★ 76k · +4.5k this week · MIT · updated 2026-10-02
7.9/10
What it does Archify is an Agent Skill that turns a codebase or a plain-text system description into an interactive diagram. The agent does not draw the SVG itself. It writes a typed JSON description of the system, and Archify's Node.js tooling checks it and compiles it into a single self-contained HTML file. You can ask for a diagram without… Read more →
Pros
- Deterministic compile and validation with machine-readable repair hints
- Single-file HTML output with tracing, themes and PNG/SVG/WebM export
- Architecture Delta view for reviewing design changes

Terse-output skill plus local proxy that trims the tokens coding agents write and read
★ 109k · +1.1k this week · Apache-2.0 · updated 2026-10-01
7.7/10
What it does Caveman cuts the tokens a coding agent spends, and it comes in two parts. The skill makes the agent answer in clipped, "caveman" prose. Code, commands, file paths and error messages stay exact, and security warnings and confirmations come back in full sentences. The optional proxy runs locally between your agent and the model provider. It compresses… Read more →
Pros
- Keeps code, paths and errors exact while cutting prose
- Local proxy compresses logs, diffs and JSON with recoverable originals
- Honest benchmarks, including where it loses
Cons
- Proxy engine is BSL-1.1 and the CLI sends anonymous telemetry by default
- Skill-only savings in agentic coding are modest

★ 2.9k · +32 this week · MIT · updated 2026-09-10
7.3/10
What it does Agent Rules Books, by Maciej Ciemborowicz, turns the ideas of well-known software engineering books into rule sets that a coding agent can follow. Instead of telling an agent to "follow Clean Code", you give it a concrete list of practices drawn from that book. The rules are the author's own wording, not quotes from the books, and… Read more →
Pros
- Fourteen rule sets in mini, nano and full sizes to fit any context budget
- Plain Markdown with a SKILL.md per book, no scripts to run
Cons
- Rules are one author's interpretation, not official book material; evidence of benefit is a single informal experiment

★ 95k · +495 this week · Apache-2.0 · updated 2026-10-02
7.2/10
What it does Claude-Mem, by Alex Newman, gives Claude Code a long-term memory that lasts across sessions. It hooks into the session lifecycle, records what the agent does with its tools, and uses a model to compress those records into short observations and summaries. It then injects the relevant parts into later sessions. The result is that a new session… Read more →
Pros
- Automatic capture and injection of past session context
- Token-efficient layered search over SQLite and Chroma
- Private tags and local-only mode available
