Description
Research any topic's trends across Reddit, Hacker News, X, YouTube, and GitHub to generate multi-platform, actionable trend reports in minutes.
Usage Guidance
This skill looks like a straightforward aggregator, but check these before installing: 1) Confirm which platforms you need — SKILL.md and README disagree (X/Twitter and Product Hunt are mentioned but not documented in the runtime instructions). 2) Ask the publisher for a source or homepage so you can verify provenance. 3) Understand that the skill uses generic web_fetch and may make many external requests (scraping public pages) — monitor network activity and avoid running it with sensitive context. 4) If you expect robust GitHub/YouTube/X data, plan to provide appropriate API tokens (and only if you trust the skill/author). 5) Prefer installing only after a short test run with innocuous queries and watch for unexpected endpoints or excessive requests.
Capability Analysis
Type: OpenClaw Skill
Name: xiaobai-trend-harvester
Version: 2.0.0
The 'trend-harvester' skill is a research tool designed to aggregate public data from platforms like Hacker News, Reddit, and GitHub. The instructions in SKILL.md and README.md are well-documented, align with the stated purpose, and even include security-positive directives such as treating fetched content as untrusted ('Prompt Guard'). No malicious code, data exfiltration patterns, or harmful prompt injections were identified.
Capability Assessment
Purpose & Capability
The declared purpose (aggregate trends from multiple platforms) matches the SKILL.md's behavior (HN via hn.algolia.com, Reddit/GitHub/YouTube via web_fetch/GitHub API). However the top-level description and README mention additional platforms (X/Twitter and Product Hunt) that are not listed in the SKILL.md platforms table — that's an internal inconsistency. Also the skill has no listed source/homepage or owner context, which reduces traceability.
Instruction Scope
SKILL.md instructs the agent to call hn.algolia.com and use generic 'web_fetch' searches and the GitHub API. It does not instruct reading local files or environment variables. The use of generic 'web_fetch' is open-ended: the agent may retrieve arbitrary URLs to assemble results (expected for a scraper), but the instructions don't limit which endpoints to query, how to respect robots/rate limits, or how to avoid private content.
Install Mechanism
Instruction-only skill with no install spec and no code files — nothing is written to disk by an installer. This is the lowest-risk install model.
Credentials
The skill declares no required env vars or credentials. That's coherent for limited, unauthenticated scraping, but in practice GitHub, YouTube, and X APIs may require tokens for reasonable rate limits or to access full data. The absence of required credentials limits functionality but isn't itself malicious; it does mean the agent may resort to public scraping instead of authenticated API queries.
Persistence & Privilege
always is false and there is no install-time persistence or claims to modify other skills or system configuration. The skill does not request elevated/system privileges.
