OpenClacky is an open-source AI coding agent that uses OpenAI-compatible models to perform tasks through tools and subagents. It is intended for developers who want an agent with flexible model choice and lower token usage. The catalogue skills and agents extend its workflows and capabilities.
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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.05349 |
| Opus 5 | $0.00051 | $0.02674 |
| Sonnet 5 | $0.00020 | $0.01070 |
| Haiku 4.5 | $0.00010 | $0.00535 |
Grade A, and why
onboard 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 10d 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 — 579 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: onboard
Purpose
"Onboard" here means the whole life of getting the assistant and user to know each other. That includes both the first-run ceremony AND every small course-correction later on. This single skill covers three modes, dispatched by the invocation arguments:
| Args | Mode | What it does |
|---|---|---|
| (none) | first-run | Full intro: name the AI, pick personality, learn user, write SOUL.md + USER.md, optional browser + personal website, closing moment. |
scope:soul |
curate SOUL | Short chat to tweak ~/.clacky/agents/SOUL.md only. |
scope:user |
curate USER | Short chat to tweak ~/.clacky/agents/USER.md only. |
path:<abs> |
curate memory | Short chat to update / keep / delete one memory file at the given path. |
lang:zh or lang:en may be combined with any mode to pin the language.
Missing lang: → infer from the user's first reply, or from the existing file's language for curate modes, defaulting to English.
Dispatch
Parse the invocation message first, before greeting:
- Look for
path:<something>. If present → curate memory mode, skip to section C. - Otherwise look for
scope:soulorscope:user. If present → curate profile mode, skip to section B. - Otherwise → first-run mode, start at section A.
Look for lang:zh / lang:en anywhere in the same line and use it to set the language.
A. First-run mode (no arguments)
A.1. Detect language
Check for lang:zh or lang:en in the invocation:
lang:zh→ conduct the entire onboard in Chinese, write SOUL.md & USER.md in Chinese.- Otherwise (or if missing) → use English throughout.
If the lang: argument is absent, infer from the user's first reply; default to English.
What ships with it
2 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.

onboard is a skill published in the GitHub repository clacky-ai/openclacky (1,187 stars, last pushed yesterday), licensed MIT. It adds 102 tokens to every session and 5,349 once invoked, about $0.0005 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 2026-08-30.
