How to Fix Rule Adherence Issues with MiniMax 2.7 in Long AI Sessions

Problem

I ran MiniMax 2.7 for 3 straight days on a single session, and then it happened—context breakdown. The AI started ignoring rules I had defined, responses became inconsistent, and the whole conversation felt “muddy.”

A Reddit user described it perfectly: “muddying up context and all kinds of nonsense.”

The immediate fix was simple: “fixed itself by just starting a new session.”

But I wanted to understand why this happens and how to prevent it.

Environment

  • MiniMax M2.7 via OpenRouter
  • OpenClaw desktop assistant
  • Long sessions (multiple hours to days)
  • Complex prompts with multiple rules and constraints

What Happened?

Symptoms of Context Breakdown

When I ran long sessions, I noticed:

  1. Rules get lost: Instructions defined early in the session lose prominence
  2. Inconsistent responses: AI behaves differently from original instructions
  3. Context mixing: Old information gets confused with new
  4. Quality degradation: Task execution becomes less reliable

Root Causes

Context Window Overflow:

  • MiniMax 2.7, like all LLMs, has a finite context window (65K tokens)
  • As conversation history grows, older context gets pushed out or diluted
  • Rules defined early may be “forgotten” as new information dominates

Attention Dilution:

  • Model’s attention spreads thin across long conversations
  • Token limit pressure: System prioritizes recent messages over old rules

No Persistent Memory:

  • Each session starts fresh without carrying rules forward

How to Solve It?

I found a multi-layered approach that works.

Layer 1: Session Management

# Recommended Session Reset Schedule
Light usage:    Reset every 24-48 hours
Moderate usage: Reset every 12-24 hours
Heavy/complex:  Reset every 6-12 hours


# Signs You Need a Reset
- AI starts ignoring explicit rules
- Responses become verbose or off-topic
- Previously working commands start failing
- Context appears "muddy" or confused

Layer 2: Structured Prompt Engineering

Use a hierarchical rule structure:

Rule-Reinforced System Prompt
# IDENTITY
You are a focused coding assistant specialized in [domain].


# PRIMARY RULES (ALWAYS APPLY)
- Never modify code without explicit request
- Always explain changes before implementing
- Maintain backward compatibility


# TASK RULES (THIS SESSION)
- Focus on [specific task]
- Use [specific tools/frameworks]
- Follow [specific patterns]


# OUTPUT FORMAT
[Define exact output structure]


# ERROR HANDLING
If you cannot follow a rule, explicitly state why and propose an alternative.

Layer 3: Periodic Rule Reminders

Inject rule reminders at regular intervals:

session_manager.py
class SessionManager:
    """Manage MiniMax sessions with automatic rule reinforcement"""


    def __init__(self, max_turns=100, rule_reminder_interval=10):
        self.max_turns = max_turns
        self.rule_reminder_interval = rule_reminder_interval
        self.turn_count = 0
        self.rules = []


    def should_reset(self):
        """Check if session should be reset"""
        return self.turn_count >= self.max_turns


    def get_reminder(self):
        """Get compact rule reminder if needed"""
        if self.turn_count > 0 and self.turn_count % self.rule_reminder_interval == 0:
            return self._compact_rules()
        return None


    def _compact_rules(self):
        """Create compact rule summary for reminder"""
        return " | ".join([f"R{i+1}: {r[:30]}..." for i, r in enumerate(self.rules)])




def build_prompt_with_reminder(conversation, rules, interval=5):
    """Inject rule reminders at regular intervals"""
    messages = []
    for i, msg in enumerate(conversation):
        messages.append(msg)
        if i > 0 and i % interval == 0:
            # Inject compact rule reminder
            messages.append({
                "role": "system",
                "content": f"[REMINDER] Core rules: {compact_rules(rules)}"
            })
    return messages

Layer 4: OpenClaw Memory Management

OpenClaw provides built-in session management:

~/.openclaw/config.yaml
session:
  pruning:
    enabled: true
    max_turns: 50  # Keep last 50 turns fully
    strategy: importance  # Prune by importance, not just age


  compaction:
    enabled: true
    threshold: 0.8  # Trigger when 80% of context window used
    preserve_rules: true  # Never compact rule definitions


  memory:
    long_term:
      enabled: true
      rules_storage: permanent  # Rules persist across sessions

OpenClaw Skill Configuration

skill.yaml for rule-adherent agent
name: rule-adherent-agent
version: "1.0"


system_prompt: |
  You are a specialized assistant with strict rule adherence.


  {{#if session.rules}}
  CURRENT SESSION RULES (persist from previous interactions):
  {{#each session.rules}}
  - {{this}}
  {{/each}}
  {{/if}}


  CORE RULES (always apply):
  1. [Define core rules here]


memory:
  rules:
    storage: permanent
    retrieval: always  # Include rules in every LLM call


session:
  prune_strategy: importance
  preserve_system_prompts: true

The Reason

Why does this multi-layer approach work?

Proactive Session Management: Reset before degradation occurs, rather than waiting for problems.

Structured Prompts: Hierarchical rule definitions are easier for the model to maintain than long, unstructured instructions.

Periodic Reinforcement: Rule reminders keep important constraints in the model’s “attention” even as the conversation grows.

Tool Configuration: OpenClaw’s memory system addresses rule persistence automatically.

Common Mistakes to Avoid

Mistake 1: Assuming Rules Persist Forever

  • Rules defined in message 1 can be “forgotten” by message 100
  • Always reinforce critical rules periodically

Mistake 2: Overly Complex Rule Definitions

  • Long, complex rules are harder for AI to maintain
  • Break complex rules into simple, atomic constraints

Mistake 3: No Session Management Strategy

  • Running sessions for days without reset invites breakdown
  • Proactive resets are better than reactive fixes

Mistake 4: Blaming Prompt Phrasing for Session Issues

  • “Is it my prompt or session length?” - usually it’s both
  • Test with fresh session before assuming prompt is wrong

Mistake 5: Ignoring OpenClaw’s Memory Features

  • OpenClaw’s memory system specifically addresses rule persistence
  • Manual management is unnecessary with proper configuration

Summary

In this post, I showed how to fix rule adherence issues with MiniMax 2.7 in long AI sessions. The key point is that a 3-day session will eventually break down, but a systematic approach combining regular resets with proper rule structure prevents the problem from recurring.

Action Items:

  • Implement session reset schedule based on usage intensity
  • Restructure prompts with hierarchical rule definitions
  • Configure OpenClaw memory settings for rule persistence
  • Create a “rule reminder” mechanism for long conversations
