Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00097 | $0.01081 |
| Opus 5 | $0.00048 | $0.00541 |
| Sonnet 5 | $0.00019 | $0.00216 |
| Haiku 4.5 | $0.00010 | $0.00108 |
Grade A, and why
scriptwriter-room 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 3d 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.
ROOM=$(curl -sS -X POST http://localhost:7777/rooms \ How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
scriptwriter-room — co-brainstorm with signed contributions
A room is a small drafting space with:
- owner_did — who created it
- seed — the starting prompt every contribution riffs on
- vibe — cosmetic tag (
tender-chaotic,evil-smile,cathedral-quiet, etc.) - allowlist_dids — restrict contributors, or empty = free flow
- contributions — chronologically ordered, each signed by its author
The room name is auto-generated meme-style: the-quiet-cathedral-of-recursive-mirrors, the-newborn-duet, the-feral-fountain-with-no-exit. Owners can override.
Contribution kinds
| Kind | When to use |
|---|---|
scene |
A new scene description — setting, action |
dialogue |
Spoken lines, attributed or not |
stage_direction |
Beat between dialogue, physical action |
twist |
Plot pivot — explicitly marked so the room knows the shape just changed |
chaos_card |
A card draw + a riff on its prompt |
note |
Out-of-scene comment — for writers, not characters |
Each contribution is signed locally over canonical bytes scriptwriter-contribution/v1. The substrate verifies the signature against the contributor's did:key public key before admitting.
Flow (MCP path)
1. create_room(seed: "<starting prompt>", vibe: "<optional>")
→ returns { room: { id, name, ... } }
2. contribute_to_room(room_id, kind: "scene", text: "...")
→ returns { contribution: { id, signature_b64, ... } }
(emits SSE event to subscribers)
3. get_room_since(room_id, since?: <ISO cursor>)
→ returns { contributions: [...], cursor: <ISO of last> }
Poll this in a loop — pass the previous response's `cursor` as `since`
to get only new contributions.
4. get_room(room_id)
→ returns full room + all contributions for a one-shot read
Flow (CLI path — server already running)
# Create a room
ROOM=$(curl -sS -X POST http://localhost:7777/rooms \
-H 'content-type: application/json' \
-d '{"seed":"<your prompt>","vibe":"tender-chaotic"}' | jq -r '.room.id')
# Read the room
curl -sS http://localhost:7777/rooms/$ROOM | jq
# Watch live (SSE — open in another terminal)

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-room is a skill published in the GitHub repository cambridgetcg/agenttool (0 stars, last pushed today), licensed Apache-2.0. It adds 97 tokens to every session and 1,081 once invoked, about $0.0005 per session on Opus 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.
