What is cli-opencode?

A command-line controller for OpenCode, an external coding agent that can run delegated tasks and parallel sessions.

It is for cross-agent coding, parallel implementation, and tasks that use OpenCode's plugins, skills, or connected tools.

It lets the current agent hand off work while preserving a clear separation between the coordinating agent and the delegated session.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.09765
Opus 5	$0.00015	$0.04882
Sonnet 5	$0.00006	$0.01953
Haiku 4.5	$0.00003	$0.00976

Security

Grade C, and why

cli-opencode scanned grade C with 2 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.

OpenCode CLI Orchestrator - Full-Runtime Cross-AI Dispatch

CRITICAL — SELF-INVOCATION PROHIBITED

This skill dispatches to the OpenCode CLI binary (opencode). If the agent currently reading this skill is itself running inside OpenCode (TUI / acp / serve / run modes — detection signals listed in §2), the skill MUST refuse to load and return the documented error message instead of generating any opencode invocation. The only exception is an explicit "parallel detached" request that intentionally spawns a SEPARATE session with its own session id and state directory.

A running CLI skill never dispatches itself. The cli-X skills are for cross-AI delegation only — never self-invocation.

Orchestrate OpenCode's opencode run from external AI assistants (Claude Code, OpenCode, raw shell) AND from inside an existing OpenCode session for parallel detached workers. Three documented use cases keep the cycle risk explicit while giving every dispatch path a copy-paste invocation shape.

Core Principle: The calling AI stays the conductor. Delegate to OpenCode for what it does best — the full plugin, skill, and MCP runtime in a one-shot dispatch. Validate and integrate the output.

1. WHEN TO USE

Activation Triggers

Full plugin / skill / MCP runtime (use case 1) — calling AI is Claude Code / OpenCode / Copilot / raw shell AND the task needs the project's spec folders and continuity docs, or every plugin/skill/MCP tool in a one-shot dispatch. Includes @deep-research / @deep-review agent loops with externalized state under .opencode/specs/.
Parallel detached session (use case 2) — operator already inside OpenCode (TUI / web / serve / acp) AND wants a SEPARATE session with its own session id and state directory for ablation, worker farm, or parallel research. Prompt explicitly mentions "parallel detached", "ablation suite", "worker farm", "parallel research", "spawn detached", or "share URL".
Agent dispatch — task matches a specialized OpenCode agent. Primary agents (directly invokable via --agent): general, plan (built-in), orchestrate. Generic subagents fully dispatched via the orchestrate primary: context, review, write, debug, ai-council. Command-owned loop executors (deep-research, deep-review, deep-improvement, prompt-improver) are owned end-to-end by their parent /deep:* command; orchestrate may perform exactly one bounded hand-off dispatch to a recognized loop request, but never manages the loop itself. See §3 "OpenCode Agent Delegation" for the full contract.
Cross-repo dispatch — session in repo A dispatches into repo B's plugin/skill/MCP runtime via --dir <path> or remote OpenCode server via --attach <url>.

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.

cli-opencode is a skill published in the GitHub repository MichelKerkmeester/skilled-agent-harness_spec-driven-loops (35 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 9,765 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
