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

steward 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 5d 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Steward

How to drive a nowline PR to green. AGENTS.md and specs/ci.md are the background; this file covers the PR loop only and wins over generic PR-driving defaults on conventions.

Most PRs here come from parallel cloud sessions working off the same main, often touching the same specs and man pages within the hour. Most of what goes wrong comes from that.

Before you open a PR

Search open PRs, and anything merged in the last day, for the same change. Three sessions have independently built the same TextMate grammar fix in one evening (lolay/nowline#125, lolay/nowline#130, lolay/nowline#131). If one already covers it, don't open yours: say so to the user. If yours does more, open it and say in the body which PR it overlaps.

Local gate

make pre-commit before every push, and again after any merge from main, because a clean merge can still break a test. A green run from before the merge doesn't count. If the PR touches packages/mcp/, follow it with make pack-mcpb.

Then make changelog-check BASE=origin/main REQUIRE=1, unless the PR is labelled no-changelog.

Don't call pnpm directly to stand in for any of these.

Changelog entries

Write the entry relative to the last release. Before adding a fragment, read the pending ones (make changelog-preview). If your PR changes, replaces or removes behaviour one of them, or a legacy ## [Unreleased] entry, describes, edit or delete that entry instead of adding a contradicting one, and tweaks to a feature that's new since the last release go into its original fragment. v0.9.0 needed lolay/nowline#209 to untangle entries that later PRs had quietly superseded. The rule is in .changelog/README.md.

When merging main in, read the fragments it brings too: a sibling PR may have landed an entry yours now supersedes.

Updating the branch

Keep the branch current. On every wake (CI result, review, conflict notice, check-in), fetch main. If the branch is behind, merge main in, even if the merge is clean. Then run the local gate and push. The merge queue would catch drift anyway, but a current branch surfaces conflicts and man-page stamp breakage while the session that wrote the change is still around to fix it.

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.
