The Hidden Playbook

Name: The Hidden Playbook
Author: Bernard W. Piccione

The advanced Claude AI companion guide — power prompts, agentic patterns, and the controls that keep them safe.

Once a team is past basic prompting, the interesting problems change shape: chained workflows that must be reproducible, assistants that touch real systems, output that has to survive review by someone who was not in the room. The Hidden Playbook is the companion volume for that stage — advanced features, multi-step and agentic patterns, evaluation habits, and the specific guardrails that let an IT organisation put them in front of users without inheriting an audit finding.

From the back cover

The Complete Guide to Claude AI — From First Prompt to Power User. 20 diagrams and 175+ ready-to-use prompts.

Volume 2 (The Hidden Playbook): advanced features, power prompts, and apps that think.
Volume 1 (The Claude Playbook): beginner fundamentals including prompt engineering and data analysis.

Written for

IT leaders whose teams have outgrown ad-hoc prompting and now need repeatable, reviewable workflows.
Automation and integration owners connecting an assistant to internal systems and documents.
Security architects assessing agentic patterns, tool access, and blast radius.
Power users building internal tooling who want the advanced surface area explained properly.

Not written for

Complete beginners — start with Volume 1 of the Claude Playbook.
Readers seeking consumer productivity tips unrelated to enterprise controls.

Framework

Inside the companion volume

01
Advanced context engineering
Structuring long inputs, source grounding, and citation discipline so answers can be checked.
02
Power-prompt architecture
Composable prompt components, deterministic output contracts, and version control for prompt assets.
03
Multi-step and agentic workflows
Decomposition, checkpoints, and where a human approval must sit inside an automated chain.
04
Tool and system access
Least-privilege patterns for assistants that read or write to real systems, and how to bound blast radius.
05
Evaluation and regression habits
Building a small golden-set harness so a prompt change does not silently degrade quality.
06
Apps that think — internal tooling patterns
Where assistant-built tools belong in the estate, and the support model they need to stop being shadow IT.
07
Failure modes and guardrails
Prompt injection, data leakage through context, over-trust, and the practical controls for each.

From the book

“An agent with tool access is a service account with opinions. Scope it like one.”
The Hidden Playbook

“If you cannot re-run last month's prompt and get a comparable answer, you do not have a workflow. You have an anecdote.”
The Hidden Playbook

“Every automated chain needs one place where a human can say no, and it should be before the irreversible step.”
