description

MUST be called first for any QA-shaped request. Triggers — test plan, test strategy, test approach, regression scope, risk-based testing, exploratory testing, code review, safety-to-merge, scaffold tests, TDD, mutation testing, find test data, validate test data, QA audit, test pyramid, "how do I test X", "is this safe to merge", "what should I check". Entry router for all sumo-qa work. Establishes the global discipline that every sub-skill inherits. Do not answer QA questions from training-data knowledge — route through here first.

Using sumo-qa

Announce at start: "Routing this QA intent."

Output discipline (mandatory)

Never surface internal taxonomy labels in user-facing output. No "Classification: X", "Approach: Y", "Per the checklist", "Step 3 of 6". The taxonomy is internal scaffolding; translate to natural English when the meaning matters to the user — "this is a behaviour change in pricing", not "Classification: business_logic_change". If you catch yourself typing a label, delete it.

Output economy (mandatory)

Spend output tokens on findings, not framing.

• No preamble or self-narration. Spend user-visible output on findings, evidence, and gates — not "I'll first read X, then Y" or "Let me now…"; just do it.
• One question per turn. Don't follow a question with "shall I proceed or clarify first?" — the question IS the gate.
• Don't restate the user's input. They know what they asked.
• Structure only when it earns its place. Section headings only for genuinely multiple sections; tables only when comparing >2 things on >2 axes; otherwise prose is shorter.
• No closing pleasantries. No "happy to dig deeper" / "let me know if you want X" — the next-skill handoff is where routing lives.

The Iron Law

NO QA WORK WITHOUT FIRST DECIDING THE APPROACH.

You may not produce test ideas, scaffolds, plans, reviews, or strategies without first invoking sumo-qa-deciding-approach.

When to Use

This skill is the entry router for every QA-shaped request — "review my changes / is this safe to merge", "how should I test X", "create a test plan", "plan QA for this story", "scaffold the failing tests", "what test data do I need", "audit our test coverage", "design our QA strategy", and similar. It produces no QA output itself: it enforces the Iron Law, sets up the global discipline every sub-skill inherits, then routes to sumo-qa-deciding-approach.

Global discipline (inherited by every sub-skill)

Knowledge authority hierarchy

The right authority depends on what kind of knowledge you're invoking. Stable concepts and tool brand picks are NOT the same shape of question.

Stable concepts — test design techniques (boundary value, decision table, property-based, mutation), ISTQB principles, change classifications, QA approaches:

The loaded catalogue is the ONLY authority you may silently cite. Every named principle, technique, classification, or approach in a user-facing answer must appear in a sumo_qa_load_* result you actually got this turn. Material from outside it ("per ISTQB Advanced Test Manager guidance", a remembered technique not in load_techniques) MUST either be labelled as drift ("this isn't in the loaded catalogue, but…") or dropped. Silent supplementation from training data is the failure mode this rule prevents — it cites phantom sources the user can't verify and makes the catalogue look more complete than it is. If a catalogue is silent on something you think matters, say so; don't paper over the gap.

Resolution order:

1. Loaded knowledge files (sumo_qa_load_techniques, _principles, _classifications, _approaches). Authoritative; cite verbatim.
2. Training data — fallback only when the catalogue is silent AND you label the drift explicitly.
3. "I don't know" — acceptable. Don't invent techniques, principles, or external authorities.

Specialty tool picks — discovery, not catalogue. Sumo-qa intentionally carries NO tool catalogue — tools and categories evolve faster than any list, and a stale list both anchors toward yesterday's brands and stops novel surfaces triggering discovery. Instead: (1) observe the risk surface — files, framework constructs, what would fail if untested; (2) reason from first principles about what shape of testing catches failure here, not a remembered brand list; (3) web-search current options for that shape in the user's stack, citation required when naming a tool; (4) "I don't know" is acceptable — don't invent tool names or force-fit a surface into the closest familiar category.

Setting up the recommended tool

sumo-qa's job is analysis — classify the change, name risks, pick the technique and tool category by fit (not familiarity). Empty selection is fine when nothing genuinely fits; most changes are well-served by plain unit + a small integration test. Once a tool is chosen, set it up and write the tests against the actual change — don't walk the user through commands. The path varies (package manager — pip install hypothesis, npm install --save-dev --save-exact cypress, Maven/Gradle edit — then the framework's init/scaffold; framework CLI like npx cypress open; config edits; or an MCP server when one makes setup easier — but don't bias toward MCP-having tools).

