AGENTS.md

fluxwing-skills AGENTS.md is an instructions file for Codex, OpenCode from trabian/fluxwing-skills. It costs 523 tokens per session, scanned B, original, MIT.

Repository instructions for developing and maintaining the Fluxwing collection of coding skills. They describe its folder layout, commands, file style, and testing guidance.

In plain words
What is it for?
Setting up the project, checking skill files, running documentation previews, and following its naming, formatting, and test practices.
Why use it?
They give contributors one shared set of rules for finding files, running the documentation site, installing skills, and keeping generated output separate.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths.

This is trabian/fluxwing-skills's own configuration. It tells Codex and OpenCode how to work on fluxwing-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 fluxwing-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 B, and why

fluxwing-skills AGENTS.md scanned grade B with 1 finding 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 8d 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.

Repository Guidelines

Project Structure & Module Organization

Fluxwing skills live under .claude/skills/<skill-name>/ with consistent docs/, templates/, schemas/, and scripts/ folders; treat bundled assets as the canonical source and adjust them deliberately. Workspace output belongs in ./fluxwing/ and should stay untracked, while site collateral is under docs/ and helper automation sits in scripts/.

Build, Test, and Development Commands

./scripts/install.sh provisions all seven skills globally to ~/.claude/skills, and ./scripts/uninstall.sh removes them. Serve the documentation site with npm run docs:dev, which launches an http-server on port 8080 for quick visual checks. When auditing skill files, lean on the helper commands in TODO.md (for example ls ~/.claude/skills/fluxwing-*/SKILL.md) instead of ad-hoc globbing.

Coding Style & Naming Conventions

Markdown files use sentence-case headings, one blank line between sections, and fenced code blocks with language hints. JSON and .uxm metadata are formatted with two-space indentation and ordered keys where practical; keep identifiers lowercase with hyphen separators (uxscii-component-viewer). YAML front matter in SKILL.md files mirrors that structure—stick to lowercase keys and quote strings only when needed. Shell scripts should remain POSIX/bash compatible, start with #!/bin/bash, and prefer explicit set -euo pipefail guards.

Testing Guidelines

There is no automated test harness yet, so rely on the manual flows captured in TODO.md: exercise each skill via Claude prompts ("Create a button", "Build a login screen") and verify the resulting files populate ./fluxwing/. After edits, rerun ./scripts/install.sh to update the global skills, and spot-check schema changes against the existing templates in each skill's schemas/ folder. Document any gaps or regressions directly in TODO.md to keep the manual test matrix current.

Commit & Pull Request Guidelines

Recent history favors compact, descriptive commit subjects (Add local development server for GitHub Pages, site fixes); follow that pattern and include detail in the body only when necessary. Each PR should call out the affected skill(s) or docs section, summarize manual test coverage, and link any related issues. Attach screenshots or terminal captures when tweaking docs or install flows, and avoid merging without another maintainer reviewing schema or template changes.

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.
