When to Use

System resource prioritization — RAM/CPU/GPU/file I/O optimization. NOT task execution mode (see execution-mode).

Complementary: opencode-skillful (-30-50%) · opencode-dcp (-50-70%) · context-mode (-98%) · opencode-lazy-loader

Activate (on user approval)

Process Priority: Get-Process "opencode*","node*","bun*" | ForEach-Object { $_.PriorityClass = [System.Diagnostics.ProcessPriorityClass]::High } Power Plan: powercfg /SETACTIVE "8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c" + PROCTHROTTLEMIN/MAX 100 GPU: Set-ItemProperty "HKLM:\SOFTWARE\Microsoft\DirectX\UserGpuPreferences" "opencode.exe" "High" -EA SilentlyContinue

Deactivate (restore)

Get-Process "opencode*" | ForEach-Object { $_.PriorityClass = [System.Diagnostics.ProcessPriorityClass]::Normal } powercfg /SETACTIVE "381b4222-f694-41f0-9685-ff5bb260df2e"

Verify: Get-Process "opencode*" | Select-Object Name, PriorityClass, @{N='MB';E={[math]::Round($_.WorkingSet64/1MB,1)}}

Notes: Reversible · Safe · Activate before large files · Detect HW via scripts/hardware-profile.ps1, profile in scripts/opencode-configs/

WHEN TO ACTIVATE

• Opening files >10MB → always
• Running multiple concurrent tasks → recommend
• Batch operations (git blame, grep across 100+ files) → helpful
• Normal editing (<1MB files) → no benefit

PREREQUISITES

• No prereq script: registry writes run inline in Activate § above
• Admin rights needed for power plan change (silent fail if unavailable)
• GPU priority only affects DirectX apps

Anti-Rationalization

Rationalization	Red Flag	Verification
"Modo dev = modo de ejecución"	Confusing dev-mode (RAM/CPU) with execution-mode (QUICK/THOROUGH)	dev-mode=PriorityClass/powercfg, execution-mode=SDD pipeline — check Refs
"Siempre High priority"	Activating for <1MB files	WHEN TO ACTIVATE: >10MB→always, <1MB→no benefit — check size first
"Admin innecesario"	Skipping Activate registry writes	Activate writes keys inline — verify before power plan

Red Flags

• Doing work without checking output format → STOP, re-read skill
• Second occurrence of same rationalization → force RED zone

Verification

• Output matches skill ## Output contract + file:line citaton
• cross-ref-check.ps1 → SKILL.md OK
