file-intel

file-intel is a skill for Claude Code, Codex from julianobarbosa/claude-code-skills. It costs 76 tokens per session (803 once invoked), scanned A, original, MIT.

A file-processing workflow that sends files to a Gemini-based script and creates summaries for an Obsidian knowledge vault. Obsidian is a note-taking application that stores linked Markdown notes.

In plain words
What is it for?
Use it to process PDFs, presentations, spreadsheets, word-processing files, CSVs, JSON, and text files, then review the generated summaries and master digest.
Why use it?
It turns mixed document collections into organized summaries instead of requiring each file to be read manually.

Written for no agent in particular: nothing here depends on one. Also seen: names the AskUserQuestion tool; mentions Claude Code.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/process_files_with_gemini.py <folder_path>.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

file-intel 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 8d 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.

File Intel — Gemini File Processor

Runs scripts/process_files_with_gemini.py on a folder of files and produces Obsidian-ready summaries.

Step 1: Get the folder

Use AskUserQuestion:

Question: "Which folder should I process?"
Options:
1. "This vault's inbox/" — process the inbox folder
2. "Custom path" — user specifies a folder

If the user selects option 2, they'll type the path in the "Other" input.

Step 2: Run the script

Run via Bash from the vault root:

python scripts/process_files_with_gemini.py <folder_path>
  • If inbox/: python scripts/process_files_with_gemini.py inbox/
  • If custom path: pass it as the argument

Show the terminal output as it runs so the user can see files being processed live.

Step 3: Open the output

After the script completes, open the output folder:

open "outputs/file_summaries/YYYY-MM-DD/"

Replace YYYY-MM-DD with today's date from the script output.

Step 4: Report back

Tell the user:

  • How many files were processed
  • Where the summaries landed
  • Point them to MASTER_SUMMARY.md as the single-file digest of everything
  • Suggest: "Open Claude Code and say: Sort everything in inbox/ into the right folders"

Notes

  • Supported formats: PDF, PPTX, XLSX, DOCX, CSV, JSON, XML, MD, TXT, PY, JS, HTML, CSS
  • Output: outputs/file_summaries/YYYY-MM-DD/
  • Each file gets its own *_summary.md
  • MASTER_SUMMARY.md combines all summaries into one digest
  • Summaries are context-aware: deliverables (invoices, reports) vs reference files (code, config) get different formats

Gotchas

  • Encoding detection is best-effort, not deterministic: Files saved as Windows-1252 or Latin-1 may be processed as garbled UTF-8 instead of failing loudly. Spot-check the first summary of any batch from unknown sources — if accented characters render as mojibake, the source encoding was misdetected.
  • Password-protected and encrypted PDFs return blank summaries: Gemini cannot extract text from locked PDFs but the script does not flag them as failures. Check the file size of each *_summary.md — anything under ~200 bytes is suspect.
  • Scanned-image PDFs depend on OCR confidence: Low-DPI scans, handwriting, or rotated pages produce summaries with hallucinated content rather than honest "could not read." Verify scanned documents against the original before trusting downstream decisions.
  • XLSX files with multiple sheets summarize only the active sheet: The processor reads what the workbook opens to by default; other sheets are skipped silently. For multi-sheet financials, split into separate files or expect partial coverage.
  • MASTER_SUMMARY.md grows linearly and exceeds context on large folders: A 200-file inbox produces a digest too large to feed back into another LLM call without truncation. For batches over ~50 files, work from the per-file summaries instead of the master.
  • Re-running on the same folder writes to a new YYYY-MM-DD/ subdirectory: Two runs on the same day overwrite each other; runs on different days produce duplicates without cross-reference. Clear or archive prior output before re-processing.

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.
