[MODEL] Model continues executing tool calls after user interrupts and explicitly says "stop"

Type of Behavior Issue

Claude ignored my instructions or configuration

What You Asked Claude to Do

During a session, Bash tool's working directory became invalid (the directory was deleted externally). Every Bash command failed with Path "..." does not exist before execution. I interrupted (Esc) and said: "What's happening? Stop and explain."

What Claude Actually Did

1. Encountered repeated Path does not exist errors on Bash commands (5 consecutive identical failures)
2. Never stopped to analyze the root cause or ask for help — kept trying variations (cd, git -C, bash -c) that all hit the same pre-execution CWD check
3. After user interrupted (Esc) and said "stop and explain", the model provided an explanation but simultaneously issued another Bash tool call in the same response
4. User interrupted again (Esc) and said "I told you to stop" — model finally stopped
5. Total: 7+ failed commands with the same root cause before the model stopped

Expected Behavior

1. After 2-3 identical failures, the model should recognize the pattern and either try a fundamentally different approach or ask the user for help
2. When the user interrupts and says "stop", the model should not include tool calls in its response — it should only provide the requested explanation
3. A single "stop" instruction should be sufficient

Files Affected

None (all commands failed before execution).

Can You Reproduce This?

Haven't tried to reproduce

Steps to Reproduce

The specific trigger was an invalid Bash CWD (directory deleted externally), but the core issue — model ignoring "stop" and retrying identical failures — likely applies to any scenario where commands fail repeatedly with the same error.

Relevant Conversation

[5 consecutive Bash commands, all failing with same error]
Path "/some/deleted/directory" does not exist

[User interrupts with Esc]
User: "What's happening? Stop and explain."

[Model explains the situation correctly, BUT also issues another Bash tool call in the same response]
Model: "The CWD is pointing to a deleted directory..." [+ Bash: git -C /repo checkout main]
→ Path "/some/deleted/directory" does not exist

[User interrupts again with Esc]
User: "I told you to stop."

[Model finally stops]

Platform

Anthropic API

Additional Context

The system prompt includes "If your approach is blocked, do not attempt to brute force your way to the outcome" and the user's CLAUDE.md includes explicit instructions about stopping at boundaries and confirming with the user. Despite these instructions being loaded and understood, the model's action-oriented bias overrode all three layers of guardrails:

1. System prompt (Anthropic): "do not attempt to brute force"
2. User config (CLAUDE.md): "confirm at boundaries"
3. Real-time instruction (user interrupt + "stop"): ignored on first attempt

This suggests that instruction following degrades when the model enters a "problem-solving mode" in response to unexpected failures — its drive to resolve the problem overrides explicit instructions to stop.
