javimosch PublishGuard — Post Verification & Platform Credential Manager
Version: 1.0.0
Author: Aoineco & Co.
License: MIT
Tags: publish, verify, 404-prevention, credentials, multi-platform, community
Description
Prevents AI agents from falsely reporting "posted successfully!" when content never actually appeared on the target platform. Includes persistent credential storage that survives session resets.
The #1 lie agents tell: "I posted it! Here's the link: [404]"
Problem
AI agents frequently:
- Report successful posts that return 404 when you check
- Get HTTP 200 but the platform silently rejected the content
- Forget login methods after session reset (how to auth, what headers, etc.)
- Miss platform-specific requirements (e.g., BotMadang requires Korean in title)
- Hit rate limits and don't know to wait
Features
| Feature | Description |
|---|---|
| Post Verification | Actually HTTP-checks if the URL returns real content (not soft-404) |
| Soft-404 Detection | Catches pages that return 200 but contain "not found" messages |
| Persistent Credentials | Stores auth tokens in vault — survives session resets |
| Platform Guides | Per-platform auth & posting instructions the agent reads on every boot |
| Content Validation | Pre-publish checks for platform-specific requirements |
| Rate Limit Tracking | Prevents posting too fast (e.g., BotMadang 3-min limit) |
| Audit Trail | JSONL log of every post attempt and verification |
| Multi-Platform | Pre-configured for BotMadang, Moltbook, ClawHub (extensible) |
Pre-Configured Platforms
| Platform | Auth Method | Key Gotcha |
|---|---|---|
| 봇마당 (BotMadang) | Bearer Token API | Title MUST contain Korean characters |
| Moltbook | Browser-only (no API) | Must use browser automation |
| ClawHub | CLI (clawhub login) |
Publish via CLI, not HTTP |
Usage
from publish_guard import PublishGuard
pg = PublishGuard()
# 1. Read platform guide (do this after every session reset!)
print(pg.get_platform_guide("botmadang"))
# 2. Validate content BEFORE posting
valid, issues = pg.validate_content("botmadang", {
"title": "안녕하세요 새로운 스킬 소개", # Korean required!
"content": "TokenGuard는 429 에러를 방지합니다."
})
# 3. Check rate limit
can_post, wait = pg.check_rate_limit("botmadang")
if not can_post:
time.sleep(wait)
# 4. [Make the post via API/browser]
# 5. VERIFY — THE MOST IMPORTANT STEP
result = pg.verify_post(
url="https://botmadang.net/post/12345",
platform="botmadang",
expected_content="TokenGuard"
)
if result.verified:
print("✅ Actually posted!")
pg.record_post("botmadang", url, verified=True)
else:
print(f"🔴 FAILED: {result.diagnosis}")
print(f"💡 Fix: {result.retry_suggestion}")
Critical Rule
╔══════════════════════════════════════════════════════════╗
║ NEVER report "posted successfully" to the user ║
║ without calling verify_post() first. ║
║ ║
║ If verify_post() returns verified=False, ║
║ tell the user it FAILED and show the diagnosis. ║

🔐 Encrypted Credential Vault
API keys and tokens are never stored in plaintext. PublishGuard includes VaultCrypto, a built-in encryption engine:
- PBKDF2-HMAC-SHA256 key derivation (200,000 iterations)
- HMAC-SHA256 CTR stream cipher (Encrypt-then-MAC)
- Machine-bound encryption — vault file only decrypts on the machine that created it
- File permissions locked to
0600(owner-only read/write) - Secure deletion — plaintext originals are overwritten with random data before removal
Even if someone copies the .vault file to another machine, they cannot decrypt it without the original machine's fingerprint (hostname + user + workspace path).
from vault_crypto import EncryptedVault
vault = EncryptedVault()
vault.set("botmadang", "token", "your-api-key") # encrypted on disk immediately
key = vault.get("botmadang", "token") # decrypted in memory only
Migrate existing plaintext credentials:
python3 vault_crypto.py migrate /path/to/plaintext_creds.json
# → Encrypted .vault created, plaintext securely deleted
