PR: PM Mode as Default - Phase 1 Implementation

Status: ✅ Ready for Review Test Coverage: 26 tests, all passing Breaking Changes: None

📋 Summary

This PR implements Phase 1 of the PM-as-Default architecture: PM Mode Initialization and Validation Infrastructure.

What This Enables

✅ Automatic Context Contract generation (project-specific rules)
✅ Reflexion Memory system (learning from mistakes)
✅ 5 Core Validators (security, dependencies, runtime, tests, contracts)
✅ Foundation for 4-phase workflow (PLANNING/TASKLIST/DO/ACTION)

🎯 Problem Solved

Before

PM Mode was optional and rarely used
No enforcement of project-specific rules (Kong, Infisical, .env禁止)
Same mistakes repeated (no learning system)
No pre-execution validation (implementations broke rules)

After

PM Mode initializes automatically at session start
Context Contract enforces rules before execution
Reflexion Memory prevents recurring mistakes
Validators block problematic code before execution

🏗️ Architecture

1. PM Mode Init Hook

Location: superclaude/core/pm_init/

python

from superclaude.core.pm_init import initialize_pm_mode

# Runs automatically at session start
init_data = initialize_pm_mode()
# Returns: Context Contract + Reflexion Memory + Project Structure

Features:

Git repository detection
Lightweight structure scan (paths only, no content reading)
Context Contract auto-generation
Reflexion Memory loading

2. Context Contract

Location: docs/memory/context-contract.yaml (auto-generated)

Purpose: Enforce project-specific rules

yaml

version: 1.0.0
principles:
  use_infisical_only: true
  no_env_files: true
  outbound_through: kong
runtime:
  node:
    manager: pnpm
    source: lockfile-defined
validators:
  - deps_exist_on_registry
  - tests_must_run
  - no_env_file_creation
  - outbound_through_proxy

Detection Logic:

Infisical → no_env_files: true
Kong → outbound_through: kong
Traefik → outbound_through: traefik
pnpm-lock.yaml → manager: pnpm

3. Reflexion Memory

Location: docs/memory/reflexion.jsonl

Purpose: Learn from mistakes, prevent recurrence

jsonl

{"ts": "2025-10-19T...", "task": "auth", "mistake": "forgot kong routing", "rule": "all services route through kong", "fix": "added kong route", "tests": ["test_kong.py"], "status": "adopted"}

Features:

Add entries: memory.add_entry(ReflexionEntry(...))
Search similar: memory.search_similar_mistakes("kong routing")
Get rules: memory.get_rules()

4. Validators

Location: superclaude/validators/

ContextContractValidator

Enforces project-specific rules
Checks .env file creation (禁止)
Detects hardcoded secrets
Validates Kong/Traefik routing

DependencySanityValidator

Validates package.json/pyproject.toml
Checks package name format
Detects version inconsistencies

RuntimePolicyValidator

Validates Node.js/Python versions
Checks engine specifications
Ensures lockfile consistency

TestRunnerValidator

Detects test files in changes
Runs tests automatically
Fails if tests don't pass

SecurityRoughcheckValidator

Detects hardcoded secrets (Stripe, Supabase, OpenAI, Infisical)
Blocks .env file creation
Warns on unsafe patterns (eval, exec, shell=True)

📊 Test Coverage

Total: 26 tests, all passing

PM Init Tests (11 tests)

✅ Git repository detection
✅ Structure scanning
✅ Context Contract generation (Infisical, Kong, Traefik)
✅ Runtime detection (Node, Python, pnpm, uv)
✅ Reflexion Memory (load, add, search)

Validator Tests (15 tests)

✅ Context Contract validation
✅ Dependency sanity checks
✅ Runtime policy validation
✅ Security roughcheck (secrets, .env, unsafe patterns)
✅ Validator chain (all pass, early stop)

# Run tests

🚀 Usage

Automatic Initialization

python

# Session start (automatic)
from superclaude.core.pm_init import initialize_pm_mode

init_data = initialize_pm_mode()

# Returns
{
    "status": "initialized",
    "git_root": "/path/to/repo",
    "structure": {...},  # Docker, Infra, Package managers
    "context_contract": {...},  # Project-specific rules
    "reflexion_memory": {
        "total_entries": 5,
        "rules": ["all services route through kong", ...],
        "recent_mistakes": [...]
    }
}

Manual Validation

python

from superclaude.validators import (
    ContextContractValidator,
    SecurityRoughcheckValidator,
    ValidationStatus
)

# Create validator
validator = SecurityRoughcheckValidator()

# Validate changes
result = validator.validate({
    "changes": {
        ".env": "SECRET_KEY=abc123"
    }
})

# Check result
if result.failed:
    print(result.message)  # "CRITICAL security issues detected"
    print(result.details)  # {"critical": ["❌ .env file detected"]}
    print(result.suggestions)  # ["Remove hardcoded secrets", ...]

Reflexion Memory

python

from superclaude.core.pm_init import ReflexionMemory, ReflexionEntry

memory = ReflexionMemory(git_root)

# Add entry
entry = ReflexionEntry(
    task="auth implementation",
    mistake="forgot kong routing",
    evidence="direct connection detected",
    rule="all services must route through kong",
    fix="added kong service in docker-compose.yml",
    tests=["test_kong_routing.py"]
)
memory.add_entry(entry)

# Search similar mistakes
similar = memory.search_similar_mistakes("kong routing missing")
# Returns: List[ReflexionEntry] with similar past mistakes

# Get all rules
rules = memory.get_rules()
# Returns: ["all services must route through kong", ...]
