What it does

Check Links is an agent skill from wagtail/awesome-wagtail. Guides the automated archival workflow of awesome links. Fetching links data, moving stale entries.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/check_links.py`).

It works with GitHub. The repository describes itself as: A curated list of awesome packages, articles, and other cool resources from the Wagtail community. The licence is CC0-1.0.

Example prompts

  • “Use the check-links skill to guide the automated archival workflow of awesome links. An agent skill from wagtail/awesome-wagtail”
  • “/check-links”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Run the link checker
  2. Read the report
  3. Create or update the archive file
  4. Commit changes

What it can do on your machine

Read from SKILL.md and the folder at commit 70a72b5. 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:

    • git
    • gh

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

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.astral.sh

    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

Check Links loads about 898 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 417 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~898

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.

Overview

Analyze and maintain links in the README. Fetches metadata for each link, detects stale entries, auto-updates GitHub repo titles and descriptions, and produces a structured report for archival decisions.

Requirements

  • Python 3.12+ with uv
  • gh CLI authenticated (gh auth status)
  • Network access for HTTP requests (httpx)

Available scripts

  • scripts/check_links.py — Fetches metadata for all links in README.md and generates a Markdown report on stdout.

Workflow

bash
./scripts/check_links.py --dry-run

Always run with --dry-run first to preview changes without modifying the README. Re-run without --dry-run to auto-update GitHub repo titles and descriptions when you're ready.

Add --verbose to see progress and API call details on stderr.

The database is stored at .awesome-wagtail.duckdb by default. Subsequent runs reuse cached data (24 h for GitHub, 30 d for web pages).

2. Read the report

The report printed to stdout is your action plan. It contains these sections:

Auto-Archive Candidates (GitHub)

Repos that are archived on GitHub or have not been pushed to in over 24 months. These should be moved to docs/archive.md and removed from README.md.

Needs Review — 12–24 months (GitHub)

Repos with no commits in 12–24 months. For each entry, check whether the repo's GitHub page or its entry in README.md mentions "archived", "deprecated", or "unmaintained". If so, move to archive. If the repo is still active despite infrequent commits, leave it in place.

Repo link titles that differ from the project name found in the repo's README heading. Review the list — many README headings contain badge markup or instructions rather than a clean project name. Only update titles that are clearly better.

Show full SKILL.md (151 more words)Show less

Repo descriptions that differ from GitHub's project description. In most cases the GitHub description is shorter and more accurate. Apply these updates to README.md.

Auto-Archive Candidates (web pages)

Pages that have not been updated in over 5 years (based on HTTP Last-Modified headers, <meta> tags, or schema.org data). Move these to docs/archive.md.

Title Mismatches (web pages)

Page titles in README.md that differ from the actual <h1> or <title> of the page. Review and update if the fetched title is a better description of the link.

3. Create or update the archive file

The archive lives at docs/archive.md. Mirror the same section structure as README.md (section > subsection). For each archived link:

  1. Remove the line from README.md
  2. Add the line under the matching section in docs/archive.md

If the archive file does not exist yet, create it with:

markdown
# Awesome Wagtail Archive

> Archived projects from the main README that are no longer actively maintained.

## Apps

### Blogging/news

... archived items moved here ...
4. Commit changes

When finished, review the diff and commit:

bash
git diff
git add -A
git commit -m "check-links: archive stale entries and update metadata" --trailer "Assisted-by: <Agent harness> (<Model name>)"
