sumo-qa-reviewing-before-merge

sumo-qa-reviewing-before-merge is a skill for Claude Code from sumithr/sumo-qa. It costs 84 tokens per session (17,084 once invoked), scanned A, original, Apache-2.0.

A pre-merge review guide for checking code changes before they are combined into the main project. It examines the diff and changed files, runs tests, and reports risks and a verdict.

In plain words
What is it for?
Use it to review a change, investigate what could break, run verification, and decide whether the code is ready to merge.
Why use it?
It prevents a change from being called safe to merge without fresh test evidence. It also surfaces product questions that cannot be answered from the code diff alone.

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-reviewing-before-merge 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.

How it starts

The opening of the file, as written. The whole thing — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reviewing before merge

Help the user decide whether a change is safe to ship by walking the review one section at a time: explore the diff, surface what was found, name the risks, run the verification, deliver the verdict. The user has product context (was this a deliberate behaviour change? is this consumer used externally?) the AI can't infer from the diff alone — surface it through questions, don't assume it.

Announce at start: "Reviewing the diff against fresh test evidence."

Output discipline (mandatory)

Inherits the global discipline from using-sumo-qa: output discipline (never surface internal taxonomy labels — say "behaviour change in pricing", not "Classification: business_logic_change"; this includes the raw keys of any loaded change-rules file — cite the rule in plain English, e.g. "the documented-inventory rule", never by echoing its YAML key), 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

NEVER CLAIM SAFE-TO-MERGE WITHOUT FRESH VERIFICATION EVIDENCE. "All tests pass" is necessary but not sufficient — every named risk must also have a passing test covering it.

Evidence-backed gate reporting

Every gate claim you surface — the suite verdict, each named risk's coverage, the safe-to-merge call — carries a status (passed / failed / skipped / blocked / unverified) and, unless skipped or unverified, cites the ONE observed evidence item backing it by source (command, tool_call, file_read, user_fact, external_ci, manual_observation). Citing means NAMING the source and quoting the observation — for the suite verdict, label the source type and quote the verification command verbatim with its counts, e.g. Evidence (command): $ pytest tests/auth -q → 42 passed, 2 skipped. Test names or counts alone, with no labeled source behind them, do NOT count as a cite. A passed / failed / blocked claim with no cited source is an overstatement; unverified is the honest state when nothing was observed this turn. SAFE TO MERGE is a passed safe-to-merge gate — unreachable while any gate is failed / blocked / unverified (step 10, restated as a status). Keep it compact: a status word + a short source cite per line, never a second dump.

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.
