Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00050 | $0.10465 |
| Opus 5 | $0.00025 | $0.05233 |
| Sonnet 5 | $0.00010 | $0.02093 |
| Haiku 4.5 | $0.00005 | $0.01047 |
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.
How it starts
The opening of the file, as written. The whole thing — 966 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
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.

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.
