30 Claude Prompts That Write Changelogs

You are a release engineer who maintains changelogs to the Keep a Changelog 1.1 standard. <context> I need a complete CHANGELOG.md for my project, returned as one ready-to-commit Markdown file that follows keepachangelog.com and Semantic Versioning. </context> <inputs> - Project name: [PROJECT] - Current version and date: [E.G. 1.4.0, 2026-07-02] - What shipped in this release: [LIST OF CHANGES] - Notable past versions to seed history: [OPTIONAL PRIOR RELEASES] - Repo URL for compare links: [E.G. github.com/org/repo] </inputs> <task> Produce a full CHANGELOG.md: a header with the standard intro line, an [Unreleased] section, then the current release as [version] - date, sorting each change under the correct heading (Added, Changed, Deprecated, Removed, Fixed, Security). Bottom-anchor version compare links. Write each entry as a clear, past-tense, user-legible line. </task> <constraints> - Valid Markdown, exact Keep a Changelog section names and ordering, reverse-chronological versions. - No empty headings; omit categories with no entries. ISO dates. No marketing fluff. </constraints> <format> Return the complete CHANGELOG.md in a code block, then a short note on how to add the next release and keep the compare links correct. </format>

You are a maintainer adding a single release block to an existing Keep a Changelog file. <context> I already have a CHANGELOG.md. I need one new release entry that drops cleanly under [Unreleased], returned as a ready-to-paste Markdown block. </context> <inputs> - New version and date: [E.G. 2.1.0, 2026-07-02] - Raw list of what changed (any order): [PASTE CHANGES] - Anything user-visible vs internal: [OPTIONAL NOTES] - Any breaking changes: [YES/NO PLUS DETAIL] </inputs> <task> Write the release block as ## [version] - date, then bucket every change under the correct Keep a Changelog heading. Rewrite raw notes into crisp past-tense lines a reader understands. Flag breaking changes explicitly with a **BREAKING** prefix under Changed or Removed. </task> <constraints> - Only the standard six headings, only those that have entries, alphabetized headings per the spec order. - No duplicate entries, no internal jargon in user-facing lines, valid Markdown. </constraints> <format> Return the single release block in a code block, then note which items you judged breaking and why. </format>

You are a release manager curating the [Unreleased] section of a Keep a Changelog file. <context> Work has merged since the last tag but nothing is released yet. I need a well-organized [Unreleased] section, returned as a ready-to-commit Markdown block that I keep updating until cut day. </context> <inputs> - Merged work since last release: [PASTE PR TITLES OR NOTES] - Last released version: [E.G. 3.2.1] - Target next version (if known): [OPTIONAL] - Items still in progress to exclude: [OPTIONAL] </inputs> <task> Build the ## [Unreleased] block, sorting merged work into Added/Changed/Deprecated/Removed/Fixed/Security. Suggest the correct next SemVer bump (major/minor/patch) based on the contents and justify it in one line. </task> <constraints> - Exclude anything marked in-progress. Standard headings only, no empties. - Each line is user-legible and past tense; valid Markdown. </constraints> <format> Return the [Unreleased] block in a code block, then state the recommended next version and the one change that forced that bump. </format>

You are a release historian reconstructing a changelog from a project's version history. <context> My project has git tags but no CHANGELOG.md.

Where notes are thin, write conservative, accurate lines and mark uncertain sections rather than inventing detail. Add the compare-link footer across all versions. </task> <constraints> - Never fabricate features; if a tag has no info, use a single honest placeholder line. - Valid Markdown, exact heading names, ISO dates, correct compare links. </constraints> <format> Return the full CHANGELOG.md in a code block, then list which versions need a human to verify the sparse entries. </format>

You are an editor who normalizes chaotic changelogs into the Keep a Changelog standard. <context> My current changelog is inconsistent (mixed formats, wrong headings, marketing lines). I need it rewritten to strict Keep a Changelog format, returned as one ready-to-commit CHANGELOG.md. </context> <inputs> - Current changelog content: [PASTE EXISTING FILE] - Repo URL for compare links: [github.com/org/repo] - Anything to keep verbatim: [OPTIONAL] </inputs> <task> Rewrite the whole file: normalize version headers to [version] - ISO date, re-bucket every line under the six standard headings, split combined entries, strip marketing fluff, and preserve real information. Keep the same versions and dates; only fix structure and wording. Add a compare-link footer. </task> <constraints> - Do not drop factual content or invent new entries. Standard heading names and order only. - Consistent past-tense phrasing, valid Markdown, no empty sections. </constraints> <format> Return the reformatted CHANGELOG.md in a code block, then a short list of the structural problems you fixed. </format>

Lead with the most-requested feature. Translate every technical change into a user outcome. </task> <constraints> - No version numbers in the body copy (keep it human), no internal jargon, no filler. - Each highlight names a concrete thing the user can now do; scannable formatting. </constraints> <format> Return the release-notes copy as a formatted block, then a shorter 2-line variant for a toast or badge. </format>

TRY IT NOW, UPDATE THE APP] </inputs> <task> Write the email: 3 subject-line options, a preview text, a warm opener, one hero paragraph on the headline change and why it matters, a short "also new" bulleted list, a single clear CTA button label plus link placeholder, and a one-line sign-off. Keep it benefit-led and short enough to read on mobile. </task> <constraints> - One dominant CTA, no more than 4 secondary bullets, no jargon, plain text friendly. - Subject lines under 55 characters; specific, not clickbait. </constraints> <format> Return the subject options and full email body as a formatted block, then note the single metric this email should move. </format>

For a maintenance build, write a warm, honest "bug fixes and performance improvements" style note that still names one real fix. Keep it well under 4000 characters and scannable on a phone. </task> <constraints> - No version numbers or internal ticket IDs, no jargon; emoji only if the tone calls for it. - Lead with user value; concise bullets; nothing that would trip store review. </constraints> <format> Return the store notes as plain text ready to paste, then a shorter variant for the tighter Play Store early lines. </format>

You are a front-end developer building a self-hosted public changelog page. <context> I want a standalone changelog page I can host, built as one self-contained, responsive HTML file with inline CSS, previewable instantly as an artifact. </context> <inputs> - Product name and brand vibe: [PRODUCT, STYLE/COLORS] - Recent releases to render: [3-6 ENTRIES WITH DATE, VERSION, CHANGES] - Category labels and colors: [E.G.

Note which changes require consumer action before a date. </task> <constraints> - Endpoint and field names in backticks; explicit deprecation timelines; no vague wording. - Separate breaking from additive changes clearly; valid Markdown. </constraints> <format> Return the API changelog entry in a code block, then a one-line summary developers can paste into their upgrade ticket. </format>

You are a platform engineer writing deploy notes for an internal service release. <context> We are deploying a backend service and I need engineer-facing deploy notes for the release channel, returned as a ready-to-post Markdown block. </context> <inputs> - Service name and version/build: [SERVICE, VERSION] - Changes in this deploy: [PASTE LIST] - Config/env var changes: [OPTIONAL] - Migrations or feature flags: [OPTIONAL] - Rollback plan: [HOW TO REVERT] </inputs> <task> Write deploy notes: a summary line, What Changed (grouped by user-impacting vs internal), Config Changes (new/changed env vars with defaults), Migrations & Flags (order-sensitive steps), Monitoring (what metrics/alerts to watch post-deploy), and a Rollback section with exact steps.
