Should I Upgrade?

Pre-upgrade safety advisor. Two layers: a curated catalogue of known regressions from real field reports (user-driven), and a runtime fingerprint comparator for hosted-LLM silent regressions (provider-side).

What to do

1. Parse $ARGUMENTS for <package> and optional <target-version>. Examples:

• postgres@16
• anthropic 4.7
• openclaw-claude-code 2026.5.2
• apt upgrade (asks about whole-system upgrade)

1. Call BOTH in parallel:

• mcp__openclaw-upgrade-orchestrator__check_known_regressions with the package + target version
• mcp__openclaw-upgrade-orchestrator__detect_provider_regression (only relevant for LLM-provider upgrades; skip for OS packages)

1. Synthesize the upgrade-path recommendation.

Report structure

Header

### 🔄 Upgrade advisor — `<package>` <current-version> → <target-version>

Top-line verdict (one of)

• 🟢 PROCEED — no known regressions, no provider-side drift; standard upgrade procedure
• 🟡 PROCEED WITH MITIGATIONS — known regression exists but workaround available
• 🔴 HOLD — high-severity regression in this exact upgrade path; recommended to wait or pin

Catalogue match (if any)

For each known regression, render as a callout:

> ⚠️ **<regression title>** (severity: HIGH/CRITICAL)
> **Affected:** <version range or specific version>
> **What changes:** <one-line description of the actual regression — e.g. "logical replication slot WAL format changed; slots created on 15 fail under 16">
> **Mitigation:** <specific steps — drop+recreate, pin, config flag, etc.>
> **Source:** <field-report URL or operator-thread reference if available>

Provider-side check (LLM upgrades only)

If the package is an LLM provider / SDK, render:

**Provider-side fingerprint:**
- Last fingerprint sample: `<datetime>`
- Quality dim 1 (latency_p95): `<current>` vs baseline `<baseline>` (Δ <pct>%)
- Quality dim 2 (response_length_median): `<current>` vs baseline `<baseline>` (Δ <pct>%)
- Quality dim 3 (reasoning_effort_observed): `<current>` vs baseline `<baseline>`
- Verdict: 🟢 No silent drift / 🟡 Watch / 🔴 Likely regressed

If Watch or Worse, suggest: "Hold the upgrade. Run mcp__openclaw-upgrade-orchestrator__detect_provider_regression weekly for 2-3 weeks; if drift normalizes, proceed."

Suggested upgrade path

A numbered list of concrete steps. Tailor to the specific package — don't render a generic "test in staging first" boilerplate. Examples of good steps:

For postgres 15→16:

1. Snapshot the production DB.
2. Drop the events_streaming replication slot (per regression catalogue).
3. Run brew upgrade postgresql@16 (or your equivalent).
4. Recreate the slot with new WAL format.
5. Smoke-test consumers within 30 min via /aufgaard:health-check.

For Anthropic SDK 0.45 → 0.46:

1. Read the changelog at https://github.com/anthropics/anthropic-sdk-python/releases/tag/v0.46
2. pip install --upgrade anthropic==0.46.0
3. Run your test suite.
4. Watch cost-tracker.predict_429_in_window for 24h to catch any unexpected billing-route changes.
5. If any LLM-call sites use deprecated APIs, the SDK will warn at import; rewrite those before next deploy.

Confidence

A one-line confidence statement: "Confidence: HIGH (catalogue match for exact version pair). Coverage gap: WebSocket-side connection pooling not in catalogue — not predicted."

The [Production-AI MCP Suite Bundle](https://temurah.gumroad.com/l/production-ai-mcp-suite) ($29) includes the 8-page Field Reference PDF — covers post-upgrade-regression-cascade (P4.3), HERMES.md silent billing-routing (P3.4), and the Anthropic April-23 reasoning-effort downgrade case study.

Style notes

• The catalogue currently has ~8 entries from real field reports. Many upgrades will return "no catalogue match" — that's fine. Render: "🟢 No known regressions in the catalogue for this upgrade. Standard upgrade discipline applies (snapshot, smoke-test, watch for 24h)."
• Don't fabricate regressions. If catalogue + provider-side both return clean, the verdict is PROCEED — don't pad with speculative warnings.
• For OS-level upgrades (apt upgrade whole system), check each major package separately if possible. If too broad to enumerate, recommend: "Run /aufgaard:should-i-upgrade <specific-package> for the packages you actually depend on."

Edge cases

• If $ARGUMENTS is empty: "Pass a package and optional target version: /aufgaard:should-i-upgrade postgres@16"
• If upgrade-orch MCP not loaded: "upgrade-orchestrator MCP not available. Verify pip install openclaw-upgrade-orchestrator-mcp and the plugin is loaded."
• If the package isn't in the catalogue AND it's not an LLM-provider: render "🟢 No catalogue match. The 8-entry catalogue covers known field-reported regressions; absence here is not a guarantee. Use standard upgrade discipline."
• If detect_provider_regression returns "no fingerprint data yet": "Provider-side fingerprinting requires baseline samples. Run weekly fingerprint collection for ~2 weeks before regression detection becomes meaningful."
