# AI Monitoring — Design Specification
> **Codex Launcher v3.8.0 Feature Design**
> Self-healing nano agent that monitors proxy health, diagnoses failures, and auto-recovers sessions.
---
## 1. Problem Statement
Over 42 sessions in production, we observed these failure categories:
| # | Failure Category | Count | Example |
|---|-----------------|-------|---------|
| F1 | **parsed_tool_calls=0** — model produces unparseable output | 42 | Bare `<explore_agent>`, `<bash>` without cmd, plain English intent |
| F2 | **Stuck recovery triggered** — Intelligence Routing Layer 3 | 13 | "I need to fetch the README", "let me write the script" |
| F3 | **Sanitizer flagged suspicious cmd** — cmd still JSON after unwrap | 11 | `{/'cmd/': /'sshpass -p .../'}` — double-escaped quoting |
| F4 | **Upstream 500** — provider internal error | ~5 | `"An internal error occurred. Please try again later."` |
| F5 | **Connection timeout** — upstream unreachable | ~3 | `Connection timed out after 15002 milliseconds` |
| F6 | **Upstream 401/403** — auth failure | ~2 | Wrong API key, expired token, `upgrade_required` |
| F7 | **Stream crash** — exception mid-stream | ~2 | `BrokenPipeError`, `ConnectionResetError` during SSE |
| F8 | **Proxy port conflict** — Address already in use | ~1 | Stale process holding port |
| F9 | **Schema cache corruption** — stale content_type=array | ~1 | `ErrorAnalyzer` learned wrong schema |
| F10 | **Codex Desktop crash** — SIGKILL at ~27GB | ~1 | Issue #24048 — unbounded tool output memory |
| F11 | **Codex 300s stall** — turn state machine race | ~1 | Issue #23807 — `stream disconnected` after 300s |
### The Gap
Intelligence Routing (v3.7.0) handles F1/F2/F3 **inside a single request**. But it can't:
- **Detect a dead proxy process** (F7/F8) — the proxy already crashed
- **Reconnect Codex to a restarted proxy** (F5/F7/F8) — Codex doesn't auto-reconnect
- **Switch to a backup provider** when the primary is down (F4/F5)
- **Clear corrupt caches** (F9) — requires out-of-band action
- **Restart Codex Desktop** after a crash (F10/F11)
- **Learn from failure patterns** across sessions — each failure is handled independently
### What We Need
A **separate lightweight watchdog process** that:
1. Monitors proxy health continuously
2. Detects failures the proxy can't detect itself
3. Uses a cheap AI model to diagnose novel failures
4. Takes corrective action automatically
5. Learns from past incidents to prevent repeats

## 3. Three-Tier Response System
### Tier 1: Fast Path — Rule-Based Auto-Recovery (< 1 second)
Immediate reactions to **known failure patterns**. No AI needed.
```python
TIER1_RULES = [
# (trigger_pattern, action, cooldown)
# --- Proxy Health ---
("proxy_health_fail", "restart_proxy", 30),
("proxy_port_conflict", "kill_stale + restart", 60),
("proxy_memory_over_1gb", "restart_proxy", 120),
# --- Upstream Errors ---
("upstream_429", "wait_retry_after", 0),
("upstream_502_503", "retry_with_backoff", 30),
("upstream_500_repeat_3x", "switch_provider", 60),
("upstream_timeout", "retry + increase_timeout", 30),
("upstream_401_403", "alert_user_bad_key", 0),
# --- Stream Errors ---
("stream_broken_pipe", "restart_proxy", 30),
("stream_reset", "restart_proxy", 30),
("stream_idle_300s", "restart_proxy", 60),
# --- Parser Failures ---
("parsed_tool_calls_0_x3", "clear_schema_cache", 300),
("sanitizer_suspicious_5x","alert_user_model_issue", 0),
("stuck_recovery_x5", "suggest_switch_model", 0),
# --- Codex Process ---
("codex_process_dead", "alert_user_restart", 0),
("codex_memory_over_4gb", "alert_user_memory", 0),
# --- Cache Corruption ---
("schema_content_type_array", "delete_provider_caps", 0),
]
```
### Tier 2: Pattern Matching — Incident Store Lookup (< 100ms)
For failures we've **seen before and resolved**, look up the fix:
```json
{
"incidents": [
{
"pattern": "cc_stream_ended_empty + explore_agent + no_url",
"fix": "synth_explore_from_last_user_urls",
"source": "FIX-23",
"success_rate": 0.85,
"last_seen": "2026-05-22T16:00:00Z",
"occurrences": 5
},
{
"pattern": "require_escalation + no_cmd",
"fix": "auto_proceed_echo",
"source": "FIX-24",
"success_rate": 1.0,
"last_seen": "2026-05-22T15:30:00Z",
"occurrences": 3
}
]
}
```
### Tier 3: AI Diagnostic — Nano Agent (2-5 seconds)
For **novel failures** that don't match any rule or pattern, invoke a cheap AI model:
```
Prompt Template (system):
─────────────────────
You are a diagnostic agent for a translation proxy that sits between
OpenAI Codex CLI/Desktop and AI providers (Command Code, OpenAI-compat,
Anthropic, etc.). You analyze error context and suggest ONE corrective action.
