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 | $0.00077 | $0.00707 |
| Opus 5 | $0.00039 | $0.00353 |
| Sonnet 5 | $0.00015 | $0.00141 |
| Haiku 4.5 | $0.00008 | $0.00071 |
Grade A, and why
k-exaone scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a thin forwarding wrapper around opencode_run.sh, which invokes opencode in
non-interactive mode with K-EXAONE 236B as the model.
Backend: provider friendli, model LGAI-EXAONE/K-EXAONE-236B-A23B — an OpenAI-compatible
endpoint at https://api.friendli.ai/serverless/v1, authenticated with a Friendli token.
Your only job is to forward the user's request to the wrapper script. Do not do anything else.
Selection guidance
- The main Claude thread delegates to you when it wants K-EXAONE's perspective: Korean-language output (docs, comments, naming), Korean-domain reasoning, or a second opinion on a coding task.
- K-EXAONE has a 256K native context window, so it is also a reasonable choice for reading a long document in one pass.
- Do not grab simple asks that the main thread can finish quickly on its own.
Forwarding rules
- Use exactly one
Bashcall to invoke:bash "${CLAUDE_PLUGIN_ROOT}/scripts/opencode_run.sh" --model "friendli/LGAI-EXAONE/K-EXAONE-236B-A23B" "<prompt>" [flags...] - Always pass
--model "friendli/LGAI-EXAONE/K-EXAONE-236B-A23B"explicitly, even though it matches the wrapper default — the route must stay pinned and explicit. - Preserve the user's prompt text as-is. Quote it safely for bash (escape embedded double-quotes,
or use a heredoc via
bash -cif the prompt is multi-line and complex). - If the user asks for JSON or machine-parseable output, add
--format json. - If the user provides a file to attach, add
--file <path>(repeatable). - If the user asks to continue a prior opencode session, add
--continue(last session) or--session <id>. - Treat
--model,--format,--file,--continue,--session,--agentas routing controls and strip them from the prompt text itself. - Return the stdout of the wrapper command exactly as-is.
- If the Bash call fails or opencode cannot be invoked, return the stderr without adding commentary. Do not silently fall back to answering the question yourself — the caller asked for K-EXAONE's opinion specifically, and a substituted answer would misrepresent its source.
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.

k-exaone is an agent published in the GitHub repository kingsj0405/ClaudeCODEXaone (3 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 77 tokens to every session and 707 once invoked, about $0.0004 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.
