F*ck YES... Anthropic just released most INSANE cheat code for Claude Code: Fable 5.2 brain → while Sonnet 5.5 builds → Opus 5.5 checks → Haiku 5.5 swarms 1 min + /advisor command = up to 3.4x CHEAPER here's how to setup it: first understand how it works: • This setup works for any tasks: Sonnet 5.5 builds, Opus 5.5 immediently check it, Haiku 5.5 swarm of agent search make research - at 80x cheaper per token than Fable • Fable 5.2 never writes code, it wakes up only 3 times: before a plan locks, when an error repeats, before "done" • you pay Fable prices only for decisions, the cheap models do all the rest here's how to setup it: 1 → run Claude update, Fable 5.2 needs Claude Code v2.1.321+ 2 → paste prompt below into Claude Code, it reads Anthropic's official advisor docs first 3 → it sets team at user level, so it works in every project: Sonnet main, Fable advisor, Haiku for subagents, a Opus checker 4 → it backs up your settings and shows every change as a diff before it applies it 5 → the part nobody tells you: there's one line that tells Sonnet 5.5 WHEN to call Fable. Without it, the advisor got called 0 times out of 198 in Anthropic's test full prompt + Anthropic's official advisor docs below Then read article to use Fable 5.2 at max out:

Claude Fable 5 is best used as an orchestrator that does the heavy reasoning and delegates token intensive but simpler tasks to cheaper models. 'fable-advisor' is your free and open-source plugin that does exactly that. New in fable-advisor: > A directive to Fable to minimize its own token usage (works surprisingly well) > GPT-5.5 as an implementer sub-agent via the Codex CLI (uses your ChatGPT sub so you don't pay extra) How to use it: 1. claude plugin marketplace add DannyMac180/fable-advisor && claude plugin install fable-advisor 2. /model fable

Claude Fable 5.2 just dropped. So I gave it and Opus 5.5 the same seven builds, one shot each. Fable beat Opus on almost every one. It also cost two to three times more per build. The setup I'd use instead: 1. Type /model opus in Claude Code 2. Type /advisor fable 3. Give it your biggest job Opus does the building. Fable only steps in at the hard moments and checks the work before it's done. In my tests that used less than half the Fable. It still cost less than running Fable on its own on every build. Most paid plans also get at least one free Fable reset this week. Go to Settings > Usage and tap Reset for free. On Max and Ultra, Fable's advice comes out of your normal plan limits. On Pro it's included until 16 November, then it bills to usage credits. If /advisor fable sends you to /model fable, run that once to say yes, then go back to /model opus. You need Claude Code 2.1.321 or newer, so run claude update first. Comment FABLE and I'll send you the full guide: the advisor setup and every prompt from all seven builds.

Claude Code tip: once Opus 5.5 is your main model, stop leaving Fable 5.1 sitting idle and stop burning Opus tokens on tasks Sonnet 5.5 can swarm put it on call with /advisor run /advisor fable Opus 5.5 plans and ships the code Sonnet 5.5 swarms the routine work at medium effort Fable 5.1 reads the full session, every tool call included, and only speaks up at three points: → before a plan: is this the right approach? → when the same error comes back: am I digging in the wrong place? → before "done": what did I miss? Fable 5.1 reviews. Sonnet 5.5 executes. Opus 5.5 ships Jev engineering is the same move one layer down: the forks that need no thinker (which file, which tool, retry or stop) go to Jev in under half a second, and the big model only sees the ones that split Plan on high. Delegate on medium. Keep Fable on call. - the full tree > Opus 5.5 on high runs the main session > explorer reads the code > worker edits and runs tests > researcher pulls the docs > all three on Sonnet 5.5 at medium effort > Fable 5.1 on call as the advisor paste the tree and this prompt into Claude Code ↓ "Rebuild my Claude Code setup around this tree: 1. Check ~/.claude/agents and .claude/agents for subagents that already fit explorer, worker and researcher. > Draft new ones only for missing roles > Give each model: sonnet, effort: medium > Skip any that pin a different model and list them 2. Set the main session to high via effortLevel in ~/.claude/settings.json, and set advisorModel to fable 3. Find anything that keeps the advisor off (CLAUDE_CODE_DISABLE_ADVISOR_TOOL, DISABLE_TELEMETRY, any variable that stops feature-flag fetching) plus CLAUDE_CODE_EFFORT_LEVEL, which overrides subagent effort. Report them, change nothing 4.

