude Code, OpenAI Codex CLI, Aider) working in this repo. Human contributors should start with README.md and CONTRIBUTING.md — this file deliberately does not duplicate them.

What this repo is

Nowline is a text-first DSL for product/engineering roadmaps, plus the toolchain that parses, validates, lays out, and renders it. The .nowline file is the product; everything else is a view of that file. Read specs/principles.md for what's in scope (and what's deliberately not), and specs/dsl.md for the canonical language reference before touching grammar, parser, validator, or printer.

OSS boundary invariant

nowline is a standalone OSS repo. It never pushes to or triggers the proprietary services.

Permitted outbound writes from nowline:

npm publish -> @nowline/* packages on the npm registry
VS Code Marketplace + Open VSX extension publish
Homebrew tap formula update
Write to lolay/nowline-action (follow-only mirror, release pipeline only)

Prohibited (hard rule -- do not add exceptions without estate-level sign-off):

repository_dispatch into nowline-api, nowline-app, nowline-site, or nowline-infra
gh workflow run -R targeting those repos
Any write token held by a nowline workflow scoped to those repos

Consumers pull; nowline does not push:

nowline-app installs @nowline/* from npm; Renovate handles updates.
nowline-site pulls docs via the external/nowline git submodule (branch = main) + sync-docs; Renovate handles updates.
A consumer-owned schedule or consumer/human-initiated repository_dispatch may trigger a deploy -- but the initiator must never be nowline.

After the embed CDN retirement, nowline has no remaining tie to nowline-infra. See docs/architecture.md -> "Dependency direction" in the workspace for the full estate-level mapping.

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.
