Ordinary code decides which files get reviewed and which rules apply; the AI model is used only for the judgment calls inside each file.

Its own benchmark claims higher precision than Claude Code on the same model using about one-ninth the tokens, while admitting it catches less.

The repo ships per-language rules — null-pointer and thread-safety for Java, XSS for JS/TS, SQL injection for database mapper XML.

Lead with the next action, number multi-step tasks, cap lists at five items, give real time estimates, and no “Hope this helps!” closer.

INSTALL.md has copy-paste steps for Claude Code, Codex, Cursor, Gemini CLI, Copilot, Zed, OpenCode, Kimi, Qwen, Grok and more.

A blind A/B test scored it 4.47 against 4.05 for the plain prompt, then the repo names its own failed release gate and two cases it made worse.

Flights from OpenSky and adsb.lol, ships via AISStream, 838 satellites from CelesTrak, USGS quakes, NASA fire detections, ~3,600 city cameras.

Click any plane and the camera locks on, then drops into a cockpit view that holds the terrain under you all the way down to the runway.

Thirteen of the fifteen layers are keyless; optional keys add live ships, fires, Google 3D cities and an OpenAI voice mode with 28 tools.

The README counts 68 specialized subagents, 292 on-demand skills and 94 command shims covering planning, review, build repair, security and docs.

Plan, capture a failing test, implement, review from a fresh context, verify, then save what it learned — each step leaves evidence behind.

A local Markdown memory vault carries context and handoffs between Claude Code, Codex, Kimi and other harnesses instead of re-pasting it.

Raw data runs in an isolated subprocess and only what the script prints enters the chat. The README benchmark shows 315 KB becoming 5.4 KB.

Every file edit, git action, task and error is logged to a local SQLite database, so the agent resumes instead of asking you to repeat yourself.

Claude Code, Cursor, Codex CLI, Gemini CLI, Copilot, Zed, Kiro and more, through MCP plus hooks that can block an unrouted command.

RAG means it finds the relevant passages in your files first, then has the model answer from those, with inline citations back to the source.

Wiki Mode has agents distill raw uploads into linked markdown pages with a knowledge graph, revision history and one-click rollback.

Docker Compose start, then swap in OpenAI, Gemini, DeepSeek, Anthropic or a local Ollama model, and pick your own vector database and storage.

The plugins/ directory holds 62, covering Figma, Notion, Slack, Stripe, Shopify, GitHub, Supabase, Vercel, Zoom, Datadog and more.

536 SKILL.md files hold the actual step-by-step instructions; Figma’s seven cover design-to-code, Code Connect and design-system rules.

marketplace.json offers 65 plugins to signed-in users; api_marketplace.json offers a narrower 49 to API-key users.

wt switch, wt list and wt remove replace the raw git incantations that make you type the branch name three times just to start.

wt switch -x claude -c feature-a -- 'Add user authentication' makes the branch, makes the folder, and launches Claude on that task in one line.

On APFS, btrfs and XFS, ten worktrees each get target/ and node_modules/ without rebuilding or copying them.

The pack front-ends the skills with slash commands: /spec, /plan, /build, /test, /constraints, /review, /webperf, /code-simplify and /ship.

Every skill ships an anti-rationalization table—the excuses agents use to skip a step, like “tests later,” each with a rebuttal.

“npx skills add addyosmani/agent-skills” installs the whole set; the README also documents native setups for nine tools, Claude Code through Codex.

Roughly 11,700 open issues sit against 80,700 already closed; about 7,700 were filed in the last month and only ~350 have gone untouched since June.

Ten of the repo’s thirteen GitHub Actions exist to manage issues, and two of them run Claude Code itself to label and de-duplicate every new report.

Version 2.1.275 syncs the skills and plugins on your claude.ai account into terminal sessions, and adds a ctrl+enter key that sends queued messages at once.
