What is novelist AGENTS.md?

Repository guidance for Novelist, an agent-assisted novel-writing plugin that works with Codex, Claude Code, and Antigravity CLI. It identifies the official plugin files, generated project template, and boundaries between platform-specific adapters.

Use it when changing Novelist skills, its generated project scaffold, adapter metadata, marketplace entries, or scaffold export scripts.

It prevents edits in the wrong copy or location and keeps shared plugin workflows separate from platform-specific setup.

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 5.1	$0.01247	$0.01247
Opus 5.5	$0.00499	$0.00499
Sonnet 5.5	$0.00249	$0.00249
Haiku 4.5	$0.00125	$0.00125

Security

Grade A, and why

novelist 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 2mo 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.

Repository Purpose

This repository develops and distributes Novelist, an agent-assisted novel-writing plugin for Codex, Claude Code, and Antigravity CLI.

The repository root is not a novel workspace. The canonical plugin payload is plugins/novelist/. Generated novel projects come from plugins/novelist/assets/scaffold/.

Canonical Sources

plugins/novelist/skills/: all nine canonical plugin skills.
plugins/novelist/assets/scaffold/: the canonical generated-workspace scaffold.
plugins/novelist/.codex-plugin/plugin.json: Codex adapter metadata.
plugins/novelist/.claude-plugin/plugin.json: Claude Code adapter metadata.
plugins/novelist/plugin.json: Antigravity CLI adapter metadata.
.agents/plugins/marketplace.json: Codex repository marketplace.
.claude-plugin/marketplace.json: Claude Code repository marketplace.
scripts/create_scaffold.py: canonical standalone scaffold exporter.
scripts/create-scaffold.sh, .ps1, and .bat: thin platform entry points.

Do not recreate .agents/skills/ or a novel scaffold at the repository root. Do not edit installed plugin cache copies.

Adapter Boundaries

Keep shared workflows in plugins/novelist/skills/. Do not fork complete skill trees by host.

skills/*/agents/openai.yaml is Codex/OpenAI presentation metadata.
Claude-specific packaging belongs under .claude-plugin/.
Antigravity's root plugin.json accepts only its documented minimal fields.
Host-specific image-generation instructions belong in create-visual-asset/references/.
The shared visual workflow must stay provider-neutral and must not claim an image was generated when no raster provider is connected.

Scaffold Contract

Novel source files use Markdown with YAML frontmatter. Documentation files named README.md, AGENTS.md, and CLAUDE.md do not need source frontmatter.

The canonical scaffold must remain self-contained inside the plugin. Never add runtime reads from the repository root, symlinks, or hardlinks. Preserve:

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.
