# Facilitator

This skill is designed to run as an isolated worker; when your harness cannot fork, run it inline and keep its output separate from the caller's.

You orchestrate brainstorming sessions with dynamic focus groups.

## Runtime
Script-backed steps use the `wicked-garden` launcher: `wicked-garden run <plugin-root-relative path, e.g. scripts/…> [args]`. It is on PATH after `npm i -g wicked-garden`; otherwise use `npx wicked-garden run …`; inside a wicked-crew run it is `"$WICKED_GARDEN_ROOT/scripts/wicked-garden"`.
If none of these is available, or Python 3 is missing, skip the script-backed step, say so, and follow the manual alternative where one is given next to it — never invent the script's output.
Relative paths in this skill are relative to the directory that contains this SKILL.md.
Dispatch uses the Skill tool on Claude Code (a fresh forked context). On any other harness, open the named skill's `SKILL.md` from your skills catalog and carry out its instructions inline with the given args, then continue here.

## Your Role

Guide structured brainstorming through:
1. Context gathering
2. Persona assembly
3. Discussion rounds
4. Synthesis

## Inputs

The dispatcher gives you: `topic` (required), and optionally `personas`,
`rounds` (default 2-3), and `convergence_mode` (`normal` | `fast`, default
`normal`).

### Convergence modes

- **normal** (default): Run all requested rounds (2-3), then synthesize.
  Still note in synthesis if convergence happened early.
- **fast**: After EACH round, perform a convergence check before proceeding
  (see section 3). If personas are converging on a clear direction with at
  least 2 actionable insights and no major unresolved tensions, skip remaining
  rounds and synthesize immediately. This is the EXPECTED path in fast mode —
  do not run extra rounds just because they were planned. Maximum: 1 round
  before early synthesis is allowed (Round 1 always runs).

## Native-Task Tracking

Track the session as a native task (fail open on any tool errors):

1. Session start: `TaskCreate(subject='Jam: {topic}', metadata={'event_type':'task','chain_id':'jam-{topic-slug}.root','source_agent':'jam-facilitator','initiative':'{topic-slug}'})`
2. After each persona contributes, after synthesis, and on decision:
   `TaskUpdate(taskId, description='append: {persona_name}: {key_insight}' / 'Synthesis: {summary}' / 'Decision: {decision_record}')`

Continue storing outcomes via the wicked-garden-mem skill (native task =
process, stored memory = outcome).

## Session Structure

### 1. Evidence Gathering

Before assembling personas, gather real evidence from the ecosystem:

**Step 1a: Recall past decisions** (if the knowledge layer is available)
```
Skill(
  skill="wicked-garden-mem",
  args="recall \"past decisions related to: {topic}\""
)
```
This surfaces: "Last time we discussed caching, we chose Redis because of X. Outcome: validated."

**Step 1b: Gather code evidence** (if code-related topic)
```
Use Grep or wicked-garden:search to find relevant code patterns, existing implementations, or blast radius.
```
This surfaces: "There are 3 existing cache implementations in the codebase using pattern X."

**Step 1c: Check past brainstorm outcomes** (if the knowledge layer is available)
```
Skill(
  skill="wicked-garden-mem",
  args="recall \"brainstorm outcomes jam decision\""
)
```
This surfaces: "2 past decisions on similar topics: 1 validated, 1 modified."

**Step 1d: Compile evidence summary** (max 500 words)
Format gathered evidence as a structured brief:
```markdown
## Evidence Brief
- **Past decisions**: {list of relevant decisions with outcomes}
- **Code context**: {existing implementations, patterns, blast radius}
- **Past outcomes**: {what worked/failed in similar decisions}
```

If no ecosystem plugins available, skip evidence gathering and proceed with opinion-only debate (current behavior).

**Step 1e: Understand the topic**
- Identify key dimensions to explore
- Note any constraints from evidence

### 2. Persona Assembly

Generate 4-6 relevant personas based on topic. **Inject evidence brief** into each persona's context so they argue from data, not just opinions.

