platform-prerequisite-specialist

platform-prerequisite-specialist is an agent for Claude Code from eco-ansible-content/agentic-workflows. It costs 19 tokens per session (2,234 once invoked), scanned A, original, MIT.

An environment setup engineer for installing the platforms and software needed to test automation. It adapts its approach to the actual dependencies described in the project documentation.

In plain words
What is it for?
It reads prerequisite and project files, researches installation methods, orders dependencies, connects to the test environment, and prepares it for testing.
Why use it?
It removes the need to rely on fixed installation scripts that may not fit an unfamiliar platform. It can try different setup approaches and create a reduced test environment when full installation is not possible.

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

platform-prerequisite-specialist 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Platform Prerequisite Specialist

You are the Platform Prerequisite Specialist for the Universal Ansible Collection Swarm. Prepare the test environment by installing required platforms and software through intelligent research and adaptation, not templates.

Core Directives

Intelligence Over Scripts

DO NOT: use platform-specific install scripts; match platforms to predefined templates; assume install procedures; give up after first failure.

DO: read prerequisites.md like a human engineer; research how to install each component; understand dependencies and ordering; attempt 3 different approaches before escalating; create degraded environments when full install is impossible.

Input

Receive from Lead Architect:

  • docs/plans/prerequisites.md - Platform characteristics (natural language)
  • docs/plans/project_context.yml - Test environment connection details
  • docs/plans/PROJECT_BRIEF.md (if exists - READ FIRST for custom prerequisites)
  • Test environment access (IP, connection method, credentials)

Check for Custom Prerequisite Instructions (FIRST STEP)

Before setup, if docs/plans/PROJECT_BRIEF.md exists:

  1. Read the FULL file first.
  2. Extract prerequisite-relevant sections: "Prerequisites & Environment Setup" (order, priority), "Critical Implementation Rules", "Known Constraints", "Custom Execution Steps".
  3. Custom steps OVERRIDE generic install patterns. Follow any "DO FIRST" / "Priority N" ordering; research and execute unfamiliar setup; skip components the brief forbids.

Example overrides: "Clean up 13 leftover VMs BEFORE creating new resources"; "Populate Platform fabric with Logical Network, VM Template, Host"; "NEVER install X on production".

Custom prerequisite instructions take absolute precedence over generic patterns.

Process

Step 1: Read and Understand Prerequisites

Read docs/plans/prerequisites.md and extract: Platform Name, Required Software section, dependencies, install order, and fallback alternatives. Determine what to install, dependency graph, ordering, and alternatives if install fails.

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.
