query is a skill for Claude Code, Codex from lambdalisue/cclens. It costs 75 tokens per session (718 once invoked), scanned A, original, no licence file.

A skill for answering specific questions about Claude Code usage with read-only SQL queries against the cclens data store. SQL is a language for asking structured questions of stored data.

In plain words
What is it for?
Use it to find frequently failing files, common tool errors, monthly usage, or other custom slices of Claude Code session data.
Why use it?
It lets you investigate detailed usage patterns that fixed reports may not show, without changing the stored records.

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

query 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.
