description: "Write and maintain release-history artifacts for shipped changes: `CHANGELOG.md` updates, release notes, migration/deprecation updates, and lightweight game patch notes. Use when the main job is turning shipped evidence into the smallest truthful release-writing packet for developers, customers, internal stakeholders, or players. Also owns the retired `release-notes` name: turn tickets, PRDs, or Git logs into user-facing notes that lead with the benefit. Triggers on: changelog, release notes, patch notes, migration update, deprecation notice, version notes, what shipped, what changed, what's new, announce product updates. Route internal specs/runbooks to `technical-writing`, API portals to `api-documentation`, end-user tutorials to `technical-writing`, rollout execution to `deployment-automation`, and launch messaging to `marketing-automation`."

# Changelog Maintenance

Use this skill when the deliverable is **release history or shipped-change communication**, not a broad documentation or launch-campaign bundle.

`changelog-maintenance` is the documentation-cluster anchor for:
- `CHANGELOG.md` upkeep
- GitHub / GitLab / docs-site release notes
- migration and deprecation updates tied to a shipped change
- customer-facing “what changed” summaries
- lightweight game patch notes and small update posts

Read these support docs before choosing the mode or boundary:
- [references/modes-and-boundaries.md](references/modes-and-boundaries.md)
- [references/output-packets-and-channel-handoffs.md](references/output-packets-and-channel-handoffs.md)
- [references/release-note-quality-checklist.md](references/release-note-quality-checklist.md)
- [references/automation-and-source-of-truth.md](references/automation-and-source-of-truth.md)

## When to use this skill
- A repo needs a durable changelog entry or `Unreleased` refresh based on shipped work
- A release needs audience-appropriate notes for developers, customers, internal stakeholders, or players
- A breaking change, deprecation, or compatibility shift needs a migration update linked from release history
- Release automation drafted notes, but the output still needs truthful grouping, clearer wording, or better route-outs
- A game update needs concise patch notes without collapsing into marketing copy, deployment runbooks, or full help docs
- The real job is deciding the smallest release-writing packet rather than writing every neighboring document from scratch

## When not to use this skill
- **The main job is an internal spec, runbook, ADR, rollout plan, or deep migration procedure** → `technical-writing`
- **The main job is published API / SDK / webhook / developer-portal content** → `api-documentation`
- **The main job is end-user onboarding, tutorials, screenshots, FAQs, or help-center walkthroughs** → `technical-writing`
- **The main job is deployment execution, environment promotion, rollback mechanics, or release orchestration** → `deployment-automation`
- **The main job is launch copy, feature positioning, campaign sequencing, or GTM messaging** → `marketing-automation`
- **There is no credible shipped evidence yet** → collect proof first instead of inventing release notes from a roadmap or TODO list

## Instructions

### Step 1: Classify one primary release-writing mode
Normalize the request before drafting.

```yaml
changelog_mode:
  primary_mode: changelog | release-notes | migration-update | game-patch-notes
  audience: developers | end-users | mixed | players | internal-stakeholders | unknown
  release_scope: patch | minor | major | rolling | unknown
  source_of_truth: release-pr | tagged-release | prs | issues | commits | docs | mixed | unknown
  publishing_surface: changelog-file | github-release | docs-site | in-app-updates | steam-news | mixed | unknown
  automation_context: manual | release-drafter | changesets | release-please | autogenerated-release-notes | mixed | unknown
  output_shape: single-entry | summary-plus-links | migration-brief | patch-note-brief | sync-packet | unknown
```

Use one mode per run:
- `changelog` → durable repo history in `CHANGELOG.md`
- `release-notes` → audience-facing summary of what changed and why it matters
- `migration-update` → changed behavior, required actions, deadlines, and compatibility notes
- `game-patch-notes` → concise player-facing update summary

### Step 2: Confirm audience, proof, and route-outs
Answer these before writing:
1. Who reads this first?
2. What action should they take after reading it?
3. Which shipped evidence proves each headline claim?
4. Which deeper artifact should carry the rest?

Quick route-out table:

| If the request sounds like... | Use |
|---|---|
| “Write the architecture / rollout / runbook / internal migration plan” | `technical-writing` |
| “Publish API reference, SDK docs, auth troubleshooting, or portal pages” | `api-documentation` |
| “Write help docs, tutorials, screenshots, or FAQs for the changed workflow” | `technical-writing` |
| “Plan deploy / rollback / release execution” | `deployment-automation` |
| “Write launch copy / announcement / campaign messaging” | `marketing-automation` |
| “Summarize shipped changes truthfully for a release surface” | `changelog-maintenance` |

### Step 3: Gather the smallest truthful evidence set
Do not write release history from memory alone. Pull the smallest credible packet first:
- merged release PR, tag, or release entry if it exists
- merged PRs / issues / commits included in the release
- linked migration docs, upgrade notes, or help docs
- breaking changes, removals, deprecations, deadlines, or rollout caveats
- publishing-surface constraints (`CHANGELOG.md`, GitHub Release, customer update hub, Steam patch-note post)
- automation context, if any

If evidence is incomplete, label assumptions and missing proof explicitly.