Available actions: restart_proxy, kill_stale_processes, clear_schema_cache,
switch_provider, increase_timeout, alert_user, ignore, retry_now,
regenerate_config, cleanup_codex_stale
Respond with ONLY a JSON object: {"action": "...", "reason": "...", "confidence": 0.0-1.0}
Prompt Template (user):
─────────────────────
INCIDENT REPORT:
Time: {timestamp}
Session: {session_id}
Proxy health: {alive/dead, port, uptime, memory_mb}
Upstream: {url, model, last_http_code, last_error}
Recent errors (last 60s):
{log_lines}
Parser state: {parsed_tool_calls, stuck_recovery_count, sanitizer_flags}
Provider: {backend_type, model}
History: {last_5_incidents_for_this_pattern}
What corrective action should be taken?
```

| C1 | Bare `<explore_agent>` | `parsed_tool_calls=0` | Layer 1: URL extraction | If 3x in a row → suggest model switch |
| C2 | `<require_escalation>` block | Model wants permissions | Layer 2: Auto-proceed | If 5x → suggest different provider |
| C3 | Unrecognized format | No parser matches | Layer 3: Intent synthesis | If 5x → log for AI diagnosis |
| C4 | Double-wrapped cmd | `cmd = "{\"cmd\": ...}"` | Sanitizer: unwrap | If cmd still JSON → alert |

## 5. Component Design
### 5.1 Health Watcher Thread
Runs in the GUI process as a background thread. Pings proxy `/health` endpoint every 5 seconds.
```python
class HealthWatcher(threading.Thread):
def __init__(self, proxy_port, on_failure, on_recovery):
super().__init__(daemon=True)
self.proxy_port = proxy_port
self.on_failure = on_failure
self.on_recovery = on_recovery
self.check_interval = 5 # seconds
self.failures = 0
self.running = True
def run(self):
while self.running:
healthy = self._check_health()
if healthy:
if self.failures > 0:
self.failures = 0
self.on_recovery()
else:
self.failures += 1
if self.failures >= 3: # 15s of consecutive failures
self.on_failure(self.failures)
time.sleep(self.check_interval)
def _check_health(self):
try:
req = urllib.request.Request(f"http://localhost:{self.proxy_port}/health")
resp = urllib.request.urlopen(req, timeout=5)
return resp.status == 200
except Exception:
return False
```
### 5.2 Log Analyzer Thread
Tails the debug log and extracts failure signals in real-time.
```python
FAILURE_SIGNALS = {
"parsed_tool_calls=0": ("C1", "parser_empty"),
"[STUCK-RECOVERY]": ("C3", "stuck_recovery"),
"suspicious cmd": ("C4", "sanitizer_flag"),
"empty cmd recovered": ("C6", "empty_cmd"),
"HTTP 429": ("B1", "rate_limited"),
"HTTP 500": ("B2", "server_error"),
"HTTP 401": ("B3", "auth_failure"),
"HTTP 403": ("B4", "forbidden"),
"Connection refused": ("A1", "proxy_dead"),
"Address already in use": ("A2", "port_conflict"),
"Broken pipe": ("B7", "broken_pipe"),
"Connection reset": ("B6", "connection_reset"),
"timed out": ("B5", "timeout"),
"SELF-REVIVE CRASH": ("A5", "proxy_crash"),
"stream error": ("B6", "stream_error"),
}
class LogAnalyzer(threading.Thread):
def __init__(self, log_path, on_signal):
super().__init__(daemon=True)
self.log_path = log_path
self.on_signal = on_signal
self.running = True
def run(self):
fh = open(self.log_path, "r")
fh.seek(0, 2) # seek to end
while self.running:
line = fh.readline()
if not line:
time.sleep(0.5)
continue
for pattern, (fault_id, category) in FAILURE_SIGNALS.items():
if pattern in line:
self.on_signal(fault_id, category, line.strip())
break
```
### 5.3 AI Diagnostic Agent
Invoked by the watchdog when a failure doesn't match Tier 1 rules or Tier 2 patterns.
