${var} — Selects the mode and target:
- empty → in-repo changelog across every repo in
memory/watched-repos.md.owner/repo(bare slug) → in-repo changelog for that single repo only.push-to:owner/website-repo→ cross-repo mode: publish the product's merged PRs as a changelog PR onowner/website-repo(product repo comes frommemory/docs-sync.md).owner/product->owner/website(arrow form) → cross-repo mode with both product and website repos given explicitly.
A changelog is not a commit log. Raw commit dumps grouped by conventional prefix are the noise anti-pattern — users can't tell what matters. This skill produces a Keep a Changelog-style summary: categorized, plain-English, breaking changes surfaced, internal churn filtered out. It runs in two modes: in-repo (write the article into this repo) or push-to (open a changelog PR on a separate marketing/docs website repo).
Read memory/MEMORY.md and the last 3 days of memory/logs/ for context (prior runs, known issues). Before notifying, drop anything already reported in that window.
Parse ${var} to pick the branch:
${var} | Branch | Target |
|---|---|---|
| empty | A — in-repo | all repos in memory/watched-repos.md |
owner/repo (no push-to:, no ->) | A — in-repo | only that repo |
push-to:owner/website-repo | B — push-to | website = owner/website-repo; product = config product_repo |
owner/product->owner/website | B — push-to | product = owner/product; website = owner/website |
Disambiguation: a push-to: prefix or a -> arrow selects Branch B; anything else (empty or a bare owner/repo) selects Branch A. Then jump to the matching branch below.
Writes a categorized changelog article into this repo. No cross-repo PR; GH_GLOBAL is not needed here.
Reads repos from memory/watched-repos.md. If the file doesn't exist, abort and notify: "changelog: memory/watched-repos.md missing — nothing to scan." Do not create it silently.
# memory/watched-repos.md
- owner/repo
- another-owner/another-repo
If ${var} is set to a bare owner/repo, scan only that repo (skip the file list).
${var} is a bare owner/repo, scan only ${var}.memory/watched-repos.md and parse - owner/repo lines.For each repo, isolate failures — one broken repo must not kill the run. Track status in a sources dict (repo → ok|empty|fail).
Compute SINCE as UTC 7 days ago:
SINCE=$(date -u -d '7 days ago' +%Y-%m-%dT%H:%M:%SZ 2>/dev/null || date -u -v-7d +%Y-%m-%dT%H:%M:%SZ)
Detect the default branch (don't assume main):
BRANCH=$(gh repo view owner/repo --json defaultBranchRef --jq '.defaultBranchRef.name')
Fetch commits on the default branch since SINCE:
gh api -X GET "repos/owner/repo/commits" -f sha="$BRANCH" -f since="$SINCE" --paginate \
--jq '.[] | {sha: .sha, short: .sha[0:7], message: .commit.message, author: (.author.login // .commit.author.name), date: .commit.author.date, url: .html_url}'
Also fetch merged PRs in the window — PR titles/bodies are usually cleaner than raw commit messages:
gh pr list --repo owner/repo --state merged --limit 100 \
--search "merged:>=$SINCE" \
--json number,title,body,mergedAt,author,url,labels
Network note: gh uses GITHUB_TOKEN internally and works in a GitHub Actions run. If gh fails, log fail for that repo and continue — do not fall back to WebFetch (public API is rate-limited and adds noise).
Exclude before classifying:
dependabot[bot], renovate[bot], claude[bot], github-actions[bot].Keep a per-repo count of filtered commits for the footer ("N internal/bot commits hidden").
Do not use Features/Fixes/Docs/Chores — those are for developers. Use:
| Category | Use for |
|---|---|
| ⚠️ Breaking | feat!: / fix!: / any commit whose body contains BREAKING CHANGE:. Also any removed public API. |
| Added | New user-visible features (typically feat: without !). |
| Changed | Modifications to existing functionality users will notice (behaviour, UX, defaults). |
| Fixed | Bug fixes users care about (fix: only if the bug was observable). |
| Security | security: prefix, CVE-, dependency bumps flagged as security, or commits touching auth/crypto with obvious security framing. |
| Internal | Everything else (chore, ci, build, test, refactor, style, docs unless docs are user-facing). Show only a one-line count, not full entries. |
Deprecated and Removed categories: include only if genuinely present — don't pad with empty sections.
Commit message → changelog line rules:
type(scope): prefix. Keep scope only if it clarifies (dashboard: add dark mode is fine; core: fix bug is not).feat(auth): add oauth2 pkce flow → OAuth 2 PKCE login is now supported.[#123](url)) over sha; fall back to short sha ([a1b2c3d](url)).Save to output/articles/changelog-${today}.md:

