A skill your agent uses when the user wants to follow links across a domain and capture every reachable page as Markdown.

  • The user wants to follow links across a domain and capture every reachable page as Markdown
  • SKILL.md covers Quick recipe, Flag surface, When to pick which flags and Output, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Crawling A Site is an agent skill from hashgraph-online/awesome-codex-plugins. Use when the user wants to follow links across a domain and capture every reachable page as Markdown. Covers crawlberg crawl with depth, page caps, concurrency, rate limiting, domain scoping, robots, and output selection.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Rate limiting and Markdown. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Rate limiting
  • Tasks that involve Markdown

Example prompts

  • “/crawling-a-site”

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

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

  • Network

    No URLs in SKILL.md.

    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

Crawling A Site loads about 1.4k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 468 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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); files beside SKILL.md are not scanned.

Crawling a site

Reach for crawlberg crawl when one URL is not enough — the user wants the docs site, the blog, the marketing pages, or the whole domain.

Quick recipe

bash
crawlberg crawl https://example.com \
  --depth 3 \
  --max-pages 200 \
  --concurrent 8 \
  --rate-limit 250 \
  --stay-on-domain \
  --respect-robots-txt \
  --format markdown

Defaults you should usually override:

  • --depth 2 is shallow — set it explicitly.
  • --max-pages is unbounded by default; cap it for any unknown site.
  • --concurrent 10 is aggressive for small hosts; drop to 4-8 for third-party sites.

Flag surface

FlagDefaultPurpose
--depth, -d2Maximum hop count from the seed URL.
--max-pages, -n—Hard cap on pages fetched. Set this on any unknown site.
--concurrent, -c10Parallel in-flight requests.
--rate-limit200Milliseconds between requests to the same origin.
--stay-on-domainoffSkip links that leave the seed domain.
--respect-robots-txtoffHonour robots.txt. Pass it for any third-party host.
--proxy—HTTP, HTTPS, or SOCKS5 proxy URL.
--user-agent—Override the request UA. Be honest.
--timeout30000Per-request timeout in ms.
--browser-modeautoauto, always, never — see the headless-fallback skill.
--browser-endpoint—External CDP ws:// URL.
--formatjsonjson or markdown.
--config—Inline JSON or @file.json for the full CrawlConfig.

Multiple seed URLs are accepted positionally — the engine fans out with batch_crawl and aggregates results.

When to pick which flags

Docs sites you own
bash
crawlberg crawl https://docs.example.com \
  --depth 5 --max-pages 1000 --concurrent 16 --rate-limit 100 \
  --stay-on-domain --format markdown > docs.md

Higher concurrency and lower rate limits are fine on infrastructure you control.

Third-party sites
bash
crawlberg crawl https://blog.unknown.example \
  --depth 2 --max-pages 50 --concurrent 4 --rate-limit 500 \
  --stay-on-domain --respect-robots-txt --format markdown

Stay shallow, cap pages, throttle hard, obey robots.

Multi-seed batch
bash
crawlberg crawl \
  https://example.com/blog \
  https://example.com/docs \
  https://example.com/pricing \
  --depth 2 --max-pages 100 --stay-on-domain --format json

JSON output for batch is an array of { seed_url, result } entries — each result is a full crawl payload or { error: ... }.

Politeness checklist

  • Pass --respect-robots-txt on every third-party crawl.
  • Cap --max-pages — a runaway BFS can issue tens of thousands of requests.
  • Bump --rate-limit for hosts that show signs of stress (5xx, slowdowns).
  • Identify yourself via --user-agent crawlberg (contact@example.com).

Common pitfalls

  • No pages returned. The seed page may be JS-only — the engine falls back to headless automatically in --browser-mode auto, but never mode will silently produce an empty crawl. Re-run with --browser-mode always or check the headless-fallback skill.
  • Crawl leaves the domain. Pass --stay-on-domain. Combine with allow_subdomains: true in --config JSON to include subdomains.
  • Slow crawl. The default rate limit is 200 ms per origin — multiple seed URLs on the same host still share the bucket. Spread seeds across hosts or raise --concurrent for unrelated origins.
  • Memory growth. Each page carries full Markdown plus structured data. Stream JSON output to a file rather than holding it in memory; set --max-pages aggressively if downstream cannot keep up.

When to reach for map instead

If the user only needs the list of URLs (sitemap analysis, link planning, seeding another tool), use crawlberg map <url> — it skips rendering and returns a flat MapResult with hundreds of URLs in seconds.
