LinguaRAG: First Production Deploy

Full pipeline from local environment setup to Render + Vercel production deployment

What I Did

• Local environment — set up PostgreSQL@17, Python venv, npm install, .env configuration
• German TTS — Web Speech API integration: click bold text in chat to hear pronunciation, with volume slider. Uses browser built-in speechSynthesis with de-DE locale at rate 0.85
• Render backend deploy — Docker-based FastAPI deployment on Render free tier (Singapore region). Created Render PostgreSQL and initialized schema.sql
• Vercel frontend deploy — Next.js frontend on Vercel, connected to Render backend via BACKEND_URL env var. Next.js API routes proxy all backend calls (simplifies CORS and cookie handling)
• Security upgrade — Next.js 15.1.4 → 15.5.12 to fix CVE-2025-66478 (was blocking Vercel deployment)

Key Decisions

• Railway → Render migration — Railway dropped their free tier; Render free tier has trade-offs (50s cold start, 90-day DB limit) but works for development stage
• Next.js API Route proxy pattern — browser → Vercel /api/chat → Render backend. Eliminates CORS configuration and simplifies cookie/auth token passing

Learnings

• Render web service names are globally unique — linguarag-backend was already taken but eventually resolved
• Claude Max subscription API credits are separate from Anthropic API credits — had to purchase $5 API credits separately for the backend

debate-plugin (17:44)

Implemented 5-layer AI quality system + renamed think-deep → debate v2 + designed and implemented multi-round tiki-taka debate engine

Done

• feat: designed and implemented 5-layer AI quality system
  • Layer 3 (Output Quality): added Claim Labeling rules to ~/.claude/CLAUDE.md ([FACT]/[ESTIMATE]/[OPINION]/[UNCERTAIN])
  • Layer 5 (Usage Quality): added Question Routing table to ~/.claude/CLAUDE.md (technical/values-based/prediction classification)
  • Layer 1 (Input Quality): created ~/.claude/context/ infrastructure (values.md, constraints.md, decision-log.md)
  • Layer 2 (Process Quality): implemented as debate plugin
  • Layer 4 (Validation Quality): implemented as decision-log.md template
• feat(debate): renamed think-deep → debate plugin (v2.0.0)
• feat(debate): implemented v2 multi-round debate engine — Mode 0 (quick verdict) / Mode 1 (autonomous debate) / Mode 2 (participatory debate)
• feat(debate): added automatic context detection — extracts decision topic from recent conversation even with just “debate” as input
• feat(debate): added Round N Behavior to 4 agents — position tracking ([MAINTAINED/PARTIALLY_CONCEDED/SHIFTED]), cross-rebuttal rules
• feat(debate): selectively adopted llm-council concepts — adopted cross-rebuttal, position tracking, convergence detection; did not adopt anonymization
• chore: created personalized context files in ~/.claude/context/ (values.md, constraints.md, decision-log.md)

Key Decisions

• debate vs separate re-verification tool: Layer 3 always-on claim labeling covers everyday answer reliability, debate Mode 0 covers focused re-verification → no need for a separate tool
• Anonymization not adopted: llm-council anonymization is for preventing multi-LLM prestige bias — in single Claude model, role names are needed for tiki-taka structure
• Claude Max = no additional API cost: Task() calls are included in subscription, no round limits needed

Next

• Test an actual decision with debate Mode 0 (e.g. tech stack choice, career decision)
• Record first real entry in decision-log.md
• Consider adding “verify” mode: shortcut to post-hoc verify a specific Claude answer via debate agents
• Strengthen Layer 1: actively use and update ~/.claude/context/ files

debate-plugin (20:06)

Renamed debate → prism-debate + added 2 new agents (Alternative, Pre-Mortem) + Worldview characterization + README v2 (Mermaid + How It Works)

