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.

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 | $0.00013 | $0.00439 |
| Sonnet 5 | $0.00005 | $0.00176 |
| Haiku 4.5 | $0.00003 | $0.00088 |
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 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.
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
actif missing (platform-aware, sudo fallback) - run-act.sh — Runs
actin 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-bookwormin the arguments for faster pulls
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.
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.

local-action-verification is a skill published in the GitHub repository google-labs-code/jules-skills (93 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 25 tokens to every session and 878 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