Takes the product's recently merged PRs and publishes them as a changelog on the product's marketing/docs website, via a branch + PR on the website repo. The website is the public face — this keeps "what shipped" visible without anyone hand-writing release notes. This branch opens a cross-repo PR and requires GH_GLOBAL (a token with cross-repo write to the website repo). GITHUB_TOKEN alone only covers the current repo and cannot push to the website.
This branch is config-driven so the same file works in every instance. It reads which repos to use from memory/docs-sync.md; it never hardcodes repo names, handles, or commit identities.
Read memory/docs-sync.md. It defines:
product_repo — the repo whose merged PRs become the changelog (e.g. owner/product).website_repo — the Next.js marketing site to update (e.g. owner/product-website).min_prs (optional, default 1) — minimum number of new unpublished PRs required to publish an entry.lookback_days (optional, default 7) — only consider PRs merged within this many days. Bounds each entry to one window so a run never sweeps in months of history; matches the weekly schedule.draft (optional, default true) — open the website PR as a draft.git_user_name / git_user_email (optional) — commit identity for the website PR. Defaults to aeon / aeon@users.noreply.github.com.Apply the selector on top of config:
push-to:owner/website-repo → website_repo = owner/website-repo; product_repo from config.owner/product->owner/website → product_repo = owner/product, website_repo = owner/website (overrides config for this run).If neither the selector nor memory/docs-sync.md yields both a product repo and a website repo, exit with DOCS_SYNC_NO_CONFIG (notify + log, no PR). Seed a memory/docs-sync.md template (commented placeholder rows) so the operator can fill it in.
Compute the window cutoff first — lookback_days ago (default 7), as an ISO timestamp:
SINCE=$(date -u -d "${LOOKBACK_DAYS:-7} days ago" +%Y-%m-%dT%H:%M:%SZ 2>/dev/null || date -u -v-"${LOOKBACK_DAYS:-7}"d +%Y-%m-%dT%H:%M:%SZ)
Then fetch the last 50 closed PRs and keep only those merged within the window, newest merge first:
gh api "repos/${PRODUCT_REPO}/pulls" -X GET -f state=closed -f sort=updated -f direction=desc -f per_page=50 \
--jq "[.[] | select(.merged_at != null) | select(.merged_at > \"$SINCE\") | {number, title, url: .html_url, author: .user.login, merged_at, labels: [.labels[].name], body: (.body // \"\" | .[0:500])}] | sort_by(.merged_at) | reverse"
The window is the primary filter; the published-PR dedup in step B.2 is the idempotency guard against overlap and re-runs. Sandbox: if gh api fails transiently, retry once. Never use curl for the GitHub API — gh handles auth.
Clone the website repo and read the existing changelog data:
WORK_DIR="/tmp/docs-sync-work"
rm -rf "$WORK_DIR"
gh repo clone "$WEBSITE_REPO" "$WORK_DIR" -- --depth 20
cd "$WORK_DIR"
git config user.name "$GIT_USER_NAME"
git config user.email "$GIT_USER_EMAIL"
Pin the commit identity in the clone. A freshly cloned repo does NOT inherit the workflow's git identity, so without these two lines the commit author falls back to an improvised/unlinked email. Set GIT_USER_NAME / GIT_USER_EMAIL from memory/docs-sync.md (git_user_name / git_user_email); when the config omits them, default to aeon / aeon@users.noreply.github.com. Always pin it so every changelog commit + PR is attributed to one stable, intentional identity — never an improvised one.
If app/changelog-data.ts exists, read it and collect PUBLISHED_PR_NUMBERS (every PR number already in CHANGELOG). If it doesn't exist yet, this is a bootstrap run (see step B.4) and nothing is published.
Compute the new set: from step B.1's windowed PRs, keep only those whose number is NOT in PUBLISHED_PR_NUMBERS. PR number is the idempotency key — not dates — so re-running within the same window is always safe and never duplicates.
DOCS_SYNC_NOTHING_NEW (silent: log only, no PR, no notify).0 < count < min_prs → exit DOCS_SYNC_BELOW_THRESHOLD (log only, no PR). Lets PRs accumulate into a meaningful entry.Split the new PRs:
dependabot[bot] and titles starting chore(deps, chore(deps-dev), chore(actions), ci:, build:, style:. These get rolled into a single "Maintenance: N dependency/CI bumps" highlight, not listed individually.prs array so idempotency stays exact — but only the substantive ones get their own highlight bullet.Compose ONE ChangelogEntry:
date: ${today} (YYYY-MM-DD).title: 4–8 words naming the dominant theme of the batch (e.g. "i18n expansion + simulation fixes"). Derive it from the substantive PR titles, not boilerplate. Never "various improvements".summary: 1–2 plain-language sentences — what a builder following the project would care about. No hype, no "we're excited".highlights: one bullet per substantive PR (plus the single maintenance rollup if any). Each bullet ≤ 18 words, names the concrete change, ends with the PR ref (#N). Translate commit-speak into plain English.prs: every new PR as { number, title, url, author }.Banned phrases: "exciting", "robust", "leverage", "unlocks", "seamless", "we're thrilled", "stay tuned". They signal stock release-note filler.
The data file app/changelog-data.ts is the only file you mutate on a normal run. Its shape:
export type ChangelogPR = { number: number; title: string; url: string; author: string };
export type ChangelogEntry = {
date: string; // YYYY-MM-DD
title: string; // 4–8 word theme
summary: string; // 1–2 sentences
highlights: string[];
prs: ChangelogPR[];
};
export const CHANGELOG: ChangelogEntry[] = [
// newest first — PREPEND new entries here, never rewrite existing ones
];
export const PUBLISHED_PR_NUMBERS = CHANGELOG.flatMap((e) => e.prs.map((p) => p.number));
Normal run: prepend the new entry to the top of the CHANGELOG array. Touch nothing else.
Bootstrap run (no app/changelog-data.ts yet) — create the changelog surface, matching the site's existing conventions (do NOT invent a new design system):
app/changelog-data.ts with the schema above + your first entry.app/changelog/page.tsx that renders CHANGELOG. Read an existing list page first (app/blog/page.tsx is the model on these sites) and reuse its shared chrome: same SiteNav/SiteFooter, the same CSS module it imports (e.g. ../docs/page.module.css as chrome), the same hero/section structure. Wire full Next.js metadata (title, description, canonical, OpenGraph) like the other pages. Give it a JSON-LD block if the blog page has one.app/docs/page.tsx: import CHANGELOG from ../changelog-data and render the latest 3 entries inline, with a "Full changelog →" link to /changelog. Place it near the top of the docs body, after the intro. Keep edits to that file minimal and self-contained.changelog link to the primary nav in app/site-chrome.tsx (or wherever the site renders its nav — check the layout if there's no site-chrome).Match indentation, quote style, and naming of each repo exactly. After editing, if the site has a typecheck/lint/build available, run it (npm run lint / npx tsc --noEmit / npm run build) and fix any error your change introduced. If npm isn't available in the run, skip silently — note it in the PR body.
BRANCH="aeon/changelog-${today}"
git checkout -b "$BRANCH"
git add -A
git commit -m "docs(changelog): sync N merged PRs from ${PRODUCT_REPO}"

