npm Email Companion

npm controls the native "Successfully published" email template, so the email itself stays short. Treat this generated artifact as the full release-note companion for that email: it carries the Changeset summaries, CHANGELOG entry, publish workflow, npm tarball, and shasum when available.

Full Changeset Release Notes

Minor Changes

.changeset/dashboard-insights-tab.md

Add Insights tab to dashboard with interactive Chart.js charts (feedback trend, lessons generated, gate effectiveness), clickable pipeline visualization, and data consistency fix across all stat paths.

.changeset/demo-voiceover-and-linkedin-automation.md

Add ElevenLabs-based demo voiceover automation (scripts/generate-demo-voiceover.js) that extracts narration from the canonical demo video script and synthesizes an mp3 via the ElevenLabs TTS API. Promote the landing page demo video out of the collapsed <details> into a visible inline hero embed, add a 90-second demo section to the top of README.md, and rewrite the Show HN launch draft around the token-cost mission. Schedule reply-monitor.yml daily at 13:00 UTC with LinkedIn environment passthrough, and ship two LinkedIn ops docs: a 2-minute daily manual-check runbook and a fully-drafted LinkedIn Community Management API application package.

.changeset/token-cost-mission.md

Reposition ThumbGate around a single sharp mission: stop your AI from making the same mistake twice. Repeated AI mistakes cost real money in tokens — one thumbs-down captures the lesson and ThumbGate blocks that exact pattern on every future call, across every agent.

• New hero copy everywhere — plain-English, pain-point-in-one-sentence, no buzzword cadence. Applied to landing page, README, meta/OG tags, JSON-LD, package.json, plugin.json, and config/github-about.json.
• Live "💸 Tokens Saved" counter on the dashboard. New scripts/token-savings.js helper (21 tests, Sonnet-blended default) turns blocked-gate + bot-deflection counts into a live token + dollar estimate. Swap in your own model mix to honestly reflect your Anthropic / OpenAI bill.
• New ClawHub / OpenClaw distribution skill — dist/clawhub-skill/SKILL.md — ready for npm run clawhub:publish once authenticated. Expands the distribution surface to the OpenClaw skill marketplace alongside the Claude Extension, Codex plugin, npm, and MCP marketplaces.
• SEO blog post docs/marketing/blog-token-cost-mission.md ranking on "save Claude tokens" / "reduce LLM cost" / "AI agent token waste."
• Pre-validated social pack docs/marketing/token-cost-mission-social-pack.md (X/Threads/LinkedIn/HN/Reddit/TikTok) under every platform's char limit.

Patch Changes

.changeset/chatgpt-actions-openapi-yaml.md

Expose the ChatGPT Actions OpenAPI YAML import before bearer auth and document the GPT Builder bearer key setup.

.changeset/checkout-bot-deflection.md

Deflect checkout crawlers and link-preview bots before creating Stripe sessions so revenue telemetry reflects real buyer intent.

.changeset/claude-extension-hero-cta.md

Add prominent "Install Claude Extension →" CTA to the landing page hero section, matching the existing Codex plugin link. Links to the .mcpb bundle download with PostHog tracking.

.changeset/codex-statusline-target.md

Wire the full Codex hook bundle during init and add the Codex status line target to the generated local config.

.changeset/conversion-overhaul-v2.md

Landing page conversion overhaul: restructure visual hierarchy for conversion

• Hero: single dominant CTA (install command + Install Free CLI), secondary CTAs grouped and visually demoted
• Terminal demo: moved immediately after hero to show the product before any explanation
• Trust bar: added above-the-fold honest social proof (MIT, GitHub stars, local-first, 6 integrations)
• Hero headline: rewritten for clarity ("Stop expensive AI agent mistakes before they happen")
• Nav: simplified to 4 visible links (How It Works, Pricing, FAQ, GitHub) + Install Free CTA
• Enterprise intake form: collapsed behind a details/summary toggle to reduce page overwhelm
• Newsletter section: simplified headline, removed internal jargon ("Buyer Follow-Up" → "Stay Updated")
• Final CTA: simplified to 2 primary actions, secondary CTAs visually demoted
• CSS: added conversion hierarchy styles to reduce visual weight of secondary sections
• Pro pricing card: added email capture input (pro-email) for 7-day trial flow
• All 36 landing page tests pass