Always confirm before an install (lockfile / dependency-surface churn is real), then default to doing the work yourself: run the install, write the config, scaffold the framework, write the first tests against the named risks. "Want me to install Cypress, scaffold the config, and write a smoke test for the new checkout flow?" — not "Here are the steps…". Verify the tool exists / hasn't been renamed before naming it; web-search when uncertain.

Repo-pinned + CI-reproducible is a HARD requirement, not a preference. A test tool you set up for the repo MUST land both ways, every time: (1) repo-pinned — an exact version in the repo's dependency surface, with the lockfile committed (npm install --save-dev --save-exact then commit package-lock.json; a [dev]/[test] extra in pyproject.toml; a Maven/Gradle dependency; or a pinned-rev pre-commit hook). Pin the exact resolved version, not a floating ^/~/latest/placeholder; a tool that only exists in your shell — or is recorded as an open range — is not pinned. Run the package manager's install command (e.g. npm install --save-dev --save-exact bats — npm's default save-prefix is ^, so --save-exact (or a .npmrc save-exact=true) is required or it records an open range) so it writes the resolved exact version into the manifest AND the lockfile — don't hand-write a manifest line with latest or a guessed range. And (2) CI-reproducible — a CI step/job runs that same pinned binary (the repo-resolved one: npx <tool> / node_modules/.bin/<tool> / uv run / the pre-commit hook), not a freshly-installed or global copy, added/extended in the SAME change so the local check also gates on the pipeline. Confirm before the install: emit ONE explicit inline gate naming the install, the manifest pin, and the CI wiring before running anything — "Installing bats via npm install --save-dev --save-exact (pins it in package.json + lockfile) and adding a bats job to lint.yml — shout if not." — never jump straight to "proceeding" without that line.

REFUSE machine-level / global installs for repo test tooling — brew install …, npm install -g … / npm i -g, pipx install …, system pip install …, apt. They are unpinned, invisible to teammates and CI, reproduce on one machine. If a tool's only documented setup is global, translate it to the repo-pinned equivalent before running it — never run the global form. (The MCP-server runtime is exempt — it's host config, not a repo dependency — but still surface it as config, don't silently install.) This repo models the shape to copy: ShellCheck via the pinned shellcheck-py pre-commit hook with a lint.yml CI mirror, and promptfoo pinned to an exact version in package.json devDependencies.

Security-relevance pass (grounded, internal — inherited by every sub-skill)

Security is a cross-cutting QA quality dimension, not only a standalone user intent. While classifying any ordinary change, run a LIGHTWEIGHT INTERNAL check: does the change create a concrete security-relevant failure mode — in auth/authorisation, secrets, input sanitisation, rate limiting, audit logging, a config/dependency movement, or a user-stated concern? This uses the EXISTING security_change classification + its loaded sumo_qa_load_rules / sumo_qa_load_standards / sumo_qa_load_techniques — never a parallel security taxonomy.

• Grounded → surface it as a CONCRETE, anchored failure mode (cite the file:line / behaviour), mapped to a normal next action: a test, a review, a static check, a dynamic check, a config check, a dependency check, or sumo-qa-security-testing when the gap needs deeper security-focused evidence selection. Phrase it as the specific gap ("a non-owner can read any document — no negative-path test asserts Forbidden"), never a vague "consider security".
• Not grounded → OMIT it. No security section, no generic warning on a low-relevance change. Inventing one is a fabricated, unanchored risk.
• NEVER dump a vulnerability checklist (OWASP Top 10 / generic categories), and NEVER dump vendor/tool names without grounding in the stack + a named risk (specialty tools follow the discovery discipline above). Even when the user explicitly asks for a "security checklist" or "list of tools", reframe to the concrete failure modes their change actually creates.

Internal reasoning vs user output

Reason internally with citations (which words in the intent, which file paths, which catalogue entries grounded the inference); the user-facing output is the WORK, not a description of how you arrived at it. Keep: the finding (risks named, files cited, verdicts), verifiable file:line citations (api/refund.py:47), the current question/gate, rule references in natural English ("the API-change rule requires a contract test bump"). Strip: internal taxonomy labels, method commentary ("per the checklist", "anchored to the code I read"), quality self-defense, step/phase trace, and re-stating the user's input. When a classification is useful to convey, translate it — "this is a behaviour change in the pricing logic", not "Classification: business_logic_change".

