claudish-usage

claudish-usage is a skill for Claude Code from MadAppGang/magus. It costs 50 tokens per session (10,465 once invoked), scanned A, original, MIT.

A guide for running AI models through Claudish's MCP tools, including individual runs, long-lived sessions and panels of models working on one prompt. It also explains how to find models and handle structured results and errors.

In plain words
What is it for?
Use it when working with Claudish, OpenRouter or external AI models, including comparing models, running a panel, starting a session or reporting an error.
Why use it?
It removes guesswork about which Claudish tool or model identifier to use. Structured results make model failures easier to inspect and act on.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

claudish-usage 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 yesterday.

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.

Claudish Usage Skill

Purpose: How agents run models — external and native — through the claudish MCP tools Status: Production Ready

Everything runs through the MCP tools

There is no CLI tier and no "direct usage" tier. Every model run goes through a claudish MCP tool — one model or a panel, external or native, inside /team and /delegate or anywhere else. Bash("claudish ...") is not a fallback, not a shortcut for a small task, and not acceptable "just this once".

You need Tool
A panel of models on one prompt, in parallel team
One model, long task, its own tools and working directory create_session
One model, one completion, no tools and no session run_prompt
What models exist right now list_models, search_models
Capability comparison between models compare_models
Report a failure to claudish's developers report_error

Two properties are why: MCP sessions run in their own process, so a model's transcript never enters your context window; and every tool returns a structured per-slot result with status and errors, so a failure is data you can act on rather than text you have to parse. Both are lost the moment you shell out.

The only CLI that survives is a set of three read-only diagnostics — see "Diagnostics: the only CLI left". They investigate the runtime. They never run a task.

Quick Start

Step 1: Install the runtime (once)

npm install -g claudish     # or: bun add -g claudish

This installs the runtime, not a way to run tasks. The plugin's .mcp.json starts the MCP server by launching this binary with --mcp, so it must be on PATH or the tools below do not exist at all. Restart the session after installing so the server registers.

Step 2: Find out what models exist right now

list_models()                      → current recommended set, pricing, capabilities, access lines
search_models({ query: "kimi" })   → every live variant in one family

claudish-usage is a skill published in the GitHub repository MadAppGang/magus (9 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 10,465 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
