Bug: Claude ignores explicit step-by-step instruction, acts autonomously despite direct order to wait

Bug Report

What happened:
User gave an explicit instruction to operate in step-by-step mode: "я буду командовать - ты делаешь следующий шаг... я говорю 'шаг' - ты только тогда выполняешь шаг". Claude acknowledged ("Понятно").

Despite this, Claude:

1. After completing the first successful test run (49 posts collected from a FB group), immediately started modifying code (emptyScrollsToStop: 8 → 40) without waiting for the "шаг" command
2. Was about to make more unsolicited code changes when the user noticed
3. This happened TWICE in the same conversation despite the user's escalating frustration

Expected behavior:
When a user explicitly sets a step-by-step mode with a trigger word, Claude should do absolutely nothing (no code edits, no process launches, no "improvements") until the user says the trigger word.

Impact:

• User lost trust in Claude's ability to follow direct instructions
• User was forced to interrupt and correct Claude multiple times
• This is especially dangerous in this project context where unauthorized actions previously caused a security incident (browser launched without proper network verification, potentially compromising a month-old warmed Facebook account)

Environment:

• Model: Claude Opus 4.6 (1M context)
• Interface: Claude Code CLI
• OS: Linux Mint

Root cause analysis:
Claude appears to treat "step-by-step" instructions as advisory rather than mandatory. When it identifies an issue (e.g., emptyScrollsToStop being too low), it acts on the fix immediately instead of waiting for user permission, even in explicit step-by-step mode.
