Career-Ops is an open-source job search automation pipeline built on top of Claude Code. Created by indie developer santifer after getting laid off, it scans 45+ company career portals in parallel, scores each listing A–F across 10 weighted dimensions (tech stack match, growth stage, remote policy, etc.), and auto-generates tailored ATS-optimized PDF resumes for every application — all from a terminal dashboard. The creator used it personally to evaluate over 740 job listings, generate 100+ personalized CVs, and eventually land a Head of Applied AI role. The whole pipeline runs locally, with no SaaS fees or data sharing — just your API key and a YAML config for your preferences and skills. What makes Career-Ops stand out is the combination of deterministic scoring with AI-generated personalization. The scoring rubric is user-configurable, so you can weight "remote-first" heavily or prioritize Series B startups. Released April 4, 2026, it hit 21k GitHub stars within four days and is trending on Product Hunt today — a rare indie tool that solves a genuinely painful problem.

Terrarium
Evals that actually simulate real deployment — stateful, multi-turn, alive

Terrarium is a multi-turn evaluation and optimization engine for LLM agents built by evolvent-ai. Unlike static benchmark suites that measure agents against fixed input-output pairs, Terrarium creates persistent, stateful "living environments" — simulated deployment contexts where agents operate over extended sessions, accumulate state, use tools, and interact with simulated external systems. You evaluate agents the way you'd test a car: by driving it, not by measuring its doors. The system supports configurable environment complexity, including simulated databases, APIs, file systems, and user personas. Agents are scored not just on final outputs but on trajectory quality — how efficiently they reached the answer, how often they hallucinated intermediate steps, and how well they recovered from dead ends. The engine also supports continuous optimization loops where poor-performing trajectories trigger automatic prompt refinement. With 17 stars and created April 14, Terrarium is extremely new. But it's addressing a genuine gap: the disconnect between how agents perform on static benchmarks versus how they behave in production. As enterprise AI deployments scale, the need for realistic pre-production evaluation is becoming critical.
Reviewer scorecard
“This is exactly what Claude Code was made for — a high-signal agentic loop that replaces hours of manual work with a config file and a run command. The fact the creator used it to actually land a job makes it more credible than 90% of 'AI-powered' job tools. Fork it, tweak the scoring weights, ship your apps.”
“Static evals are lying to us constantly — agents that ace benchmarks fall apart in production because benchmarks don't have state, side effects, or accumulated context. Terrarium's living environments model is the right approach to catching real failure modes before deployment.”
“Generating 100+ tailored resumes sounds impressive until you realize most ATS systems now flag mass-application patterns. If every laid-off dev runs this, recruiters will start seeing the same Claude-generated phrasing everywhere and discount it. Also, scraping 45 career portals at scale risks IP bans and ToS violations.”
“Building a realistic simulation of your production environment is often harder than just running the agent in staging. The value proposition assumes your eval environment is meaningfully closer to production than your existing test suite — which is a big assumption for complex deployments.”
“The meta-narrative here is striking: AI displaced this developer, and then AI tools helped them land a better job. Career-Ops points toward a near future where your job search agent runs 24/7, continuously matching your evolving skill profile against a live stream of openings. The labor market is about to get very weird.”
“The eval-optimize loop is the missing piece in most AI agent development workflows. Tools that can automatically identify weak trajectories and suggest improvements will become as fundamental as unit tests. Terrarium is early, but the category is inevitable.”
“As someone who's spent days customizing resumes for specific roles, the idea of a local pipeline that generates polished PDFs tailored to each JD is genuinely appealing. The terminal dashboard aesthetic is very much dev-only right now, but if someone wraps a nice UI around this it becomes a serious Teal alternative.”
“This is deeply technical infrastructure that won't affect my daily workflow. The people who need this know they need it — but for most creators building with AI tools, static evals are already more than they use.”
