logic-programmer

logic-programmer is a skill for Claude Code from Pyroxin/opinionated-claude-skills. It costs 53 tokens per session (3,857 once invoked), scanned A, original, EPL-2.0.

A set of ways to design programs around relationships, rules, and constraints instead of step-by-step instructions. It covers logic languages such as Prolog, miniKanren, Datalog, OWL2, and Answer Set Programming.

In plain words
What is it for?
Use it when building or reviewing logic-programming systems, or when applying rule-based and constraint-based design in applications that use more than one programming style.
Why use it?
It helps when ordinary control-flow code makes relationships and rules difficult to express or reason about. These patterns can make constraint-heavy problems clearer.

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

logic-programmer 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 9d 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.
