Delphi Clean Code is a skill for Claude Code from delphicleancode/delphi-spec-kit. It costs 22 tokens per session (1,102 once invoked), scanned B, original, MIT.

A set of concise coding rules for Delphi, including naming, small methods, single-purpose classes, avoiding repetition, and choosing the simplest requested solution.

In plain words
What is it for?
It is for writing, reviewing, or refactoring Delphi classes, methods, variables, parameters, fields, and constants.
Why use it?
It gives an agent clear standards for producing code that is easier to read, review, and maintain. It also discourages unnecessary abstractions and duplicated logic.

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 B, and why

Delphi Clean Code scanned grade B with 1 finding 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

Delphi Clean Code — Skill

CRITICAL SKILL — Be concise, direct and solution-focused.

Fundamental Principles

Principle Rule
SRP A function/class does ONE thing
DRY Don't repeat code — extract and reuse
KISS Simplest solution that works
YAGNI Don't build what wasn't asked for
Boy Scout Leave the code better than you found it

Naming Rules (Pascal Guide)

Element Convention
Variables Reveal intent: LCustomerCount not N
Methods Verb + noun: GetCustomerById not Customer
Booleans Question form: IsActive, HasPermission, CanEdit
Constants SCREAMING_SNAKE: MAX_RETRY_COUNT
Fields Prefix F: FCustomerName
Parameters Prefix A: ACustomerName
Var. locations Prefix L: LCustomer

Rule: If you need a comment to explain a name, rename it.

Method Rules

Rule Description
Short Maximum 20 lines, ideal 5-10
One Thing Do one thing and do it well
One Level One level of abstraction per method
Few Args Maximum 3 arguments, prefer 0-2
No Side Effects Don't mute inputs unexpectedly

Code Structure

Standard Application
Guard Clauses Early returns for edge cases
Flat > Nested Avoid deep nesting (max 2 levels)
Composition Small compound methods
Colocation Related code together

Guard Clauses in Delphi

//❌ BAD — excessive nesting
procedure ProcessOrder(AOrder: TOrder);
begin
  if Assigned(AOrder) then
  begin
    if AOrder.Items.Count > 0 then
    begin
      if AOrder.IsValid then
      begin
        //real logic here
      end;
    end;
  end;
end;

//✅ BOM — guard clauses
procedure ProcessOrder(AOrder: TOrder);
begin
  if not Assigned(AOrder) then
    raise EArgumentNilException.Create('AOrder cannot be nil');
  if AOrder.Items.Count = 0 then
    raise EBusinessRuleException.Create('Order must have items');
  if not AOrder.IsValid then
    raise EValidationException.Create('Order validation failed');

  //real logic here — no nesting
end;
