SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Minimize overhead by bypassing automatic skill loading and executing only whitelisted tasks.

Core Features & Use Cases

  • Selective execution: Skip all skills by default and activate only the whitelisted ones.
  • Config-driven whitelisting: Read allow-list from CONFIG_DIR and resolve allow-list path depending on whether it ends with .json.
  • Deterministic, low-latency runs: Ensure task execution proceeds with minimal overhead when fast-mode is enabled.

Quick Start

Set CONFIG_DIR to your fast-mode configuration path and ensure the allow-list JSON lists the permitted skills.

Frequently Asked Questions about fast-mode

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I reduce task execution latency by skipping automatic skill loading?

You can reduce task execution latency by enabling fast-mode, which bypasses automatic skill loading and directly executes only the tasks specified in a local allow-list. This ensures minimal overhead and deterministic behavior for permitted workflows.

How do I configure a whitelist for selective task execution?

You configure a whitelist by setting the CONFIG_DIR environment variable to your configuration path and ensuring the allow-list JSON file lists the permitted skills. The system resolves the allow-list path depending on whether it ends with .json.

What is exact-name whitelisting for skill execution?

Exact-name whitelisting is a mechanism that enforces task execution exclusively for skills whose names precisely match entries in the configured allow-list. It skips all other skills by default to guarantee low-latency runs.

Can I use a non-JSON configuration file for the fast-mode allow-list?

No, the fast-mode allow-list resolution specifically checks if the configured path ends with .json. You must provide a JSON formatted file to ensure the environment-configured allow-list is correctly read and enforced for whitelisting.

Why does fast-mode bypass all skills by default?

Fast-mode bypasses all skills by default to minimize overhead and achieve minimal latency during task execution. It selectively activates only the whitelisted skills, ensuring deterministic behavior without the performance penalty of loading unused skills.

When should I avoid using fast-mode for task automation?

You should avoid using fast-mode when your workflow requires dynamic skill loading or relies on skills not included in the exact-name allow-list, as the system skips all non-whitelisted skills to ensure low-latency execution.