Open the PR on the website repo (draft unless config says otherwise):
gh pr create --repo "$WEBSITE_REPO" --draft \

Use --draft when draft config is true (the default). Build the PR body from the real entry — never leave placeholders.
Send only on DOCS_SYNC_OK / DOCS_SYNC_BOOTSTRAP (a real entry was written) and on DOCS_SYNC_NO_CONFIG (one-line config prompt). Stay silent on DOCS_SYNC_NOTHING_NEW / DOCS_SYNC_BELOW_THRESHOLD.

Consolidate both branches under ONE ### changelog heading in memory/logs/${today}.md, with a Mode: discriminator line naming which branch ran.
Branch A — in-repo:

gh CLI handles auth internally and works in a GitHub Actions run.
Branch A (in-repo): if gh api fails for a repo, mark it fail in the sources dict and continue with other repos — don't abort the whole run, and don't fall back to unauthenticated WebFetch (rate limits will cascade failures). This branch uses only GITHUB_TOKEN — no GH_GLOBAL needed.
Branch B (push-to): GitHub Actions runs Claude Code in a non-interactive sandbox.
gh api / gh pr create / gh repo clone — never curl. gh works because it handles auth internally, so no token touches the command line.&&, ||, |, ;) and $(...)/$VAR expansion in skill bash blocks. Split into separate calls; the working directory persists, so run cd "$WORK_DIR" as its own call then run commands. Compute literal values (repo names, branch) in your reasoning, not via shell substitution.npm run build/lint isn't available or fails, skip it and note "build not verified" in the PR body rather than aborting.GH_GLOBAL (a token with cross-repo write to the website repo) — only this branch needs it. GITHUB_TOKEN alone only covers the current repo and cannot push to the website.
