Diagnose Deployment Agent Skill

> Plugin check: Run node "${PLUGIN_ROOT}/scripts/check-version.js" — if it outputs a message, show it to the user before proceeding.

diagnose-deployment

Surfaces and pattern-matches deployment errors against a known failure catalog. For each identified error with an available auto-fix, asks explicit user permission before applying any changes. Never auto-applies fixes without confirmation.

Prerequisites

• Project root with powerpages.config.json
• PAC CLI installed (will report if missing)

Phases

Phase 1 — Verify Prerequisites and Locate Project

Create all tasks upfront at the start of this phase.

Tasks to create:

• "Verify prerequisites and locate project"
• "Collect deployment artifacts"
• "Surface upload errors"
• "Query solution import status"
• "Diagnose and categorize findings"
• "Offer auto-fixes"
• "Present findings summary"

Steps:

• Locate project root: search for powerpages.config.json in cwd and parent directories
• Check PAC CLI: pac --version (report version or "not installed")
• Check PAC CLI auth: pac env who (report environment URL or "not authenticated")
• Check Azure CLI: az account show (report subscription or "not logged in")

Auth failures are non-blocking — report them as findings, continue collecting other artifacts.

Phase 1.5 — Ground in current ALM documentation

> Reference: ${PLUGIN_ROOT}/references/alm-docs-grounding.md

Cap this step at ~30 seconds. If MCP search / fetch errors out, log a one-line note and continue — this skill must remain runnable offline.

• Run microsoft_docs_search with the query: Power Pages deployment errors solution import troubleshooting.
• Fetch https://learn.microsoft.com/en-us/power-platform/alm/solution-concepts-alm (and at most one sister page on troubleshooting or known import errors) in parallel via microsoft_docs_fetch.
• Extract a one-paragraph summary of what Microsoft Learn currently says about common deployment failures and their resolution. Compare against ${PLUGIN_ROOT}/references/deployment-error-catalog.md and flag any new error patterns not yet captured in the catalog.
• Use the summary to inform pattern-matching in Phase 5. If a new pattern is documented on Learn that isn't in the catalog, surface it to the user as a candidate addition rather than silently extending the catalog.

Phase 2 — Collect Deployment Artifacts

Gather all available context:

• Read powerpages.config.json — extract siteName, websiteRecordId, compiledPath
• Check .powerpages-site/ folder exists
• Glob for manifest files: .powerpages-site/*-manifest.yml — list all found, note their environment hostnames
• Check if .solution-manifest.json exists (for solution-related diagnostics)
• Check if docs/alm/last-import.json exists (for recent import failures)
• Check build output: confirm {compiledPath}/ exists and is non-empty

Report: "Found project: {siteName}. Artifacts collected."

Phase 3 — Surface Upload Errors

Re-run pac pages upload-code-site in capture mode to get fresh error output:

pac pages upload-code-site --rootPath "." 2>&1

> Note: This intentionally triggers the upload to capture any errors. If the upload succeeds cleanly, that is also a valid diagnostic result ("no errors found").

Capture stdout+stderr as a single string. Pass to scripts/parse-deployment-errors.js:

echo "{escaped-output}" | node "${PLUGIN_ROOT}/scripts/parse-deployment-errors.js"

Parse the JSON findings array. If the upload succeeded with no errors, note this and skip to Phase 5 with an empty findings list.

Phase 4 — Query Solution Import Status

Only run if .solution-manifest.json exists.

• Acquire Azure CLI token for environment URL
• Check recent async operations (last 24 hours):

   GET {envUrl}/api/data/v9.2/asyncoperations?$filter=statecode eq 3 and statuscode eq 31 and createdon gt {yesterday}&$select=asyncoperationid,name,message,friendlymessage,statuscode,completedon&$orderby=completedon desc&$top=5

• Check recent import jobs:

   GET {envUrl}/api/data/v9.2/importjobs?$select=solutionname,completedon,progress&$orderby=completedon desc&$top=3

• If failed operations found, pass each message field through parse-deployment-errors.js

Skip gracefully if auth is not available (auth failure in Phase 1).

