A GitHub Actions setup tool that detects a repository's programming languages and creates automated jobs for tests, linting, formatting, and vulnerability checks. It also adds matching Makefile commands for running these checks locally.

Use it to add a standard CI workflow to Go, JavaScript or TypeScript, Python, Rust, Zig, Ruby, or shell projects.

It removes the manual effort of creating and connecting continuous integration checks. CI means automated checks that run when code changes, helping catch problems before they are merged.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

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	$0.00158	$0.02901
Opus 5	$0.00079	$0.01451
Sonnet 5	$0.00032	$0.00580
Haiku 4.5	$0.00016	$0.00290

Measured 4d ago against content hash 23888951a48f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-07, from the pricing page.

Security

Grade A, and why

set-up-ci scanned grade A 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Set-Up CI

Detect the project's language(s), create a GitHub Actions CI workflow with appropriate parallel jobs (test, lint, format, vulnerability check), and create matching Makefile targets for local development.

Workflow

1. Detect Project Type

If the user specified a language in their request (e.g., go-cli, go-library, javascript, python, rust, ruby, shell, zig, zsh), use it directly instead of scanning for markers. Still perform sub-detection steps as needed (e.g., JS package manager detection for javascript, or verifying main.go/cmd/ for go-cli vs go-library).

Scan for language and file-type markers using Glob. Exclude node_modules/, .yarn/, vendor/, and other dependency directories from all searches to avoid false positives from vendored code.

Marker(s)	Language
`go.mod`	Go
`package.json` + source files (`.js`, `.ts`, `.jsx`, `.tsx`, `.mjs`, `.mts`, excluding `node_modules/`)	JavaScript/TypeScript
`pyproject.toml`, `setup.py`, `requirements.txt`	Python
`Cargo.toml`	Rust
`build.zig`, `build.zig.zon`	Zig
`Gemfile`, `*.gemspec`	Ruby
`.sh`, `bin/`, `scripts/*`	Shell
`*.zsh`, `#!/usr/bin/env zsh` shebangs, `.zshrc`, `.zshenv`	Zsh

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.

set-up-ci is a skill published in the GitHub repository cboone/agent-harness-plugins (2 stars, last pushed 1mo ago), licensed MIT. It adds 158 tokens to every session and 2,901 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
