name	release-docs
description	Generate a combined release blog post for ai-platform-engineering. Produces a single docs/releases/YYYY-MM-DD-release-X-Y-Z.md file containing release notes and the upgrade guide (migration guide) inline. Use when cutting a release, when a user asks "what changed in 0.4.x", or when upgrading their values.yaml to a new chart version.

Release Blog Post Generator

Produce one combined blog post for an ai-platform-engineering release:

docs/releases/YYYY-MM-DD-release-X-Y-Z.md — release notes narrative (highlights, what's new, bug fixes, breaking changes) followed by the full upgrade guide (Helm values diff, step-by-step runbook, personal impact analysis) as an embedded section.

The file is picked up by the Docusaurus releases blog plugin and published at /blog/releases/release-X.Y.Z.

---

Execution context

Runs in two modes:

• Coding agent (Claude Code, Cursor) with shell access — run git and helm commands directly and write the file to disk.
• Chat-only (CAIPE chat, Slack, web UI) — render output as a fenced markdown block the user can copy; note which commands to run manually.

Detect by whether a Bash/shell tool is available.

---

Step 1 — Gather inputs

Ask the user for:

Input	Example	Required
To version	0.4.9	Yes
From version	0.4.8	Yes (defaults to previous tag)
User's values.yaml	paste or path	No — enables personal impact analysis
Environment	dev / preview / prod / vm	No — enables env-specific notes

If from/to are not provided, detect from the repo:

git tag --sort=-version:refname | grep -E '^[0-9]+\.[0-9]+\.[0-9]+$' | head -2

---

Step 2 — Collect raw data

Run all of the following in parallel where possible.

2a — Git log between versions

git log <from>..<to> --oneline --no-merges

Fetch full PR bodies for non-chore commits:

# for each PR number in the log, e.g. (#1324):
gh pr view <number> --json title,body,labels

2b — Helm values diff

CHART=oci://ghcr.io/cnoe-io/charts/ai-platform-engineering
helm show values "$CHART" --version <from> > /tmp/values-from.yaml
helm show values "$CHART" --version <to>   > /tmp/values-to.yaml
diff -u /tmp/values-from.yaml /tmp/values-to.yaml

2c — Chart metadata

helm show chart "$CHART" --version <to>

2d — CHANGELOG.md

sed -n '/^## <to>/,/^## <from>/p' CHANGELOG.md

---

Step 3 — Classify changes

Classify git commits

Type	Criteria
Feature	feat(*) commits
Fix	fix(*) commits
Security	commits touching Dockerfile, securityContext, PSS/PSA
Breaking	commit body contains "BREAKING CHANGE" or PR label breaking-change
Chore / Internal	chore, refactor, ci, test — omit from user-facing notes

Classify Helm values diff lines

Category	Criteria
Breaking	Key renamed, removed, or type changed
New required	New key with no default
New optional	New key with working default
Deprecated	Key still works but will be removed
Default changed	Same key, different default value

---

Step 4 — Write docs/releases/YYYY-MM-DD-release-X-Y-Z.md

Use the date the tag was pushed (or today's date if cutting now).

---
slug: release-<to>
title: "Release <to> — <2-5 word subtitle capturing the biggest change>"
date: <YYYY-MM-DD>
authors: [sriaradhyula]
tags: [release]
---

## Highlights

<2-4 sentence narrative of the most significant changes in plain English.
Focus on operator/user impact, not internal implementation details.>

<!-- truncate -->

## What's New

### <Feature area 1>
- **<Title>** — <one-line description linking to PR #NNNN>

### <Feature area 2>
- ...

## Bug Fixes

- **<scope>**: <description> ([#NNNN](https://github.com/cnoe-io/ai-platform-engineering/pull/NNNN))

## Security

<Any security-context, PSS, or CVE-related changes. Omit section if none.>

## Breaking Changes

<If none:>
No breaking changes. Drop-in upgrade from <from>.

## Known Issues

<If none:>
None known at this time.

---

## Upgrade Guide: <from> → <to>

### Overview

<One paragraph: overall theme, e.g. "Drop-in upgrade — no values.yaml edits required.">

### Helm Values Changes

<If no diff:>
No Helm values changes between <from> and <to>. Drop-in upgrade.

<If diff exists, use these subsections:>

#### Breaking Changes

**Affected key**: `global.foo.bar`

**Before (<from>)**:
```yaml
global:
  foo:
    bar: "old-value"

After ():

global:
  foo:
    bar: "new-value"

Action: Update your values.yaml. If left unchanged, .

New Optional Fields

Env Var / Key	Default	Description
TOOL_CALL_LIMIT	0 (disabled)	Max tool invocations per run

Deprecated / Removed Keys

Key	Removed in	Replacement
tags.old-key		global.newKey

Upgrade Runbook

1. Update chart version

helm upgrade ai-platform-engineering \
  oci://ghcr.io/cnoe-io/charts/ai-platform-engineering \
  --version <to> \
  -f your-values.yaml

2. Apply values.yaml changes

3. Verify

kubectl get pods -n <namespace>

Step 5 — Write file to disk (coding agent)

mkdir -p docs/releases

cat > docs/releases/<YYYY-MM-DD>-release-<X-Y-Z>.md << 'EOF'
<generated content>
EOF

---

Step 6 — Snapshot and prune Docusaurus versions (coding agent)

After writing the blog post, snapshot the current docs/ tree as the new version and prune old snapshots to stay within the retention policy.

Retention policy:

• Latest 5 releases from the current minor series (e.g. 0.4.7–0.4.11)
• Highest release from each previous minor series (e.g. 0.3.11, 0.2.x)

Run from repo root:

NEW_VERSION=<to> node docs/scripts/snapshot-and-prune-versions.js

This script:

1. Runs docusaurus docs:version <to> — snapshots docs/ into versioned_docs/version-<to>/
2. Prunes versioned_docs/, versioned_sidebars/, and versions.json to the retention policy
3. Updates docs/versions-config.json — sets lastVersion, marks <to> as (Latest), removes pruned entries

Commit all release artifacts together:

git add docs/releases/<YYYY-MM-DD>-release-<X-Y-Z>.md
git add docs/versioned_docs/ docs/versioned_sidebars/
git add docs/versions.json docs/versions-config.json
git commit -s -m "docs: release <to> — blog post, docs snapshot, version prune"

Guidelines

• <!-- truncate --> goes immediately after the Highlights section so the blog list shows just the intro paragraph
• Show concrete before/after YAML for every breaking change — never prose-only
• For breaking changes, state the consequence of not updating
• Keep the upgrade runbook linear — steps should be self-contained
• If helm show values is unavailable, ask the user to paste output — never guess
• Highlight environment-specific notes (VM kind clusters use standard storageClass; EKS uses gp2/gp3)
• For ExternalSecret additions, list the exact Vault path and key the chart now expects
• Omit chore, ci, test, and refactor commits from user-facing notes
• If there are zero helm value changes, say so explicitly and reassure it is a drop-in upgrade
• Do NOT create separate migration guide files — the upgrade guide lives inside the release post
