Sync Projects

You reconcile src/content/projects/*.mdx with the user's public GitHub repositories. The skill is deliberately non-interactive: it scans, decides, acts, commits, pushes, and reports. If the sync produced bad output, the recovery path is git revert HEAD (and git push if already published).

Hard rule: no em dashes or en dashes

NEVER write em dashes or en dashes anywhere in any field you generate (descriptions, body prose, anything). Use hyphens only for compound modifiers. The space-hyphen-space pattern (-) used as a clause separator is an em-dash substitute and is forbidden. Use commas, colons, parentheses, or split sentences.

Pre-flight: abort conditions

Stop and tell the user before doing anything if any of the following are true:

1. git status --porcelain returns non-empty output. Tell the user to commit or stash first. The skill makes a commit; running on a dirty tree risks mingling unrelated edits.
2. gh auth status fails. The user must run gh auth login first.
3. gh api user --jq .login does not return agigante80. Wrong account is configured.

Configuration (edit inline as needed)

Helper: slug normalisation

GitHub repo names mix case and use both _ and -. Portfolio slugs are lowercase with -. Use this normalisation everywhere a GH repo is matched to a local MDX:

normalise(name) = name.lower().replace('_', '-')

Examples that must match:

• OndaHertz_es (GH) → ondahertz-es matches MDX slug ondahertz-es
• AgentGate (GH) → agentgate matches MDX slug agentgate
• SafeHarbor-Media-Stack (GH) → safeharbor-media-stack matches MDX slug safeharbor-media-stack

Failing to normalise causes the first sync to flag every existing project as both ORPHAN (no GH match) and NEW (GH repo not in portfolio).

Steps

1. Fetch GitHub state

gh api users/agigante80/repos --paginate \
  --jq '.[] | {name, description, fork, archived, pushed_at, stargazers_count, forks_count, default_branch, homepage, topics, language}'

For every candidate that survives filtering in step 2, also verify a README exists:

gh api "repos/agigante80/<name>/readme" --jq '.download_url' 2>/dev/null

2. Apply filters

The fork filter applies only to NEW candidates, not to lookups for existing portfolio entries. (Some portfolio projects are forks, e.g. galena-es; orphaning them is wrong.)

Build two sets:

Filtered candidates (for considering NEW additions):

• fork == false
• name (normalised) is not in IGNORE_REPOS
• description is non-empty
• README fetch succeeded
• archived == false

Lookup set (for "is this GH repo backing an existing MDX?"):

• ALL non-ignored repos, including forks and archived ones
• Used in step 4 matching

3. Read local MDX inventory

For each src/content/projects/*.mdx:

• Parse YAML frontmatter
• Extract: githubUrl, current tier, current status, lastSyncedFrom (ISO 8601 timestamp or absent), current body (everything after the closing ---)
• Derive the GH repo name from githubUrl by splitting on / and taking the last segment, then apply normalise(). This is the key used to match against GH repos.

lastSyncedFrom is the operational signal for "have we already pulled this state from GitHub?". It is written by this skill on every NEW / UPDATE / ARCHIVE action and never edited by humans. Absent means "never synced" and triggers a full UPDATE on the next run. Comparing against file git mtime (the old approach) was unreliable: any schema migration that touched every MDX would reset the signal for every project.

4. Classify each GitHub repo

Match using normalise() on both sides. Comparison uses MDX lastSyncedFrom (not file mtime).

Also produce an ORPHAN list: every MDX whose normalised repo name is not in the full GH lookup set (deleted on GitHub, or repo renamed).

5. Fetch multi-signal engagement (for every classified project + every portfolio project that was skipped)

The same fetcher feeds tier-suggestion logic in step 7. Run it once per project, store the results.

For each project, gather:

Ownership verification (critical): npm and PyPI package names collide. The npm package agentgate exists but belongs to "Luis Montes," not Andrea. Verify by fetching the package metadata and checking that the source repository URL matches https://github.com/agigante80/<name> (normalised comparison). Examples:

• npm: npm view <pkg> repository.url → must contain agigante80/<name>
• PyPI: curl https://pypi.org/pypi/<pkg>/json | jq '.info.project_urls' → "Source" or "Homepage" must contain agigante80/<name>

If verification fails, do not count the downloads. Record as null, not zero.

6. Execute actions

For each NEW / UPDATE / ARCHIVE item, do exactly the following.

NEW (auto-add a fresh project at Tier 3)

• Slug: normalise(repo_name) (lowercase, hyphenated)
• Fetch README content:

  gh api "repos/agigante80/<name>/readme" --jq '.content' | base64 -d

• Derive description: rewrite GH description in portfolio voice. Max 160 chars. No em/en dashes.
• Derive techStack: GH language + GH topics that look like tech labels.
• Derive status: active if pushed_at within 30 days, else maintained.
• Derive category: best match from [AI/MCP, Security, Finance, Utilities, Content] based on topics and description. Default Utilities.
• Find a hero image in README: parse the first ![...](...) whose URL does NOT contain any of shields.io, badge.fury.io, /badge/, badges., or badge in the path. Resolve relative URLs against https://raw.githubusercontent.com/agigante80/<name>/<default_branch>/. Create the folder first (mkdir -p src/assets/images/projects/<slug>), download to src/assets/images/projects/<slug>/hero.<ext>, and verify > 10 KB. Keeping it under src/assets/ lets Astro optimize it (WebP, responsive srcset, intrinsic dimensions).
• Suggest related articles: load src/lib/articles.ts, do case-insensitive substring matching on each article's title, description, and tldr against the project name (and common variants: with/without hyphens, with/without "MCP" suffix, etc.). Collect article slugs whose text mentions the project. If matches found, add them to relatedArticles. Skip if no matches; do not invent links.
• Write src/content/projects/<slug>.mdx. Frontmatter only, no body:

