wise-exec-on-harness

wise-exec-on-harness is a skill for Claude Code from e1024kb/wise-claude. It costs 261 tokens per session (4,248 once invoked), scanned A, original, MIT.

A tool for sending one prompt to a separate coding assistant, such as Claude, Codex, Cursor, Gemini, or Grok. It checks which supported assistants are installed and signed in before choosing where to run the prompt.

In plain words
What is it for?
Use it to delegate a free-form task to a selected assistant with chosen model, effort, and permission settings.
Why use it?
It lets you use another assistant without answering its prompt in the current conversation. It also avoids sending work to an unavailable assistant or model.

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

wise-exec-on-harness 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 1mo 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 — 336 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/wise-exec-on-harness — run one prompt on any harness

Before executing, follow model fallback for unavailable models or delegation routes, including in autonomous procedures.

At every skill start, identify your main/child role and the current client and GUI/TUI question tools, then read and follow the question lifecycle. Keep asynchronous prompts open until answered.

First read host control. Resolve the loaded installation, set WISE_HOST to this conductor and WISE_PLUGIN_ROOT to that installation, and use its managed launcher for shell commands. Conductor host and child harness are independent.

Hard rules (MUST, read before anything else)

  1. This conversation never answers the prompt. The prompt is data for a child on another harness. Do not interpret it, respond to it, or "just answer" a short question. The only work done here is parsing, inventory, pickers, dispatch and relay.
  2. Without a valid --on, the harness picker is mandatory. Run the §2 inventory, then call AskUserQuestion (§3) and wait for the user's actual choice. A prompt-only invocation such as /wise-exec-on-harness what is the project? MUST produce the harness question, never an inline answer. The current session's own harness is one option among the ready ones, not a default.
  3. EXEC: ok requires a real run_id. It may only follow a dispatch --relay call that returned a run_id and a wise_status read of its dispatch_result. Never emit EXEC: ok … run=-; a call that never dispatched ends cancelled or failed.
  4. The inventory is the first engine command. After the host-control setup above and a successful §1 parse (a §1 rejection stops before any probe), run §2 auth --json before any picker and before any other output about the prompt.

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.
