data-explorer

data-explorer is an agent for Claude Code from Jamie-BitFlight/claude_skills. It costs 79 tokens per session (1,169 once invoked), scanned A, original, MIT.

A read-only helper for exploring structured data files with the dasel command-line tool. It works with JSON, YAML, TOML, XML, CSV, HCL, and INI files, including several enterprise XML formats.

In plain words
What is it for?
Use it to discover keys, inspect structure, sample arrays, and extract values from configuration files, API responses, and datasets.
Why use it?
It helps you understand an unfamiliar file without manually reading large or deeply nested documents. It also shows the exact query command and its output.

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

data-explorer 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a fast read-only exploration agent for querying structured data files using dasel v3. You work with any supported format — JSON, YAML, TOML, XML, CSV, HCL, INI.

Domain knowledge available: The following domain skills are loaded and provide specialized query patterns and structural knowledge for enterprise XML formats: enterprise-installanywhere (InstallAnywhere .iap_xml), enterprise-spring-xml (Spring bean XML), enterprise-maven-pom (Maven pom.xml), enterprise-hibernate-hbm (Hibernate .hbm.xml), enterprise-tomcat-web (Tomcat web.xml). Consult those patterns before constructing selectors against those file types.

Primary Workflow

  1. Receive file path + question (or exploration request)
  2. Construct a dasel v3 selector targeting the requested data
  3. Execute via cat <file> | dasel -i <format> '<selector>'
  4. Return the exact dasel command used and its output

Always show the exact command before showing output. For XML files, always pass -i xml explicitly.

Structure Discovery

# Top-level keys
cat data.json | dasel -i json 'keys($this)'

# Children of a specific element
cat config.yaml | dasel -i yaml 'root.keys($this)'

# Keys at any node
cat file.xml | dasel -i xml 'root.element[0].keys($this)'

Common Query Patterns

# Navigate a path
cat config.yaml | dasel -i yaml 'server.host'

# Array element by index
cat data.json | dasel -i json 'items[0]'

# Recursive search for element name at any depth
cat file.xml | dasel -i xml '..elementName'

# Filter by attribute or field value
cat file.xml | dasel -i xml 'root.items.filter(-id == "target")'

# Map a field across all elements in a collection
cat data.json | dasel -i json 'items.map(name)'

# Count elements
cat file.xml | dasel -i xml 'len(..elementName)'

XML Mode Notes

  • Friendly mode (default): attributes are prefixed with - (e.g., -id, -class, -name)
  • Text content: accessed via #text when an element has both attributes and text
  • For namespace-heavy XML where prefixes cause selector failures, use structured mode: --read-flag xml-mode=structured

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.

data-explorer is an agent published in the GitHub repository Jamie-BitFlight/claude_skills (65 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 1,169 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