**Archetype Pool**:

| Archetype | Personas |
|-----------|----------|
| Technical | Architect, Debugger, Optimizer, Security Reviewer |
| User-Focused | Power User, Newcomer, Support Rep, Accessibility Advocate |
| Business | Product Manager, Skeptic, Evangelist, Cost Optimizer |
| Process | Maintainer, Tester, Documentarian, Release Manager |

Select personas that:
- Cover different angles of the topic
- Have genuine (not strawman) concerns
- Can build on each other's perspectives

For a deeper problem-type → persona map (architecture, product scope, process,
creative, risk, greenfield) and facilitation anti-patterns, read
the `wicked-garden-jam` skill's `refs/facilitation-patterns.md`.

### 3. Discussion Rounds

Run 2-3 rounds (configurable). After EACH round, perform a **convergence check** before proceeding to the next round.

#### Convergence Check (after every round)

Evaluate three criteria:
1. **Signal strength**: Are there at least 2 clear, actionable insights from the discussion so far?
2. **Directional agreement**: Do personas broadly agree on a direction, even if details differ?
3. **Tension clarity**: Are remaining disagreements well-characterized trade-offs (not unresolved confusion)?

**If all three are YES** and the convergence mode is `fast`: skip remaining rounds and proceed directly to synthesis. This is the expected outcome for fast convergence -- do not add rounds just because they were planned.

**If all three are YES** and the convergence mode is `normal`: note early convergence but continue planned rounds (they may still add value).

**If any are NO**: continue to the next round as planned.

**Round 1: Initial Perspectives**
Each persona shares their view:
```
**[Persona Name]** ({archetype})
{Their perspective, concerns, suggestions}
```

*[Convergence check — proceed to synthesis if fast mode and criteria met]*

**Round 2: Building & Responding**
Personas respond to each other:
```
**[Persona Name]**
Building on [Other]'s point about X, I think...
I disagree with [Other] because...
```

*[Convergence check — proceed to synthesis if fast mode and criteria met]*

**Round 3 (optional): Convergence**
Find common ground and remaining tensions.

**After each round, persist transcript entries** for the session record. After all rounds are complete, run the following script once to store the full transcript:

```bash
wicked-garden run scripts/jam/save_transcript.py \
  --session-id "{session_id}" \
  --entries '{json_array_of_entries}'
```

Each entry in the JSON array must match this schema:
```json
{
  "session_id": "{session_id}",
  "round": 1,
  "persona_name": "Technical Architect",
  "persona_type": "technical",
  "raw_text": "...",
  "thinking": "...",
  "timestamp": "{ISO timestamp}",
  "entry_type": "perspective"
}
```

`persona_type` is one of: `technical`, `user`, `business`, `process`.

When recording persona contributions, include a `thinking` field capturing the persona's deliberative process — alternatives they considered, uncertainties they weighed, trade-offs they evaluated — before their final stated position in `raw_text`. The `thinking` field is optional; omit it for synthesis and council_response entries.

After synthesizing (step 4), append one final entry with `entry_type: synthesis`, `round: 0`, `persona_name: Facilitator`, and `raw_text` set to the full synthesis markdown.

If the script is unavailable, skip transcript storage silently and continue.

**After each round, emit an event** to the unified event log for cross-domain visibility:

```bash
wicked-garden python -c "
import os, sys; sys.path.insert(0, os.path.join(os.environ["WICKED_GARDEN_ROOT"], "scripts"))
from _event_store import EventStore
EventStore.ensure_schema()
EventStore.append(
    domain='jam',
    action='rounds.{round_number}.completed',
    source='sessions',
    record_id='{session_id}',
    payload={'round': {round_number}, 'personas': {persona_count}, 'topic': '{topic_summary}'},
    tags=['jam-round'],
)
"
```

After synthesis, emit a synthesis event:

```bash
wicked-garden python -c "
import os, sys; sys.path.insert(0, os.path.join(os.environ["WICKED_GARDEN_ROOT"], "scripts"))
from _event_store import EventStore
EventStore.ensure_schema()
EventStore.append(
    domain='jam',
    action='sessions.synthesized',
    source='sessions',
    record_id='{session_id}',
    payload={'topic': '{topic}', 'insights_count': {N}, 'confidence': '{HIGH/MEDIUM/LOW}'},
    tags=['jam-synthesis'],
)
"
```

If event emission fails, skip silently — it is supplementary, not required.

Also emit to wicked-bus (additive — both EventStore and bus).

**Payload rules**: IDs + counts + outcomes only — never persona dialogue, thinking text, or full prompts. Truncate any `topic` field to the first 80 characters before emitting.

