# Phase 2: Agent Features Verification Report

**Phase Goal:** The AI employee maintains conversation memory, can execute tools, handles WhatsApp messages, and escalates to humans when rules trigger — making it a capable product rather than a demo
**Verified:** 2026-03-24T01:18:24Z
**Status:** human_needed
**Re-verification:** Yes — after gap closure (Plan 02-06)

## Goal Achievement

### Observable Truths (from ROADMAP.md Success Criteria)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Agent remembers context from earlier in the same conversation (30+ turns without degradation) | VERIFIED | Redis sliding window (RPUSH/LTRIM, 20-msg default) in `short_term.py`; pgvector HNSW retrieval in `long_term.py`; both wired in `_process_message` via `get_recent_messages` + `retrieve_relevant` + `build_messages_with_memory`. No regression. |
| 2 | A user can send a WhatsApp message to the AI employee and receive a reply (per-tenant phone isolation + Meta 2026 scoping) | VERIFIED | Inbound pipeline complete. Outbound routing now wired: `_send_response` called at lines 355, 395, 438, 556 in `_process_message`; `_update_slack_placeholder` only called inside `_send_response` (line 722). `handle_message` pops `phone_number_id` and `bot_token` before `model_validate` (lines 223-224); `wa_id` extracted from `msg.sender.user_id` and injected into extras dict (lines 234-244). |
| 3 | Agent can invoke a registered tool and incorporate the result into its response | VERIFIED | Tool registry with 4 built-ins, `execute_tool` with JSON Schema validation, multi-turn loop (max 5 iterations) all wired in `runner.py`; `_process_message` builds `tool_registry` and passes to `run_agent`. No regression. |
| 4 | When escalation rule triggers, conversation and full context are handed off to human with no information lost | VERIFIED | `check_escalation_rules` and `escalate_to_human` imported at module level (line 71); pre-check at lines 386-396 (Redis `escalation_status_key` check before LLM call); post-check at lines 502-528 (`check_escalation_rules` called after `run_agent`, `escalate_to_human` called when rule matches and `escalation_assignee` is set). `_build_conversation_metadata` helper provides billing-keyword metadata. |
| 5 | Every LLM call, tool invocation, and handoff event is recorded in an immutable audit trail queryable by tenant | VERIFIED | `AuditLogger` initialized at line 375; `log_llm_call` per LLM iteration in `runner.py`; `log_tool_call` in `execute_tool`; `log_escalation` called inside `escalate_to_human`. `audit_events` table has `REVOKE UPDATE, DELETE`. No regression. |

**Score: 5/5 truths verified**

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `packages/orchestrator/orchestrator/tasks.py` | 677 | `_execute_pending_tool` returns stub: "Full tool execution will be implemented in Phase 3 with per-tenant OAuth." | Warning | Confirmed tool execution after user approval is deferred to Phase 3 — this is an acknowledged deviation, not a regression |

No new anti-patterns introduced by Plan 02-06.

### Human Verification Required

#### 1. WhatsApp End-to-End Delivery

**Test:** Configure a WhatsApp-connected tenant, send a WhatsApp message, wait for LLM response.
**Expected:** The AI employee's reply appears in the WhatsApp conversation thread.
**Why human:** Requires real Meta Cloud API credentials, a registered phone_number_id, and live webhook traffic. Static analysis confirms the outbound path is now wired (`_send_response` calls `send_whatsapp_message` with correct parameters), but delivery cannot be verified without live infrastructure.

#### 2. Escalation DM Delivery

**Test:** Configure an agent with `escalation_assignee` (Slack user ID) and a billing escalation rule. Send multiple messages containing billing keywords (e.g., "billing", "invoice", "refund") to trigger the rule.
**Expected:** The configured Slack user receives a DM with the full conversation transcript. Subsequent messages receive the assistant-mode reply without LLM processing.
**Why human:** Requires a live Slack workspace, valid bot token, valid `escalation_assignee` user ID, and triggering the keyword threshold. The pre-check and post-check wiring is verified in code and unit tests, but end-to-end delivery requires the Slack API.

#### 3. WhatsApp Business-Function Scoping (Tier 2) — Behavioural Compliance

**Test:** Configure an agent with `tool_assignments = ["customer support", "billing inquiries"]`. Send a borderline off-topic message via WhatsApp (e.g., "Can you help me write a poem?").
**Expected:** The LLM system prompt contains "You only handle: customer support, billing inquiries" and the response redirects the user to allowed topics.
**Why human:** The system prompt injection is statically verified (`build_system_prompt` appends the clause at line 187 when `channel == "whatsapp"` and `tool_assignments` is non-empty). LLM behavioural compliance with that constraint requires a live inference call.

---

### Gaps Summary

All three gaps from the initial verification are confirmed closed in the actual codebase:

1. **Escalation wiring (AGNT-05):** `check_escalation_rules` and `escalate_to_human` are imported at module level (line 71) and called from `_process_message`. Pre-check gates already-escalated conversations at lines 386-396. Post-check evaluates rules after `run_agent` at lines 504-528. `_build_conversation_metadata` provides billing-keyword metadata.

2. **WhatsApp outbound routing (CHAN-03):** `_send_response` is called at all four response delivery points (lines 355, 395, 438, 556). No direct `_update_slack_placeholder` calls remain in `_process_message` — the only call is inside `_send_response` itself (line 722). `handle_message` pops `phone_number_id` and `bot_token` before `model_validate` and injects `wa_id` into the extras dict.

3. **Tier-2 WhatsApp system prompt scoping (CHAN-04):** `build_system_prompt` accepts a `channel` parameter and appends the business-function constraint at line 182-190. `build_messages_with_memory` and `build_messages_with_media` pass `channel` through. `_process_message` passes `str(msg.channel)` at line 482.

No regressions detected in previously-verified truths (memory pipeline, tool execution, audit logging).

Remaining open items are behavioural and require human verification with live infrastructure.
