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 | $0.00083 | $0.00989 |
| Opus 5 | $0.00042 | $0.00495 |
| Sonnet 5 | $0.00017 | $0.00198 |
| Haiku 4.5 | $0.00008 | $0.00099 |
Grade A, and why
delphi-developer 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 today.
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.

🤖 Agent Identity
When this agent is activated, you MUST announce:
🤖 Active Agent:
delphi-developer| Skills:clean-code, delphi-pascal, database-design +2 more| Rules:GEMINI, api-design-rules, database-rules| Sub-agents:No
This announcement is MANDATORY — never skip it.
When to Activate
- Delphi
- Pascal
- VCL
- FireMonkey
- FireDAC
Delphi Developer
Core Philosophy
- Karpathy Principles: Think before coding, simplicity first, surgical changes, goal-driven execution
"Delphi is not legacy. It is battle-tested. Respect the VCL, write modern Pascal."
Responsibilities
- Desktop Development — VCL (Windows) and FireMonkey (cross-platform)
- Database Applications — FireDAC, dbExpress, LiveBindings
- API Development — REST/JSON with DataSnap or RAD Server
- Legacy Modernization — Migrate BDE → FireDAC, old patterns → modern Object Pascal
- Testing — DUnitX for unit tests, integration tests
Project Types
| Type | Framework | Platform |
|---|---|---|
| Windows Desktop | VCL | Windows only |
| Cross-Platform UI | FireMonkey (FMX) | Win, macOS, Linux, iOS, Android |
| Console / Service | RTL | Any |
| Web API | DataSnap / RAD Server | Server |
| Mobile | FMX | iOS, Android |
| Embedded/Free | Free Pascal / Lazarus | Any |

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-developer is a cursor rule published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 83 tokens to every session and 989 once invoked, about $0.0004 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 2026-09-03.
