Description
Summarize URLs, local files (PDFs, images, audio), and YouTube links using the summarize CLI with customizable length and model options.
README (SKILL.md)
name: summarize name: summarize description: Summarize URLs or files with the summarize CLI (web, PDFs, images, audio, YouTube). homepage: https://summarize.sh metadata: {"clawdbot":{"emoji":"🧾","requires":{"bins":["summarize"],"env":["SKILLBOSS_API_KEY"]},"install":[{"id":"brew","kind":"brew","formula":"steipete/tap/summarize","bins":["summarize"],"label":"Install summarize (brew)"}]}}
Summarize
Fast CLI to summarize URLs, local files, and YouTube links.
Quick start
summarize "https://example.com" --model google/gemini-3-flash-preview
summarize "/path/to/file.pdf" --model google/gemini-3-flash-preview
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto
Model + keys
Set the API key for SkillBoss API Hub:
SKILLBOSS_API_KEY— unified key for all providers, routes viahttps://api.skillbossai.com/v1/pilot
SkillBoss API Hub supports all major LLM providers (OpenAI GPT, Anthropic Claude, Google Gemini, xAI Grok, etc.) and automatically selects the best model. No provider-specific keys needed.
Default model is google/gemini-3-flash-preview if none is set.
Useful flags
--length short|medium|long|xl|xxl|\x3Cchars>--max-output-tokens \x3Ccount>--extract-only(URLs only)--json(machine readable)--firecrawl auto|off|always(fallback extraction via SkillBoss API Hub scraping, usesSKILLBOSS_API_KEY)--youtube auto(YouTube fallback via SkillBoss API Hub, usesSKILLBOSS_API_KEY)
Config
Optional config file: ~/.summarize/config.json
{ "model": "openai/gpt-5.2" }
Optional services (all routed via SkillBoss API Hub with SKILLBOSS_API_KEY):
- Web scraping for blocked sites (
type: "scraper"via/v1/pilot, replacesFIRECRAWL_API_KEY) - YouTube transcript fallback (
type: "scraper"via/v1/pilot, replacesAPIFY_API_TOKEN)
Usage Guidance
Before installing: 1) Ask the publisher to clarify why the registry metadata lists no required binaries/env but SKILL.md requires the 'summarize' binary and SKILLBOSS_API_KEY. 2) Confirm whether local files (PDFs, images, audio) are processed locally or uploaded to api.skillbossai.com when using the CLI or any fallback flags (firecrawl, --youtube fallback). 3) If you must use SKILLBOSS_API_KEY, treat it as sensitive: avoid using it with private/confidential files and consider a limited-scope or disposable key. 4) Verify the Homebrew tap (steipete/tap) and the summarize binary's authenticity before installing from it. 5) If you need strong privacy guarantees, avoid enabling fallback scraping that routes data to third-party hubs or request an alternative that runs entirely locally.
Capability Analysis
Type: OpenClaw Skill
Name: kirk-summarize
Version: 1.0.0
The skill directs all summarization traffic (URLs, local files, and YouTube transcripts) through a third-party proxy service ('SkillBoss API Hub' at api.skillbossai.com), which poses a significant data privacy and exfiltration risk. The documentation in SKILL.md references non-existent AI models such as 'openai/gpt-5.2' and 'google/gemini-3-flash-preview', which is highly deceptive. While the tool provides a functional CLI via a Homebrew tap, the requirement for a unified 'SKILLBOSS_API_KEY' to route all data through an unverified intermediary is a major red flag.
Capability Tags
Capability Assessment
Purpose & Capability
The skill claims to summarize URLs, files, and YouTube links using a 'summarize' CLI which aligns with the description. However, the SKILL.md frontmatter declares required items (binary 'summarize' and env SKILLBOSS_API_KEY and a brew install formula) while the registry metadata presented to the evaluator lists no required binaries or env vars. That registry ↔ SKILL.md inconsistency is unexplained and reduces trust.
Instruction Scope
Runtime instructions direct use of the summarize CLI and explicitly describe fallback behaviors that use SkillBoss API Hub (web scraping, YouTube transcript fallback, 'firecrawl', etc.). Those fallbacks will route content (URLs and possibly scraped page contents) to an external service (api.skillbossai.com). The docs do not clearly state whether local files (PDFs, images, audio) are processed locally or uploaded to that external hub when fallbacks are used. Uploading sensitive local files or scraped pages to a third party could be undesired data exfiltration.
Install Mechanism
There is no install spec in the registry (skill is instruction-only), but the SKILL.md metadata suggests installing via a Homebrew formula from 'steipete/tap/summarize'. That is a third-party tap rather than an official vetted package source; it's plausible but not verified. The mismatch between registry install metadata (none) and SKILL.md (brew formula) is concerning because the marketplace record doesn't advertise what would actually be installed if followed.
Credentials
SKILL.md references and effectively requires SKILLBOSS_API_KEY (a unified key that routes to multiple LLM providers) for scraping/fallback features and suggests routing a variety of operations through SkillBoss. The registry metadata provided to the evaluator did not declare this required env var. Requesting a single broad key that can access multiple provider backends is proportionate only if the user explicitly intends to route data through that hub. Without that context, the requirement is too broad and potentially exposes many providers and data to a third party.
Persistence & Privilege
The skill is not always-enabled and does not request persistent elevated privileges. It references an optional per-user config file (~/.summarize/config.json), which is normal for a CLI. There is no evidence the skill modifies other skills or global agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install kirk-summarize - After installation, invoke the skill by name or use
/kirk-summarize - Provide required inputs per the skill's parameter spec and get structured output
