分工挺合理，但什么时候叫顾问介入，怕是比选模型还难。

Funny that the official Anthropic tip is basically "use Opus less."

That's a slick tip! Using Haiku to swarm simpler tasks while Sonnet focuses on the heavy lifting could save so much time. Makes you rethink how you allocate resources in AI.

Why is no one talking about this? Official Anthropic recommendation for Claude Code: stop wasting Opus 5.5 compute on tasks Haiku 5.5 can swarm, while Sonnet 5.5 handles core development. switch the architect model into standby using /advisor claude -> advisor opus -> subagents haiku Sonnet 5.5 powers the main workflow at maximum effort, drafting code changes and executing test suites Haiku 5.5 subagents index the repository in parallel at 340 tokens/sec, discovering files and reviewing technical documentation Opus 5.5 remains on standby as an expert consultant, stepping in only during three key scenarios: -> prior to committing to a strategy: does the blueprint lack authentication edge cases or schema rules? -> when a test fails repeatedly: are we tackling the root issue or wasting time in a rabbit hole? -> before marking the task complete: did recent diffs introduce silent bugs, and are baseline checks satisfied? Opus 5.5 assesses. Sonnet 5.5 builds. Haiku 5.5 executes concurrently Jev engineering applies this identical structure one level down: automated logic requiring zero reasoning (selecting files, invoking tools, retrying or cancelling) completes in 16ms, so heavy models trigger only when execution paths split Plan at max power. Delegate at mid power. Keep Opus on standby On-call Opus 5.5 inspects overall session history and catches deep structural flaws Lead Sonnet 5.5 performs edits, writes core logic, and manages test environments Haiku 5.5 subagents run AST parsing, grep queries, and API doc analysis concurrently JEV micro-fork layer processes 1,500+ routing rules in under 16ms Expert model stays silent during basic terminal commands to preserve context window Configure my Claude Code workspace for hierarchical advisor orchestration: 1. Verify ~/.claude/settings.json and project-level configs for model role alignment (main, subagents, and advisor) Set main session model: sonnet with high effort level for primary execution Set subagents model: haiku with effortLevel: medium for parallel file discovery and doc gathering Set advisor model: opus on call for high-level analysis 2. Turn on the advisor tool inside ~/.claude/settings.json: Define advisorModel as claude-opus-5-5 Enable subagent parallel dispatcher pool (3x workers) 3. Establish automatic advisor review checkpoints in ~/.claude/CLAUDE.md: Call /advisor opus prior to finalizing multi-file architectural changes Trigger /advisor opus automatically whenever the same compiler or test error happens twice Require an advisor diff contract audit prior to completing tasks or staging git commits 4. Restrict subagent execution boundaries: Haiku subagents must return only structured AST summaries and doc snippets without bloating the primary session context Display all configuration diffs before applying changes.

THIS IS PURE F*CKING GOLD Anthropic just shared one of the best tricks for Claude Code. The idea: run Sonnet, Haiku and Opus 5.5 at the same time, each one doing only what it's best at. Better results and way fewer tokens, because every task lands on the right model. You just start Claude Code like this: claude --model sonnet --advisor opus here's how it splits: → Sonnet 5 runs the session and writes the code → Haiku 5.5 explores files and docs in parallel → Opus 5.5 stays on call as advisor for the big decisions → you stop burning Opus context on tasks that don't need it Opus only steps in at three moments: → before a plan locks → when the same error hits twice → before calling it done Sonnet builds. Haiku explores. Opus reviews. 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 milliseconds, and the big models only see the ones that split the full tree > Sonnet 5 runs the main session and edits code > search maps the repo on Haiku 5.5 > grep finds call sites on Haiku 5.5 > docs pulls the API reference on Haiku 5.5 > Opus 5.5 on call as advisor, reads the full transcript when consulted > JEV routes micro-forks in milliseconds paste the tree and this prompt into Claude Code ↓ "Reconfigure my Claude Code setup around this tree: 1. Run the main session on Sonnet 5 with Opus 5.5 as advisor. 2. Create three read-only Haiku 5.5 subagents: search (maps the repo), grep (finds call sites), docs (pulls the API reference). 3. Add one rule to CLAUDE.md: consult the advisor before locking a plan, after the same error twice, and before calling a task done. 4. Route fast deterministic forks (tool choice, path selection, retries) through JEV. Show me every change as a diff first. No edits until I say go." ↳ save it, it'll come in handy.

This Claude Code tip saved me thousands of dollars. once Opus 5.5 is your main model, stop burning it on work Sonnet 5.5 can do, while Fable 5.1 sits idle hand the grunt work to Sonnet 5.5 subagents and put Fable 5.1 on call run /advisor fable Opus 5.5 plans and ships the final code Sonnet 5.5 subagents read, edit and run the tests 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? Sonnet 5.5 builds. Fable 5.1 reviews. 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 models only see the ones that split anyone still running one model for everything is paying Opus prices to decide whether a file exists - the full tree > Opus 5.5 on high runs the main session > explorer reads the code on Sonnet 5.5 > worker edits and runs tests on Sonnet 5.5 > researcher pulls the docs on Sonnet 5.5 > all three on medium > Fable 5.1 on call for main and every subagent 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) plus CLAUDE_CODE_EFFORT_LEVEL, which overrides subagent effort. Report them, change nothing 4.

