Ai Dive Deep
A free operator's field manual for Claude Code mods, agents and evals — Edition 19.1, 57 chapters, no email gate.
Edition 19.1 is the freshest free read we've found on Claude Code, and the mod chapter is the proof: six mods built, tested and validated against Claude Code 2.1.288 in 32 minutes, with four bugs caught by 42 engine tests before anything ran live. The catch is audience. This assumes you live in a terminal, run subagents and care about evals — Chapter 56's skill leaderboard, where a 23-agent swarm read 118 repos from source, is not a beginner's entry point. There's no support contract behind it either, so budget for reading, not for a vendor to fix your build. Compare with official Claude Code docs (neutral, thinner, free) or a paid course (hand-held, slower, costs money). Pick this if you

Skip it if you want video-led onboarding or a vendor contract — this is a self-serve written manual you read and apply yourself, not a support relationship.
The manual is free, but the tooling it documents isn't: running the Opus 5.5 and Sonnet 5.5 patterns it teaches means paying Anthropic for your own tokens.
At $0 with no email gate and no account, this sits below nearly every paid AI course or subscription manual — you pay only for the models you run while applying it. Teams already paying for Claude Code seats get the reading for nothing. Against paid Claude Code courses it wins on freshness (Edition 19.1, Oct 3, 2026) and loses on hand-holding and on having anyone to call.

What's new in Ai Dive Deep
Checked yesterdayAcross the latest 5 updates: 1 feature update and 4 changelog entries.
Edition 19.1 — A reference page for Claude Code mods
Adds a mods reference covering what a mod is, how it differs from settings hooks, skills, MCP servers and the status line, install via /plugin or --plugin-dir, and a copy-paste first mod validated on Claude Code 2.1.288.
Edition 19 — Claude Code mods: six built and tested in 32 minutes
Chapter 57 covers mods as function hooks that rewrite or refuse events and draw UI, with six mods built in one session, 42 engine tests passing and four bugs caught before anything ran live.
Edition 18 — Read before you install: skill leaderboard from 118 repos
Ranks 700 repos, has a 23-agent swarm read 118 from source across about 3.78M tokens in 35.2 minutes, and pins nine skills and plugins to the commit a vetter read.
Edition 17.1 — Opus 5.5 and Sonnet 5.5 field guides
Adds field guides for Claude Opus 5.5 and Sonnet 5.5 with checked sources and the same planted-bug review run on both models across effort levels.
Edition 16 — What agents can't see
Covers reviews that caught the code and a menu design nobody rendered, illustrating where agent review fails.

About Ai Dive Deep
Ai Dive Deep (published as Vlad's Playbook) is a free, browser-read field manual for running AI as an operating system rather than a pile of disconnected tabs. Edition 19.1 landed October 3, 2026 with 57 chapters, 3 live embedded case studies, and no email gate — the whole library reads for $0. Four learning paths (build your first workflow, make agents reliable, ship a product, roll AI out to a team) each run four chapters, so you start at the job you actually have instead of chapter one. The author is Vlad Podoliako, who runs Belkins and Folderly and writes from what shipped. Edition 19.1 added a reference page for Claude Code mods: what a mod is, how it differs from settings hooks, skills, MCP servers and the status line, install via /plugin, --plugin-dir or CLAUDE_CODE_PLUGIN_DIRS, six real mods built and tested in 32 minutes, and a copy-paste first mod that refuses an unquoted zsh =word and hands Claude the fix — validated with validate, strict tsc and the engine test runner on Claude Code 2.1.288. Edition 19 ran 42 engine tests and caught four bugs before any mod went live. Also on the shelf: Edition 18's skill leaderboard, where a 23-agent swarm read 118 repos from source (700 ranked, 36,328 skills tracked, about 3.78M tokens over 35.2 minutes) and nine installs went in pinned to the commit a vetter read; Edition 17.1's Opus 5.5 and Sonnet 5.5 field guides with same-task receipts; MCP connectors, hooks and custom subagents, headless Claude in CI via claude --print, evals (smoke, regression, golden), voice agents wired from STT plus LLM plus TTS to a live phone number, and a Radar index ranked by lead time. It reads like an operator's log, and the misfires stay in.
Behind the Verdict
Strengths: the material is dated and receipted rather than narrated. Edition 19.1's mod page names what it was checked against (Claude Code 2.1.288), what tested it (validate, strict tsc, the engine's own runner), and what broke (four bugs, plus a guard that blocked its own author an hour later). Chapter 56 does the same for skills: 700 repos ranked, 173 shortlisted by code, 118 read from source by 23 agents across roughly 3.78M tokens in 35.2 minutes, and the most-starred repos deliberately skipped with reasons from their own files — hooks at session and subagent start, an installer writing into CLAUDE.md, a background claude -p. Chapter 55 is equally concrete: on 22 and 29 September, across effort levels and two runs per setting, Sonnet 5.5 at high found all six planted bugs with about half of Opus 5.5's output tokens, and only Opus 5.5 also reported the real bugs nobody planted. You also get breadth beyond coding — voice agents from STT plus LLM plus TTS to a live phone number (Chapter 27), token math and caching (Chapter 29), six stages from idea to deploy (Chapter 31), and a 30-day plan for team rollout. Weaknesses: it is one operator's account, drawing on his own companies and portfolio, so it is perspective rather than vendor-neutral documentation. Screenshots and covers are reconstructions with decoy repo names because the underlying boards carry client work, and the changelog notes evaluation work on newer model guides is still ahead. There is no video, no hand-holding, and no procurement paperwork — no SLA, no support desk. Where it fits: engineers already running Claude Code who need current, checked patterns for mods, skills, hooks, MCP servers, evals and CI. Where it doesn't: complete beginners, teams that need a vendor to sign something, and anyone shopping for a drag-and-drop agent builder.