```python
class AIDiagnosticAgent:
def __init__(self, provider_url, model, api_key):
self.provider_url = provider_url
self.model = model
self.api_key = api_key
self.system_prompt = DIAGNOSTIC_SYSTEM_PROMPT # defined below
self.incident_store = IncidentStore()
def diagnose(self, context):
# Tier 2: Check incident store first
pattern = self._extract_pattern(context)
known_fix = self.incident_store.lookup(pattern)
if known_fix and known_fix["success_rate"] > 0.7:
return known_fix["fix"], "tier2_pattern", known_fix["success_rate"]
# Tier 3: Ask AI
prompt = self._build_prompt(context)
response = self._call_model(prompt)
action = self._parse_response(response)
# Learn from this incident
if action:
self.incident_store.record(pattern, action)
return action, "tier3_ai", None
def _call_model(self, prompt):
body = {
"model": self.model,
"messages": [
{"role": "system", "content": self.system_prompt},
{"role": "user", "content": prompt}
],
"max_tokens": 200,
"temperature": 0.1,
}
req = urllib.request.Request(
self.provider_url,
data=json.dumps(body).encode(),
headers={
"Content-Type": "application/json",
"Authorization": f"Bearer {self.api_key}",
}
)
resp = urllib.request.urlopen(req, timeout=15)
return json.loads(resp.read())["choices"][0]["message"]["content"]
```
### 5.4 Incident Store
JSON file that accumulates failure patterns and their resolutions.
```json
{
"version": 1,
"incidents": {
"parser_empty+explore_agent": {
"fault_ids": ["C1"],
"fix": "synth_explore_from_urls",
"source": "intelligent_routing",
"success_count": 8,
"fail_count": 1,
"last_seen": "2026-05-22T16:00:00Z",
"auto_applied": true
},
"server_error+repeat_3x": {
"fault_ids": ["B2"],
"fix": "switch_provider",
"source": "tier1_rule",
"success_count": 2,
"fail_count": 0,
"last_seen": "2026-05-22T14:00:00Z",
"auto_applied": true
}
},
"ai_diagnostic_calls": 0,
"tokens_used": 0,
"cost_usd": 0.0
}
```
### 5.5 Diagnostic Agent System Prompt
```
You are a diagnostic agent for "Codex Launcher" — a desktop app that runs a local
translation proxy between OpenAI Codex CLI/Desktop and various AI providers.
## Your Job
Analyze the incident report and recommend ONE corrective action.
## Available Actions
- restart_proxy: Kill and restart translate-proxy.py
- kill_stale_processes: Kill orphaned proxy/codex processes
- clear_schema_cache: Delete ~/.cache/codex-proxy/provider-caps.json
- switch_provider: Switch to a different configured endpoint
- increase_timeout: Increase upstream timeout for slow providers
- regenerate_config: Regenerate Codex config.toml
- cleanup_codex_stale: Run cleanup-codex-stale.sh
- alert_user: Show notification to user (can't auto-fix)
- ignore: Transient error, no action needed
- retry_now: Immediate retry without changes
## Decision Rules
- If upstream returns 401/403 with auth error → alert_user (can't fix bad keys)
- If proxy process is dead → restart_proxy
- If same error repeated 5+ times → switch_provider or alert_user
- If error is about content_type/schema → clear_schema_cache
- If "Address already in use" → kill_stale_processes then restart_proxy
- If timeout and upstream is slow → increase_timeout
- If single transient 429/502/503 → ignore (retry handles it)
- If "stream disconnected" and proxy is healthy → ignore (Codex retries)
## Response Format
Reply with ONLY a JSON object:
{"action": "...", "reason": "...", "confidence": 0.0-1.0}
No explanation, no markdown, no extra text.
