react-router: Skill for Claude Code

.github/skills/agentic-workflows/SKILL.md

agentic-workflows is a skill for Claude Code, Codex from remix-run/react-router. It costs 20 tokens per session (1,231 once invoked), scanned A, original, MIT.

Routing guidance for designing, creating, debugging, or upgrading GitHub Agentic Workflows. These are GitHub workflows that use an agent to perform tasks from repository events or instructions.

In plain words
What is it for?
Planning or modifying GitHub Agentic Workflow files, including their triggers, runtime settings, prompts, and repository-specific configuration.
Why use it?
It helps choose the right workflow-specific instructions for the request and accounts for optional repository rules. This avoids applying the wrong guidance to a workflow change.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents.

This is remix-run/react-router's own configuration. It tells Claude Code and Codex how to work on react-router 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 react-router configures →

About the project

React Router is a routing system for React applications that maps URLs to the interface shown on screen. Developers use it either as a small library within their own application structure or as part of a full React framework.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

agentic-workflows 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 1mo 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.

Agentic Workflows Router

Use this skill when a user asks to design, create, update, debug, or upgrade GitHub Agentic Workflows in this repository.

This skill is a dispatcher: identify the task type, load the matching workflow prompt/skill file, and follow it directly. Keep responses concise and ask a clarifying question if the correct prompt is unclear.

Repository overlay (optional):

  • If .github/aw/instructions.md exists, load it with @.github/aw/instructions.md after loading the matched prompt/skill.
  • Precedence: repository overlay instructions override upstream defaults when they conflict.
