From 8b58f014e798341133ae074f74085ee15e286170 Mon Sep 17 00:00:00 2001 From: Florian BRUNIAUX Date: Fri, 30 Jan 2026 12:32:38 +0100 Subject: [PATCH] docs: add Addy Osmani 80% problem to Practitioner Insights Add Addy Osmani (Google Chrome Team) article "The 80% Problem in Agentic Coding" to AI Ecosystem Practitioner Insights section. Changes: - guide/ai-ecosystem.md: Add 32-line entry after Steinberger (~line 2024) * "80% problem" framework and comprehension debt concept * Three new failure modes (overengineering, assumption propagation, sycophantic) * Productivity paradox data (+98% PRs, +91% review time) * Alignment table mapping to existing guide sections * Transparent note: "secondary synthesis, primary sources documented" - machine-readable/reference.yaml: Add 4 new references * practitioner_addy_osmani, practitioner_osmani_source * eighty_percent_problem, comprehension_debt_secondary - docs/resource-evaluations/024-addy-osmani-80-percent-problem.md: Complete evaluation * Score: 3/5 (Pertinent) - downgraded from initial 4/5 after technical-writer challenge * Minimal integration (32 lines vs rejected 250 lines) * Fact-check: 6 stats verified, 1 Stack Overflow stat incorrect * Rationale: 90% overlap with existing content (Vibe Coding Trap, Trust Calibration) - CHANGELOG.md: Document addition in v3.19.0 Decision: Minimal integration approach chosen to avoid duplication while recognizing value of synthesis from respected author. Article aggregates existing research already cited in guide with primary sources.
