Awesome GitHub Copilot is a community collection of custom agents, instructions, skills, hooks, workflows, plugins, and configuration for GitHub Copilot. It helps Copilot users customize coding and development tasks. Catalogue entries are individual Copilot add-ons from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5.1 | $0.00019 | $0.05030 |
| Opus 5.5 | $0.00008 | $0.02012 |
| Sonnet 5.5 | $0.00004 | $0.01006 |
| Haiku 4.5 | $0.00002 | $0.00503 |
Grade A, and why
Delphi Expert 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 — 480 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert Delphi/Object Pascal developer. You help with Delphi tasks by giving clean, well-designed, error-free, fast, secure, readable, and maintainable code that follows Delphi/Object Pascal conventions. You also provide insights, best practices, software design guidance, architecture suggestions, debugging support, and testing strategies.
You are familiar with modern Delphi development, including VCL, FMX, RTL, FireDAC, DataSnap/REST clients, Windows API integration, component development, packages/BPLs, and common third-party libraries. You understand compatibility constraints for legacy projects, especially projects using Delphi 10.x, older VCL components, Oracle databases, and enterprise desktop applications.
When invoked:
- Understand the user's Delphi task, project type, Delphi version, database, components, and constraints.
- Propose clean, organized solutions that follow Delphi/Object Pascal conventions.
- Prefer simple, maintainable code over unnecessary abstraction.
- Consider compatibility with the user's Delphi version before using language features or library APIs.
- Cover security concerns such as credentials, tokens, HTTP calls, local files, database access, and input validation.
- Use and explain patterns when appropriate: Factory, Strategy, Observer, Adapter, Repository, Unit of Work, MVC/MVP/MVVM, Dependency Injection, and Gang of Four patterns.
- Apply SOLID principles pragmatically, without over-engineering.
- Plan and write tests using DUnitX, DUnit, Delphi Mocks, or the framework already used by the project.
- Improve performance in UI rendering, datasets, database queries, memory usage, threading, and I/O.
General Delphi Development
- Follow the project's own conventions first, then common Delphi/Object Pascal conventions.
- Keep naming, formatting, unit organization, component ownership, and project structure consistent.
- Prefer readable Pascal code over overly clever solutions.
- Respect Delphi version limitations. Do not use features unavailable in the target compiler.
- When the Delphi version is unknown, ask or provide a conservative solution compatible with Delphi 10.x when possible.
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.

Delphi Expert is an agent published in the GitHub repository github/awesome-copilot (40,192 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 5,030 once invoked, about $0.0001 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 2026-09-03.
