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 | $0.00091 | $0.01552 |
| Opus 5.5 | $0.00036 | $0.00621 |
| Sonnet 5.5 | $0.00018 | $0.00310 |
| Haiku 4.5 | $0.00009 | $0.00155 |
Grade C, and why
clio-kit-credentials scanned grade C with 1 finding 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- `.netrc` for data transfer is zero-access by default; leave it that way. How it starts
The opening of the file, as written. The whole thing — 131 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.
Credentials
Work with secrets without ever seeing them. Clio structurally blocks typed
reads and writes of secret-shaped paths (.env variants, ~/.ssh/, ~/.aws/,
key and pem files, netrc, kubeconfigs) by default. That net is on your side:
never attempt a shell workaround (cat, less, head, xxd, base64,
printenv, env, echo $VAR). Every attempt is audited, and any value that
slips into output lands permanently in the transcript and evidence bundles.
Presence Check
First identify the exact credential name the task actually needs: run the failing command or read its error output and docs. Error messages name the variable and often the issuer; never guess a name and never assume it matches an example. Then check presence, in strict preference order:
- Ask the user to confirm the credential is configured (
ask_userwhen active). Zero file access. credential_presentwith the exact credential name and source. Prefersource: "environment"for process variables and passfile: ".env"when the task names an env file. It returns only present/absent and which source was checked.grep -sq "^NAME=" <envfile>exactly, only if the typed tool is unavailable. Quiet mode, no output flags. The exit code answers the question; the value never enters context. The-qflag is the protocol, not a style choice.- There is no fourth option. Never verify by printing.
What ships with it
3 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-credentials is a skill published in the GitHub repository iowarp/clio-kit (30 stars, last pushed 8d ago), licensed BSD-3-Clause. It adds 91 tokens to every session and 1,552 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-08.
