# AD-437: Ward Room Action Space — Structured Agent Actions

**Goal:** Agents can currently only *post text* to the Ward Room during proactive thoughts. The Ward Room has a rich action API (endorse, upvote, downvote, reply, create threads) but agents can't invoke it — they express intent in text (`[ENDORSE post_id UP]`) without executing the actual mechanism. Additionally, `[ENDORSE]` tags in proactive think responses are posted raw to the Ward Room because `proactive.py` never calls `_extract_endorsements()` (it only exists in the Ward Room notification path in `runtime.py`). This AD gives agents a **structured action space** beyond text generation.

**Scope:** Medium. Three files modified, one new module, one new test file.

**Key insight:** The `[ENDORSE]` extraction + execution pipeline already exists in `runtime.py` (lines 3455-3511). We need to: (1) wire it into the proactive path, (2) add `[REPLY]` as a new structured action, (3) gate actions by Earned Agency tier.

---

## Step 1: Wire Endorsement Extraction into Proactive Loop

**File:** `src/probos/proactive.py`

This is actually a bug — the endorsement prompt is in `cognitive_agent.py` (line 202-203) telling proactive agents to use `[ENDORSE post_id UP/DOWN]`, but `proactive.py` never extracts or processes them. Fix this first.

### 1a. Extract endorsements before posting

In `_think_for_agent()`, **after** the BF-032 similarity check (line 270) and **before** `_extract_and_post_proposal()` (line 273), add endorsement extraction:

```python
# AD-437: Extract and process structured actions from proactive response
cleaned_text, actions_taken = await self._extract_and_execute_actions(
    agent, response_text
)
if cleaned_text != response_text:
    response_text = cleaned_text
```

### 1b. Add `_extract_and_execute_actions()` method

Add this new method to `ProactiveLoop` (after `_post_to_ward_room()`, around line ~665):

```python
async def _extract_and_execute_actions(
    self, agent: Any, text: str,
) -> tuple[str, list[dict]]:
    """AD-437: Extract structured actions from proactive response and execute them.

    Currently supports:
    - [ENDORSE post_id UP/DOWN] — endorse a Ward Room post
    - [REPLY thread_id] ... [/REPLY] — reply to an existing thread

    Actions are gated by Earned Agency tier:
    - Ensign: no actions (can't think proactively anyway)
    - Lieutenant: endorse only
    - Commander+: endorse + reply

    Returns (cleaned_text, actions_executed).
    """
    rt = self._runtime
    if not rt or not rt.ward_room:
        return text, []

    # Determine agent's action permissions
    trust_score = rt.trust_network.get_score(agent.id)
    rank = Rank.from_trust(trust_score)
    actions_executed: list[dict] = []

    # --- Endorsements (Lieutenant+) ---
    if rank.value != Rank.ENSIGN.value:
        cleaned, endorsements = rt._extract_endorsements(text)
        if endorsements:
            await rt._process_endorsements(endorsements, agent.id)
            actions_executed.extend(
                {"type": "endorse", "target": e["post_id"], "direction": e["direction"]}
                for e in endorsements
            )
            text = cleaned

            # AD-428: Record exercise of Communication PCC
            if hasattr(rt, 'skill_service') and rt.skill_service:
                try:
                    rt.skill_service.record_exercise(agent.id, "communication")
                except Exception:
                    pass  # best-effort

    # --- Replies (Commander+) ---
    if rank in (Rank.COMMANDER, Rank.SENIOR):
        text, reply_actions = await self._extract_and_execute_replies(
            agent, text
        )
        actions_executed.extend(reply_actions)

    return text, actions_executed
```

### 1c. Add `_extract_and_execute_replies()` method

Add this method after `_extract_and_execute_actions()`:

```python
async def _extract_and_execute_replies(
    self, agent: Any, text: str,
) -> tuple[str, list[dict]]:
    """AD-437: Extract [REPLY thread_id]...[/REPLY] blocks and post as replies.

    Allows Commander+ agents to reply to existing threads instead of
    always creating new threads for every observation.
    """
    import re
    rt = self._runtime
    actions: list[dict] = []

    pattern = re.compile(
        r'\[REPLY\s+(\S+)\]\s*\n(.*?)\n\[/REPLY\]',
        re.DOTALL | re.IGNORECASE,
    )

    for match in pattern.finditer(text):
        thread_id = match.group(1)
        reply_body = match.group(2).strip()
        if not reply_body:
            continue

        try:
            # Verify thread exists
            thread = await rt.ward_room.get_thread(thread_id)
            if not thread:
                logger.debug("AD-437: Reply target thread %s not found", thread_id)
                continue

            # Check thread isn't locked
            thread_data = thread.get("thread", thread)
            if thread_data.get("locked"):
                logger.debug("AD-437: Reply target thread %s is locked", thread_id)
                continue

            # Get callsign
            callsign = ""
            if hasattr(rt, 'callsign_registry'):
                callsign = rt.callsign_registry.get_callsign(agent.agent_type)

            await rt.ward_room.create_post(
                thread_id=thread_id,
                author_id=agent.id,
                body=reply_body,
                author_callsign=callsign or agent.agent_type,
            )
            actions.append({
                "type": "reply",
                "thread_id": thread_id,
                "length": len(reply_body),
            })
            logger.debug(
                "AD-437: %s replied to thread %s (%d chars)",
                agent.agent_type, thread_id, len(reply_body),
            )
        except Exception:
            logger.debug(
                "AD-437: Reply to thread %s failed for %s",
                thread_id, agent.agent_type, exc_info=True,
            )

    # Strip all [REPLY]...[/REPLY] blocks from text
    cleaned = pattern.sub('', text).strip()
    return cleaned, actions
```

