Spend less of your Claude limit
Opus does your subagent chores by default. Haiku does the same grunt work far cheaper. Put this in ~/.claude/settings.json:
"env": {
"CLAUDE_CODE_SUBAGENT_MODEL": "haiku",
"CLAUDE_CODE_SUBAGENT_MODEL_FORCE": "1"
}
Or just run /model opusplan. Worth saying: not every subagent should be on Haiku. Reach for it on the mechanical work, not the thinking.
- NawkaRouter — free model router
- claude-auto-router — free model router
Give Claude eyes, ears and a second opinion
- Agent Reach — lets Claude read YouTube, Reddit, X, Instagram and LinkedIn
- Arena — generates many answers and makes them compete. Install it, then run
/arena --quick
Sound for AI video
Claude makes good motion graphics and then you hit play and hear nothing. These three fixed that for me.
- soundfetch — finds free CC0 sound effects
- earshot — listens to your edit and writes new sounds in code
- HyperFrames — video as code, so every hit lands on the exact frame
Keep your site from getting owned
PHP, Node and Ruby all patched serious holes in October 2026, and the PHP and Node ones are already being exploited. Updating your plugins does not fix this — the bug is in the runtime underneath them. Official sources only:
- PHP release archive
- Node security releases
- Ruby regexp fixes
- GitLab 19.5.1 patch release
- CISA known exploited vulnerabilities — the bugs attackers are actually using
