sumo-qa-suggesting-external-skill

sumo-qa-suggesting-external-skill is a skill for Claude Code, Codex from sumithr/sumo-qa. It costs 120 tokens per session (2,672 once invoked), scanned A, original, Apache-2.0.

A workflow for finding and using an external skill when the available QA workflows do not cover a testing need, or when source material must be converted first.

In plain words
What is it for?
It helps search for, optionally install, and hand off to an external skill for an unsupported QA capability or document-conversion task.
Why use it?
It provides a route for handling specialised QA requests without assuming that an existing workflow fits them.

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

sumo-qa-suggesting-external-skill 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 10d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Suggesting an external skill

Announce at start: "Checking external skills through sumo-qa — no native sumo-qa capability fits."

Output discipline (mandatory)

Inherits the global discipline from using-sumo-qa: output discipline (never surface internal taxonomy labels — including entry_kind — say "this needs a PDF-to-markdown converter first", not "entry_kind: conversion"), output economy (spend output on findings not framing; no preamble or self-narration; one question per turn; no closing pleasantries), knowledge authority hierarchy, internal scaffolding stays internal, and specialty-tool fit.

The Iron Law

The sumo-qa MCP server owns external-skill lifecycle. Search, install, local lookup, and execution handoff go through sumo_qa_search_external_skills, sumo_qa_install_external_skill, sumo_qa_check_external_skill_installed, and sumo_qa_execute_external_skill. Install is always gated on the user's explicit y. Never run sudo from this flow.

When to Use

Entered two ways, never cold; the mode is carried by entry_kind:

  1. entry_kind: qasumo-qa-deciding-approach found no native approach fits and the intent needs a tool/framework/QA surface sumo-qa doesn't natively cover (Playwright/Cypress E2E, accessibility audits, k6/Locust load, Pact contract tests, type checking, flaky-test quarantine).
  2. entry_kind: conversion — an ingestion source (PDF/PPTX/URL/docx reported unsupported_source) needs converting to markdown first. The gap is a converter, not a test tool.

Any install is gated by the per-candidate [y/N] prompt below; no global switch.

Checklist

You MUST work through these steps in order. External lifecycle operations are MCP tool calls, not host-shell npx calls.

  1. Check local install first. Call sumo_qa_check_external_skill_installed if the router or user named a likely skill. If found, call sumo_qa_execute_external_skill with the original intent and follow the returned skill_body. If that execute returns an isError, do NOT stop — fall through to step 2 and search for an alternative.

Changes

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.