  ---
  title: "<repo name, prettified>"
  description: "<one sentence, ≤160 chars>"
  category: "<derived>"
  tier: 3
  status: "<derived>"
  techStack: [...]
  githubUrl: "https://github.com/agigante80/<name>"
  liveUrl: "<GH homepage if present>"   # omit if absent
  featured: false
  heroImage: "../../assets/images/projects/<slug>/hero.<ext>"   # path RELATIVE to the MDX file (content-collection image() helper optimizes it); omit if no hero found
  relatedArticles: [...]   # omit if empty
  lastSyncedFrom: "<now, ISO 8601 with Z suffix>"
  ---

UPDATE (refresh an existing project)

• Read existing frontmatter and body
• Preserved fields (do not overwrite): title, category, tier, featured, metrics, relatedArticles
• Refreshed fields:
  • description: regenerate from current README first paragraph + GH description. Max 160 chars. No em/en dashes.
  • techStack: regenerate from current GH primary language + topics
  • status: derive from pushed_at and archived
  • githubUrl: refresh in case GH renamed the repo
  • liveUrl: refresh from current GH homepage
  • heroImage: if the README's hero image URL has changed OR the current heroImage file does not exist, re-download. Otherwise leave alone.
  • lastSyncedFrom: set to the current ISO 8601 timestamp (with Z suffix). This is what stops the next run from re-classifying as UPDATE.
• Body handling (soft regen):
  • Body empty: leave empty
  • Body starts with SOFT_REGEN_MARKER: regenerate body using the standard H2 scaffold (What is X / The Problem / How I Built It / optional Architecture / Impact), pulling current README content for hints. Keep the marker at the top.
  • Marker absent: leave body untouched (user has taken ownership)

ARCHIVE (mark an existing project as archived)

• Read existing MDX
• Update status: line to "archived"
• Update lastSyncedFrom to the current ISO 8601 timestamp
• No other changes

ORPHAN

• Take no action
• Add to report with the reason ("no matching GH repo for <slug> (was <githubUrl>)")

7. Tier-vs-popularity suggestions (multi-signal, no action)

For every project in the (post-sync) portfolio, use the engagement signals fetched in step 5 to decide.

A signal is notable if its value meets or exceeds the notable threshold for its type. A signal is outlier if its value meets or exceeds the outlier threshold for its type.

Rules:

The skill never changes tier. These are text suggestions only.

8. Build gate, commit and push

If no writes occurred in step 6 (everything was current), skip commit. Otherwise, run a local build first and confirm it succeeds. This is the schema validator: a malformed heroImage path (it must be relative to the MDX file for the image() helper) or any other bad frontmatter fails here rather than breaking the Cloudflare deploy. Never push a red build.

npm run build
git add -A
git commit -m "chore(sync): N added, M updated, K archived from github.com/agigante80"
git push origin main

Replace N, M, K with actual counts. If the build fails, fix the offending frontmatter (or drop the hero) and rebuild before committing.

9. Report

Print to the user:

• Summary line: N added | M updated | K newly archived | W orphaned
• Per-bucket detail (only sections with items):
  • Added: slug, status, hero y/n, related-articles count
  • Updated: slug, what changed (description / techStack / status / hero / body-regen)
  • Archived: slug
  • Orphaned: slug + reason
• Engagement table for every portfolio project (post-sync), with columns: slug, tier, stars, forks, npm/mo, pypi/mo, docker pulls. Use - for null (no published package or ownership not verified) and 0 for verified-but-zero.
• Tier suggestions (if any), each citing which signals fired
• Commit hash (or (no changes))

What this skill explicitly does NOT do

• Promote tier. Tier is your editorial decision. The skill suggests, never acts.
• Touch hand-edited bodies. Bodies without the soft-regen marker are owned by you.
• Delete MDX files for repos missing from GitHub. Renames look like deletions; the skill flags them as orphans for your review.
• Run on a schedule. Manual invocation only.
• Generate prose for new auto-added Tier 3 projects. New projects get frontmatter only.
• Count downloads from unverified packages. A package name on npm or PyPI matching your repo slug is not enough; the source URL must match agigante80/<name> too.
• Embed shields.io badges, license badges, CI badges, or any badge wall. Same opinionation as /manage-project.

Recovery

If the sync produced unwanted changes:

git revert HEAD
git push origin main

One commit per sync means one revert undoes everything. If you have not yet pushed, git reset --hard HEAD~1 also works.
