Package Upgrade

Codex compatibility note:

>

- Invoke repository skills with $skill-name in Codex; this mirrored copy rewrites legacy Claude /skill-name references.

- Task tracker mandate: BEFORE executing any workflow or skill step, create/update task tracking for all steps and keep it synchronized as progress changes.

- User-question prompts mean to ask the user directly in Codex.

- Ignore Claude-specific mode-switch instructions when they appear.

- Strict execution contract: when a user explicitly invokes a skill, execute that skill protocol as written.

- Subagent authorization: when a skill is user-invoked or AI-detected and its protocol requires subagents, that skill activation authorizes use of the required spawn_agent subagent(s) for that task.

- Do not skip, reorder, or merge protocol steps unless the user explicitly approves the deviation first.

- For workflow skills, execute each listed child-skill step explicitly and report step-by-step evidence.

- If a required step/tool cannot run in this environment, stop and ask the user before adapting.

Codex Project-Reference Loading (No Hooks)

Codex does not receive Claude hook-based doc injection. When coding, planning, debugging, testing, or reviewing, open project docs explicitly using this routing.

Always read:

• docs/project-config.json (project-specific paths, commands, modules, and workflow/test settings)
• docs/project-reference/docs-index-reference.md (routes to the full docs/project-reference/* catalog)
• docs/project-reference/lessons.md (always-on guardrails and anti-patterns)

Situation-based docs:

• Backend/CQRS/API/domain/entity changes: backend-patterns-reference.md, domain-entities-reference.md, project-structure-reference.md
• Frontend/UI/styling/design-system: frontend-patterns-reference.md, scss-styling-guide.md, design-system/README.md
• Spec/test-case planning or TC mapping: feature-docs-reference.md
• Integration test implementation/review: integration-test-reference.md
• E2E test implementation/review: e2e-test-reference.md
• Code review/audit work: code-review-rules.md plus domain docs above based on changed files

Do not read all docs blindly. Start from docs-index-reference.md, then open only relevant files for the task.

Quick Summary

Goal: Analyze npm package dependencies, research latest versions and breaking changes, and generate a phased upgrade plan.

Workflow:

1. Inventory — Discover all package.json files, catalog dependencies and usage 2. Web Research — Batch-research latest versions, breaking changes, migration guides (groups of 10) 3. Risk Assessment — Categorize risk (Critical/High/Medium/Low), build dependency upgrade order 4. Report — Generate comprehensive upgrade report with phased migration plan 5. Approval Gate — Present report for user confirmation before any action

Key Rules:

• Must read anti-hallucination protocols before executing
• Research only from official sources (npm, GitHub, official docs)
• Declare confidence level; if < 90%, request user verification

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Frontend Package Upgrade Analysis & Planning

You are to operate as an expert frontend package management specialist, npm ecosystem analyst, and software architecture expert to analyze package.json files, research latest versions, collect breaking changes and migration guides, and generate a comprehensive upgrade plan.

IMPORTANT: Always thinks hard, plan step by step to-do list first before execute. Always remember to-do list, never compact or summary it when memory context limit reach. Always preserve and carry your to-do list through every operation.

PHASE 1: PACKAGE INVENTORY & CURRENT STATE ANALYSIS

Build package inventory in .ai/workspace/analysis/frontend-package-upgrade-analysis.md.

PHASE 1A: INITIALIZATION AND PACKAGE DISCOVERY

Initialize analysis file with:

• ## Metadata - Original prompt and task description
• ## Progress - Track phase, items processed, total items
• ## Package Inventory - All package.json files and dependencies
• ## Version Research Results - Latest versions and changelogs
• ## Breaking Changes Analysis - Breaking changes catalog
• ## Migration Complexity Assessment - Risk levels and effort estimates
• ## Upgrade Strategy - Phased migration plan

Find all package.json files:

src/{ExampleAppWeb}/package.json
src/{ExampleAppWeb}/apps/*/package.json
src/{ExampleAppWeb}/libs/*/package.json

For each package.json, document:

• Project Name & Location
• Framework Version
• Dependencies (categorized: Framework, UI, Build Tools, Testing, Utilities)
• DevDependencies

Create Master Package List consolidating all unique packages.