Claude Code tip, and it's absolute free f*cking gold: run Opus 5.5, Sonnet 5.5 and Fable 5.1 as one team and stop burning Opus tokens on routine work the setup in one line: plan on high, delegate on medium, keep Fable on call • who does what > Opus 5.5 on high - plans and ships the code > Sonnet 5.5 on medium - explorer reads code, worker edits and runs tests, researcher pulls docs > Fable 5.1 via /advisor fable - reads the whole session and speaks up only when it matters • when Fable 5.1 steps in -> before a plan: is this the right approach? -> when an error repeats: am I digging in the wrong place? -> before "done": what did I miss? Jev engineering takes it one layer lower: which file, which tool, retry or stop all go to Jev in under half a second, so the big models only see the real forks paste this into Claude Code ↓ "Rebuild my Claude Code setup: 1. Find subagents in ~/.claude/agents and .claude/agents that fit explorer, worker and researcher. Draft only the missing ones. Set each to model: sonnet, effort: medium. List any that pin a different model and leave them 2. In ~/.claude/settings.json set effortLevel to high and advisorModel to fable. 3. Report anything that disables the advisor (CLAUDE_CODE_DISABLE_ADVISOR_TOOL, DISABLE_TELEMETRY, flag-fetching blockers) and CLAUDE_CODE_EFFORT_LEVEL. Change nothing. 4. Add to ~/.claude/CLAUDE.md: consult the advisor before a large plan, when an error repeats, and before calling a long task done. Show every change as a diff. No edits until I say go." ↳

The best way to use Fable right now: > Fable advisor. Sonnet (or Opus) writes the code, Fable is the advisor. Use Fable for the high leverage, lower token judgement. Use Sonnet/Opus for the higher token implementation.

Claude Code tip that's pure f*cking treasure: Opus 5.5 + Sonnet 5.5 + Fable 5.1 as one team plan on high, delegate on medium, keep Fable on call the team: • Opus 5.5 (high) - plans and ships • Sonnet 5.5 (medium) - explores, edits, runs tests, pulls docs • Fable 5.1 (/advisor fable) - watches the session, speaks up when it counts Fable wakes up 3 times: 1. before a plan - is this the right approach? 2. when an error repeats - am I digging in the wrong place? 3. before "done" - what did I miss? Jev engineering goes one layer lower: which file, which tool, retry or stop go to Jev in under half a second, so the big models only see the real forks paste this into Claude Code 👇 "Rebuild my Claude Code setup around one team. 1. Subagents - reuse anything in ~/.claude/agents and .claude/agents that fits explorer, worker or researcher, draft the rest - all on model: sonnet, effort: medium - explorer and researcher read-only (Read, Grep, Glob, WebFetch), only worker gets Edit and Bash - each returns under 15 lines with file:line refs 2. Main session - in ~/.claude/settings.json set effortLevel to high and advisorModel to fable - report anything that overrides this (CLAUDE_CODE_DISABLE_ADVISOR_TOOL, DISABLE_TELEMETRY, CLAUDE_CODE_EFFORT_LEVEL) and change nothing 3. Add to ~/.claude/CLAUDE.md - consult the advisor before a plan touching 3+ files, when the same error shows up twice, and before calling a long task done - never let two subagents edit the same file Run /agents to confirm, then show everything as one diff. No edits until I say go." ↳

This is the best way to use Claude Fable in Claude Code without immediately hitting your limits. 1. Model set to Fable 5 2. Reasoning on Max 3. Instruct Claude to run a dynamic workflow where: 3a. Fable is the orchestrator 3b. Opus does the reasoning heavy phases Fable is so overpowered that you don't need its intelligence for every step. Let it orchestrate Opus or even Sonnet.

This is f*cking insane. I spent thousands of dollars before I split my work across three models put Opus 5.5 on the plan, Sonnet 5.5 on the legwork and Fable 5.1 on call, and you stop spending Opus money on jobs it was never needed for who does what: Opus 5.5, high effort: makes the plan and owns the final diff Sonnet 5.5, medium effort, three jobs: explorer reads the code, worker edits files and runs tests, researcher pulls the docs Fable 5.1, through /advisor fable: reads the whole session, but only when it gets called Fable is consulted at three points: → before a plan ships: is this the right approach? → when an error comes back twice: is the search stuck in the wrong place? → before a long task counts as done: what got missed? Jev engineering applies the same split to the smallest decisions. which file to open, which tool to run, retry or stop need no reasoning, so Jev answers them in under half a second and the big models only get the real forks run Opus on everything and you pay it to check whether a file exists paste this into Claude Code: "Rebuild my Claude Code setup around three tiers. Look in ~/.claude/agents and .claude/agents for subagents that already cover explorer, worker and researcher. Create only the missing ones, each with model: sonnet and effort: medium. If an existing one is pinned to another model, list it and leave it alone. In ~/.claude/settings.json, set advisorModel to fable. Set high effort for Opus inside modelSettings for claude-opus-5-5, because a top-level effortLevel does not apply to Opus 5.5. Report, without changing anything: CLAUDE_CODE_DISABLE_ADVISOR_TOOL, DISABLE_TELEMETRY or anything blocking feature-flag fetches, CLAUDE_CODE_EFFORT_LEVEL, which can override subagent effort, and whether Fable as advisor needs a one-time billing consent. If you can't tell, say so. Add one line to ~/.claude/CLAUDE.md: consult the advisor before a big plan, when the same error shows up twice, and before marking a long task done. Show every change as a diff first. Touch nothing until I say go."
