What it does

URL Analysis is an agent skill from aiskillstore/marketplace. URL validation and contextual analysis specialist. Use when validating links, analyzing URL context, extracting links from content, or ensuring link appropriateness. Combines technical validation with content analysis.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/validate-urls.py` and `skill-report.json`).

The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Validating links
  • Analyzing URL context
  • Extracting links from content
  • Ensuring link appropriateness

Example prompts

  • “/url-analysis”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Technical Validation: Checks HTTP status, redirects, SSL
  2. Contextual Analysis: Evaluates link appropriateness
  3. Link Extraction: Extracts and categorizes links
  4. Content Relevance: Checks if linked content matches context
  5. Security Analysis: Identifies security concerns
  6. Quality Assessment: Provides link quality scores

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • old-site.com
    • new-site.com
    • broken-link.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

URL Analysis loads about 1k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