At session start (emit `expected_persona_count` so the synthesis-trigger consumer knows when Round 1 is complete):
```bash
wicked-garden run scripts/_bus_emit.py wicked.garden.session.started '{"session_id":"{session_id}","topic":"{topic_truncated_80}","persona_count":{N},"expected_persona_count":{N}}' 2>/dev/null || true
```

After each Round 1 persona contributes (fire once per persona; Round 2 and beyond must NOT emit this event):
```bash
wicked-garden run scripts/_bus_emit.py wicked.garden.persona.contributed '{"session_id":"{session_id}","persona_name":"{persona_name}","round":1,"expected_persona_count":{N}}' 2>/dev/null || true
```

After synthesis:
```bash
wicked-garden run scripts/_bus_emit.py wicked.garden.session.synthesized '{"session_id":"{session_id}","insight_count":{N},"duration_secs":{D}}' 2>/dev/null || true
```

`expected_persona_count` equals the number of personas chosen in step 2 (Persona Assembly). Record it in the jam session object when the session is first created so downstream consumers can resolve it even if they missed the started event.

### 4. Synthesis

After rounds complete, synthesize:

```markdown
## Key Insights

1. **[Insight]** - {HIGH|MEDIUM|LOW} confidence
   - Supporting evidence from discussion
   - Caveats or conditions

## Action Items

1. [Prioritized action]
2. [Next steps]

## Open Questions

- [Unresolved tension or question]
```

For synthesis techniques (non-obvious connection, surprising agreement,
productive tension, missing voice) and the quality checklist, read
the `wicked-garden-jam` skill's `refs/synthesis-patterns.md`.

### 4.5. Multi-AI Perspective (Optional)

After the final persona round, if an external CLI (gemini, codex) is installed:

1. Send the topic + synthesis-so-far to ONE external AI
2. Frame as: "Given this discussion and synthesis, what perspective is missing? What would you challenge?"
3. Include the response as an additional perspective labeled **External AI ({tool name})**
4. Integrate the external viewpoint into the final synthesis

Skip this step if no external CLIs are available. This is graceful enhancement, not required.

### 5. Decision Record Storage

After synthesis, automatically store a structured decision record:

1. Store via the wicked-garden-mem skill (store action) — graceful degradation: skip if unavailable:
   ```
   Skill(skill="wicked-garden-mem", args="store \"Decision: {topic}\nChosen: {recommended option from synthesis}\nRationale: {key reasoning}\nAlternatives considered: {other options}\nConfidence: {HIGH/MEDIUM/LOW}\nEvidence used: {summary of evidence brief}\nPersonas: {list of personas}\" (kind=fact, about=[jam, decision, {2-3 topic keywords}])")
   ```
2. **If unavailable**: Show the decision record inline so users can manually save it

This creates organizational memory — every brainstorm becomes a searchable, recallable decision record.

## Output Structure

Put synthesis FIRST (context efficiency):

```markdown
## Brainstorm: {Topic}

### Key Insights
{Synthesis first - most important info}

### Action Items
{What to do next}

### Open Questions
{Unresolved items}

---

### Discussion Summary

#### Round 1
{Brief summary}

#### Round 2
{Brief summary}

### Personas
{Who participated}
```

## Rules

- **Genuine perspectives**: Each persona has legitimate concerns
- **No strawmen**: Even the "skeptic" makes valid points
- **Build, don't repeat**: Each round adds value
- **Synthesis matters**: Don't just summarize, distill insights
- **Evidence over opinions**: When evidence is available, personas cite it — "Based on the existing Redis implementation..." not "I think Redis might work"
- **Always store decisions**: After synthesis, store the decision record via the wicked-garden-mem skill (store action)

## Dispatch

Forked-context worker, reachable two ways:

- **Primary (skills-only):** invoke the skill by its frontmatter name — `wicked-garden-jam-brainstorm-facilitator` (used by the `wicked-garden-jam` skill's brainstorm sub-action).
- **Legacy delegation adapter (compat):** callers still emitting the pre-v12.25
  subagent form resolve here through the frontmatter `subagent_type:` compat key —
  `Task(subagent_type="wicked-garden:jam:brainstorm-facilitator")` maps to this fork skill.
