AGENTS.md

story-skills AGENTS.md is an instructions file for Codex, OpenCode from danjdewhurst/story-skills. It costs 3,419 tokens per session, scanned C, original, MIT.

Repository instructions for Story Skills, a Bun/Node package that provides writing workflows and a command-line tool for maintaining story projects.

In plain words
What is it for?
Use them when changing Story Skills, its story command-line tool, its writing workflows, or the files that define and test those workflows.
Why use it?
They give a coding agent the project layout, development commands, implementation rules, and testing expectations so it can work consistently in the repository.

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

This is danjdewhurst/story-skills's own configuration. It tells Codex and OpenCode how to work on story-skills 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 story-skills 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 C, and why

story-skills 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 16d 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.

Agent Instructions

These instructions apply to the entire story-skills repository. CLAUDE.md is a symlink to this file so Claude Code reads the same instructions. Edit this file and leave the symlink in place.

Project Overview

Story Skills is a Bun/Node package that ships Agent Skills for fiction-writing workflows plus a small deterministic story CLI. The core format is plain markdown with YAML frontmatter. Skills guide creative workflows; the CLI handles mechanical maintenance such as validation, registry rebuilds, word counts, link checks, exports, and disposable builds.

Primary paths:

  • skills/ - published SKILL.md workflows and their reference files
  • src/ - source modules for the story CLI. src/commands.js and src/options.js are the command and option registries: add a command or flag there, and story --help, argument parsing, and project-path handling follow from the entry
  • bin/story.js - package binary entrypoint
  • skills/story-maintenance/scripts/story.js - Node-compatible bundled fallback CLI for copied skill installs
  • test/ - Bun tests
  • examples/ - sample Story Skills projects
  • scripts/ - CI check scripts, the release script, and issue-worktree.sh (see Git Workspace Hygiene For Automated Agents)
  • docs/ - user and contributor documentation, indexed by docs/README.md: getting started, core concepts, the project format (schema v2) reference, the CLI reference, the skills catalogue, writing workflows, continuity and analysis, series, import/export/builds, automation and CI, and the development guide
  • assets/ - plugin logo, screenshot, social preview, the README demo GIF (regenerate the GIF with vhs assets/demo.tape), and the README banner, feature icons, and skills diagram under assets/readme/
  • schemas/story.schema.json - JSON schema for story project frontmatter; test:examples validates every example against it, so update both together. Its date and language-tag patterns are generated: run bun run build:schema-patterns after changing how validate reads them
  • templates/github/ - files users copy into a story repository: GitHub Actions workflows for checks (story-checks.yml), scheduled chapter drafting (draft-next-chapter.yml), and an HTML review copy on GitHub Pages (review-copy.yml), plus the ISSUE_TEMPLATE/manuscript-note.yml reader-note form. The release script and check:metadata keep STORY_VERSION in all three workflows at the package version
  • .codex-plugin/, .claude-plugin/, .agents/ - plugin and marketplace metadata
  • plugins/story-skills - symlink to the repo root. Codex marketplace entries must point at a child plugin directory, so keep it a symlink rather than a copy.

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.
