[Bug] /effort shows "Ultracode needs dynamic workflows enabled" even when dynamic workflows are on

Bug Description

/effort displays the warning:

Ultracode needs dynamic workflows enabled (see /config) and an xhigh-capable model. Valid options are: low, medium, high, xhigh, max, auto

...even when:

1. Dynamic workflows are enabled in /config (shows as true/on)
2. Model is Opus 4.6 (xhigh-capable)
3. effortLevel: "xhigh" is persisted in ~/.claude/settings.json

Running /config confirms dynamic workflows = on. Running /config dynamic workflows outputs "Set workflows to on". But /effort still shows the warning and does not activate ultracode.

Steps to Reproduce

1. /config → enable dynamic workflows → confirm it shows "on"
2. /model claude-opus-4-6
3. /effort → observe warning message instead of effort level options
4. /config dynamic workflows → confirms "Set workflows to on"

Expected Behavior

/effort should recognize that dynamic workflows are enabled and allow setting xhigh/max/ultracode effort levels.

Actual Behavior

/effort always shows the "needs dynamic workflows enabled" warning regardless of the /config setting. The gate check in /effort appears to read from a different source than where /config writes the dynamic workflows toggle.

Environment Info

• Claude Code version: 2.1.156
• Platform: macOS (darwin, Darwin 25.2.0)
• Model: claude-opus-4-6
• Settings: effortLevel: "xhigh" in ~/.claude/settings.json

Related Issues

• #63468 — statusline reports "xhigh" instead of "ultra" for ultracode (adjacent but distinct: that's about statusline reporting, this is about the /effort activation gate)
