holy sh*t. Official Anthropic tip for Claude Code: stop burning Opus 5.5 context on tasks Haiku 5.5 can swarm, while Sonnet 5.5 builds
put the architect on call with /advisor
claude --advisor opus --subagents haiku
Sonnet 5.5 drives the primary session on high effort, writing diffs and running test suites
Haiku 5.5 subagents swarm the repo in parallel at 340 tok/s, handling file discovery and spec docs lookup
Opus 5.5 stays on call in the background as the advisor, only stepping in at three critical moments:
→ before a plan locks: does the implementation plan miss auth invariants or schema contracts?
→ when a test breaks twice: are we fixing the root cause or falling into a recursive rabbit hole?
→ before calling done: did the full diff introduce hidden regressions or break pre-flight rules?
Opus 5.5 reviews. Sonnet 5.5 builds. Haiku 5.5 swarms
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 Opus on call.
- the full advisor setup
> Opus 5.5 on call reads full session history and catches deep architectural traps
> Sonnet 5.5 lead drives edits, writes core logic, and executes test harnesses
> Haiku 5.5 subagents swarm AST parsing, grep scans, and API docs in parallel
> JEV micro-fork layer resolves 1,500+ mechanical routing branches in under 16ms
> advisor stays completely silent on routine bash execution to protect context
paste the setup and this prompt into Claude Code below:
"Configure my Claude Code workspace for hierarchical advisor orchestration:
1. Audit ~/.claude/settings.json and project config for model roles fitting lead, subagents, and advisor:
> Pin main session model: sonnet with effortLevel: high for primary execution
> Pin subagents model: haiku with effortLevel: medium for parallel file discovery and docs retrieval
> Pin advisor model: opus on call for strategic review
2. Enable the advisor tool in ~/.claude/settings.json:
> Set advisorModel to claude-opus-5-5
> Enable subagent parallel dispatcher pool (3x workers)
3. Configure automatic advisor consultation checkpoints in ~/.claude/CLAUDE.md:
> Consult /advisor opus before finalizing multi-file architecture plans
> Automatically summon /advisor opus when the same test or compiler error fails twice
> Enforce advisor diff contract audit before declaring tasks complete or staging git commits
4. Constrain subagent scopes:
> Haiku subagents return structured AST summaries and docs snippets only without modifying main session context
Show every configuration diff first. Do not apply edits until confirmed"

@SmokeAwayyy Workaround until it's fixed (uBlock Origin > My filters):
https://t.co/EJ4vQo7xQE##[popover="manual"].contents:style(border:0 !important; padding:0 !important; background:transparent !important;)
Don't add overflow:hidden: the div is 0x0
@SmokeAwayyy Found it: an empty <div popover="manual"> X mounts in the top layer. Its [&:popover-open]:border-0 / p-0 / bg-transparent / m-0 classes aren't in the shipped CSS, so the UA's default popover styling wins: 12px white box centered by margin:auto. X-side CSS bug, not the browser.
7/ Conclusión: Desde los '70, gran parte de los acuerdos con el FMI en 🇦🇷 se han usado para cubrir urgencias y estabilizar mercados, pero a menudo terminaron alimentando ciclos de especulación. ¿El nuevo acuerdo será diferente? Solo el tiempo dirá. #HistoriaArgentina
1/🧵A lo largo de su historia, Argentina ha recurrido al FMI en varias ocasiones. La mayoría de estos acuerdos estuvieron asociados a crisis y ajustes. Hoy repasamos cómo en muchos casos terminaron alimentando ciclos de especulación financiera. ⬇️
6/ 2024 - Actualidad:
El gobierno de Javier Milei negocia otro acuerdo con el FMI. ¿Se aprenderá de los errores pasados o se repetirá el ciclo de especulación?
La clave estará en si se logra una matriz productiva o si solo se estabiliza el tipo de cambio de forma temporal.
