api-changelog-versioningCreates comprehensive API changelogs documenting breaking changes, deprecations, and migration strategies for API consumers.
API Changelog Versioning is an agent skill from secondsky/claude-skills. Creates comprehensive API changelogs documenting breaking changes, deprecations, and migration strategies for API consumers. Use when managing API versions, communicating breaking changes, or creating upgrade guides.
Its SKILL.md is about 500 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 Development, covering Changelog and release notes and Code migrations. The repository describes itself as: Production-ready skills for Claude Code CLI - Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 8837836. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and json).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
API Changelog Versioning loads about 497 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 74 words of instructions outside code blocks.
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.
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.

Creates comprehensive API changelogs documenting breaking changes, deprecations, and migration strategies for API consumers.
API Changelog Versioning fits situations like: managing API versions; communicating breaking changes; creating upgrade guides.
Run `npx skills add secondsky/claude-skills --skill api-changelog-versioning -a claude-code`. Or copy the skill folder (plugins/api-changelog-versioning/skills/api-changelog-versioning in secondsky/claude-skills) into .claude/skills/api-changelog-versioning in your project. Claude Code loads it when a task matches its description.
Run `npx skills add secondsky/claude-skills --skill api-changelog-versioning -a codex`. Or copy the skill folder (plugins/api-changelog-versioning/skills/api-changelog-versioning in secondsky/claude-skills) into .agents/skills/api-changelog-versioning in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add secondsky/claude-skills --skill api-changelog-versioning -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/api-changelog-versioning, .gemini/skills/api-changelog-versioning, .github/skills/api-changelog-versioning and .opencode/skills/api-changelog-versioning in your project.
SKILL.md names no scripts, command-line tools or credentials: API Changelog Versioning is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
API Changelog Versioning is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 497 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