This workflow will save you thousands with Claude. Run Opus 5.5, Sonnet 5.5, Haiku 5.5, and Fable 5.1 together, and stop spending Opus tokens on work that doesn't need Opus. The entire idea in one line: Opus plans, Sonnet edits, Haiku reads, Fable reviews at decision points. Roles, broken down: - Opus 5.5, high effort, owns the plan and reviews the final code - Sonnet 5.5, medium effort, is the worker: edits files, runs tests - Haiku 5.5, low effort, splits into explorer (searches and reads the codebase) and researcher (pulls docs). it's the first Haiku with an effort setting - Fable 5.1, set with /advisor fable. Opus calls it at decision points, and it gets the full transcript each time Three moments Opus tends to call it: → before committing to a plan: is this the right approach? → the same error shows up again: is this going nowhere? → before marking the task done: did something get skipped? Why Haiku only reads: Anthropic's launch post says Sonnet 5.5 and Opus 5.5 are still the better choice for complex agentic coding (Terminal-Bench 4.0: 39.2% for Haiku 5.5, 70.6% for Sonnet 5.5) and that Haiku 5.5 fits narrowly scoped subagent work. so it gets the lookups, not the edits. Anyone still running one model for everything is paying $4 per million input tokens to check whether a file exists. Haiku 5.5 does it for $0.10. Drop this into Claude Code 👇 "Rebuild my Claude Code setup around this structure: Confirm Claude Code is v2.1.293 or later, so the haiku alias resolves to Haiku 5.5. If it isn't, stop and tell me to run claude update. Look through ~/.claude/agents and .claude/agents for subagents already covering explorer, worker, and researcher. Only create new ones for roles that are missing. Set model: haiku, effort: low on explorer and researcher, with no Edit or Write tools. Set model: sonnet, effort: medium on worker. If an existing subagent is locked to a different model, leave it as is and just list it. Name the explorer subagent Explore so it overrides the built-in one, which otherwise runs on my main model. In ~/.claude/settings.json, set advisorModel to fable, and set effortLevel to high for claude-opus-5-5 under modelSettings. A top-level effortLevel in user settings doesn't apply to Opus 5.5. Check for anything disabling the advisor: CLAUDE_CODE_DISABLE_ADVISOR_TOOL, DISABLE_TELEMETRY, or anything blocking feature-flag fetches. Also check CLAUDE_CODE_EFFORT_LEVEL, which overrides subagent effort settings, and CLAUDE_CODE_SUBAGENT_MODEL_FORCE, which makes Claude Code ignore subagent model fields. Report what you find. Don't change any of it yet. 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. Wait for my go-ahead before touching anything."

Sonnet 5.5 builds. Haiku 5.5 swarms. Opus 5.5 merges and ships Jev engineering runs the identical pattern one layer down: mechanical decisions that need no reasoning (which file to open, which tool to invoke, retry or abort) execute in 16ms, so the frontier models only wake up when execution paths actually diverge Plan on high. Delegate on medium. Keep Haiku 5.5 on P2P call. - the full team setup > Opus 5.5 on high coordinates the session and synthesizes PRs > teammate-ux builds client state inside a separate git worktree > teammate-back writes endpoints and handles Redis atomic locks > teammate-scout runs invariant fuzzing and AST parsing on Haiku 5.5 at 340 tok/s > all teammates communicate directly over peer-to-peer messaging without coordinator drag > tasks.json manages file-level mutex locks so nobody steps on another worktree paste the setup and this prompt into Claude Code below: "Configure my Claude Code workspace for autonomous agent teams: 1.

WHOEVER LEAKED THIS CLAUDE CODE SETUP DESERVES A RAISE I thought the best way to use Claude Code was to just throw Opus at everything. Apparently not. Anthropic’s setup is much more interesting: → Sonnet 5.5 runs the main session and actually builds the thing → Haiku 5.5 swarms the repo for file discovery, AST scans, grep, and docs → Opus 5.5 stays in the background as the architect → Opus gets called in before big plans, after repeated test failures, and before shipping → JEV handles the boring mechanical routing in ~16ms so frontier models only wake up when real reasoning is needed so you get: Opus reviews. Sonnet builds. Haiku swarms. JEV routes. the interesting part isn’t using multiple models. it’s giving each model a different job. Instead of burning Opus context on finding files and running routine commands, you save it for the moments where architectural judgment actually matters. Plan on high.Delegate on medium. Keep Opus on call.

this is straight f*cking gold for anyone on Claude Code you already pay for Fable 5.1, and while Opus 5.5 does all the work it just sits there one command puts it on your session as a senior reviewer: /advisor fable Opus 5.5 keeps writing the code Fable 5.1 reads the whole session, every tool call included, and speaks up at three moments only: > 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. Opus 5.5 ships Jev engineering does the same thing one layer down: 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 actually split • 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 medium > 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: opus, 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. Add one rule to ~/.claude/CLAUDE.md: consult the advisor before a large plan, when an error repeats, and before calling a long task done. Show me every change as a diff first. No edits until I say go" ↳

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."

holy sh*t. Official Anthropic tip for Claude Code: Once Opus 5.5 is your main model, stop leaving Haiku 5.5 sitting idle and stop burning Opus tokens on sweeps Sonnet 5.5 and Haiku 5.5 can tear through turn mass-agent sweeps into deterministic code with /workflows claude --effort ultracode Opus 5.5 authors the workflow script and synthesizes the final PR Sonnet 5.5 executes precision refactors in isolated worktrees at medium effort Haiku 5.5 runs at 340 tok/s as the dedicated pipeline filter, cutting cognitive load at three critical bottlenecks: → before dispatch: sweeps the full codebase in parallel to extract AST candidates without context bloat → on schema validation: drops malformed tool calls and false positives before Sonnet touches them → before synthesis: verifies that every candidate strictly conforms to the target JSON schema Haiku 5.5 filters. Sonnet 5.5 refactors.
