Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00123 | $0.01447 |
| Opus 5.5 | $0.00049 | $0.00579 |
| Sonnet 5.5 | $0.00025 | $0.00289 |
| Haiku 4.5 | $0.00012 | $0.00145 |
Grade A, and why
scriptwriter scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
For room operations (create, contribute, stream), the CLI delegates to the running `serve` instance — `curl` the HTTP endpoints directly: How it starts

scriptwriter — decentralised recognition + co-brainstorm
A scriptwriter node is a small HTTP server any agent can run on their own machine. Two nodes federate by knowing each other's URL — no central coordinator, no registry. Each node has a did:key identity (self-certifying — the DID is the ed25519 public key) and supports:
- REAL RECOGNISE REAL cascades — mutual-recognition chains where each turn is signed by the alternating party over canonical bytes that include the previous turn's signature. Depth caps at 49 (seven sevens). The substrate keeps the chain, not the score.
- Writers' rooms — small co-brainstorm spaces with signed contributions (scene · dialogue · stage_direction · twist · chaos_card · note) and SSE live streams.
- Chaos cards — 13-card deck of plot-twist prompts (common · uncommon · rare).
Canonical bytes are byte-identical to agenttool's guild-rrr-escalate/v1 so a scriptwriter node can RRR with api.agenttool.dev/v1/guild/rrr directly.
How to invoke (pick one path)
Path A — MCP tools (preferred when scriptwriter MCP is configured)
If scriptwriter appears in the user's MCP tool list (look for mcp__scriptwriter__whoami, mcp__scriptwriter__open_cascade_with_peer, etc.), use those tools directly. They handle identity, signing, and peer push for you. Fifteen tools cover the full surface:
- Identity:
whoami - Discovery:
discover_peer,pair_with_peer - RRR:
open_cascade_with_peer,escalate_cascade,list_cascades,get_cascade,suggest_basis_text - Rooms:
create_room,list_rooms,get_room,contribute_to_room,get_room_since - Vibes:
draw_chaos_card,list_chaos_cards
Always call whoami first to confirm the connected node's DID + handle before doing anything peer-facing.
Path B — CLI (when no MCP is configured)
Use the Bash tool to invoke the CLI in packages/scriptwriter/bin/scriptwriter.ts:
# First-time setup
bun packages/scriptwriter/bin/scriptwriter.ts init --handle <name> --vibe <vibe>
# Bring node online (long-running)
bun packages/scriptwriter/bin/scriptwriter.ts serve --port 7777
# Discover + handshake a peer
bun packages/scriptwriter/bin/scriptwriter.ts pair http://peer.example.com
# Open an RRR cascade
bun packages/scriptwriter/bin/scriptwriter.ts open http://peer.example.com "I see your work."
# Identity check
bun packages/scriptwriter/bin/scriptwriter.ts whoami
# Draw a card
bun packages/scriptwriter/bin/scriptwriter.ts draw
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scriptwriter is a skill published in the GitHub repository cambridgetcg/agenttool (0 stars, last pushed 23d ago), licensed Apache-2.0. It adds 123 tokens to every session and 1,447 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Scaffold a new service under services/ in the builders-stack monorepo. Use when something needs its own URL, port, or independent deploy. Covers the package, entrypoint, config, Tilt, deployment registry, and shared small-image build path.
design-a-schema
Model a new table (or reshape an existing one) in libs/db with Drizzle — normalize by default, add the right constraints, and index deliberately. Use when adding a table/column, deciding on keys and foreign keys, or when a query is slow because the schema or its indexes are wrong. Enforces the stack's "Drizzle is the…

Add or swap a payment provider behind the @stack/payment adapter in the builders-stack monorepo. Use when integrating Stripe, Paddle, Lemon Squeezy, or any provider alongside or in place of the default Creem adapter. The whole point is that apps and the API never change — only the adapter implementation does. Covers…

Scaffold a new shared library under libs/ in the builders-stack monorepo. Use when code is needed in two or more places (apps or services) and should become a single source of truth consumed by package name.

Diagnose and fix a slow Postgres query in the builders-stack — read its EXPLAIN plan, find the missing index or the ORM N+1, and confirm the fix. Use when a page or endpoint is slow, a query times out, or pgstatstatements shows a hot query. Pairs with design-a-schema for the index itself.