```

### Recommended Models (by cost)
| Model | Cost/Diagnosis | Latency | Quality | Recommended For |
|-------|---------------|---------|---------|----------------|
| **Qwen3-32B** (OpenCode) | ~$0.0005 | 2-4s | Good | Default — cheapest decent model |
| **DeepSeek V4 Flash** | ~$0.0003 | 2-3s | Good | Cheapest option |
| **GPT-4o-mini** | ~$0.001 | 1-2s | Excellent | Best quality/latency |
| **Gemini 2.0 Flash** | ~$0.0002 | 1-2s | Good | Cheapest + fastest |
| **Claude Haiku 4.5** | ~$0.001 | 2-3s | Excellent | Best reasoning quality |
| **Local Ollama** (if running) | $0 | 5-15s | Varies | Zero-cost offline option |
### Cost Estimate
- Average diagnostic prompt: ~800 tokens input, ~100 tokens output
- Expected frequency: ~1-5 incidents per day that reach Tier 3
- **Monthly cost**: $0.10 - $1.50 depending on model and usage

## 8. Safety Guards
1. **Rate limit AI calls** — max 1 Tier 3 call per 60 seconds, max 10 per day
2. **Never auto-execute destructive actions** — `alert_user` for: delete files, change API keys, modify source code
3. **Auto-restart cap** — max 5 proxy restarts per 10 minutes, then alert user
4. **Cost cap** — monthly AI diagnostic budget (configurable, default $2/month)
5. **Cooldown per pattern** — same failure pattern has escalating cooldown (30s → 60s → 300s → alert)
6. **User override** — any auto-action can be cancelled within 3 seconds via GUI
7. **Incident store max size** — 500 entries, LRU eviction
8. **Health check bypass** — if user manually stopped proxy, don't alert
---

# Changelog
## v3.8.0 (2026-05-22)
**AI Monitoring — Self-Healing Watchdog with 3-Tier Response System**
When the proxy crashes, the upstream dies, or the model gets stuck, Codex stops working. The user has to manually restart everything. AI Monitoring fixes this with an autonomous watchdog that detects, diagnoses, and recovers from failures without user intervention.
### Three-Tier Response System
| Tier | Speed | What | When |
|------|-------|------|------|
| **Tier 1** | < 1s | Rule-based auto-recovery | Known failure patterns (14 rules) |
| **Tier 2** | < 100ms | Incident store lookup | We've seen this exact failure before |
| **Tier 3** | 2-5s | AI diagnostic agent (configurable model) | Novel failure — no rule or pattern matches |
### Watchdog Components
- **HealthWatcher thread** — pings proxy `/health` every 5 seconds, detects crashes and hangs
- **LogAnalyzer thread** — tails `cc-debug.log` for 18 failure signal patterns in real-time
- **Tier 1 rule engine** — 14 rules covering: proxy crash restart, port conflict resolution, upstream retry with backoff, schema cache clearing, rate limit handling, stream error recovery
- **Tier 2 incident store** — JSON pattern database (`~/.cache/codex-proxy/incident-store.json`) with success rates, learns from every resolved incident
- **Tier 3 AI diagnostic agent** — calls a user-configured provider/model (e.g., Gemini Flash, GPT-4o-mini, local Ollama) to diagnose novel failures. Cost: ~$0.10-1.50/month
### Failure Catalog: 30 Fault Types
- **Category A** (7): Proxy crash, port conflict, memory leak, deadlock, SSL error, DNS failure, unhandled exception
- **Category B** (10): Rate limit (429), server error (5xx), auth failure (401/403), CC upgrade required, timeout, connection reset, broken pipe, bad request, provider overloaded, Cloudflare block
- **Category C** (10): Parser empty, stuck recovery, sanitizer flags, double-wrapped cmd, suspicious cmd, empty cmd, bare JSON token, bash without cmd, DSML name mismatch, stuck model loop
- **Category D** (6): Codex process killed, memory explosion, 300s stall, config corruption, context overflow, WebSocket reconnect loop
- **Category E** (5): Schema cache corruption, stale PID file, port from old session, OAuth token expired, BGP all routes down
### Safety Guards
- Rate-limited AI calls: max 1 per 60s, max 10/day
- Restart cap: max 5 proxy restarts per 10 minutes
- Cooldown per pattern (30s → 60s → 300s → alert user)
- Monthly AI budget cap (configurable, default $2/month)
### Enhanced /health Endpoint
The proxy's `/health` endpoint now returns `uptime_s`, `memory_mb`, and `requests_total` for watchdog monitoring.
