About
Internal plugins built by Anthropic (agent-sdk-dev, code-review, feature-dev, mcp-server-dev, plugin-dev, pr-review-toolkit, security-guidance, skill-creator, math-olympiad, plus a full set of LSP plugins for major languages). README explicitly notes there is no top-level LICENSE — read each linked plugin's LICENSE before mirroring or installing.
Pre-publish audit for ClawHub skills. Nine checks, one verdict: READY or FIX FIRST. Pass the security scan on the first upload.
Find and verify real research papers through a keyless index — no login or API key from a normal IP. Search by topic or method, map a field's citation graph, pull the in-body passages that prove a claim, or scan GitHub for engineering prior art. Grounds every answer in papers the index actually returns — never invents titles or arXiv IDs.
A system, not a pile of skills. Six skills + orchestrator + shared project memory: validate, position, audit (write-mode), launch. $99 once.
