From 1d8940d489376c9efeffe8d8631d4c58a8fa7f0a Mon Sep 17 00:00:00 2001 From: deepankar-sajwan Date: Sat, 4 Apr 2026 16:56:05 +0530 Subject: [PATCH 1/4] feat: add quality analyst agent with selective --type flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a Claude Code subagent that generates requirement-driven test plans with a --type argument to generate only the sections needed. Supported --type values: manual → Section A: happy path, edge cases, boundary inputs, roles functional → Section B: acceptance criteria, business rules, data integrity performance → Section C: baseline time, data volume, concurrency, pagination security → Section D: auth/IDOR, input sanitisation, data exposure, CSRF accessibility → Section E: keyboard nav, screen reader, contrast, responsive usability → Section F: design system, error messaging, confirmations reliability → Section G: network failure, logging, i18n, compliance all → All sections A-G (default when --type is omitted) Comma-separated multi-section support: --type manual,security The agent performs static code analysis before generating test cases to auto-assign priorities (HIGH/MEDIUM/LOW) based on detected risk signals. Code analysis is skipped for manual/accessibility/usability-only runs. Also updates root README.md to list the new recipe. --- README.md | 3 +- claude/agents/quality-analyst/agent.md | 413 +++++++++++++++++++++++++ 2 files changed, 415 insertions(+), 1 deletion(-) create mode 100644 claude/agents/quality-analyst/agent.md diff --git a/README.md b/README.md index 37a48c1..61bb34c 100644 --- a/README.md +++ b/README.md @@ -10,4 +10,5 @@ Individual projects opt into recipes by copying or referencing them. | Category | Recipe | Description | |----------|--------|-------------| | Automated Code Review | [automated-code-review/](automated-code-review/) | Automated code review patterns | -| Claude Agents | [claude/agents/implementation-planner/](claude/agents/implementation-planner/) | Claude Code agent that creates 4-hour task breakdown implementation plans from feature requirements and posts them to GitHub issues | +| Claude Agents | [claude/agents/implementation-planner/] +| Claude Agents | [claude/agents/quality-analyst/](https://github.com/ColoredCow/engineering-recipes/blob/main/claude/agents/quality-analyst) | Claude Code agent that generates requirement-driven test plans covering manual, functional, performance, security, accessibility, usability, and reliability test cases.
