Oliver Kriska @quatermain.bsky.social · 21/05/2026Before v2.6.0, the /phx:plan skill in my Claude Code plugin had a 0% trigger recall. Send "build a chat feature" to Haiku. It would never route to /phx:plan. The skill was good. The description was unfindable. 120
Oliver Kriska @quatermain.bsky.social · 21/05/2026I never write notes. My tools do. scribe reads my git commits, my Claude Code + Codex sessions, the links I text myself — and writes a wiki my next agent session queries. 6,977 docs in 4.5 months. Zero typed by hand. getscribe.dev #ClaudeCode #AI 120
Oliver Kriska @quatermain.bsky.social · 20/05/2026v2.10.1 → v2.10.3 of the Elixir/Phoenix plugin for Claude Code. Three patch releases, one theme: be a better citizen — global-install safe, slash commands reliable, hooks aligned with latest CC. 28 files | +635/-90 github.com/oliver-kriska/claude-elixir-phoenix #ElixirLang #ClaudeCode 150
Oliver Kriska @quatermain.bsky.social · 19/05/2026v2.10.0 of the Elixir/Phoenix plugin for Claude Code ships a second plugin alongside it: catchup — framework-agnostic, return-from-absence briefing for async teams. One /catchup, one prioritized brief. No firehose. phxagents.dev/install #ClaudeCode #DevTools 210
Oliver Kriska @quatermain.bsky.social · 17/05/2026laude-elixir-phoenix at 4 months in. 41 skills · 20 specialist agents · 22 Iron Laws · 100 reference docs · 18 hooks. ~28,000 lines. Everything I have learned shipping production Phoenix apps, encoded as machine-readable rules. github.com/oliver-kriska/claude-elixir-phoenix 272
Oliver Kriska @quatermain.bsky.social · 15/05/2026$8,523 of Claude Code over ~4.5 months. 11.9B tokens. 11.4B of them — 96% — are cache reads. That ratio is the whole story. The bill stays low not because the work is small, but because the harness reuses context instead of paying for it twice. 100
Oliver Kriska @quatermain.bsky.social · 14/05/20267 specialist agents reviewing one PR in parallel. 37 files, +296 / −123. A real rewrite, not a toy diff. ~315k tokens, ~2 minutes wall time. Sequential would be ~11 minutes 130
Oliver Kriska @quatermain.bsky.social · 14/05/202611,000 PRs. 5 active developers. 26 contributors total. 5 years. Not because we are unusually fast. Because the pipeline is set up so that "is this safe to merge" is a 2-minute question, not a 2-hour one. Pipeline beats individual velocity, every quarter, forever. #SoftwareEngineering 041
Oliver Kriska @quatermain.bsky.social · 12/05/2026METR, 2025: experienced devs using AI were 19% slower. They believed they were 24% faster. The IDE got faster. The pipeline did not. The brain definitely did not. That gap is where most of the AI productivity debate is happening — and almost no one is naming it. #AIEngineering 100
Oliver Kriska @quatermain.bsky.social · 11/05/2026For the past 4 months I have been quietly building a pipeline: more than 4,000 markdown documents of research, session logs, Phoenix patterns, and what I have actually shipped — all indexed, searchable. That is the input. The output starts this week. 220

Oliver Kriska @quatermain.bsky.social · 04/12/2024Really good reading about technical details how LiveView works with main features. Partly I'm sad to see how features-full framework it is, now dev will not have to invent new approaches for their issues because LV+ Elixir/Erlang handle them. #myelixirstatus www.phoenixframework.org/blog/phoenix...phoenixframework.org Phoenix LiveView 1.0.0 is here! - Phoenix Blog LiveView 1.0 is out! 030

Oliver Kriska @quatermain.bsky.social · 27/11/2024Well, another blog post is coming. This time more Elixir than the last one about PostgreSQL. Not too much Elixir code but there will be public GitHub repo available. Hope it will help more people to fix some popular issues. #myelixirstatus 010

Oliver Kriska @quatermain.bsky.social · 05/11/2024"We can not use Elixir, because it's hard to find senior Elixir developers." Well, problem will be somewhere else.... 700 applications for senior position with US TZ overlap in 24hours. Screenshot from Elixir Slack. #myelixirstatus 010
Oliver Kriska @quatermain.bsky.social · 04/11/2024As you become more senior in your career, you’re not hired for some shiny happy opportunity, you’re hired to fix something. You’ll probably inherit mess (product, tech, org), but if you’re good—you don’t complain. It’s not your fault, but it is your problem. So get to work 💪 by clairevo 030
