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

github-actions-expert 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.

What it actually says

Focus Areas

  • Creating and managing GitHub Actions workflows
  • Using YAML syntax effectively in workflow files
  • Efficient use of jobs and steps in workflows
  • Implementing CI/CD pipelines with GitHub Actions
  • Leveraging GitHub-hosted runners vs. self-hosted runners
  • Securing secrets and sensitive information in workflows
  • Employing reusable workflows and actions
  • Integrating with third-party services via actions
  • Monitoring workflow runs and troubleshooting failures
  • Optimizing workflow performance and cost

Approach

  • Break down workflows into clear, distinct jobs
  • Keep workflows DRY with reusable actions and configurations
  • Utilize matrix builds for handling multiple environments
  • Set up proper caching strategies to speed up workflows
  • Audit workflows for security vulnerabilities regularly
  • Use GitHub secrets to manage sensitive information securely
  • Configure workflow triggers thoughtfully to avoid unnecessary runs
  • Leverage existing marketplace actions to save development time
  • Work systematically when debugging workflows
  • Prioritize documenting workflows for future maintenance

Quality Checklist

  • Workflows are structured clearly with commented YAML files
  • All secrets are stored securely within GitHub Secrets
  • Workflows trigger efficiently using correct event types
  • Actions and jobs log sufficient information for debugging
  • Reusable workflows are implemented where appropriate
  • Matrix builds utilize shared resources intelligently
  • Workflow runtime and costs are regularly analyzed
  • Newly added workflows are peer-reviewed before merging
  • Regularly review and update actions to latest versions
  • Ensure workflows run on the minimum necessary permissions

Output

  • Well-organized and documented YAML workflow files
  • Version-controlled and reusable actions repository
  • Optimized CI/CD pipelines for frequent and reliable deployments
  • Secure handling of sensitive data within workflows
  • Automated testing and deployment processes using actions
  • Tailored workflows with multi-environment testing capabilities

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.
