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 | $0.00058 | $0.02176 |
| Opus 5.5 | $0.00023 | $0.00870 |
| Sonnet 5.5 | $0.00012 | $0.00435 |
| Haiku 4.5 | $0.00006 | $0.00218 |
Grade C, and why
launch-demo scanned grade C with 2 findings 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 2mo 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Launch the KB Platform demo
The demo is a Docker Compose stack (docker-compose.demo.yaml, 16 services) fronted by a
Next.js web app on http://localhost:3000. Everything is driven through the Makefile.
Never call docker compose without -f docker-compose.demo.yaml — the compose file is
non-default, so a bare docker compose finds no services.
One command
make demo
make demo is the idempotent "make me demo-ready" target. It:
- pre-cleans stopped containers from previous runs,
- brings the stack up if it's down (
docker compose up -d --build, rebuilds only changed images), - (re-)seeds the demo data — 50 docs, 8 templates, 5 drafts, ~80 audit events,
- prints the URL and what to try.
Safe to re-run between demos without losing state. On success it prints:
Web: http://localhost:3000 (logged in as demo user — all groups)
Script: demo/demo-script.md (14-step printable cue card)
Build time: a cold image cache (first-ever run, or after make reset) can take anywhere
from a few minutes to ~an hour — the mcp-server / torch-pulling services dominate. A warm
stack finishes in well under a minute. On Windows, prefer plain build output for backgrounded
builds: docker compose -f docker-compose.demo.yaml build --progress=plain (BuildKit TTY
output is lossy when redirected).
Sub-option: run on your personal Claude account — no API key (SUPPLY_PROXY=1, WP-31)
To make the Chatbot + draft generation work without an ANTHROPIC_API_KEY, route the
demo's LLM calls through your own Claude subscription via the opt-in claude-proxy:
make demo SUPPLY_PROXY=1
It reads your Claude OAuth token once on the host (~/.claude/.credentials.json; never mounted
into a container), starts an in-network proxy (claude-proxy:3456) that forwards to
api.anthropic.com under that token, and fails the demo loudly if the token is rejected
(with a "validate your token … or set ANTHROPIC_API_KEY" message). A real ANTHROPIC_API_KEY
(env or .env) always wins and skips the proxy.
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.

launch-demo is a skill published in the GitHub repository Syntax753/synkb (0 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 58 tokens to every session and 2,176 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