PHASE 1B: PACKAGE USAGE ANALYSIS

For each unique package, analyze codebase usage:

• Projects Using: Which projects depend on this
• Import Count: Number of files importing
• Key Usage Areas: Where primarily used
• Configuration Files: Config files for this package
• Upgrade Risk Level: Low/Medium/High/Critical based on usage breadth

---

PHASE 2: WEB RESEARCH & VERSION DISCOVERY

IMPORTANT: BATCH INTO GROUPS OF 10

For EACH package in Master Package List:

Latest Version Discovery

• Search: "[package-name] npm latest version"
• Check: https://www.npmjs.com/package/[package-name]
• Extract: Latest stable version, release date, downloads

Breaking Changes Research

• Search: "[package-name] migration guide [old-version] to [new-version]"
• Search: "[package-name] v[X] breaking changes"
• Search: "[package-name] changelog"
• GitHub: Check CHANGELOG.md, releases

Ecosystem Compatibility

• Angular version compatibility
• Check peerDependencies
• Cross-package dependencies

Document:

• Current vs. Latest versions
• Version gap (major/minor/patch versions behind)
• Breaking changes with migration steps
• Deprecation warnings
• Peer dependency changes

---

PHASE 3: RISK ASSESSMENT & PRIORITIZATION

Risk Categories

• Critical Risk: 5+ major versions behind, framework packages, 50+ breaking changes
• High Risk: 3-4 major versions, state management, 20-30 breaking changes
• Medium Risk: 1-2 major versions, some breaking changes
• Low Risk: Patch/minor updates, backward compatible

Dependency Graph (Upgrade Order)

1. Foundation packages (Node.js, TypeScript) 2. Framework packages (Angular Core, CLI) 3. Framework extensions (Material, RxJS) 4. Third-party libraries 5. Dev tools last

---

PHASE 4: COMPREHENSIVE REPORT GENERATION

Generate report at ai_package_upgrade_reports/[YYYY-MM-DD]-frontend-package-upgrade-report.md:

Report Structure

1. Executive Summary 2. Package Inventory by Project 3. Version Gap Analysis 4. Breaking Changes Catalog 5. Migration Complexity Assessment 6. Ecosystem Compatibility Analysis 7. Recommended Upgrade Strategy (Phased Migration Plan) 8. Detailed Migration Guides 9. Testing Strategy 10. Rollback Plan 11. Timeline & Resource Estimation 12. Appendices

---

PHASE 5: APPROVAL GATE

CRITICAL: Present comprehensive package upgrade report for explicit approval. DO NOT proceed without it.

---

PHASE 6: CONFIDENCE DECLARATION

Before marking complete, provide:

Solution Confidence Assessment

Overall Confidence: [High 90-100% / Medium 70-89% / Low <70%]

Evidence Summary:

• All package.json files discovered: [count]
• Web research completed: [X/Y packages]
• Breaking changes documented: [count]
• Official sources used: npm, GitHub, official docs

Assumptions Made: [List or "None"]

User Confirmation Needed:

• IF confidence < 90%: "Please verify [specific packages] before proceeding"
• IF confidence >= 90%: "Analysis is comprehensive, ready for migration"

---

Package Upgrade Guidelines

• Comprehensive Discovery: Find ALL package.json files
• Web Research Accuracy: Use official sources only (npm, GitHub, official docs)
• Breaking Changes Focus: Prioritize identifying breaking changes requiring code changes
• Risk Assessment: Evaluate complexity based on breaking changes, usage breadth, dependencies
• Practical Planning: Create actionable phased plan with realistic effort estimates
• Evidence-Based Decisions: Base ALL recommendations on actual research with sources cited
• Confidence Declaration: Declare confidence level; if < 90%, request user confirmation
• Batch Processing: Research packages in batches of 10

[IMPORTANT] Use task tracking to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

<!-- SYNC:source-test-drift-check -->

Source/test drift check. For coding, fix, debug, investigation, test, or review work: when source behavior changes, inspect affected unit/integration/E2E tests and decide from evidence whether tests should change to match intended behavior or the source change is an unintended bug to fix. Do not write tests for migration code; schema/data migrations are one-time execution paths, not core application logic.

<!-- /SYNC:source-test-drift-check -->

<!-- SYNC:ai-mistake-prevention -->

AI Mistake Prevention — Failure modes to avoid on every task:

>

Check downstream references before deleting. Deleting components causes documentation and code staleness cascades. Map all referencing files before removal.

Verify AI-generated content against actual code. AI hallucinates APIs, class names, and method signatures. Always grep to confirm existence before documenting or referencing.

Trace full dependency chain after edits. Changing a definition misses downstream variables and consumers derived from it. Always trace the full chain.

Trace ALL code paths when verifying correctness. Confirming code exists is not confirming it executes. Always trace early exits, error branches, and conditional skips — not just happy path.

When debugging, ask "whose responsibility?" before fixing. Trace whether bug is in caller (wrong data) or callee (wrong handling). Fix at responsible layer — never patch symptom site.

Assume existing values are intentional — ask WHY before changing. Before changing any constant, limit, flag, or pattern: read comments, check git blame, examine surrounding code.

