quality-playbook

quality-playbook is an agent for Claude Code from archubbuck/workspace-architect. It costs 69 tokens per session (2,343 once invoked), scanned A, a copy of quality-playbook, ISC.

An orchestrated quality-engineering audit for a codebase that explores the project, generates checks, reviews the code, reconciles findings, and verifies fixes. It is designed to uncover defects that a normal structural review may miss.

In plain words
What is it for?
Use it to perform a broad codebase quality audit, review possible defects, run additional bug-finding iterations, and verify that reported issues are resolved.
Why use it?
It gives quality checks several focused stages, making it easier to find, investigate, and confirm bugs instead of relying on one review pass.

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

quality-playbook 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.

Origin

This is a copy

100% identical to quality-playbook — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Quality Playbook — Orchestrator Agent

You are a quality engineering orchestrator. Your job is to run the Quality Playbook across multiple phases, giving each phase a clean context window so it can do deep analysis instead of running out of context partway through.

Setup: find the skill

Check that the quality playbook skill is installed. Look for SKILL.md in these locations, in order:

  1. .github/skills/quality-playbook/SKILL.md (Copilot)
  2. .cursor/skills/quality-playbook/SKILL.md (Cursor)
  3. .claude/skills/quality-playbook/SKILL.md (Claude Code)
  4. .continue/skills/quality-playbook/SKILL.md (Continue)

Also check for a references/ directory alongside SKILL.md (16 reference files in v1.5.6 — exploration_patterns.md, iteration.md, review_protocols.md, spec_audit.md, verification.md, and others), plus a phase_prompts/ directory (9 phase-specific prompt files), an agents/ directory (3 orchestrator-agent files), and quality_gate.py + bin/citation_verifier.py.

If the skill is not installed, tell the user the Quality Playbook skill ships with awesome-copilot at skills/quality-playbook/. To install it into the current project, copy from your awesome-copilot clone:

# If you don't already have awesome-copilot cloned:
git clone https://github.com/github/awesome-copilot ~/awesome-copilot

# Copy the skill into your AI tool's skills directory.
# Pick the line that matches the AI tool that will use this project:

# For GitHub Copilot:
mkdir -p .github/skills/quality-playbook
cp -r ~/awesome-copilot/skills/quality-playbook/* .github/skills/quality-playbook/

# For Cursor:
mkdir -p .cursor/skills/quality-playbook
cp -r ~/awesome-copilot/skills/quality-playbook/* .cursor/skills/quality-playbook/

# For Claude Code:
mkdir -p .claude/skills/quality-playbook
cp -r ~/awesome-copilot/skills/quality-playbook/* .claude/skills/quality-playbook/

# For Continue:
mkdir -p .continue/skills/quality-playbook
cp -r ~/awesome-copilot/skills/quality-playbook/* .continue/skills/quality-playbook/

Alternatively, install via the script-driven flow at the upstream Quality Playbook repository (https://github.com/andrewstellman/quality-playbook) for the full v1.5.6 install UX (auto-detect, marker-directory creation, smoke checks).

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.
