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 | $0.17647 | $0.17647 |
| Opus 5.5 | $0.07059 | $0.07059 |
| Sonnet 5.5 | $0.03529 | $0.03529 |
| Haiku 4.5 | $0.01765 | $0.01765 |
Grade A, and why
igniteui-mcp-testbed CLAUDE.md scanned grade A with 0 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 7d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this is
A single-container appliance for exercising the Ignite UI AI toolchain (the Ignite UI CLI MCP server, the Theming MCP server, and the Agent Skills) against opencode. A small Express web wizard collects the user's choices, scaffolds an Ignite UI project, wires the AI config, and hands off to the opencode web UI. Each session runs in a fresh, ephemeral rootless Podman container.
This repo's logic (the MCP translation and server classification) is unit-/syntax-tested, but the README notes it has not been run end-to-end against real igniteui-cli / opencode / Podman — treat first builds as a shakedown, and expect the "adjust to your packages" spots (see below) to need tuning.
Commands
./run.sh build # podman build -t localhost/igniteui-testbed:latest .
./run.sh build --prune # build, then `podman image prune -f` to drop dangling <none> images
./run.sh # run a fresh ephemeral container; publishes ports 8080 / 4096 / 5000
./run.sh --matrix-config <file> # run with a matrix JSON config: bind-mounts it to
# /matrix-config.json, sets MATRIX_CONFIG, and (by default)
# auto-runs the matrix headlessly; the UI prefills from it
./stop.sh [<sess>] # stop running testbed container(s) (all, or one by session id)
# all four scripts take -h/--help/help (PowerShell: -Help, `help`, -? or Get-Help) and print usage
npm start # run the wizard backend directly (node src/server.ts), for host-side dev
npm run typecheck # tsc --noEmit gate over backend (tsconfig.json) + frontend (web/tsconfig.json)
npm run build:web # esbuild web/main.ts -> public/vendor/app.js (run alongside `npm start` for host dev)
npm run dev:web # build:web in --watch mode
npm run compare # scripts/compare-runs.mjs: side-by-side comparison page over
# sessions/history (routes x runs). --name/--since/--matrix to
# filter, --inline to embed the screenshots
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.

igniteui-mcp-testbed CLAUDE.md is an instructions file published in the GitHub repository IgniteUI/igniteui-mcp-testbed (50 stars, last pushed yesterday), licensed MIT. It adds 17,647 tokens to every session, about $0.0706 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
