finding-changelogs

finding-changelogs is a skill for Claude Code, Codex from buildinternet/releases. It costs 39 tokens per session (4,125 once invoked), scanned A, original, Apache-2.0.

A method for finding the most reliable source of a product’s changelog, such as an RSS feed, GitHub Releases, a Markdown file, or an API. A changelog is a record of product updates and release notes.

In plain words
What is it for?
Use it when given a changelog URL or release-notes page and you need to choose how to collect its entries. It covers feed discovery, provider detection, GitHub, Markdown, and scraping fallback.
Why use it?
It can avoid fragile page scraping by finding structured sources that are easier to read. It also checks that a discovered feed contains real release updates rather than blog posts or unrelated articles.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

finding-changelogs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Finding Changelogs

Determine the best way to get structured release data from a changelog or release notes page.

Many pages have better-structured data sources behind them — RSS feeds, raw markdown files, or API endpoints. Finding those avoids the complexity of parsing rendered HTML.

Content Verification

After discovering a feed or structured source, always spot-check the entries before accepting it. Sample a few entries and verify they are actual changelog or release content — not blog posts, marketing articles, tutorials, or unrelated editorial content.

Red flags that a feed is wrong:

  • Entry URLs point to /blog/ paths rather than /changelog/ or /releases/ paths
  • Titles read like articles or tutorials (e.g., "Choosing a logging library: The definitive guide")
  • No version numbers, semver patterns, or feature/fix language anywhere in the entries
  • The feed URL is site-wide (e.g., /feed.xml) rather than section-specific (e.g., /changelog/feed.xml)
  • Entry content discusses opinions, comparisons, or industry trends rather than product changes

If the entries don't look like releases, the feed is likely the wrong one. Look for a more specific feed, or fall back to a different ingestion method.

Watch for redirects. A URL like blog.example.com/changelog/ may redirect to example.com/changelog/, but feed discovery may have already found the blog's site-wide feed before the redirect. Always check whether the discovered feed is scoped to the changelog section, not the entire site.

Priority Order

Well-known files > Link relations > Feeds > GitHub Releases API > raw markdown > page scraping.

For github sources, the fetch pipeline ingests tagged releases and the repo's canonical CHANGELOG.md (or CHANGES.md / HISTORY.md / RELEASES.md / NEWS.md at the repo root) on every fetch pass — the file is surfaced in the web UI as a separate tab, embedded on demand by the get_catalog_entry MCP tool, and is often the richer source when a project ships entries that never became tagged releases. The refresh piggybacks on each GitHub fetch with a content-hash short-circuit, so stored files stay in sync with tagged releases. You don't need to add a second source for the CHANGELOG file; the github adapter handles both.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
