changeset

A release-note file for recording what changed and which version number should increase. A changeset is commonly used by projects that publish packages or other versioned software.

In plain words
What is it for?
Use it to inspect the current branch, choose a patch, minor, or major change, and create the required Markdown entry.
Why use it?
It keeps version bumps and changelog entries consistent instead of relying on memory when changes are released.

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

changeset 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 2d 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.

What it actually says

Create a changeset entry for the current branch's changes.

Instructions

  1. Run git diff main...HEAD --stat and git log main..HEAD --oneline to understand what changed on this branch.
  2. If no argument was provided, analyze the changes to determine:
    • Bump type: patch for fixes, minor for new features, major for breaking changes
    • Summary: A concise description of the change for the changelog
  3. If $ARGUMENTS was provided, parse it as [bump] [description] (e.g., minor Add changeset-based release workflow).
  4. Create a new markdown file in .changeset/ with a random lowercase-kebab-case name (e.g., .changeset/cool-birds-fly.md) using this exact format:
---
"@alchemy/mcp-server": <bump>
---

<description>

Where <bump> is patch, minor, or major and <description> is the changelog entry.

  1. Show the user the created changeset file and ask if they'd like to adjust anything.

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.

changeset is a skill published in the GitHub repository alchemyplatform/alchemy-mcp-server (88 stars, last pushed 22d ago), licensed MIT. It adds 20 tokens to every session and 296 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
