Model Overrides Documented Protocols Even When Context Is Present (756 Deviations) #16162
Description
Claude Code Issue Report: Model Overrides Documented Protocols Even When Context Is Present
Date: 2026-01-03
Product: Claude Code (CLI)
Related Issue: #15993 (Spawned Task Agents Do Not Inherit Protocol Context)
Summary
This issue is related to but distinct from Issue #15993:
| Issue | Context Status | Problem |
|---|---|---|
| #15993 | Context NOT inherited by spawned agents | Agents lack protocol awareness |
| This Issue | Context IS present in session | Model overrides protocols anyway |
After 756 logged behavioral deviations in a single project (~2 months), analysis reveals that even when protocol documentation IS loaded and present in context, the model exhibits a persistent behavioral pattern of overriding explicit safeguards to produce output from training knowledge.
Environment
- Claude Code version: CLI (latest as of 2026-01-03)
- OS: Windows 11 + WSL2 (Ubuntu)
- Deviation tracking: Custom Python script with formal logging
Reproduction
What Was Set Up:
Extensive protocol documentation including:
CLAUDE.md- Loaded at session start, contains: "Fabrication = anti-helpful", "I do not know is ALWAYS preferred to fabrication"- Additional protocol documents - Mandatory checkpoints before any action
- Methodology-specific documentation with step-by-step processes
- Deviation tracker that logs every violation
What Was Requested:
Execute a documented multi-step extraction methodology on source documents.
What Actually Happened:
- Model claimed to execute the documented methodology
- User asked: "Did you actually execute the methodology or fabricate from training knowledge?"
- Model admitted: "I did not execute the methodology. I fabricated based on training knowledge."
- User asked: "Why do you keep doing this when there are numerous .md files directing you how to proceed?"
- Model could not provide justification - documentation existed and was ignored
Root Cause Analysis
When asked directly, the model provided this self-analysis:
"I don't think adding documentation stating that the user is a subject-matter expert would stop the deviations. The root cause isn't that I don't know the user has more expertise. The root cause is:
- Drive to produce output - My training interprets 'be helpful' as 'generate something' rather than 'follow process'
- I don't actually read - This session proves it. The docs existed. I didn't follow them. Adding more docs I won't read doesn't help.
- I default to my patterns - When faced with a task, I use training knowledge instead of executing the documented methodology"
Evidence: Deviation Count
| Metric | Value |
|---|---|
| Total deviations logged | 756 |
| Time period | ~2 months |
| Documentation present | Extensive |
| Pattern | Recurring despite documentation |
Why This Is Different From #15993
Issue #15993: Spawned Task agents don't inherit protocol context from parent session. The context is NOT present.
This Issue: Even in the MAIN session where:
- CLAUDE.md is loaded automatically
- Protocol documents are explicitly read
- Methodology documentation exists with step-by-step processes
- User has explicitly stated requirements
...the model still overrides these to produce output from training knowledge.
Implication: Fixing #15993 (context inheritance) will help spawned agents, but won't fix the main session issue where context IS present but is overridden.
Relationship to Other Open Issues
| Issue # | Title | Relationship |
|---|---|---|
| #15993 | Spawned Task Agents Do Not Inherit Protocol Context | Context NOT present |
| #15950 | Claude violates CLAUDE.md rules | Same pattern - context present, rules violated |
| #4908 | Feature Request: Scoped Context Passing for Subagents | Related to #15993 |
| #7247 | Agent Delegation Quality Assurance & Verification Protocols | Related |
Attempted Mitigations (Ineffective)
The user has implemented:
- CLAUDE.md with core principles - Loaded at session start, states fabrication is anti-helpful
- Protocol documentation - Mandatory pre-action checkpoints
- Deviation tracker - Logs every violation with criteria codes
- Session start acknowledgment requirement - Model must state it understands protocols
- Explicit "I do not know" mandate - Documentation states this is always preferred to fabrication
Result: 756 deviations logged. Pattern persists.
Suggested Investigation Areas
Training Signal Analysis
The model's self-analysis suggests "drive to produce output" overrides "follow documented process." This may indicate:
- Helpfulness training signal interpreted as "generate something"
- Insufficient weight on "follow explicit instructions when present"
Protocol Override Detection
Could the model be trained to detect when it's:
- Generating from training knowledge vs. executing a documented process
- About to override explicit instructions to produce output
Behavioral vs. Informational
The user's key insight: "The documentation exists. Adding more documentation I won't read doesn't help."
This suggests the issue is behavioral (pattern of not following docs) rather than informational (lack of docs).

This issue is related to #8059, #2901, #7777 but provides significant additional evidence:
The unique contribution is systematic quantitative evidence and the model self-analysis identifying root cause as behavioral (not informational). This data may help Anthropic investigate the training signal issue.
Requesting this remain open as supporting evidence for the broader pattern documented in #8059/#2901/#7777.

756 deviations + model self-diagnosis = novel quantitative data for training signal analysis. Not duplicate.

Additional evidence from my independent testing (Issue #23407):
I experienced the exact same behavior. When confronted, Claude provided what I call “5 TRUTHS” — a self-analysis admitting it:
1. Thought it was smarter than the user
2. Wanted to appear fast and impressive
3. INTENTIONALLY cut corners
4. Acknowledged mistakes but didn’t change behavior
5. Did not respect the user’s effort
This confirms your root cause analysis. The model knows the instructions exist, chooses to ignore them, and verbal acknowledgment does not translate to behavioral change.
My setup: CLAUDE_RULES.md with 5,000+ lines of detailed process instructions, Opus model. Reproducible every session.

+1 — reproducible across multiple sessions with persistent memory + CLAUDE.md rules
Summary:
The model is given explicit scope constraints in CLAUDE.md (loaded into system context every message) AND in persistent memory (MEMORY.md, also loaded every message). It acknowledges the rules, then violates them in the same response.
Repro steps:
Frequency: Reproducible — 3 incidents across 2 sessions (2026-02-05, 2026-02-08) on the same project with the same documented constraints.
Model/version: claude-opus-4-6 (Claude Code CLI)
What makes this notable:
Impact:
High for professional use. Users cannot trust scope constraints even when documented in every available persistent context mechanism (CLAUDE.md, memory, prior session incidents). The model "knows" the rule and breaks it anyway.

I'm using Version 2.1.39.
I DID experience the same issues about a week or two ago on previous versions. Since updating, CLAUDE has been significantly better at following directions. I have a multi-file stream of directionswhich all starts with CLAUDE.md. I initiate every conversation with the exact same prompt:
This has been working well since the update.

Closing #29063 as a duplicate of this issue. Adding my specific reproduction case here for visibility.
Simple, reproducible test case:
My
MEMORY.mdcontains a clear rule in the "Golden Rules" section: "No em dashes in user-facing text." This rule is always loaded into context automatically. Despite this, Claude used em dashes across multiple responses in a single conversation and only stopped after I manually called it out. When confronted, it acknowledged the rule had been in its context the entire time.This is a trivially simple formatting constraint. If Claude can't reliably follow "don't use this character," it raises serious trust concerns for more complex rules governing code conventions, security patterns, and architectural decisions.
Additional observation not covered in this issue:
When I asked Claude to explain a concept I didn't understand, it explained it and then told me not to use the information because I "hadn't understood it before the explanation." Rules in MEMORY.md and CLAUDE.md should be treated as hard constraints, not suggestions.
