Draw, redraw and review TikZ figures for the Book (The Harbor, the Person, and the Economy) to the v2 figure language in figures/pd-figure-language.tex: a three-voice type ladder, hue-as-meaning concept colours, a 1 : 1.8 : 3.2 weight ladder, a surface…
[What it does] [When to use — be slightly pushy]. NOT for [explicit exclusions].
Decide page by page whether art improves comprehension.
Attack technical claims with counterexamples, not authors.
Generate falsifiable alternatives and discriminating experiments.
Reconcile definitions and evidence states across all retellings.
Complete source attribution, bibliography and analytical index.
Test a capable newcomer's intended reading path.
Trace equivalent claims across disciplines and terminology.
Independently solve exercises and reconcile answer keys.
Design semantically faithful Swiss-modern figures and blue-ink objects.
Make prerequisites and first-use concepts available before they do work.
Review multi-agent coordination scholarship and disciplinary boundaries.
Audit comparators, uncertainty, dependence and empirical scope.
Make exposition shorter and clearer without deleting assumptions.
Find simpler implementations and honest operational contracts.
Independently verify final-page typography, figures and accessibility.
Audit quantifiers, assumptions and theorem-to-prose scope.
Reproduce named checks in pinned isolated environments.
Verify exact source identity and support for attributed claims.
Coordinate retained evidence, dependencies and serialized integration.
Publish branches, pull requests, comments, review replies, readiness changes, reviewer requests, and merge-queue actions through Port Daddy's attributable GitHub App actuator without exposing or falling back to an operator's personal GitHub credentials. Use…
Revise the Harbor Book so prose, drawings, and marginalia explain the same argument without unpublished development-document dependencies. Use for chapter additions, substantive rewrites, caption editing, visual exposition, and eliminating internal ADR…
Architecture-level decisions for putting a CDN in front of a web app's static assets, API responses, and file/media delivery: provider selection (hyperscaler vs. specialist $/GB), signed-URL / tokenized access for gating private content at the edge, cache…
Runs an iterative, conversational product-discovery process with a founder/stakeholder: structured interview, live low-fi wireframing, a linked feature/page node-graph built up as you go, a founder-confirmed lock-in checkpoint, then a generated PRD, a…
Architects the encryption, codec/transport, and premium-feature layer of a group video-calling product, on top of an already-chosen SFU topology. Covers E2EE patterns (Zoom leader-fan-out, Signal pairwise-fan-out, MLS/TreeKEM as in Discord's DAVE, Telegram's…
Rewrite, extend, and visually normalize The Harbor, the Person, and the Economy as one assembled textbook. Use for chapter rewrites, new examples, theorem exposition, figure redesign, marginalia, captions, reader pacing, and Book-wide visual QA. This is the…
Chartwork for the Harbor library: choosing the diagram kind that fits an idea and drawing it in TikZ to the house style, with mechanical figure QA. Use when drafting, redesigning, auditing or QA-ing any figure in the chapters or research papers. NOT for…
Authoritative style guide, design doctrine, and automated QA system for all figures, plots, and diagrams in The Harbor, the Person, and the Economy. Use when proposing, drafting, restyling, or auditing TikZ figures, pgfplots charts, protocol sequence…
Compendium of the Harbor coordination program's executed results R1–R17 — information floor, split-digest theorem, derived regret head, digest-zoom frontier, hypervisor-as-supervisory-control, sheaf equivocation verdict (with the consistency-radius theorem),…
Designs UGC video pipelines from upload through adaptive-bitrate transcode, HLS/DASH packaging, and CDN delivery — including managed-platform selection (Cloudflare Stream, Mux, BunnyCDN Stream) vs. self-hosted FFmpeg + object storage + CDN, pre-publish…
Designs ML/classifier-based automated signal detection for platform trust & safety -- combining hash-matching and probabilistic ML scoring to flag spam, abusive behavior, and policy-violating content for human review or automated action. Use when integrating…
Designs the human side of content moderation operations: severity-tiered report queues, automatic context assembly for reviewers, isolation of child-safety/imminent-harm content into a restricted queue, and admin-tool choice…
Chooses and designs the backend data-model and storage architecture for chat/messaging features (1:1 DMs and group chat) — Postgres vs. wide-column stores vs. managed realtime backends, fan-out-on-write vs. fan-out-on-read delivery, ephemeral/TTL chat…
Architects real-time "who's nearby" map features (Sniffies/Grindr/Zenly-style) -- geospatial index selection (PostGIS vs geohash vs H3 vs Redis GEO), privacy-preserving location fuzzing, and live WebSocket position-update delivery with client/server…
Decides WHETHER a scaling database-backed app actually needs a cache layer (typically Redis) and WHERE to put it — diagnosing query/index/N+1 problems first, then choosing cache-aside vs write-through and TTL vs event-based invalidation at the right…
How the best math/CS textbooks (Halmos, Axler, SICP, Knuth, Feynman, Sipser, CLRS, MacKay, Pólya, Lakatos, Hersh) open a chapter, place worked examples and exercises, and state honest boundaries — applied to the Harbor Book's chapters. Use when drafting or…
Applies Edward Tufte's evidence-design doctrine — data-ink ratio, graphical integrity and the Lie Factor, small multiples, sparklines, layering and micro/macro readings, the fundamental principles of analytical design, and sentences-over-bullets — to choose…
Architects ad-hoc WebRTC video/audio chat for web and mobile apps — 1:1 calls, group calls, and shareable "party links" that let anyone with the link join a live room without a prior account relationship. Covers topology choice (mesh vs SFU vs MCU),…
Diagnoses, selects, and audits the semantic form of technical-paper figures before TikZ implementation. Use for any figure in the seven Port Daddy whitepapers, especially when the current result is generic boxes and arrows, prose in shapes, an ornamental…
