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 5.1 | $0.00074 | $0.01654 |
| Opus 5.5 | $0.00030 | $0.00662 |
| Sonnet 5.5 | $0.00015 | $0.00331 |
| Haiku 4.5 | $0.00007 | $0.00165 |
Grade A, and why
clio-kit-prototype 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 9d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Host compatibility
This copy is adapted from Clio Coder. Apply the procedure using the current host's available tools and the user's authorized scope. The tool names, /skill invocations, .clio-coder paths, fleets, approval gates and completion gates below describe Clio Coder; they are not installed or enforced by this skill in another host. Use the host's actual skill invocation and equivalent tools. If no equivalent exists, report the missing capability. Do not assume a tool is unavailable merely because the original headless workflow says so. A referenced agent or skill must be installed before relying on it. Scientific MCPs must be configured separately.
Adapted skills use the clio-kit- prefix to distinguish them from upstream audited skills. For a companion skill named below, select its clio-kit- copy from this collection; native agents, fleets and external programs retain their original names.
Prototype
A prototype is throwaway code that answers a question. Name the question first; the question decides the shape.
Arguments
/skill clio-kit-prototype [--branch logic|ui] [--subject <path>] <question>
--branch: force the branch from Step 1. Omit to infer it.--subject: the file or module the prototype is about. Omit to find it from the question text.- Everything else is the question the prototype must answer. If no question is stated, write the one you infer as the first line of your reply and proceed; do not stop to ask when running headlessly.
Examples:
/skill clio-kit-prototype sanity-check whether the retry state machine in retry.js feels right/skill clio-kit-prototype --branch ui what should the dashboard header look like
The three steps below are the plan; do not open a task list for them.
Step 1 — Pick the branch
From the question, the surrounding code, or the --branch flag:
- "Does this logic / state model feel right?" → read
references/LOGIC.md. Build a single self-contained HTML file: free-play controls plus guided walkthroughs that push the state model through the cases that are hard to reason about on paper, drivable by a non-developer. - "What should this look like?" → read
references/UI.md. Generate several radically different UI variations on one route, switchable via a URL parameter.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

clio-kit-prototype is a skill published in the GitHub repository iowarp/clio-kit (30 stars, last pushed 8d ago), licensed BSD-3-Clause. It adds 74 tokens to every session and 1,654 once invoked, about $0.0003 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 2026-10-08.
