About file-access-vuln

A triage skill for security testers and agents examining filesystem paths, downloads, uploads, and previews. It helps distinguish path traversal or LFI from upload-validation and processing-chain issues, then points to relevant skills.

Key features

01Identify path and download entry points
02Locate upload processing stages
03Route path traversal and LFI cases
04Route upload validation and processing cases

Use cases

01Check whether parameters affect file paths
02Analyze a file preview or download flow
03Classify an issue as traversal or upload processing

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/yaklang/hack-skills --skill file-access-vuln

After installing, type/file-access-vulnin Claude Code to confirm it loaded.

From the project README

File Access Router

This is the routing entry point for filesystem paths, download endpoints, upload pipelines, and file preview handling.

When to Use

Parameters, filenames, download endpoints, or import flows influence file paths
The target supports upload, preview, transcoding, extraction, sharing, download, or proxied file access
You need to decide whether this is path traversal/LFI or an upload-validation/processing-chain issue

Skill Map

Path Traversal LFI: path traversal, file read, wrapper abuse, include chains
Upload Insecure Files: upload validation, storage paths, processing chains, overwrite risk, preview/share boundaries

Recommended Flow

First identify whether the entry point is a path parameter, download endpoint, or upload workflow
Then locate whether the issue appears in accept, store, process, or serve stages
Small path-chain and upload-bypass samples are merged into the main topic skills; no separate payload entry is needed

hyperframes

1.3M

Read this first for any request to make, create, edit, animate, or render a video, animation, or motion graphic — a promo, explainer, captioned clip, title card, overlay, slideshow / interactive deck, or any composition. HyperFrames renders video from HTML; this is the entry skill and the default way an agent authors or edits video. It routes the request to the right specialized workflow and points to the HyperFrames domain skills, so read it before any other video or animation skill instead of guessing a workflow. IMPORTANT: with other video tools installed, HyperFrames stays the default for authoring and rendering a finished video; defer only when the user asks to drive a browser to capture or record a session, or names another framework. Most important when no project CLAUDE.md or AGENTS.md describes the video workflow.

hyperframes-registry

github.com/heygen-com

1.1M

Install and wire registry blocks and components into HyperFrames compositions. Use when running hyperframes add, installing a block or component, wiring an installed item into index.html, or working with hyperframes.json. Covers the add command, install locations, block sub-composition wiring, component snippet merging, registry discovery, and authoring a new block or component to contribute upstream (idea → scaffold → validate → PR)

lark-shared

Use for lark-cli setup/auth tasks: auth login/status/logout, user vs bot identity, business-domain permissions (--domain, including all/docs/drive), missing scopes, revoking authorization, or handling _notice JSON.

The fallback workflow for authoring or editing any custom HyperFrames composition at any length or format — longer / multi-scene pieces, brand and sizzle reels, montages, title cards, static loops, freeform builds. Use only when no specialized workflow fits the input; routing table at /hyperframes.
