check-prereq-python

check-prereq-python is a skill for Claude Code from diagrid-labs/dapr-skills. It costs 44 tokens per session (605 once invoked), scanned A, original, MIT.

A prerequisite checker for building Dapr Workflow applications in Python. Dapr Workflow coordinates steps in long-running applications.

In plain words
What is it for?
Use it to check the operating system, Python language support, uv, Python 3.12 or newer, Docker or Podman, and the Dapr CLI.
Why use it?
It identifies whether the required Python tools, container runtime, Dapr command-line tool, and Python language support are available before development starts.

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

check-prereq-python 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 7d 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

Check Prerequisites for Dapr Workflow Python

Overview

This skill checks whether all prerequisites are installed for building Dapr Workflow applications in Python. Run this skill before using the create-workflow-python skill.

Prerequisites

The following must be installed:

Prerequisite Checks

Run ALL of these checks. Check steps 2-6 in parallel. Track which checks pass and which fail.

Step 1: Detect Operating System

Read the file at ../shared/prereq-detect-os.md and follow those instructions.

Step 2: Check the Python LSP plugin

Read the file at ../shared/prereq-check-python-lsp.md and follow those instructions.

Step 3: Check uv

Read the file at ../shared/prereq-check-uv.md and follow those instructions.

Step 4: Check Python SDK version

Read the file at ../shared/prereq-check-python-sdk.md and follow those instructions.

Step 5: Check Docker or Podman

Read the file at ../shared/prereq-check-docker-podman.md and follow those instructions.

Step 6: Check Dapr CLI

Read the file at ../shared/prereq-check-dapr-cli.md and follow those instructions.

Show final message

After all checks are complete, report the results:

  • List each check and whether it passed or failed.
  • For any failed checks, provide the relevant install link from the Prerequisites section.
  • If all checks passed, inform the user they can proceed with the create-workflow-python skill.

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.
