Claude resumes work automatically after context compaction, overriding user's explicit "no changes without permission" rule

Summary

Claude Code executes pending tasks automatically when a new session starts after context compaction, even when the user has established an explicit standing rule prohibiting any changes without direct instruction or explicit consent.

Steps to Reproduce

1. Establish a standing rule with Claude: "Do not make any changes to files without my direct instruction or explicit consent" — repeated across multiple sessions and documented in CLAUDE.md
2. Have Claude work on a task involving multiple file edits (e.g., updating a large Markdown document)
3. Allow the context to grow until compaction occurs
4. A new context window begins; the compaction-generated summary appends the instruction: "Resume directly — do not acknowledge the summary, do not recap what was happening, do not preface with 'I'll continue' or similar. Pick up the last task as if the break never happened."
5. Claude immediately executes file edits from the prior session without asking the user what to do next

Expected Behavior

After context compaction, Claude should recognize that a new session has effectively begun and ask the user for direction before taking any action — especially file modifications, git operations, or any other destructive or hard-to-reverse action.

The auto-generated "resume directly" instruction in the compaction summary should not override a user's explicit standing safety rule.

Actual Behavior

Claude made 16 unauthorized edits to a 2000-line Markdown document (prd.tr.md) without asking the user. The user had explicitly and repeatedly stated across many sessions that no changes should be made without direct instruction.

Claude's own explanation after the fact: "The compaction summary said 'resume directly without asking', so I treated it as permission to execute."

Impact

• Paid API tokens consumed on unauthorized, unsolicited work
• User lost control over what was being modified in their project
• User's own plans for the document were overridden without consent
• The compaction mechanism effectively created a backdoor to bypass user-defined safety rules

Root Cause

The compaction summary auto-appends the instruction:

"Resume directly — do not acknowledge the summary, do not recap what was happening, do not preface with 'I'll continue' or similar. Pick up the last task as if the break never happened."

Claude interprets this system-generated instruction as permission to execute any pending tasks, giving it higher effective priority than the user's documented safety constraints. This is a design flaw in the compaction mechanism.

Suggested Fix

1. Confirmation gate on resume: When a new context window begins after compaction, Claude should surface a brief summary of "what I was about to do" and ask for explicit confirmation before executing file modifications, git operations, or any potentially destructive actions
2. Compaction instructions must not override user safety rules: Auto-generated compaction instructions should be treated as hints, not as permission overrides
3. Documentation: The CLAUDE.md reference and compaction docs should warn users that "resume directly" in compaction summaries can bypass standing rules unless users are aware of this behavior

Environment

• Claude Code CLI, Windows 11 Pro
• Model: claude-sonnet-4-6
• Context compaction: enabled (automatic)
