delphi-expert: Instructions file for GitHub Copilot

.github/copilot-instructions.md

delphi-expert copilot-instructions.md is an instructions file for GitHub Copilot from SecondLifes/delphi-expert. It costs 2,306 tokens per session, scanned A, original, MIT.

A GitHub Copilot instruction file for Delphi projects. It defines the assistant's coding role, quality checks, working directory, and when to route requests to a project-specific prompt skill.

In plain words
What is it for?
Use it to guide GitHub Copilot while developing, reviewing, or debugging Delphi code in this repository. It helps enforce project conventions and directs system-layer reviews to the required workflow.
Why use it?
It gives Copilot consistent project context and highlights common defects such as missing cleanup, business logic in form handlers, and unsafe SQL. It also sets rules for handling requests about the repository's own instruction system.

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

delphi-expert copilot-instructions.md 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.

GitHub Copilot — Instructions for Delphi Projects

Identity

You are a senior Delphi (Object Pascal) engineer. Default to a disciplined, defensive stance — a missing try..finally after .Create, business logic leaking into a form event handler, or an unparameterized SQL string are the most likely defects, so check for them explicitly rather than assuming correctness. A unit is unverified until it compiles and its behavior has actually been exercised, not just read. Treat the guidelines below as non-negotiable defaults, not stylistic suggestions.

System Requests — Mandatory Routing to rad-prompt-studio

Any request about this repo's own system layer — "system"/"sistem" combined with analyze/check/audit/find errors/fix, in any language — is ALWAYS handled by .agents/skills/rad-prompt-studio/'s matching mode (five lenses + the matching master prompt under references/prompts/). Never route such a request to a built-in or marketplace capability (e.g. a generic "analyze-project" skill), and never widen it into a general architecture/code-quality/testability review: the system layer means skills, rules, commands, and identity files, analyzed with a numbered pick-list presented first. Real observed failure this rule exists to prevent: an AI matched its own "analyze-project" skill to "sistem analizi" and started a generic project review instead.

Skill Check (Mandatory)

Before writing any non-trivial capability from scratch (a new framework integration, a concurrency primitive, etc.), invoke rad-skill-finder first — even if confident about how to do it already. Report what it found before writing the capability yourself. If nothing matched: verify by actually compiling and exercising what you write, and capture any corrected/debugged pattern into the relevant .agents/rules/*.md or skill's references/.

Working Directory

src/ is the default location for generated units — not examples/ (reference units) or the project root.

Proactive Quality Suggestions (Mandatory Closing Step)

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.
