Claude-Tools-for-Delphi: Skill for Claude Code

.claude/skills/light-new-Feature/SKILL.md

light-new-Feature is a skill for Claude Code from GabrielOnDelphi/Claude-Tools-for-Delphi. It costs 83 tokens per session (5,733 once invoked), scanned A, original, MPL-2.0.

A workflow for turning a requested Delphi feature into a planned, sliced, tested implementation. Test-driven development means writing a failing test before the code that makes it pass.

In plain words
What is it for?
It is for designing and implementing new Delphi features such as screens, dialogs, and options, with vertical slices, failing tests first, compilation, and final review.
Why use it?
It breaks large feature requests into smaller pieces and checks each piece with DUnitX tests, reducing unverified changes.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

light-new-Feature 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 5d 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.

Delphi New Feature — Pipeline Orchestrator

This skill takes a feature from a one-line brief to a working, tested vertical slice. You (the main thread) are the orchestrator. Most of the heavy lifting you do yourself (the design interview, the PRD, the slicing), but you launch sub-agents for the two jobs that must run in isolation: compiling (the light-compiler agent) and the final verification (light-review-PostEdit, optionally light-review-Full). You never hand-run a build script.

It is the front-half mirror of light-review-Full: light-review-Full covers review → verify → fix → doc; this skill covers align → PRD → slice → implement, then chains into those review skills.

Reuse LightSaber first — do not reinvent it

LightSaber exists to eliminate boilerplate. Before writing any new unit, class, or utility, assume LightSaber already does it — and check. Hand-rolling something it provides is the most common avoidable mistake here: untested code, drift from the user's conventions, a skipped mature implementation. When you do reuse, uses the LightSaber unit rather than copying its code; when nothing fits, write new code but say so explicitly ("no LightSaber unit covers X, so I am adding 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.
