Claudoscope is a free, open-source macOS menu bar app that gives Claude Code users a full session history browser, cost analytics, and search across all their coding sessions. It reads directly from local JSONL session files in ~/.claude/projects/ and works entirely offline — no telemetry, no data sent anywhere, fully MIT-licensed. The tool estimates costs from raw token counts against published API pricing, giving developers a clear picture of where their Claude Code spend is going across projects and sessions. It also automatically scans for leaked API keys and credentials in session content — effectively adding a passive security audit to every session review. Claudoscope fills a real gap: Claude Code's built-in /cost command only covers the current session. Claudoscope gives historical visibility and project-level analytics. It works with any Claude Code deployment including Enterprise API setups where cookie-based session trackers fail. Built and maintained by an indie developer, free forever.

Real-world agent skills for engineers — install via npm, not vibes

Skills is a curated library of AI agent prompts and workflows for real software engineering, created by TypeScript educator Matt Pocock. The project trended to 28,000 GitHub stars with its blunt tagline: "Agent skills for real engineers — not vibe coding." It's a deliberate pushback against chaos-first AI coding in favor of structured, methodical engineering. The library organizes into four categories: Planning & Design (to-prd for converting conversations into PRDs, grill-me for stress-testing plans), Development (tdd for test-driven AI assistance, triage-issue for bug investigation), Tooling & Setup (pre-commit hooks, git safety guards), and Writing & Knowledge (documentation utilities, Obsidian integration). Each skill installs with a single npx command — npx skills@latest add mattpocock/skills/tdd — and plugs into Claude agent setups. With 28,000 stars and 2,200 forks after trending on GitHub on April 27, 2026, Skills has clearly struck a nerve. It's as much a cultural statement as a product: AI coding tools should be used deliberately, with tests, with planning, and with guardrails. The TDD and triage-issue skills address real gaps in how current AI coding agents handle existing codebases rather than greenfield projects.
Reviewer scorecard
“As someone who runs Claude Code 8+ hours a day, this is immediately valuable. I had no idea which projects were burning through tokens until I installed it. The leaked credential detection is a bonus I didn't expect — it already caught a test API key I'd forgotten to rotate.”
“The tdd skill alone is worth the install. Watching a Claude agent plan tests before writing implementation is exactly how I want AI to assist me. Matt's framing of 'real engineering vs. vibe coding' is the right cultural correction for 2026.”
“This is fundamentally a log file reader with cost estimation math. Anthropic could ship this natively in Claude Code in a single PR and make Claudoscope obsolete overnight. The gap it fills is real, but the risk of deprecation-by-inclusion is very high for an indie-maintained tool.”
“These are sophisticated markdown prompts, not magic. If you're already a disciplined engineer, the skills add ceremony without much acceleration. The 28K stars partly reflect Matt's Twitter following — evaluate the actual skills before star-chasing.”
“The emergence of cost-tracking tools for AI coding sessions is a leading indicator of developer maturity. When developers start optimizing their AI spend like they optimize their AWS bill, we've crossed a real threshold. Claudoscope is primitive, but it's the first version of what becomes a full AI development economics dashboard.”
“Community-curated skill libraries installed via package managers will become standard infrastructure — as natural as installing a linting config. Skills is the early prototype of a skills ecosystem that will matter at scale.”
“Indie developers and freelancers who need to track Claude Code costs against client projects will love this. The project-level breakdown finally makes AI tool costs legible as a line item on a client invoice — something that's been surprisingly hard to do until now.”
“The writing and knowledge skills are underrated. The article-editing and Obsidian integration skills bring structured AI assistance to documentation workflows that most agent tools ignore entirely. Install even if you're not primarily a developer.”
