Supply Chain Refresh

Supply Chain Refresh

Automated skill supply chain maintenance.

I. Philosophy

A supply chain is only as good as its refresh rate. Community skills evolve — repos add new skills, fix bugs, and improve documentation. This skill runs the full scan-normalize-package pipeline on a scheduled or manual basis, producing a diff report that shows what changed since the last run.

II. When to Use

• On a weekly schedule to keep the skill library current
• After adding new repos to the watched list
• When a community repo announces a new release
• Before publishing to OCI (Action 7) to ensure latest versions

III. Workflow

Step 1: Load Watched Repo List

Read the repo list from the supply chain manifest:

/AgenticStackOrchestration/specs/starred-repos-supply-chain/manifest.json

Extract source_repos array. Also check for any newly starred repos:

gh api user/starred --jq '.[].full_name'

Step 2: Pull Latest

For each repo:

1. If already cloned: git pull --ff-only
2. If new: git clone --depth=1
3. Record: commit SHA before and after pull

Step 3: Scan for Changes

Run scan-community-repos on all repo paths. Compare new catalog against previous manifest.json:

• New skills: present in scan, absent in manifest
• Updated skills: present in both, content hash differs
• Removed skills: present in manifest, absent in scan

Step 4: Normalize New/Updated Skills

For each new or updated skill:

1. Run normalize-community-skill
2. Copy to staging directory

Step 5: Package

Run dojo skill package-all on staging directory. Only new/updated skills will get new CAS entries (content-addressed = idempotent for unchanged content).

Step 6: Generate Diff Report

# Supply Chain Refresh Report
Date: {timestamp}
Previous run: {last_manifest_date}

## Changes
- New skills: {count} ({names})
- Updated skills: {count} ({names})
- Removed skills: {count} ({names})
- Unchanged: {count}

## New Skill Details
| Name | Source | Tier | CAS Hash |
|------|--------|------|----------|

Step 7: Update Manifest

Overwrite manifest.json with new state.

IV. Best Practices

1. Always pull before scanning. Stale clones produce false "unchanged" reports.
2. Preserve the previous manifest. Archive it as manifest-{date}.json before overwriting.
3. Rate-limit git operations. Space clones 1s apart to avoid GitHub rate limits.
4. Log everything. The diff report is the audit trail for what entered the skill library.

V. Quality Checklist

• All watched repos pulled successfully (or failures logged)
• Scan catalog compared against previous manifest
• New/updated skills normalized and packaged
• Diff report generated with complete change summary
• Manifest.json updated with new state
• Previous manifest archived

Output

• A Supply Chain Refresh Report (markdown) showing new, updated, removed, and unchanged skill counts with a details table for new skills (name, source repo, tier, CAS hash).
• An updated manifest.json at /AgenticStackOrchestration/specs/starred-repos-supply-chain/manifest.json.
• A archived copy of the previous manifest saved as manifest-{date}.json before overwriting.

Examples

Scenario 1: "Weekly skill library maintenance" → 3 repos pulled, scan finds 2 new skills and 1 updated. Both new skills normalized and packaged into CAS. Report shows 495 → 497 community skills. Manifest updated. Scenario 2: "A community repo announced a new release with 5 new skills" → Targeted pull of that repo, scan detects all 5 as new (absent in manifest). All 5 normalized and packaged. Diff report generated listing names, source, and CAS hashes.

Edge Cases

• If a repo pull fails (rate limit, auth, network), log the failure but continue processing the remaining repos — a partial refresh with a complete failure log is better than a failed run.
• Content-addressed storage (CAS) is idempotent for unchanged content — re-running on the same state produces no new CAS entries, making the operation safe to re-run.

Anti-Patterns

• Scanning before pulling — stale clones produce false "unchanged" reports that hide new skills from recently updated repos.
• Overwriting manifest.json without archiving the previous version — without the archive, diffs cannot be reconstructed and the audit trail is broken.