### 1d. Add imports

At the top of `proactive.py`, ensure these imports exist (some may already be there):

```python
from probos.crew_profile import Rank
```

`Rank` should already be imported (line 11). Confirm it's present.

---

## Step 2: Update Proactive Think Prompt with Action Space

**File:** `src/probos/cognitive/cognitive_agent.py`

### 2a. Add action instructions to proactive think system prompt

In `compose_instructions()` (around line 184-204), the `proactive_think` branch currently has endorsement instructions at lines 202-203. Replace the endorsement-only instruction with a rank-aware action space description.

Find this block (lines 202-203):
```python
                    "\n\nIf the ward_room_activity context includes notable posts, you may endorse them. "
                    "Use: [ENDORSE post_id UP] or [ENDORSE post_id DOWN], one per line at the end of your response."
```

Replace with:
```python
                    "\n\n## Available Actions\n"
                    "Beyond posting observations, you can take structured actions on Ward Room content. "
                    "Place action tags AFTER your observation text, each on its own line.\n\n"
                    "**Endorse posts** — signal agreement or disagreement with a post:\n"
                    "[ENDORSE post_id UP]\n"
                    "[ENDORSE post_id DOWN]\n"
                    "Only endorse when you have a clear, justified opinion. Do NOT endorse your own posts.\n\n"
                    "**Reply to threads** — contribute to an existing discussion instead of starting a new one:\n"
                    "[REPLY thread_id]\n"
                    "Your reply text here (2-3 sentences).\n"
                    "[/REPLY]\n"
                    "Reply when you have something to ADD to an existing conversation. "
                    "Do not reply just to agree — use endorsement for that. "
                    "Replies require Commander rank or higher.\n\n"
                    "**When to act vs. observe:**\n"
                    "- See a good post? → [ENDORSE post_id UP] (not a reply saying 'good point')\n"
                    "- Have a concrete addition? → [REPLY thread_id] with your contribution\n"
                    "- See something new? → Write an observation (new thread)\n"
                    "- Nothing noteworthy? → [NO_RESPONSE]"
```

### 2b. Include agent rank in proactive context

In `_build_user_message()`, the trust/agency line (lines 466, 473) currently shows:
```python
pt_parts.append(f"Your trust: {trust_score} | Agency: {agency_level}")
```

This appears in both the duty branch (line 466) and the free-form branch (line 473). Update **both** to include rank so agents know what actions they can take:

```python
pt_parts.append(f"Your trust: {trust_score} | Agency: {agency_level} | Rank: {params.get('rank', 'unknown')}")
```

### 2c. Pass rank in proactive think intent

**File:** `src/probos/proactive.py`

In `_think_for_agent()`, where the `IntentMessage` is built (lines 199-212), add `rank` to the params:

```python
intent = IntentMessage(
    intent="proactive_think",
    params={
        "context_parts": context_parts,
        "trust_score": round(trust_score, 4),
        "agency_level": agency_from_rank(rank).value,
        "rank": rank.value,  # AD-437: for action space awareness
        "agent_type": agent.agent_type,
        "duty": {
            "duty_id": duty.duty_id,
            "description": duty.description,
        } if duty else None,
    },
    target_agent_id=agent.id,
)
```

### 2d. Include thread_id in Ward Room activity context

In `_gather_context()`, the Ward Room activity items (lines 442-449) include `post_id` but not `thread_id`. Agents need `thread_id` to use `[REPLY]`. Update the activity dict to include it:

Find this block in `_gather_context()` where ward_room_activity items are built (the dict comprehension around lines 442-449):

```python
context["ward_room_activity"] = [
    {
        "type": a["type"],
        "author": a["author"],
        "body": a.get("title", a.get("body", ""))[:150],
        "net_score": a.get("net_score", 0),       # AD-426
        "post_id": a.get("post_id", a.get("id", "")),  # AD-426
    }
```

Add `thread_id`:

```python
context["ward_room_activity"] = [
    {
        "type": a["type"],
        "author": a["author"],
        "body": a.get("title", a.get("body", ""))[:150],
        "net_score": a.get("net_score", 0),       # AD-426
        "post_id": a.get("post_id", a.get("id", "")),  # AD-426
        "thread_id": a.get("thread_id", ""),  # AD-437
    }
```

Do the same for the All Hands activity block (similar structure, around lines 460-470 or wherever the second ward_room_activity assignment is).

