A broad software-engineering skill covering architecture, test-driven development, bug diagnosis, code review, security checks, and interface design.

Use it for engineering tasks such as planning features, writing tests, diagnosing bugs, reviewing code, checking defensive security, and designing interfaces.

It provides a structured set of practices for handling software changes, investigations, reviews, and design work.

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.

Model	Per session	Once invoked
Fable 5	$0.00110	$0.04864
Opus 5	$0.00055	$0.02432
Sonnet 5	$0.00022	$0.00973
Haiku 4.5	$0.00011	$0.00486

Security

Grade A, and why

engineer 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 yesterday.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/arch_report.py, scripts/brand_picker.py, scripts/generate_tokens.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Universal Master Engineering & Design Skill

A unified, production-grade standard for software engineering craftsmanship, deep system architecture, defensive zero-trust security, and UI/UX design excellence. Synthesizes decades of software design principles (Ousterhout, Beck, Evans, Pragmatic Programmer) with 74 real-world production design systems across 8 archetypes and the 17-category Vibe-Check defensive security standard.

The Master Engineering & Design Lifecycle

Every feature, interface, and system follows a disciplined, traceable progression:

What ships with it

35 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

Subscribe to this mod's changes

engineer is a skill published in the GitHub repository kk376/dev-suite (0 stars, last pushed yesterday), licensed MIT. It adds 110 tokens to every session and 4,864 once invoked, about $0.0006 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.
