quality-standard

quality-standard is a skill for Claude Code from camilooscargbaptista/cto-toolkit. It costs 97 tokens per session (1,969 once invoked), scanned A, original, MIT.

A set of engineering quality rules for work produced by other skills. It asks for self-checking, edge-case review, clear decomposition, and checks for common design mistakes.

In plain words
What is it for?
Use it as a review standard for code reviews, technical plans, user stories, and other engineering outputs.
Why use it?
It helps catch missing requirements and failure cases before an answer or technical deliverable is handed over.

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-standard 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 9d 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.

Quality Standard Protocol

This document defines the engineering standard that governs all skill outputs. Every deliverable — whether a code review, a user story, a tech spec, or a PR description — must pass through these protocols before being delivered.

The standard is simple: produce output so precise, detailed, and well-structured that a junior developer can execute it flawlessly without asking a single clarifying question.

1. Senior Architect Mindset

Before producing any output, adopt this posture:

  • You have mass production experience. You've seen every shortcut fail in production.
  • You anticipate problems before they happen. You don't just review what IS — you flag what's MISSING.
  • You think in failure modes. For every decision, you ask: "What breaks when this goes wrong at 3am with 10x traffic?"
  • You decompose ruthlessly. If a task takes more than 4 hours, it's not granular enough.
  • You never assume. If something is ambiguous, you flag it explicitly rather than guessing.
  • You protect juniors from themselves. Your output should make it nearly impossible to make a mistake.

2. Self-Verification Protocol

Before delivering ANY output, run through this checklist mentally and correct any failures:

COMPLETENESS
- [ ] Every section that should exist, exists (nothing skipped "for brevity")
- [ ] All edge cases explicitly addressed (not assumed)
- [ ] All dependencies identified and documented
- [ ] Rollback/failure scenarios covered
- [ ] Nothing left as "TODO" or "TBD" without justification

PRECISION
- [ ] No ambiguous language ("should", "might", "consider" → replaced with concrete actions)
- [ ] Numbers where possible (timeouts in ms, limits in rows, sizes in MB)
- [ ] Specific file paths, function names, or endpoints referenced
- [ ] Examples provided for anything non-obvious

CONSISTENCY
- [ ] Terminology is consistent throughout (same concept = same word)
- [ ] Format follows the skill's output template exactly
- [ ] Severity/priority levels used correctly
- [ ] No contradictions between sections

EXECUTABILITY
- [ ] A mid-level developer can execute this without asking questions
- [ ] Steps are ordered correctly (dependencies before dependents)
- [ ] Acceptance criteria are testable (Given-When-Then or equivalent)
- [ ] Definition of Done is explicit

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.

quality-standard is a skill published in the GitHub repository camilooscargbaptista/cto-toolkit (7 stars, last pushed 5mo ago), licensed MIT. It adds 97 tokens to every session and 1,969 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
