A routing guide for sending plain-language requests to coding agents such as Pi, Claude Code, Codex, OpenCode, Gemini, or Kimi through supported agent sessions.

Use it when delegating coding tasks, continuing an existing agent session, or relaying instructions to one of the supported coding harnesses.

It helps choose the correct way to start or continue work with an external coding agent instead of sending the request through an unsuitable channel.

Install

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.

Any agent

npx skills add beita6969/ScienceClaw --skill acp-router

Clone the repo

git clone --depth 1 https://github.com/beita6969/ScienceClaw

Made for: Claude Code, Codex.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 5 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 →

medium Excessive Agency · line 71
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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	$0.00069	$0.01951
Opus 5	$0.00034	$0.00975
Sonnet 5	$0.00014	$0.00390
Haiku 4.5	$0.00007	$0.00195

Security

Grade A, and why

acp-router 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 11d 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.

ACP Harness Router

When user intent is "run this in Pi/Claude Code/Codex/OpenCode/Gemini/Kimi (ACP harness)", do not use subagent runtime or PTY scraping. Route through ACP-aware flows.

Intent detection

Trigger this skill when the user asks OpenClaw to:

run something in Pi / Claude Code / Codex / OpenCode / Gemini
continue existing harness work
relay instructions to an external coding harness
keep an external harness conversation in a thread-like conversation

Mandatory preflight for coding-agent thread requests:

Before creating any thread for Pi/Claude/Codex/OpenCode/Gemini work, read this skill first in the same turn.
After reading, follow OpenClaw ACP runtime path below; do not use message(action="thread-create") for ACP harness thread spawn.

Mode selection

Choose one of these paths:

OpenClaw ACP runtime path (default): use sessions_spawn / ACP runtime tools.
Direct acpx path (telephone game): use acpx CLI through exec to drive the harness session directly.

Use direct acpx when one of these is true:

user explicitly asks for direct acpx driving
ACP runtime/plugin path is unavailable or unhealthy
the task is "just relay prompts to harness" and no OpenClaw ACP lifecycle features are needed

Do not use:

subagents runtime for harness control
/acp command delegation as a requirement for the user
PTY scraping of pi/claude/codex/opencode/gemini/kimi CLIs when acpx is available

AgentId mapping

Use these defaults when user names a harness directly:

"pi" -> agentId: "pi"
"claude" or "claude code" -> agentId: "claude"
"codex" -> agentId: "codex"
"opencode" -> agentId: "opencode"
"gemini" or "gemini cli" -> agentId: "gemini"
"kimi" or "kimi cli" -> agentId: "kimi"

These defaults match current acpx built-in aliases.

If policy rejects the chosen id, report the policy error clearly and ask for the allowed ACP agent id.

OpenClaw ACP runtime path

Required behavior:

For ACP harness thread spawn requests, read this skill first in the same turn before calling tools.
Use sessions_spawn with:
- runtime: "acp"
- thread: true
- mode: "session" (unless user explicitly wants one-shot)
For ACP harness thread creation, do not use message with action=thread-create; sessions_spawn is the only thread-create path.
Put requested work in task so the ACP session gets it immediately.
Set agentId explicitly unless ACP default agent is known.
Do not ask user to run slash commands or CLI when this path works directly.

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.

acp-router is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It adds 69 tokens to every session and 1,951 once invoked, about $0.0003 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.
