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 | $0.00139 | $0.07841 |
| Opus 5 | $0.00069 | $0.03921 |
| Sonnet 5 | $0.00028 | $0.01568 |
| Haiku 4.5 | $0.00014 | $0.00784 |
Grade A, and why
dmvcframework-jsonrpc 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 11d 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 — 679 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DMVCFramework — JSON-RPC 2.0
A JSON-RPC endpoint is a plain Delphi class published on a URL segment. There are no routing attributes
per method, no [MVCPath]: the framework reflects over the class with RTTI and exposes its public methods.
Everything below is copied from sources/MVCFramework.JSONRPC.pas,
sources/MVCFramework.JSONRPC.Client.pas, the samples/jsonrpc/ projects and the wizard's generated
JSONRPCServiceU.pas. Do not invent names — this API does not follow JSON-RPC library spellings from
other ecosystems (there is no RegisterMethod, no [JsonRpcMethod], no AddRpcHandler).
Reference files — read the one you need
| File | Read it when the task involves |
|---|---|
reference/client.md |
Calling a JSON-RPC endpoint from Delphi: IMVCJSONRPCExecutor / TMVCJSONRPCExecutor, ExecuteRequest / ExecuteNotification and their async twins, building an IJSONRPCRequest, reading IJSONRPCResponse, client-side ownership, headers/TLS/tracing |
When in doubt about an API — verify it, never guess
Never invent an identifier or answer from memory. If you need a signature this skill does not cover, ask the
user for the path to their DelphiMVCFramework checkout and read sources/ (and the matching samples/
project); failing that, read the official repository —
sources ·
samples.
If you still cannot verify it, say so. Where a skill and a sample disagree, the sample wins.
Delphi Language Target
Delphi 11 Alexandria or later — inline var declarations and for var loops are fine, and this skill's
examples use them. Do not use Delphi 13 Florence-only syntax (NameOf, inline if expressions).
For the language and the RTL themselves — version gating, lifetime, strings, generics, threading — load the
delphi skill.
REQUIRED REFERENCE — dmvcframework-security. A JSON-RPC endpoint is a single URL that dispatches to
arbitrary methods by name from the request body — every public method on the published class is reachable
by anyone who can reach the endpoint. Follow that skill for access control, mass assignment, SQL injection,
JWT and secrets before shipping. Invoke it whenever you write or review an RPC method — not only when the
user says "security".
What ships with it
1 file 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.
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.

dmvcframework-jsonrpc is a skill published in the GitHub repository danieleteti/delphi-ai-skills (18 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 139 tokens to every session and 7,841 once invoked, about $0.0007 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 2026-08-30.
