What it does

Query Files is an agent skill from kylesnowschwartz/SimpleClaude. This skill SHOULD be used for structured extraction or batch queries against JSON (use jq), YAML (use yq), or Markdown (use mq), and for advanced text search with ripgrep flags or pipe composition (use rg).

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/jq-guide.md`, `references/mq-guide.md` and `references/rg-guide.md`).

It sits in Documents & Office, covering Document parsing and Markdown. The repository describes itself as: Practical minimalism for AI assisted programming with Claude Code.

When your agent uses it

  • Tasks that involve Document parsing
  • Tasks that involve Markdown

Example prompts

  • “/query-files”

Requirements

  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit a98f931. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq
    • rg
    • yq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Query Files loads about 1.2k tokens when it runs, and up to ~5.5k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 233 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 233 words (~1,187 tokens).

“Extract specific data from files using CLI tools instead of built-in Read/Grep. Saves 80-95% of context tokens on large files and enables features the built-in tools lack.”
