oc

oc is a command for coding agents from kckylechen1/ClankerHouse. It costs 20 tokens per session (850 once invoked), scanned A, a copy of codex, MIT.

A command that sends a task to the Opencode agent through Claude’s agent system and returns its result. It can pass a model choice and optionally allow file changes in a worktree, a separate working copy.

In plain words
What is it for?
Use it to delegate coding or other agent tasks to Opencode, choose a model, and optionally run the task with permission to edit files.
Why use it?
It removes the need to manually start Opencode, wait for it, and copy its response back. It also standardises how model and write options are passed.

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.

Token cost

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.

Security

Grade A, and why

oc 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 4d 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.

Origin

This is a copy

81% identical to codex — 26 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Dispatch the task below to the Clanker: Opencode by invoking the clanker:oc subagent via the Agent tool (subagent_type: "clanker:oc"). The subagent is a zero-discretion relay: it calls clanker_dispatch_start once and long-polls clanker_wait until the turn completes, its transcript showing the progress digests. Its final message (final_message + result fields) is what you relay to the user.

Raw request: $ARGUMENTS

Argument mapping (resolve these, then pass explicit parameters to the subagent):

  • Model token (first token if it is a shortname, or a --model value): pass it through as model unchanged — the server resolves shortnames from the single source in src/constants.ts (OC_MODEL_ALIASES). For reference, the current map is glm → zhipuai-coding-plan/glm-5.2, ds → deepseek/deepseek-v4-pro, kimi → kimi-for-coding/k2p6, free → opencode/deepseek-v4-flash-free; a value containing / is a full id. If no model token is given, default to glm.
  • --write present → read_only: false and a worktree is mandatory (the server rejects a write without one). If the user did not name a branch, generate a default worktree like clanker/oc-<short-timestamp>. Absent --write (or --read-only present) → read_only: true (safe default; the Clanker cannot modify files, no worktree needed).
  • --effort <effort>effort. Note: the opencode ACP lane does not support a reasoning-effort override; the lane returns a warning and ignores it (surfaced verbatim).
  • Everything that is not a recognized flag or the model token is the natural-language prompt. Do not forward the flags themselves as prompt text.
  • --background and --wait are Claude execution flags. Do not forward them to the Clanker prompt, and do not treat them as part of the natural-language task text.

Execution mode:

  • If the raw request includes --wait, run the clanker:oc subagent in the foreground and relay its final result verbatim.
  • If the raw request includes --background, run the clanker:oc subagent as a Claude Code background task with run_in_background: true.
  • If neither flag is present, default to background. The whole point of this command is that Claude Code owns the visible Clanker task row; the MCP server only owns the ACP backend.

Background flow:

  • Launch exactly one Agent tool call with subagent_type: "clanker:oc" and run_in_background: true.
  • The task text must be: "Dispatch as this Clanker. prompt=. read_only=. worktree=. model=<token, e.g. glm or zhipuai-coding-plan/glm-5.2>. effort=. Follow your relay protocol."
  • Do not call MCP dispatch tools in the main conversation.
  • Do not wait for the subagent or relay a final result in this turn.
  • After launching, tell the user: "Clanker: Opencode started in the Claude Code background task list."

Foreground flow:

  • Launch exactly one Agent tool call with subagent_type: "clanker:oc" and no background flag.
  • Use the same task text as the background flow.
  • Relay the subagent's final result verbatim.

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.
