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

research-folder-synthesizer 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 11d 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 — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Research Folder Synthesizer

This skill synthesizes a folder of heterogeneous local files (markdown notes, plain-text articles, research excerpts) into a structured thematic report. It clusters ideas across files, surfaces key findings and contradictions, and produces a single research-synthesis.md ready to use as a foundation for reports, PRDs, or strategy documents.

Input:

  • A folder path or list of local file paths (.md, .txt, plain text)
  • Optional: a focus question or research angle to guide thematic clustering

Output:

  • research-synthesis.md — structured markdown with executive summary, named themes, key findings, contradictions/gaps, and source index

Language Detection

Detect the user's language from their message:

  • If Russian (or contains Cyrillic): respond in Russian
  • If English (or other Latin-script language): respond in English
  • If ambiguous: respond in the language of the trigger phrase used

Instructions

Step 1: Validate Input

  1. Check that the user has provided a folder path or a list of files.

    • If nothing provided: stop and report — "No files found. Provide a folder path or paste file contents directly."
  2. Attempt to read all files at the provided path.

    • Log each file name and detected type (.md, .txt, or plain text) in the report preamble.
    • Skip unreadable files (binary, images, etc.); add them to a "Skipped files" list — do not stop the pipeline.
    • If all files are unreadable: stop and report — "No readable text found. Provide .md, .txt, or plain-text files."
  3. If only one file is provided: note that cross-source comparison will be unavailable; proceed with single-source synthesis.

  4. If >20 files: note that depth per file will be reduced for brevity; proceed.

Negative Cases:

  • Folder path not provided or folder empty → stop with clear message (Step 1.1).
  • All files unreadable → stop with clear message (Step 1.2).
  • User provides a URL instead of local files → clarify: "This skill works with local files. Paste the text directly or save it as a .txt file first."

Changes

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.
