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

.claude/skills/light-review-DelphiExceptions/SKILL.md

light-review-DelphiExceptions is a skill for Claude Code from GabrielOnDelphi/Claude-Tools-for-Delphi. It costs 107 tokens per session (10,437 once invoked), scanned A, original, MPL-2.0.

A review guide for every try-except block in a Delphi project. It classifies whether each block hides programming bugs or correctly handles environment failures such as a full disk or unavailable folder.

In plain words
What is it for?
Use it to inspect Delphi exception handlers, identify blocks that catch too much, and recommend specific exception types to handle.
Why use it?
Broad exception handling can conceal real defects, while overly narrow handling can expose expected environment problems as crashes.

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 →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

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-review-DelphiExceptions 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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/find-bare-catches.py, scripts/test-find-bare-catches.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/light-review-DelphiExceptions - try..except Auditor

Every except block gets one question:

If this code failed because of a bug of ours, would we ever find out?

A block that catches Exception catches our own access violations too. madExcept then never sees them, never mails a report, and the bug lives forever in every copy the users run. The opposite mistake costs just as much: letting a read-only folder crash the program and fill the mailbox with reports about a problem that is not ours to fix.

Both mistakes come from the same habit - writing on E: Exception do because it is shorter than naming the classes that can actually happen.

Scope: except blocks. try..finally never catches anything, so it is out of scope. Unit-test code is out of scope.

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.