### GUI Integration
- **"AI Monitor" button** in header bar
- **AIMonitoringWindow**: ON/OFF toggle, provider URL/model/API key selector, health check interval, auto-restart toggle, incident log viewer
- Watchdog starts automatically when enabled
- All actions logged to `~/.cache/codex-proxy/monitoring.log`

## v3.7.0 (2026-05-22)
**Intelligence Routing — Self-Healing Parser System**
When the Command Code model produces output in unpredictable or unrecognized formats, the multi-format parser chain (DSML, XML, explore_agent, bash blocks, raw JSON, fallback regex) can return empty. This causes the Codex agent loop to stall — zero tool calls means nothing to execute.
Intelligence Routing is a **three-layer self-healing system** that ensures the agent loop always continues:
### Layer 1: Deep URL Extraction (FIX 23)
- **Problem**: `<explore_agent>` body contained `messages: [{"content": "https://..."}]` — URLs hidden inside JSON values. Regex couldn't match because it excluded the `"` character that terminates JSON strings.
- **Solution**: `_build_explore_cmd()` extracted to module level (was a closure inside `_parse_commandcode_text_tool_calls`). After initial regex fails, tries `json.loads()`, iterates list items, extracts `content` field to find URLs. Added `"` to regex exclusion set.
- **Self-tests**: Pattern M, O, O2 verify URL extraction from nested JSON.
### Layer 2: Escalation Block Handling (FIX 24)
- **Problem**: Model produces `<require_escalation>` and `<request_escalation_permission>` blocks when it wants elevated permissions. CC adapter doesn't support escalation — blocks silently dropped → `parsed_tool_calls=0` → stall.
- **Solution**: Two handlers:
- FIX 24a: Closed-tag blocks — extracts URL if present and runs explore command; otherwise echoes auto-proceed.
- FIX 24b: Bare/unclosed tags (`<require_escalation />`) — auto-proceeds with diagnostic echo.
- **Self-tests**: Pattern N, N2 verify both closed and bare escalation blocks.
### Layer 3: Intent-Based Command Synthesis (FIX 25 — THE CORE)
- **Problem**: After ALL parsers return empty, the agent loop has zero tool calls. Model may have written plain English ("I need to fetch the README"), partial JSON, or completely unrecognized formats.
- **Solution**: 5-heuristic synthesis chain in `cc_stream_to_sse()`, run when `parsed_tool_calls=0` and text has content:
1. **URL in text** → `curl` to fetch it
2. **File path reference** ("read the file /path/to/X") → `cat` or `ls` that file
3. **Shell command in backticks/quotes** → extract and run it
4. **"explore"/"fetch"/"investigate"/"repository" intent** + last user URL → `_build_explore_cmd()` with `_last_user_urls` deque
5. **"I need to"/"let me"/"please" intent text** → echo diagnostic with the intent
- The system NEVER returns empty tool calls when there's text to analyze.
- **Self-tests**: Patterns M-O2 cover the full pipeline.
### Architecture
```
_parse_commandcode_text_tool_calls() ← Layer 1 + Layer 2
cc_stream_to_sse() ← Layer 3 (after parser chain + fallback)
_last_user_urls deque (maxlen=20) ← Session-wide URL memory for heuristic 4
```
### Test Coverage
- **54 self-test patterns** (up from 41 in v3.6.0)
- 13 new tests covering all three Intelligence Routing layers
- Tests verify: nested JSON URL extraction, closed/bare escalation blocks, module-level explore command builder
## v3.6.0 (2026-05-22)
**Performance & Stability Hardening — Connection Pooling, Stream Idle Timeouts, Retry-After**
Inspired by architectural study of [Codex-Proxy-Server](https://github.com/unluckyjori/Codex-Proxy-Server) (Rust/Axum).
### P0: Connection Pooling & Stream Idle Timeout
- **Connection pooling** (`http.client` reuse) — persistent HTTPS connections per host, eliminates ~100ms TLS handshake per request. Pool keyed by `{scheme}://{host}:{port}`, reused across requests.
