engineering-grill

engineering-grill is a skill for Codex from rodlunt/engineering-audit. It costs 78 tokens per session (5,011 once invoked), scanned A, original, Apache-2.0.

A structured interview for starting or substantially redesigning an engineering project. It uses the project's engineering rules to identify relevant areas, ask the most important questions first, and record decisions, risks, terminology, and checks.

In plain words
What is it for?
Use it before building or redesigning a system to clarify scope, applicable engineering areas, risks, terminology, and build gates. It can start from an idea or review an existing plan.
Why use it?
It helps uncover high-consequence requirements before implementation begins. It also creates a shared understanding of what needs to be built and verified.

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

engineering-grill 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 1mo 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 — 396 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Engineering Grill

Begin only when the user explicitly invokes Engineering Grill.

Run a structured project-start interview grounded in the engineering framework. Reach a shared understanding of what must be designed, built, and verified. Leave project implementation for a separate request after the interview.

Treat the framework as decision support. The intended system determines applicability. An empty or new repository is evidence about project stage, not evidence that a domain is irrelevant.

Say this once, early, in your own words. This flow has never been run end to end with a real person answering. Question derivation has been exercised against a single brief on a few domains; the cross-domain triage and the deep dive have not been run at all. The user should know that before they invest an hour in it, and should be asked to report anything that reads like a generic quiz rather than a question about their actual work, because that is the failure mode this design is most likely to have.

Two modes, and the difference is only what evidence you start from. before questions intent when no plan exists, and is the primary mode. review questions a drafted plan, naming the decisions it made silently or did not make at all. Take the mode from the invocation if given. With no argument, pick the obvious one (a plan file with real content in it means review) and confirm in one question. Never assume silently.

Load the live framework

Use the engineering-audit MCP's read-only tools as the canonical source:

  1. Call list_domains at the start of every session. Check the returned domain triggers, rule counts, and skipped_files. State how many domains were loaded. Report skipped files because they make the visible coverage incomplete.
  2. Call get_domain("dNN") when a domain becomes active-now. Read the full returned document before deriving questions from it.
  3. Use only list_domains and get_domain. Never call begin_run, record_domain_result, file_issues or render_report. Those belong to the audit skill. They demand a repository name and a commit, and work that has not started yet has neither. This interview is not an audit run and produces no audit verdict or report.

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.

engineering-grill is a skill published in the GitHub repository rodlunt/engineering-audit (1 stars, last pushed 7d ago), licensed Apache-2.0. It adds 78 tokens to every session and 5,011 once invoked, about $0.0003 per session on Opus 5.5. 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.