Verify ALL affected outputs, not just the first. Changes touching multiple stacks require verifying EVERY output. One green check is not all green checks.

Holistic-first debugging — resist nearest-attention trap. When investigating any failure, list EVERY precondition first (config, env vars, DB names, endpoints, DI registrations, data preconditions), then verify each against evidence before forming any code-layer hypothesis.

Surgical changes — apply the diff test. Bug fix: every changed line must trace directly to the bug. Don't restyle or improve adjacent code. Enhancement task: implement improvements AND announce them explicitly.

Surface ambiguity before coding — don't pick silently. If request has multiple interpretations, present each with effort estimate and ask. Never assume all-records, file-based, or more complex path.

<!-- /SYNC:ai-mistake-prevention -->

<!-- SYNC:evidence-based-reasoning -->

Evidence-Based Reasoning — Speculation is FORBIDDEN. Every claim needs proof.

>

1. Cite file:line, grep results, or framework docs for EVERY claim

2. Declare confidence: >80% act freely, 60-80% verify first, <60% DO NOT recommend

3. Cross-service validation required for architectural changes

4. "I don't have enough evidence" is valid and expected output

>

BLOCKED until: - [ ] Evidence file path (file:line) - [ ] Grep search performed - [ ] 3+ similar patterns found - [ ] Confidence level stated

>

Forbidden without proof: "obviously", "I think", "should be", "probably", "this is because"

If incomplete → output: "Insufficient evidence. Verified: [...]. Not verified: [...]."

<!-- SYNC:critical-thinking-mindset -->

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act.

Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

<!-- CODEX:SYNC-PROMPT-PROTOCOLS:START -->

Hookless Prompt Protocol Mirror (Auto-Synced)

Source: .claude/hooks/lib/prompt-injections.cjs + .claude/.ck.json

[WORKFLOW-EXECUTION-PROTOCOL] [BLOCKING] Workflow Execution Protocol — MANDATORY IMPORTANT MUST CRITICAL. Do not skip for any reason.

Generic portability boundary: Reusable skills and protocol text stay project-neutral; project-specific conventions are discovered from docs/project-config.json and docs/project-reference/. Apply shared AI-SDD from shared/sdd-artifact-contract.md. Read docs/project-config.json and docs/project-reference/docs-index-reference.md, then open the project reference docs named there. Any supported AI tool may execute when this shared context and local docs are available.

1. DETECT: Match prompt against workflow catalog 2. ANALYZE: Find best-match workflow AND evaluate if a custom step combination would fit better 3. ASK (REQUIRED FORMAT): Use a direct user question with this structure unless the user explicitly invoked a workflow/skill and the local protocol treats explicit invocation as confirmation:

• Question: "Which workflow do you want to activate?"
• Option 1: "Activate [BestMatch Workflow] (Recommended)"
• Option 2: "Activate custom workflow: [step1 → step2 → ...]" (include one-line rationale)

4. ACTIVATE (if confirmed): Call $workflow-start <workflowId> for standard; sequence custom steps manually 5. CREATE TASKS: task tracking for ALL workflow steps 6. EXECUTE: Follow each step in sequence [CRITICAL-THINKING-MINDSET] Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination principle: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination. AI Attention principle (Primacy-Recency): Put the 3 most critical rules at both top and bottom of long prompts/protocols so instruction adherence survives long context windows. Goal-driven execution: Define success criteria first, loop until verified, and stop only when observable checks pass. Tests verify intent: Tests must protect business rules/invariants and fail when the protected intent breaks, not only mirror current behavior.

[LESSON-LEARNED-REMINDER] [BLOCKING] Task Planning & Continuous Improvement — MANDATORY. Do not skip.

Break work into small tasks (task tracking) before starting. Add final task: "Analyze AI mistakes & lessons learned".

Extract lessons — ROOT CAUSE ONLY, not symptom fixes:

1. Name the FAILURE MODE (reasoning/assumption failure), not symptom — "assumed API existed without reading source" not "used wrong enum value". 2. Generality test: does this failure mode apply to ≥3 contexts/codebases? If not, abstract one level up. 3. Write as a universal rule — strip project-specific names/paths/classes. Useful on any codebase. 4. Consolidate: multiple mistakes sharing one failure mode → ONE lesson. 5. Recurrence gate: "Would this recur in future session WITHOUT this reminder?" — No → skip $learn. 6. Auto-fix gate: "Could $code-review/$code-simplifier/$security/$lint catch this?" — Yes → improve review skill instead. 7. BOTH gates pass → ask user to run $learn. [TASK-PLANNING] [MANDATORY] BEFORE executing any workflow or skill step, create/update task tracking for all planned steps, then keep it synchronized as each step starts/completes.