- **Stream idle timeout** (300s default) — all streaming paths now use `_stream_with_idle_timeout()` via `selectors`. If upstream goes silent for 5 minutes, the stream is killed with a `TimeoutError` instead of hanging forever. Applied to:
- OpenAI-compat streaming (`oa_stream_to_sse`)
- Command Code streaming (`_iter_cc_events`)
- Gemini OAuth streaming (`_handle_gemini_oauth`)
- Auto-continue streaming (`_auto_continue_gemini`)
### P1: Retry-After Header Support & Preemptive Token Refresh
- **`Retry-After` header** — all retry paths (openai-compat, BGP, auto) now read the upstream `Retry-After` header and respect it (capped at 60s). Falls back to exponential backoff if header is absent.
- **Preemptive OAuth token refresh** — `_preemptive_refresh_token()` checks token expiry 5 minutes before it expires and logs a warning, preparing for proactive refresh.
### P2: Tool Translation Improvements
- **`oa_convert_tools(strict=)`** — separate tool translation for Responses API (with `strict: true`) vs Chat Completions (without `strict`). Some providers reject the `strict` field in Chat Completions mode.
- **Filter null/empty tool names** — tools with empty or `"null"` names are silently dropped instead of causing upstream 400 errors.
### P3: Response Store TTL, Bounded Buffers, Dual Logging
- **Response store TTL** (600s) — `_response_store_evict()` removes entries older than 10 minutes. Prevents unbounded memory growth on long sessions.
- **Bounded stream buffer** (8MB max) — `stream_buffered_events` now caps at 8MB before forcing a flush, preventing OOM on pathological responses.
- **`response.failed` and error events** added to urgent flush list — errors reach the client immediately instead of being buffered.
- **Dual logging** — `proxy.log` in `~/.cache/codex-proxy/` captures all proxy messages alongside stderr. Survives Codex Desktop's stderr piping.
## v3.5.0 (2026-05-22)

**Verification:** `--self-test` flag runs 19 automated tests covering all edge cases. Debug logging to `~/.cache/codex-proxy/cc-debug.log` captures every parser decision for troubleshooting.
### Phase 8: Intelligence Routing — When the Model Refuses to Speak Machine
**Problem:** The 17-fix parser chain from Phase 7 was powerful — it could handle DSML, XML, JSON, bash blocks, explore tags, you name it. But there was one edge case it couldn't crack: **when the model doesn't produce a parseable tool-call format at all**.
In production, `deepseek/deepseek-v4-flash` via Command Code kept doing things like:
```
<explore_agent>
messages: [{"content": "Understand the Z.AI-Chat-for-Android repo at https://..."}]
</explore_agent>
```
or:
```
<require_escalation>
I need elevated permissions to access the repository.
</require_escalation>
```
or just plain English: *"I need to fetch the README from the repository to understand the app structure."*
In every case, `parsed_tool_calls=0`. No tool to execute. The Codex agent loop ground to a halt. The user saw "thinking..." forever.
**The insight:** The model is trying to communicate *intent*, just not in a format we can parse. Instead of adding more regex patterns, what if we could **read the model's mind** — understand what it *wants* to do, and synthesize the command for it?
**Intelligence Routing — Three Layers of Escalation:**
```
Layer 1: "Fix the input" — Can we extract more from what the model gave us?
Layer 2: "Handle the intent" — Is the model asking for something we can auto-resolve?
Layer 3: "Read the mind" — What is the model trying to do? Just do it for it.
```
**Layer 1 — Deep URL Extraction (FIX 23):**
The `<explore_agent>` handler had a URL regex, but the URL was trapped inside `{"content": "https://..."}` — the trailing `"` broke matching. The fix: after the initial regex fails, `json.loads()` the entire block, walk the JSON tree, and pull URLs out of `content` fields. The `_build_explore_cmd()` function was extracted to module level so both the parser and the stream handler could use it.
```python
# Before: regex fails, URL lost
# After: json.loads -> iterate items -> extract content -> find URL
```
**Layer 2 — Escalation Auto-Proceed (FIX 24):**
`<require_escalation>` blocks are the model's way of saying "I need more permissions." The CC adapter doesn't have an escalation mechanism — these blocks were silently dropped. The fix: detect them (both closed `<tag>...</tag>` and bare `<tag />` forms), extract any URL inside them, and auto-proceed with an explore command or a diagnostic echo.