Real-world workflow fit
Concrete scenarios for the personas Ai Dive Deep actually fits — and what changes day-one when you adopt it.
Open the Edition 19.1 mod reference, copy the first mod that refuses an unquoted zsh =word, load it with --plugin-dir, then run validate, strict tsc and the engine test runner the way Chapter 57 did on 2.1.288.
Outcome: A working, tested mod on your machine the same session instead of a prompt pattern you hope works — the same path that produced six mods in 32 minutes with four bugs caught before anything ran live.
Use Chapter 56's copy-paste check to count a repo's skills, listing characters, hooks and risky lines, then pin the install to the commit you actually read.
Outcome: You skip the repos the swarm flagged — hooks at subagent start, installers writing into CLAUDE.md, background claude -p — and keep context cost near 2,100 characters instead of 675,367.
Run Chapter 54 and 55's same planted-bug review across effort levels for Sonnet 5.5 and Opus 5.5, two runs per setting, then read the token counts side by side.
Outcome: A defensible answer on whether the cheaper model is enough — Sonnet 5.5 at high found all six planted bugs at roughly half Opus 5.5's output tokens, while only Opus 5.5 also reported the bugs nobody planted.
Use Cases
- Build a first Claude Code mod and test it with validate, strict tsc and the engine runner before it goes live.
- Audit skills before installing: count a repo's skills, listing characters, hooks and risky lines first.
- Run headless Claude in CI using claude --print in production.
- Wire up MCP connectors, install paths, and custom MCP servers.
- Set up CLAUDE.md rules and cowork configurations for consistent agentic coding.
- Stand up regression and golden evals with review agents so an agent knows when to stop.
- Compare Opus 5.5 and Sonnet 5.5 on the same planted-bug review before a model switch.
- Run six concurrent Claudes using parallel subagents, tmux, worktrees and named sessions.
Models Under the Hood
as of 2026-10-11
Limitations
- This is a web-based field manual you read in a browser, not a software product or service with an API.
- It is one operator's opinionated account drawn from his own companies and portfolio, so it is perspective rather than vendor-neutral documentation.
- Claude Code 2.1.288 is named only as the version the mod example was validated on, not as an integrated capability.

Ideal for
Claude Code operators, engineers and team leads who want current, receipt-backed material without paying for a course.
What this tier adds
Starting tier: the entire 57-chapter library, four learning paths, the Radar index and the workflow planner, with no email gate and no account.
Where the pricing makes sense
The company stage and team size where Ai Dive Deep's pricing actually pencils out — and where peers do it cheaper.
At $0 with no email gate and no account, this sits below nearly every paid AI course or subscription manual — you pay only for the models you run while applying it. Teams already paying for Claude Code seats get the reading for nothing. Against paid Claude Code courses it wins on freshness (Edition 19.1, Oct 3, 2026) and loses on hand-holding and on having anyone to call.
Setup time & first value
How long it actually takes to get something useful out of Ai Dive Deep — broken out by persona, not the marketing-page minute.
Reader, experienced Claude Code operator: minutes, since each chapter stands alone and you can jump straight to Chapter 57. Engineer applying a pattern end to end: an afternoon, and the mod walkthrough itself took 32 minutes. Team lead building an adoption business case: a few evenings across the four-chapter team rollout path. Complete beginner: longer than you'd like — start at the prologue.
Switching to or from Ai Dive Deep
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From scattered Claude Code docs and bookmarks: work the four learning paths in order, each four chapters, instead of tab-hopping.
- →From paid AI courses: jump to Chapter 57 (mods), Chapter 56 (skills) and Chapters 54–55 (model guides) for the current material.
- →From your own CLAUDE.md sprawl: rebuild conventions using Chapter 37 and the CLAUDE.md rules and cowork setup references.
- ↗To official Claude Code documentation: when you need vendor-neutral reference rather than one operator's tested patterns.
- ↗To a paid cohort course: when you want scheduled, hand-held instruction with someone accountable for your progress.
- ↗To the Anthropic SDK directly: Chapter 30 covers exactly when to drop Claude Code and build against the SDK yourself.