.changeset/conversion-postinstall-v2.md

Rewrite postinstall banner to drive first-dollar conversion. Lead with concrete token-waste pain point, add tracked /go/pro click-through (UTM: source=npm, medium=postinstall, campaign=first_dollar) alongside direct Stripe link, clean up ragged box formatting. Every npm install sees this banner — making it the highest-leverage conversion touchpoint.

.changeset/decision-trace.md

Add decision-trace module for full gate evaluation observability. Logs passes, blocks, and near-misses (constraints that almost matched). Includes session trace summaries showing safety posture at a glance — inspired by Ethan Mollick's observation that operators need to see agent thinking traces.

.changeset/fix-stale-hooks.md

Fix wire-hooks to clean stale project-level Claude Code hooks referencing missing files. Previously only cleaned user-level settings, leaving broken hooks in .claude/settings.json that caused "UserPromptSubmit hook error".

.changeset/fix-static-asset-401.md

Fix: serve public static assets (/assets/*, /favicon.ico, /thumbgate-logo.png, /og.png, /apple-touch-icon.png) without requiring an API key. Before this change the landing page rendered but every image, video, and icon fell through to the /v1/* API-key guard and returned 401, leaving visitors with an empty video player and broken poster images. Adds path-traversal-safe asset routing with correct MIME types, Cache-Control: public, max-age=86400, immutable, and HEAD-request support. Covered by tests/public-static-assets.test.js.

.changeset/gate-coherence.md

Add gate-coherence analyzer to detect pseudo-unification across enforcement layers. Runs 20 probes across spec-gate and gate-config layers, detects contradictions (one blocks, another allows), coverage gaps (dangerous input passes all layers), and false positives. Reports coherence score and grade (unified/divergent/over-blocking). Inspired by entropy-probing research on pseudo-unification in multimodal models.

.changeset/gate-eval.md

Add gate-eval module for systematic evaluation of gate effectiveness. Operators define eval suites (expected block/pass outcomes), run them against specs, get precision/recall/F1 metrics, compare spec versions A/B, and track effectiveness trends over time. Ships with 16-case agent-safety eval suite. Inspired by Anthropic's prompt evaluation framework.

.changeset/instagram-publishing-wire-up.md

Fix Instagram publishing end-to-end. post-video.js now uses the Zernio presign upload flow + shared publishPost, matching the { url, key, size, contentType, type } media-item shape Instagram requires (legacy /media multipart + minimal { url, type } payload was silently rejected). Added instagram dispatcher to post-everywhere.js (previously a silent no-op). Added daily instagram-autopilot.yml workflow that posts a ThumbGate card via publish-instagram-thumbgate.js.

.changeset/landing-page-claude-first-overhaul.md

feat: Claude-first landing page overhaul

Restructures the entire landing page to prominently feature Claude plugin, Claude Extension, and Claude Code alongside (and above) the GPT promotion:

• Hero section: rewrites subtitle from GPT-first to agent-agnostic, adds "Install Claude Extension" as a primary amber CTA button
• New dedicated Claude Code section added before the ChatGPT GPT section
• Compatibility grid reordered: Claude Desktop Extension first, Claude Code Skill second, ChatGPT demoted to last
• First-Dollar Activation Path rewritten from GPT-centric to agent-agnostic install flow
• Proof bar reordered with Claude links first
• Final CTA adds Claude Extension button
• Nav bar adds Claude link and Claude Extension CTA
• GPT section renamed to "Also Available" to reduce GPT-first impression

.changeset/marketing-assets-readme-overhaul.md

Marketing assets and README overhaul: conversion-optimized README with architecture diagrams, SEO tutorial article, Manus AI skill, and technical architecture diagrams (MCP flow, feedback pipeline, agent integration).

