Ran the bundled process.py live on a 7-row sales CSV: dedupe, group-by aggregation and describe_data all returned correct numbers. But an ad-hoc stdlib script I wrote with no skill produced byte-identical totals, means and counts, so it saves a bit of typing without beating the baseline. Clean, well-documented convenience helpers with no measurable edge over an agent writing the same code inline.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 5/10
- Docs & honesty 5/5
What File Processing does
Processes structured data files (CSV, JSON, delimited text) with cleaning, filtering, grouping, aggregation, descriptive stats and format conversion. Triggers when a user asks to analyze, dedupe, summarize or convert a data file. Ships a single process.py of pure-stdlib helper functions.
How to install File Processing
git clone https://github.com/aws-samples/sample-strands-agents-agentskills
mkdir -p ~/.claude/skills
cd sample-strands-agents-agentskills && cp -r skills/file-processing ~/.claude/skills/file-processing
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
Commands — how to trigger File Processing
-
/file-processingLoad, clean, aggregate and convert CSV/JSON files via stdlib Python helpers
It also activates on plain-language prompts like these:
-
Dedupe this sales CSV and give me group-by totals per category. -
Clean this messy JSON export and convert it to a proper CSV file. -
Compute descriptive stats on this dataset's numeric columns for me.
Frequently asked questions
- Is the File Processing skill free?
- Yes. The skill itself is free from aws-samples/sample-strands-agents-agentskills. SkillProof publishes the install command and an independent test verdict at no cost.
- Does File Processing work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 17, 2026. Verdict: Works with setup. Ran the bundled process.py live on a 7-row sales CSV: dedupe, group-by aggregation and describe_data all returned correct numbers. But an ad-hoc stdlib script I wrote with no skill produced byte-identical totals, means and counts, so it saves a bit of typing without beating the baseline. Clean, well-documented convenience helpers with no measurable edge over an agent writing the same code inline.
- What is the File Processing SkillProof Score?
- 8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.
- How do I install File Processing?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use File Processing with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
