regression-testing

regression-testing is a skill for Claude Code, Codex from upex-galaxy/agentic-qa-boilerplate. It costs 174 tokens per session (10,619 once invoked), scanned A, original, MIT.

A workflow for running regression tests, which check that existing features still work after code changes, through continuous-integration pipelines.

In plain words
What is it for?
It starts test runs, monitors them, examines failure artifacts, classifies failures, and reports a GO, CAUTION, or NO-GO result.
Why use it?
It turns test results and failures into a clear release decision instead of leaving developers to interpret scattered logs themselves.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; names the AskUserQuestion tool; installed under .agents/ (shared by several agents).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is gh run download <RUN_ID> -n merged-allure-results-staging -D ./analysis/.

Good fit It starts test runs, monitors them, examines failure artifacts, classifies failures, and reports a GO, CAUTION, or NO-GO result.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

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

regression-testing 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 3d 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 — 560 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Forbidden invocations

NEVER invoke /sdd-* skills from this workflow. SDD is an optional user-installed ceremony; this skill ships self-contained and does not chain SDD under any condition. If you need to refactor KATA, fixtures, cli/, scripts/, or api/schemas/ pipeline, exit this skill first and invoke /framework-development — which itself runs Plan → Code → Verify → Archive natively (no SDD required).

This boundary is mechanical, not advisory: scripts/lint-skills.ts rejects any /sdd- mention outside this section. See: .agents/skills/agentic-qa-core/references/skill-composition-strategy.md §4 (governs users who manually install SDD).

Regression Testing — Execute, Analyze, Decide

Orchestrates the full release-readiness pipeline: trigger a CI suite, monitor it to completion, classify failures, score against release criteria, and emit a GO / CAUTION / NO-GO verdict plus a stakeholder report.

Three phases, always in this order: Execute → Analyze → Report. Do not skip analysis and jump to a report. Do not guess classification without reading failure logs.


Inputs

  • .github/workflows/*.yml — workflow files for regression / smoke / sanity suites; defines triggers, inputs, and artifact uploads.
  • .context/master-test-plan.md — regression Epic key + expected pass-rate SLOs per suite.
  • playwright.config.ts — reporter config, retry policy, project matrix; needed to interpret retry counts and shard splits.
  • Previous run's Allure report (artifact URL or local download under ./analysis/previous/) — baseline for trend computation.
  • kata-manifest.json — registry of tests and ATCs available; used to cross-reference failed test IDs.
  • .agents/jira-required.yaml — Jira refs (project key, work types, transitions) for filing regression issues.
  • agentic-qa-core/references/defect-management-doctrine.mdcanonical authority for classifying (Bug/Defect/Improvement), the mandatory field matrix, QA-Assignee ownership, and the QA process epic when a confirmed regression is filed in Jira (Phase 3). Read BEFORE filing any defect.

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.
