Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.01637 |
| Opus 5 | $0.00052 | $0.00818 |
| Sonnet 5 | $0.00021 | $0.00327 |
| Haiku 4.5 | $0.00010 | $0.00164 |
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
-
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."
-
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."
- Log each file name and detected type (
-
If only one file is provided: note that cross-source comparison will be unavailable; proceed with single-source synthesis.
-
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
.txtfile first."
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

research-folder-synthesizer is a skill published in the GitHub repository KirKruglov/claude-skills-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 104 tokens to every session and 1,637 once invoked, about $0.0005 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 2026-08-30.
Other skills, from other repositories
spark-video-director
Translate a screenplay (one scene at a time) into a provider-agnostic storyboard fragment for the spark-video pipeline. Wraps Shanyin Super Director Master when available — the upstream Shanyin SKILL is the single source of truth for craft when present.
spark-video-episode
One-shot autopilot orchestrator — runs the full spark-video pipeline (screenwriter ↔ director per-scene parallel → render chain-DAG parallel + per-clip review → stitch). User confirms at 4 gates (+ 1 mode gate at start + 1 BGM gate when bgm/ folder detected). Use when the user wants "make me an episode" in one command.
vox-video-director
Turn ONE topic into a finished Vox-style paper-collage explainer / ad video, end to end with Aliyun Bailian CLI + local ffmpeg — script, collage keyframes, motion, voice-over, music, captions, all automated. Use this whenever the user wants a "Vox style" video, a paper/torn-paper collage animation, a "motion collage"…
bailian-train-deploy
A workflow for using Alibaba Cloud’s Bailian command-line tool to fine-tune or directly deploy AI models as callable services. It covers text, speech-synthesis, image-generation, and video-generation models.
spark-video-cast
Scaffold and generate reference assets for characters (cast), locations (movie-set / set dressing), and key props — the three pillars of visual consistency in spark-video. Wraps bl image generate / edit for portrait creation. Use when adding new characters/locations/props or when costume/state changes are needed.
spark-video-screenwriter
Turn a user's premise into a structured screenplay (one scene at a time) for the spark-video pipeline. Wraps Shanyin Super Screenwriting Master when available — that upstream Shanyin SKILL is the single source of truth for craft when present.