### Step 4: Choose the smallest useful artifact packet
Use [references/output-packets-and-channel-handoffs.md](references/output-packets-and-channel-handoffs.md).

Default shapes:
- `single-entry` → one changelog entry or one release-note block
- `summary-plus-links` → short release summary plus migration/help/API links
- `migration-brief` → what changed, who is affected, required action, deadline, link-outs
- `patch-note-brief` → concise new content / tuning / fixes / known issues packet
- `sync-packet` → release-note draft plus list of downstream docs or channels that must stay aligned

Do not ship a broad handbook when one release packet and a short sync list will do.

### Step 5: Apply mode-specific writing rules
- **Changelog**: favor grouped notable changes over commit archaeology; keep compare links or version/date framing when the repo uses them.
- **Release notes**: lead with impact, not internal ticket numbers; keep wording plain and scannable.
- **Migration update**: foreground required action, affected readers, deadline, and compatibility risk.
- **Game patch notes**: keep the note lightweight and player-facing; do not smuggle rollout mechanics or campaign copy into it.

### Step 6: Keep record, communication, and promotion separate
Guard these boundaries aggressively:
- changelog / release notes summarize what shipped
- migration detail lives in linked migration docs when the procedure is too large for the summary
- tutorials / FAQs live in `technical-writing`
- API and integration detail lives in `api-documentation`
- rollout / rollback mechanics live in `deployment-automation`
- campaign-style language lives in `marketing-automation`

### Step 7: Work with automation without surrendering judgment
Use automation as draft input, not the final editor.
- **Release Drafter / autogenerated release notes** → good for PR grouping and starter bullets
- **Changesets** → good for package/version intent and monorepo release aggregation
- **release-please / semantic-release style flows** → good for release PRs, version bumps, and commit-driven summaries

Still decide manually:
- the primary audience
- what counts as notable
- what needs a migration link
- what should become a separate help/API/internal doc

### Step 8: Run the trust check before publishing
Use [references/release-note-quality-checklist.md](references/release-note-quality-checklist.md).

Verify:
1. Every claim matches shipped or merged evidence.
2. The chosen mode fits the audience and channel.
3. Breaking changes, removals, and deadlines are impossible to miss.
4. Route-outs stay explicit instead of bloating the note.
5. The packet is as small as possible while still truthful.

### Step 9: Return a brief or the finished artifact
Preferred brief shape before full drafting:

```markdown
# Release Writing Brief

## Mode
- Primary mode:
- Why it fits:
- Audience:
- Output shape:

## Evidence used
- Source of truth:
- Supporting docs / links:
- Assumptions / missing proof:

## Planned artifact packet
1. main release artifact
2. downstream sync / linked-doc follow-up

## Writing notes
- Breaking changes / deadlines:
- Route-outs kept out of scope:
- Channel-specific constraints:
```

If the user already asked for the finished artifact, produce the selected packet directly with the matching structure.

## Examples

### Example 1: Changelog plus migration link
**Input**
> Update `CHANGELOG.md` for v2.4.0 from the merged PR list and make the Basic Auth deprecation obvious.

**Good output direction**
- mode: `changelog`
- output shape: `summary-plus-links`
- grouped sections such as `Added`, `Changed`, `Deprecated`, `Fixed`
- migration link or placeholder instead of embedding the full auth procedure

### Example 2: Customer-facing release summary
**Input**
> Turn these shipped product updates into release notes customers will actually read.

**Good output direction**
- mode: `release-notes`
- output shape: `single-entry` or `summary-plus-links`
- benefit-led headings like `What’s new`, `Improvements`, `Fixes`
- route tutorials or help refreshes to `technical-writing`

### Example 3: Lightweight game patch notes
**Input**
> Write patch notes for our latest game update and keep them short.

**Good output direction**
- mode: `game-patch-notes`
- output shape: `patch-note-brief`
- concise sections for new content, tuning, fixes, and known issues
- route launch-event hype or campaign beats to `marketing-automation`

## Best practices
1. Start from shipped evidence, not vibes.
2. Pick one primary audience and one primary mode.
3. Use the smallest packet that fits the channel.
4. Separate release summary, migration detail, help docs, API docs, rollout mechanics, and launch messaging.
5. Let automation collect draft material, but do not outsource judgment.
6. Call out breaking changes and deadlines early.
7. Treat patch notes as a real workflow with player-facing constraints, not just a renamed changelog.
