What is local-action-verification?

A setup guide for using act, a tool that runs GitHub Actions workflows locally. It adds installation and runner scripts plus instructions in AGENTS.md so an AI coding agent can use them.

Use it to add local GitHub Actions verification to a repository, install act when needed, run workflows through the provided scripts, and document the process for Jules or another coding agent.

It allows CI checks to run before code is pushed to GitHub, making failures easier to catch during local development. Background execution and log polling help avoid agent timeouts.

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	$0.00025	$0.00878
Opus 5.5	$0.00010	$0.00351
Sonnet 5.5	$0.00005	$0.00176

Security

Grade B, and why

local-action-verification 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 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/install-act.sh, scripts/run-act.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Local Action Verification with act

You are setting up a repository so that Jules (or any agent) can run GitHub Actions workflows locally using act to verify code changes pass CI before pushing.

What You're Setting Up

Two scripts and an agents.md section that enable local CI verification:

install-act.sh — Installs act if missing (platform-aware, sudo fallback)
run-act.sh — Runs act in the background with log polling to avoid agent timeouts
AGENTS.md section — Instructions Jules reads to know how to use these scripts

Setup Steps

Step 1: Copy scripts to the repository

Copy the scripts/ directory from this skill into the target repository at scripts/act/:

Target structure:
scripts/act/
├── install-act.sh
└── run-act.sh

Make sure the scripts are executable:

chmod +x scripts/act/install-act.sh scripts/act/run-act.sh

Step 2: Add instructions to AGENTS.md

Append the following section to the repository's AGENTS.md file (create it if it doesn't exist). This is how Jules discovers the local verification capability:

## Local CI Verification

Before pushing code or opening a PR, verify changes pass CI locally using `act`.

### Prerequisites
- Docker must be running
- If `act` is not installed, run: `bash scripts/act/install-act.sh`

### How to Verify

1. Read `.github/workflows/` to find the CI workflow and identify the job ID
2. Run the verification script:
   ```bash
   bash scripts/act/run-act.sh "push -j <JOB_ID>"

With matrix: bash scripts/act/run-act.sh "push -j <JOB_ID> --matrix <KEY>:<VALUE>" 3. If the run fails, read the log output, fix the code, and re-run 4. After verification, clean up:

rm -f act_output.log
git checkout <any unintended file changes>

Configuration

Timeout: ACT_TIMEOUT=900 bash scripts/act/run-act.sh "..." (default: 600s)
Poll interval: ACT_POLL=15 bash scripts/act/run-act.sh "..." (default: 10s)
Custom image: pass -P ubuntu-latest=node:20-bookworm in the arguments for faster pulls

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