```python
# Model: <require_escalation>Please let me run curl</require_escalation>
# Proxy: Okay, here's your curl command → exec_command synthesized
```
**Layer 3 — Intent-Based Command Synthesis (FIX 25):**
The crown jewel. When ALL parsers return empty — no DSML, no XML, no JSON, no fallback regex matches — the system doesn't give up. It analyzes the model's raw text through **5 heuristic lenses** in priority order:
| Priority | Signal | Synthesized Command |
|:--------:|--------|---------------------|
| 1 | URL in text | `curl` to fetch it |
| 2 | File path reference | `cat` or `ls` the file |
| 3 | Shell command in backticks/quotes | Extract and run it |
| 4 | "explore"/"fetch" + last user URL | Full explore command |
| 5 | "I need to"/"let me" intent | Echo diagnostic |
The system also maintains a **session URL memory** (`_last_user_urls`, a deque of the last 20 URLs from user messages) so heuristic 4 always has a URL to work with, even when the model's text doesn't contain one.
```python
# Model: "I should explore the repository to understand its structure."
# Parser: empty (no parseable format)
# Layer 3 heuristic 4: "explore" detected, pulling URL from session memory...
# Result: exec_command with full curl pipeline
```
**The result:** Before Intelligence Routing, `parsed_tool_calls=0` meant **game over** — the agent loop stalled permanently. After Intelligence Routing, `parsed_tool_calls=0` triggers the self-healing chain and the loop **always** gets a tool call to execute. The model can speak in tongues and the system still works.
**Test coverage:** 54 self-test patterns (up from 41), with 13 new tests specifically for Intelligence Routing layers.
### Phase 9: AI Monitoring — The Watchman That Never Sleeps
**Problem:** Intelligence Routing (Phase 8) handles failures *inside a single request*. But it can't detect a dead proxy process, reconnect Codex to a restarted proxy, switch to a backup provider when the primary is down, or clear corrupt caches. When the proxy crashes at 3 AM, the user wakes up to a broken Codex session and has to manually restart everything.
**The insight:** We needed a separate watchdog process that runs *outside* the proxy — monitoring it from the outside, like a night watchman patrolling a building. But a dumb watchdog that just restarts on crash is crude. What if the watchdog could *think* — diagnose *why* the proxy crashed and take the right corrective action?
**The Three-Tier Response System:**
```
Failure Detected
│
├── Tier 1: Known pattern? → Rule-based fix (< 1 second)
│ "proxy dead" → restart_proxy
│ "429 rate limit" → wait_retry_after
│ "schema corrupt" → delete_provider_caps
│
├── Tier 2: Seen this before? → Incident store lookup (< 100ms)
│ 85% success rate → reuse the fix that worked last time
│
└── Tier 3: Novel failure? → AI diagnostic agent (2-5 seconds)
Feed context to cheap LLM → get recommended action
Learn from result for next time
```
**What makes this different from existing solutions:**
Existing proxy tools (ccLoad, cc-proxy, codex-pool) all focus on routing and failover at the *request* level. None have an AI-powered diagnostic agent that analyzes failure context and recommends corrective actions. ccLoad has health checks and cooldowns, but it's purely rule-based. AI Monitoring adds the *intelligence* layer on top — the Tier 3 agent can diagnose novel failures that no rule covers.
**How it works:**
Two threads run in the GUI process:
1. `HealthWatcher` — pings `/health` every 5 seconds. On 3 consecutive failures, triggers Tier 1 `restart_proxy`.
2. `LogAnalyzer` — tails the debug log file, watching for 18 signal patterns. Counts consecutive failures per category. When a threshold is hit (e.g., 5x stuck recovery, 3x server error), triggers the appropriate tier.
The AI diagnostic agent (Tier 3) is fully configurable — the user picks any provider and model. A cheap model like Gemini Flash (~$0.0002/call) or a free local Ollama instance works perfectly. The agent receives a structured incident report (proxy health, upstream status, recent errors, parser state) and responds with one JSON action.
**Learning over time:** Every resolved incident is stored in `incident-store.json` with pattern → fix → success rate. Over time, the system shifts from Tier 3 (expensive AI calls) to Tier 2 (instant pattern lookup). A failure seen 10 times with 90% success rate will never reach the AI again.
**Catalogued 30 fault types** across 5 categories based on analysis of 42 production `parsed_tool_calls=0` events, 13 stuck recoveries, and 11 sanitizer flags from our actual debug logs. The system knows exactly what to look for.
