Web Archive Scraper

What it does

When your agent uses it

• Tasks that involve Web scraping

Example prompts

• “/web-archive-scraper”

Requirements

• Python 3

Workflow steps

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

1. 1CDX API search — Queries web.archive.org/cdx/search/cdx for snapshots matching the URL
2. 2Filtering — Filters by date range, HTTP status code, and MIME type
3. 3Dedup — Collapses to one snapshot per day by default to avoid redundant results
4. 4Content fetch — Optionally fetches the raw archived HTML (using id_ modifier to skip Wayback toolbar)
5. 5Text extraction — Strips HTML tags for readable text output when fetching content

What it can do on your machine

Read from SKILL.md and the folder at commit c650c6d. 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:

  • python3

  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:

  • botkeeper.com
  • web.archive.org

  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

Web Archive Scraper loads about 901 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 270 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~62

When it runs · the whole SKILL.md, loaded when a task matches

~901

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

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.