Done

• feat(prism-debate): renamed debate → prism-debate (v3.0.0) — plugins/debate/ → plugins/prism-debate/, triggers prism/prism-debate//prism
• feat(prism-debate): created 2 new agents
  • agents/alternative.md — “The Inventor” (REFRAME): proposes 2-3 concrete alternatives outside the proposition, based on De Bono Green Hat
  • agents/pre-mortem.md — “The Oracle” (FUTURE FAILURE): assumes failure as a given and traces back, 5 Whys causal chain. Based on Gary Klein PreMortem
• feat(prism-debate): Worldview characterization for all agents (Moltbook insight)
  • Optimist → “The Builder” / Critic → “The Skeptic” / Pragmatist → “The Operator” / Synthesizer → “The Judge”
• feat(prism-debate): added Core/Extended agent selection logic to SKILL.md — Core 3 (Optimist+Critic+Pragmatist) / Extended 5 (+Alternative+Pre-Mortem)
• docs(prism-debate): full README v2 overhaul — 2 Mermaid diagrams, How It Works, Context Integration, Output Reference sections
• docs(prism-debate): full CLAUDE.md update (v3.0.0 architecture, agent table, validation checklist)

Key Decisions

• Name prism-debate: combines “prism” (purpose: multi-angle analysis) + “debate” (mechanism: cross-rebuttal) to convey both why and how
• De Bono Six Hats mapping: Yellow(Optimist) + Black(Critic) + White(Pragmatist) + Green(Alternative) + separate Oracle(Pre-Mortem)
• Moltbook insight: Worldview is more consistent and predictable than Stance (FOR/AGAINST) for characterizing agents
• Alternative added first: binary blind spot (A vs not-A) is the most universal blind spot → first extended agent
• Pre-Mortem differs from Critic: Critic identifies risks in forward direction, Pre-Mortem assumes failure and traces back → justifies separate agent
• 2-tier structure: Core 3 (always) + Extended 2 (optional) — balances minimizing complexity vs analysis depth

Next

• Test an actual decision with prism-debate Mode 0 Core (e.g. tech stack, career decision)
• Test prism-debate Extended mode — confirm Alternative + Pre-Mortem work in practice
• Record first real entry in decision-log.md
• Design future agents: Gut Check (Red Hat / intuition & values) + Red Team (adversarial attack simulation)
• Strengthen Layer 1: actively use ~/.claude/context/ files during actual debates

competitive-agents (20:40)

Connected planning-interview outputs as competitive-agents input + removed dev-log.md + removed frontmatter version field

Done

• feat(competitive-agents): added “Use planning-interview outputs” option to Step 1 — takes directory path and reads prd.md, user-journey-map.md, tech-spec.md, wireframe-spec.md to aggregate as mission context
• feat(competitive-agents): added planning-interview docs copy logic to Step 11.5 — when planning_docs_path is set, copies files as-is to final/docs/
• chore(competitive-agents): removed dev-log.md generation from Step 11.5 — low practical value as an empty template
• fix(competitive-agents): removed version field from SKILL.md frontmatter — unsupported attribute in skill files (resolves IDE warnings)
• docs(competitive-agents): updated Step 12 completion summary and Quick Reference output tree to reflect planning-interview docs

Key Decisions

• planning-interview → competitive-agents connection: planning-interview generates 4 docs (prd/user-journey/tech-spec/wireframe), using them directly as mission context is the natural workflow
• dev-log.md removed: empty templates have low generation value and users are better off creating their own. decisions.md (ADR) alone is sufficient for project history
• version field removed: confirmed as unsupported attribute in Claude Code skill files → removed entirely

Next

• Verify Step 11.5 behavior after competitive-agents run (select generate_docs = Yes)
  • Confirm decisions.md ADR quality — test that it extracts correctly from judge report
  • Confirm spec.md copy behavior when spec file is provided
• Test full planning-interview → competitive-agents flow — generate 4 docs with planning-interview → select “Use planning-interview outputs” in competitive-agents → verify final/docs/
