Roleplay Sim

Custom Scenario Format

Instead of the hardcoded "web app rewrite" scenario, users can provide a JSON scenario file. When start rp is invoked with a file path argument, load and validate it.

Action Types Reference

File Actions — Simulating Real Work

Agents should produce actual files during the simulation to make it feel realistic. All file operations happen inside the /tmp/fl-sim/ project directory.

• mkdir: Create directories for agent workspaces (e.g., src/api/, docs/architecture/)
• write_file: Agent writes a .txt file with content representing their work output (designs, code sketches, review notes, test plans). The agent field is narrated as the author.
• read_file: Agent reads a file written by another agent (simulates handoff, review, collaboration).

Rules:

• Only .txt files — safe, simple, no execution risk
• Paths are relative to /tmp/fl-sim/ (the simulation project root)
• File writes pair naturally with reserve/release — reserve the glob before writing, release after
• Narrate file operations as part of the story: "Alice writes her API design to docs/api-spec.txt"

Execution:

# mkdir
mkdir -p /tmp/fl-sim/src/api

# write_file
cat > /tmp/fl-sim/src/api/routes.txt << 'EOF'
GET /users - List all users
POST /users - Create user
GET /users/:id - Get user by ID
EOF

# read_file
cat /tmp/fl-sim/src/api/routes.txt

Name Resolution

Entity names in the scenario file are resolved to slugs at runtime. The simulation:

1. Creates all entities during setup
2. Captures slug mappings (name -> slug)
3. Replaces <name> references in cycle actions with actual slugs

Validation

On load, validate:

• All task names referenced in blocks exist in tasks
• All agent names referenced in cycles exist in agents
• All task names referenced in cycles exist in tasks
• All module names referenced in relates_to exist in modules
• All task names referenced in owns exist in tasks
• Each cycle has at least one action
• No duplicate entity names across all types

If validation fails, report errors and do not start the simulation.

Loading a Custom Scenario

When start rp <path> is invoked:

1. Read and parse the JSON file
2. Validate the schema (report all errors, not just the first)
3. Announce: "Loading custom scenario: <name> — <description>"
4. Run the standard setup (build, init temp project)
5. Create entities from the scenario definition (modules, agents, tasks, docs, plans)
6. Set up relations (blocks, owns, relates_to, depends_on)
7. Capture all slug mappings
8. Execute cycles in order, narrating each one

Built-in Scenarios

Scenario files are in scenarios/ relative to this skill:

Default Scenario

If start rp is invoked without a file path, use scenarios/web-app-rewrite.json.

State File: /tmp/fl-sim/rp-state.json

The state file enables session survival. Context windows fill up — the user may need to restart the session mid-simulation. The state file preserves everything needed to resume.

State file format

{
  "last_completed_cycle": 3,
  "next_cycle": 4,
  "slugs": {
    "api-gateway": "a1b2c3d4",
    "auth-service": "e5f6g7h8",
    "data-layer": "i9j0k1l2",
    "frontend": "m3n4o5p6",

    "auth-design": "u3v4w5x6"
  },
  "notes": "Cycle 3 ended with implement-auth blocked. Two escalations pending."
}

Save state (on pause rp)

After completing the current cycle, write the state file:

cat > /tmp/fl-sim/rp-state.json << 'STATEEOF'
{ ... current state ... }
STATEEOF

Resume (on start rp when state file exists)

1. Check for /tmp/fl-sim/rp-state.json
2. If it exists, read it and announce: "Resuming simulation from cycle N"
3. Load the slug mappings from the state file — do NOT re-seed
4. Run fl list --type task --status all to show current state
5. Continue from next_cycle

What to capture in state

• All entity slug mappings (name → slug)
• Last completed cycle number
• Free-text notes about what happened (for narrator context)

Prerequisite

The fl binary must be on PATH. Build with:

make build CRATE=all RELEASE=1

Setup Phase (on start rp)

1. Build and init

make build CRATE=all RELEASE=1
cd /tmp && rm -rf fl-sim && mkdir fl-sim && cd fl-sim
fl init

2. Load and seed scenario

Load the scenario JSON (default or user-provided), then for each section:

1. Modules: fl add <name> --type module --summary "<summary>" for each
2. Agents: fl add <name> --type agent --summary "<summary>" for each
3. Tasks: fl task add <name> --summary "<summary>" --priority <N> for each
4. Docs: fl add <name> --type doc --summary "<summary>" for each
5. Plans: fl add <name> --type plan --summary "<summary>" for each
6. Blocking relations: For each task with blocks, run fl relate <task> blocks <blocked-task>
7. Plan ownership: For each plan with owns, run fl relate <plan> owns <task>
8. Doc relations: For each doc with relates_to, run fl relate <doc> relates_to <module>
9. Extra relations: For each entry in extra_relations, run fl relate <source> <type> <target>

Capture all slugs from creation output — you need them for cycle actions.

3. Verify seed

fl list --type task --status all
fl list --type agent
fl list --type module
fl task ready

Narrate: show the dependency structure and which tasks are initially unblocked.

4. Execute cycles

For each cycle in the scenario:

1. Announce the cycle title and narrate the scene
2. Execute each action, resolving entity names to slugs
3. For reserve actions that are expected to fail (conflict demonstrations), narrate exit code 6 as correct behavior
4. After all actions, summarize what changed

Cleanup Phase (on end rp)

rm -rf /tmp/fl-sim

Summary template

Print a summary of what was demonstrated:

## Simulation Summary

**Entities created:** 18 (4 modules, 4 agents, 8 tasks, 1 plan, 2 docs)
**Relations created:** ~20 (blocks, depends_on, owns, relates_to, assigned_to)
**Messages sent:** ~12 (text, artifact, blocker, question)
**Escalations raised:** 3 (2 blockers, 1 question) — all resolved
**Reservation conflicts:** 1 — correctly prevented
**Export/import:** verified round-trip integrity

### Patterns demonstrated:
1. Dependency chain — tasks unblock sequentially as predecessors close
2. Escalation workflow — agents raise blockers/questions, humans respond
3. File reservations — advisory locking prevents conflicts
4. Inter-agent messaging — direct async communication
5. Graph queries — context, critical-path, ready-task computation
6. Data portability — export/import preserves full state

Pause Behavior (on pause rp)

1. Stop after the current cycle completes
2. Write the state file to /tmp/fl-sim/rp-state.json with:
   • last_completed_cycle: the cycle number just finished
   • next_cycle: the next cycle to run
   • slugs: all entity name → slug mappings
   • notes: brief narrator context (what happened, any pending escalations/blockers)
3. Print:
   • What cycle just finished
   • What the next cycle would be
   • Current system state (open tasks, pending escalations, active reservations)
4. Tell the user: "State saved. You can restart the session and say start rp to resume from cycle N."
5. Ask: "Want to continue, skip ahead, or adjust anything?"

Resume Behavior (on start rp when /tmp/fl-sim/rp-state.json exists)

1. Read the state file
2. Announce: "Resuming from cycle N. Here's where we left off: [notes]"
3. Load slug mappings — do not re-create entities
4. Run fl list --type task --status all and fl escalations to show current state
5. Continue from next_cycle
6. The cwd must be /tmp/fl-sim/

CLI Reference

IMPORTANT: Always invoke /filament before running simulation commands. The filament skill contains the complete CLI reference with correct syntax. Key pitfalls:

• fl task assign SLUG --to AGENT (--to required)
• fl message send --from A --to B --body "..." --type text (all flags required)
• fl reserve "glob/**" --agent SLUG (quote the glob)
• fl search "query" --type lesson (query is first positional arg)

For multi-agent dispatch via tmux + claude -p, see the filament skill's "Multi-Agent Dispatch" section.

Important Notes

• All slugs are dynamic — capture them from fl add output and use them throughout
• Don't fabricate CLI output — run the actual commands and narrate based on real results
• The simulation runs in /tmp/fl-sim/ — completely isolated, won't affect the main project
• No daemon needed for single-session mode — all cycles use direct CLI commands
• Daemon required for multi-agent mode — fl serve before launching concurrent agents
• Exit code 6 on reservation conflict is expected, not an error — narrate it as the system working correctly
• State file enables session restart — always save state on pause rp so a new session can resume
• On resume, trust the state file — don't re-run setup or re-seed entities, just continue from the saved cycle
