01
Infrastructure

codebase-memory-mcp

DeusData/codebase-memory-mcp

A local MCP server that builds code intelligence from Tree-sitter parsing and a graph, with a static binary and support for many programming languages.

8,997
Stars total / C
4,212 stars this week

A first test

Install the binary and index a small repository. Ask for a symbol definition and callers, compare both with the source, and check the MCP client permissions before enabling edits.

02
Infrastructure

headroom

headroomlabs-ai/headroom

A library, proxy, and MCP server that compresses tool output, logs, files, and retrieval chunks before they reach an LLM.

40,953
Stars total / Python
12,793 stars this week

A first test

Run it on a captured tool response and compare the original and compressed text. Measure whether key fields survive, then add a regression test before using it in an agent loop.

03
Agent Ops

Agent-Reach

Panniantong/Agent-Reach

A command-line skill that gives agents access to web pages and services such as X, Reddit, YouTube, GitHub, Bilibili, and Xiaohongshu through fallback backends.

35,582
Stars total / Python
8,324 stars this week

A first test

Install it and fetch one public post from one supported service. Check the returned URL, timestamp, and text against the source before using it in a report.

04
Open Source

iptv

iptv-org/iptv

A community-maintained collection of public IPTV channel playlists, grouped by country, language, and category.

126,091
Stars total / TypeScript
8,035 stars this week

A first test

Open the supplied M3U URL in a test player and check one channel's source and licence. Remove unavailable or unauthorised streams before sharing a playlist.

05
Security

SkillSpector

NVIDIA/SkillSpector

A security scanner for agent skills that checks for prompt injection, data exfiltration, unsafe commands, and supply-chain risks before installation.

8,559
Stars total / Python
5,026 stars this week

A first test

Install it with uv tool install and scan one skill directory. Read each finding, reproduce the flagged path, and block the skill until its network and file actions are understood.

06
Open Source

iroh

n0-computer/iroh

A Rust networking library for encrypted QUIC connections and NAT traversal that lets peers dial by public key instead of a fixed address.

10,335
Stars total / Rust
1,502 stars this week

A first test

Run the echo example on two local processes. Record the public keys and connection path, then test a blocked-network case before exposing a service to the Internet.

07
Agent Ops

agent-skills

addyosmani/agent-skills

A pack of 24 workflow skills for definition, planning, implementation, testing, review, performance, simplification, and release work in coding agents.

63,960
Stars total / JavaScript
7,170 stars this week

A first test

Install the pack with npx skills add addyosmani/agent-skills. In one real repo, run /spec, /plan, and /test on a small change, then keep it if the outputs provide useful evidence.

08
Creative Systems

system_prompts_leaks

asgeirtj/system_prompts_leaks

A reference corpus of collected system-prompt files from several AI products and agents. It is useful for comparing instruction layers, but the files are not official guarantees.

43,803
Stars total / JavaScript
1,682 stars this week

A first test

Read one prompt as a text sample and label its source and date. Compare its rules with the product's public documentation, and do not copy private or product-specific text into a deployed system.

09
Data & Research

timesfm

google-research/timesfm

A pretrained time-series forecasting model and Python package for predicting future values from historical time-series data.

24,353
Stars total / Python
3,335 stars this week

A first test

Install the package and forecast a small, dated dataset with a held-out period. Compare the result with a seasonal baseline and record the horizon and input frequency.

10
Agent Ops

pm-skills

phuryn/pm-skills

A set of product-management skills and commands for discovery, strategy, planning, execution, launch, and growth workflows.

19,999
Stars total / None
3,025 stars this week

A first test

Install one skill and apply it to a real but low-risk feature. Compare its problem statement, acceptance criteria, and launch checks with your existing brief before adopting more commands.

11
Infrastructure

meshery

meshery/meshery

A cloud-native management platform for designing, operating, and visualising Kubernetes and other multi-cluster infrastructure with GitOps workflows.

11,170
Stars total / TypeScript
879 stars this week

A first test

Run it against a local Kubernetes cluster and import one non-production workload. Check the generated manifest and access scope before connecting a shared cluster.

12
Open Source

swc

swc-project/swc

A Rust-based compiler toolkit for parsing, transforming, and compiling JavaScript and TypeScript, with libraries and tools for high-speed builds.

34,077
Stars total / Rust
545 stars this week

A first test

Build one example transform and compare its output with the source test. Run the project's test command before replacing a compiler in an existing build pipeline.