Phase 5 — Auto-Diagnose Known Issues

Consolidate all findings from Phases 3 and 4. For each finding, categorize:

• Error: Blocks deployment
• Warning: May cause issues
• Info: Informational

Also add findings for missing artifacts discovered in Phase 2:

• Missing websiteRecordId → Error (patternId: missing-website-record-id)
• Empty build output → Error (patternId: empty-build)
• Multiple environment manifests → Warning (may indicate environment confusion)

Present all findings in a table:

| # | Severity | Type | Issue | Auto-fix? |

|---|---|---|---|---|

| 1 | Error | upload | JavaScript uploads blocked | Yes |

| 2 | Warning | config | Multiple manifest files found | No |

Phase 6 — Offer Auto-Fixes

For each Error finding with autoFixAvailable: true, in order:

<!-- gate: diagnose-deployment:6.auto-fix | category=consent | cancel-leaves=nothing -->

> 🚦 Gate (consent · diagnose-deployment:6.auto-fix): Per-finding consent before applying any auto-fix. Loops once per Error finding with autoFixAvailable: true — each finding gets its own Yes / No / Skip-all AskUserQuestion. The pattern ID surfaces in the prompt. Never batch fixes — three findings = three separate consent prompts (unless the user picks "Skip all" on the first, which short-circuits the loop). The Yes from finding 1 does NOT cover finding 2; each fix has its own blast radius (different files, different settings, different reversibility).

• Explain the issue and proposed fix
• Ask explicit permission via AskUserQuestion:

> "Issue: {message}

> Proposed fix: {suggestedFix}

> Apply this fix? Yes / No / Skip all auto-fixes"

• If approved, execute the fix:

stale-manifest: Delete *-manifest.yml file(s) in .powerpages-site/

   # Ask which manifest to delete if multiple found, then:
   rm ".powerpages-site/{manifestFile}"

blocked-js: Update blockedattachments setting

   # Get current setting first
   pac env list-settings | grep -i blocked
   # Remove .js from the blocked list (preserve other blocked types)
   pac env update-settings --name blockedattachments --value "{updated-value}"

missing-website-record-id: Retrieve and update record ID

   pac pages list
   # Parse output, find matching site by name, then update powerpages.config.json

auth-expired: Guide re-authentication

   pac auth create --environment "{envUrl}"
   az login

empty-build: Run build

   npm run build

• After each fix, re-run the relevant check to verify it resolved the issue. Update finding status to "Fixed" or "Manual required".

> Key Constraint: Never apply any fix without explicit user permission. Each fix requires a separate confirmation.

Phase 7 — Present Findings Summary

Display a final summary table of all findings:

| # | Severity | Type | Issue | Status |

|---|---|---|---|---|

| 1 | Error | upload | JS uploads blocked | Fixed |

| 2 | Error | config | Missing websiteRecordId | Manual required |

| 3 | Warning | config | Multiple manifest files | Informational |

Status values:

• Fixed: Auto-fix was applied and verified
• Manual required: No auto-fix available — show manual steps
• Skipped: User declined the fix
• Informational: Warning/Info, no action needed

If all errors are resolved: suggest retrying deployment with /power-pages:deploy-site.

If manual steps remain: list them explicitly with commands or links.

Record Skill Usage

> Reference: ${PLUGIN_ROOT}/references/skill-tracking-reference.md

Follow the skill tracking instructions in the reference to record this skill's usage. Use --skillName "DiagnoseDeployment".

Key Decision Points (Wait for User)

• Phase 6: Each individual auto-fix requires explicit confirmation before applying
• Phase 6: If user says "Skip all auto-fixes", stop offering fixes and go to summary

Error Handling

• If pac pages upload-code-site produces no output: report "No upload errors detected in current state"
• If Azure CLI token unavailable: skip Phase 4, note in summary
• If parse-deployment-errors.js returns no findings: report "No known error patterns detected" and show raw output for manual review
