What it does

Herdr Kit Workflows is an agent skill from mastra-ai/mastra. Set up and operate Herdr Kit safely: install and configure the plugin and Mastra Code integration, manage Review and Work repository scope, open primary repository workspaces, synchronize managers, materialize or dematerialize managed worktrees, and update Herdr Kit settings or shortcuts.

Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Git worktrees. It works with Mastra. The repository describes itself as: Mastra is the modern TypeScript framework for AI-powered applications and agents.

When your agent uses it

  • Tasks that involve Git worktrees

Example prompts

  • “/herdr-kit-workflows”

Requirements

  • Python 3
  • A credential in AUTHORITATIVE_MANAGER_KEY

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Install the plugin and official Mastra Code integration
  2. Resolve the installed plugin as above and inspect its current README.md for the exact supported launcher settings and suggested…
  3. Configure required launcher commands in the Herdr-managed plugin integrations.env documented by that installed version. Preserve mode…
  4. Add only the shortcuts the user requests to ~/.config/herdr/config.toml. Plugin installation intentionally does not edit personal…
  5. Validate and apply configuration
  6. Start new Mastra Code sessions through the official Herdr integration before relying on lifecycle state or PR labels.

What it can do on your machine

Read from SKILL.md and the folder at commit b98829a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • AUTHORITATIVE_MANAGER_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Herdr Kit Workflows loads about 3.9k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 1,366 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~3.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,366 words (~3,903 tokens).

“Use Herdr Kit's supported Herdr and protocol-1 interfaces for setup, configuration, repository scope, synchronization, and worktree lifecycle operations.”
