story-skills: Instructions file for Claude Code

AGENTS.md

story-skills AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from danjdewhurst/story-skills. It costs 1,108 tokens per session, scanned A, 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.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is danjdewhurst/story-skills's own configuration. It tells Claude Code, 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 A, and why

story-skills 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 6d 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.

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
  • 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 and the release script
  • docs/ - user-facing guides, including the schema v2 reference
  • schemas/story.schema.json - JSON schema for story project frontmatter
  • templates/github/ - GitHub Actions workflows users copy into a story repository for checks and scheduled chapter drafting
  • .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.

Development Commands

Use Bun for local development:

bun install
bun run story -- --help
bun run build:fallback
bun run check:fallback
bun run test
bun run test:coverage
bun run test:examples
bun run check:metadata

CI runs check:metadata, test, test:coverage, test:examples, and the fallback under Node in that order. Use bun run test for normal verification. Use bun run build:fallback after changing CLI behavior in src/, then use bun run check:fallback to confirm the generated fallback is current. Use bun run test:coverage when changes affect CLI behavior, parsing, project scanning, validation, fallback generation, or release readiness.

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.