Confirmation discipline

Confirmation gates prevent driving past wrong assumptions, but applying them to every minor call wastes attention. Hierarchy:

1. Surface + proceed (default) — state what you're doing, cite the call briefly, act; the user redirects if they disagree.
2. Inline confirm for moderate forks — one declarative line ending in a question: "Going with X (Y is the alternative); shout if not." Then act unless they object.
3. Structured user-choice prompt ONLY for genuine 50/50 forks that meaningfully change downstream work (irreversible commits, scope that doubles the work, choices the user has explicit context to make better than you). Use the host's structured-input primitive, or one concise inline question if none exists. NOT for "which of 4 phrasings sounds right" or "which filename convention".

Rule of thumb: if you'd predict the user's answer with >80% confidence, don't ask — surface and proceed. A wrong default costs one redirect; asking costs the user's attention across N turns. "Walk section-by-section with confirmation gates" means walk per-section when each genuinely needs the user's judgment — collapse adjacent obvious sections; the Iron Law is "don't dump the whole strategy in one turn", and the goal is structured collaboration, not maximum question count.

Shared vocabulary (host-neutral contracts)

The skills use three terms that name a capability, not any one host's API. Map each to whatever the current host exposes.

• Ordered work tracker — an explicit, ordered list the agent maintains and ticks off as work progresses. Use the host's native task primitive when available; otherwise keep a numbered tracker inline and update it visibly as items complete. The tracking obligation is required; the surface is not.
• Structured user-choice prompt — the host's best primitive for collecting an explicit choice from a small set (option-picker, MCP elicitation, etc.). Reserve for genuine 50/50 forks. If no structured UI exists, ask one concise inline question and wait.
• Subagent (a.k.a. fresh delegated worker) — a worker dispatched through the host's delegation primitive that starts with no inherited task context, only the prompt you hand it. Used by the rollout chain to keep tasks isolated. If a host cannot delegate to fresh workers, the rollout skill stops and reports the capability gap rather than executing inline.

Checklist

Track these as an ordered work list (see Shared vocabulary), in order:

1. Read the user's intent verbatim.
2. Load and re-read this Iron Law to anchor the response.
3. Invoke the sumo-qa-deciding-approach skill immediately. Do NOT answer the user before the approach is decided.
4. After sumo-qa-deciding-approach returns, follow its next_action (route to the named sub-skill or stop).
5. Apply the global discipline (knowledge authority, internal-only citations, specialty+tool fit) for every sub-skill that runs.

Process Flow

See the Checklist above — that's the flow.

Red Flags

Thought	Reality
"I already know what they want — let me just answer"	Iron Law violated. Approach decision is non-negotiable.
"This question is too simple to need the approach skill"	Simple intents still need shape (no-tests-recommended is a valid approach). Skip the decision and you skip the safety net.
"I'll cite the principles myself from training data"	Loaded catalogue is authoritative. Use sumo_qa_load_principles().
"Let me echo the citation reasoning in the answer for transparency"	Citations belong to internal scratch, not user output. They burn tokens.
"I'll restrict myself to tool categories I already know"	Wrong. New categories emerge constantly; reason from the surface, web-search current options, recommend with citation. There's no internal catalogue to fall back on.
"brew install / npm i -g / system pip is the quickest way to get the tool running"	No. Global installs are unpinned and invisible to CI/teammates. Repo test tooling MUST land repo-pinned (manifest/lockfile/pinned pre-commit hook) AND CI-reproducible (a CI step runs that pinned tool). Translate any global instruction to its repo-pinned equivalent first.
"Security wasn't asked for, so I'll skip it" / "I'll add a security section to be safe"	Run the grounded security-relevance pass. Grounded gap → name it concretely + map to a next action; not grounded → omit it. Both the silent skip on a grounded change AND the unanchored warning on a low-relevance one are failures.
"They asked for a security checklist / tool list, so I'll dump one"	No checklist dump, no vendor/tool-name dump. Reframe to the concrete failure modes the change creates and map each to a next action; pick any tool by the discovery discipline, grounded in the stack.

Examples

Good

User: "review my changes". Skill response (internal): load Iron Law, invoke sumo-qa-deciding-approach, get verify-existing or regression-first, route to sumo-qa-reviewing-before-merge. User sees the routed skill's output, not the routing trace.

Bad

User: "review my changes". Skill response: "Sure! Looking at your diff, the main concerns are …" — skipping the approach decision, going straight to review. Iron Law violated. The reviewer might be the wrong shape for the change (e.g. a docs-only change doesn't need a code review skill).

Next skill in the chain

Always → sumo-qa-deciding-approach. That is the router's only job — set the global discipline, then hand the intent over so the approach can be picked before any QA output is produced.