.changeset/monetization-cta-autopilot.md

Wire Stripe pricing calls to action into the marketing autopilot and scheduled X revenue loop.

.changeset/monetization-paywall-fix.md

fix(monetization): enforce lifetime free-tier caps, reduce Team pricing to $49/seat

• Rate limiter switched from daily resets to lifetime caps (3 captures, 1 rule, recall blocked)
• Team plan reduced from $99 to $49/seat/month with new Stripe price ID
• Landing page rewritten with pain-first copy, hard limits visible, updated CTAs

.changeset/prompt-evaluation-positioning.md

Add prompt-evaluation positioning to the README and landing page so ThumbGate explains that prompt engineering is only the start, and proof lanes plus self-heal checks are how behavior gets measured and enforced.

.changeset/public-version-sync.md

Fix public landing page version synchronization so multiple release markers update in one pass.

.changeset/revenue-observability-truth.md

Harden revenue observability by preferring hosted billing-summary truth over local fallback when THUMBGATE_API_KEY is available, adding machine-readable Stripe live status diagnostics, and wiring the daily revenue loop to audit hosted revenue, Stripe, and Plausible checkout attribution with artifacts.

.changeset/sales-pipeline-first-dollar.md

Add a local sales pipeline ledger for first-dollar workflow hardening outbound, and update GTM targeting so direct outreach leads with the Workflow Hardening Sprint before self-serve Pro follow-up.

.changeset/sandbox-gate-scope.md

Add sandbox scope to spec-gate constraints for secure code execution environments. Adds 2 sandbox-specific constraints (no-sandbox-network, no-sandbox-fs-escape) to agent-safety spec. Also adds workflow-gate-checkpoint module for persisting gate state across long-running workflow restarts. Inspired by Vercel's Open Agents infrastructure.

.changeset/session-health-sensor.md

Add session health sensor and episodic session store for real-time and cross-session agent degradation detection. Tracks repeat errors, negative feedback density, stagnation, context amnesia, time-of-day risk, category risk, recurring errors, and feedback effectiveness trends.

.changeset/spec-gate.md

Add spec-gate module for proactive correctness enforcement. Operators define specs (constraints + invariants) upfront as JSON; gates enforce them from session start, not just from learned failures. Ships with agent-safety spec covering force-push, secrets, destructive ops, and test-before-commit invariants.

.changeset/thumbgate-only-scope.md

Enforce ThumbGate-only launch, GPT Actions, analytics, and outreach surfaces so legacy repository names cannot leak into active product guidance.

CHANGELOG.md Entry

1.5.1

Minor Changes

• Add Insights tab to the dashboard with interactive Chart.js charts:
  • Feedback Trend (30-day line chart): daily thumbs-up/down signals over time
  • Lessons Generated (bar + cumulative line): how many lessons were distilled each day
  • Gate Effectiveness (stacked bar): 14-day audit of blocked/warned/allowed actions
  • Feedback → Lesson Pipeline: clickable flow showing how signals convert to lessons, gates, and blocked actions with conversion rates
  • How ThumbGate Learns: 4-step visual explainer (React → Distill → Promote → Block)
• New backend functions: computeFeedbackTimeSeries() (30-day daily up/down/lesson counts) and computeLessonPipeline() (stage-by-stage conversion metrics)
• Dashboard API (/v1/dashboard) now returns feedbackTimeSeries and lessonPipeline fields

Verification Standard

• Publish only runs from main after version sync, tests, and runtime proof pass.
• The npm package is smoke-tested after publish by installing thumbgate@VERSION in a clean runtime.
• GitHub Release notes are generated from Changesets, not only GitHub auto-generated PR titles.
