>> MISSION_PARAMETERS

  • ACTIVE Building vibetags, Java annotations that tell Claude, Cursor and Codex which code they are not allowed to touch
  • LAB Making concurrency bugs reproducible instead of lucky with async-test-lib
  • SHIELD Running a local prompt injection firewall between my tools and every LLM API
  • UPLINK Ask me about Java, AI guardrails, static analysis, MCP servers, and why a green test suite is not proof
  • COMMS Reach me at isberg.peter@gmail.com or deversity.se

SUPPORT Docker GitHub Actions Claude Model Context Protocol Linux IntelliJ IDEA

>> PRIMARY_TARGETS

RepoStarsWhat it does
vibetags stars Java annotations as AI guardrails. Mark the code an agent must not rewrite, and it stops rewriting it.
async-test-lib stars Forces concurrency bugs to happen using synchronized barriers, then names the one that fired.
llm-fw stars Local prompt injection firewall. Malicious prompts are blocked and logged, clean ones pass through.
skill3 stars Relearns a technical skill for an agent, anchored to a target model cutoff, and vets the result.
codekoll stars Static analyzer for Java that finds the bugs which compile perfectly and detonate in production.
codekarta stars Parses Java source and emits SVG maps: call graphs, exception flow, state machines.
axiom stars The codebase as a live queryable graph, so an agent can see what it just broke.
blindbean stars Homomorphic encryption hidden behind ordinary Java objects and annotations.
ghost-mcp stars MCP server that exposes OS level UI automation to AI clients.