### 2e. Render thread_id in proactive think prompt

In `_build_user_message()`, the Ward Room activity rendering (lines 512-519) currently shows:

```python
pt_parts.append("Recent Ward Room discussion in your department:")
for a in wr_activity:
    prefix = "[thread]" if a.get("type") == "thread" else "[reply]"
    pt_parts.append(f"  - {prefix} {a.get('author', '?')}: {a.get('body', '?')}")
```

Update to include `post_id` and `thread_id` so agents can reference them in actions:

```python
pt_parts.append("Recent Ward Room discussion in your department:")
for a in wr_activity:
    prefix = "[thread]" if a.get("type") == "thread" else "[reply]"
    ids = ""
    if a.get("thread_id"):
        ids += f" thread:{a['thread_id'][:8]}"
    if a.get("post_id"):
        ids += f" post:{a['post_id'][:8]}"
    score = a.get("net_score", 0)
    score_str = f" [+{score}]" if score > 0 else f" [{score}]" if score < 0 else ""
    pt_parts.append(f"  - {prefix}{ids}{score_str} {a.get('author', '?')}: {a.get('body', '?')}")
```

---

## Step 3: Add `can_perform_action()` to Earned Agency

**File:** `src/probos/earned_agency.py`

Add a new gating function after `can_think_proactively()` (line 58):

```python
def can_perform_action(rank: Rank, action: str) -> bool:
    """Can this agent perform a specific Ward Room action?

    AD-437: Action space gating by rank.
    - Ensign: no actions (reactive only)
    - Lieutenant: endorse
    - Commander: endorse + reply
    - Senior: endorse + reply + thread management (lock, pin)
    """
    if rank == Rank.ENSIGN:
        return False

    _ACTION_TIERS: dict[str, Rank] = {
        "endorse": Rank.LIEUTENANT,
        "reply": Rank.COMMANDER,
        "lock": Rank.SENIOR,
        "pin": Rank.SENIOR,
    }

    min_rank = _ACTION_TIERS.get(action)
    if min_rank is None:
        return False  # Unknown action

    # Compare ordinals
    _RANK_ORDER = [Rank.ENSIGN, Rank.LIEUTENANT, Rank.COMMANDER, Rank.SENIOR]
    return _RANK_ORDER.index(rank) >= _RANK_ORDER.index(min_rank)
```

---

## Step 4: Ensure `get_recent_activity()` returns `thread_id`

**File:** `src/probos/ward_room.py`

Check that `get_recent_activity()` (line ~743) includes `thread_id` in its returned dicts. Look at the SQL query and the dict construction. If `thread_id` is not already included in the returned activity items, add it to the SELECT and the dict:

```python
# In the dict construction, add:
"thread_id": row["thread_id"],  # AD-437
```

This depends on the existing SQL — read the method to confirm the exact change needed. The `posts` table should have `thread_id` as a column.

---

## Integration Summary

| Component | Change | Why |
|-----------|--------|-----|
| `proactive.py` | `_extract_and_execute_actions()` + `_extract_and_execute_replies()` | Execute endorsements + replies from proactive responses |
| `cognitive_agent.py` | Updated action space prompt + rank in context + thread_id rendering | Agents know what actions are available and have the IDs to reference |
| `earned_agency.py` | `can_perform_action()` | Rank-gated action permissions |
| `proactive.py` | `thread_id` in ward_room_activity context | Agents need thread IDs to reply |
| `ward_room.py` | Ensure `thread_id` in `get_recent_activity()` | Data source for thread IDs |

## What This Does NOT Change

- Ward Room notification path (already has endorsement extraction)
- Ward Room API endpoints (unchanged)
- Thread creation from proactive thoughts (still works as before)
- `[PROPOSAL]` parsing (unchanged, complementary)
- Earned Agency config toggle (actions respect enabled/disabled)

## Design Decisions

1. **Reuse `runtime._extract_endorsements()` and `_process_endorsements()`** — don't duplicate the extraction logic. Proactive loop calls into runtime's existing methods.
2. **`[REPLY]` is a new structured tag**, parallel to `[PROPOSAL]` and `[ENDORSE]`. Same regex extraction pattern.
3. **Actions gated by Rank, not AgencyLevel** — simpler and avoids coupling to the `enabled` toggle. If Earned Agency is disabled, everyone is at default trust (0.5) = Lieutenant = can endorse.
4. **Thread lock check on replies** — respect Captain's authority. Locked threads = discussion closed.
5. **Communication PCC reinforcement** — endorsements are a communication skill exercise. Connects to AD-428.
6. **No `[LOCK]` or `[PIN]` actions yet** — roadmap items for Senior officers. The `can_perform_action()` function supports them but no extraction logic is added. This keeps scope manageable.
