Firebird Database

Firebird Database is a skill for Claude Code, Codex from delphicleancode/lazarus-spec-kit. It costs 32 tokens per session (6,626 once invoked), scanned A, original, no licence file.

A set of development patterns for connecting FreePascal or Lazarus programs to Firebird, a relational database system. It covers database connections, Firebird's SQL language, transactions, and schema changes.

In plain words
What is it for?
Use it when building applications that store data in Firebird, including connection code, database migrations, generated number sequences, and transactions.
Why use it?
It gives you consistent approaches for common Firebird database tasks instead of requiring each project to invent its own structure.

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

Firebird Database 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.

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.
