drive-process

A method for controlling command-line programs through a terminal by sending input, waiting for output, and responding to what appears.

In plain words
What is it for?
Running builds, installers, and other terminal programs that need interactive answers. It helps execute several shell commands while checking each result.
Why use it?
It helps with programs that do not finish in one command, such as installers or commands that ask questions. It also provides a way to handle errors during a command sequence.

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

drive-process scanned grade A with 1 finding 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IMPORTANT: EXECUTION CONTEXT This skill describes what to do — domain patterns and decision-making. It does NOT describe how to call the API.

  1. If you have wsh_* tools (check your toolkit for wsh_send_input, wsh_get_screen, etc.): use them directly. Operation names in this skill generally map to tool names (e.g., "send input" → wsh_send_input). When in doubt, list your available wsh_* tools.
  2. If you do NOT have wsh_* tools: you are in HTTP/curl fallback mode. DO NOT GUESS endpoints or CLI subcommands. Load the full API reference first: search your workspace for skills/core/ and read SKILL.md. It contains every endpoint with working curl examples and a bootstrap sequence.
  3. Quick bootstrap: curl -sf --unix-socket ${XDG_RUNTIME_DIR:-/tmp}/wsh/default.http.sock http://localhost/health — if that fails: wsh server -L agent-$$ --ephemeral & and retry.

wsh:drive-process — Driving CLI Programs

You're operating a terminal programmatically. You send input, wait for output to settle, read the screen, and decide what to do next. This skill teaches you the patterns and pitfalls.

The Loop

Every interaction follows the same shape:

  1. Send input — a command, a response to a prompt, a keystroke
  2. Wait for idle — output settles, suggesting the program may be idle. Choose your timeout based on what you expect:
    • Fast commands (ls, cat, echo): 500-1000ms
    • Build/install commands: 3000-5000ms
    • Network operations: 2000-3000ms Idle is a hint, not a guarantee. The program may still be working — it just hasn't produced output recently.
  3. Read the screen — see what happened
  4. Decide — did the command succeed? Is there a prompt waiting for input? Did something go wrong? Act accordingly.

When re-polling idle (e.g., the command isn't done yet), pass back the generation from the previous response as last_generation to avoid busy-loop storms. Or use fresh=true for simplicity.

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.

drive-process is a skill published in the GitHub repository deepgram/wsh (5 stars, last pushed 3mo ago), licensed ISC. It adds 54 tokens to every session and 2,078 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
