compiler-7b229a7d

compiler-7b229a7d is a skill for Claude Code from FuRongJun-1999/dsh-memory. It costs 104 tokens per session (478 once invoked), scanned A, original, MIT.

A bytecode encoder and decoder for compact representations using variable-length integers. Bytecode is the lower-level instruction data produced by a compiler.

In plain words
What is it for?
Use it when converting compact bytecode values to and from their encoded form.
Why use it?
It reduces the space used by suitable integer values and provides matching encode and decode operations. It does not apply to invalid byte values or unsupported modes.

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

compiler-7b229a7d 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 today.

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.
